Descriptive Specification

1. This consent authorises the discharge of treated wastewater from the Tokomaru Wastewater Treatment Plant (WWTP) to ground and to surface water (Centre Drain) at and on a property legally described as Lots 1 & 2 DP 45200 (hereafter referred to as the property or site) at approximate map reference NZTopo50 BM34 119 165.

2. The Consent Holder must undertake the activity in general accordance with the consent application including all accompanying plans and documents first lodged with the Manawatū-Whanganui Regional Council on 22 July 2016 and further information as set out in Good Earth Matters Consulting Limited's letter dated 12 September 2016, or any modified plan to which the Manawatū-Whanganui Regional Council has given prior written approval. Where there is any contradiction between the information contained in the abovementioned documents and these consent conditions, the consent conditions must take precedence.

3. Wastewater must be treated via an oxidation pond and wetland area with normal discharge being to ground via the base of the wetland area. When flows exceed the capacity for discharge to land via the wetland, discharge of treated wastewater must be to Centre Drain.

4. The discharge of treated wastewater to Centre Drain must not exceed 250 m3/day. averaged over any continuous seven day period.

5. The discharges authorised by these Consents must not:

a. cause the production of any conspicuous oil or grease films, scums or foams, or floatable or suspended materials; or

b. cause any emission of objectionable odour; or

c. render water unsuitable for consumption by farm animals; or

d. cause any significant adverse effects on aquatic life

in Centre Drain after reasonable mixing defined at the Site 3b Monitoring Point as shown on Plan ATH- 2002008648.02 A.

6. The quality of the treated wastewater discharged to Centre Drain must not:

a. Have a concentration of ammoniacal-nitrogen (NH4-N) exceeding 20 g/m3;b. Have a total CBOD5 (five-day carbonaceous biological oxygen demand) exceeding 70 g/m3;

andc. Have a suspended solids concentration exceeding 150 g/m3.

7. The quality of ammoniacal-nitrogen (NH 4-N) as measured at Site 3B downstream of the wetland must not exceed 0.4 g/m 3 on an annual average and/or 2.1 g/m 3 as an instantaneous maximum .

ADVICE NOTE: Ammoniacal nitrogen toxicity must be assessed after correcting for pH as measured instream at the time of sampling.

ADVICE NOTE: The annual average of ammoniacal-nitrogen (NH 4-N) is based on the last 12 months of data inclusive of those months when there has been no discharge.

Flow Metering & Recording

8. The Consent Holder must ensure that fully operational and calibrated flow meters are maintained at the following locations:

Monitoring

22. The Consent Holder must, no less than monthly, collect the following samples and have them analysed for the parameters specified in Condition 25:

a. A representative sample from the inflow to the WWTP (Site 1a);b. A representative sample from within the outflow from the oxidation pond to the Wetland

31. The Consent Holder must review the Operations and Risk Management Plan on an annual basis and update the Plan as necessary to ensure it continues to meet the requirements set out in Condition 30. As part of this review, the consent holder must consult with adjoining landowners as to the effectiveness of nuisance wildlife management actions and any changes required to achieve effective management of pest species.

32. Where there are changes made to the Operations and Risk Management Plan as a result of the annual review required under Condition 31, the Consent Holder must provide the Manawatū-Whanganui Regional Council and members of the TWWWP with a copy of the updated Operations and Risk Management Plan within 20 working days of the update being completed.

Consent Attachment 2: Tokomaru Wastewater Working Party

1. GENERAL

This document sets out the terms of reference for the Tokomaru Wastewater Working Party (TWWWP) to enable the Horowhenua District Council (Council) to meet Conditions 13 - 15 of Discharge Consents ATH-2002008648.02 (Water), ATH-2002008649.02 (Wetland), and ATH-2016200987.00 (Air).

Council has sought a five-year term of consent for the Tokomaru Wastewater Treatment Plant (WWTP) discharges in order for improvement and investigation works prior to adopting the planned long-term disposal to land solutions. During the term of consent, the Council will:

Complete works to minimise groundwater entering the treatment plant (lining of oxidation pond);

Undertake investigations and repairs where appropriate to minimise stormwater entering the wastewater reticulation; and

Undertake and complete specific milestones in preparation for the planned long-term sustainable treatment and disposal to land options.

Submitters to the consent process sought a means of effective engagement with the Council during the term of consent in order to have input into the consideration of effects of the discharges and to the selection of a sustainable long-term solution, which has since been confirmed by the Council as a planned long-term sustainable treatment and disposal to land options with contingency disposal to surface water (Centre Drain), to minimise discharge to surface water as far as practicable.

The TWWWP has been established to provide a means for this engagement.
