RELATED WASTEWATER CONSENTS (2009) - (2015)
What were the three main findings from the independant commisioners?
1 Impacts on tangata whenua values and interests
Tangata whenua have a long and well-known relationship with Turanganui a Kiwa (Poverty Bay) and its waters, fisheries and special sites. The waters have been identified as a taonga to local Iwi and as such their relationship should be protected as a matter of importance.
A major driver for the new wastewater system was to provide for tangata whenua and the wider community’s values and interests in the coastal environment of the Bay.
The 2009 decision of the Independent Commissioners made clear:
“The effects on tangata whenua from the existing wastewater arrangements at Gisborne and of the upgrade proposals has been a paramount consideration.
It has been made very clear at all times, and over many years now, that the continued discharge of untreated wastewater to the waters of Poverty Bay violates Maori tikanga and is a major effect on the cultural and spiritual sensitivities of tangata whenua.
A key component of the on-going action to implement an improved wastewater treatment scheme is the input from tangata whenua, in partnership with the other interested parties ....”
As stated in the 2014 report from WTAG:
“Restoring the mauri is a key theme for tangata whenua and many others in the community, and this is reflected in the consent and other regional planning documents. It is integral to the management of waste streams and water bodies in the District. The restoration of the mauri should be seen, however, as an iterative process. That is, in the context of the current consent, the process of developing and implementing a wastewater management system is itself critical to the concept: both the journey and the destination contribute to restoring the mauri, and so both must be valued and supported by the consent holder.”
The Council has taken steps to involve tangata whenua in the technical and management aspects of the proposals. This is evidenced by the establishment of the WMC and WTAG that both have broad iwi representation. It appears, based on the application and supporting information, that appropriate time and resources have been deployed to address concerns and identify solutions to meet cultural preferences. The proposal includes reference to programmes of work that will explore and address restoring the mauri of Turanganui a Kiwa at a catchment level, encompassing a holistic approach consistent with a Maori world view.
We note there do not appear to be any relevant iwi planning documents or cultural impact assessments, rather the iwi have had opportunities to directly input into the proposal development.
We are satisfied that regard has been given to the impacts on tangata whenua values and interests and provision made for tangata whenua involvement accordingly.

We are satisfied that regard has been given to the impacts on tangata whenua values and interests and provision made for tangata whenua involvement accordingly.
2 The partnership between Council and tangata whenua
An important and relevant Treaty principle is a partnership between tangata whenua and the Crown. In this context providing opportunities for a partnership that gives effect to meaningful engagement and participation in decision-making processes is essential.
The Council has provided for active participation of tangata whenua in the decision-making process through the involvement of tangata whenua representatives on the WMC and WTAG. This partnership provides opportunities to express and implement cultural preferences.
Whilst a partnership does not in itself mean all parties will agree, the evidence provided suggests that all parties are supportive of the application to change the conditions of consent. This is referred to in the application, in sections 5.3 and 6, in describing discussions with Te Runanga o Turanganui a Kiwa and with WMC and WTAG with “the input of tangata whenua being a key consideration” for the proposal.
The conditions of consent and the feasibility programme provide an ongoing role for tangata whenua in the implementation and monitoring of the consents.
We are satisfied that the current proposal to change consent conditions has taken into account the principles of the Treaty of Waitangi.

3 The extent of actual or potential adverse effects on the environment from deferral of the disinfectant treatment process
This has been considered under the three following headings:
ONE Ecological effects:
These are primarily assessed by prediction and monitoring of the following parameters;
Accumulation and bioaccumulation of heavy metals on the sea bed. Sediment organic and chemical characteristics of the sea bed. Diversity and abundance of infauna (the animals living in the sediments of the ocean floor). Metal contamination of crayfish and crabs. Nutrients and ammonia concentrations in the discharged wastewater.
Overall, based on the previous research and recent monitoring results, the applicant’s consultant considers that there will be less than minor adverse ecological effects arising from the proposal.
TWO Recreational health effects:
These are assessed primarily by consideration of the number of enterococci in the discharge wastewater in the ocean water adjoining the discharge location that can be attributed to the wastewater discharge.
Enterococci are bacteria that are indicators of the possibility of pathogens, i.e. disease causing organisms within the wastewater.
The recent assessment of enterococci levels at Location 2 after the BTF found that the discharge contained an average of 67,000 CFU/100ml with a minimum of 4,000 CFU/100ml and a maximum of 340,000 CFU/100ml.
These monitoring results show there is a significant reduction in enterococci levels provided by existing treatment, including by the BTF.
The levels of enterococci levels are, however, greater than the standard of 1,000 CFU/100ml that would be required to be met at Location 4 after the installation of wastewater disinfection.
Analysis of enterococci levels in the receiving environment has also shown a large reduction since commissioning of the BTF. The recreational and water quality assessment recently undertaken has found that:
The mean Enterococci content has reduced significantly across all of the sites monitored as part of the consent following the installation of the BTF.
At the five sites located 500m from the diffuser there appears to be limited influence from the wastewater discharge on the number of indicator organisms.
The applicant’s consultant has assessed the potential adverse public health effects from the discharge. This takes into account the mixing zone surrounding the outfall and background levels of enterococci and other contaminants which are influenced by high sediment and contaminant loadings from the rivers discharging into Poverty Bay.TWO
THREE Amenity effects.
These are related to the visibility of the discharge plume and can be expected to be primarily related to concentrations of suspended solids and oil and grease in the discharged wastewater.
Monitoring of plumes since the commissioning of the BTF has identified a very low incidence of plumes. From the end of 2010, the Council staff member monitoring plumes observed a number of Grade 2 plumes but nothing greater. Grade 2 is a plume just visible but it is contained within the mixing zone allowed in the consent. Since that time, it is understood from the Council’s wastewater staff that there has continued to be a very low incidence of plumes.
Monitoring data shows that suspended solids concentrations already comply with current consent Clause 33 for both before and after commissioning of the preferred long term management option. This is consistent with the applicant’s assessment that the effects of suspended sediment concentrations in the wastewater discharge on the receiving marine environment are minor and no change is proposed to these levels through this proposal.
The effects of total oil and grease (TOG) concentrations in the wastewater discharge on the receiving marine environment which are primarily related to visual effects have been assessed as minor and no change is proposed to these levels through this proposal.
We agree with the above information and assessments following our perusal of the application details and that any adverse effects on amenity will be minor.

Sampling and Analysis
Clause 62
Sampling and analysis shall be carried out by a IANZ registered laboratory or equivalent and procedures shall be in accordance with Standard Methods for the Examination of Water and Wastewater prepared and published jointly by:
American Public Health Association
American Water Works Association
Water Pollution Control Federation, twentieth or newer edition.
Note: Procedures for sieve and screen tests have been developed by the Gisborne District Council and are not registered procedures. These tests have proven very useful in determining effective operation of the existing milliscreens and are considered an effective procedure for use in this permit. Consequently, these tests can continue to be used in terms of these permit conditions.
Sample analysis results shall be provided to the consent authority within 10 days of samples being collected for micro-organism, oil and grease, suspended solids, biochemical oxygen demand, sieve and screen tests or as specifically required in conditions 49 to 61. Any non-compliant results shall be reported to the consent authority as soon as practicable after the sample analysis reveals a non-compliant result, and in any event within 24 hours.
Note: Monitoring frequency and parameters sampled may be reviewed by the WMC, taking advice from the IRP, where appropriate. In the event that the WMC considers changes to monitoring frequency and parameters sampled should be made, it may request the consent authority to consider proposed changes as part of the next review of consent conditions.
Further advice note: In the event of clarification processes being implemented, further conditions are recommended to be sought and amended by way of variation to this permit.
