A key federal report lays much of the blame on BP for the worst offshore oil spill in US history and the deaths of 11 rig workers, particularly with regard to the cement seal that was put in place the day before the explosion that triggered the spill. The report, released today, said in the days leading up to the disaster, BP made a series of decisions that complicated cementing operations, added risk, and may have contributed to the ultimate failure of the cement job. The details were contained in the final report from the Coast Guard and the agency that regulates offshore drilling, the Bureau of Ocean Energy Management Regulation and Enforcement.

The report comes to similar conclusions as previous investigations, but it is likely to carry more weight in Congress, where Republican lawmakers in particular have said they are unwilling to adopt reforms until the federal inquiry was complete.
