WASTE MANAGEMENT – ENVIRONMENTAL COMPLIANCE
Changes to the environmental protection legislation as a result of the Protection of the Environment Legislation Amendment Act 2011 requires all local Councils to publish groundwater, surface water, leachate and landfill gas monitoring data from each of their landfill sites from 1 July 2012.
Nambucca Council currently operates two sites adjacent to each other within the LGA being a landfill and transfer station.
Licensed Facility: Nambucca Waste Management Facility
Environment Protection Licence: No 11386 (Landfill) & No 6268 (Transfer Station)
Facilities Address: 711 Old Coast Road Nambucca Heads
Licensee's Name: Nambucca Valley Council
Licensee's Address: PO Box 177, Macksville NSW 2447
