Decision 3183-D01-2015
TransAlta MidAmerican Partnership Proceeding 3183
Sundance 7 Power Plant Application 1610492-1
1 Introduction
1. In this decision, the Alberta Utilities Commission must decide whether to approve an
application by TransAlta MidAmerican Partnership1 to construct and operate an 856-megawatt
(MW) combined-cycle natural gas and steam generation facility designated as Sundance 7.
2. Sundance 7 (the project or proposed power plant) is proposed to be located in the
Lake Wabamun area, in a greenfield site in the west half of Section 10, Township 52, Range 4,
west of the Fifth Meridian, approximately seven kilometres southwest of the village of Wabamun
and in close proximity to TransAlta Corporation’s existing coal-fired power generation facilities
(the project site). TransAlta MidAmerican Partnership (TAMA Power or the applicant) filed its
application pursuant to Section 11 of the Hydro and Electric Energy Act. The location proposed
for this project is shown on the following map:

1.1 Project description
3. Sundance 7 is described in the application as an 856-MW combined-cycle natural gas
and steam generation facility, capable of being operated as a base load power plant and designed
to operate at full capability for sustainable periods of time. The project consists of two natural
gas combustion turbine generators, two heat recovery steam generators and one steam turbine
generator. Natural gas would be delivered to the project site via a pipeline to a gas metering
station also located on the project site.
4. Sundance 7 is proposed to be located in Parkland County in an area of high industrial
activity, that includes active mines and power generation facilities. Existing industrial facilities
located in the area include TransAlta’s existing Sundance Generating Facility units 1 to 6,
Keephills Generating Facility units 1 to 3 and the Highvale Coal Mine, and other facilities owned
and/or operated by Zargon Oil and Gas Ltd., New Star Energy Ltd., and ATCO Gas and
Pipelines Ltd.
5. TAMA Power stated that the project would allow TransAlta (through TAMA Power) to
continue supporting the local economy and the existing labour force. If approved, the proposed
power plant would create approximately 500 jobs during construction and another 35 full-time
positions during operations.2
6. TAMA Power anticipates an in-service date of December 2018. Sundance 7 would be
interconnected to the Alberta Interconnected Electric System through AltaLink Management
Ltd.’s 500-kilovolt network. AltaLink Management Ltd. would file a separate application with
the Commission to consider the transmission facilities required for the interconnection.
7. During the course of the proceeding TAMA Power made various commitments, a list of
which is attached as Appendix J.
1.2 Background
8. TAMA Power filed its application with the Commission to construct and operate
Sundance 7 on April 23, 2014. The application was registered as Application 1610492-1 and
Proceeding 3183.
9. The Commission issued information requests to TAMA Power on May 15, 2014, and
August 19, 2014. TAMA Power provided responses to the Commission on August 7, 2014, and
September 5, 2014.
10. The Commission issued a notice of application on September 10, 2014. An information
session was held by the Commission in Stony Plain, Alberta on October 2, 2014. In response to
its notice, the Commission received statements of intent to participate from the following parties:
Ferne Cymbaluk
Philip Cymbaluk
David Cymbaluk
Tammi Cymbaluk Breymann
Summer Village of Kapasiwin

11. Ferne Cymbaluk, Philip Cymbaluk, David Cymbaluk and Tammi Cymbaluk Breymann
(the Cymbaluk family) formed a group (the Cymbaluks). Subsequently, Donna Thomas and the
Summer Village of Kapasiwin joined the Cymbaluks.
12. The Commission received letters in support of the project from the Village of Wabamun,
Parkland County, the Resource Industry Suppliers Association and the Building Trades of
Alberta.
13. The Commission issued its ruling on standing and a notice of hearing on
December 11, 2014. The parties who were granted standing are listed in Appendix A. The
Commission’s standing ruling is attached as Appendix C.
14. By letter dated February 20, 2015, the Paul First Nation requested to participate in the
proceeding. The Paul First Nation was concerned with, among other things, the cumulative
impacts to its aboriginal and treaty rights from increased traffic, noise and activity caused by the
project. The Paul First Nation submitted that its members conducted hunting, trapping, gathering
and other traditional activities on this land and requested more time to hire a third party to assess
the compounding impact of the project on its traditional lands.
15. On February 27, 2015, the Commission issued a ruling with respect to the standing of
the Paul First Nation.3 In its ruling, the Commission determined that the Paul First Nation
qualified for standing in the proceeding based on the nature of the project and associated
impacts, and the assertion of a land-based claim with respect to land located within 800 metres of
the project site. The Commission also granted the Paul First Nation a one-week extension for the
filing of its evidence. The Commission’s ruling is attached as Appendix D.
16. In its standing rulings, the Commission assumed, without deciding, that both the
Gunn Métis and the Paul First Nation were entitled to exercise the rights they asserted.
17. The notice of hearing provided details of the application and scheduled the remaining
process steps.
18. The hearing commenced on Monday, April 13, 2015, in Stony Plain, Alberta before
Commission members Tudor Beattie, QC (Panel Chair) and Anne Michaud, and Acting
Commission member Kate Coolidge. The hearing adjourned in Stony Plain on April 17, 2015,
and resumed in Edmonton from April 20 to 21, 2015.

19. Although most of the hearing was conducted in a public session, a portion of the
evidence was subject to a confidentiality order pursuant to a request from the Gunn Métis and
was heard accordingly.
20. The Cymbaluk family (Ferne, Philip, David and Tammi Cymbaluk Breymann), the
Summer Village of Kapasiwin, the Gunn Métis and the Paul First Nation participated in the
hearing.
2 Role and authority of the Commission
21. The Commission regulates the construction and operation of power plants in Alberta.
Section 11 of the Hydro and Electric Energy Act states that no person may construct or operate a
power plant without prior approval from the Commission.
22. When considering an application for a power plant, the Commission is guided by
sections 2 and 3 of the Hydro and Electric Energy Act, and Section 17 of the Alberta Utilities
Commission Act.
23. Section 2 lists the purposes of the Hydro and Electric Energy Act in the generation of
electric energy. Those purposes include:
to provide for the economic, orderly and efficient development and operation, in
the public interest, of the generation of electric energy in Alberta;
to secure the observance of safe and efficient practices in the public interest in the
generation of electric energy in Alberta; and
to assist the government in controlling pollution and ensuring environment
conservation in the generation of electric energy in Alberta.
24. Section 3 of the Hydro and Electric Energy Act requires the Commission to have regard
for the purposes of the Electric Utilities Act when assessing whether a proposed power plant is in
the public interest. The purposes of that act include the development of an efficient electric
industry structure and the development of an electric generation sector guided by competitive
market forces.4
25. In Alberta, the legislature expressed its intention that electric generation is to be
developed through the mechanism of a competitive, deregulated electric generation market.
Section 3 of the Hydro and Electric Energy Act states that the Commission shall not have regard
to whether the proposed power plant “…is an economic source of electric energy in Alberta or to
whether there is a need for the electric energy to be produced by such a facility in meeting the
requirements for electric energy in Alberta or outside of Alberta.” Accordingly, in considering an
4 Electric Utilities Act, Section 5.
Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 5
application before it, the Commission does not take into account the potential need and cost of a
project.5
26. As such, in the following assessment of whether the project is in the public interest, the
Commission has not had regard to whether there is a need for the project proposed by the
applicant. In considering this application, the Commission was also mindful of Section 19 of the
Hydro and Electric Energy Act, which gives it the power to approve an application, approve it
with conditions, or deny it.
27. The Commission’s public interest mandate is found in Section 17 of the Alberta Utilities
Commission Act, which states:
Public interest
17(1) Where the Commission conducts a hearing or other proceeding on an application to
construct or operate a hydro development, power plant or transmission line under the
Hydro and Electric Energy Act or a gas utility pipeline under the Gas Utilities Act, it
shall, in addition to any other matters it may or must consider in conducting the hearing
or other proceeding, give consideration to whether the construction or operation of the
proposed hydro development, power plant, transmission line or gas utility pipeline is in
the public interest, having regard to the social and economic effects of the development,
plant, line or pipeline and the effects of the development, plant, line or pipeline on the
environment.
28. In Decision 2001-111,6 the Commission’s predecessor, the Alberta Energy and Utilities
Board (EUB or the Board), explained its approach to assessing whether the approval of a power
plant is in the public interest, as follows:
The determination of whether a project is in the public interest requires the Board to
assess and balance the negative and beneficial impacts of the specific project before it.
Benefits to the public as well as negative impacts on the public must be acknowledged in
this analysis. The existence of regulatory standards and guidelines and a proponent’s
adherence to these standards are important elements in deciding whether potential
adverse impacts are acceptable. Where such thresholds do not exist, the Board must be
satisfied that reasonable mitigative measures are in place to address the impacts. In many
cases, the Board may also approve an application subject to specific conditions that are
designed to enhance the effectiveness of mitigative plans. The conditions become an
essential part of the approval, and breach of them may result in suspension or rescission
of the approval.
In the Board’s view, the public interest will be largely met if applications are shown to be
in compliance with existing provincial health, environmental, and other regulatory
standards in addition to the public benefits outweighing negative impacts.

6 • Decision 3183-D01-2015 (June 9, 2015)
29. The Commission is of the view that this approach to assessing whether a proposed
power plant is in the public interest remains consistent with the purpose and intent of the
statutory scheme.
30. Further, Rule 007: Applications for Power Plants, Substations, Transmission Lines,
Industrial System Designations and Hydro Developments applies to applications for a power
plant governed by the Hydro and Electric Energy Act. The application must meet the
informational and other requirements set out in Rule 007. Specifically, an applicant must provide
technical and functional specifications, information on public consultation and environmental
information, including a noise assessment. The requirements relating to noise control are set out
in Rule 012: Noise Control. The applicant must also receive all approvals required pursuant to
other applicable provincial and federal legislation.
3 Evidentiary matters
3.1 Admissibility of expert evidence
31. Expert evidence is opinion evidence on a scientific, technical or otherwise specialized
matter provided by a person with specialized knowledge, experience or training. The Supreme
Court of Canada succinctly explained the role of an expert witness in R. v. Howard when it
stated: “Experts assist the trier of fact in reaching a conclusion by applying a particular scientific
skill not shared by the judge or the jury to a set of facts and then by expressing an opinion as to
what conclusions may be drawn as a result.”7
32. The Supreme Court of Canada set out the test for admissibility of expert evidence in
R. v Mohan.8 To call expert evidence, a party must demonstrate that the evidence is relevant,
necessary to assist the decision maker, and is not subject to an exclusionary rule.9
33. Another important factor when considering expert evidence is the expert’s independence
and objectivity. On April 30, 2015, the Supreme Court of Canada issued a judgement
White Burgess Langille Inman v. Abbott and Haliburton Co., 2015 that directly addressed expert
evidence and its relationship between independence, admissibility and weight:10 The Supreme
Court found that expert witnesses have a special duty to the court to provide fair, objective and
non-partisan assistance:
Underlying the various formulations of the duty are three related concepts: impartiality,
independence and absence of bias. The expert’s opinion must be impartial in the sense
that it reflects an objective assessment of the questions at hand. It must be independent in
the sense that it is the product of the expert’s independent judgment, uninfluenced by
who has retained him or her or the outcome of the litigation. It must be unbiased in the
sense that it does not unfairly favour one party’s position over another. The acid test is
whether the expert’s opinion would not change regardless of which party retained him or
her…11

34. The Commission commented on the weighing of expert evidence in
Decision 2011-436:12
… When deciding what weight to give to the evidence provided by an expert witness, an
important factor the Commission will consider is whether the expert witness provided an
independent or objective opinion. The role and duties of an expert witness was
considered in an English case known as The Ikarian Reefer.13 That case and its
implications were extensively discussed in 1159465 Alberta Ltd. v. Adwood
Manufacturing Ltd., a recent decision of the Alberta Court of Queen’s Bench. The court
summarized in part the duties and obligations of an expert witness, as described in the
Ikarian Reefer, as follows:
1. Expert evidence presented to the Court should be and should be seen to be the
independent product of the expert uninfluenced as to form or content by the
exigencies of litigation ...
2. An expert witness should provide independent assistance to the Court by way of
objective unbiased opinion in relation to matters within his expertise ... An expert
witness in the High Court should never assume the role of advocate… [Emphasis
added in the court’s decision.]14
35. In the event that the Commission finds that an expert’s evidence extends beyond the
limits of his or her expertise, the Commission will take the approach outlined in
Decision 2012-303:15
…evidence provided by [an expert] in areas where he was clearly not qualified to opine,
will be given the weight of a lay witness rather than the weight of a properly qualified
expert in these areas. Where that evidence diverges from the evidence of a properly
qualified expert witness, the evidence of the qualified expert witness will be preferred.16
36. The Commission has adopted the approach described above when weighing the expert
evidence proffered in this proceeding.
3.1.1 The expert evidence tendered in this proceeding
37. By letter dated April 6, 2015, the Commission advised the parties that it had dispensed
with the need to qualify expert witnesses17 and that it would not be necessary for counsel to
request that their respective witnesses be qualified as an “expert” witness with regard to their
pre-filed written evidence or testimony at the oral hearing. The Commission instructed the
parties to file the curriculum vitae for their respective witnesses, in order for the Commission to
be able to assess the weight attributable to the relevant evidence and opposing counsel may
question a witness’ qualifications and credibility.

38. The Commission also indicated in its April 6th letter that cost claims submitted by
eligible intervener parties for consultants’ fees are not dependent upon those consultants being
formally qualified as expert witnesses. A copy of the Commission’s letter is attached as
Appendix E.
39. TAMA Power, the Gunn Métis and the Cymbaluks each tendered expert evidence in
support of their respective positions.
40. TAMA Power’s expert witnesses were Dr. Rick Robinson, Dr. Don Davies,
Chris Madland, James Wilkinson, Victor Young, and Corey De La Mare. James Farquharson and
James Benya appeared as expert witnesses for the Cymbaluks. Andrew Read,
Dr. Joseph C. Vipond and Karen Kubiski appeared as expert witnesses for the Gunn Métis.
41. TAMA Power argued that the Commission should give little weight to the opinion
evidence of the interveners’ experts because those experts lacked the necessary expertise in the
field outlined in their reports. The weight of the consultants’ evidence presented in the
proceeding is discussed in greater detail in the relevant sections of this decision.
42. The Cymbaluks questioned the weight that the Commission should give to the evidence
of TAMA Power’s noise consultant, Mr. Young. Neither the Gunn Métis nor the Paul First Nation
made submissions relating to TAMA Power’s consultants.
3.1.2 Commission findings
43. The Commission heard expert opinion evidence on a host of subjects related to the
project. This evidence was presented on behalf of the applicant, the Cymbaluks and the
Gunn Métis.
44. No party submitted that any expert evidence should be excluded.
45. Because the Supreme Court of Canada issued the White Burgess decision after the
completion of the oral portion of the public hearing, none of these witnesses were specifically
asked if they could each fulfill their duty to provide fair, objective and non-partisan evidence.
Notwithstanding, the Commission is satisfied that each of the experts who gave evidence in the
proceeding was able and willing to carry out his or her respective duty to provide the
Commission with fair and objective evidence. Accordingly, the Commission finds that all of the
expert evidence filed met the threshold for admissibility from the perspective of independence.
46. The Commission finds that the witnesses listed below provided evidence that was
consistent with their expertise and in a relatively objective manner. These experts demonstrated
considerable knowledge of the issues raised in the hearing and demonstrated some flexibility in
the views and positions that they presented to the Commission. The Commission found these
witnesses to be credible and, subject to the exceptions discussed later in these findings, their
evidence to be useful.

47. The Commission is satisfied that Dr. Vipond is a licenced medical doctor with
experience in emergency medicine. It is clear to the Commission that he has taken considerable
interest in the issue of health effects from air emissions. His written evidence also included his
interpretation and discussion of numerous published epidemiological reports and studies of air
emissions. However, it is the Commission’s view that Dr. Vipond lacks the necessary skills,
experience and training to comment on the interpretation of epidemiological studies or air
emissions modelling. Consequently, it gave little weight to this aspect of his evidence.
4 Pre-hearing motions and procedural matters
4.1 The Gunn Métis’ request for confidential treatment of maps
48. On October 16, 2014, the Gunn Métis requested confidential treatment of two maps
identifying aboriginal harvesting locations within two kilometres of the project, pursuant to
Section 13 of Rule 001: Rules of Practice. The Gunn Métis submitted that if these maps were
made public, it could potentially result in a real and substantial risk of harm to its members’
ability to earn their livelihood because aboriginal harvesting locations are used for subsistence,
income and cultural purposes.18
49. In a letter dated October 29, 2014,19 the Commission ruled on the motion and, for the
reasons specified in that ruling, found that the maps identifying the location of harvesting
grounds fell under the category of personal information. The Commission accepted that the maps
satisfied the three-part test set out in Section 13(4)(b) of Rule 001, namely that the maps are
personal in nature and have been consistently treated as confidential by the Gunn Métis, and that
the Gunn Métis’ interest in keeping this information confidential outweighs the public’s interest
in the disclosure of this information.
50. The Gunn Métis also sought the Commission’s leave to file the maps after the deadline
for submissions had past, should the confidentiality ruling be granted. The Commission granted
the Gunn Métis’ request and allowed the Gunn Métis to file the maps by November 4, 2014. A
copy of the October 29, 2014 ruling is attached as Appendix F.
4.2 Gunn Métis Local 55: Confidentiality request for will-say statements
51. On February 18, 2015, the Gunn Métis filed a motion requesting that the will-say
statements of its members and associated maps be treated as confidential pursuant Section 13 of
Rule 001.20 The Gunn Métis submitted that these statements and maps contained personal
information that must be kept private because they included the location of aboriginal harvesting
grounds.

52. On February 26, 2015, the Commission issued a ruling granting the Gunn Métis’ request
for confidential treatment of its will-say statements and associated maps. A copy of the ruling is
attached as Appendix G.21
4.3 Cymbaluks: Motion for further and better responses to information requests
53. Legal counsel for the Cymbaluks filed a motion on February 5, 2015, requesting that
TAMA Power provide further and better responses to the information requests of the
Cymbaluks.22 The Commission denied the Cymbaluks’ motion. In its February 20, 2015 ruling,23
the Commission found that TAMA Power’s responses to the information requests were adequate
in relation to the application and that providing further responses to the information requests may
unduly burden TAMA Power, given the stage of the proposed power plant design.
54. The Cymbaluks also requested an extension of the intervener evidence submission
deadline to one week after full and complete answers to their information requests had been
provided. The Commission granted the Cymbaluks’ request, finding that a slight amendment to
the process schedule would not prejudice any party involved in the proceeding. A copy of the
ruling is attached as Appendix H.
4.4 Cymbaluks: Motion to file late evidence
55. The Cymbaluks filed a motion on March 16, 2015, in which they requested to submit
further intervener evidence after the deadline for filing submissions had past.24 In their request,
made pursuant to Rule 001, the Cymbaluks sought permission to file an FDI Acoustics Inc.
expert report related to noise modelling. The Cymbaluks explained that the noise modelling
would be filed as soon as it became available and that notice was provided in their evidence that
such information was to be filed.
56. The Commission ruled on March 24, 2015, allowing the FDI Acoustics Inc. report to be
admitted as evidence.25 The Commission considered that no party objected to the report being
filed as evidence and found that the report was relevant to the issues raised in the proceeding. A
copy of the ruling is attached as Appendix I.
5 Discussion of the issues
57. In this proceeding and during the seven-day oral hearing, the Commission heard and had
to consider evidence on a number of issues relating to the project. The significant issues such as
consultation, noise, air emissions, health effects, environmental effects, construction and traffic,
safety, and visual impacts are addressed below.
58. In its submissions, the Gunn Métis asked the Commission to consider the
“Lac Ste. Anne Métis' Section 35 rights and the impacts to those rights as part of its Section 17
decision regarding the public interest.”26 However, a question of constitutional law was not

raised by the Gunn Métis,27 nor was it advanced by the Paul First Nation. Consequently, the
Commission makes no determination on the existence of aboriginal rights of these aboriginal
groups in this decision.
59. In making its decision, the Commission has taken into account the evidence and
submissions regarding potential direct and adverse impacts of the proposed power plant
advanced by the interveners. In reaching the determinations set out in this decision, the
Commission has considered all relevant materials comprising the record of this proceeding,
including the evidence and submissions provided by each party. References in this decision to
specific parts of the record are intended to assist the reader in understanding the Commission’s
reasoning relating to a particular matter and should not be taken as an indication that the
Commission did not consider all relevant portions of the record as it relates to that matter.
6 Consultation
60. The Commission prescribes consultation requirements for applicants in Rule 007.
Appendix A of Rule 007, Participant Involvement Program Requirements, requires applicants for
power plants to include a description of their participant involvement program in their
application.
61. The purpose of a public consultation program is to inform parties whose rights may be
directly and adversely affected by a proposed application. Appendix A of Rule 007 specifies that
a participant involvement program must be conducted before an application is filed and should
include the distribution of a project-specific information package, responses to questions and
concerns raised by potentially-affected persons, and a discussion of options, alternatives and
mitigation measures.
6.1 Views of the applicant
62. TAMA Power stated that it developed a public involvement program for the project to
build and maintain transparent and respectful relationships with stakeholders, establish a high
level of inclusiveness when determining potentially affected parties, seek input into the design of
the consultation process, provide timely and accurate project information, ensure stakeholders
have an opportunity to raise concerns and discuss potential mitigation measures, and provide
feedback to stakeholders on how their input was considered.28
63. TAMA Power’s public involvement program consisted of, among other things, public
notification, personal consultation, and open houses. Consultation commenced in
November 2013 with communications and engagements with nearby landowners, local and
regional groups, municipalities, Members of the Legislative Assembly of Alberta and Ministers,
aboriginal groups, and provincial and federal agencies.
64. A project information package was delivered to stakeholders, a project-specific website
was created, and a news release was issued in January 2014. The information package contained
a letter, a project information booklet, and the Commission’s Public Involvement in Needs and

Facilities Applications brochure, and was sent to 498 stakeholders, including aboriginal groups.29
Recipient stakeholders included municipal governments such as the Village of Wabamun,
Parkland County, the City of Spruce Grove, the Town of Stony Plain, the Summer Village of
Betula Beach, the Summer Village of Point Alison, the Summer Village of Kapasiwin, the
Summer Village of Lakeview; regional groups such as the Committee on Keephills Environment
(COKE), the Mewassin Community Action Council, the Wabamun Watershed Management
Council, and the North Saskatchewan Watershed Alliance; the Parkland School Division;
Keephills School; Alberta Environment and Sustainable Resource Development (ESRD); the
Canadian Assessment Agency; local interveners within 2,000 metres of the project site boundary,
and residents within the T0E 0N0 postal code.
65. Open houses were held on February 4, 2014, at the Sundance Training Center in
Parkland County and at the Paul First Nation School on April 2, 2014. At each open house,
TAMA Power presented information about the project such as the project schedule, air quality,
noise, other environmental impacts and traffic. Staff responded to questions on the project’s
location, water usage, and air emissions.
66. TAMA Power conducted personal consultation with all landowners, residents, and
occupants within 800 metres of the project site boundary, and notified residents within
2,000 metres of the project site boundary, the Paul First Nation, and the Enoch Cree Nation.
TAMA Power also presented project information to COKE and the Wabamun Watershed
Management Council.
67. Throughout the consultation process, TAMA Power heard concerns about traffic, air
emissions, cumulative effects, light emissions, visual sightlines, visible plume, noise,
socio-economic issues, rare plants, traditional land use, and water and aquatic resources.
TAMA Power stated it took these concerns into account during the preliminary engineering
phase of the proposed power plant and is considering an additional open house to address
construction-related concerns.
68. Members of the Cymbaluk family were the only parties that objected to the project
during personal consultation. TAMA Power stated that it has a long-standing relationship with
the Cymbaluk family and had met with its members to introduce the project, and to discuss their
concerns and mitigation measures. TAMA Power had preliminary discussions with the family
members about a buyout of their property located adjacent to the project site but could not come
to an agreement. The Cymbaluk family identified concerns regarding noise, risk, lighting, traffic,
plume and emergency response planning. TAMA Power submitted that it has been listening to
the Cymbaluk family’s concerns and has adopted numerous mitigation measures to address those
concerns.
69. TAMA Power conducted its First Nations engagement based on the direction provided
by the Aboriginal Consultation Office, which informed TAMA Power that because the project
was on private land, it was on the lower end of the consultation spectrum. The Aboriginal
Consultation Office consequently directed TAMA Power to notify the Paul First Nation and the
Enoch Cree Nation. It also directed TAMA Power to conduct a full consultation if a request was
made for more information and a determination made that the project could adversely affect
treaty rights.

Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 13
70. TAMA Power’s consultation with the Gunn Métis began after a Gunn Métis member
contacted TAMA Power in February 2014 to state that the Gunn Métis was an aboriginal group
with major concerns about Sundance 7, amongst other things.30 A meeting was held on
March 18, 2014, between the Gunn Métis and TAMA Power representatives from the
Aboriginal Relations Office. On March 20, 2014, an email was sent by the Gunn Métis to
TransAlta’s executives outside of the aboriginal relations group, including its Chief Executive
Officer. This email was seen by TAMA Power as a relationship-breaking move.
71. TAMA Power reached out to the Gunn Métis after it was granted standing by the
Commission in December of 2014. At the hearing, TAMA Power stated that it would like to get
to know the Gunn Métis community and its members better and has committed to meet again to
start that process and develop a long-term relationship.31
72. TAMA Power stated that TransAlta has had a long standing relationship with the
Paul First Nation and have supported the community through education, employment and
support for community wellness.
73. TAMA Power’s consultation began in October 2013 with the Paul First Nation.
TAMA Power submitted that extensive consultation had taken place and filed its consultation
records detailing the various discussions and meetings with the Paul First Nation. According
to TAMA Power, the Paul First Nation requested an open house for their community,
which TAMA Power held on April 2, 2014. A total of 79 participants signed-in at the open
house, where information was presented and questions were answered. After the open house,
TAMA Power contacted the Paul First Nation on numerous occasions, offering a follow-up
meeting to see if there were any questions about the project. On July 18 and September 24, 2014,
TAMA Power met with the Paul First Nation and stated that no concerns were raised. From
October to December, 2014, the Paul First Nation entered into its election period. During this time,
the band manager left and communication between the parties became a challenge.32
74. The Paul First Nation filed its statement of intent to participate on February 20, 2015, in
which it expressed concerns with air emissions, environmental and health effects, unemployment
and the loss of traditional land values and use, amongst other things. TAMA Power indicated
that until this time, it was unaware that the Paul First Nation objected to the project.
75. TAMA Power submitted that the concern about gravesites raised by the Paul First Nation
at the hearing, had not arisen prior, during its extensive consultations with the Paul First Nation.
6.2 Views of the Cymbaluks
76. The Cymbaluk family stated that TAMA Power was unwilling or unable to fully and
adequately address their concerns.33 The family has made multiple noise complaints to TransAlta
about other facilities in the area and, while these complaints were not related to the project, the
Cymbaluk family and TransAlta have been in contact. There have been many exchanges of
emails, phone calls and in-person meetings. The Cymbaluk family stated that family members

would often call TransAlta instead of sending an email, because that appeared to be TransAlta’s
preferred method of contact.
77. The Cymbaluk family submitted that TransAlta representatives have never sat down and
tried to resolve their issues, and only provided reasons and excuses.34 The Cymbaluk family
stated that, for this reason, it could not trust TransAlta or TAMA Power.
6.3 Views of the Gunn Métis
78. The Gunn Métis submitted that TAMA Power’s participant program had fallen short
and, given the nature of the issues, more consultation should be required because the Gunn Métis
was not given an opportunity to consult with TAMA Power to ensure its concerns were being
addressed.35 The Gunn Métis added that it had virtually no contact with TAMA Power prior to
filing its statement of intent to participate with the Commission.
79. While TAMA Power may not have been aware of the Gunn Métis early on, the
Gunn Métis expected that TAMA Power would welcome it and facilitate its involvement in the
ongoing public consultation processes.
80. The Gunn Métis indicated that it attempted to engage with TAMA Power before the
application was filed but that TAMA Power did not reciprocate or show an openness to act in a
collaborative fashion until late January 2015, as the date of the hearing fast approached. If
TAMA Power had involved the Gunn Métis in consultation and addressed its concerns, its
participation in the hearing would have been avoided.
81. The Gunn Métis stated that it learned that TAMA Power generally gets to know the
community first and then identifies the aboriginal community’s priorities. Once those are known,
TAMA Power can support the well-being of the community. The Gunn Métis stated it does not
like this approach, adding that it is represented by a group of volunteers that did not have time to
attend meetings that did not appear to be productive.36
82. The Gunn Métis emailed TAMA Power on February 24, 2014, to request a meeting. The
Gunn Métis met with representatives of TAMA Power and TransAlta regarding Sundance 7 and
TransAlta’s other operations in the area on March 18, 2014. Following that meeting, the
Gunn Métis and TransAlta tried to schedule another relationship-building meeting.
83. The Gunn Métis stated that it contacted TransAlta executives by email on
March 20, 2014, to ensure its concerns were being heard by decision-makers within the company
and to attempt to establish leadership-to-leadership communication. The Gunn Métis stated that
it had done this successfully with other proponents in the past and had been encouraged by other
proponents to do so.37 The Gunn Métis stated that it was unaware that this action was seen as a
relationship-breaking move38 and that it was not told to deal only with the aboriginal relations
group. It added that it did not hear back from TAMA Power until after it was granted standing.
Subsequently, on March 27, 2015, TAMA Power and the Gunn Métis met to discuss the project.

Decision 3183-D01-2015 (June 9, 2015) • 15
84. The Gunn Métis requested “some direction from the Commission to ensure that TAMA
engages meaningfully and concretely with the Local.”39
85. The Gunn Métis requested capacity funding from TAMA Power, stating that such
funding would assist with technical and other support to conduct studies to enable it to fully
engage in understanding and collaboratively designing mitigations to avoid impacts to its rights
and to address other community concerns.40
86. The Gunn Métis also requested that, as a condition for approval of construction and
operation of Sundance 7 “…construction not be undertaken until the Gunn Métis Local and
TAMA have jointly reported to the Commission that they believe that the participant
involvement program requirements have been fulfilled and are able to provide the Commission
with a list of concrete mitigations and accommodations agreed to for Sundance 7 as well as
agreed-to processes to manage the relationship moving forward.”41
87. The Gunn Métis requested, among other things, that it wished to engage TAMA Power
representatives in a full-day workshop focused on topics to facilitate knowledge sharing.
6.4 Views of the Paul First Nation
88. In its statement of intent to participate, the Paul First Nation expressed concerns with air
emissions, environmental and health effects, unemployment and the loss of traditional land
values and use. At the hearing, the Paul First Nation stated that it was concerned with the
potential for graves on the project site.
89. The Paul First Nation stated that TAMA Power and TransAlta have supported the
community and acted in good faith42 and that funding is one of the key and critical components
that has really hurt the Paul First Nation's ability to express its concerns.43
90. The Paul First Nation acknowledged that TAMA Power has made many efforts to
consult and that it could see that there has been an interest in trying to work together. The
Paul First Nation stated that TAMA Power has people within its organization who certainly do
care a great deal about the condition of the Paul First Nation and have made big efforts. It added
that over the last two years, there certainly was regular interaction between TAMA Power,
TransAlta and the Paul First Nation.
91. However, certain members of the Paul First Nation stated that they did not consider the
open house held for them to be consultation, but simply an information session.44
92. The Paul First Nation indicated at the hearing that other factors affecting it had limited
its ability to fully participate in both consultation and the proceeding.45

Sundance 7 Power Plant TransAlta MidAmerican Partnership
16 • Decision 3183-D01-2015 (June 9, 2015)
6.5 Commission findings
93. Rule 007 states that a participant involvement program must be conducted before a
facility application is filed with the Commission. It is therefore a fundamental component of any
facility application.
94. The participant involvement program conducted for this project must meet the
requirements for consultation and notification set out in Rule 007. In assessing whether the
program was adequate, the Commission considers whether landowners and other stakeholders,
including First Nations and other aboriginal groups, were consulted prior to the filing of the
application. It also considers the applicant’s efforts to contact those persons or stakeholders,
including the refusal of landowners or other stakeholders to engage in consultation.
95. TAMA Power’s participant involvement program consisted of a mail out of project
information packages to all stakeholders and personal consultation with stakeholders located
within the project area, open houses, a project website, and ongoing efforts made to address
concerns as they arose. On this basis, the Commission finds that the participant involvement
program designed by TAMA Power met the requirements of Rule 007.
96. The Commission acknowledges that an effective consultation program may not resolve
all stakeholder concerns. There may be situations where individual stakeholders may feel that the
consultation effort, as it pertained to their interests specifically, was insufficient or superficial.
Furthermore, the perceptions of the applicant and some interveners about the quality and
effectiveness of the public consultation can sometimes be very different. This merely reflects the
fact that the parties do not agree and is not the fault of the applicant nor the interveners.
97. The Commission finds that the efforts made by TAMA Power to ensure that there were
multiple avenues for landowners and other stakeholders to obtain information or contact
TAMA Power satisfy the requirements of Rule 007.
98. The evidence demonstrated that TAMA Power provided means for potentially affected
stakeholders to make further inquiries, the open houses and publicly distributed information
contained clear contact information, and those individuals who were required to be consulted
personally also had contact information to reach TAMA Power if they had additional questions
or concerns. The Commission finds that TAMA Power demonstrated a willingness to meet with
stakeholders to discuss their concerns. In addition, TAMA Power appears to have been receptive
and responsive when dealing with new concerns raised by stakeholders after its application was
submitted to the Commission.
99. The Commission is satisfied that TAMA Power contacted, through personal
consultation, landowners and other stakeholders including First Nations and other aboriginal
groups, or that it made reasonable best efforts to contact them.
100. In Decision 2011-436, the Commission made the following comments with respect to
effective consultation under Rule 007:
… In the Commission’s view, effective consultation achieves three purposes. First, it
allows parties to understand the nature of a project. Second, it allows the applicant and
the intervener to identify areas of concern. Third, it provides a reasonable opportunity for
the parties to engage in meaningful dialogue and discussion with the goal of eliminating
Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 17
or mitigating to an acceptable degree the affected parties concerns about the project. If
done well, a consultation program will improve the application and help to resolve
disputes between the applicant and affected parties outside of the context of the hearing
room.46
101. The Commission finds that TAMA Power’s participant involvement program met the
three objectives described above with respect to the Cymbaluks and the Paul First Nation. The
Commission heard evidence of a long history of consultation with these parties dating back many
years, and a commitment to ongoing consultation. Although the Paul First Nation considered that
the open house held for its members was a presentation and not consultation, the Commission
finds that this open house, held at the request of the Paul First Nation, provided the Paul First
Nation members an opportunity to learn about the project and express their views.
102. The Commission understands that TAMA Power may not have been aware that the
Gunn Métis had concerns with the project until after the Gunn Métis emailed TAMA Power in
2014. In this regard, the Commission accepts TAMA Power’s evidence that it contacted the
Alberta Aboriginal Consultation Office for direction on which aboriginal groups it should
consult about the proposed power plant, and that the Gunn Métis was not listed as a potentially
affected aboriginal group. The Commission considers that the efforts made by TAMA Power to
identify aboriginal stakeholders were reasonable in the circumstances, and that it consulted with
the Paul First Nation and the Enoch Cree Nation as directed.
103. The Commission also heard evidence related to TAMA Power’s consultation with the
Gunn Métis, including the period of time before and after the Gunn Métis filed a statement of
intent to participate in this proceeding. There was email correspondence between the parties and
two meetings were held. The Commission is satisfied that TAMA Power attempted to
communicate the nature and details of the project and its potential impacts upon the Gunn Métis
in its meeting and various communications with the group’s representatives. It also
acknowledges the Gunn Métis’ concern that consultation did not continue between the time that
its members contacted senior management of TransAlta and the time the Gunn Métis was
granted standing; and that neither TAMA Power nor the Gunn Métis made efforts to attempt to
continue with consultation or contact each other during that time. In this regard, TAMA Power
could have better communicated its contact procedures and expectations, and perhaps reduced
the perception by the Gunn Métis that its request for a further follow-up meeting with
TAMA Power representatives had been ignored. Nevertheless, the Commission finds that
TAMA Power did make efforts to consider the specific concerns raised by the Gunn Métis and
that the Gunn Métis had adequate consultation from TAMA Power.
104. The Commission has considered the Gunn Métis’ request that construction not be
undertaken until the Gunn Métis and TAMA Power have jointly reported to the Commission that
they believe that the participant involvement program requirements have been fulfilled. Because
TAMA Power’s consultation with the Gunn Métis was found to be satisfactory and to have met
the requirements of Rule 007, the imposition of any further consultation requirements is
unnecessary should the project be approved.
105. The Commission denies the Gunn Métis’ request for capacity funding because under
Section 21 of the Alberta Utilities Commission Act, it may award costs as prescribed in its rules
46
Decision 2011-436, page 57, paragraph 283.
Sundance 7 Power Plant TransAlta MidAmerican Partnership
18 • Decision 3183-D01-2015 (June 9, 2015)
and no other funding. Rule 009: Rules on Local Intervener Costs stated that interveners may
apply to the Commission for a costs award and includes provisions related to requests for
advanced funding. Additionally, the Gunn Métis retained counsel and experts to assist it in
making its representations before the Commission on the application.
106. Accordingly, the Commission concludes that TAMA Power’s consultation and
participant involvement program met the regulatory requirements of Rule 007 and was adequate
in the circumstances.
7 Noise
107. Rule 012: Noise Control applies to noise from the construction and operation of electric
and natural gas utility facilities. Rule 007 requires an applicant to provide a noise impact
assessment (NIA) as part of a new power plant application. The purpose of Rule 012 is to ensure
that the noise from a proposed facility, measured cumulatively with noise from other nearby
energy-related facilities, will not exceed the permissible sound level.
108. TAMA Power filed two NIAs in support of the application. Golder Associates Ltd.
(Golder) was retained to prepare the NIAs and provide evidence on the project’s noise impacts.
109. The first NIA was dated and filed in April 2014 (the original NIA). A second NIA
prepared in response to the concerns of the Cymbaluks family (the updated NIA), was dated and
filed in April 2015. The updated NIA replaced the original one and was tested during the
hearing. In both the original and updated NIAs, Golder predicted that the project would comply
with the permissible sound levels of 50 dBA Leq daytime and 40 dBA Leq nighttime determined
in accordance with Rule 012.
110. Victor Young, a professional engineer with expertise in noise acoustics and vibrations
with Golder, conducted field measurements, performed noise emissions calculations, developed
the computer noise model, and authored the updated NIA for the project. Mr. Young testified at
the hearing regarding the noise reports, including the NIAs, prepared by Golder.
111. The Cymbaluks contested the validity of the NIAs on a number of grounds which
included sound source identification, predicted sound level and compliance determination, noise
control measures, TAMA Power’s input parameters in the model and standards used, and
applicable noise mitigation measures. The Cymbaluks retained James Farquharson of
FDI Acoustics Inc. (FDI Acoustics) to provide evidence with respect to noise, including both
NIAs submitted in support of the proposed power plant application.
7.1 Views of the applicant
112. In response to concerns from the Summer Village of Kapasiwin about increased noise,
TAMA Power retained Golder to prepare a report on the project’s potential noise impacts at that
location.
113. The report indicated that the proposed power plant was unlikely to affect the noise levels
for the Kapasiwin residents. Golder also explained that currently, the predicted noise levels in
Kapasiwin are well below the permissible sound levels in Rule 012 and any marginal increase in
the noise level from the project would not result in an exceedance of the permissible sound level.
Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 19
114. At the hearing, Mr. Young testified:
Our conclusion in the memorandum was that given the large distance between the
Sundance 7 project and the Summer Village of Kapasiwin, approximately 7.5 kilometres,
the project is unlikely to cause any perceptible changes in noise levels at the village
With respect -- or with regards to low-frequency noise, which was one of the concerns
raised by Kapasiwin, measurements previously conducted for the existing Keephills
facility suggest that there is no particular reason to expect that there will be any low-
frequency noise issue associated with the Sundance 7 plant.47
115. In response to questions from the Gunn Métis, Golder explained that Rule 012 does not
contain any provisions regarding the impacts of noise on wildlife. Mr. Young explained that the
Alberta Energy Regulator’s Directive 038: Noise Control, which is very similar to Rule 012 and
has the same sound level limits as Rule 012, states that the sound levels are designed to be
protective of wildlife.48 Mr. Young indicated that he has no specific experience assessing the
impacts of noise on wildlife.49
7.1.1 Original NIA
116. Golder stated that the original NIA was based upon the most up-to-date project design
and engineering information available in April 2014.
117. Two noise receptors were considered in the original NIA and were designated as R1 and
R2. Receptor R1 was identified as an occupied farmhouse, or the Cymbaluk family’s residence,
located in the southeast quarter of Section 10, Township 52, Range 4, west of the Fifth Meridian
and 1,160 metres from the center of the proposed power plant. Receptor R2 is a TransAlta-owned
farmhouse located in the southeast quarter of Section 11, Township 52, Range 4, west of the
Fifth Meridian and 1,420 metres from the centre of the proposed power plant.
118. The permissible sound levels were determined in accordance with Rule 012 for both
noise receptors and were 50 dBA Leq daytime and 40 dBA Leq nighttime. In Rule 012, the
daytime period is defined as the hours of 7 a.m. to 10 p.m. and the nighttime period is defined as
the hours of 10 p.m. to 7 a.m.
119. The predicted cumulative sound level, including the assumed ambient sound levels, was
compared to the permissible sound levels at receptors R1 and R2. The results were as follows:50

7.1.2 Updated NIA
120. TAMA Power explained that the project design had advanced considerably since
April 2014 when the original NIA was completed and that the updated NIA was submitted in
response to intervener concerns51 and was designed to replace the original NIA.
121. Golder explained that the updated NIA provided the most up-to-date design features of
the proposed power plant. It stated that the project design and engineering information used in
the updated NIA is near-final and represents the information that was current as of
March 24, 2015. Project design and engineering information used in the updated NIA was
provided by the major equipment supplier and by the potential engineering, procurement and
construction contractors for the project. TAMA Power stated that the updated NIA considered
two assessment cases: the baseline case and the application case for receptors R1 and R2
described above. The predicted results were as follows:52
Receptor Daytime baseline case (dBA)
Nighttime baseline case
(dBA)
Daytime application case (dBA)
Nighttime application case

Daytime / nighttime
permissible sound levels
(dBA Leq)
R1: 46 38 46 39 50/40
R2: 46 39 46 39 50/40
122. Golder stated that the noise emissions for the baseline case are similar to those used in
the original NIA. At the hearing, Mr. Young explained that some of the sources were broken
down further for the purposes of the updated NIA.
7.1.3 Updated NIA noise model and ground attenuation factor
123. TAMA Power used the computer noise model Predictor® Version 9.11 software to
predict the noise impact of the project. TAMA Power stated that the Predictor® Version 9.11
software was developed in accordance with the ISO 9613-253 standard (the ISO 9613 standard)
for the propagation of environmental noise and is one of two modelling standards referenced
explicitly in Rule 012. Golder pointed out that the noise model referenced by the Cymbaluks’
expert was not referenced in the ISO 9613 standard.
124. TAMA Power also stated that the Predictor® Version 9.11 software takes into account
noise attenuation related to meteorological conditions, ground cover and physical barriers.
125. In response to the Cymbaluks’ expert’s suggestion that a safety margin should be
implemented, Golder stated that the use of an explicit safety margin in NIAs is neither required
nor common.54 Golder explained that this is due to NIAs incorporating several factors, making
them inherently conservative.

Decision 3183-D01-2015 (June 9, 2015) • 21
126. The ground factors used in the Predictor® Version 9.11 software included the following
ground absorption factors:55
G = 0.0 for water and paved surfaces
G = 0.2 for compacted surfaces
G = 0.5 for gravel-covered surfaces
G = 0.8 for surrounding farm fields
G = 1.0 for porous ground
127. Golder stated the Predictor® Version 9.11 software accounts for attenuation due to
geometrical divergence, atmospheric absorption, ground effect and screening by barriers, and in
the case of ground effect, the updated NIA treated the ground of the surrounding farm fields
around the project using a ground attenuation factor of G = 0.8, which is considered more
reflective and less absorptive than the ground factor recommended by the ISO 9613 standard.
Golder submitted that this modelling of the ground tends to enhance propagation between the
project and receptors R1 and R2, and consequently overestimates the project’s noise impacts.
Other ground attenuation factors were used in the model for the appropriate ground type and
included G = 0.0 for water and paved surfaces, G= 0.2 for compacted surfaces and G= 0.5 for
gravel-covered surfaces.
128. In response to the Cymbaluks’ noise expert’s suggestion of a 0.5 ground factor, Golder
submitted that the ground factors used were sufficiently conservative and appropriate.56
7.1.4 Noise wall
129. TAMA Power explained that its modelling was premised on the inclusion of a noise
barrier or wall to reduce the proposed power plant’s noise emissions on the Cymbaluk family
and to achieve compliance with the permissible sound level. An L-shaped noise wall, designed to
reduce the noise level at the Cymbaluk family’s residence, would surround the south side and
east end of the proposed power plant’s cooling tower. Golder specified that the predictions in the
NIAs were dependent upon the inclusion of the noise wall.
130. TAMA Power stated that the noise wall’s dimensions had changed as a result of the
project design which was updated since the submission of the original NIA. The noise wall’s
dimensions as stated in the original NIA were 13 metres tall with a south wall length of
191.8 metres and an east wall length of 38 metres.57 At the hearing, TAMA Power confirmed that
the revised dimensions were 18.3 metres tall with a south wall length of 160 metres, and an east
wall length of 53 metres.58

22 • Decision 3183-D01-2015 (June 9, 2015)
7.1.5 Sound source identification
131. TAMA Power stated that the major sources of noise emanating from the proposed power
plant include:
the heat recovery steam generators exhaust stacks
the gas turbine air inlets
the noise breakout through the walls and roofs of the gas turbine building
the heat recovery steam generator building
the steam turbine building
the fuel gas compressor building
the noise breakout through building ventilation louvers
the building ventilation and exhaust fans
the cooling tower air inlets (including noise from falling water)
the cooling tower air outlets
the fuel gas compressor cooler units
the power transformers
the auxiliary transformers
132. The two gas turbine generators, two heat recovery steam generator units, one steam
generator and three fuel gas compressors are to be located inside buildings fitted with ventilation
louvers which will reduce noise emissions to the surrounding environment. The gas turbine air
inlets and the heat recovery steam generators exhausts will be fitted with silencers.
133. The proposed cross flow cooling tower would consist of 12 cells that would be installed
with fans that can operate in two modes.
134. The updated NIA stated that the noise rating of the three power transformers are
substantially lower than the default noise emissions specified by the relevant National Electrical
Manufacturers Association technical standard.
135. TAMA Power stated that because the project is near its final design, it does not have
sound power levels for all project components. However, Golder added that there was enough
information available to complete noise modelling because TAMA Power had received a noise
level guarantee for the sound contribution level of the proposed power plant.
136. TAMA Power stated that it is in negotiations to finalize the contract with an
engineering, procurement and construction contractor for construction of the project. There are
two candidates and both have agreed to provide a guarantee on the proposed power plant’s noise
emissions. This noise level guarantee is designed so that the cumulative sound level at R1 and
R2 would achieve compliance with the permissible sound levels.
137. At the hearing, Mr. Young explained that some of the project’s components have yet to
be finalized, and that sound power levels for these components (individual noise sources) were
derived using a back-calculation method from the overall noise guarantee provided for the
proposed power plant. In other words, Golder was able to derive sound power levels for some
power plant components from the overall noise guarantee. Mr. Young explained that these
derived individual sound power levels were used as inputs into its noise model when it prepared
the updated NIA. Mr. Young further testified that while this approach is uncommon, it is similar
Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 23
to other methods for deriving sound power levels from sound pressure levels, which is a common
industry practice.
138. TAMA Power also provided the breakdown of the sound power levels for the above
project components in response to an information request. At the hearing, it acknowledged that
some of its answers had changed as a result of design changes and provided an updated
information response. TAMA Power reiterated that the total sound contribution level of the
proposed power plant had not changed because of the design changes.
139. TAMA Power stated that the updated NIA made use of a number of conservative
assumptions that tend to overestimate the noise impact of the project, which provides an inherent
safety margin when comparing cumulative noise level predictions to actual sound level
measurements. Those conservative assumptions include the project cooling towers and the
electrical transformers operating in the loudest mode at all times, even though the cooling towers
can operate at a low speed and the electrical transformers can operate in a number of different
cooling modes when ambient temperatures are low and cooling is not required.
7.1.6 Existing energy-related facilities
140. Both NIAs contained an assessment of the sound levels of existing energy-related
facilities in the project area. TAMA Power explained that TransAlta owns and/or operates a
number of existing facilities in the area and that these were included in the model when
predicting the cumulative sound level for the project. Third party energy-related facilities in the
project area belong to Zargon Oil and Gas Ltd., New Star Energy Ltd., and ATCO Gas and
Pipelines Ltd.
141. The baseline case as modelled by Golder considered the noise contributions of existing
and approved energy-related facilities. These facilities typically fell into two categories:
(1) facilities own by TransAlta; and (2) facilities own by third parties.
142. The facilities owned by TransAlta included power generating facilities such as the
Sundance Generating Facility, the Keephills Generating Facility and the Highvale Coal Mine. To
determine the sound level contributions of each of the TransAlta facility operations, Golder used
the NIA for these facilities and supplemented this information with actual noise measurements.
In situations where information was missing, Golder identified the existing equipment and
estimated the noise emissions based on its professional experience using a combination of
vendor data for similar equipment and empirical formulae from the acoustics literature.
143. Golder submitted that it considered the data provided with respect to each of the
TransAlta owned facilities up-to-date and applicable for the purposes of the NIAs.
144. In addition, six third-party industrial developments operating within approximately
2.5 kilometres of the two noise receptors were identified and included in the updated NIA to
more fully characterize the cumulative noise environment.59

24 • Decision 3183-D01-2015 (June 9, 2015)
7.1.7 Low frequency noise
145. Golder modelled the potential for low frequency noise in both the updated and the
original NIAs. Rule 012 defines the low frequency noise range to be from 20 hertz (Hz) to
250 Hz. Golder calculated the dBC sound pressure value minus the dBA sound pressure value to
identify the potential for a low frequency noise condition. Golder added that this was completed
for both existing energy-related facilities and the proposed power plant and explained that, in
accordance with Rule 012, a low frequency noise condition may exist when the dBC minus dBA
value is equal to or greater than 20 dB and a clear tonal component exists between the
frequencies 20 and 250 Hz.60
146. The results of the application case, which included the addition of the Sundance 7 noise
contributions, showed that the difference between the dBC and dBA values was greater than
20 dB at receptor location R1 during both the daytime and nighttime periods. This indicated the
potential for low frequency noise.
147. Golder indicated that once the project commences operations, conducting near-field
source measurements at the project and a noise monitoring program could be conducted at the
potentially impacted receptor to identify the presence or absence of a low frequency noise issue.
148. In the event that a low frequency noise condition was definitively identified, the nature
of the mitigation measures implemented would depend on the specific sources responsible for
the low frequency noise.
7.1.8 Post-construction sound level monitoring
149. TAMA Power committed to completing a comprehensive sound level monitoring survey,
in accordance with Rule 012, at the residence of David, Philip and Ferne Cymbaluk once the
project is operational. Should the results of the comprehensive sound level monitoring indicate
non-compliance, TAMA Power would investigate the noise issue and resolve it.
150. TAMA Power testified at the hearing that it is aware that it must meet the permissible
sound level at R1, the Cymbaluk family’s residence, at all times.
7.2 Views of the Cymbaluks
151. The Cymbaluks were concerned that further development in the area would have the
potential for high frequency and low frequency noise. The Cymbaluk family stated it finds the
existing noise impacts to be unacceptable and non-compliant with noise directives and has had to
lodge noise complaints with industrial operators in the area, including TransAlta. The Cymbaluk
family expressed concerns with TransAlta’s noise complaint and investigation process, including
the adequacy and thoroughness of the noise complaint investigation procedures.
60
AUC Rule 012 defines the low frequency noise range to be from 20 Hz to 250 Hz. If a project’s dBC sound
pressure value is available, the Commission requires the applicant to calculate the dBC sound pressure value
minus the dBA sound pressure value to identify the potential for a low frequency noise condition. In accordance
with AUC Rule 012, a low frequency noise condition may exist when the dBC minus dBA value is equal to or
greater than 20 dB and a clear tonal component exists between the frequencies 20 to 250 Hz.
Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 25
7.2.1 Original NIA
152. As stated earlier, the Cymbaluks retained FDI Acoustics to review the original and the
updated NIAs as well as other noise-related information relating to the project. FDI Acoustics
took issue with the original NIA prepared by Golder in its report. The specific concerns primarily
related to modelling, ground factor, and the modelling of other energy-related facilities, which
are discussed below.
7.2.2 Updated NIA
153. The Cymbaluks also took issue with the updated NIA and requested that complete and
updated answers to the information they requested be provided.
154. FDI Acoustics recommended a safety margin for the predicted sound levels, a
recompletion of the NIA using a less optimistic ground absorption value, and a
post-commissioning comprehensive sound survey and near-field measurement assessment should
the project be approved.
155. Mr. Farquharson testified that if TAMA Power wanted to spend enough money to build
Sundance 7 quietly “there would be a method to do that”.61 However, the Cymbaluks questioned
whether TAMA Power was willing to build Sundance 7 quiet enough to be compliant with
Rule 012.62
7.2.3 Updated NIA noise model and ground attenuation factor
156. FDI Acoustics critiqued the noise model used by Golder. FDI Acoustics advocated the
use of the Environmental Noise Model (ENM) noise model which was developed by
RTA Technology Pty Ltd in 1986 and predicts noise levels from known noise sources at receptor
locations. FDI Acoustics formulated a modelling exercise to provide a comparison of how
ground attenuation is treated between the ISO 9613 standard using the Predictor® Version 9.11
noise model and the ENM noise model under similar modelling parameters.
157. FDI Acoustics explained that several project-specific factors contribute to whether a
noise model is conservative including the ground factor, the height of the sound source, and the
sound spectrum.
158. In the ENM noise model there are eleven available ground types from which to select
varying categories from a Type 1 for dry snow to a Type 11 for asphalt or water. Grass is
categorized as being Type 4, which is comparatively more conservative than how grass is
categorized in the ISO 9613 standard.
159. Also, given the height of the proposed power plant and the mid-frequency of the sound
emitted, the ENM noise model is more conservative compared to the ISO 9613 standard.
160. At the hearing, Mr. Farquharson gave evidence with respect to the limitation of the
ISO 9613 standard specifically in terms of wind and thermal inversion. He state that it lumped
wind, thermal inversion and multiple speeds of wind together so one could not specifically select

26 • Decision 3183-D01-2015 (June 9, 2015)
values. In contrast, the ENM noise model allows specific inputs for wind and temperature and is
more flexible in this area than the ISO model.63
161. Based on its critique of the noise model, FDI Acoustics also questioned the ground
factor used in the noise modelling, stating that the ground factor used by Golder was not the most
conservative.
162. FDI Acoustics stated that it considers the use of a 0.5 ground absorption value for the
vegetated lands of the model a more conservative approach, adding that the use of the 0.5 value
is based on experience and recommending that an NIA should reflect a possible complaint
margin.
7.2.4 Noise wall
163. The Cymbaluk family questioned whether the sound barrier wall proposed for the
project would provide effective noise mitigation at the David, Philip and Ferne Cymbaluk
residence. The family members argued that under certain weather conditions, the shadow zone of
noise barrier may not be in effect at their residence.64 The Cymbaluk family was also concerned
that the dimensions of the noise wall had changed.
7.2.5 Sound source identification
164. FDI Acoustics had several concerns with the project after reviewing the original NIA.
The project is based on an on-going project design. Although the proposed sound barrier wall for
the south and east sides of the cooling tower had changed in comparison to an earlier design, the
results had not been updated.
165. At the hearing, the Cymbaluks also criticized Golder for not having a final design of the
cooling tower at a prior stage of the project.
166. FDI Acoustics stated that it was not an expert in cooling tower design, but pointed out
that cooling tower suppliers are very reluctant to endorse the placement of any large structures
near the inlets of a cooling tower because it will completely block the natural airflow path into
the cooling tower on the south side. FDI Acoustics questioned whether TAMA Power secured
acceptance of the proposed barrier by the cooling tower supplier.
167. TAMA Power did not consider or provide a safety margin in respect of the predicted
results at both receptors. FDI Acoustics noted that the predicted sound level was at 40 dBA Leq
nighttime at receptor R1 under the original NIA and 39 dBA Leq in the updated NIA. More
specifically, FDI Acoustics suggested that because the project design may be preliminary, it
would be prudent to consider a design safety margin. A safety margin can be imposed as an
overall project contribution target or the safety margin can be placed on individual items based
on noise data quality, equipment sound emission ranges, historical predicted versus actual, noise
control measure performance levels and experience.

Decision 3183-D01-2015 (June 9, 2015) • 27
7.2.6 Existing energy-related facilities
168. FDI Acoustics also suggested a safety margin because there were many noise sources in
the area. Mr. Farquharson testified that “….we have an environment where we have a large
amount of the [noise] room that is available to AUC and Alberta Energy Regulator’s regulated
sources filled already”.65 These sources include power plants such as Keephills units 1 to 3 and
Sundance units 1 to 6.
169. The Cymbaluks took issue with Golder’s modelling of the existing energy-related
facilities in the area.
170. The Cymbaluks submitted that when considering whether the application is in the public
interest, the Commission should take note that the noise modelling in the original NIA did not
include all emissions sources and noise associated with the reclamation of other facilities in the
area. The NIA for the Keephills Coal Preparation Plant,66 which was used in the original NIA to
determine background levels, did not include contributions of noise from Keephills units 1 and
2.67 They requested that the project not be approved, or in the alternative, that the Commission
defer consideration of the TAMA Power application until TransAlta resolves the current noise
complaints with respect to TransAlta’s existing extensive operations in the area.
7.2.1 Summer Village of Kapasiwin
171. The Summer Village of Kapasiwin expressed concern with the addition of another noise
source in the area and that the project, if approved, could potentially contribute to unacceptable
levels of noise in the area.68 It submitted that the stack height of the proposed power plant is
approximately 166 feet above ground level elevation69 and that there is no potential for
attenuation of the sound emitted from the proposed power plant toward the Summer Village of
Kapasiwin.70
172. The Summer Village of Kapasiwin wanted to ensure that proper sound attenuation
equipment is included in the design of the project71 and also expressed concern with the potential
for low frequency noise as a result of the operation of the proposed power plant. It requested
independent sound monitoring upon completion of the proposed power plant and annually
afterwards.72
7.3 Views of the Gunn Métis
173. The Gunn Métis expressed concern about noise from construction and operation of the
proposed power plant. The Gunn Métis is concerned that noise in the area would impact animals
and cause wildlife to avoid the area, and that it could impact hunting.

28 • Decision 3183-D01-2015 (June 9, 2015)
7.4 Commission findings
174. Rule 012 requires the use of computer models that meet accepted protocols and
international standards for predicting a project’s cumulative sound level and identifies the
ISO 9613 standard as one such international standard. The Commission finds that the noise
model used for the project followed the ISO 9613 standard and complies with the requirements
of Rule 012.
175. The Commission acknowledges the view of FDI Acoustics that the ground attenuation
input would result in a more conservative (higher) predicted sound level. However, the
Commission finds that the ground attenuation factor used by Golder in the updated NIA follows
the guidance described in the ISO 9613 standard and is acceptable for use in this project.
176. The Commission understands that for sound power levels of individual project
components, some of the values used in preparing the updated NIA were obtained via a
back-calculation from the noise level guarantee. The Commission has considered the overall
approach used by Golder in modelling the sound level contributions from the proposed power
plant and finds Golder’s approach to be reasonable given the stage of the proposed power plant
design.
177. One of the primary issues raised by the interveners was that the modelling did not
adequately predict the noise levels of the existing energy-related facilities in the area. The
Commission understands that the operations of the existing TransAlta facilities and third party
facilities may impact the cumulative sound level at receptors R1 and R2 and that Golder used the
predicted noise contributions from third party NIAs in preparing both the original and updated
NIAs. The Commission has reviewed the submissions and the third party NIAs that were
incorporated into the updated NIA and finds the use of these data values to be acceptable.
178. While all noise models have a level of uncertainty, Rule 012 does not require an applicant
to take this into account in an NIA when determining whether a project meets the permissible
sound level. TAMA Power’s compliance with the permissible sound level is of paramount
importance at all receptors, including the Cymbaluk family’s residence. Even if the modelling
proves to be inaccurate, the project must be constructed and operated such that it will comply
with the permissible sound level. Compliance can be determined by a post-construction
comprehensive sound level survey. As such, should the Commission approve the project,
approval would be subject to the following condition:
TAMA Power shall conduct a comprehensive sound level survey at receptor R1, the
Cymbaluk family's residence, within one year of Sundance 7’s operation and file the
results with the Commission.
179. Having regard to the foregoing, the Commission finds that the applicant incorporated
reasonable modelling assumptions and protocols when preparing the updated NIA and upward or
downward adjustments to the predicted sound levels are not required because of the modelling
and standards used. The Commission concludes that the results of the updated NIA were
consistent with the requirements of Rule 012.
180. The Cymbaluk family’s outstanding noise complaints are the subject of a separate
proceeding before the Commission, consequently it is unnecessary to make any finding on this
issue in this proceeding.
Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 29
181. The Commission has also reviewed the material presented for the project’s potential to
increase the cumulative sound level in the Summer Village of Kapasiwin. FDI Acoustics did not
contest the results obtained by Golder. The Commission therefore accepts Golder’s predictions
that the proposed power plant will not cause an exceedance of the permissible sound level at that
location.
182. The issue of noise impacts to wildlife was also raised by the Gunn Métis. However,
Rule 012 applies only to residences, not to wildlife and there is insufficient evidence before
the Commission to determine whether the project’s predicted sound emissions would affect
wildlife in the area. The Commission finds that the Gunn Métis’ concerns were unsubstantiated
but nonetheless accepts Golder’s submission that the Alberta Energy Regulator’s
Directive 038: Noise Control indicates that the permissible sound levels would be protective of
animals.
8 Vegetation and wildlife
8.1 Views of the applicant
183. TAMA Power retained Golder to prepare an environmental report, conduct fieldwork
and give evidence on the project’s potential impact on vegetation and wildlife.
184. TAMA Power explained that the project is proposed to be on private land which has
been owned by TransAlta for many years.73 The project site has historically been used primarily
(80 per cent) for agricultural operations and only contains remnant native woodlots, shrubs and
wetlands. On this basis, Golder indicated that a large impact on vegetation and wildlife was not
expected.
185. Golder conducted baseline environmental studies in support of TAMA Power’s
application to the Commission and ESRD. These studies contained two components, desktop and
field work, designed to identify the presence of rare plants on the project site and the surrounding
area. TAMA Power stated that the field work was conducted in 2010 and 2014.74
186. TAMA Power noted that the scope of the environmental assessment required for the
project is established by provincial and federal regulators on a project-specific basis,
commensurate with the anticipated environmental effects of the project. Generally, natural
gas-fired combined-cycle power plants such as Sundance 7 are regarded as having relatively low
environmental impacts when compared to other types of energy projects.
187. TAMA Power submitted a project summary to ESRD at the provincial level. It was
advised by ESRD in March 2014 that an environmental impact assessment report under the
Environmental Protection and Enhancement Act was not required for Sundance 7.75
188. TAMA Power submitted a project description to the Canadian Environmental
Assessment Agency and was advised in August 2014,76 that the environmental effects of

the project were well understood, that the project was not likely to cause adverse
environmental effects and that an environmental assessment was not required under the
Canadian Environmental Assessment Act, 2012.77
189. Golder conducted a search of the Alberta Conservation Information Management
System, which revealed no provincially listed plant species or communities on, or within
one kilometre of, the project site. The absence of rare plants was confirmed during a rare plant
survey conducted on the site in 201078 and TAMA Power submitted that the impact on vegetation
from Sundance 7 would be very minor.79
190. In addressing the Gunn Métis’ concern about the existence of ethnobotanically
important species, Golder indicated that gooseberries, Saskatoon berries, birch, fragaria,
strawberries, raspberries, rose and poplar were identified on the project site:80
191. Golder stated that no sweetgrass was identified on the project site during the course of
its field work.81
192. TAMA Power further stated that given the paucity of wildlife habitat on the project site,
the design of the project, and the implementation of mitigation measures described in the
application, the effects of the project on wildlife, including migratory birds and wildlife habitat
were expected to be negligible.82
193. In response to the Gunn Métis’ concern relating to fragmentation, Golder submitted that
based on its experience it did not expect that the proposed power plant would affect, plants
outside of the project site.83
8.2 Views of the Gunn Métis
194. Karen Kubiski submitted a written report on the ethnobotanical effects of Sundance 7 on
behalf of Gunn Métis. Ms. Kubiski undertook a review of the research on the effects of
fragmentation and habitat loss, which suggested the use of no greater than a 20 per cent loss of
native plant communities as an acceptable level of human disturbance. She submitted that higher
rates of loss of plant communities lead to many other ecological changes across the landscape.84
She added that in order to conserve or sustain a species of value, it would be most important to
reduce the loss of plant communities to less than 20 per cent and to ensure restoration of plant
community disturbance.
195. Ms. Kubiski submitted that sweetgrass is a sensitive species, exhibiting low
reproduction and distribution rates, that does not grow in disturbed areas. If habitat is lost where
Sundance 7 is built, the additional fragmentation could have cascading effects upon the

sweetgrass species as a whole in the watershed by making it more difficult for the remaining
patches of sweetgrass to reproduce and colonize.85
196. Ms. Kubiski asserted that the availability of ethnobotanical species on the project site or
in the watershed was not considered by Golder in its vegetation work.
197. Ms. Kubiski also criticized the vegetation work conducted by Golder, stating
specifically that Golder’s survey for noxious weeds failed to identify tansy, which is easily
identifiable on the project site even in wintertime conditions.86
198. Ms. Kubiski opined that the Lake Wabamun watershed cannot likely take further
unmitigated disturbance and continue to meet the ethnobotanical harvesting needs of the
Gunn Métis. For example, the emission of polycyclic aromatic hydrocarbons and nitrous oxide
(NOx) as well as removal of plant communities produce long-term and short-term effects on
vegetation surrounding the project.87
199. The NOx emitted by the project could cause serious damage or death to plants if it is
emitted in gaseous form or if it contributes to acid rain. Her report further outlined concerns that
in constructing the project, wetlands, which are valued and used by the Gunn Métis, and remnant
native woodlots, which support many ethnobotanical species,88 would have to be removed from
the general area.
200. Ms. Kubiski described how, in addition to considering species at risk, endangered or
tracked, an effective ecosystem management must consider conserving a diversity of intact
native plant community types at the landscape level.89
201. The Gunn Métis requested that the construction and operation of Sundance 7 be
approved with the condition that a special-use vegetation survey of the Lake Wabamun
watershed be undertaken and the results and recommendations of that study be supplied to the
Commission six months prior to construction of the project.90 It also requested the following
additional conditions if the power plant were to be approved:
That a monitoring program of populations of sweetgrass and possibly other threatened
ethnobotanical species within the Wabamun Lake Watershed be put in place, where an
ecologist of the Gunn Métis's choosing could train its members to engage in that
monitoring and apply their traditional knowledge;
A native plant nursery be considered to grow plants used for medicines, food, and other
purposes that will be planted outside on areas disturbed by TransAlta.91
202. Edward Adams testified at the hearing that the area immediately around Lake Wabamun
was some of the Paul First Nation’s favourite hunting grounds and where members of the
Paul First Nation gather food, berries and medicines. He expressed concerns about pollution

from the project impacting fish, small fur-bearing animals, and medicinal plants along
Lake Wabamun.92
203. Lloyd Saulteaux testified that his family lives near Lake Wabamun and that the area
around the lake had been their hunting and trapping grounds. Mr. Saulteaux further stated that
his main concern regarding the project was that it may affect the way in which the members of
the Paul First Nation live off the land.93
8.3 Commission findings
204. TAMA Power’s evidence indicated that the project is located on land that is used
primarily for agriculture and that is interspersed with remnant native woodlots, shrubs and
wetlands. David Cymbaluk testified that when he leased the project site, he farmed over some of
the smaller wetlands present on the site.94 Golder’s rare plant surveys conducted in 2010 and
2014 identified certain plants such as raspberries and strawberries, but did not identify any
sweetgrass.95
205. Furthermore, the results of Golder’s environmental baseline reports indicated that the
potential environmental impacts were of a limited nature. This view was supported by the
opinion of ESRD and the Canadian Environmental Assessment Agency when both agencies
found that no additional environmental impact assessments were needed for the proposed power
plant.
206. The Commission finds that the nature and extent of the environmental reports and the
field work conducted by TAMA Power were adequate in the circumstances. Due to the primarily
agricultural use of the project site, the Commission is not persuaded that a study of
ethnobotanical plants on the project site is required because the evidence before it is that adverse
effects to vegetation will be limited.
207. Ms. Kubiski’s concern with the fragmentation of ethnobotanical species was general in
nature, given the footprint and the current use of the project site. In this regard, the Commission
accepts Golder’s evidence that the construction and operation of the proposed power plant will
not impact plants and vegetation outside of the project site. Furthermore, the evidence of the
presence of ethnologically important species on the project site that would be disturbed as a
result of construction or the siting of the project’s permanent facilities was limited to species that
were available in the area. The Commission therefore finds that there is insufficient evidence
before it to conclude that the Gunn Métis’ members’ ability to harvest traditional plants is likely
to be impacted by fragmentation resulting from the project or by the construction and operation
of the proposed power plant.
208. The Commission finds that, based on the surveys conducted and TAMA Power’s
commitment to conduct further wildlife surveys prior construction, the project will have a
minimal impact on wildlife and wildlife habitat.

209. In light of the findings above, the additional environmental studies and field work
requested by the Gunn Métis are not necessary should the project be approved.
9 Waterbodies
9.1 Views of the applicant
210. Sundance 7 will use water from the existing Sundance industrial cooling pond and will
neither draw from nor discharge into Lake Wabamun. TAMA Power stated that water for the
Sundance industrial cooling pond will continue to be withdrawn from and returned to the
North Saskatchewan River under an existing Environmental Protection and Enhancement Act
approval which was granted by ESRD.96
211. According to the applicant’s evidence, Sundance 7 is designed so it will not change the
temperature of the water returning to the Sundance industrial cooling pond and therefore there
will be no change in the temperature of the water that will be returned to the North Saskatchewan
River.97
212. While there could be small changes in water quality in the North Saskatchewan River
during low-flow events due to the additional water diversion for Sundance 7, there would be no
changes in water quality exceedances compared to baseline or current conditions. TAMA Power
submitted that the overall effect of Sundance 7 on water quality in the North Saskatchewan River
is expected to be minimal and that the testimony on the historical impacts of the Wabamun
coal-fired power plant to water quality in Lake Wabamun was not relevant to Sundance 7.98
213. A wetland impact assessment conducted by Golder showed that the project would
potentially impact 12 Class 1 ephemeral wetlands totalling 0.79 hectares. TAMA Power reported
that these wetlands do not require any compensation under Alberta’s wetlands policy.99 The
project would impact one Class 2 temporary wetland totalling 0.11 hectares and one Class 3
wetland totalling 0.29 hectares, for which it would be providing compensation of 0.4 hectares of
Class 2 and Class 3 wetlands pursuant to Alberta’s wetlands policy. The wetland compensation
would be at a 3 to 1 ratio, and executed by Ducks Unlimited.100 During the hearing,
TAMA Power indicated that, while Ducks Unlimited cannot guarantee that it would adopt the
recommendations of the Gunn Métis on wetland compensation, it is willing to meet with the
Gunn Métis to discuss their recommendations. TAMA Power is committed to meeting with
Ducks Unlimited and the Gunn Métis to facilitate those discussions.101

planning to do and that no parties knew if potable water could be obtained from the aquifers.102
215. The Summer Village of Kapasiwin also expressed concern about the proposed power
plant’s impacts on Lake Wabamun.
9.3 Views of the Gunn Métis
216. The Gunn Métis submitted that although Dr. Robinson, on behalf of Golder,
indicated that the temperature of water from the Sundance industrial cooling pond into the
North Saskatchewan River will not change, TAMA Power did not address the impacts of
increased volume of warm water going into an already compromised river, where the fish is at
significant risk. The Gunn Métis further submitted that TAMA Power has not dealt with this
impact in the context of a lower overall flow and the increased volume taken out of the
North Saskatchewan River to support Sundance 7.103
217. The Gunn Métis added that there had been no analysis of what the increased withdrawal
and warm processed water flowing back into the North Saskatchewan River will mean for the
health of the river and the ability of the Gunn Métis to exercise its harvesting and other
traditional activities. The Gunn Métis indicated that TAMA Power did not engage in any
analysis of the current level of impact to the North Saskatchewan River, what is needed to
maintain an ecological base flow or in-stream flow needs, and the requirements to maintain the
subsistence needs of the Gunn Métis community.104
218. In regard to wetland compensation, the Gunn Métis stated that it must be meaningfully
engaged in the development of the wetland compensation offset. The Gunn Métis requested,
among other things, that the following elements be incorporated into a wetlands compensation
program:
wetland protection in an area convenient for the Lac Ste. Anne Métis harvesters; and
if there is development of replacement wetlands, the project be overseen by the Gunn
Métis, incorporate ethnobotanical species and include guidance from an ecologist of its
choosing.
219. It also requested a monitoring program to measure the health of the North Saskatchewan
River. The Gunn Métis is concerned with the current condition of Lake Wabamun and requested
that the Commission order TAMA Power to work with the Gunn Métis, prior to operation of the
plant, to undertake a study of what measures are required to restore Lake Wabamun to a healthy
state.105
9.4 Views of the Paul First Nation

power plant, stating that the water has become polluted and that they are no longer able to drink
or cook with the water, or eat the fish.
221. Lloyd Saulteaux asserted that since the Wabamun power plant had been constructed, it
had negatively impacted the fish as a result of warm water being put back into Lake Wabamun,
and that the lake was polluted.
9.5 Commission findings
222. The Commission accepts TAMA Power’s submission that water withdrawals for the
project would be from the existing Sundance industrial cooling pond, and be within the current
Environmental Protection and Enhancement Act approval limits to divert and return water.
223. With respect to the Gunn Métis’ suggestion that TAMA Power did not adequately
evaluate the effects of withdrawal and return of water to the North Saskatchewan River, the
Commission has taken into consideration that the withdrawals are within the limits imposed
under the current Environmental Protection and Enhancement Act approval and that ESRD
oversees the potential environmental effects associated with its approvals. The Commission also
heard evidence that members of the Gunn Métis continue to fish in the river and was not offered
any persuasive evidence that the fish may be affected by the incremental difference in the water
withdrawn or returned to the North Saskatchewan River. The Commission is therefore satisfied
that any adverse effects to the North Saskatchewan River would be minimal.
224. The Commission accepts TAMA Power’s assertion that the water withdrawal and waste
water return would not affect water quality or fish in the North Saskatchewan River. As such, the
Commission finds any further requirement to monitor the North Saskatchewan River
unnecessary should it approve the project.
225. The Gunn Métis also requested that the Commission order TAMA Power to undertake a
study to identify measures required to restore Lake Wabamun. The Commission denies this
request because no water will be taken or returned to Lake Wabamun for purposes of the
proposed power plant. Based on the evidence submitted, the Commission finds that the proposed
power plant will not have measureable impacts on Lake Wabamun.
226. The Cymbaluk family also took issue with the lack of clarity on groundwater
withdrawal by TAMA Power for potable water. In this regard, the Commission understands that
TAMA Power would have to obtain an Environmental Protection and Enhancement Act
approval to drill and operate a groundwater well. Further, TAMA Power would only use the
wells for potable water and all service water would be withdrawn from the Sundance industrial
cooling pond.
227. Based on the above, the Commission is therefore satisfied that the proposed power plant
would have minimal impacts on the North Saskatchewan River and groundwater.
228. The Commission considers that the project would have minimal impact on wetlands.
David Cymbaluk testified that he farmed over some of the smaller wetlands and TAMA Power’s
evidence is that the project would impact one Class 2 and one Class 3 wetland totalling
0.29 hectares. The Commission finds that the effects to wetlands can be effectively mitigated
with the implementation of the proposed wetland compensation. TAMA Power has also
committed to facilitating a meeting between Ducks Unlimited and the Gunn Métis to discuss
Sundance 7 Power Plant TransAlta MidAmerican Partnership
36 • Decision 3183-D01-2015 (June 9, 2015)
and, where possible, implement the Gunn Métis’ recommendations regarding wetland
compensation. Because the Commission has found that the effects on wetlands can be effectively
mitigated, no further requirements are necessary to protect wetlands as suggested by the
Gunn Métis.
10 Air emissions
229. TAMA Power retained Golder to provide evidence on air quality and filed an air quality
assessment.106
230. The Gunn Métis retained the Pembina Institute to evaluate the air quality assessment
conducted by Golder and submitted a report107 on the cumulative air quality impacts of Sundance
7. At the hearing, Andrew Read, one of the authors of the report, gave testimony on behalf of the
Gunn Métis.
231. In its rebuttal evidence to the Pembina Institute air quality report, TAMA Power
submitted a report written by Golder.108 Chris Madland and Dr. James Wilkinson, both of Golder,
testified at the hearing.
10.1 Government objectives standards on air quality
232. Alberta Environment and Sustainable Resource Development sets the Alberta Ambient
Air Quality Objectives which are used to evaluate the quality of the atmospheric environment,
evaluate development proposals and to assess compliance near major industrial air emission
sources. The Alberta Ambient Air Quality Objectives state the following objectives with respect
to ambient air quality concentrations:
Alberta Ambient Air Quality Objectives
Parameter Concentration (µg/m3)
Carbon monoxide (CO) 1 hour average 15,000
CO 8 hour average 6000
Nitrogen Dioxide (NO2) 1 hour average 300
NO2 Annual average 45
PM2.5 24 hour average 30
Sulphur Dioxide (SO2) 1 hour average 450
SO2 24 hours average 125
SO2 30 day average 30

Quality Standards (which will be discussed below) for fine particulate matter (fine particulate
matter or PM2.5) of 30 micrograms per cubic metre (g/m3).

Ambient Air Quality Standards since Alberta adopted the standard specified above. The current
Canadian Ambient Air Quality Standards for fine particulate matter are as follows:

PM2.5 24 hour average 28 27
PM2.5 annual average 10.0 8.8
235. Alberta Environment and Sustainable Resource Development, industry and other
stakeholders have also created an air emission management framework. The Alberta Air
Emission Standards for Electricity Generation, developed in accordance with that framework,
establishes facility-specific air emission limits which restricts the mass of NOx emissions
permitted in relation to the electricity generated.
Alberta Air Emission Standards for Electricity Generation New natural gas generating units111
Electrical Generating Power Capacity of the Plant Limit
Zero to 20 MW 0.6 kg/MWHoutput for each new generating unit

236. According to TAMA Power, Sundance 7 is a natural gas-fired power plant with low
emissions that would result in improved air quality because it is intended to replace the coal-fired
generating power plants currently operating in the area. The project includes a selective catalytic
reduction system designed to reduce emissions that is required by ESRD.
237. Golder completed a comparison of the existing or baseline emissions, project-only
emissions, and the application case, which included the predicted emissions from Sundance 7 in
addition to the baseline emissions. The air quality assessment considered the effect of the
project’s emissions under routine and non-routine operating scenarios in combination with the
emissions from existing and approved regional sources.
238. When completing the modelling, the CALPUFF112 air quality model was run in 3-D
mode to predict the maximum ground level concentrations for NOx, CO, fine particulate matter,
and ammonia (NH3) which were then compared to the Alberta Ambient Air Quality Objectives

to assess compliance. Golder reported that the modelling was conducted in accordance with the
Alberta Air Quality Model Guidelines.113
239. Golder reported that because project emissions would result in a minimal increase in the
ground level concentrations of NO2, PM2.5, and NH3, all would be below the Alberta Ambient
Air Quality Objectives for the proposed power plant’s normal operations.114 While no change in
ground level CO concentrations was predicted when the proposed power plant would be
operating at its full load, one exceedance per year, of the eight-hour Alberta Ambient Air Quality
Objective for CO, was predicted under the proposed power plant’s idling load operating
conditions.
240. With respect to fine particulate matter 24-hour average, Golder predicted two
occurrences per year above the Alberta Ambient Air Quality Objectives as a result of the
operation of Sundance 7, which TAMA Power asserted is consistent with the baseline case.
TAMA Power stated that because these occurrences are present in both the baseline and
application cases, the operation of Sundance 7 would not result in any additional exceedances of
the Alberta Ambient Air Quality Objectives.115 Golder attributed the PM2.5 exceedances of
24-hour Alberta Ambient Air Quality Objectives to forest fires and mining operations in the
area.116
241. Golder responded to concerns raised by the Gunn Métis that the air quality assessment
did not evaluate the potential for air emissions from the Wabamun/Genesee area to impact air
quality in Edmonton. Golder explained that the air quality monitoring stations were selected
based upon the Alberta Air Quality Management Guidelines, and that the predicted
concentrations of NOx, both the one-hour and the annual average, would be below 25 per cent of
the Alberta Ambient Air Quality Objectives west of Stony Plain, Alberta.117 TAMA Power
submitted that there was no evidence on the record of the proceeding that emissions from
Sundance 7 would have any meaningful impact on the air quality in Edmonton.118
242. Golder cited additional reference documents in response to the Gunn Métis’ concern that
insufficient information was provided to demonstrate that the exceedances of the Alberta
Ambient Air Quality Objectives were related to forest fires. No exceedances of the Alberta
Ambient Air Quality Objectives for PM2.5 occurred during 2008 and 2009. While exceedances
occurred in 2010, 2011 and 2012, the exceedances were attributed to forest fires by published
sources.
243. TAMA Power also addressed the Gunn Métis’ concerns with PM2.5, stating that the
secondary formation of PM2.5 was included in its modelling. Golder confirmed that Sundance 7
would comply with current and future Alberta Source Emission Standards.
244. To address the Gunn Métis’ concern that the air modelling did not assess air quality in
the Edmonton region, Golder indicated that the prevailing wind in the project area was from the

northwest – not toward the Edmonton region. NO2 concentrations are higher near the
Wabamun-Genesee area, decrease in a easterly direction, and then begin to rise again near
Edmonton. The highest concentrations of NO2 were found downwind of the predominate wind
direction, not toward Edmonton. Golder concluded that this pattern of ambient air concentrations
suggested that there was not substantial overlap of the resulting NO2 concentrations from these
two air emission sources.
245. Golder disagreed with the Gunn Métis’ assertion that a report published by the
Government of Alberta has attributed elevated PM2.5 levels in the city of Edmonton to emissions
from power generation in the Lake Wabamun area. Golder indicated that, contrary to the
submission of the Gunn Métis, the Government of Alberta report did not conclusively identify
any source of the elevated PM2.5 in the Edmonton region but vehicular emissions were
specifically identified as a likely cause.
246. TAMA Power retained Intrinsik Environmental Sciences Inc. (Intrinsik) to respond to
the evidence of the Gunn Métis. Intrinsik119 indicated that the Powers and Genesee air
monitoring stations in the area had been recording PM2.5 data for over 10 years. The results of
Intrinsik’s analysis of the concentration levels between 2006 and 2009 showed that the

Edmonton (8.7 µm/m3) and Calgary (8.3 µg/m
3) during the same time period, and well below the
Canadian Ambient Air Quality Standards.
Views of the Cymbaluks
247. The Cymbaluk family expressed concerns about the proposed power plant’s
contributions to dust, air contaminants, pollution and air quality impacts.120
248. The Summer Village of Kapasiwin submitted concerns about the operation of
Sundance 7 resulting in additional emissions to the airshed. It acknowledged that
TAMA Power’s information shows there will likely be a net reduction of NOx emissions when
Sundance 1 and 2 are decommissioned. It stated that it is probable that additional units will be
added to Sundance 7 and that this will result in increased air emissions, especially NOx, which
will continue to affect residents in the regional airshed, including those in the Summer Village of
Kapasiwin.
249. The Summer Village of Kapasiwin added the importance, to it and to its ratepayers, of
decommissioning the existing coal-fired power plants in accordance to the timeline predicted by
TAMA Power. It further recommended that an appropriate condition be implemented to this
effect should the Commission approve the proposed power plant.
10.3 Views of the Gunn Métis
250. The Gunn Métis is concerned with the current and future levels of air pollution. The
Gunn Métis indicated that it is supported by TAMA Power’s air quality assessments as well as a
recent technical investigation by the Government of Alberta, which both showed an exceedance
of the Alberta Ambient Air quality Objectives in relation to PM2.5. The Gunn Métis asserted that

Sundance 7 will add fine particulate matter to an already overburdened airshed.121 It further
submitted that ambient concentrations of fine particulate matter are also exceeded in Edmonton
and the Government of Alberta has identified electricity generation at Lake Wabamun as a
contributor to the problem.122
251. Mr. Read of the Pembina Institute submitted that the project is located within the
Capital Region Airshed Zone which has been experiencing exceedances of air contaminants;
specifically, exceedances of fine particulate matter. He reported that there is considerable
evidence that the electricity generation facilities in the region are contributing to these
exceedances. He stated that at lower emissions intensities, new combined-cycle generation in the
Wabamun area will contribute significant additional NOx emissions, because of the quantity of
new generation planned for the region.123
252. Sundance 7 is also located within the West Central Airshed Society Airshed Zone,
which contains seven continuous monitoring stations located within a 50-kilometre radius of the
project. Mr. Read indicated that although TAMA Power’s application shows that these seven
stations are representative of the air quality near the project, monitoring stations located more
than 50 kilometres from the project were not considered. Mr. Read reported that the seven
monitoring stations that were considered have all experienced PM2.5 exceedances in recent
years.124
253. Mr. Read did not accept Golder’s conclusion that forest fires were a likely cause of some
of the elevated readings of PM2.5. He stated that no significant evidence of the contribution from
either forest fires versus the electric generation facilities was provided. He indicated that Alberta
requires all industrial facilities be designed and operated to adhere to Alberta’s Ambient Air
Quality Objectives, even during unique weather systems or when other pollution sources, such as
forest fires, arise.125
254. Mr. Read submitted that there have been PM2.5 exceedances at three monitoring stations
in Edmonton. He reported there have also been less severe exceedances at monitoring stations in
the West Central Airshed Society, near the existing coal power plants and the project. He
indicated that these exceedances have occurred under standards that are less stringent than the
new standards in place for 2015. He asserted that if air quality does not improve dramatically, the
implementation of more stringent ambient air quality standards may continue to result in
exceedances even if minor air quality improvements are made.126
255. The Gunn Métis contended that TAMA Power had not provided evidence that credibly
contradicted the findings of the Government of Alberta and the Pembina Institute.127 Golder used
CALPUFF to conduct its air quality modelling which the Alberta Air Quality Modelling

Guidelines cite as a reliable regulatory model that can be used to predict the transport of
emissions over distances of one to 200 kilometres. Therefore, there was no technological barrier
to TAMA Power providing better information to the Commission regarding the dispersion of
PM2.5 associated with Sundance 7.128
256. The Gunn Métis submitted that continuous air quality monitoring at several local
stations was incomplete and TAMA Power had not identified the potential local impacts to air
quality.129 Further, there was no ambient air monitoring station west of Stony Plain to measure
substances of concern to the Gunn Métis. The Gunn Métis suggested that full monitoring in these
locations is important to understand the potential air quality impacts to a large proportion of
Gunn Métis community members.130
257. The Gunn Métis submitted that more data would be required to understand local air
impacts on its community. It requested that the Commission require TAMA Power to contribute
financially to support continuous monitoring of substances at existing air quality monitoring
stations, and to create a new monitoring station west of Stony Plain to measure all parameters in
advance of the operation of Sundance 7.131
10.4 Commission findings
258. It is the evidence of TAMA Power that air quality will be addressed through the design
of the proposed power plant and the commitments made in the application to implement the
proposed mitigation measures, such as the selective catalytic reduction system.
259. The Commission understands that the Alberta Ambient Air Quality Objectives are
regional goals for air quality that may be affected by a variety of regulated and non-regulated
emission sources. Golder’s evidence demonstrated that, with the exception of fine particulate
matter, air emissions from the project alone are predicted to be lower than the Alberta Ambient
Air Quality Objectives and that the incremental increase in NO2, CO and PM2.5 concentrations
will be minimal during normal operations. The Commission notes Golder’s prediction that there
may be one exceedance per year of the eight-hour CO standard when the proposed power plant is
idling. However, there will be no increase in the number of exceedances of the 24-hour Alberta
Ambient Air Quality Objectives for PM2.5 relative to current (baseline) conditions.
260. Gunn Métis witnesses gave evidence regarding air quality concerns in the Edmonton
area. The Gunn Métis argued in this regard that the scope of the air quality modelling conducted
by Golder was too limited in scope and should have further considered the project’s effects on
the air quality in Edmonton and the Capital Region. Because the boundaries of the air modelling
study were consistent with the methodology specified by ESRD, the Commission finds that no
additional modelling of air quality will be required if the project is approved.
261. The Commission finds that the incremental difference in air quality due to the project
will be minimal, and likely temporary. Assuming there are no other changes in emissions, overall
ambient concentrations of nitrous oxides, carbon monoxide and fine particulate matter are
expected to decrease upon the retirement of existing coal-fired power plant in the vicinity

because the project utilizes natural gas combined-cycle technology. Furthermore the
Commission has regard for ESRD’s oversight in establishing air emission standards.
262. The Commission finds that the Gunn Métis’ submission that the air quality monitoring
network is not adequate and should be supplemented was not supported by the evidence on the
record.
263. Based on all of the above, and given the nature of the proposed power plant and the
technology used the Commission finds that the project’s impact on air quality will be minimal.
264. The Commission has considered the concerns raised about the retirement of existing
facilities or generation facilities proposed in the future and impacts on air quality. However, the
current framework established by the Hydro and Electric Energy Act states clearly that the
Commission is to consider each application for a power plant individually.
11 Health
265. The Gunn Métis stated its concerns about the health effects associated with its members’
proximity to power plants, which related primarily to the health effects of fine particulate matter
and NO2 exposure. The Gunn Métis hired Dr. Joseph Vipond to provide evidence of the health
effects of air emissions. It was the evidence of Dr. Vipond that the project would result in health
effects for both nearby residents and those living in the broader Capital Region.
266. TAMA Power retained Intrinsik to provide reply evidence on the issue of the potential
health effects of the project and to respond to Dr. Vipond’s report. Intrinsik’s report indicated
that if actual levels are consistent with the levels predicted in the air modelling conducted by
Golder, the emissions from the project would not result in health effects.
267. TAMA Power also retained Dr. Don Davies, of Intrinsik, who testified about the health
effects from air emissions at the hearing.
11.1 Standards
268. The Canadian Ambient Air Quality Standards, referenced above, are health-based air
quality limits for pollutant concentrations in outdoor air. Under the Air Quality Management
System, Environment Canada and Health Canada established air quality standards for PM2.5 and
ozone, amongst other air quality parameters.
269. On May 13, 2013, new Canadian Ambient Air Quality Standards for PM2.5 were issued.
The new standards provide more stringent limits for outdoor air quality in Canada starting in
2015 and again in 2020, as shown in the table below. The standards also include a long-term
(annual) target for PM2.5.132

270. While there are no Canadian Ambient Air Quality Standards for levels of NO2, the
Alberta Ambient Air Quality Objectives have guidelines for NO2 levels.
11.2 Views of the applicant
271. TAMA Power retained Intrinsik to evaluate the predicted levels of NO2 and PM2.5 in the
ambient air with the addition of the proposed power plant, and the levels of NO2 and PM2.5
associated with adverse health effects in humans. Intrinsik also responded to Dr. Vipond’s report.
272. When discussing whether exposure to the project’s emissions, including NO2 and PM2.5,
could be hazardous to health, Intrinsik stated that a chemical could be considered toxic if it has
the capacity to cause health effects. However, there is no risk if there is not enough exposure.133
Intrinsik explained that there is a “dose-response relationship” that defines the type and extent of
injury that can be produced by a chemical as a function of its intrinsic toxicity and the amount,
duration and frequency of the exposure.
273. Intrinsik cited several sources that suggested there is no evidence that NO2 causes
clinically relevant effects in asthmatics at concentrations up to 1,100 µg/m3.134 Intrinsik stated the
predicted peak one-hour NO2 concentration at sensitive sites, such as residential, school and
recreational locations, is 190.4 µg/m3 and the concentration at the maximum point of
impingement (MPOI) where exposure to air emissions is greatest, is 426.8 µg/m3. Based on these
exposure levels, Intrinsik did not expect the air concentration in the area, including the predicted
contributions of NO2 from Sundance 7, to result in any adverse health effects.
274. As with NO2, Intrinsik predicted the MPOI for PM2.5 under the baseline and application
cases135 and the concentrations levels at sensitive areas, such as residences, schools and
recreational areas. The MPOIs were generally found around the project area and not in close
proximity to the sensitive areas. As shown in the table below, Intrinsik found an increase of
predicted 24-hour concentration of PM2.5 from 17.2 µg/m3 to 17.4 µg/m
3 at the MPOI. The
predicted 24-hour concentration of PM2.5 in sensitive areas ranged from 5.7 to 13.9 µg/m3 in the
baseline case to between 6 and 14 µg/m3
in the application case. These concentrations are well
under the Canadian Ambient Air Quality Standards for both 2015 (28 µg/m3) and 2020
(27 µg/m3). The predicted annual concentration of PM2.5 increased by 0.1 µg/m
3for the MPOI
and for the school. The predicted MPOI annual concentration was 4.5 µg/m3 and the sensitive
areas ranged from 1.3 to 2.5 µg/m3, considerably less than the Canadian Ambient Air Quality
Standards of 10 µg/m3 (2015) and 8.8 µg/m
3 (2020).

275. Intrinsik stated that under existing conditions, when the contribution from forest fires is
excluded, NO2 concentrations in the area consistently meet the Alberta Ambient Air Quality
Objectives and PM2.5 concentrations are below Canada-wide standards.
276. In its report, Intrinsik stated that epidemiological studies exploring the relationship
between short-term PM2.5 exposure and health effects tend to estimate the change in rate of
disease to large increases in PM2.5, such as an increase of 10 µg/m3. It added that it was difficult
to determine the magnitude of change in the frequency of mortality or morbidity due to small
changes in PM2.5. According to Intrinsik, the U.S. Environmental Protection Agency considered
air quality down to the lowest measured levels of 5.8 µg/m3 as long-term averages. Data less
than the lowest measured level is extrapolated and not measured, increasing uncertainty.
Intrinsik’s report showed that the predicted annual concentrations of PM2.5 in the project area
were less than the lowest measured level.
277. Intrinsik concluded that both the NO2 and PM2.5 emissions from the proposed power
plant are not expected to appreciably increase the risk of adverse health effects in the study area.
The change between the predicted air concentrations currently (the baseline case) and the
cumulative emissions with the addition of the proposed power plant (application case) are
negligible to low.136
278. In response to the Gunn Métis’ concern about the project’s effects on air quality in the
Capital Region, Intrinsik stated that based on Golder’s air modelling and the predicted levels of
NO2 and PM2.5, it did not expect any health-related effects in the Edmonton area.
279. In response to the Cymbaluk family’s concerns about health, TAMA Power reviewed
the 2006 Wabamun and Area Community Exposure and Health Effects Assessment Program -
Final Report filed by the Cymbaluks and submitted that this report was not representative of
regional ambient air quality. TAMA Power also indicated that the report concluded that local air
quality was good and met air quality guidelines and that incidences of respiratory diseases in the
region are comparable to other areas within and outside Alberta.
280. In response to the Gunn Metis’ concerns with the health risk from polycyclic aromatic
hydrocarbons (PAH), TAMA Power stated that Sundance 7 is expected to produce very low
levels of PAH because the proposed power plant would use equipment with a high efficiency of
natural gas combustion.137 PAHs are primarily formed from low-efficiency combustion of fossil

fuels. TAMA Power submitted that because Sundance 7 is a highly efficient combined-cycle gas
turbine, it is not expected to impact the health of traditional plants or of the people that use them.
11.3 Views of the Cymbaluks
281. The Cymbaluks listed general concerns arising from the project such as air contaminants
and pollution, human health impacts such as respiratory and cardiovascular diseases, and air
quality impacts. They stated that public health concerns already exist in the community and
broader region.
282. The Cymbaluks included a study entitled 2006 Wabamun and Area Community
Exposure and Health Effects Assessment Program - Final Report138
in their submission. This
report, which expanded upon their concerns,139 found an increased prevalence and frequency of
respiratory disorders in the Wabamun area.
11.4 Views of the Gunn Métis
283. The Gunn Métis advocated for the establishment of thresholds for ambient air quality
that are protective of the health of its members. It requested that the Commission condition any
approval to this effect.
284. The Gunn Métis’ members have lived with the impacts of air pollution for many decades
and were concerned with the potential health impacts of increasing air emissions where they live
and exercise their traditional activities. The members spoke of asthma and other respiratory
diseases in the community.
285. Dr. Vipond who was retained by the Gunn Métis, reviewed and interpreted medical
literature to provide the effects of emissions on human health. He also provided an opinion about
the emission levels of Sundance 7 and its impacts on the Capital Region airshed. Dr. Vipond
stated that his conclusions in this regard were based on literature cited in his report and
TAMA Power’s application.
286. Dr. Vipond’s report indicated that the combustion of natural gas produced PM2.5, SOx
and NOx and that more PM2.5 was produced through secondary reactions in the atmosphere. He
stated that there was a direct relationship between exposure of these substances and mortality,
and that there was no safe exposure limit to PM2.5 and ozone.140 He also stated that exposure to
these substances was associated with small birth weight babies, respiratory disease,
cardiovascular disease, strokes and autism.
287. In his report, Dr. Vipond stated that NO2 irritated the lungs and was dangerous to those
with pre-existing respiratory conditions. He cited studies that noted associations between levels
of NO2 in the Edmonton area with emergency room visits for stroke, pediatric asthma and
cardiac and respiratory disease.

46 • Decision 3183-D01-2015 (June 9, 2015)
288. Dr. Vipond added that the composition and effects of PM2.5 vary greatly and cited
studies that indicate combustion-related PM2.5, not naturally occurring PM2.5, is associated with
mortality, as well as cardiac and respiratory diseases. He referred to studies that linked PM2.5 to
cardiovascular events and autism, and indicated long-term exposure had a more severe effect
than short-term exposure.
289. Dr. Vipond found in his report that Sundance 7 would substantially increase primary
PM2.5 and would significantly increase SOx and NOx. However, when questioned at the hearing,
he indicated that he wanted to strike the words from his report referring to smaller but significant
increases of SOx, and acknowledged that SOx levels were not really a concern for the
TAMA Power application.141
290. Dr. Vipond is concerned that the emissions from the project may impact the health of
residents in the Capital Region. He referred to the December 2014 report of the Government of
Alberta on the Capital Region and PM2.5.142 In that report, the annual assessment of ambient air
quality showed that Edmonton Central and Edmonton East ambient air quality monitoring
stations within the Capital Region were in exceedance of the Canada-wide standards for PM2.5.
291. In response to questions about his opinion that the air quality in Edmonton and the
Capital Region would be affected by the proposed power plant, Dr. Vipond stated that this was
“common sense”. He further clarified that when he said, in his opening statement, that
Sundance 7 would increase the primary PM2.5 in the area by 5.2 per cent, he was referring to the
total increase in emissions from stacks and not an increase in ambient air concentrations.143
292. Andrew Read of the Pembina Institute acknowledged at the hearing that although he is
not a health expert, his research indicated that the Edmonton area has been experiencing
exceedances of PM2.5 and a response plan is required to reduce the air pollution in order to
minimize the associated health risks. The report stated that the secondary formation of PM2.5
from NOx and SO2 have the greatest human health impacts, and could cause respiratory and
cardiovascular impacts.144
293. Karen Kubiski stated that one purpose of her report was to identify possible health risks
attributed to PAH absorbed by ethnobotanical species. Ms. Kubiski classified PAHs as a group
of persistent organic contaminants that are considered highly carcinogenic.145 In her report, she
stated that natural gas combustion produces PAH and plants take up PAH if it is present in the
soil, the air, or on a plant’s leaves. The report stated that there may be health impacts if
ethnobotanical plants take in PAH and are used medicinally or as food. Ms. Kubiski clarified that
her report did not comment on the PAH levels produced by Sundance 7.

295. Elders of the Paul First Nation also expressed health concerns about the project.
Edward Adams stated that he was concerned about the deadly effects of carbon monoxide.146
Lloyd Saulteaux stated that he was concerned about the effects of the project on locally collected
medicines and food that the Paul First Nation use and depend upon.
296. Geordy Saulteaux expressed general concerns about air quality. Mr. Saulteaux stated he
lived approximately a mile from the shore of Lake Wabamun and expressed concern that he has
been breathing that air all of his life, and that small children that live there have to breathe the air
that currently contains fly ash.147
11.6 Commission findings on expert objectivity and weight
297. The Commission finds that Dr. Davies provided evidence that was consistent with his
experience in a relatively objective manner. He demonstrated considerable knowledge of the
health-related issues raised in the hearing. The Commission found him to be credible and his
evidence to be useful.
298. Dr. Vipond has experience and expertise in human health as an emergency room
physician. He also provided an opinion about the general health effects of the project on
Gunn Métis members and stated that his conclusions in this regard were based on his review of
literature. Dr. Vipond did not, however, appear to have specialized knowledge of, or experience
with air emissions and their health effects specifically. Consequently, the Commission finds that
Dr. Vipond lacks the necessary skills, experience and training to comment on the interpretation
of epidemiologic studies or air modelling. This apparent unfamiliarity was taken into account by
the Commission when it weighed Dr. Vipond’s evidence on the general health impacts of the
project.
299. The Commission accepts Ms. Kubiski as an expert in vegetation ecology specializing in
ethnobotany.
11.7 Commission findings on air quality in the project area
300. The evidence before the Commission was that power plant air emissions can be
associated with adverse health effects and although all experts agreed that emissions may cause
health effects, they disagreed about the level at which such adverse effects may occur.
301. TAMA Power’s witnesses stated that if the cumulative emissions, including the project’s
contributions, were evaluated, they would be below the levels at which health effects would
occur. In contrast, Dr. Vipond stated that there would be an increase in health-related concerns
from emissions as a result of the project’s effects on air quality.
302. While the potential adverse health effects of NO2 and PM2.5 are not questioned, what is
questioned is whether the emissions from Sundance 7 would cause these health effects.
303. It was Dr. Vipond’s evidence that there is no safe emission levels for PM2.5 and ozone.
The Commission does not find the studies cited by Dr. Vipond to be compelling evidence that
there is no safe level of air emissions. In addition, the studies cited by Dr. Vipond contained

Sundance 7 Power Plant TransAlta MidAmerican Partnership
48 • Decision 3183-D01-2015 (June 9, 2015)
emission level data which far exceeded the levels that would be present in the study area should
the project be approved.
304. Dr. Vipond’s report discussed the health impacts of PM2.5 and NOx, such as respiratory
and cardiovascular disease, morbidity and mortality. His evidence does not demonstrate that
Sundance 7 is a significant source of these emissions or that the net increase in emissions would
result in these health effects. Dr. Vipond did not correlate the levels predicted by Golder’s air
modelling with the health effects that would result. In addition, he provided little rationale for his
predictions on the number of people who would experience health effects from the project.
305. The Commission recognizes that the incremental difference in emission levels due to the
project would be minimal. It also agrees with Dr. Davies that a “dose-response relationship”
between emissions of NOx and PM2.5 and health must be considered and finds that the expected
‘dose’ caused by the addition of the Sundance 7 air emission levels is low enough that an adverse
health impact, or ‘response’, is unlikely.
306. Having regard to the health-related evidence on the record, the Commission finds that
the most persuasive evidence is the Canadian Ambient Air Quality Standards, in which
Health Canada and Environment Canada have specified objectives for the protection of human
health.
307. The Commission observes that the proposed exceedances of Alberta’s Ambient Air
Quality Objectives are consistent with existing levels, with the exception of one exceedance of
CO levels that would result from the proposed power plant idling. The number and duration of
the PM2.5 exceedances with the addition of the project would remain unchanged from the status
quo. There was no evidence before the Commission that the 0.04 µg/m3 increase in the
cumulative PM2.5 emissions or the one exceedance of CO levels would create any adverse health
effects on members of the public.
308. Having regard to the foregoing, the Commission finds that adherence to the predicted
emissions levels will protect members of the community, including those with asthma, from
health effects related to PM2.5 and NOx emissions.
309. The Commission has reviewed the evidence on the health effects of emissions from
Sundance 7 on the Capital Region, including Edmonton. In the Commission’s view, the evidence
does not support the proposition that the emissions produced by the project are likely to result in
health effects to those living in the Capital Region because on the basis of the results of the air
modelling, there would be no appreciable change in air quality.
310. Dr. Vipond did not provide a basis for his predictions about air quality in Edmonton
resulting from the proposed power plant. As the Commission understands it, Dr. Vipond did not
take into account the emissions levels predicted by Golder’s air quality modelling.148
311. The evidence on the record of this proceeding does not support the Gunn Métis’
assertion that air emissions from the project will result in adverse health effects for its members.
To the contrary, the evidence before the Commission is that the levels of emissions, including
PM2.5, would be below the standards and objectives designed to be protective of human health.

Decision 3183-D01-2015 (June 9, 2015) • 49
Consequently, the Commission finds that the evidence before it supports the conclusion that air
emissions from the project would not be associated with any increased health effects.
312. While Ms. Kubiski’s report comments on the health impacts associated with PAHs,
consideration of the emission levels from Sundance 7 was absent. In this regard, the evidence
submitted by TAMA Power indicates that the project will be an insignificant source of PAHs.
The Commission therefore finds that there is insufficient evidence before it to support the
conclusion that there will be any adverse health effects to Gunn Métis members who may ingest
or otherwise contact plants growing in the project area.
12 Construction and traffic
12.1 Views of the applicant
313. TAMA Power heard various concerns related to construction activities. TAMA Power
stated that the effects of construction would be temporary and protocols would be in place to
address construction-related issues.149
314. TAMA Power would form a working group to understand and find solutions to traffic
concerns and to develop and implement a well-managed traffic plan. It would plan to bus
employees to and from work and would encourage its engineering, procurement and construction
contractor to do the same.150 It would also coordinate the timing of shifts with existing TransAlta
operations to stagger start and stop times and minimize traffic on the roads.151 Material deliveries
would be scheduled to not interfere with peak traffic periods.
315. Workers and contractors accessing the project site would be requested to use
Highway 627 and Range Road 42, instead of going through the Paul First Nation’s reserve to
minimize additional traffic on the reserve.152
316. TAMA Power would enforce a zero-tolerance policy on unsafe driving and would work
with local authorities to ensure its workers were using the roads safely.153
317. With respect to construction noise, TAMA Power stated that it would comply with
Parkland County noise bylaws and would limit work to a daytime schedule, except the final
months, where construction is primarily indoors.
318. TAMA Power stated that employees and contractors found trespassing on private land
would be reprimanded. Signage would be posted along the property line, clearly identifying
private property, to mitigate the chance of trespass. A fence would also be built around the work
site.

12.2 Views of the Cymbaluks
319. The Cymbaluk family is concerned that construction activities associated with the
project would bring increased dust, noise, traffic and development impacts.154 Family members
also had previously experienced trespass on their property and are concerned that this will arise
again with construction activities.
320. In addition, the Cymbaluk family is concerned about road safety and increased traffic
because there are already problems with reckless driving on Range Road 42. TAMA Power
intends to use Range Road 42 to bypass the Paul First Nation, but that road goes past the
family’s residence.155
12.3 Views of the Gunn Métis
321. The Gunn Métis anticipated an influx of non-community members for the construction
and operation of the project which would increase garbage and traffic, specifically on
Sundance Road.156
12.4 Views of the Paul First Nation
322. The Paul First Nation is concerned primarily with increased traffic through the reserve
and speeding. The Paul First Nation said that while TransAlta personnel try to respect speed
limits, the general public speeds through.157
12.5 Commission findings
323. The Commission heard multiple parties’ concerns with increased traffic, especially
during the construction of the proposed power plant. The Commission agrees with TAMA Power
that these impacts are temporary in nature and finds that TAMA Power’s mitigation methods
would adequately address these concerns. Additionally, busing staff and scheduling shift changes
and deliveries would help alleviate traffic issues. The Commission also considers that using
Highway 627 and Range Road 42 would minimize any traffic increase for the Paul First Nation
and is encouraged by TAMA Power’s commitment to safety and enforcing a zero-tolerance
policy toward unsafe driving.
324. The Commission finds TAMA Power’s proposed course of action to address the issues
of construction noise and potential trespass raised by the Cymbaluk family to be reasonable.
Construction would be primarily limited to daytime activities and associated noise would be
temporary. The project worksite would also be fenced, which would minimize the chance for
accidental trespass onto the Cymbaluk family’s land.
325. The Commission is satisfied that TAMA Power has provided adequate mitigation
measures to reduce the impacts that would result from the construction and increased traffic at
Sundance 7.

13 Safety
13.1 Views of the applicant
326. As described in the application, the proposed power plant initially utilized anhydrous
ammonia, which would be used in the selective catalytic reduction system to reduce NOx
emissions. The inclusion of a selective catalytic reduction system in a natural gas power plant is
a requirement of ESRD and the Clean Air Strategic Alliance.
327. Ammonia is a corrosive chemical that can be in solid or gaseous form and can irritate
the skin, eyes and lungs and can be life threatening in severe cases. The table below summarizes
potential health impacts caused by ammonia at various concentrations.158
Ammonia concentration (ppm) Resulting Conditions on Humans
5 - 25 Minor irritation of the eye and respiratory tract, odour threshold by most persons.
20 - 30 Eye and respiratory tract irritation in unadapted individuals for 10-15 minutes
25 Marked eye, skin, and respiratory irritation. National Institute for Occupational Safety and Health Recommended Exposure Limit 8-hour Time Weighted Average
100 No adverse effect for average worker over two hours. Deliberate exposure for long periods is not permitted.
400 Immediate nose and throat irritation. No serious effects after 30 minutes to 1 hour.
700 Immediate eye irritation. No serious effect after 30 minutes to 1 hour.
1700 Convulsive coughing. Severe eye, nose and throat irritation. Could be fatal after 30 minutes.
2000 - 5000 Convulsive coughing. Severe eye, nose and throat irritation. Could be fatal after 15 minutes.
5000 Lowest concentration known to be lethal to humans exposed for 5 minutes via inhalation.
5000 - 10000 Respiratory spasm. Rapid asphyxia.
328. TAMA Power retained Golder Associates to conduct an Anhydrous Ammonia Tank
Risk Modelling Study in September 2014 (the Golder anhydrous ammonia report), which
examined three accidental release cases due to equipment failure, over five atmospheric
conditions, as follows:
Case 1: The liquid release of ammonia due to the tanker truck driving away while still
connected to the storage tank or a rupture of the pipe connecting the ammonia storage
tank to the proposed power plant;
Case 2: The venting of the storage tank, due to the safety relief value, in the event of a
fire; and
Case 3: A full release of the storage tank over a 10-minute period.
329. The Golder anhydrous ammonia report considered the frequency of failure, the
frequency of meteorological conditions that inhibit or enhance the rapid mixing and dispersion of
the ammonia, and the probability of fatality due to a hazardous plume at ground level at
distances downwind of human habitation.

330. Golder selected two endpoint threshold levels for assessing the potential effects
associated with the release of ammonia, the Immediately Dangerous to Life and Health (IDLH)
and the Emergency Response Planning Guide – Level Two threshold (ERPG-2). These are
summarized in the table below.159
NH3 (ppm) Exposure period (sec)
Observed effects
300 1800 IDLH defines a condition that poses a threat of exposure to airborne contaminants when that exposure is likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment. IDLH values are based on the effects that might occur as a consequence of a 30-minute exposure. (NIOSH, 1994’ CDC, 2014).
150 3600 ERPG-2: The maximum airborne concentration below which it is believed nearly all individuals could be exposed for up to 1 hour without experiencing or developing irreversible or other serious health effects or symptoms that could impair their abilities to take protective action (AIHA, 2013, 2014).
331. The Golder anhydrous ammonia report listed strategies designed to mitigate the chance
of an accidental release of ammonia, as follows:160
the anhydrous ammonia storage tanks will be provided with a minimum of two pressure
safety valves;
each ammonia pump will have a safety value at the pump discharge;
ammonia vapour detectors will be provided around the ammonia storage area, in the
ammonia containment pit, near the ammonia unloading station, and at each of the two
SCR skids near the heat recovery steam generators;
the vapour detectors will be coupled to local alarm horns, beacons, and a distributed
control system alarm, which will be located near the ammonia storage area, near the
ammonia vapourizer areas, and near the selective catalytic reduction manifolds by the
heat recovery steam generators;
the selective catalytic reduction system will be equipped with an automatic shutdown
control;
the ammonia storage tank will be equipped with a tank level indicator that is connected to
the distributed control system;
visual and audio alarms viewable from an unloading truck cab that can alert the driver
when a high level is reached during filling of the ammonia storage tank will be installed;
containment around the storage tanks and pumps will be installed; and
a concrete pad unloading area with spill protection, safety barriers and safety
shower/eyewash station will be installed.

332. At the request of the Cymbaluk family, Golder conducted additional modelling under a
different meteorological scenario which the Cymbaluk family believed would be more hazardous
at the family’s residence. After comparing the results of the original modelling with that of the
additional modelling, Golder concluded that the original modelling presented the conditions that
result in the highest risk to the Cymbaluk family’s residence.161
333. On April 2, 2015, TAMA Power indicated that it changed its design to utilize aqueous
ammonia, a less concentrated form of ammonia. TAMA Power submitted a revised risk
assessment prepared by Golder as part of its reply evidence entitled the Aqueous Ammonia Tank
Risk Modelling Study (the Golder aqueous ammonia report).162 TAMA Power stated that with
the change, the 1 in 1,000,000 risk of fatality is predicted to occur approximately 95 metres from
the location of the storage tanks, well within the project site.163 This was based on the probability
of fatality modelled by Golder for aqueous ammonia.
334. The Golder aqueous ammonia report was completed using the same failure scenarios
and other conditions used in its anhydrous ammonia report and showed that at the nearest
residence, the maximum concentration predicted is 150 parts per million (ppm) over the course
of a few seconds.164
335. Golder stated that the change in ammonia resulted in the need for two ammonia storage
tanks instead of one.165 Golder explained that the risk modelling was based on one tank failing,166
because the risk of both tanks simultaneously failing was a more unlikely scenario and would
actually result in a lower risk.167 Golder added that if both tanks did fail, the results would not be
linear in that the risk of fatality or distances would double. It would be a small incremental
change.168
336. In response to earlier concerns that colder temperatures may result in higher
consequences, Golder stated that it used an ambient temperature of 25 degrees Celsius because
Canada Environmental Emergency Regulations (2011b)169 requires that any hazard consequence
modelling be conducted using that temperature. However, when it completed the Golder aqueous
ammonia report, a temperate sensitivity analysis comparing the downwind hazard distance at
four temperatures; negative 6.5, 3.7, 16.3 and 25 degrees Celsius, was conducted. The analysis

showed a downward trend in the predicted hazard distances with decreasing ambient
temperature.170
337. TAMA Power submitted that it would adopt the mitigation strategies from the Golder
anhydrous ammonia report into the revised aqueous ammonia storage tank design.171
338. TAMA Power looked at other risks such as natural gas explosions and hydrogen leaks,
using the CEPA Schedule 1 as a guide, but focused on the ammonia risk because it was the
worst-consequence event. According to TAMA Power, other risks can be more comprehensively
investigated as part of the emergency response planning process.172 TAMA Power stated that it
had not completed its emergency response plan but that such a plan for construction would be in
place prior to beginning site construction activities, and a separate emergency response plan for
operations would be in place prior to the proposed power plant commencing operations.173
339. TAMA Power reiterated its commitment to engage with the Cymbaluk family in the
development of the project’s emergency response plan. It added that it would conduct emergency
response exercises as part of its emergency response plan, and that it would offer to engage
nearby stakeholders to participate in those exercises, including the Cymbaluk family, the Paul
First Nation and other interested stakeholders.174
13.2 Views of the Cymbaluks
340. The Cymbaluks retained Zelt Professional Services Inc. (Zelt) to conduct a review of the
Golder anhydrous ammonia report (the Zelt report).175 The Zelt report commented on numerous
deficiencies in the Golder anhydrous ammonia report, including the temperature under which the
modelling was conducted.
341. In its report, Zelt criticized the Golder anhydrous ammonia report for only considering
the failure of the anhydrous ammonia storage tank, the most significant source and no other
sources of ammonia such as the ammonia delivery trucks, and explosions on-site.176 Zelt also
stated that the Case 1 scenario should have been used as the catastrophic event because it
evacuates the ammonia at a greater rate than the 10-minute release scenario.177
342. Zelt re-evaluated the risk using its own scenarios, frequency of events and modelling
software and concluded that the total risk was similar to that predicted by Golder. Zelt also
criticized TAMA Power for not considering the switch to aqueous ammonia as a mitigation
measure because the use of aqueous ammonia would reduce the toxic gas consequence to within
150 metres of the storage tank.178

343. The Cymbaluk family is also concerned that only one risk, the ammonia, was considered
and a full risk assessment of the operation of the proposed power plant had not been done. It
noted that the closest local responders would be from Wabamun, which is approximately nine
kilometres from the project site.179
344. The Cymbaluk family criticized TAMA Power for not completing an emergency
response plan prior to filing its application with the Commission. The family is of the view that a
robust emergency response plan should be developed in advance of construction and operation
and that the plan should be reviewed and tested by the Commission.180
13.3 Views of the Gunn Métis
345. The Gunn Métis are concerned about safety. Certain members recalled an oil spill into
Lake Wabamun in 2005 and questioned the existence of a plan if a full-scale accident were to
happen.181
13.4 Commission findings
346. The evidence of both Zelt and Golder is that the change from anhydrous ammonia to
aqueous ammonia, as recommended by Zelt in its report, greatly reduces the risk to nearby
residents. While the interveners may have concerns about some of the risk modelling, the
evidence before the Commission is that the potentially fatal results of an ammonia leak are
contained in a small area within the project site boundary.
347. Further, TAMA Power has made two commitments, aimed at safety, that mitigate the
risk related to the use of aqueous ammonia. One is to adopt the mitigation strategies identified in
the Golder anhydrous ammonia report in the aqueous ammonia storage tank design. The other is
to engage with the Cymbaluk family in developing its emergency response plan and with all
local stakeholders in conducting emergency response exercises.
348. The Commission accepts TAMA Power’s explanation for delaying the preparation of a
hazard and risk assessment and emergency response plan for construction and for operations
until its power plant design is finalized. These plans are developed by the engineering,
procurement and construction contractor in conjunction with TAMA Power and cannot be fully
developed until the contractor is selected and the proposed power plant design is finalized.
349. Given the degree of risk and the evidence before it, the Commission does not find it
necessary to require TAMA Power to file its emergency response plan with the Commission for
review as requested by the Cymbaluk family. However, stakeholders should have an avenue to
contact TAMA Power regarding its emergency response plan should the project be approved.
Therefore, any approval would be subject to the following condition:
TAMA Power shall file a letter on the record of Proceeding 3183 advising the
Commission and interested parties when its emergency response plan has been finalized.
This letter shall contain the contact information of the person in charge of the emergency
response plan.

14 Visual impacts
14.1 Views of the applicant
350. Because the project site is partially treed, the number of trees to be removed would be
minimized. The open areas of the project site would be landscaped and new trees would be
planted. Further, the heat recovery steam generator stacks are designed to be approximately
55 metres tall, roughly one third of the height of neighbouring facilities, and the proposed power
plant would be set back from roads to reduce visual impacts.182 TAMA Power submitted visual
renderings, known as photomontages, to demonstrate the impact of the proposed power plant on
the viewscape in the area.
351. TAMA Power acknowledged that the proposed power plant would be visible from some
locations near the project site. However, because the proposed power plant is smaller than the
existing Sundance power plants, it would not overwhelm the viewscape,183 and would not be
visible from Moonlight Bay.184
352. TAMA Power retained Golder to prepare a report, entitled Visible Plume Assessment,
regarding a modelling analysis completed to predict the potential for visible water vapour plumes
(the plume) as well as ground level icing and fogging impacts. The Visible Plume Assessment
presented the potential for fogging and icing associated with the project’s emissions sources.
353. Golder explained that a plume becomes visible when water vapour it contains condenses
either through mixing with the surrounding air, cooling or added moisture. Plumes have the
potential to cause fogging or ice depending on the ambient temperature when the plume comes
into contact with the ground or an elevated surface such as a building roof.
354. Golder indicated that the plume from the proposed power plant would not be large and
would not overtake the sky because it localizes and would dissipate shortly after leaving the
proposed power plant’s cooling towers. In light of the visual angle of the plume to the proposed
power plant, Golder does not anticipate that the plume would be obstructive when observed from
the Paul First Nation’s community.185
355. In response to the Cymbaluk family’s concerns about lighting, TAMA Power committed
to designing the exterior lighting of the proposed power plant to minimize the impact to the night
sky and to neighbours. TAMA Power stated that it would follow the Illuminating Engineering
Society of North America publication IES RP-33-14, “Lighting for Exterior Environments”, and
IES RP-20-14, “Lighting for Parking Facilities”, as recommend by the Cymbaluks’ expert. It
also committed to use LED lighting, using fixtures that follow the Backlight, Uplight, and Glare
rating system, and installing Fixture Seat of Approval lights, as mitigation strategies
recommended by the Cymbaluks’ expert.186
356. TAMA Power stated that Lighting Zones 1 and 2 are applicable to most areas of the
proposed power plant but that certain areas may require special allowance for safety and

allowances that the Model Lighting Ordinance does not take for industrial sites which would be
required for this facility. 187
357. TAMA Power committed to review its lighting designs and plans to ensure the safety of
employees and workers at the project site and, at the same time, to minimize impacts of stray
light to the Cymbaluk family’s residence. More specifically, TAMA Power committed to:188
a. instruct its EPC [engineering, procurement and construction contact] to follow the
Illuminating Engineering Society of North America publication IES RP-33-14 and
IES RP-20-14.
b. follow the International Dark-Sky's Fixtures Seal Approval, for exterior lighting.

358. The Cymbaluk family stated the proposed power plant would create adverse visual
impacts on the family because the family’s home quarter is adjacent to the project site. The
family’s concerns included the visibility of the project during the day as well as the impacts of
light from the proposed power plant on the family’s residence.
359. The Cymbaluks retained Benya Burnett Consultancy (Benya Burnett) to prepare an
expert report on lighting impacts (the Benya report). Generally, light pollution occurs when one
property illuminates another property.189 The Benya report listed light pollution types including
sky glow and over-illumination and the associated impacts including annoyance and disruption
wildlife.
360. Pursuant to the Model Lighting Ordinance, there are lighting zones systems designed to
select a proper light level. The Benya report recommended the use of Lighting Zone 2 for
Sundance 7 and that the Model Lighting Ordinance be followed for all lighting on the project
site, except for the areas the applicant can demonstrate require exemptions.190 Specifically, it
recommended that an investigation be conducted to determine whether Light Zone 1, a darker
zone, could be used for portions of the proposed power plant.191

365. The Commission has viewed the photomontages prepared by TAMA Power which were
designed to provide a representation of the project to area residents and finds that this was a
reasonable approach to take in the circumstances.
366. Although the assessment of visual impacts is subjective in nature, the Commission
recognizes that the project would change the visual landscape in the nearby area. The project site
is partially treed and TAMA Power has committed to landscaping and planting additional trees to
the areas it disturbs. The Commission considers that the visual impacts of the project can be
mitigated by the planting of trees and that no additional visual mitigation measures would be
necessary should the project be approved.
367. The Commission accepts TAMA Power’s commitment to implement the mitigation
measures discussed above as recommended by Mr. Benya to reduce the potential visual impacts
stemming from the lighting of the proposed power plant and finds that these mitigation measures
addressed the concerns of the interveners, for the most part. The Commission expects
TAMA Power to follow its commitment to comply with the applicable lighting standards
including the Model Lighting Ordinance and to only make adjustments to the lighting standards
to ensure the safe operation of the proposed power plant.

by the Sundance Road to the north, the Sundance industrial cooling pond to the west and the
Cymbaluk family’s land to the east.
369. The project site is currently not utilized for industrial purposes, and is therefore referred
to as a “greenfield site” in the TAMA Power application.196 TransAlta has owned the land that
was chosen for the project site since 1975. The project site, the majority of which has historically
been used for agricultural purposes, was previously leased to the Cymbaluk family for
agricultural operations.
370. Site selection took into consideration the existence of TransAlta’s operations in close
proximity to the project, which would allow the proposed power plant to use the infrastructure
and resources in place. The project site is far enough from those operations to avoid operational
conflicts. TAMA Power specifically stated in this regard:
Although the specific location of Sundance 7 is currently not utilized for industrial
purposes, TAMA Power believes that the selected site has some important attributes of a
brownfield site as it allows TAMA Power to take advantage of existing industrial
infrastructure and resources in the immediate vicinity.197
371. The project would utilize the existing Sundance industrial cooling pond, pump house
and river intake structures, thereby reducing the environmental impact of a new facility.
TransAlta has a pre-existing Water Act diversion licence with sufficient capacity to supply the
project. The project site is also in close proximity to existing transmission infrastructure and has
access to a nearby interconnection point.
372. The project site is currently zoned “Resource Extraction” by Parkland County. Power
generation is consistent with this land-use designation and TAMA Power has received support
from Parkland County for the project.
373. Prior to the Paul First Nation filed its statement of intent to participate in February 2015,
TAMA Power was not aware that the Paul First Nation had any concerns relating to siting, and
that there may be graves of Paul First Nation ancestors present on the project site.198,199
374. TAMA Power indicated that if it were to encounter historical resources such as graves,
it would follow TransAlta’s current protocol to comply with the requirements of the
Historical Resources Act. Under the existing framework, if gravesites or other significant
artifacts are encountered during construction of a project, construction must be halted, the
artifact must be documented, and the Paul First Nation must be contacted. In this regard,
TAMA Power referred to a prior project of TransAlta, where it had found some buried remains
and held a memorial at the direction of the Paul First Nation.200

60 • Decision 3183-D01-2015 (June 9, 2015)
375. In response to similar concerns about the existence of potential burial grounds on the
project site from the Gunn Métis, TAMA Power made the following commitment:
TAMA commits to following its historical resources protocols and to ensure local
stakeholders are engaged should historical resources be discovered at the project site
during construction. Further, TAMA commits to notifying the Gunn Métis should a
historical resource be discovered at the project site.201
15.2 Views of the Cymbaluks
376. The Cymbaluk family’s lands are legally described as the northeast quarter of
Section 10, Township 52, Range 4, west of the Fifth Meridian and the southeast quarter of
Section 10, Township 52, Range 4, west of the Fifth Meridian and are used for residential and
agricultural purposes. The Cymbaluk family’s home quarter is located at the southeast quarter of
Section 10, Township 52, Range 4, west of the Fifth Meridian. Their lands are located adjacent
to the project site.
377. The Cymbaluk family holds a right of first refusal for the west half of Section 10,
Township 52, Range 4, west of the Fifth Meridian which includes the lands proposed for the
project. Until recently, the family also held a lease interest in these lands.
378. The Cymbaluks submitted that they had strong concerns and reservations about the
location of the project. They questioned whether there were other potential alternate sites
available for the project that would be better alternatives than the currently applied-for project
site. They also contended that TAMA Power had not demonstrated that it selected a site suitable
for the project.202
15.3 Views of the Gunn Métis
379. The Gunn Métis indicated that the project could potentially impact historical resources.
And more specifically, that there is the potential for the presence of archaeological and historical
resources on the project site. According to the Gunn Métis, the project site’s location within its
traditional territory warrants further investigation to ensure the identification of resources
connected to the Lac St. Anne Métis community.
380. The Gunn Métis also made confidential submissions on the project site’s location in
relation to harvesting locations, submitting that these locations contain medicinal plants and
vegetation that are important to its cultural practices.
15.4 Views of the Paul First Nation
381. The Paul First Nation submitted that the Wabamun area, including the project site, was
protected by Treaty 6203 and that its traditional lands included the project site.
382. During the hearing, Mr. Melanson indicated that members were concerned about the
potential for the project site to contain graves. The Commission heard that the Paul First Nation’s
historical practice is to bury someone in an unmarked grave at the location where the person

died. Lloyd Saulteaux stated that, given this practice, he was not aware of how many gravesites
there may be and that the gravesites could not be located.204 At the hearing,
Rudy Bird Yellowhead testified: There was gravesites in that area, but I'm not familiar with that because of age. I'm
58-year-old, and there's older -- elders older than me that might have knowledge in that
area.205
383. The members of the Paul First Nation allege that because their ancestors were present in
the general area of the North Saskatchewan River, which includes the project site, the project site
may contain unmarked graves of the Paul First Nation’s ancestors.
384. The Paul First Nation’s community is located approximately 800 metres from the
project site. The Paul First Nation submitted that the project would be an expansion of existing
development in the area and would have a compounding effect on the traditional land use of the
Paul First Nation, specifically hunting, gathering, and its way of life. The elders of the
Paul First Nation also testified that they are concerned with the holistic impact on their lives as a
result of the siting of the project.206
15.5 Commission findings
385. In considering the siting of a proposed electric generation facility, the Commission looks
at the suitability of the project site; it does not assess the proposed site to determine whether it is
the best site or assess whether other sites were considered.207 Accordingly, TAMA Power has to
demonstrate only that the project site is a suitable site.
386. This application will stand or fall on the merits of the project site because TAMA Power
applied to the Commission with one single site for consideration.208
387. The suitability of the project site in this instance must be considered taking into account
a number of relevant factors, including:
the potential impacts on local residents and stakeholders;
the proximity to existing transmission facilities;
the availability of water and fuel supplies; and
the nature of the land use in the area.

62 • Decision 3183-D01-2015 (June 9, 2015)
388. The Commission notes that, other than the Cymbaluk family, there were no residents
located within 2,000 metres of the project site who voiced concerns.
389. The Commission accepts TAMA Power’s evidence that site selection took into
consideration the nature of current land use in the area, proximity to existing transmission lines,
and the availability of fuel.
390. The evidence before the Commission is that the project site borders the Sundance
industrial cooling pond, which would be used to obtain and dispose of water for the project. In
addition, the land in the project area is designated as “Resource Extraction” by Parkland County,
which supports the application. This designation allows for construction and operation of the
proposed power plant. Moreover, TransAlta owns the project site, which is partially fenced along
the Sundance 7 road.
391. Both the Paul First Nation and the Gunn Métis urged the Commission to consider the
implication of potential gravesites that may be found on the project site. However, the
Commission finds that there was no persuasive evidence submitted by these interveners in
support of their respective submissions in this regard. Moreover, there is a framework in place to
identify historical resources should any be found, and more importantly, a commitment by
TAMA Power to follow existing protocols and notify the Paul First Nation and the Gunn Métis if
gravesites are found during construction of the project. The Commission finds that the current
framework that is in place to identify gravesites is sufficient in the circumstances.
392. The Commission took into consideration the confidential submissions and evidence on
the project site in relation to the harvesting locations of the Gunn Métis. It also assessed the
current access to these harvesting locations, and such access with the addition of the proposed
power plant.
393. Having considered the evidence, the Commission finds that the location of the project
site is suitable for the construction and operation of Sundance 7.
16 Corporate structure
16.1 Views of the applicant
394. TransAlta MidAmerican Partnership is a general partnership comprised of two partners:
TransAlta Canadian Gas Development LP (TCGDLP) and MEHC Canada Genco Limited
Partnership (MEHCLP).209
395. The applicant explained that TCGDLP, the TransAlta partner in TAMA Power, is
comprised of one limited partner, TransAlta Corporation, holding a 99.99 per cent interest in
TCGDLP and one general partner, 1707226 Alberta Ltd., an Alberta corporation incorporated
under the Business Corporations Act, holding a 0.01 per cent interest in TCGDLP.
1707226 Alberta Ltd. is a wholly-owned subsidiary of TransAlta Corporation.

Sundance 7 Power Plant TransAlta MidAmerican Partnership
Decision 3183-D01-2015 (June 9, 2015) • 63
396. The applicant explained that MEHCLP, the MidAmerican partner in TAMA Power, is
comprised of one limited partner, MidAmerican Canada Holdings Corporation, holding a
99.99 per cent interest in MEHCLP and one general partner, MEHC Canada Genco CP
Corporation, a British Columbia corporation (registered extra-provincially in Alberta), holding a
0.01 per cent interest in MEHCLP. MEHC Canada Genco GP Corporation is a wholly-owned
subsidiary of MidAmerican Canada Holdings Corporation; MidAmerican Canada Holdings
Corporation in turn is owned by MEHC Canada, LLC, a Delaware limited liability company,
which is owned by Berkshire Hathaway Energy Company; and that Berkshire Hathaway Inc.
holds a majority interest in Berkshire Hathaway Energy Company.
397. The applicant explained that TCGDLP is the managing partner of TAMA Power. The
applicant stated that in its capacity as general partner of TAMA Power, 1707226 Alberta Ltd.
will enter into all agreements on behalf of TAMA Power. The applicant requested that all
approvals, licences and permits for the project be issued in the name of 1707226 Alberta Ltd.,
because this entity is the general partner of TCGDLP, the managing partner of TAMA Power.
398. Although TAMA Power is a different entity than 1707226 Alberta Ltd.,
1707226 Alberta Ltd. will ultimately hold the permit and licence should the Commission
approve the proposed power plant.
399. The Cymbaluks submitted that because 1707226 Alberta Ltd. did not file the application
it should be refiled by 1707226 Alberta Ltd. Counsel for the applicant argued in this regard that
there is nothing in the legislation that states that an applicant cannot request that the Commission
issue the licence in the name of a related corporation in order to comply with the Hydro and
Electric Energy Act. TAMA Power stated that 1707226 Alberta Ltd. is a valid entity in
compliance with the Hydro and Electric Energy Act, and is entitled to hold the licence approval
and permit for the project.
16.2 Views of the Cymbaluks
400. The Cymbaluks expressed concerns with the applicant’s corporate structure and its
relation to TAMA Power. The Cymbaluks stated that the applicant’s original application
suggested that TAMA Power is the entity that has applied for permits and licences to construct
and operate the project.210 The Cymbaluks stated that according to TAMA Power’s corporate
structure, TAMA Power is not the entity that has applied for the permit and licence, and that
such entity is in reality 1707226 Alberta Ltd., a general partner, holding 0.01 per cent interest in
the limited partnership on the TransAlta side.
401. The Cymbaluks referred to Section 11 of the Hydro and Electric Energy Act which
states “No person shall construct or operate a power plant unless the Commission, by order, has
approved the construction and operation of the power plant.”211 The definition of persons is
enumerated in Section 28 of the Interpretation Act. TAMA Power, the partnership that filed the
application, is not a legal person permitted to hold an approval for a power plant pursuant to
Section 11 of the Hydro and Electric Energy.

64 • Decision 3183-D01-2015 (June 9, 2015)
402. The Cymbaluks requested that the Commission direct TAMA Power to reapply in the
name of 1707226 Alberta Ltd. In this new application, TAMA Power should clarify its corporate
structure to the Commission and other interested parties.212 It was the Cymbaluks’ view that
TAMA Power must provide “compelling reasons for why [the] proposed corporate arrangement
should be approved or if the public interest would be adequately protected.”213
16.3 Commission findings
403. To be eligible to receive a permit or licence from the Commission, an applicant must
meet the requirements of the Hydro and Electric Energy Act. Section 23 of that act specifies
the types of entities that may receive approval from the Commission and that one permissible
form of corporate entity is to be registered, incorporated or continued under the Alberta
Business Corporations Act. Applicants are not required to meet any other legislative
requirements to be eligible to obtain a licence from the Commission.
404. In the addendum to Decision 2002-089,449 the AUC’s predecessor, the Alberta Energy
and Utilities Board, made the following remarks regarding applicants’ corporate structures:
In the Board’s view, proponents of energy projects may use legitimate and legally
recognized forms of business organization in order to advance their commercial interests.
Corporate configurations such as limited partnerships, limited companies, and joint
ventures are common examples of business organization and, in the absence of
compelling reasons to reject such arrangements, are generally acceptable to the Board.
The existence of limited liability for limited partners, for example, will not of itself be
sufficient reason to deny such an applicant’s project. A similar restriction on liability is
afforded shareholders of a limited company.214
405. The corporate relationship between 1707226 Alberta Ltd., Berkshire Hathaway Energy
Company and TransAlta is a commercial matter. In the Commission’s view, the applicant is
entitled to arrange its corporate structure and affairs in a manner that most effectively advances
its business interests, as long as it complies with Section 23 of the Hydro and Electric Energy
Act. In this case, should the Commission approve the project, the approval would be issued to
1707226 Alberta Ltd. which is a corporation that meets the requirements of Section 23 of the
Hydro and Electric Energy Act.
406. The Commission recognizes that in the initial application there was a question about
which entity was applying to construct and operate the proposed power plant. TAMA Power’s
responses to the Commission’s information requests clarified that, should the project be
approved, the entity that would ultimately hold the approval would be 1707226 Alberta Ltd.
Notably, this information was provided prior to the issuance of the notice of application for this
project.

Decision 3183-D01-2015 (June 9, 2015) • 65
407. The Commission is satisfied, based on the evidence tendered by the applicant, that the
entity applying to hold the approval to construct and operate the proposed power plant, namely
1707226 Alberta Ltd., was incorporated and is currently registered under the
Business Corporations Act, and is therefore eligible to receive an approval for a power plant
from the Commission.
17 Conclusion
408. Earlier in this decision, the Commission explained the legislative framework in place
for the consideration and approval of power plants in Alberta. In this section, the Commission
applies the legislative framework and decides, in accordance with Section 17 of the
Alberta Utilities Commission Act, whether approval of the project is in the public interest having
regard to its social and economic effects and its effects on the environment.
409. The Commission finds that the construction and operation of the project will not affect
the health and safety of area residents.
410. The Commission is satisfied that the applicant’s estimated daytime and nighttime
predicted cumulative sound levels for the project meet the requirements of Rule 012. The
Commission concludes that compliance with daytime and nighttime permissible sound levels for
the project will ensure that noise is acceptable at the nearest residence. The Commission has
imposed a condition on its approval of the project to ensure that the project strictly complies with
Rule 012 and its permissible sound levels.
411. The Commission is of the view that the Cymbaluk family’s noise concerns may be
partially alleviated by adherence to the permissible sound level at their residence and by
including both the overall noise level at their residence and the noise contribution from the
proposed power plant in the comprehensive sound level assessment.
412. The Commission finds that air modelling conducted for the project, with the exception
of the existing PM 2.5 exceedances and the possible CO exceedance, meets the Alberta Ambient
Air Quality Objectives and other guidelines. TAMA Power has indicated that TransAlta
currently intends to commence the decommissioning of coal-fired power plants in the area and,
in so doing, improve air quality in the region. The Commission concludes that compliance with
these objectives will protect nearby landowners and aboriginal groups from any air
emission-related health effects.
413. In addition, the Commission is satisfied that any safety concerns about the project and
its inclusion of ammonia can be effectively mitigated. In making this finding the Commission
observes that TransAlta and other power plant operators use ammonia without incident in their
operations in Alberta and throughout the world and also that there are safety precautions as
recommended by Golder to improve the safety of ammonia transportation and storage.
414. In light of the applicant’s commitment to follow the safety precautions recommended by
Golder, the Commission is of the view that the project’s construction and operation will not
create a material safety risk to members of the public.
Sundance 7 Power Plant TransAlta MidAmerican Partnership
66 • Decision 3183-D01-2015 (June 9, 2015)
415. The Commission accepts TAMA Power’s evidence that the project will create
approximately 500 jobs during construction and another 35 full-time positions during
operations.215 The interveners did not challenge this evidence.
416. Further, the Commission heard that the applicant would hire local employees and use
local services for construction and operation of the project, and that its approval would result in
increased tax contributions for Parkland County. Based on this evidence, the Commission finds
that approval of the project would provide some economic benefit to the community.
417. The Gunn Métis asserted that one of the negative impacts of the project would be a
decrease in ethnobotanically important plants. The Commission determined earlier that approval
of the project would have little, if any, negative impact on ethnobotanically important plants,
with the exception of those plants that may be located within the project site. The Commission
recognizes that Golder’s field work revealed the presence of some ethnobotanically important
plants on the project site. However, given the mitigation measures such as the wetland
compensation, taking into account that the project site is on private land owned by TransAlta and
that it has been used for agricultural operations for many years, the Commission is of the view
that the project’s construction and operation would not create a material adverse impact on
ethnobotanically important plants to the Gunn Métis.
418. Regarding the environmental effects of the project, an important consideration for the
Commission was the applicant’s compliance with various ESRD guidelines applicable to the
project. As stated previously, the Commission regards compliance with the existing regulatory
requirements administered by other public or government departments or agencies to be an
important element when deciding if potential adverse impacts are acceptable. Based on the
evidence submitted by TAMA Power, the Commission finds that the project, if constructed,
would have minimal environmental impacts.
419. Based on the foregoing, the Commission finds that the proposed power plant is in the
public interest.

TransAlta MidAmerican Partnership
Sundance 7 Project
Application No. 1610492
Proceeding No. 3183
Ruling on standing
1 Overview and nature of the issue to be decided
1. TransAlta MidAmerican Partnership (TAMA Power or the applicant) filed an application
with the Alberta Utilities Commission (AUC or the Commission) to construct and operate the
Sundance 7 power plant (the proposed Sundance 7 power plant or the proposed project). The
proposed Sundance 7 power plant is an 856-megawatt (MW) natural gas-fired power plant. The
project is proposed to be located within Section 10, Township 52, Range 4, and west of the
Fifth Meridian, on private lands approximately seven kilometres southwest of
Wabamun, Alberta.
2. On September 10, 2014, the Commission issued a notice of application for Proceeding
No. 3183. The deadline for submissions was October 16, 2014. The Commission received 10
objections, and one letter of support in response to its notice.
3. The Commission must now decide if the persons who filed a submission stating concerns
about, or objections to, the proposed Sundance 7 power plant application have demonstrated that
they have rights that may be directly and adversely affected by the Commission’s decision on the
application. A person who demonstrates the potential for direct and adverse effect is said to have
“standing”.
4. The Commission asked me to write to you to provide its ruling and reasons for its ruling
on the standing of those persons who filed submissions on the record of Proceeding No. 3183.
2 Objections and statements of intent to participate
5. The Commission received objections to the proposed project from the following
individuals represented by Mr. Richard Secord of Ackroyd LLP: Ferne Cymbaluk,
Phillip Cymbaluk and David Cymbaluk.
6. These persons indicated that they own and occupy land within 800 metres of the site of
the proposed Sundance 7 power plant. In their respective statements of intent to participate, these
persons expressed a number of concerns about the proposed project, including: location of the
proposed project, impacts to health and safety, visual impacts, environmental impacts,
The Alberta Utilities Commission December 11, 2014 Page 2 of 9
operational impacts, economic effects, land value impacts, as well as traffic and noise. These
persons also raised concerns about the applicant’s consultation program and allegations about
shortcomings in the application.
7. On June 18, 2014, the Commission received a submission from
Tammi Cymbaluk Breymann who indicated that she owns property located approximately three
kilometres from the site of the proposed Sundance 7 power plant. In her statement of intent to
participate, Ms. Cymbaluk Breymann stated that the proposed project, in combination with
existing coal mines, would have adverse effects and specifically mentioned noise, traffic, land
devaluation, and environmental impacts such as dust, air emissions and water quality.
8. On October 17, 2014, the Commission received a statement of intent to participate from
the Summer Village of Kapasiwin (Kapasiwin) located at the end of Lake Wabamun. The
concerns expressed included traffic, noise, air emissions, and the potential impact of the
proposed project on Lake Wabamun and its watershed.
9. The Commission received statements of intent to participate from Linda Duncan,
Donna Thomas, and Barbara Henderson who all indicated that they own or reside seasonally on
properties located in Kapasiwin, which is approximately six to seven kilometres from the site of
the proposed Sundance 7 power plant (collectively, the Kapasiwin residents). In their respective
submissions, these parties indicated that they are recreational users of Lake Wabamun. Their
concerns include noise, air emissions, cumulative effects, and the proposed project’s impacts on
Lake Wabamun, including its water levels, fish and wildlife.
10. On October 18, 2014, the AUC received an email from the Mewassin Community
Council indicating that it intended to apply for intervener status in this application. The email
was uploaded on the record of Proceeding No. 3183 on October 28, 2014. The Mewassin
Community Council’s statement of intent to participate indicated that its members reside in
Keephills, Duffield, Cavel, Genesee, Stony Plain and Edmonton. The concerns expressed related
to increased air emissions arising from the construction and operation of the proposed
Sundance 7 power plant.
11. On October 16, 2014, the Samson Cree Nation (Samson Cree) filed a statement of intent
to participate on the record of Proceeding No. 3183. The Samson Cree requested that the
Commission assess the potential adverse effects, including cumulative impacts of the proposed
Sundance 7 power plant on the Samson Cree’s aboriginal and treaty rights. The Samson Cree
stated that the application, as filed, did not meet the requirements of AUC Rule 007:
Applications for Power Plants, Substations, Transmission Lines and Industrial System
Designations as it had not been adequately consulted. The Samson Cree submitted that the
proposed project is located within its traditional territory and that Lake Wabamun is a place of
cultural and spiritual significance. It also submitted that Treaty No. 6 protects its right to hunt,
trap and fish throughout all of its territory, including the Wabamun area. Further, the
Samson Cree indicated that the application does not adequately address environmental impacts.
12. On October 17, 2014, the Alexis Nakota Sioux Nation (Alexis Nakota Sioux) submitted a
statement of intent to participate with respect to the proposed project application. The Alexis
The Alberta Utilities Commission December 11, 2014 Page 3 of 9
Nakota Sioux submitted that its members continue to use the area surrounding the proposed
Sundance 7 power plant in order to exercise aboriginal and treaty rights, which is located
approximately 18 kilometres from its main community. It stated that there are a number of
traditional use sites within the area of the proposed Sundance 7 power plant including hunting
areas, fishing areas, plant harvesting sites and ceremonial sites and that the proposed Sundance 7
power plant would directly and adversely affect its members’ use of these sites.
13. The Alexis Nakota Sioux submitted, among other things, that the construction of a new
pump house to withdraw water resources necessary for the proposed project would disturb the
wildlife habitat and migratory patterns by increasing access, noise and activity that would cause
animals to avoid the area which, in turn, would impact hunting. It added that construction and
operation of the proposed project would be disruptive to wildlife habitats and would drive game
elsewhere.
14. Lastly, the Alexis Nakota Sioux submitted that it had not been consulted.
15. The Gunn Métis submitted a statement of intent to participate on October 17, 2014 that
explained that the proposed Sundance 7 power plant is within its deemed territory. The
Gunn Métis stated that it had not been consulted by the applicant and that the application, as
filed, does not consider the Gunn Métis’ traditional knowledge, use and aboriginal rights in the
area of the proposed Sundance 7 power plant. It added that according to its traditional
knowledge, fisheries would be impacted because the thermal balance on Lake Wabamun would
change as a result of the cooling pond’s impacts on water temperatures. According to the
Gunn Métis, warm water will prevent Lake Wabamun from freezing in future winters. The
Gunn Métis indicated that there are harvesting locations both in, and immediately adjacent to, the
proposed Sundance 7 power plant.
16. In support of its statement of intent to participate, the Gunn Métis filed two maps which
were granted confidential status in the Commission’s October 29, 2014 ruling. These maps show
the exact locations of aboriginal harvesting sites, which can be found within two kilometres of
the site of the proposed Sundance 7 power plant.
17. On October 16, 2014, the Commission received a letter of support from the Village of
Wabamun. The Village of Wabamun stated that it supports the proposed Sundance 7 power plant
because it would create economic opportunities. It also stated that the applicant has been a
responsible corporate citizen, caring for the environment and that the generation is needed for the
province.
18. In four separate letters dated November 7, 2014, the applicant submitted comments on
the standing of each of the parties who had filed statements of intent to participate on the record
of the proceeding.
19. With respect to the Gunn Métis, the Samson Cree and the Alexis Nakota Sioux
(collectively, the aboriginal groups), the applicant submitted that none of these parties has met
the “directly and adversely affected” test for standing established pursuant to the Alberta Utilities
Commission Act. Specifically, the applicant submitted that none of these aboriginal groups has
The Alberta Utilities Commission December 11, 2014 Page 4 of 9
established, on a factual basis, the potential for direct and adverse effect and that, among other
things, there is no Crown land within 2,000 metres of the proposed project site other than a
portion of the Paul First Nation Reserve; hence, it is unclear where these parties could exercise
their aboriginal and treaty rights within 2,000 metres of the site of the proposed
Sundance 7 power plant.
20. Regarding each of the aboriginal groups’ submissions that the proposed
Sundance 7 power plant will be located on their traditional lands, the applicant stated that the
aboriginal groups’ members’ ability to use their traditional territory would be unaffected by the
construction and operation of the proposed Sundance 7 power plant. The applicant noted that the
proposed Sundance 7 power plant would be located entirely on its privately-owned land, and
consequently, no public or Crown land would be disturbed. The applicant further submitted that
there are minimal expected impacts on wildlife and water use from the proposed
Sundance 7 power plant’s construction and operation.
21. The applicant also filed a confidential response to the aboriginal harvesting locations
identified by the Gunn Métis.
22. In its November 7, 2014 letters, the applicant indicated that it did not object to the
Cymbaluk family (Philip, Ferne and David) being granted standing.
23. However, with respect to the remaining parties who filed statements of intent to
participate, the applicant submitted that these parties have not demonstrated the potential for
direct and adverse effect because the land they own and or reside on is far enough away from the
site of the proposed Sundance 7 power plant that they will experience no direct effects.
24. By letter dated November 10, 2014, the Commission allowed interested parties to reply to
the applicant’s comments on their standing.
25. The Commission received a submission from the Gunn Metis on November 28, 2014,
which provided further details on the rights exercised within two kilometres of the site of the
proposed Sundance 7 power plant.
26. The Commission also received a submission from Kapasiwin, which identified the legal
rights it was asserting, including the right of its ratepayers and residents to use and enjoy lands
set aside for recreational purposes free of air and noise emissions that may adversely affect their
health or constitute a nuisance. Kapasiwin indicated that it was concerned with fog, pollution,
noise, including low frequency noise, emissions and related health effects. The Commission also
received similar submissions from the Kapasiwin residents, all of whom adopted Kapasiwin’s
submissions and provided further information. In particular, Ms. Duncan indicated that she was
concerned with emissions and stated that her property falls directly within the zone of deposition
of pollutants from the proposed Sundance 7 power plant.

3 Commission findings
3.1 How the Commission determines standing
27. Standing before the Commission is determined by subsection 9(2) of the Alberta Utilities
Commission Act which states:
(2) If it appears to the Commission that its decision or order on an application may
directly and adversely affect the rights of a person, the Commission shall
(a) give notice of the application in accordance with the Commission rules,
(b) give the person a reasonable opportunity of learning the facts bearing on the
application as presented to the Commission by the applicant and other parties to the
application, and
(c) hold a hearing.
28. In Cheyne v. Alberta (Utilities Commission), the Alberta Court of Appeal characterized
Section 9(2) as the equivalent of Section 26(2) of the Energy Resources Conservation Act and
confirmed that there is a two-part test for standing. First, a person must demonstrate that the right
he or she is asserting is recognized by law. Second, a person must provide some information that
shows that the Commission’s decision on the application may directly and adversely affect his or
her rights. The first part of the test is legal; the second part of the test is factual. For the factual
part of the test, the Alberta Court of Appeal has stated that “some degree of location and
connection between the work proposed and the right asserted is reasonable.”1
29. In Sawyer v. Alberta (Energy and Utilities Board) the Alberta Court of Appeal
commented further on the factual component of the standing test and stated that “…in
considering the location or connection, the Board is entitled to look at factors such as residence,
the presence or absence of other wells in the area, and the frequency and duration of the
applicant’s use of the area near the proposed site.” 2
30. The Commission assesses the potential for direct and adverse effect on a case-by-case
basis, having regard for the specific circumstances of each proposed project application and each
application for standing. The Commission considers that the expression of general or broad
concerns about a proposed project, without some link or connection to the demonstrated or
anticipated characteristics of a proposed project will generally be an insufficient basis for
establishing the potential for a direct and adverse effect. In the Commission’s view, this is the
very mischief that the Alberta Court of Appeal identified when it opined that “some degree of
location or connection between the work proposed and the right asserted” is a necessary
ingredient for standing.

2 2007 ABCA 297 at para 16.
The Alberta Utilities Commission December 11, 2014 Page 6 of 9
31. If the Commission finds that a person has standing pursuant to Section 9(2) of the
Alberta Utilities Commission Act it must hold a hearing to consider the person’s concerns about
the subject application. Further, persons with standing have the right to fully participate in the
hearing. The Commission considers this to include the right to file evidence in support of their
position, the right to question or cross-examine the applicant(s) on its evidence and the right to
make argument.
32. In the past, the Commission has allowed persons without standing the opportunity to
provide a brief statement to the Commission that describes their views on the application. In
exceptional circumstances the Commission may also allow parties without standing to fully
participate in a hearing by filing evidence, cross-examining the applicant and giving argument.
However, where all persons with standing withdraw their objections, the Commission may
cancel the hearing even if parties without standing have expressed a desire to participate in that
hearing.
3.2 Standing Ruling
33. The Commission is satisfied that Phillip, David, and Ferne Cymbaluk have demonstrated
that the proposed project application, as filed, has the potential to directly and adversely affect
their rights because they own or reside on lands within 800 metres of the proposed Sundance 7
power plant and are concerned about consultation, health and safety, visual impacts,
environmental impacts, operational impacts, land value impacts, as well as traffic and noise
which relate to the proposed project. In making its determination on standing, an important
consideration for the Commission is these parties’ proximity to the site of the proposed
Sundance 7 power plant. Given the scope of the proposed project and the size of the generator,
the Commission finds that there is a sufficient degree of connection between the ownership and
occupation rights asserted by these parties and the proposed project-associated concerns that they
raised in their objections. As a result, the Commission grants Phillip, David, and
Ferne Cymbaluk standing to participate in a hearing to consider the proposed Sundance 7 power
plant application.
34. Ms. Cymbaluk Breymann resides approximately three kilometres from the proposed
project and did not explain how her rights may be directly and adversely affected by the
Commission’s decision on the application given the proposed project’s distance from the land
she owns.
35. Further, given the general nature of her concerns, the Commission finds that
Ms. Cymbaluk Breymann has not established a sufficient degree of connection between the
project and her rights or interests. Consequently, standing to Ms. Cymbaluk Breymann is denied.
36. Because the Kapasiwin submissions were incorporated by reference into the submissions
of the Kapasiwin residents, these parties’ submissions were considered jointly.
37. Leaving aside the issue of whether each of these parties has a right to use Lake Wabamun
for recreational purposes, it was incumbent upon each party to establish a connection between
The Alberta Utilities Commission December 11, 2014 Page 7 of 9
the concerns expressed and the anticipated effects of the proposed Sundance 7 power plant. In
the Commission’s view, general concerns including concerns about Lake Wabamun and about
cumulative effects provide an insufficient basis for standing, especially given the distance
between the proposed project and these parties’ seasonal residences.
38. Some of the proposed Sundance 7 power plant’s components are located adjacent to
Lake Wabamun and the proposed project would utilize water from the North Saskatchewan
River under an existing water license. Consequently, for the purposes of this ruling, the
Commission is prepared to assume that Kapasiwin and the Kapasiwin residents have a valid
interest in Lake Wabamun. Upon review of the application, the Commission observes that no
additional diversion of water license is required beyond the volumes permitted under the
applicant’s existing license and that the proposed Sundance 7 power plant would discharge waste
water, not into Lake Wabamun, but into a cooling pond. Given the distance of these parties from
the proposed project, and taking into account the specific impacts identified, the Commission is
not satisfied that these parties have demonstrated that the proposed project’s potential impact on
Lake Wabamun has the potential to create direct and adverse impact on these parties’ rights,
interests, or use of Lake Wabamun.
39. The health risks expressed by Kapasiwin and the Kapasiwin residents were very general
in nature. Taking into account the nature of, and the technology used for, the proposed
Sundance 7 power plant, and given the incremental nature of the air quality impacts, and
Kapasiwin and Kapasiwin residents’ distances from the proposed Sundance 7 power plant, the
Commission finds that these parties have not demonstrated that the proposed project has the
potential to result in air quality impacts that may directly and adversely affect their health.
40. The applicant has predicted that the cumulative sound level at the nearest residences will
be increased. However, the application states that the proposed Sundance 7 power plant is
predicted to comply with the daytime and nighttime permissible sound levels at the nearest
residences, as required by AUC Rule 012: Noise Control. The nearest lands for which Kapasiwin
and the Kapasiwin residents have identified an interest in is more than six kilometres from the
site of the proposed Sundance 7 power plant; therefore, the Commission considers that
Kapasiwin and the Kapasiwin residents have not demonstrated that any noise associated with the
proposed project may directly and adversely affect the rights asserted by them.
41. According to Kapasiwin, the AESO has been advised by Focus Equities Ltd. and the
Paul First Nation of their intention to construct and operate a 1000 MW combined cycle,
gas-fired power plant on the Paul First Nation Reserve, which lies adjacent to Kapasiwin and
Lake Wabamun. Kapasiwin submitted that it does not appear that the potential noise and air
emissions from that project, referred to as the “Great Spirit Power Project”, have been considered
in the application for approval of the Sundance 7 power plant. The Commission considers that,
currently, no application for such project has been filed with the Commission and, as such, any
cumulative effects of that proposed power plant cannot form the basis of an application for
standing on the proposed Sundance 7 power plant application.
42. Accordingly, given the distance between their locations and the proposed project, and
considering the potential impacts asserted, the Commission finds that Kapasiwin and the
The Alberta Utilities Commission December 11, 2014 Page 8 of 9
Kapasiwin residents have not demonstrated that the Commission’s decision on the application
may directly and adversely affect their rights and interests. As a result, standing is denied.
43. The Commission considers, for the reasons that follow, that the Mewassin Community
Council does not have standing to participate in the proceeding. Although the Mewassin
Community Council described in its submission the issues that it wishes the Commission to
address in this proceeding, it did not describe the rights it is asserting or how those rights could
be affected by the Commission’s decision on the application. The Mewassin Community Council
submitted that its members reside in the Keephills, Duffield, Carvel, Genesee, Stony Plain and
Edmonton areas, but did not indicate its members’ exact locations and proximity to the site of the
proposed Sundance 7 power plant. The closest municipality, Genesee, is at least eight kilometres
away from the proposed project site. Further, the Mewassin Community Council did not identify
its members or how its members’ interests or rights may be impacted by the Commission’s
decision on the application. The Commission finds that the Mewassin Community Council has
not demonstrated that its members have rights or interests that may be directly and adversely
affected by the Commission’s decision on the application.
44. The Gunn Métis asserted that it enjoys aboriginal rights associated with the ability to use
lands and water in the area of the proposed Sundance 7 power plant for traditional purposes. For
the purposes of this ruling, the Commission is prepared to assume, without deciding, that the
Gunn Métis is entitled to exercise site-specific aboriginal rights in the locations that it asserted in
its submissions.
45. Some of the concerns expressed by the Gunn Métis were specific to certain areas
identified in two confidential maps that its members use for traditional purposes. Other concerns
expressed by the Gunn Métis related to traditional activities at Lake Wabamun. The Gunn Métis
also expressed concerns that were more general in nature and related to the proposed Sundance 7
power plant’s potential impact on area land, water, and air that it claimed would impact the
exercise of its members’ aboriginal rights.
46. The Commission finds, for the reasons that follow, that the Gunn Métis have
demonstrated that its members have rights that may be directly and adversely affected by the
Commission’s decision on the application. Without disclosing the specific areas identified by the
confidential material, the Commission, in making its ruling, considered the proposed Sundance 7
power plant’s location in relation to the areas identified by the Gunn Métis as important for
carrying out traditional activities.
47. The Commission is prepared to assume, without deciding, that both the Samson Cree and
the Alexis Nakota Sioux are entitled to exercise site-specific aboriginal rights in the locations
that they have asserted in their respective submissions. The Commission therefore finds, in
relation to the first part of the standing test, that both the Samson Cree and the Alexis Nakota
Sioux have legal rights which may be directly and adversely affected by the proposed project.
48. The concerns expressed by both the Samson Cree and the Alexis Nakota Sioux with
respect to air emissions were broad and generic. Accordingly, the Commission finds that the
The Alberta Utilities Commission December 11, 2014 Page 9 of 9
Samson Cree and the Alexis Nakota Sioux have not established how their aboriginal and treaty
rights may be directly and adversely affected by the proposed Sundance 7 power plant’s
contribution to air emissions. Furthermore, given the location of the pump house and the other
proposed project components, the Samson Cree and the Alexis Nakota Sioux have not
demonstrated the manner in which the proposed Sundance 7 power plant would impact
Lake Wabamun and their use of Lake Wabamun.
49. The Samson Cree and the Alexis Nakota Sioux submitted that if combined with other
industrial development in the region, the proposed project would make it more difficult for their
members to use land in the proposed project area to exercise their aboriginal and treaty rights,
including harvesting, hunting and fishing. However, in light of the application, the Commission
finds that the concerns they expressed are general in nature and that they have not established a
causal connection between the proposed Sundance 7 power plant that is sufficient to demonstrate
the potential for direct and adverse effect. As a result, the Commission denies standing to the
Samson Cree and the Alexis Nakota Sioux in this proceeding.
50. While Kapasiwin, Ms. Cymbaluk Breymann, Ms. Duncan, Ms. Thomas, Ms. Henderson,
the Samson Cree, the Alexis Nakota Sioux, and the Mewassin Community Council do not have
standing, they nonetheless have two options for participation in the proposed project proceeding.
First, any of these parties may join a person that has standing and participate as a group. Second,
these parties may provide a brief submission at the hearing to express their views on the
proposed project.
3.3 Conclusion
51. As a result of the Commission granting standing to Phillip, David, and Ferne Cymbaluk
and to the Gunn Métis, as specified above, a notice of hearing will be issued shortly.

Application: 1610492
Standing Ruling for the Paul First Nation
1. In this ruling, the Alberta Utilities Commission must decide if the Paul First Nation has
rights that may be directly and adversely affected by the Commission’s decision on the
application. A person who demonstrates the potential for direct and adverse effect is said to have
“standing”.
2. The Commission has ruled on this motion and has directed me to write to interested
parties to advise them of its ruling and its reasons.
Background
3. TransAlta MidAmerican Partnership (TAMA Power or the applicant) filed an application
with the Commission ,on behalf of 1707226 Alberta Ltd., to construct and operate the
Sundance 7 power plant (the proposed Sundance 7 power plant or the proposed project). The
proposed Sundance 7 power plant is an 856-megawatt natural gas-fired power plant.
4. On September 10, 2014, the Commission issued a notice of application for
Proceeding 3183. The deadline for submissions was October 16, 2014.
5. On February 20, 2015, the Paul First Nation filed a submission with the AUC requesting
standing in the above-referenced proceeding.
6. The Paul First Nation indicated that the proposed project is within its traditional territory
and that its reserve is within 800 metres of the proposed project site. The Paul First Nation
submitted that it was concerned with, among other things, cumulative impacts to its aboriginal
and treaty rights from increased traffic, noise and activity. The Paul First Nation stated that its
members conducted hunting, trapping, gathering and other traditional activities on its lands. The
Paul First Nation also requested more time to hire a third party assessment of the compounding
impact of the proposed project on its traditional lands.
7. By letter dated February 23, 2015 the Commission informed interested parties that it
would consider the Paul First Nation’s request for standing, notwithstanding that the deadline to
file statements of intent to participate had past.
8. By letters dated February 23 and February 24, 2015 TAMA Power filed a response to the
Paul First Nation’s statement of intent to participate. TAMA Power indicated that it was
concerned with the filing of a statement of intent to participate at this stage in the process
The Alberta Utilities Commission February 27, 2015 Page 2
schedule. TAMA Power stated that it had consulted extensively with the Paul First Nation about
the proposed project and that the Paul First Nation was aware that the Commission had
established a proceeding to consider the application. TAMA Power submitted that the Paul First
Nation’s request “for time to assess the project” should be rejected, but indicated that it did not
object to the Paul First Nation having standing in the above-referenced proceeding as long as the
current process schedule would be maintained.

Standing ruling
14. For the reasons that follow, the Commission is satisfied that the Paul First Nation has
standing in Proceeding 3183.
15. For the purposes of this ruling, the Commission is prepared to assume, without deciding,
that the Paul First Nation has the rights it has asserted in its statement of intent to participate. The
Commission considers that the Paul First Nation was concerned with cumulative impacts
including increased traffic, noise and activity which relate to the proposed project. In the
Commission’s view based on the nature of the proposed project and associated impacts, the
assertion of a land-based claim within 800 meters of the proposed Sundance 7 power plant site is
sufficient to support an application for standing in this instance. An important consideration for
the Commission was the Paul First Nation reserve’s proximity to the site of the proposed
Sundance 7 power plant.
16. The Commission notes the applicant’s objection to an extension of the process schedule.
However, given the stage of the proceeding and the date of this ruling, the Commission will
allow the Paul First Nation to file its evidence by March 6, 2015. The applicant shall also be
afforded a one week extension to file information requests to the Paul First Nation, if required.
In the Commission’s view, this amendment to the process schedule will not unduly prejudice any
party. In any event, the Commission expects the Paul First Nation to follow the remaining
process steps including the date to file information responses set out in the Commission’s revised
notice of hearing dated February 20, 2015, which is filed in this proceeding as Exhibit
3183-X0131.

is scheduled from 12:30 p.m. to 1:30 p.m. The Commission may sit some evenings
depending upon the need. The Commission will not however sit the evening of April 14,
2014 and the hearing will adjourn at 4:00 p.m on that day.
Intended participation
4. The Commission understands that the applicant TAMA Power, the Gunn Metis Local 55,
and the Cymbaluks intend to question each other, provide evidence and give argument.
The Commission also understands that Parkland County intends to make a statement at
the hearing.
5. However, it is unclear to the Commission how the Paul First Nation intends to participate
in the hearing.
Opening statements and aids to cross-examination
6. Should a party choose to file an opening statement, it should be brief and filed at least
one day in advance of the commencement of the oral hearing. The Commission reminds
all parties that witnesses in its proceedings must confine their testimony to matters set out

in their pre-filed documentary evidence or arising from evidence adduced in cross-
examination.
7. Aids to cross-examination should be provided to counsel for the party under examination
and uploaded to the E-Filing System at least one business day ahead of time.
Witnesses
8. The Commission requests that the parties identify the witness(es) they intend to seat at
the oral hearing and submit the following information for each witness:
name of the witness; and
key areas of responsibility, if applicable.
if the witness is a consultant, a curriculum vitae (if not already filed on the record)
9. Should the parties intend to seat expert witness(es) please see the Commission’s direction
on this matter attached hereto as Appendix 1.
10. The AUC Staff understand that there may be some limited availability of witnesses. For
local intervener witnesses, the Commission will make best efforts to accommodate these
parties during the hearing and will sit evenings if required. With regards to experts,
should a scheduling conflict arise, the Commission will create an order of appearances, in
consultation with parities, and specify the date and time that a particular expert will be
available for cross-examination during second week of the hearing which will be held in
Edmonton.
11. The Commission asks that the above witness information be filed by no later than
Thursday April 9, 2015.

Qualifying witnesses
1. Section 20 of the Alberta Utilities Commission Act, SA 2007c. A-37.2, states that when
the Alberta Utilities Commission (the Commission) is conducting a hearing, it is not bound by
the rules of law concerning evidence that apply to judicial proceedings. The Commission also is
able to determine the processes that best fit the nature of its proceedings. This allows the
Commission some flexibility to determine what evidence to admit and what weight to give the
evidence it admits, while at the same time, adhering to the principles of procedural fairness that
underlie the formal rules of evidence.
2. One of the procedural matters that the Commission deals with is the qualification of
experts. The purpose of qualifying a witness as an “expert” is to allow the witness to provide
relevant opinion evidence. However, the Commission has generally allowed witnesses, whether
qualified as experts or not, to provide opinion evidence where relevant to the scope of a
proceeding. The value ascribed to such evidence is a question of weight, which is a function of
the professional qualifications, specialized knowledge, experience, relevant publications,
industry recognition and independence of the witness.
3. Given the above, the Commission is currently considering whether its current practice of
qualifying expert witnesses is necessary or efficient. The elimination of the need to qualify
witnesses as experts may streamline proceedings and avoid possible disputes over the “expert”
designation, while continuing to allow parties to focus on the issue of the weight that should be
accorded by the Commission to a party’s evidence in the circumstances. To that end, the
Commission has directed the writer to advise parties to this proceeding that it will not be
necessary for counsel to request that their respective witnesses be qualified as “expert” witnesses
with regard to their pre-filed written evidence or testimony at the oral hearing commencing on
April 13, 2015.
4. Given the continued need for the Commission to assess the weight attributable to the
relevant evidence (including opinion evidence), curriculum vitae for the witnesses should
continue to be provided and counsel should continue to review the qualifications of their
witnesses as part of this hearing. Opposing counsel may, of course, question a witness’
qualifications and the credibility of the evidence provided, and opine on the weight that the
Commission should give to the witness’ evidence.
5. With regard to any issues arising regarding cost claims, Schedule A to AUC Rule 009:
Rules on Local Intervener Costs, establishes the same scale of costs for consultant fees, analysts
The Alberta Utilities Commission Page 4
and experts. As such, cost claims submitted by eligible intervener parties for their consultants’
fees are not dependent on those consultants being formally qualified as expert witnesses. The
costs awarded for the participation of consultant witnesses will be assessed on the basis of their
contribution and assistance to the Commission in understanding the issues relevant to the
proceeding.

October 29, 2014 To: Interested Parties TransAlta MidAmerican Partnership Sundance 7 Project Application No. 1610492 Proceeding No. 3183 Commission ruling on a confidentiality request by the Gunn Métis Local 55 1. In this ruling, the Alberta Utilities Commission (AUC or the Commission) must decide whether to grant a request by the Gunn Métis Local 55 (Gunn Métis) for confidential treatment of two maps identifying aboriginal harvesting locations within two kilometres of the proposed project.
2. The Commission has ruled on this motion and has directed me to write to interested parties to advise them of its reasons for this ruling.
Background
3. On October 16, 2014, the Gunn Métis filed a motion with the AUC for a confidentiality order under Section 13 of AUC Rule 001: Rules of Practice (AUC Rule 001). In its October 16, 2014 letter, the Gunn Métis requested confidential treatment of information identifying aboriginal harvesting locations within two kilometres of the proposed project. Specifically, the Gunn Métis requested that the above noted information be treated as confidential and not be filed on the public record. The Gunn Métis submitted that this information relates to plants and other resources which are scarce due to high levels of residential, industrial, and other forms of development affecting the area. The Gunn Métis also submitted that the information would not cause prejudice to the public if kept confidential.
4. The Gunn Métis also requested the Commission’s leave under Section 27 of AUC Rule 001 to file the maps after the deadline for statements of intent to participate has passed.
5. Further, the Gunn Métis requested that any hearing convened be held in camera so that the information in the maps would remain confidential.
6. On October 17, 2014, the Commission issued a letter to interested parties and directed the applicant and any other party who wished to reply, to file a response to the Gunn Métis’ motion by October 27, 2014. The Gunn Métis was given an opportunity to respond by November 4, 2014.
7. On October 23, 2014, the applicant indicated that it did not object to the maps being the subject of a confidentiality ruling.
The Alberta Utilities Commission October 29, 2014 Page 2 of 4
8. By letter dated October 24, 2014, the Gunn Métis indicated that it would not be replying to the applicant’s comments on its motion.
Ruling
9. In issuing this ruling, the Commission has considered all relevant materials relating to the Gunn Métis’ application for confidentiality. References in this ruling to specific parts of the record are intended to assist the reader in understanding the Commission’s reasoning relating to a particular matter and should not be taken as an indication that the Commission did not consider all relevant portions of the record with respect to that matter.
The test for confidentiality
10. The information that the Gunn Métis seeks to keep confidential under Section 13 of AUC Rule 001 are two maps identifying harvesting locations in the project area that the Gunn Métis submits may be directly and adversely affected by the Commission’s decision on the application.
11. The Commission is part of the system of administrative justice and must uphold an open public system. There is a strong presumption in favour of the open court principle in AUC proceedings to ensure the transparency of the Commission’s process from the inception of a matter, and AUC rules reflect this presumption. In its past decisions, the Commission has considered that a confidentiality order should only be issued in limited circumstances because it is part of the system of administrative justice.1
12. Subsection 13(4) of AUC Rule 001 describes when the Commission may issue a confidentiality order. That subsection states:
13.4 The Commission may, with or without a hearing, grant a request for confidentiality on any terms it considers appropriate
(a) if the Commission is of the opinion that disclosure of the information could reasonably be expected
(i) to result in undue financial loss or gain to a person directly affected by the hearing or other proceeding, or
(ii) to harm significantly that person’s competitive position,
or
(b) if
(i) the information is personal, financial, commercial, scientific or technical in nature,
(ii) the information has been consistently treated as confidential by a person directly affected by the hearing or other proceeding, and
(iii) the Commission considers that the person’s interest in confidentiality outweighs the public interest in the disclosure of the proceeding.

The Alberta Utilities Commission October 29, 2014 Page 3 of 4
13. When deciding whether to issue a confidentiality order, in addition to applying the test established in Section 13, the Commission must also bear in mind the direction of Canada’s courts on such matters. In Sierra Club of Canada v. Canada Minister of Finance,2 the Supreme Court of Canada found that a confidentiality order under the Federal Rules of Court should only be granted when:
(a) such an order is necessary in order to prevent a serious risk to an important interest, including a commercial interest, in the context of litigation because reasonable alternative measures will not prevent the risk; and
(b) the salutary effects of the confidentiality order, including the effects on the right of civil litigants to a fair trial, outweigh its deleterious effects, including the effects on the right to free expression, which in this context includes the public interest in open and accessible court proceedings.3
14. The Supreme Court of Canada in Sierra Club also emphasized that the risk in question must: (i) be real and substantial; (ii) be well grounded in the evidence; and (iii) pose a serious threat to the commercial interest in question.4 This is consistent with the requirement in Section 13(4) of AUC Rule 001 which indicates that the party claiming confidentiality must point to the specific harm that would be caused if the information were placed onto the public record. Further, the interest at risk must be one which can be expressed in terms of a public interest in granting confidentiality.
Commission’s ruling
15. With respect to the maps, the Commission is not satisfied that the Gunn Métis has established that the location of its aboriginal harvesting grounds is information that is commercial in nature such that its disclosure could be reasonably expected to result in an undue financial loss or harm significantly the Gunn Métis’, or its members’ competitive position. In the Commission’s view, the location of traditional harvesting grounds more appropriately falls under the category of personal information. In the following section, the Commission will determine whether the maps that are subject to the confidentiality request warrant protection under subsection 13(4)(b) of AUC Rule 001.
16. Subsection 13(4)(b) of AUC Rule 001 requires the Gunn Métis to demonstrate that:
(a) The information contained in the maps is personal, financial, commercial, scientific or technical in nature;
(b) The maps have been consistently treated as confidential by the Gunn Métis; and (c) The Gunn Métis’ interest in confidentiality outweighs the public interest in the
disclosure of that information in the proceeding.

The Alberta Utilities Commission October 29, 2014 Page 4 of 4
17. The Commission considers that the maps contain the exact location of traditional harvesting grounds which the Gunn Métis uses to exercise aboriginal rights. The Commission accepts the Gunn Métis’ submission that the maps have been consistently treated as confidential by the Gunn Métis.
18. Based on the information submitted by the Gunn Métis, the Commission finds that there could be a real and substantial risk to the interests of the Gunn Métis if the maps were disclosed. The information contained in the maps is personal in nature and is sensitive. The maps’ release may prove detrimental to the Gunn Métis’ acquisition of medicinal plants and may impede the Gunn Métis members’ ability to exercise their constitutionally protected aboriginal rights. In this case, the specific harm identified is that members of the public would be given information on the exact location of traditional harvesting grounds and the Gunn Métis’ traditional harvesting of rare plants and other resources may be impacted. Based on the nature of the information depicted in the maps, the Commission considers that the salutary effects of public disclosure in the name of procedural fairness are outweighed by the deleterious effects to the Gunn Métis in this instance. Based on the foregoing, the Commission finds that the Gunn Métis’ interest in confidentiality outweighs the public interest for disclosure and therefore grants the request for confidential treatment of the two maps, for the purposes of Proceeding No. 3183.
19. Should a hearing be held on the project application, the portion of the hearing that may reveal the confidential information contained in the maps would be held in camera.
20. With respect to the Gunn Métis’ request for leave to file the maps after the deadline for statements of intent to participate has passed, the Commission grants the request and will allow the Gunn Métis to file the maps with the Commission by November 4, 2014.
Conclusion 21. Because the Commission has granted a confidentiality order for the maps, the Commission directs the Gunn Métis to submit the maps either via fax or mail by November 4, 2014. The maps will only be available to registered parties who sign the confidentiality undertaking attached to this ruling as Schedule A and filed as Exhibit No. 39.02.
22. The applicant and any other party wishing to receive copies of the maps, should file a confidentiality undertaking on the record of Proceeding No. 3183. AUC staff will then distribute the maps to these parties in due course.

Proceeding 3183
Application 1610492
Commission ruling on a confidentiality request by the Gunn Métis Local 55
1. In this ruling the Alberta Utilities Commission must decide whether to grant a request by
the Gunn Métis Local 55 (Gunn Métis) for confidential treatment of certain will-say statements
of Gunn Métis members and attached maps.
2. The Commission has ruled on this motion and has directed me to write to interested
parties to advise them of its ruling and its reasons.
Background
3. Previously, the Gunn Métis requested confidentiality for two maps that contained the
locations of aboriginal harvesting grounds within two kilometres of the Sundance 7 Project. The
Commission granted this request for confidentiality in a ruling dated October 29, 2014.
4. On February 18, 2015, the Gunn Métis filed a second motion with the AUC for a
confidentiality order under Section 13 of Rule 001: Rules of Practice. The Gunn Métis requested
that its members’ will-say statements, and any maps attached thereto to be filed as evidence in
the proceeding, be treated as confidential and not be filed on the public record.
5. Further, the Gunn Métis requested that any hearing convened be held in camera so that
the information in the will-say statements would remain confidential.
6. The Commission issued a letter to interested parties and permitted the applicant and
any other party to Proceeding 3183 to comment on the Gunn Métis’ motion. On
February 20, 2015, the applicant indicated that it took no position with respect to the matter.
The test for confidentiality
7. As part of the system of administrative justice the Commission must uphold an open
public system. There is a strong presumption in favour of the open court principle in AUC
proceedings to ensure the transparency of the Commission’s process from the inception of a
matter, and AUC Rules reflect this presumption. In its past decisions the Commission has
Alberta Utilities Commission February 26, 2015 Page 2 of 5
considered that a confidentiality order should only be issued in limited circumstances because it
is part of the system of administrative justice.1
8. Subsection 13(4) of Rule 001 describes when the Commission may issue a confidentiality
order. That subsection states:
13.4 The Commission may, with or without a hearing, grant a request for confidentiality
on any terms it considers appropriate
(a) if the Commission is of the opinion that disclosure of the information could
reasonably be expected
(i) to result in undue financial loss or gain to a person directly affected by the
hearing or other proceeding, or
(ii) to harm significantly that person’s competitive position,
or
(b) if
(i) the information is personal, financial, commercial, scientific or technical in
nature,
(ii) the information has been consistently treated as confidential by a person
directly affected by the hearing or other proceeding, and
(iii) the Commission considers that the person’s interest in confidentiality
outweighs the public interest in the disclosure of the proceeding.
9. When deciding whether to issue a confidentiality order, in addition to applying the test
established in Section 13, the Commission must also bear in mind the direction of Canada’s
courts on such matters. In Sierra Club of Canada v. Canada Minister of Finance,2 the
Supreme Court of Canada found that a confidentiality order under the Federal Rules of Court
should only be granted when:
(a) such an order is necessary in order to prevent a serious risk to an important interest,
including a commercial interest, in the context of litigation because reasonable
alternative measures will not prevent the risk; and
(b) the salutary effects of the confidentiality order, including the effects on the right of
civil litigants to a fair trial, outweigh its deleterious effects, including the effects on
the right to free expression, which in this context includes the public interest in open
and accessible court proceedings.3
10. The Supreme Court in Sierra Club also emphasized that the risk in question must: (i) be
real and substantial; (ii) be well grounded in the evidence; and (iii) pose a serious threat to the
commercial interest in question.4 This is consistent with the requirement in Section 13(4) of
Rule 001 which indicates that the party claiming confidentiality must point to the specific harm
that would be caused if the information were placed onto the public record. Further, the interest

at risk must be one which can be expressed in terms of a public interest in granting
confidentiality.
Commission’s ruling
11. In issuing this ruling, the Commission has considered all relevant materials relating to the
Gunn Métis’ application for confidentiality. References in this ruling to specific parts of the
record are intended to assist the reader in understanding the Commission’s reasoning relating to a
particular matter and should not be taken as an indication that the Commission did not consider
all relevant portions of the record with respect to that matter.
12. For the reasons that follow, and subject to the restrictions below, the Commission has
decided to grant, in part, the Gunn Métis’ motion for confidentiality. The Commission
recognizes that granting the confidentiality order will have a negative effect on the open hearing
principle, because any person who does not sign a confidentiality undertaking will be denied
access to the documentation provided and the oral hearing process in which those documents will
be tested. However, it is also important to the Commission, and to all participants, that all
relevant evidence on this topic be filed and tested. In the Commission’s view, granting the
requested confidentiality order will allow the Commission and participants to fully examine and
test potentially relevant evidence that would otherwise be unavailable to it.
13. As the Commission understands it, the Gunn Métis is requesting confidentiality of the
will-say statements of the member witnesses that the Gunn Métis intends to call at the
Sundance 7 Project hearing, as well as any maps that may be attached thereto, because the
following information is contained in these records:
a. the location of specific harvesting grounds;
b. information related to medicinal plants within the project area;
c. health information of Gunn Métis members; and
d. aboriginal traditional knowledge regarding the functioning of the Wabamun Lake
ecosystem.
14. The Commission finds that the information pertaining to the exact locations of traditional
harvesting grounds, including those depicted in the maps granted confidential status by the
Commission’s October 29, 2014 ruling, meets the test for confidentiality. The Commission finds
no need to rule on the information in the will-say statements that discuss the aboriginal
harvesting grounds identified in the two maps because this information is confidential pursuant
to the Commission’s October 29, 2014 ruling. With respect to any other aboriginal harvesting
grounds depicted in maps attached to will-say statements of the member witnesses of the
Gunn Métis, the Commission accepts the Gunn Métis’ submission that the location of harvesting
grounds is personal in nature and is sensitive. The Commission finds that there could be a real
and substantial risk to the interests of the Gunn Métis if the location of the traditional harvesting
grounds were disclosed. The information’s release may prove detrimental to the Gunn Métis’
acquisition of natural resources and may impede the Gunn Métis members’ ability to exercise
their constitutionally protected Aboriginal rights. In this case, the specific harm identified is that
Alberta Utilities Commission February 26, 2015 Page 4 of 5
members of the public would be given information on the exact location of traditional harvesting
grounds and the Gunn Métis’ traditional harvesting of rare plants and other resources could be
impacted.
15. One of the issues raised by the Gunn Métis in this proceeding is the potential for the
Sundance 7 Project to impact the Gunn Métis’ aboriginal harvesting rights. As the Commission
understands it, these harvesting rights include the harvesting of medicinal plants. Publication of
the location of medicinal plants may prove detrimental to the Gunn Métis because members of
the public would become aware of, and may harvest, this scarce resource which, in turn, may
impede the Gunn Métis members’ ability to exercise their constitutionally protected Aboriginal
rights. In the Commission’s view, the location of medicinal plants falls under the category of
aboriginal harvesting grounds and is protected.
16. The Commission understands that the will-say statements may contain information about
the use of medicinal plants to treat Gunn Métis members’ health. The Commission accepts that
the health information of the Gunn Métis members is personal in nature and finds that this
information warrants protection under a confidentiality order.
17. However, the Commission is not satisfied that “aboriginal traditional knowledge
regarding the functioning of the Wabamun Lake ecosystem” is personal information that
warrants protection under a confidentiality order.5 As such, the Gunn Métis shall file the portions
of the will-say statements that contain “aboriginal traditional knowledge regarding the
functioning of the Wabamun Lake ecosystem” on the public record or provide further
information on this matter to the AUC by March 4, 2015.
18. Subject to the above, the Commission is satisfied that the remaining information should
be granted confidential status in this preceding. The Commission considers that the salutary
effects of public disclosure in the name of procedural fairness are outweighed by the deleterious
effects to the Gunn Métis in this instance. Based on the foregoing, the Commission finds that the
Gunn Métis’ interest in confidentiality outweighs the public interest for disclosure and therefore
grants the request for confidential treatment of the will-say statements and maps (subject to the
exception outlined in paragraph 17) for the purposes of Proceeding 3183.
19. In making its ruling, the Commission has accepted the Gunn Métis’ submission that the
information contained in the will-say statements that have been granted confidentiality in this
ruling has been consistently treated as confidential by the Gunn Métis.
20. The portion of the hearing that may reveal the confidential information contained in the
will-say statements will be held in camera.
5 Exhibit 3183-F0019, Gunn Métis Confidentiality Motion, page 2.
Alberta Utilities Commission February 26, 2015 Page 5 of 5
Conclusion
21. Because the Commission has granted a confidentiality order for the above information,
the Commission directs the Gunn Métis to file the will-say statements and supporting maps
either via fax or mail by March 6, 2015. The will-say statements will only be available to
registered parties who sign the confidentiality undertaking attached to this ruling as schedule A
and filed as Exhibit 3183-X0140.
22. The applicant and any other party wishing to receive copies of the information should file
a confidentiality undertaking on the record of Proceeding 3183. Parties shall then request the
confidential information from the Gunn Métis’ counsel.

February 20, 2015 To: Registered Parties TransAlta MidAmerican Partnership Sundance 7 Project Proceeding 3183 Application 1610492-1 Request for further information 1. In this ruling, the Alberta Utilities Commission must determine whether to grant a motion by David Cymbaluk, Ferne Cymbaluk and Philip Cymbaluk (the Cymbaluks) for further and better responses to an information request they asked of TransAlta MidAmerican Partnership (TAMA Power). TAMA Power opposes the motion.
2. The Commission has ruled on this motion and instructed the writer to communicate its ruling to interested parties.
Information request 3. TAMA Power filed its responses to the Cymbaluks’ information requests on January 30, 2015.
4. On February 5, 2015, the Cymbaluks filed a motion with the Commission in which they requested full and complete answers to TAMAPOWE-CYMBALUK-2015JAN016-020, which reads as follows:
(a) Please confirm that Attachment 1 to TAMAPOWE-CYMBALUK-2015JAN016-020- being a report entitled TAMA Power Sundance 7 Anhydrous Ammonia Tank Risk Modelling Study, dated September 2014 (the “Modelling Study”)- was the only such study conducted for this project.
(b) Please confirm that the Modelling Study is simplistic leading to the adoption of a single
frequency of event and that the frequency of event was taken from an old database. (c) Please confirm that the Modelling Study is not presented to rank overall facility hazards
and risks.
Alberta Utilities Commission February 20, 2015 Page 2 of 6
(d) Please confirm that the following hazards were not considered in the Modelling Study:
a. Delivery of ammonia cargo trucks [loading transfers, connecting, human errors];
b. Gas compressor enclosures (2 onsite) [gas leak leading to enclosure explosion];
c. High pressure natural gas pipeline leak (onsite below ground, onsite above ground, off-site below ground) [issues relate to the locations of automatic shutoff valves and their timing for natural gas supply pipelines];
d. Hydrogen gas storage [loading transfers, truck leak explosion of a single tube, or multiple tube, or tank explosion]; and
e. Fuel gas leak into central building [leading to explosion]. (e) Please confirm that the largest offsite consequences will be:
a. gas leak to the building and explosion; and
b. the toxic gas consequence from a catastrophic ammonia tank release. (f) Please confirm that also of concern is the natural gas pipeline along the route and jet
fire/flash fire consequence. (g) Please confirm that the Modelling Study review of the ammonia toxicology used only
longer term and industrial limits. (h) Please indicate whether a wider review of the health hazards would show that ammonia
concentrations at the levels predicted at the residential locations would be extremely uncomfortable.
(i) Please confirm that the closest location would be impacted within only 5 minutes and that
is doubtful that an emergency response plan implementation could contact and resolve shelter or evacuation of someone outdoors at the time of the incident, such as a member of the Cymbaluk family.
(j) Please confirm that the Modelling Study does not provide any information on the probits
(numerical parameters used to calculate the lethality of risk). (k) Please provide information on the probits used to calculate the lethality of risk in the
Modelling Study. (l) Please confirm that the Modelling Study is a simplistic assessment of the frequency of
events and the Modelling Study quotes an older database for frequency numbers providing a high, average and low frequency and that TAMA has used the mean.
(m) Please confirm that a screening hazard assessment would have shown that events could
combine to increase the frequency of some hazards. For example, the ammonia tank
Alberta Utilities Commission February 20, 2015 Page 3 of 6
catastrophic release frequency could be greater than just the vessel failure by considering the other potential major events, such as:
a. Failure of the vessel
b. Nearby fire or explosion of the natural gas compressor buildings
c. Explosion of the central facility catastrophic event. (n) Please confirm that TAMA has claimed to have used only the average (95 per million/yr)
frequency of events for all hazard events in the study and risk calculations as presented in Appendix C without any other modifying factors except the joint frequency of meteorology condition and wind direction.
(o) Please confirm that the results in Table 11 for leaks and catastrophic failure appear to
each use a different frequency which appears to be duplicated using the high and low vessel failure rates.
(p) Please confirm that Table 12 in the Modelling Study appears to correspond to the use of
the average frequency. (q) Please confirm that the Modelling Study used a high ambient temperature in the
dispersion calculations. (r) Please confirm that, in this case:
a. the anhydrous ammonia release is complex;
b. an anhydrous ammonia release will be a mixture of vapour and small droplets of liquid and that this causes the toxic cloud to be cool and dense, and it will tend to have low dispersion and remain near the ground level;
c. therefore, if a high ambient temperature was used in the dispersion modelling, the toxic cloud would be less dense and the calculations in the Modelling Study may not be conservative;
d. more rigorous dispersion modelling may show that for most of the year that is cooler than assessed, and evenings or mornings, the plume may be denser longer than modeled and that this could increase concentrations a factor of two or more.
(s) Please confirm whether TAMA agrees with that the following proposition and if not, why
not:
a. Winds would have to push the dense anhydrous ammonia cloud up the slope from the facility to the residential locations and this was not taken into account by the dispersion modelling used in the Modelling Study. This is like pushing water on a table with your hands; on a flat surface it is relatively easy and just spreads out. On a sloped table, pushing water up the slope spreads the water out more and slows the
Alberta Utilities Commission February 20, 2015 Page 4 of 6
progress. Therefore, the toxic gas cloud could remain longer than predicted at the residential locations, but the concentrations could be higher or lower than predicted depending upon the slope and other terrain influences.
(t) Please confirm that for neutrally buoyant emissions, low wind speeds typically lead to
higher predicted concentrations whereas higher wind speeds will lead to more mixing and lower concentrations.
(u) Please confirm, that for dense gas emissions, as in this study, higher wind speeds may
keep the plume (or dispersing toxic cloud) attached to the ground, because these plumes require a higher Richardson’s number to transition to a lifted plume, leading to higher concentrations than neutrally buoyant plumes (or cloud).
(v) Please confirm whether the PHAST dispersion model, the model used to calculate
downwind concentrations in this assessment, takes into account the delayed transition to a lifted plume for dense gas dispersion.
(w) Please confirm that the Modelling Study used a screening level calculation method that
uses only the 16-point wind direction of the ammonia storage-to residence location and that this reduces the frequency of meteorological events.
(x) Please confirm that a more conservative screening approach would have combined the
neighboring wind rose wind frequencies which would have increased the frequency by a factor of two or three.
(y) Please confirm that that the following mitigation measure were not considered:
a. The use of aqueous ammonia instead of anhydrous ammonia. (z) Please confirm that the use of aqueous ammonia would reduce onsite and offsite
consequence and risk and it would reduce the toxic gas consequence to within 150m or so of the storage.
(aa) Please confirm that that for an aqueous ammonia release, most of the release will rain-out
and form a pool on the ground and that energy from the ground or sunshine and wind creates evaporation and leads to offsite impacts.
(bb) Please confirm that with the release of anhydrous ammonia (to be used at Sundance 7)
adverse conditions worsen with cooler temperatures, moderate winds and cooler ground surfaces.
5. In their motion, the Cymbaluks argued that TAMA Power’s responses did not provide the information requested. They stated that the information was necessary to understand the documentary evidence (namely, the Modelling Study) filed by TAMA Power.
Alberta Utilities Commission February 20, 2015 Page 5 of 6
6. The Cymbaluks also requested, among other things, that the Commission extend the filing of intervener evidence from February 20, 2015, to one week after full and complete answers to the information request have been provided by TAMA Power.
Responses to the motion
7. In its response dated February 12, 2015, TAMA Power claimed that the Modelling Study for the Sundance 7 project was prepared by Golder and Associates for TAMA Power in support of its application to Parkland County for a development permit. TAMA Power argued that it should not be compelled to provide further information because the Commission does not require a proponent to prepare a risk assessment such as the Modelling Study in support of a power plant application. TAMA Power also stated that the information request goes far beyond what TAMA Power is reasonably obligated to respond to under sections 29 to 31 of Rule 001: Rules of Practice.
8. The Gunn Métis Local 55 supported the Cymbaluks’ motion. The Gunn Métis also argued that this information should be provided because it is relevant to issues in the proceeding, including health risks that may be experienced by Gunn Métis members and impacts from ammonia emissions, including odors and adverse impacts to traditional resources such as medical plants.
Cymbaluks’ reply
9. The Cymbaluks filed a reply with the Commission on February 18, 2015. The Cymbaluks submitted, among other things, that the Modelling Study is not a resolved issue, and that public safety, public health, the Modelling Study, and the public interest are all issues still open for the Commission’s consideration in the proceeding.
Commission ruling
10. After reviewing all of the parties’ submissions, the Commission has decided to deny the Cymbaluks’ motion. The Commission finds TAMA Power’s responses to the information request to be adequate in relation to the application before it. The Commission is also persuaded that providing answers to the information request may unduly burden TAMA Power given the stage of the Sundance 7 power plant design. In making this finding, the Commission accepts TAMA Power’s submission that to provide the answers would entail significant additional work.
11. The Commission is not persuaded by TAMA Power’s suggestion that because the Modelling Study was submitted in support for an application for a development approval to Parkland County it is not material and relevant to the issues raised in the proceeding and is outside of the Commission’s jurisdiction. The Commission considers that the adequacy of the Modelling Study, including the information that is the subject of the above-reference information request, may be relevant to issues raised in the proceeding. Based on the foregoing, the Commission is of the opinion that the adequacy of TAMA Power’s Modelling Study may be tested by the Cymbaluks, or any other party to the proceeding including the Gunn Métis, during the oral hearing.

12. Given the date of this ruling the intervener deadline for filing evidence shall be extended as initially requested by the Cymbaluks. The Commission finds that a slight amendment to the process schedule will not prejudice any party. Accordingly, the Commission has amended the process schedule set out in its notice of hearing. An amended notice of hearing is attached hereto.

To: Interested Parties

Proceeding: 3183
Application: 1610492
Process to consider
1. In this ruling the Alberta Utilities Commission must determine whether to admit a report
by FDI Acoustics Inc. (the FDI report) as evidence in the above-referenced proceeding
notwithstanding that the deadline for intervener evidence has past.
2. The Commission has instructed me to communicate its decision and its reasons to
interested parties.
Background
3. On March 16, 2015, David Cymbaluk, Ferne Cymbaluk, and Philip Cymbaluk (the
Cymbaluks) filed a motion to admit further intervener evidence, namely the FDI report, after the
deadline for filing submissions set out in the Commission’s notice of hearing had past. The
request was made pursuant to Rule 001: Rules of Practice.
4. The Cymbaluks submitted that the FDI report related to noise modelling, that it was filed
as soon as it became available, and that they had given notice in their submissions that such
information was to be filed.
5. The Commission afforded the applicant and any other party adverse in interest to the
Cymbaluks an opportunity to respond by March 19, 2015. The Commission received comments
from the applicant and the Gunn Métis Local 55 indicating that they did not object to the
late-filed report being admitted as evidence.
How the Commission considered the motion
6. The test established by the Alberta Court of Appeal that is generally applied to determine
whether fresh evidence should be admitted is whether:
1. the evidence could not have been obtained for use at trial even with the exercise
of reasonable diligence; and
2. the evidence, if introduced, would be practically conclusive.1

[1980] 1 S.C.R. 759. Gorrie v. Nielsen, Alberta Public School Boards' Assn. v. Alberta (A.G.), 1998 ABCA 94
at paragraph 28.

7. The Court of Appeal recognized that the “two-part test is nothing more than a general
rule. On occasion, this court has seen fit to adopt a more flexible approach to the admission of
fresh evidence, even if that evidence is not practically conclusive.”2
8. Further, the Supreme Court of Canada in R. v. Palmer, held that “the [new] evidence
must be relevant in the sense that it bears upon a decisive or potentially decisive issue in the
trial” and “it must be such that if believed it could reasonably, when taken with the other
evidence adduced at trial, be expected to have affected the result.”3
9. Pursuant to Section 27.2 of Rule 001, the Commission may grant a request for the late
filing of evidence “on any terms that the Commission considers appropriate”.
Commission ruling
10. As a preliminary matter, the Commission waives the requirement for an affidavit to
accompany the motion pursuant to Section 7 of Rule 001.
11. As a general rule relevant evidence should be brought forward in accordance with the
prehearing schedule established for proceedings. Following the procedure maximizes fairness to
all parties, ensures maximum efficiency of the hearing, and generally makes it easier for the
Commission to fulfill its responsibilities.
12. The Commission has considered the submissions of the parties in relation to the
Cymbaluks’ motion filed under Rule 001, the jurisprudence applicable to the introduction of new
or fresh evidence, and its discretionary authority to grant a request for the late filing of such
evidence.
13. In this case, the Commission has decided to admit the report as evidence in
Proceeding 3183. In making its ruling, the Commission considers that no party objected to the
report being filed as evidence and that the report is relevant to the issues raised in the proceeding
and could affect the result.
14. If you have any questions, please feel free to contact the undersigned at 403-592-4499 or
Yours truly,
Shanelle Sinclair

Undertaking 19 - TAMA Power, through counsel, undertook to advise the Commission on the status of the “pond” identified at ex. 0001.00Tamapowe-3183, pdf 23, figure 15.3. Early artist renderings of the project showed a proposed pond to the east of the facility (see ex. 3181-X0090, pdf. 48 and 51). As the plant design progressed the proposed pond was deemed unnecessary. TAMA Power notes that, as part of its Industrial Approval Application Alberta Environment and Sustainable Resources Development may direct TAMA Power to construct a storm water pond at the facility. If so directed, TAMA Power would construct the storm water pond likely to the west of the facility between the plant site and the existing Sundance cooling pond.
