This pamphlet offers information on bioremediation during an oil spill. "Persons seeking to use in-situ bioremediation as a remedial countermeasure should check with applicable state or local regulatory requirements. Federal requirements are in Subpart J of the National Contingency Plan (NCP) which requires the federal On-scene Coordinator (OSC), in the case of an inland release the U.S. Environmental Protection Agency and for a coastal release the U.S. Coast Guard (USCG), to approve the use of bioremediation agents on spills not threatening human life. The federal OSC must have the concurrence of the Region IV Regional Response Team (RRT) for any in-situ bioremediation use unless specifically delegated to a state/local agency."
