EPA and DoD are promulgating discharge performance standards for 11 discharges incidental to the normal operation of a vessel of the Armed Forces in the navigable waters of the United States, the territorial seas, and the contiguous zone. When implemented, the discharge performance standards will reduce the adverse environmental impacts associated with the vessel discharges, stimulate the development of improved vessel pollution control devices, and advance the development of environmentally sound vessels of the Armed Forces. The 11 discharges addressed by the final rule include the following: Catapult water brake tank and post-launch retraction exhaust, controllable pitch propeller hydraulic fluid, deck runoff, firemain systems, graywater, hull coating leachate, motor gasoline and compensating discharge, sonar dome discharge, submarine bilgewater, surface vessel bilgewater/oil-water separator effluent, and underwater ship husbandry. This final rule is effective on 17 August 2020. POC is Katherine B.
