Te Anau Wastewater Discharge Project Committee - Terms of Reference

Record No:        R/17/3/6353

Author:                 Steve Ruru, Chief Executive

Approved by:       Steve Ruru, Chief Executive

 

  Decision                              Recommendation                         Information

 

  

 

Purpose

1        To brief the Committee on its revised Terms of Reference, which have been approved by Council at its 15 March 2017 meeting.

Executive Summary

2        The Council has executed a Deed of Agreement with Fiordland Sewerage Options which requires Council to assess the viability of the Smith Block, as an alternative to the Kepler Block, for wastewater disposal.

3        The decision to enter into the Deed of Agreement changed the scope of the project which was previously being pursued. In light of these changes Council asked officers to report back with suggested changes to the terms of reference for the Te Anau Wastewater Project Discharge Committee. This report was presented to Council at its 15 March 2017 meeting.

4        Attached for the information of the Committee are the revised terms of reference which were approved by Council. The changes reflect the change in scope and the work that now needs to be completed prior to Council proceeding into the construction phase of the project.  It is appropriate that the Committee consider how it wishes to work and whether it has any specific information requirements to enable it to meet the terms of reference that have now been approved by Council.

 

Recommendation

That the Te Anau Wastewater Discharge Project Committee:

a)         Receives the report titled “Te Anau Wastewater Discharge Project Committee - Terms of Reference” dated 29 March 2017.

b)         Determines that this matter or decision be recognised as not significant in terms of Section 76 of the Local Government Act 2002.

c)         Determines that it has complied with the decision-making provisions of the Local Government Act 2002 to the extent necessary in relation to this decision; and in accordance with Section 79 of the Act determines that it does not require further information, further assessment of options or further analysis of costs and benefits or advantages and disadvantages prior to making a decision on this matter.

d)         Consider how it wishes to operate to ensure that it fulfils the terms of reference that have been set by Council and provides direction to staff on any specific requirements it has to enable it to perform its functions more effectively.

 

Content

Background

5        At its meeting on 21 December 2016 the Council approved a Deed of Agreement with Fiordland Sewerage Options (FSO), which provided for:

·    Council agreeing to proceed with investigation of the Smith Block to determine whether it is a viable alternative when compared to the consented Kepler scheme.

·    Council being able to determine at any stage during the investigations not to proceed further with the investigation if it concludes that the Smith block is not a viable alternative to the Kepler.

·    Council deciding at the end of the investigation and consenting programme whether to proceed with either the Kepler or Smith options. 

·    FSOI agreeing to withdraw their appeals against the Kepler consents with costs lying where they fall. 

6        The decision to approve the Deed of Agreement meant that the scope of the work to be progressed changed from being a peer review exercise to consideration of one particular alternate disposal site. As a result Council asked officers to report back with revised Terms of Reference for the Te Anau Wastewater Discharge Project Committee.

7        Previously, the Committee had, for example, been charged with completing the peer review process and making recommendations to Council as to how it should proceed with the project given the findings of that review. The Deed of Agreement provides that Council must evaluate, in accordance with the steps outlined in the appendix, the Smith Block to determine whether it is a viable option relative to the Kepler Block. The Council can then make a decision about which option it wishes to pursue.

Issues

8        The Committee needs to be aware of the changes which Council has made to its terms of reference and consider how it wishes to work ensure that it meets the role that it has been asked by Council to perform. The Committee could also provide direction to staff as to any specific requirements for information or advice that it may have to enable it to perform its functions more effectively.

 

Factors to Consider

Legal and Statutory Requirements

9        Under the Local Government Act 2002 a local authority is able to establish the committees, sub-committees and other sub-ordinate decision making bodies that it considers appropriate.

10      All such committees are subject to the ultimate control of and must comply with any general or specific directions given by the Council. They also represent Council and are able to make decisions that are binding on Council.

Community Views

11      In forming the Project Committee in 2015 the Council was conscious of the need to ensure that there was a conduit via which the views of the local communities could be identified and considered as part of Council’s decision making process. This position is not changed by the changes to the terms of reference outlined in this paper.

Costs and Funding

12      Costs of the Project Committees operations are met from the Governance budgets.

Policy Implications

13      The Project Committee is required to operate within the Council governance policies including its code of conduct and standing orders.

Analysis

Options Considered

14      The options considered are for the Committee are to Do Nothing or Consider Implications of the new Terms of Reference for the way in which it wishes to work.

15      Under the Do Nothing option the Committee would simply receive the report. Staff would then provide the advice and other progress reports that they consider are needed to enable the Committee to perform its role.

16      Under the Consider Implications option the Committee would specifically consider and provide direction to staff on any information requirements/expectations it may have to be able to meet its obligations to the Council.


 

Analysis of Options

Option 1 – Do Nothing

Advantages

Disadvantages

·        Committee will be required to operate within terms of reference set by Council. 

·        Staff will not have clear guidance as to the expectations that Committee members have.

·        Committee may not receive all of the advice that they need to perform its functions effectively.

 

Option 2 – Consider Implications

Advantages

Disadvantages

·        Enable the Committee to fulfil the role that it has been asked by Council to perform more effectively.

·        Enable staff to more effectively provide the advice that the Committee needs to perform its role.

·        None identified.

 

Assessment of Significance

17      The issue being considered relates to the Committee noting the revised terms of reference which have now been approved by Council that it is required to operate within. As such a decision in accordance with the recommendations is not considered significant. 

Recommended Option

18      The recommended option is for the Committee to consider the implications of the new Terms of Reference on the way in which it wishes to work.

Next Steps

19      Staff will ensure that the information required by the Committee is provided at future meetings.

Updated Management Report to the Te Anau Wastewater Discharge Project Committee

Record No:        R/17/4/7600

Author:                 Ian Evans, Strategic Manager Water and Waste

Approved by:       Steve Ruru, Chief Executive

 

  Decision                              Recommendation                         Information

 

  

 

Purpose

1        The purpose of this report is to keep Committee members updated on the progress of works being undertaken within the Te Anau and Manapouri areas that are not necessarily related to the larger discharge consent project. 

2       The report will be updated and presented at all upcoming Committee meetings.  This information is up to date as of the week commencing 3 April 2017.

Status Report on Ongoing Work

3       Discharge Consent Application

·                      Consent was granted 15 January 2015.

·                      Three appeals were subsequently lodged with the Environment Court (EC).

·                      Both Council and appellants agreed to participate in court appointed mediation.

·                      Response to EC was lodged by Environment Southland (ES) on 29 May 2015 indicating the position of all parties to the appeal.

·                      Further hold until 18 December, with the expectation this will be extended pending the outcome of the peer review.

·                      Council’s legal advisors reviewed the Pattle Delamore Partners (PDP) report and provided legal advice on implications of the peer review outcomes.  They also prepared a response to the EC.

·                      Court appointed mediation occurred on 20 and 21 June 2016.  An update of the outcome of the mediation process is included in an additional report on the agenda for 6 July meeting.

·                      Appeal settled December 2016 with execution of Deed of Agreement.

4       Designation 80 Process

·                      Council approved Commissioners’ recommendation to grant designation on 8 April 2015.

·                      One appeal was received but rejected by the EC.

·                      Council planning maps will be updated to show the designation.

·                      No further work required around this item at present.

5       Short Term Discharge Consent Application

·                      Application lodged with ES on March 2014.

·                      Additional information provided as requested.

·                      Affected parties identified and written approvals provided to ES.

·                      Draft conditions have been accepted by Council.

·                      Draft conditions have been discussed with ES on 17 August.

·                      Further information in support of the application has been supplied to
ES.  Draft conditions have been agreed and awaiting further feedback.

·                      Short term consent was granted November 2015.

·                      No appeals received within statutory period hence this item deemed complete.

6       35 Year Discharge to Air Consent Application (for oxidation ponds)

·                      ES requested that discharge to air element of oxidation pond be separated.

·                      Consent for 35 years was applied for.

·                      An Odour Management Plan has been drafted and will be submitted as part of the application.

·                      Meeting with ES has been scheduled for 17 August 2015 to agree processing times, draft conditions etc.

·                      The consent is likely to be processed on a non-notified basis subject to affected party approvals being sought.

·                      Unable to secure all identified written approval so the consent was processed on a limited notified basis to the one party who would not provide written approval.
One submission was received opposing the application as it stands citing issues relating to duration and operational issues around when the screens were installed and desludging was undertaken.

·                      A pre-hearing meeting was held on 23 March 2016 and while agreement was not reached, staff will undertake further work to help overcome concerns held by the submitter.  If agreement cannot be reached the application is likely to proceed to a hearing.

·                      A further meeting was held with Mr Slee on 24 May 2016 where he provided written approval to the consent application.

·                      Twenty-five year consent was granted on 2 June 2016.

7       Pond Desludging

·                      This work was required irrespective of the outcome of either appeal process.

·                      Hydra-Care established on the site and completed the initial sludge survey and sampling of the three ponds.

·                      They constructed the dewatering bund. 

·                      The bund has been constructed and fully lined.

·                      The desludging itself was carried out mid/late August which is slightly delayed from the previous report.

·                      Further delays to the desludging of the Winton pond delayed the start date in Te Anau until early September.

·                      Hydra-Care have completed work on the large pond and disestablished from site.  They will return in the new year to complete the remaining two smaller ponds.
Council staff currently in discussion with Hydra-Care around potential reinstallation.

·                      Hydra-Care re-established to site on 19 May 2016 to complete desludging of ponds two and three.  Work is now substantially complete.

8       Inlet Screen Upgrade

·                      Work required irrespective of the outcome of either appeal process.

·                      Te Anau Earthworks is undertaking the installation of the inlet screen.

·                      Earthworks commenced week commencing 18 May 2015. 

·                      Installation is now fully complete with electrical and telemetry connections and some pipework modifications now the only items of outstanding work.

·                      Final installation and commissioning have been undertaken and screen is now fully operational.

·                      No further action required to date and project is complete.

9       Caswell Road Stormwater Upgrade

·                      This project is in no way connected to the sewerage works, it is purely a stormwater upgrade.

·                      Works are all but complete except for the installation of the final sump and reinstatement of the works.

·                      The excess gravel that is not required by Fiordland College will be stockpiled at the ponds for use in future works. 

·                      It is expected that all works will be complete and the Contractor disestablished within a fortnight (weather dependent).

·                      If ground conditions are unsuitable, final grass sowing could take place in the spring.

·                      No further progress on this at present.

10     Upukerora Flood Defence Work

·                      ES is proposing flood defence work both upstream and downstream of the Upukerora Bridge.

·                      ES claims that work is necessary to protect both the bridge and Council’s oxidation ponds should the river deviate from its current course.

·                      ES indicates that any significant deviation could cause oxidation ponds to be inundated in the event of a significant flood.

·                      Any flood event will also increase the risk of the Upukerora Road downstream of the ponds being washed out.

·                      Risk of inundation also arises from not managing gravel levels in the river bed.

·                      Currently there is little demand for gravel and as a consequence, levels have increased over those previously measured.

·                      Meeting on 26 May 2015 discussed proposed works.

·                      As an outcome of the meeting, ES will investigate feasibility and costs of a proposed alternative. 

·                      The alternative proposal has been assessed and a draft with costs provided to Council on 24 July 2015. 

·                      Meeting with senior Council and ES staff agreed to delay the decision until the outcome of the peer review is known and understood as this may have implications for the degree of protection work required.

·                      Stakeholder meeting held at ES in December 2016 where expert parties for ES and the River Committee agreed to review proposed options and confirm viability.

11     Contact Tanks at Te Anau and Manapouri Water Treatment Plants

·                      Full assessment of the condition and serviceability of the contact tanks at both
Te Anau and Manapouri water treatment plants will be undertaken in the upcoming financial year.

·                      Design work to be undertaken in 2017/18 financial year.

12     Finance and Risk

·                      Financial estimates and risk registers have been developed and will be presented to the Committee at future meetings once they have been aligned to Council’s Risk Management Policy.

13     Recent Odour Issues

·                      Odour issues were initially identified on-site on Tuesday, 21 February 2017.  Council responded to this issue by its incumbent Water and Waste Contractor, Downer NZ, monitoring  This testing confirmed the pond’s overall primary oxidation pond performance was declining as average results were stable between the following counts as outlined below:

                     DO 1.0-2.0 g/m3 (around the inlet) with a pH of 7.4-7.6.

14     Although primary pond dissolved oxygen levels were lower than what was expected, effluent DO has consistently remained stable between 9.0-10.0 g/m3 during this period of time, as did pH and temperature, which is consistent with what you would expect.  This indicated that treatment was being provided by the system and there was no risk of untreated wastewater being discharged.

15     A sulphurous odour however was noted at site particularly around the primary oxidation pond, as was a change from a typical clarity of green to a misty brown appearance. 
Reports of odour were also received beyond the site boundary. 

16     It was also during this time that septic tank imports were halted.  Downer operators identified, during its routine inspection, a large fluorescent blue discolouration was present around the primary pond inlet at the times in which they were discharging which it is suspected is a contributory factor.  Odour was noticeable particularly to adjacent neighbours of the pond site when a wind direction was travelling in a direction of North East.

17     In response to the situation, Council and Downer staff undertook a number of remedial steps to help the pond recover, these being:

·                      Daily testing of dissolved oxygen across the pond as an indicator of pond health.

·                      Introduction of additional aeration, initially by hiring of pumps which were later supplemented with additional aerators brought in from outside the district.

·                      Stabilisation of pH in the pond by the bulk dosing of lime.

·                      Dosing of the influent with a nutrient rich food source (trade name Ensol 5000) to promote algal regrowth.

·                      Pumping across from ponds 2 and 3 into pond 1 to accelerate algal regrowth.

18     These measures were introduced in a step by step manner with the impact monitored prior to taking the next step.

19     By the end of the third week, since odour was first reported, monitoring results indicated that the ponds were improving with a marked improvement noted by the end of the following week.  This is typical with any biological system that it will require a period of time to recover.

20     As further precaution, Council staff also sought the advice from independent experts who agreed that the step by step approach was appropriate and that effectively staff had followed a logical consistent path that they believed appropriate.

21     Water and Waste staff have also liaised closely with ES staff including meeting out at
Te Anau on 3 March 2017.  ES have indicated that they are satisfied with Council’s response to the issue and acknowledged that a full recovery may take some time and that Council’s response should be consistent with that.

22     As of 30 March 2017 staff are reporting that the pond system is again performing to the level expected for this type of system.
