Abstract:
Following discussions with Northumberland County Council on the 18th of August, 1994, the NRA agreed to carry out further monitoring work in relation to proposed clean-up operations in the vicinity of Battleship Wharf where estuary sediments are severely contaminated with PCBs. MAFF have agreed a 200 microg/kg (200ppb) concentration in dredge spoil as permissable for disposal of dredgings at sea, with sediments above this limit being unacceptable for sea disposal. NRA have agreed that sediments above this level should be removed from the estuary for land-based disposal. The County Council is proposing to dredge contaminated sediment above the 200 microg/kg level from the estuary for encapsulation on reclaimed land at Battleship Wharf. The removal of contaminated sediment should result in significant environmental improvements to the estuary and remove the threat of PCB accumulation in marine food chains. A three phase monitoring plan was proposed covering the period of the clean-up (Appendix 1). This report is an interim report covering Phase 1 of the monitoring plan.
