"Congressional Republicans allowed a tax on oil companies that generated hundreds of millions of dollars annually for federal oil-spill response efforts to expire this week — a move that amounts to another corporate break in the wake of lawmakers’ sweeping tax overhaul late last month.

The tax on companies selling oil in the United States generated an average of $500 million in federal revenue per year, according to the Government Accountability Office. The money, collected through a 9 cents-per-barrel tax on domestic crude oil and imported crude oil and petroleum products, constituted the main source of revenue for the Oil Spill Liability Trust Fund.

The fund has at least $5.75 billion in reserve. Intended to help the government respond quickly to accidents on land or offshore, it was established in 1986 but only got a stable source of funding in the wake of the 1989 Exxon Valdez spill."
