Oil spills: cost of major spills may impact viability of Oil Spill Liability Trust Fund : testimony before the Subcommittee on Federal Financial Management, Government Information, Federal Services, and International Security, Committee on Homeland Securi

"On April 20, 2010, an explosion at the mobile offshore drilling unit Deepwater Horizon resulted in a massive oil spill in the Gulf of Mexico. The spill's total cost is unknown, but may result in considerable costs to the private sector, as well as federal, state, and local governments. The Oil Pollution Act of 1990 (OPA) set up a system that places the liability-up to specified limits-on the responsible party. The Oil Spill Liability Trust Fund (Fund), administered by the Coast Guard, pays for costs not paid for by the responsible party. GAO previously reported on the Fund and factors driving the cost of oil spills and is beginning work on the April 2010 spill. This testimony focuses on (1) how oil spills are paid for, (2) the factors that affect major oil spill costs, and (3) implications of major oil spill costs for the Fund. It is largely based on GAO's 2007 report, for which GAO analyzed oil spill cost data and reviewed documentation on the Fund's balance and vessels' limits of liability. To update the report, GAO obtained information from and interviewed Coast Guard officials. "
