A historic settlement announced today with the Kerr-McGee Corporation and certain of its affiliates and their parent Anadarko Petroleum Corporation will greatly benefit environmental cleanups at superfund sites and reimburse the federal government for substantial cleanup costs. The defendants agree to pay $5.15 billion to settle the case, of which approximately $4.4 billion will be paid to fund environmental clean-up and for environmental claims. This is the largest environmental enforcement recovery ever by the Department of Justice.
