3. MINUTES FROM PREVIOUS MEETING
The Committee agreed the Minutes of Meeting 12 held on 22 November 2018 were a true and correct record.
A question was raised regarding agenda item 7 ‐Water Regulatory Reform Directions Paper feedback. Chair advised that members could make comment individually on the departments’ website. The Committee did not meet before the 31 March deadline for comment; however, an extension has been granted. This can be discussed at agenda item 7 of this meeting.
4. UPDATE ON THE OOLLOO PLAN (PLANNER)
Members were provided with an Oolloo Water Allocation Plan Status update and a presentation on advice received by the Australian Government Solicitor (Appendix 1).
The department requested the Australian Government Solicitor to give particular attention to:
the interpretation of the estimated sustainable yield (OOS paper 13.1) allocating water to beneficial uses (OOS paper 13.2) any areas where the plan could be considered to fetter the Controller the consideration of surface and groundwater extraction from within the same
consumptive pool general compliance with legislative requirements comments
The Australian Government Solicitor advised that the draft Oolloo Water Allocation Plan does not appear to limit the Controller in how they should act. It saw no barrier in the legislation to surface and ground water extraction licences coming from the same pool. Subject to the considerations being raised today being addressed, the Plan was considered to generally comply with regulatory requirements under the Water Act 1992.
Members were provided with a summary diagram of the modelled water balance for the Oolloo Dolostone Aquifer from 1967 – 2018. The model provides the basis for making decisions about the water allocations in the plan. It shows that long‐term
4
aquifer recharge equals long‐term aquifer discharge plus any changes to aquifer storage.
Updates to cultural values since the last meeting were discussed. The main changes were as a result of consultation with Traditional Owners. This has led to some changes to better describe the water requirements of cultural values and recommendations for a reference group and planning to protect cultural values.
Members suggested that for future planning processes, Committee Members should be provided with finalised draft Water Allocation Plans before it goes to public consultation.
5. DISCUSSION ON THE MAIN PLAN ELEMENTS (All)
5.1 Estimated sustainable yield (OOS 13‐1)
Adrian Tomlinson thanked Members for feedback and gave a presentation to the Committee (Appendix 2).
The information contained in OOS 13‐1 follows advice from the AGS around the definition of estimated sustainable yield (ESY).
Section 22B (6) of the Water Act 1992 states the ESY has to include an allocation for the environment. The Australian Government Solicitor emphasised that to meet the requirements under the Act an allocation to the environment from the ESY is needed. However it noted that allocating water to the beneficial use of environment is not strong protection as compared to provisioning water for the environment prior to defining the ESY.
5
Consumptive pool = sustainable extraction Non‐consumptive pool = environmental and cultural requirements.
Based on the advice received a nominal allocation to the environment of 20 ML per year, per Management Zone has been recommended. It was noted an allocation to the environment 0 ML did not constitute an allocation.
It was discussed that future Water Allocation Plans should make clearer the allocation to the environment before determining the ESY.
Discussion was held around cultural flows. There is no information on what the flows needed to meet cultural values are. At this stage environmental flows are considered the best proxy for cultural flows. There is a need to improve knowledge of cultural flows. Information should be available for the review of the Oolloo Water Allocation Plan.
The 80:20 rule was explained. This plan uses this principle except on dry flow periods when additional water is provisioned for environmental and cultural flows based on Erskine. For example at Dorisvale Crossing when river flows are below 6.2 m3/s only 8% of groundwater discharge can be taken. Over 6.2 m3/s 20% of groundwater discharge can be taken.
ACTION – Wording in draft Oolloo Water Allocation Plan explaining 80:20 rule and local Erskine criteria is to be made clearer.
Members were provided with a presentation on updated flows based on two more years’ data and calculated on median rather than average.
6
Advice from BoM is to use median over means. In the case of discharge from the Oolloo Dolostone Aquifer the difference between the amount available for extraction under a median versus a mean is very small (about 1 GL/year).
There is a need to use the longest time period to give the most information on flows and recharge rates.
Members raised concerns regarding changing data calculations. There is a need to better record why and how these decisions are made at this point in time. This should be included in the NT Allocation Framework as part of the principles and criteria that determine how the ESY is calculated.
The WAC accepted the new definition of estimated sustainable yield, noting allocation to the environment and terminology ‘extractable’ not ‘divertible’.
The WAC accepted the new estimated sustainable yield values in Tables 1, 11, 13 and 14 of the Water Allocation Plan, noting environmental allocation.
5.2 Allocation to consumptive uses (OOS Paper 13‐2)
Members were provided with an update on allocation of consumptive uses and a presentation (Appendix 3).
Advice from the Australian Government Solicitor is to make an allocation to each beneficial use and not a general pool. The department is proposing to make nominal allocations to each consumptive beneficial use as per table below.
Mining and petroleum activities are subject to the Water Act 1992 and classed as a beneficial use.
7
Currently there is no petroleum activity in the water planning area and potentially minimal mining activity. There could be a small volume of water needed to account for existing mining use that will eventually get a water extraction license.
A question was raised as to what happens if the mining activity water use is more than the 20 ML allocated. As it is an existing use, these entitlements would need to be accounted for. This theoretically could cause the total amount of entitlements to be greater than the ESY. However, water cannot be taken back retrospectively as the authority to take water at the time came from the Mining Act. In the future, a new mining activity would have to make an application for water and that is a decision for the Controller.
A question was also raised regarding the difference between cultural consumptive and non‐consumptive beneficial uses. Cultural water use can be both and can fall into two categories: non consumptive cultural water reserved before setting the ESY, and cultural water set under a licence which is water for recreational and aesthetic type uses. Allocation to the Strategic Aboriginal Water Reserve is for the Aboriginal people for economic benefit and is not a cultural water allocation.
Cultural water use as defined in legislation is not only for Aboriginal cultural use and protection of Aboriginal cultural values. Its definition should therefore be clarified in the draft Plan. The plan should make clear when Aboriginal cultural values are being described as opposed to cultural water use as defined by legislation. It was noted that there is limited scope to changing definition as it is defined in the Act.
ACTION – Update draft Oolloo Water Allocation Plan to be more descriptive of ‘cultural’ terminology.
8
The WAC agreed on the nominal allocations of 20 ML to some declared beneficial uses.
The WAC agreed with the proposed allocations to each declared beneficial use in Table 1.
5.3 Update on the current water account
Members were provided with an update on the current water account and a presentation (Appendix 4).
The updated table shows the outcome in terms of the current level of entitlements and use after adopting the revised ESY.
Members advised that the table would make more sense if the full Strategic Aboriginal Water Reserve allocation and not just the available allocation was noted. It was discussed that as the SWR allocation cannot be met, while entitlements are within the ESY, entitlements for general use exceed their allocation and so the system should be considered over‐allocated.
It was agreed that the plan should show the full Strategic Aboriginal Water Reserve and therefore how much of that Strategic Aboriginal Water Reserve is notional and how much is available for allocation.
It was noted that the Strategic Aboriginal Water Reserve section in the draft Plan explains how much is in the Reserve, how much is currently available (only in the Southern and Central zone) and options available for how the Strategic Aboriginal Water Reserve may be activated.
The WAC notes updated information on the water account in Table 1 for use in the draft Oolloo Water Allocation Plan, noting other items are in play.
9
ACTION – Update Executive Summary of the draft Oolloo Water Allocation Plan to make this clearer.
ACTION – include a line in the Table stating notional Strategic Aboriginal Water Reserve figures
5.4 Principles for granting new entitlements
Members were provided with a recommended position for when a new licence could be considered and a presentation (Appendix 5).
Clarification is being sought on principles to be put in place when applying for a licence. In the November meeting the Committee made a recommendation that if any zones are over allocated then no new allocations should be approved. The department is seeking to modify this position as it limits the issuing licences in other management zones where water is available.
Members advised that there is a need to be very conscious of the impact of one zone on another zone. Members noted that all zones are notionally over allocated (if the SWR amounts were included), so it was effectively in principle agreement being sought.
Members were asked to support a modified statement that if all the above criteria is met and there is enough water flowing over Dorisvale, Oolloo Crossing and Mt Nancar, then the plan should recommend that licences can be issued.
This required the Committee to retract the statement that if any zone is over allocated, no zone allocations should be approved and replace with this new recommendation.
10
The WAC agreed with the principles in this process to be used to decide whether an entitlement can be issued.
5.5 Seasonal Outlook for the Oolloo area
Members were provided with a presentation on the seasonal outlook for the rest of 2019 on river flows and aquifers in the Oolloo plan area (Appendix 6).
The presentation focused on:
Data on how ground water levels have responded this year Flow of the Daly River Modelling to quantify how much recharge was received in the Oolloo
Dolostone Aquifer Flows as at end of the dry season.
Current ground water levels based on four bores in the Oolloo Dolostone Aquifer remain higher than historical dry periods but have not seen much recharge in 2018‐19. Projected natural and impacted flows under current level of use were provided for Mt Nancar and Dorisvale. These suggest that reasonable dry season flows will be maintained this year.
Clarification was sought on the accuracy of the flow model based on this years’ poor Wet season and the fact the Daly River is getting shallower. The department is confident the flow model will stand up.
It was noted that the figures in this presentation are from 1967–2015 and are averaged based. Details used in the draft Oolloo Water Allocation Plan are for a different time period (1967–2018) and median based.
Members requested information on:
What happens if there is no recharge next year? How many years would it take to use up the ‘banked’ water?
How does current use compare with full use for this year and future years?
ACTION – Des Yinfoo to provide water model based on this information to Tim Bond to present to Committee members.
6. PUBLIC CONSULTATION PROCESS FOR THE DRAFT WAP (Planner)
11
Members were provided with a draft Communications and Engagement Plan based on discussions from meeting 12 and a timeline for public consultation (Appendix 7). The Communications and Engagement Plan formalises the consultation process and provides an evaluation.
The aim is to have to the draft Oolloo Water Allocation Plan to the Minister by 14 May and out for public consultation on the 24 May. The consultation process will run for six weeks with submissions available for consideration by the Committee two weeks prior to the next meeting.
Members noted that this timeline may change based on the Minister’s availability.
Presentations have commenced with stakeholders and Traditional Owners with more presentations planned. Members are asked to notify the department if stakeholders within their area wish to have a presentation to discuss the Plan. Members will also be invited to attend the presentations organised by the department in their areas.
A comment was made that wording in the draft Communication and Engagement Plan is confusing and needs to be changed to: Oolloo Dolostone Aquifer in the Daly Roper Beetaloo Control District.
It was noted that Members will not see the draft Oolloo Water Allocation Plan before it goes for consultation. In terms of cohesion and cross referencing, they are depending on the department to err on the side of exercising caution in managing risks. It was noted the updated Plan will be more explicit with the allocations to beneficial uses and amounts of water available.
Key messages updates:
454ML/yr is being provided for environment and cultural outside of the ESY
Add to dot point 8 under part 2 of Key messages – …water has not yet been allocated to Strategic Aboriginal Water Reserve. All of the 9,830 ML available of it is allocated to the Strategic Aboriginal Water Reserve. The key messages regarding water availability should make clear no new water is available except through the Strategic Aboriginal Water Reserve or trade process. This should be upfront in the key messages.
ACTION – Members to advise if any stakeholders in their areas wish to have a presentation to discuss the draft Oolloo Water Allocation Plan. Alternatively, members are to be invited to presentations organised by the department when in their area.
ACTION – Update title to state Oolloo Dolostone Aquifer in the Daly Roper Beetaloo Control District.
12
ACTION – Provide version of the draft Oolloo Water Allocation Plan sent to the Minister as well as the final Communication and Engagement Plan to the Committee.
ACTION – Update key messages and ensure the Plan is more explicit with numbers and availability at this stage only via the SWR.
ACTION – Consider updating the front cover picture of the Oolloo Water Allocation Plan.
7. COMMITTEE’S RESPONSE TO THE WATER REGULATORY REFORM DIRECTIONS PAPER
(Chair)
Members were provided with a copy of the Northern Territory Water Regulatory Reform Directions Paper. Some Members have already made individual submissions to the Reform Paper. Chair advised Members if anyone wishes to provide further submissions, to get in touch with him.
Questions were raised on where stock and domestic sits in the diagram on page 3 (how water is allocated) and the sustainable water usage on page 5 of the Reform Paper. Tim Bond advised that stock and domestic sits within the consumptive pool process. A suggestion was received that this should sit on its own. Tim Bond also provided an explanation on trading within aquifers and between zones.
No further comments from the Committee as a whole.
8. KEY MESSAGES FROM THIS MEETING (Chair)
Reiterated the need to include the definition of ‘cultural’ terminology in the glossary/index. No other items discussed.
9. NEXT MEETING (Chair)
Next meeting scheduled for 30 July 2019, where the Committee will consider responses to submissions received.

ESY Definition Instincts / common sense The ESY is the amount of water that can be sustainably taken after the water requirements of environmental and cultural values are met
Legislation Under Section 22(B) of the Water Act 1992 the ESY must include an allocation to the environment. Not doing this was arguably not in accordance with the Act.

3. There must be enough water flowing over Dorisvale, Oolloo Crossing and Mt Nancar
1. The ODA overall is not under allocated 2. Water available in EVERY
the management zone
Order 1. Non consumptive and
priority beneficial uses 2. SWR 3. General pool
Paper 4 ‐ principles for new entitlements • The Committee is requested to reconsider the statement from the
November 2018 meeting: “if any zones are over-allocated then no new allocations should be approved”.
• This could unreasonably limit opportunities to sustainably access water
• There is unallocated water for consumptive use in the Southern and Central zones
• Water could be taken in the Southern and Central zones without compromising the environmental flows in any management zones
