A new Coast Guard proposal that would require tank vessel owners to augment their spill response plans with prearranged salvage and firefighting resources would cost industry nearly half a billion dollars to implement, the Coast Guard estimates. The notice of proposed rulemaking (NPRM), published in the May 10 Federal Register, is intended to stimulate the development of a robust private salvage and firefighting capability in the United States. The NPRM would require holders of approved tank vessel response plans to amend their plans to included pre-contracted access to an extensive suite of salvage and firefighting resources, all capable of being on scene within specified response times.
