Shoreline clean-up

Workers cleaning the beaches at Fourchon, Louisiana - May 2010

The extensive shoreline clean-up operations were directed by the U.S. Coast Guard’s federal on-scene coordinator and guided by technical assessments by multi-party assessment teams.

From the beginning of the Deepwater Horizon response, shoreline clean-up assessment technique teams – comprised of scientific experts and federal and Gulf state representatives –­ systematically surveyed the shoreline to assess oiling conditions and develop shoreline treatment recommendations, which were implemented at the direction of the U.S. Coast Guard’s federal on-scene coordinator (FOSC).

Assessment teams found that of the approximately 4,400 shoreline miles that were ground-surveyed, around 1,100 miles experienced some level of oiling and some measure of mechanical or manual cleaning was recommended for 776 miles.

The Coast Guard ended active clean-up operations on the final few shoreline miles in Louisiana in April 2014 and transitioned them to the National Response Center (NRC) reporting process. This ended active clean-up in the Deepwater Horizon area of response and followed the mid-2013 transition of Alabama, Florida and Mississippi to the NRC process. BP remains committed and prepared to respond at the direction of the Coast Guard if further Macondo oil is identified through the NRC process and requires removal.

National Response Center

The NRC serves as the national point of contact for reporting all oil discharges into the environment anywhere in the U.S. and its territories. The Coast Guard investigates reports of oil received by the NRC and identifies the source.

Sightings of possible oil or oil-based material can be reported to the NRC at 1-800-424-8802 or a report can be filed at

Scientific studies of residual oil

Scientific studies conducted by the Operational Science Advisory Team (OSAT) have assessed the state of the environment following the Deepwater Horizon oil spill and the potential impacts of residual oil.

The reports played a critical role in guiding clean-up operations by providing a scientific understanding of the fate of the oil and the potential effect on people and the environment.
