The Obama administration unveiled plans last night to divide the government agency that oversees offshore drilling operations. The plan would split the Minerals Management Service into two agencies, one to oversee the safety of offshore drilling projects, the other to collect drilling royalties each year. Interior Secretary Ken Salazar said the move was needed to guarantee there is no conflict in the duties of the agency. The Minerals Management Service has come under intense scrutiny following the massive BP oil spill in the Gulf of Mexico. The MMS had exempted BP from a comprehensive environmental review of the project that resulted in the spill.
