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.
