Glossary

Ambient Sound Level or Ambient Noise

All-encompassing sound that is associated with a given environment, usually a composite of sounds from many sources near and far. Includes noise from all sources other than the sources of interest (i.e., sound other than that being measured), such as sound from other industrial sources, transportation sources, animals and nature.

A-Weighting The weighting network used to account for changes in level sensitivity as a function of frequency. The A-weighting network de-emphasizes the low (i.e., below 1 kHz) frequencies, and emphasizes the frequencies between 1 kHz and 6.3 kHz, in an effort to simulate the relative response of the human ear. See also frequency weighting.

Background Sound Level or Background Noise

Same as the ambient sound level.

Daytime (Operations Noise Assessment)

Defined as the hours from 07:00h to 19:00h in Ontario.

Daytime (Operations Cumulative Noise Assessment)

Defined as the hours from 07:00h to 23:00h for Health Canada calculation of %HA.

Decibel A logarithmic measure of any measured physical quantity and commonly used in the measurement of sound. The decibel (dB) provides the possibility of representing a large span of signal levels in a simple manner. The difference between the sound pressure for silenced versus a loud sound is a factor of 1:1,000,000 or more and the same in Decibel is 0-130 dB, therefore it is less cumbersome to use a small range of equivalent values. A tenfold increase in sound power is equal to +10 dB; a tenfold increase in sound amplitude is equal to +20 dB.

Decibel, A-weighted A-weighted decibels (dBA). Most common units for expressing sound levels since they approximate the response of the human ear.

Energy Equivalent Sound Level (Leq)

An energy-equivalent sound level (Leq) over a specified period of time that would have the same sound energy as the actual (i.e., unsteady) time varying sound over the same period of time. It represents the average sound pressure encountered for the period. The period is often added as a suffix to the label (i.e., Leq(24) for the 24-hour


vi

equivalent sound level). A Leq value expressed in dBA is a good, single-value descriptor to use as a measure of annoyance due to noise.

Evening (Operations Noise Assessment)

Defined as the hours from 19:00h to 23:00h in Ontario.

Frequency The number of times per second that the sine wave of sound repeats itself. It can be expressed in cycles per second, or Hertz (Hz).

Frequency Weighting A method used to account for changes in sensitivity as a function of frequency. Three standard weighting networks, A, B, and C, are used to account for different responses to sound pressure levels. Note: The absence of frequency weighting is referred to as “flat” response or linear weighting. See also A-weighting.

Ground Absorption Coefficient A parameter defined based on noise reflection characteristics of a surface. It varies between 0.0 (fully reflective) to 1.0 (fully absorptive).

Hertz (Hz) The unit of frequency also expressed as cycles per second.

International Organization for Standardization

An international body that provides scientific standards and guidelines related to various technical subjects and disciplines.

Line Source Multiple point sources moving in one direction (e.g., a continuous stream of roadway traffic, radiating sound cylindrically). Sound levels from a line source decrease at an ideal rate of 3 dB per doubling of distance.

Mitigation Measures taken to reduce, eliminate, or control impacts on the environment.

Nighttime (Operations Noise Assessment and Operations Noise Cumulative Assessment)

Defined as the hours from 23:00h to 07:00h in Ontario

Noise Any unwanted sound. “Noise” and “sound” are used interchangeably in this document.

Octave The interval between two frequencies having a ratio of two to one. For acoustic measurements, the octave bands start at 1,000 Hz centre frequency and go up or down from that point, at a 2:1 ratio. From


vii

1,000 Hz, the next centre frequency is 2,000 Hz; the next is 4,000 Hz, or 500 Hz, 250 Hz, etc.

Point of Reception A representative point considered for the purpose of assessment within noise-sensitive receptor such as a residence, campground, daycare, school, church, or hospital.

Point Source Source that radiates sound spherically (i.e., equally in all directions). Sound levels from a point source decrease at a theoretical rate of 6 dB per doubling of distance.

Predictable Worst-Case Operation

A planned and predictable mode of operation for stationary source(s), during the hour when the noise emissions from the stationary source(s) have the greatest impact at a point of reception, relative to the applicable limit.

Sound A wave motion in air, water, or other media. It is the rapid oscillatory compression changes in a medium that propagate to distant points. It is characterized by changes in density, pressure, motion, and temperature as well as other physical properties. Not all rapid changes in the medium are due to sound (e.g., wind distortion on a microphone diaphragm).

Sound Level Generally, sound level refers to the weighted sound pressure level obtained by frequency weighting, usually A- or C-weighted, and expressed in decibels

Sound level meter An instrument consisting of a microphone, amplifier, output meter and frequency-weighting networks that is used to measure noise and sound levels.

Sound Power Level The total sound energy radiated by a source per unit time (i.e., rate of acoustical energy radiation). The unit of measurement is the Watt. The acoustic power radiated from a given sound source as related to a reference power level (i.e., typically 1E-12 watts, or 1 picowatt) and expressed as decibels. A sound power level of 1 watt = 120 decibels relative to a reference level of 1 picowatt.

Sound Pressure The root-mean-square of the instantaneous sound pressures during a specified time interval in a stated frequency band.


viii

Sound Pressure Level Logarithmic ratio of the root mean square sound pressure to the sound pressure at the threshold of human hearing (i.e., 20 micropascals).

Spectrum (Frequency Spectrum) The frequency dependent characteristic of sound often expressed as amplitude versus octave band frequency (see octave band).


Introduction July 2021

1.1

1.0 INTRODUCTION

Enbridge Pipelines Inc. on behalf of Westover Express Pipelines Ltd (Enbridge) is applying to the Canada Energy Regulator (CER) under section 214 of the Canadian Energy Regulator Act (CER Act) for approval to construct and operate the Westover Facility Project (the Project) and Line 101, under the oversight of the CER, until at least April 2023. Enbridge is also applying under section 45(1) of the CER Onshore Pipeline Regulations (OPR) for certain decommissioning activities associated with the Project.

The Project includes construction of a new custody transfer meter including a prover, instrument shelter, lab, electrical building, and booster pumps for Line 10 inside the existing Westover Terminal. The Project also includes grading, civil work, fencing and new infrastructure (a new electrical switchgear building and cable trays) adjacent to the existing Westover Terminal, and electrical work to share the existing substation at the Westover Terminal. The Project also includes a new electrical building and civil work (including delineation berms and grading) inside the existing Nanticoke Junction valve site (Nanticoke VS), as well as construction of electrical connections, including a below grade connection to the hydro-electric grid, located outside and adjacent to the Nanticoke VS fenceline. The Project will also include decommissioning of three existing booster pumps at the Westover Terminal. The Project will not require any new land or new road access.

Stantec Consulting Ltd. (Stantec) was retained by Enbridge to complete a noise technical data report (TDR) in support of the Environmental and Socio-economic Assessment (ESA) for the Project. This TDR provides a noise impact assessment of the Project in line with the filing requirements outlined in the CER Filing Manual (CER 2020). In accordance with the CER Filing Manual, this TDR provides a noise impact assessment of Project construction and operations with respect to the following provincial noise guideline and federal noise guidance:

• The Ontario Ministry of the Environment, Conservation and Parks (MECP) NPC-300 – Environmental Noise Guideline (MECP 2013)

• Health Canada (HC) Guidance for Evaluating Human Health Impacts in Environmental Assessment: Noise (Health Canada 2017)

This TDR also provides the basis for the Acoustic Environment assessment presented in Section 12.0 of the ESA.

Only Project components that have the potential to notably change the acoustic environment are considered in this TDR. These Project components are located within and adjacent to the existing Westover Terminal, and consist of the following equipment and buildings:

• Two (2) new 400 horsepower (HP) booster pumps (to replace the three existing 100 HP booster pumps)

1 The Line 10 pipeline currently transports crude oil from the Westover Terminal to the United Refining Company (United) Kiantone Pipeline in West Seneca, New York.


Introduction July 2021

1.2

• New Instrument Shelter Building (510-ISH-1)

• New Electrical Building (151-EB-1)

• New Lab Building (510-BLDG-1)

• New Electrical Switchgear Building (10-ESB-2)

• New Transformer (10-TX-3)

• Relocation of existing generator (10-G-1)

Although the Nanticoke VS also includes the addition of a new electrical building, noise generated to the outdoors is expected to come from a single pressurization fan. This fan is planned to be within the Nanticoke VS fence line and therefore, located more than 180 m from the nearest noise sensitive residence. At this setback distance, noise from the single pressurization fan, with the specifications provided by Enbridge, will meet the applicable noise criteria used in this TDR. On this basis, the Nanticoke VS is not assessed further in this TDR.

1.1 OBJECTIVE

The objective of this TDR is to assess the noise impact during Project construction and operations using applicable guidelines and sound level limits. If the predicted sound levels from the Project exceed the applicable sound level limits, then mitigation measures expected to result in compliance with these limits are recommended.


Assessment Area July 2021

2.1

2.0 ASSESSMENT AREA

The existing Enbridge Westover Terminal property is located at 1430 and 1442 Concession 6 West in Hamilton, Ontario. The area surrounding the existing Westover Terminal is zoned as Rural (A2), Conservation/Hazard Land (P#) and Settlement Residential (S#) under the City of Hamilton Comprehensive Zoning By-law No. 05-200 (The City of Hamilton 2019).

For the purposes of this TDR, the following spatial boundaries are used to define the assessment area:

• Project Development Area (PDA): The PDA encompasses the expected area of physical disturbance associated with the construction and operation of the Project.

• Local Assessment Area (LAA): The LAA includes the area within which Project-related noise effects are predicted to occur and is defined using an up to 1000 m buffer applied to the PDA. The Project must operate in compliance with applicable sound level limits in the LAA. The LAA is the area which includes the Points of Reception.

• Regional Assessment Area (RAA): The RAA is the same as the LAA.

The PDA and LAA are shown in relation to the existing Enbridge Westover Terminal in Appendix A-Figure 1.


Points of Reception July 2021

3.1

3.0 POINTS OF RECEPTION

This TDR assesses operations-related noise impacts at Points of Reception (PORs). PORs are locations on noise sensitive land uses2 where operations-related noise is received. Eight PORs were identified for the noise impact assessment using publicly available aerial imagery and local land-use zoning maps of the LAA. These PORs are expected to experience the highest operation-related sound levels because of their proximity to the PDA, and are therefore representative of the highest noise impact for the closest PORs to the Project. Other nearby PORs are expected to experience a lesser noise impact due to increased distances from the PDA, and noise shielding from intervening buildings and topography. The representative PORs are listed in Table 3.1 and shown in relation to the PDA in Appendix A – Figure 1.

The Ontario MECP NPC-300–Environmental Noise Guideline (MECP 2013) defines two types of POR for residential land uses: plane of window POR and outdoor POR. The physical location of the plane of window POR is at the centre of a window at the height of the most-exposed storey. Generally, the plane of window POR height is at minimum 1.5 m above ground for the first storey plus 3.0 m for each subsequent storey. The physical location of the outdoor POR is anywhere within 30 m of the dwelling façade typically in backyard, front yards, terraces or patios, at a height of 1.5 m above ground.

Environmental Noise Descriptors July 2021

4.1

4.0 ENVIRONMENTAL NOISE DESCRIPTORS

Environmental noise is typically not steady. To account for the time-varying nature of environmental noise, a single number descriptor known as the continuous equivalent sound level (Leq) is used. It is defined as a steady continuous sound level over a specified time interval that has the same acoustic energy as the original time-varying sound.

The decibel is a unit of measure of sound pressure that compresses a large range of numbers into a more meaningful scale. Hearing tests indicate that the lowest audible pressure is about 2 x 10-5 Pa (0 dB), while the sensation of pain is about 2 x 102 Pa (140 dB).

The recorded sound can be “frequency-weighted” with A being the most common. The corresponding weighted Leq values would then be expressed in A-weighted decibels (dBA). The A-weighted scale is based on relative loudness of sound at different frequencies and is meant to reflect the human ear response to noise. The decibel level (dB) does not have any frequency weighting and can be used when referring to differences in weightings.

A-weighted Leq are commonly used as environmental noise descriptors in regulatory guidelines and guidance. Time periods used in Ontario regulatory criteria for Leq are daytime (07:00 to 19:00), evening (19:00 to 23:00) and nighttime (23:00 to 07:00). Where evening time periods are not relevant, the daytime sound level (Ld) is A-weighted Leq established for the entire 16-hour daytime/evening period (i.e., 07:00 to 23:00). The nighttime sound level (Ln) is the A-weighted Leq established for the entire 8-hour nighttime period. The day-night equivalent sound level (Ldn) is a 24-hour time-averaged Leq, which includes a +10 decibel (dB) adjustment during the nighttime as a penalty for sounds occurring during the nighttime period.


Regulatory Framework July 2021

5.1

5.0 REGULATORY FRAMEWORK

The Filing Manual (CER 2020) refers to the provincial noise guideline and federal noise guidance for quantitative sound level limits. The following sections provide details for the provincial and federal regulatory framework that provides quantitative sound level limits.

5.1 PROVINCIAL NOISE GUIDELINE

5.1.1 Construction-related Noise

MECP publications NPC-115 (MECP 1977) and NPC-118 (MECP 1982), provide sound level limits applicable to construction activities. These publications stipulate sound level limits on individual pieces of equipment rather than receptor specific sound level limits. A summary of the construction equipment sound level limits is provided in Table 5.1.

Table 5.1 MECP NPC-115 and NPC-118 Noise Emission Limits

Type of Equipment Maximum Sound Level (dBA) Excavation equipment, bulldozers, loaders, backhoes or other equipment or other equipment capable of being used for a similar application 1

83 (for Power Rating less than 75 kW)

85 (for Power Rating 75 kW and greater)

Pneumatic Pavement Breakers 2 85

Portable Air Compressors 3 76

Track Drills 1 100

Heavy Vehicle with Governed Diesel Engines 3 95

NOTES: 1 Maximum Sound Level (dBA) determined per Publication NPC-103 - Procedures, Section 6. 2 Maximum Sound Level (dBA) determined per Publication NPC-103 - Procedures, Section 7. 3 Maximum Sound Level (dBA) determined per Publication NPC-103 - Procedures, Section 9.

5.1.2 Operations-related Noise

MECP NPC-300 provides sound level limits applicable to Project operations. These sound level limits are defined at the POR and are applicable to stationary sources3. The sound level limits are given in terms of the A-weighted one-hour equivalent sound level (Leq-1hr) and vary depending on the local acoustic environment, the time of day and the type of POR (i.e., Plane of Window POR or Outdoor POR). These are referred to as the MECP exclusionary sound level limits.

3 NPC-300 broadly defines a Stationary Source as a source of sound or combination of sources of sound that are included and normally operated within the property lines of a facility.



5.2

The PORs identified in Table 3.1 are located in a rural area where the local acoustic environment is consistent with an MECP Class 3 area. An MECP Class 3 area has an acoustical environment that is dominated by natural sounds having little or no road traffic. A summary of the MECP exclusionary sound level limits for Class 3 areas is provided Table 5.2.

In accordance with MECP NPC-300, noise emissions from the non-emergency operation of emergency equipment (e.g., testing of emergency generators), are assessed separately using sound level limits that are 5 dB greater than those otherwise applicable to stationary sources. A summary of the applicable sound level limits of for the non-emergency operation of emergency equipment is provided in Table 5.3. There is no quantitative sound level limit for emergency operations in Ontario.

MECP NPC-300 indicates that the acoustic assessment of stationary noise impacts at a POR must address the predictable worst-case noise impact. The predictable worst-case noise impact means the noise impact associated with a planned and predictable mode of operation for stationary source(s), during the hour when noise emissions from the stationary source(s) have the greatest impact at the POR, relative to the applicable limit.

Where the predicted Leq-1hr exceeds the sound level limits in Table 5.2 for Project operations or the sound level limits in Table 5.3 for non-emergency operation of emergency equipment, noise mitigation measures are recommended to bring the sound levels into compliance with those limits.

5.2 FEDERAL NOISE GUIDANCE

5.2.1 Operations-related Noise

The HC Guidance for Evaluating Human Health Impacts in Environmental Assessment (HC Guidance; Health Canada 2017) provides a noise assessment metric applicable to Project operations. The HC Guidance uses the change in percentage of highly annoyed (%HA) metric as an indicator of noise-induced human health effects from exposure to project operational noise. The change in %HA is calculated as the difference between %HA associated with Project operations and the %HA associated with existing baseline sound level (i.e., existing acoustic environment).

The %HA is calculated using the following equation:

%HA=100/[1+exp(10.4-.132*LRdn)

where,

LRdn = day-night rating level



5.4

The LRdn is obtained by applying the applicable source-based or receptor-based adjustments given in the HC Guidance to the day-night sound level (Ldn).

The HC Guidance indicates that noise mitigation measures should be considered when the calculated increase in %HA over baseline, at any POR, is 6.5% or greater. HC Guidance also recommends mitigation if the Ldn from Project operations exceeds 75 dBA, even if the change in %HA does not exceed 6.5%.


Assessment Approach and Methods July 2021

6.1

6.0 ASSESSMENT APPROACH AND METHODS

Noise emissions associated with Project construction are expected to be transient and occur only for a short time (expected to commence in late February or March 2022 and completed in October 2022). Therefore, a receptor-based assessment of construction-related noise is not included for the Project. Instead, construction-related noise will be addressed by applying the standard mitigation measures in Enbridge’s Environmental Protection Plan (EPP; see Environmental and Socio-Economic Assessment), and by adhering to the MECP construction equipment noise emission limits published in NPC-115 and NPC-118.

Noise emissions associated with Project operations will be long-term (approximately 25 years or more). Therefore, the following operations-related scenarios were assessed:

1. Project Sound Level – Combined sound level of Project noise sources and the existing Westover Terminal at the PORs is assessed against the applicable MECP NPC-300 sound level limits. This scenario includes the noise assessment of emergency equipment testing.

2. Cumulative Sound Level – Combined sound level of Project noise sources and the existing baseline sound level at the PORs is assessed against the change in %HA threshold provided in the HC Guidance.

The following sections provide details on the assessment approach and methods for the above two operations-related scenarios.

6.1 PROJECT SOUND LEVEL

The approach to assess the Project Sound Level involved the following steps:

1. Predict sound levels at the PORs (from Table 3.1) from the Project sources using a predictive acoustic model (see section 6.4).

2. Obtain sound levels at the PORs from the existing Westover Terminal from an independent acoustic assessment report (Dillon Consulting Ltd. 2020) attached as Appendix B. This independent acoustic assessment report (AAR) was prepared as part of the documentation requirements of the Ontario Environmental Compliance Approval for the existing Westover Terminal.

3. Combine the predicted sound levels from steps 1 and 2, and compare the result to the applicable MECP NPC-300 sound level limits in Table 5.2.

4. If the predicted sound levels exceed the applicable sound level limits, recommend mitigation measures to bring the sound levels into compliance with those limits.



6.2

6.2 CUMULATIVE SOUND LEVEL

The approach to assess the cumulative noise from Project noise sources and the existing baseline sound level involved the following steps:

1. Establish a representative baseline Ldn using sound level data measured as part of the Baseline Sound Level Study (see section 6.3).

2. Calculate the %HA associated with the representative baseline Ldn.

3. Calculate the %HA associated with the existing and Project Ldn and the representative baseline Ldn at the PORs. The Project Ldn was determined using a predictive acoustic model (see section 6.4).

4. Calculate the difference between the Project %HA and the representative baseline %HA at the PORs.

5. If the difference in the Project %HA over baseline is greater than +6.5%, recommend mitigation measures that result %HA being less than +6.5%.

6.3 BASELINE SOUND LEVEL STUDY

Stantec conducted a Baseline Sound Level Study to quantify existing baseline sound levels (in terms of Leq-1hr and Ldn) within the LAA. Baseline sound levels were measured continuously (noise monitoring) at four locations surrounding the existing Westover Terminal between December 3, 2020 and December 8, 2020. The monitoring locations are listed in Table 6.1 and are shown in relation to the Westover Terminal in Appendix A – Figure 1.

The baseline sound levels measured at the monitoring locations will have different degrees of influence from existing Westover Terminal noise and local road traffic noise. The degree of influence from these noise sources depends largely on setback distance. Monitoring locations closer to the existing Westover facility will have a greater sound level contribution from the facility than those farther away. The same is true with respect to local road traffic.

Stantec conducted noise monitoring in accordance with the applicable NPC-103 guidelines (MECP 1978a) using sound level meters (SLMs) conforming with IEC 61672-2002 Class 1 Instrument criteria (International Electrotechnical Commission 2002). A summary of the noise monitoring instrumentation used is provided in Table 6.2. All monitoring instrumentation used was factory calibrated within one year of the monitoring period start date; factory calibration certificates are available upon request. Each SLM was also field calibrated using an acoustical calibrator before and after the monitoring period.

Measured sound levels that may have been affected by inclement weather, as defined in NPC-103, were removed from the baseline sound level analysis. Inclement weather periods during the monitoring period were identified through a review of historical weather data obtained from the nearest Government of Canada weather station. Historical weather data for the monitoring period is provided in Appendix C.

The SLMs were configured to collect energy equivalent continuous sound levels (Leq), maximum sound levels (Lmax), and minimum sound levels (Lmin) in 5-minute intervals.



6.3

Each SLM was installed at a height of 1.5 m above ground and equipped with weatherproof enclosures, and windscreens suitable for outdoor noise monitoring.

6.4 ACOUSTIC MODELLING

To predict Project Sound Levels (Leq-1hr and Ldn), a predictive acoustical model was generated using the commercially available software package CADNA/A, published by Datakustik GmbH. The acoustic model was set up to implement environmental noise propagation algorithms established in ISO 9613-1 and 9613-2 (IOS 1996a; 1996b). In accordance with these ISO algorithms, the acoustic model accounts for the following:

• Geometrical divergence (noise attenuation due to distance)

• Noise shielding from intervening structures/buildings

• Atmospheric absorption

• Ground effects

• Local topography



6.4

The acoustic model considers a downwind condition, in which for the purpose of analysis, the wind direction is always oriented from each source location towards each POR location. Key acoustic model parameters are provided in Table 6.3.

Parameter Value Rationale Ground Absorption 0.2 Accounts for mostly acoustically reflective surfaces (pavement and

hard packed ground) within the PDA

Ground Absorption 0.8 Accounts for mostly acoustically absorptive (i.e., grass) surfaces outside the PDA and near the PORs

7.0 PROJECT NOISE EMISSIONS

7.1 PROJECT SOURCES

Project sources include the following pieces of equipment:

• One (1) Booster Pump

• One (1) Transformer

• One (1) Makeup Air Unit

• Five (5) Air Conditioners

• Six (6) Building Exhaust Fans

• One (1) Relocated Emergency Generator

For the purposes of this TDR, these Project sources are conservatively considered to be operating 24 hours per day and 7 days per week.

Although there will be two new booster pumps installed at the Westover Terminal, Enbridge indicated that only one pump will be operating; the other pump will be a spare. Therefore, only the booster pump (tag no. 201-BP13) generating the highest sound levels at the PORs was modelled.

The Project source sound power levels were used as inputs into the acoustic model and are summarized in Table 7.1. The sound power levels were estimated using engineering prediction methods (Hansen 2003) (VIbro-Acoustics 2011) supplemented with manufacturer data supplied by Enbridge. Spectral data for the sound power levels are provided in Appendix D.

MECP publication NPC-104 (MECP 1978b) prescribes adjustments for sources with special qualities or characters of sound. These are punitive adjustments which apply to noise sources with subjectively annoying characteristics, including tonal sounds, quasi-impulsive sounds and beating sounds (sounds with cyclically varying amplitudes). For the Project sources, only the transformer is expected to exhibit a tonal characteristic; therefore, a +5dB penalty was applied to its sound power level.

A map showing the Project sources in relation to the PDA is provided in Appendix A – Figure 2.

8.0 RESULTS

8.1 BASELINE SOUND LEVEL

The collected baseline sound level data at each monitoring located was analyzed to obtain the distribution of Leq-1hr during the daytime, evening and nighttime periods. Leq-1hr is the relevant metric for noise impact assessment under MECP NPC-300. A summary of the number of collected and valid measurement hours is provided in Table 8.1. A summary of the calculated Leq-1hr from the valid measurement hours is provided in Table 8.2.

MECP NPC-300 indicates that the higher of either the minimum measured background sound level4 or the applicable exclusionary sound level limit can be used for the noise impact assessment. The minimum measured Leq-1hr (see Table 8.2) include some contribution from the existing Westover Terminal, and are therefore higher than the actual background sound level due to Westover Terminal noise. Despite including some contribution from the existing Westover Terminal, measured levels were less than the applicable MECP exclusionary sound level limit for all time periods, and at all monitoring locations. Therefore, it is appropriate to use the applicable MECP exclusionary limits for the Project Sound Level assessment.

The measured Leq-1hr were subsequently used to calculate the baseline Ldn at each monitoring location, as well as the corresponding baseline %HA. Measurement location M02 was found to have the lowest baseline %HA and is therefore used to represent the baseline %HA conditions at all PORs. All else being equal, using a lower baseline %HA results in a higher and more conservative change in %HA. In addition, the baseline %HA includes a conservative +10dB adjustment to account for the greater expectation for “piece and quiet” in quiet rural areas. Based on observations on site, the acoustic environment is typical of a rural area.

A summary of the calculated baseline Ldn and %HA is provided in Table 8.2. Ldn and %HA are the relevant metrics for the assessment of cumulative noise from new noise sources and the existing baseline sound level.

4 Background sound level is the sound level that is present in the environment, produced by noise sources other than the source under impact assessment.

8.2 PROJECT SOUND LEVEL

The Project Sound Levels were predicted at the PORs and are summarized in Table 8.4. The results in Table 8.4 show that the predicted Project Sound Levels at the PORs are less than or equal to the applicable MECP exclusionary sound level limits. Therefore, the Project Sound Levels at the PORs are predicted to be in compliance with the applicable MECP exclusionary sound level limits. A summary of the overall sound level contributions from Project sources and the existing Westover Terminal is provided in Appendix E.

The sound levels for emergency equipment testing were predicted at the PORs and reflect the relocated emergency generator (10-G-1); the results are summarized in Table 8.5. The results in Table 8.5 show that the predicted sound levels from emergency equipment testing are less than the applicable MECP exclusionary sound level limits. Therefore, the predicted sound levels for emergency equipment testing are in compliance with the applicable MECP exclusionary sound level limits for emergency equipment testing. A summary of the overall sound level contributions from Project sources and the existing emergency equipment from the Westover Terminal is provided in Appendix E.

8.3 CUMULATIVE SOUND LEVEL

The changes in %HA were predicted at the PORs and are summarized in Table 8.6. The results in Table 8.6 show that the predicted change in %HA over baseline is less than 6.5% at all PORs. Therefore, the cumulative sound levels at the PORs are in compliance with the HC guidance for the change in %HA threshold for Project operations.

The predicted change in %HA is based on the %HA baseline determined for monitoring location M02 (Table 8.3). The %HA baseline for M02 is the lowest amongst the baseline monitoring locations and therefore, results in the highest change in %HA. In other words, using the lowest calculated %HA baseline results in a conservative impact assessment with all else being equal. Additionally, the %HA Project was based on the Project sources, including emergency equipment, operating continuously throughout the daytime and nighttime. This also results in a conservative impact assessment with respect to the change in %HA. Supporting calculations for the Cumulative Sound Level assessment are provided in Appendix F.

The Cumulative Sound Levels at all PORs are below 75 dBA and are therefore in compliance with HC guidance for Cumulative Sound Level.

Summary of Findings and Conclusions July 2021

9.1

9.0 SUMMARY OF FINDINGS AND CONCLUSIONS

A noise impact assessment was completed for Project construction and operations.

Construction-related noise will be addressed by applying the standard mitigation measures in Enbridge’s Environmental Protection Plan, and by adhering to the MECP construction equipment noise emission limits published in NPC-115 and NPC-118.

The results of the noise impact assessment Project operations showed that both the Project Sound Level and the Cumulative Sound Level meet the applicable MECP NPC-300 sound level limits and applicable HC Guidance thresholds, respectively.

1.0 Introduc on

1.1 Purpose and Objec ves Dillon Consulting Limited (Dillon) was retained by Enbridge Pipeline Inc. (Enbridge) to prepare anAcoustic Assessment Report (AAR) for the Enbridge Westover Terminal (Facility) located at 1430 6th

Concession Road West, in Branchton, Town of Flamborough, Hamilton, Ontario. This updated report isbeing submitted to the Ontario Ministry of Environment, Conservation and Parks (MECP) in support ofan annual written summary for the Facility.

The purpose of this assessment is to evaluate the overall noise emissions from the Facility under arealistic worst-case operating scenario and determine the associated noise impacts at the nearbyreceptors. The Facility is not a significant source of vibration, therefore a vibration assessment is notwarranted.

An AAR, dated July 6, 2016 was prepared for the Facility by Novus Environmental Inc. (Novus), andsubmitted to the MECP as part of an amendment to Air and Noise Environmental Compliance Approval(ECA) No. 6878-AAWJ6W. A copy of the AAR is provided in Appendix A.

The Facility is located in an area zoned “Existing Rural Commercial”. Four (4) representative receptorlocations have been identified in the areas surrounding the Facility.

This AAR has been prepared in accordance with the relevant MECP noise publications, including NPC-233 and NPC-300 and is submitted to the MECP in support of an annual written summary for the Facility.

1.2 Overview of FacilityThe Westover Terminal stores and transports crude oil product. The Facility has eight crude oil storagetanks, six of which are external floating roof and two are domed external floating roof. The Facility alsohas three pipeline inspection gauge (PIG) traps / launchers and three underground sump tanks fortemporary storage of crude oil. Regular operations at the Facility occur 24 hours per day, seven days perweek.

The primary noise sources of concern related to the Facility’s regular operations include; vacuum trucksused for PIG launch and receipt, mainline pumps, and welding exhaust. The Facility also has emergencyequipment that has the potential to cause noise impacts. The emergency equipment is discussed furtherin Section 2.2.2.

As per City of Hamilton Zoning By-law No. 05-200, the Facility is in an area zoned E1 “Existing RuralCommercial”. To the north of the Facility, is Westover Community Park which is equipped with a sports

field and outdoor amenities. Surrounding the site are lands zoned A2 “Rural” and P7/P8“Conservation/hazard Land”. The zoning plan for the site and surrounding area is provided in AppendixB.

1.3 Summary of Acous c Environment and Applicable Noise Limits The background ambient noise, exclusive of that generated by the Facility can be characterized ashaving qualities of a Class 3 (rural) area, as described in NPC-300. The primary contributors to thebackground sound are natural sounds and minor amounts of road traffic noise.

1.4 Statement of Compliance This study confirms that the Facility complies with the daytime, evening, and nighttime noise guidelinelimits defined in the MECP’s NPC-300, for all sources assessed in this report.

2.0 Facility Descrip on The Westover Terminal is a storage terminal for crude oil product. The Facility has eight crude oilstorage tanks, six of which are external floating roof and two are domed external floating roof. TheFacility also has three Pipeline Inspection Gauge (PIG) traps / launchers and three underground sumptanks for temporary storage of crude oil. Regular operations at the Facility occur 24 hours per day, sevendays per week.

The primary noise sources of concern related to the Facility’s regular operations include; vacuum trucksused for PIG launch and receipt, mainline pumps, and welding exhaust. The Facility also has three (3)emergency generators and a fire water pump, which are tested on a monthly basis in accordance withthe TSSA requirements. The testing of the emergency equipment has the potential to impact the noiseenvironment at the nearby receptors. The emergency equipment is discussed further in sub-section2.2.2.

The dominant noise genera ng sources and opera ons at the Facility are listed in Table 1.

2.1 Noise Source Types The significant noise sources and operations that were identified as part of this study are summarized inTable 1.

2.2 Opera ons

. . Regular Opera ons

Regular operations at the Facility occur 24 hours per day, seven days per week. The only exception tothis is the operation of vacuum trucks as part of PIG operations, which only occur during daytime hours.However, in rare instances the vacuum truck operations must occur during evening or nighttime hours.These occurrences are infrequent and as such, vacuum truck operations were solely assessed fordaytime impacts. There are four possible vacuum truck locations at Westover Terminal and only one ofthese locations will be in operation at any given time as indicated in Table 1. All four locations wereassessed for noise impacts on the nearby receptors and the worst-case vacuum truck location wasdetermined. This location (source ID: PT07) was used to determine the worst-case operating scenario forthe Facility. For the purposes of this assessment it is conservatively assumed that all dominant noisesources (excluding emergency equipment) at the Facility are operating continuously and simultaneously.

. . Emergency Equipment Tes ng

The Facility has three (3) emergency generators, two (2) portable generators, and one (1) fire waterpump. The testing of the emergency equipment can take up to 20 minutes per piece of equipment andthe testing does not typically occur simultaneously. However, for the purposes of this assessment, it wasconservatively assumed that all emergency equipment are tested simultaneously and continuously foran entire hour. The testing of emergency equipment typically occurs during daytime hours, however, forthe purposes of this assessment, the predicted noise impacts were also compared against the eveningand nighttime limits as well. As per NPC-300, the noise impact from testing of the emergency equipmentwas assessed independently of the regular operations, and against exclusionary limits that are 5 dBgreater than the applicable MECP criteria.

Notes:[4] PT07 represents the worst-case location for noise impacts from vacuum truck operations on the nearby sensitivereceptors. Since only one vacuum truck can be in operation at any given time, this location was used for theassessment.[5] The vacuum truck locations with source iDs PT07_sump, PT10_relocated, and PT11 do not represent the worst-caselocation for noise impacts from vacuum truck operations. Therefore, these locations were not assessed further astheir respective noise impacts will be less than those from PT07.

No additional noise sources have been added to the Facility since the previously approved AAR.

The vacuum truck operations, used for PIG launch and receipt, typically run at an idle or low speed.Based on the operating conditions of the vacuum truck, observations outlined in the previouslyapproved AAR, and review of the vacuum truck spectral data, the vacuum truck is not considered to be atonal source. Therefore, no tonal penalty was applied.

The Facility has occasional construction, maintenance, and repair activities that occur throughout theFacility, which include the use of impact wrenches, portable welding, and small portable generators.These activities are temporary in nature and as per NPC-300, they have not been included in thisassessment.

4.0 Point of Reception Noise Impact Analysis 6


Additionally, approximately once per quarter the facility conducts biocide injections. This includes theuse of a portable compressor for up to 30 minutes. As per NPC-300, this activity is considered to be aninfrequent operation of equipment and has not been included in this assessment.

3.2 Background Noise The Facility is surrounded by a mix of agricultural fields, woodlands, and a community park to the north.Low volumes of road traffic are expected near the Facility and therefore, the areas surrounding the sitecan be best described as Class 3, as defined in MECP’s NPC-300.

3.3 Noise Control Equipment and Acous cal Specifica ons The firewater pump (source ID: Fire_CombEx+Vent) is equipped with a silencer and the emergencygenerators (source IDs: 100kW, 200kW1, and 200kW2) are equipped with acoustic enclosures asindicated in Table 2. The associated sound power levels for this unit is reflective of the silencer in place.

4.2 Land Use Zoning Plan As per the City of Hamilton Zoning By-law No. 05-200, the Facility is in an area zoned E1 “Existing RuralCommercial”. To the north of the Facility, is Westover Community Park which is equipped with a sportsfield and outdoor amenities. Surrounding the site are lands zoned A2 “Rural” and P7/P8“Conservation/hazard Land”. The zoning plan for the site and surrounding area is provided inAppendix B.

4.3 Points of Recep on (PORs) List and Descrip on As per the MECP noise guideline a Point of Reception (POR) / receptor as “any location on a noisesensitive land use where noise from a stationary source is received.” Noise sensitive receptors, asdefined in MECP Publication NPC-300, include the following land uses:

· Permanent, seasonal, or rental residences;· Hotels, motels and campgrounds;· Schools, universities, libraries and daycare centres;· Hospitals and clinics, nursing / retirement homes; and



· Churches and places of worship.

Four (4) representative sensitive points of reception were identified for the purposes of this acousticassessment, as shown in Figure 3. These PORs are the closest receptors to the Site in various directions.Brief descriptions of the receptors is provided below and summarized in Table 3.

POR1 – A two-storey residential dwelling on Concession Road 6 West located approximately 410mnorthwest of the site. A receptor height of 4.5m, representing a receiver in the open plane of a second-storey window was assumed. A receptor at a height of 1.5 m (ID: POR1_O) was also assessed in the backyard of the residential dwelling, at a location closest to onsite noise sources. This receptor representsthe worst-case outdoor POR location for the dwelling and was assessed for daytime and evening impactsonly as per NPC-300.

POR2 – A two-storey residential dwelling on Concession Road 6 West located approximately 180m northof the site. A receptor height of 4.5m, representing a receiver in the open plane of a second-storeywindow was assumed. A receptor at a height of 1.5 m (ID: POR2_O) was also assessed in the front yardof the residential dwelling, at a location closest to onsite noise sources. This receptor represents theworst-case outdoor POR location for the dwelling and was assessed for daytime and evening impactsonly as per NPC-300.

POR3 – A two-storey residential dwelling on Concession Road 6 West located approximately 265mnortheast of the site. A receptor height of 4.5m, representing a receiver in the open plane of a second-storey window was assumed. A receptor at a height of 1.5 m (ID: POR3_O) was also assessed in the backyard of the residential dwelling, at a location closest to onsite noise sources. This receptor representsthe worst-case outdoor POR location for the dwelling and was assessed for daytime and evening impactsonly as per NPC-300.

POR4 – A one-storey residential dwelling on Westover Road located approximately 470m east of thesite. A receptor height of 1.5m, representing a receiver in the open plane of a first-storey window wasassumed. A receptor at a height of 1.5 m (ID: POR4_O) was also assessed in the back yard of theresidential dwelling, at a location closest to onsite noise sources. This receptor represents the worst-case outdoor POR location for the dwelling and was assessed for daytime and evening impacts only asper NPC-300.

4.4 Procedure for Assessing Noise Impacts at Each Receptor Method Selec on FactorsSound power levels for dominant on-site noise sources were used as input to the predictive computermodel CADNA/A noise prediction software developed by DataKustik GmbH. The outdoor noisepropagation model is based on ISO Standard 9613, Part 1: Calculation of the absorption of sound by theatmosphere, 1993 and Part 2: General method of calculation (ISO-9613-2:1996). The model is capable ofincorporating various site specific features, such as elevation, berms, absorptive grounds, and barriers toaccurately predict noise levels at specific receptors, pertaining to noise emissions from a particularsource / sources. The ISO based model accounts for reduction in sound level due to increased distanceand geometrical spreading, air absorption, ground attenuation, and acoustical shielding by interveningstructures and topography. The model is considered conservative as it represents atmosphericconditions that promote propagation of sound from source to receiver.

Noise Source Sound LevelOnsite noise measurements were carried out by Novus in 2014. The details of the measurements can be found in the previously approved AAR, in Appendix A.

Ambient Determina onBackground ambient sound levels were not measured at the nearest receptor loca ons. MECP’s exclusionary guideline noise criteria for a Class 3 area, as per NPC-300, where used as the performance limits for the four representa ve PORs.

4.5 Parameter / Assump ons for Calcula ons Source specific noise data was input into the CADNA/A software to model the noise impacts at theselected nearest receptors. All significant noise sources were modeled as point sources withhemispherical spreading. The following assumptions were incorporated in the modelling:



ReflectionsSources were modelled assuming a second order reflection.

Ground AbsorptionA local ground absorption coefficient of 0.50 was used for the footprint of the Facility to represent themix of acoustically hard and soft surfaces found there, which are primarily composed of gravel. Theareas surrounding the site, which are primarily grassy areas, were modelled with a ground absorptioncoefficient of 0.70 to represent the generally absorptive surfaces.

Sound QualityAll noise sources were determined to be steady in nature with no tonal characteristics. There are also noimpulsive noise sources at the Facility, as per the confirmation of the previously approved AAR (seeAppendix A).

4.6 Point of Recep on Noise Impact Table Table 4 summarizes the contribution of each noise source to the overall noise level (i.e., Partial Levels)at each of the representative receptors.

Graphic output from the model illustrating sound level contours and predicted receptor noise levels arepresented in Figure 4 and Figure 5 for the regular operations during daytime and evening/nighttimehours, respectively, and Figure 6 for the emergency equipment testing scenario. A CADNA/A modelsample output for is provided in Appendix D.

5.2 Ra onal for Selec on Applicable Noise Guideline Limits Acous c EnvironmentThe background ambient noise, exclusive of the Facility, can be characterized as being dominated bysounds of nature and consistent with a Class 3 area as described in NPC-300.

As per MECP noise publication NPC-300, the noise limit criteria at sensitive points of reception due tothe operation of stationary sources are the greater of the following:

1. Exclusionary minima values specified in the applicable MECP NPC-300 document; or2. The lowest background hourly sound level equivalent (Leq (1hr)) occurring at the sensitive point

of reception at the same time of day that the equipment is operating.

6.0 Conclusion 14


As a Class 3 Area, the noise sources under assessment would be considered compliant with NPC-300 ifthey are at or below either the exclusion limits (see Table 7 and Table 8 below) or the backgroundambient noise levels as measured or calculated. For the purposes of this assessment, the MECP’sapplicable exclusionary limits were used as the performance limits for daytime, evening, and nighttimeperiods.

Executive Summary

Enbridge Pipelines Inc. (Enbridge) filed an application (the Application) on January 28, 2015 to amend their Basic Comprehensive Environmental Compliance Approval (ECA) for Enbridge’s Westover Terminal (the Facility). This application in included an Acoustic Assessment Report (AAR). Since filing, Enbridge has been planning work at the Facility for the Line 10 Westover Segment Replacement Project (the Project), which has the potential to change the results of the Acoustic Assessment Report (AAR). Novus Environmental Inc. was retained by Enbridge to prepare an updated AAR based on the Project changes.

The purpose of this AAR is to determine the noise and vibration impact from the operations of equipment at the Facility on the most sensitive points of reception in all critical directions surrounding the Facility. This update also includes the latest proposed changes resulting from the Project.

The Facility is located at 1430 6th Concession Road West RR2, in Branchton, Ontario. The Facility acts as a storage area and a transportation hub for the distribution of various crude oil products. The Facility and its equipment operate up to 24 hours per day, 7 days per week.

An AAR, dated October 28, 2013, was previously completed by RWDI AIR Inc. (RWDI), submitted, and approved by the Ontario Ministry of the Environment and Climate Change (MOECC) as a component of the current Amended ECA No. 8758-9BVKTU. Additional noise sources of concern include new emergency generators, and vacuum trucks associated with Pipeline Inspection Gauge (PIG) launch and receipt. The proposed relocation of the Line 10 PIG trap (part of the proposed Project scope) is also included in this assessment.

On-site sound level measurements were completed on October 30, 2014 by Novus personnel of the new emergency generators and mainline pumps. These measured sound levels, in addition to sound level data used in the RWDI AAR, were used as inputs to a predictive acoustical model to quantify outdoor noise emission associated with the Facility. Acoustic assessment criteria were established in accordance with sound level limits defined in MOECC publication NPC-300.

Road traffic data for the surrounding area is not expected to be significant. Therefore, default guideline limits were used in this assessment.

Four (4) locations have been identified as being representative of the most sensitive points of reception (PORs) surrounding the Facility. These receptor locations can be best defined as Class 3 rural, as per MOECC Publication NPC-300. The Facility is not a significant source of vibration.


Novus Environmental

The noise measurements and analysis indicated that current sound emissions of the Facility meet applicable sound level limits during the predictable worst case hour of operation. No additional mitigation measures or operational restrictions are necessary.

1.0 Introduction

Enbridge Pipelines Inc. (Enbridge) filed an application (the Application) on January 28, 2015 to amend their Basic Comprehensive Environmental Compliance Approval (ECA) for Enbridge’s Westover Terminal (the Facility) that included an Acoustic Assessment Report (AAR). Since filing the Application, Enbridge has been planning work at the Facility for the Line 10 Westover Segment Replacement Project (the Project), which has the potential to change the results of the Acoustic Assessment Report (AAR). Novus Environmental Inc. (Novus) was retained by Enbridge to prepare an updated AAR based on the Project changes.

The Facility is located at 1430 6th Concession Road West, in Branchton - Town of Flamborough - Hamilton, Ontario. The Facility acts as a storage area and transportation hub for the distribution of various crude oil products. The Facility and its equipment operate up to 24 hours per day, 7 days per week.

An AAR, dated October 28, 2013, was previously completed RWDI AIR Inc. (RWDI), submitted, and approved by the Ontario Ministry of the Environment and Climate Change (MOECC) as a component of the current Amended ECA No. 8758-9BVKTU. A copy of the current ECA is included in Appendix A. Additional noise sources of interest include new emergency generators, and vacuum trucks associated with Pipeline Inspection Gauge (PIG) launch and receipt. The proposed relocation of the Line 10 PIG trap (part of the proposed Project scope) is also included in this assessment.

This report has been prepared in accordance with the applicable MOECC publications (i.e., NPC-103, NPC-233, NPC-300). The purpose of the assessment is to evaluate the overall noise emissions of the Facility with respect to MOECC noise guidelines. The Facility is not a significant source of vibration and therefore there was no need for a vibration assessment.

A scaled area location plan showing the site with respect to the surrounding area and modelled noise sensitive receptors is provided in Figure 1. A site layout plan, showing the Facility arrangement and source locations, is provided in Figure 2. A land use zoning designation plan is provided in Appendix B.

Noise sensitive points of reception were selected that are representative of all sensitive points of reception in all directions around the Facility. For the purpose of this assessment, four (4) locations have been selected to represent the sensitive Point(s) of Reception (POR(s)), labelled as POR1 to POR4 in Figure 1. The closest POR is located approximately 300 m from the closest Facility noise source (see Figure 1).



2.0 Facility Description

Within the Facility there are eight (8) crude oil storage tanks. The Facility stores and transports crude oil products and the existing eight (8) storage tanks are connected to lines which transport product on-site for storage as well as off-site for delivery. Six (6) of the tanks are external floating roof construction and two (2) of the tanks are domed external floating roof construction. No product processing is conducted on site.

This application includes the existing noise sources previously reviewed and approved by the MOECC, in addition to the three (3) new diesel fired emergency generators, and the operation of vacuum trucks during PIG launch and receipt.

The ground elevation contours for the Facility are generally flat in nature, with elevated ground contours to the north-west. In addition, the row of storage tanks along the north edge of the site and the firewater pumphouse building are elevated in comparison to the remainder of the site. The elevation differences can range up to 8 m height change.

It is Novus’ understanding that there have been no complaints regarding noise due to the operation of the Facility.

3.0 Noise Source Summary

The primary noise sources of concern are summarized in Table 1, in the Tables section, and include the following:

Three (3) outdoor emergency generators;

One (1) fire water pump, located within it’s own building

Two (2) portable generators;

Four (4) potential vacuum truck locations (only one (1) operational at a time);

Three (3) outdoor Line 10 mainline pumps;

Two (2) outdoor Line 11 mainline pumps; and

One (1) Welding Exhaust.

The locations of the significant noise sources can be found in Figure 2.

A summary of insignificant noise sources is included in Appendix C.

Five portable generators, only 2 in use at a time



4.0 Points of Reception

A total of four (4) PORs have been identified as being representative of the most sensitive PORs in the vicinity of the Facility, labelled POR1 to POR4 in Figure 1. As per MOECC noise guidelines, “Point of reception” means any location on a noise sensitive land where noise from a stationary source is received. For the purpose of an AAR the points with “the predictable worst case noise impacts” must be considered. The PORs are summarized below.

POR1: Was assessed as a two (2) storey house to be conservative (replaces NR1 in the RWDI AAR). This POR is located north-west of the Facility, along the south side 6th Concession Road West. POR1 is considered to be the worst-case receptor to the west due to the elevated ground elevations. In addition, the other houses along 6th Concession Road, between POR1 and POR2, are either bungalow or split-level homes. Hence POR1 was found to have the worst-case noise impacts. POR1 is located approximately 480 m from the nearest Facility noise source. As a conservative assessment of impacts, the upper floor window (h = 4.5 m) was used as the worst-case receptor location. Actual source-to-receptor separation distances are provided in Table 2.

POR2: Is a two (2) storey house (additional receptor). This POR is located to the north of the Facility, on the north side of 6th Concession Road West. POR2 is considered to be the worst-case receptor to the north due to a drop in the ground elevation contours between the north row of tanks and existing ground contours to the north-west. POR2 is located approximately 350 m from the nearest Facility noise source. The second storey window (h = 4.5 m) was used as the worst-case receptor location. Actual source-to-receptor separation distances are provided in Table 2.

POR3: Is a two (2) storey house (formerly NR2 in RWDI AAR). This POR is located north-east of the Facility, along the south side 6th Concession Road West. POR3 is located approximately 300 m from the nearest Facility noise source, and is separated by a thick forested area. As a conservative assessment of impacts, the effect of the forested area has not been included in the assessment and the upper floor window (h = 4.5 m) was used as the worst-case receptor location. Actual source-to-receptor separation distances are provided in Table 2.

POR4: Is a one (1) storey house (formerly NR3 in RWDI AAR). This POR is located east of the Facility, along the west side Westover Road. POR4 is located approximately 600 m from the nearest Facility noise source, and is separated by a thick forested area. As a conservative assessment of impacts, the effect of the forested area has not been included in the assessment. A receptor located along the west boundary of the backyard at a height of 1.5 m was used as the worst-case receptor location. Actual source-to-receptor separation distances are provided in Table 2.



There are no PORs within 500 m to the south of the Facility.

5.0 Assessment Summary

5.1 Performance Limits

The Facility is located in Branchton, Ontario. The subject area is defined as Class 3, as per MOECC Publication NPC-300 (MOECC 2013). This publication describes a Class 3 Area as “a rural area with an acoustical environment that is dominated by natural sounds having little or no road traffic.” This is consistent with the observations made by Novus personnel for the surrounding area.

The Exclusion Limit Values for One-Hour Equivalent Sound Level (Leq, dBA) for Outdoor Points of Reception in a Class 3 area are summarized below.

Daytime (7 am to 7 pm): 45 dBA Evening (7 pm to 11 pm): 40 dBA

The Exclusion Limit Values for One-Hour Equivalent Sound Level (Leq, dBA) for Plane of Window of Noise Sensitive Spaces in a Class 3 area are summarized below.

Daytime (7 am to 7 pm): 45 dBA Evening (7 pm to 11 pm): 40 dBA Night-time (11 pm to 7 am): 40 dBA

The sound level limits applied for the assessment are the higher of the applicable MOECC NPC-300 Exclusion Limit Values or the background sound levels, primarily from roadway noise. Since road traffic noise is not significant during all periods of the day, the background noise levels are not expected to exceed the Exclusion Limit Values. Hence the Exclusion Limit Value limits have been used in this assessment. Table 3, in the Tables section, summarizes the applicable sound level limits for each receptor location.

Sound level limits do not apply to emergency equipment operating during emergency situations. However, emergency equipment operating in non-emergency situations, such as testing or maintenance of such equipment, requires assessment under NPC-300. The sound level limits for emergency equipment operating in non-emergency situations are 5 dB greater than the sound level limits otherwise applicable to stationary sources, as described above. Additionally, emergency equipment operating in non-emergency situations is to be assessed independently of all other stationary sources of noise.

Outdoor points of reception (modelled at 1.5 m above grade) will typically benefit from greater ground absorption and screening effects. Therefore, the upper floor plane-of-window noise



sensitive areas are considered to be the worst-case receptor locations due to the reduced ground absorption and screening. In this assessment, the outdoor points of reception were conservatively represented by upper floor plane-of-window impacts for POR1, POR2 and POR3, where noise levels for at-grade outdoor points of reception will be less than those presented in Table 3. Since POR4 is a single storey building, the worst-case location for assessing noise impacts was considered to be the west limit of the rear yard.

5.2 Impact Assessment

5.2.1 Operating Scenarios

As a conservative approximation of impacts from typical operations, all sources were assumed to be in continuous operation, simultaneously. The exceptions are the vacuum trucks used during PIG launch/receipt, in which only one (1) of the four (4) possible locations would be used at a given time. In addition, the Generator Testing was predicted independently of the Facility stationary sources, per the NPC-300 criteria.

Therefore, the following scenarios were assessed:

Scenario 1, Typical operations – All sources in operation simultaneously, excluding generator testing. The worst-case location for vacuum truck operation (location PT07) was included in this scenario. The individual impacts for each vacuum truck location are included in Table 2.

Scenario 2, Generator Testing – All generators tested simultaneously, excluding other Facility noise sources. Generator testing was assessed based on a conservative, 1-hour duration, which is excessively conservative since the units are tested individually for 10 to 20 min periods only. The generator testing impacts are shown against the daytime, evening and night-time limits as a conservative representation of impacts, even though generator testing is typically completed during daytime hours only.

Sound level measurements were completed during a visit in October 2014 for the 200 kW generator, the Line 10 mainline pump (source Pump10_1) and the grouping of the Line 11 mainline pumps (source Pump11_group). Information pertaining to the measurement equipment and weather conditions are provided in Appendix D.

All other sound levels used in the assessment were taken from the MOECC reviewed RWDI AAR, with the exception of the PIG launch/receipt vacuum truck. Historical sound level measurements of a vacuum truck in operation at the Enbridge Sarnia Terminal were used in this assessment. The vacuum truck was observed to be in operation at low speed for the duration of the PIG launch. Operation of the Vacuum Truck at close proximity (approximately 10 m) was found to not possess any tonal or buzzing characteristics. Therefore, no penalties were applied for this source.



Based on observations made by Novus personnel, the typical facility operations were found to be not tonal at the noise sensitive receptors. Therefore, no penalties were applied to any sources.

The noise source sound power levels are summarized in Table 1, in the Tables section of this report. Sound level data used in this assessment are included in Appendix E.

5.2.2 Noise Impact Modelling

Sound level data were used as input for sound level prediction calculations at the identified receptors. The calculations were performed using Cadna/A, a prediction software consistent with the ISO 9613-2 standard (ISO 1996). The model took into consideration the layout of the Facility, the location of the sources, ground elevation contours surrounding the Facility, and relative changes in the site ground elevation contours. As described in ISO 9613-2, ground factor values that represent the effect of ground absorption on sound levels range between 0 and 1. Based on the specific site conditions, the ground factor values used for modelling the Facility was 0.5 for a mixture of acoustically hard and soft surfaces, which is primarily composed of gravel. The surrounding area was modelled as a ground factor of 1, based on the acoustically soft surfaces (e.g. grass).

The predicted sound levels at the identified PORs, due to each noise source, are summarized in Table 2 in the Tables section. The table also includes the distance from each source to the identified PORs. Sample calculations are provided in Appendix F for POR1.

Predicted sound level contours at an elevation of 4.5 m are shown in Figure 3 and Figure 4 for Scenario 1 – Typical Operations and Scenario 2 – Generator Testing, respectively. Figure 5 and Figure 6 show the corresponding sound level contours at an elevation of 1.5 m for Scenario 1 and Scenario 2, respectively. The cumulative noise impacts at the identified PORs are summarized in Table 3 for the worst-case 4.5 m second storey window in the Tables section. The predicted noise impacts are shown to be at or below the applicable guideline limits for both scenarios.

6.0 Conclusion

Novus was retained by Enbridge to prepare an Acoustic Assessment Report for their Westover Terminal located at 1430 6th Concession Road West RR2, in Branchton, Ontario. All Facility noise sources have the potential to operate during any hour of the day, with the exception of generator testing. Based on the above assessment, the applicable sound level limits (performance limits) are predicted to be met in all noise sensitive areas, during all periods of the day. No additional mitigation or operational restrictions are required.
