8.4 Waste management plan The project will seek to minimise the amount of waste material transported from the Derby shore-base to the site. Garbage generated on the site will include empty feed bags, staff domestic waste and, old ropes and net mesh. All non perishable garbage will be packed into empty one tonne bulk bags and brought back to Derby for disposal. Perishable garbage will be stored in sealed containers and stored for disposal in Derby. The operation will generate a small quantity of used oil from engine servicing which will be stored in a 44 gallon drum and capped, and returned to Derby for disposal. MPA will provide bunding for all oil, fuel, silage and other chemicals stored on Turtle Island. Sewage will be either treated for disposal at sea using an approved (by DoF and DEC) toilet treatment system, or stored in tanks on the accommodation vessel and pumped out for disposal when the vessel is in port. Fish mortalities will be removed from the cages two times per week and will be minced and stored in sealed drums as silage. The silage units use formic acid to liquefy fish waste and are commercially available. Fish silage equipment is in common usage on fish farms worldwide. The silage will be removed from the site when required and transported to Derby for reuse, or disposal if no use can be found. 8.5 Decommissioning plan Should the operation be discontinued the infrastructure will be removed from the site. To achieve this, the following operations will be performed: � All fish will be harvested; � Fish nets will be stripped from the cages and taken to Derby; � Cages will be towed back to Derby and dismantled; and � Moorings will be removed and transported back to Derby. It is acknowledged that the decommissioning of aquaculture sites if not undertaken by the proponent, is completed by the Department of Fisheries with any costs incurred, recouped through legal means if necessary (pursuant to Fish Resources Management Regulations 1995 (FRMR)).
