I refer to your information request of 6 April 2020 for the Resource Consent held by the WWTP for the discharge of sludge or biosolids, and any associated air discharge consents. Your request was processed under the Local Government Official Information and Meetings Act.

WWTP composting operation - RLC

Attached are:

• RC 66424 - Discharge of Contaminants to land from composting facility at WWTP. This RC is not due to expire until 31 October 2024 but was surrendered in 2014 when RLC stopped the composting operation.
• RC 67630 - Discharge of contaminants to air from the Te Ngae Road composting facility. This RC is not due to expire until 31 October 2023. This has not been surrendered and still operational.

After RLC stopped the composting operation, Ecocast were contracted to manage the disposal of biosolids from the WWTP through a vermicasting operation. This operation is authorised by two resource consents. Both consents have included odour control/management requirements.

Attached are:
