This excerpt taken from the MRO 10-K filed Mar 10, 2005.
On May 11, 2001, MAP entered into a consent decree with the U.S. Environmental Protection Agency which commits it to complete certain agreed on environmental projects over an eight-year period primarily aimed at reducing air emissions at its seven refineries. The court approved this consent decree on August 28, 2001. The total one-time expenditures for these environmental projects is approximately $370 million over the eight-year period, with about $240 million incurred through December 31, 2004. In addition, MAP has nearly completed certain agreed on supplemental environmental projects as part of this settlement of an enforcement action for alleged Clean Air Act violations, at a cost of $9 million. MAP believes that this settlement will provide MAP with increased permitting and operating flexibility while achieving significant emission reductions.
