Section 325 of the 1996 National Defense Authorization Act, Discharges from Vessels of the Armed Forces, requires the Navy to comply with Uniform National Discharge Standards UNDS to control the overboard discharge of incidental wastewaters from ships of the Armed Forces. During Phase I of the UNDS initiative, it was determined that welldeck washout discharges requires a Marine Pollution Control Device MPCD to control the discharge. At the request of Naval Sea Systems Command NAVSEA 05L13, representatives from Naval Surface Warfare Center, Carderock Division Puget Sound Naval Shipyard and AMSEC LLC, conducted shipboard assessments to identify constituents that have the potential to contribute to welldeck washout. The shipboard assessment team conducted three consecutive at-sea assessments aboard a LHD-1 class amphibious assault ship, LPD-4 class amphibious transport dock ship, and LSD-49 class dock landing ship. The ships were conducting a Special Operations Capable Exercise SOCEX and had a full complement of embarked troops, their vehicles and equipment. While aboard the ships, the team observed and documented processes performed in the welldeck, including ballasting and deballasting, and craft launch and recovery. The team interviewed ships force and Marine personnel to obtain information on processes and equipment that have the potential to contribute to welldeck washout discharges. The data obtained during the assessments will be used to develop the MPCD for welldeck washout discharges.
