8 LANDFILL MANAGEMENT PLAN CONDITIONS ON CONSENTS, 34031, 34032, The consent holder shall prepare an Aftercare Management Plan (AMP) for the site in accordance with the Proposed Auckland Regional Plan: Air, Land and Water (PARP: ALW). An initial draft AMP shall be submitted within 90 days of granting this consent. The final AMP shall be submitted to the Manager and the Peer Review Panel for written approval within six months of the granting of this consent. All provisions of the AMP shall be complied with once approved. The AMP provisions shall be to the satisfaction of the Manager and the Peer Review Panel and can be reviewed should sufficient data be collected to indicate that a change is warranted or if other relevant information comes to light. Any changes shall be approved by the Manager and Peer Review Panel in writing prior to implementation. 2. The Aftercare Management Plan may be reviewed by the consent holder at not greater than yearly intervals. Before completing such a review, the consent holder shall follow the procedures in s.15.0 Community Liaison of the Management Plan and consult concerning the proposed revisions. Thereafter those revisions are to be subject to the approval in writing of the Peer Review Panel and the Group Manager Environmental Management Department, ARC. MONITORING AND CONTINGENCY 3. The Aftercare Management Plan shall describe in detail practices for water and soil chemistry monitoring, shall contain guidelines for the determination of whether contamination is occurring including alert and response levels for individual contaminants, and shall provide contingency plans for remedial actions should leachate contamination occur in any part of the landfill, the groundwater underdrain, groundwater monitoring bores, the stormwater ponds, or the stream on and downstream of the site. 4. The Consent Holder shall ensure that all chemical analyses and sampling techniques are carried out in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater", APHA AWWA WPCE or other standards approved in writing by the Group Manager, Environmental Management Department, Auckland Regional Council. 5. Where any leachate or other pollutants associated with the Consent Holder's operations escapes to natural water other than as authorised under this permit, the Consent Holder shall: a.
