MMS published a Federal Register notice on April 2 requesting comments on the Preliminary Revised 2007-2012 Five-Year OCS Oil and Gas Leasing Program for lease sales covering the 2007-2012 timeframe. The comment period will be open through May 3, 2010. The Preliminary Revised Program was required by order of the U.S. Court of Appeals for the District of Columbia in Center for Biological Diversity v. U.S. Dept. of Interior. The Revised 2007-2012 Plan includes an expanded environmental sensitivity analysis and re-affirms the role of the Gulf of Mexico as the primary producing region, retaining the eight sales that have already occurred there and the four remaining on the schedule. However, regarding development off of Alaska, the Revised Plan schedules no lease sales in the North Aleutian Basin or Beaufort Sea, and none in the Chukchi Sea other than Sale 193 (which took place in 2008).
