(This measure has not been amended since it was introduced. The summary of that version is repeated here.)
Makes permanent a provision which prohibits the Environmental Protection Agency (EPA) from requiring a National Pollutant Discharge Elimination System permit under the Federal Water Pollution Control Act (commonly known as the Clean Water Act) for a vessel that is less than 79 feet in length or a fishing vessel for any discharge: (1) of effluent from properly functioning marine engines; (2) of laundry, shower, and galley sink wastes; or (3) that is incidental to the normal operation of those vessels. (Currently, the prohibition is temporary and the time period in which the EPA is prohibited from requiring a NPDES permit ends on December 18, 2014. This prohibition does not apply with respect to garbage discharged overboard, other discharges when the vessel is operating in a capacity other than as a means of transportation, discharges of ballast water held in ships to increase stability, or any discharge that contributes to a violation of a water quality standard or poses an unacceptable risk to human health or the environment.)
