Discharge permit

Washington, D.C., June 20, 2007 -- The Environmental Protection Agency (EPA) is seeking information as it considers how to develop a water permit program for pollutant discharges incidental to the normal operation of commercial vessels and recreational boats. Discharges may include ballast water, bilge water, deck runoff and gray water.

As a result of a court ruling currently under appeal, vessel owners or operators whose discharges previously have been exempt from Clean Water Act requirements will require a permit on Sept. 30, 2008. In developing this program, EPA will seek to ensure that control technologies or management practices enhance environmental protection and are practical to implement.

Approximately 143,000 commercial vessels and potentially more than 13 million state-registered recreational boats and more than 25 different types of vessel discharges could be affected. The exemption from permitting requirements has been in place for more than 30 years.

The changes are the result of a recent U.S. district court ruling that found EPA exceeded its authority by excluding discharges incidental to the normal operation of a vessel from existing permitting requirements. The agency is appealing that ruling.
