The Coast Guard, Delaware Department of Natural Resources and Environmental Control (DNREC) and the New Jersey Department of Environmental Protection (NJDEP) continue to lead the recovery and clean-up of oil spilled in the upper Delaware Bay. As a preventive measure, the NJDEP has closed 70,000 acres of New Jersey's oyster beds to prevent potential environmental contamination. The Captain of the Port of Philadelphia has also issued a safety broadcast to mariners informing them of the obstructions to navigation due to the deployment of protective booming. Under direction of the Captain of the Port, protective booming which will limit or prohibit access to waterways has been placed in Back Creek, Nantuxet Creek, Fortescue Creek and Dividing Creek on the New Jersey side of the Delaware Bay.
