The Commission authorized staff to file a motion in federal district court to prevent the merger of BP Amoco p.1.c. and Atlantic Richfield Company. The complaint, filed in the U.S. District Court for the Northern District of California, alleged that the merger would reduce competition in the exploration and production of Alaska North Slope crude oil and its sale to West Coast refineries, and in the market for pipeline and storage facilities in Cushing, Oklahoma. Under the terms of the order, BP Amoco was required to divest all of ARCO's assets relating to oil production on Alaska's North Slope (ANS) to Phillips Petroleum Company or another Commission-approved purchaser. BP Amoco also would have to divest all ARCO assets related to its Cushing, Oklahoma crude oil business within four months.
