The report provides background information on the problem of waste disposal for ships, reviews the Environmental Protection Agencys proposed secondary treatment standard for marine sanitary devices, and recommends an alternate standard for U.S. Navy ships. The alternate standard is based on environmental management considerations it would permit Navy ships to discharge raw sewage overboard while in transit but would require all sewage, human and domestic, to be pumped ashore while ships are moored at Naval Stations. Under the alternate standard the contribution of Navy ships to biological oxygen demand and suspended solids in United States harbors would be reduced by approximately 95 percent, whereas the EPA standard will achieve a reduction of less than 70 percent. In addition the alternate standard would reduce by an estimated 68 percent or 19.7 million dollars annually the planned cost to the Navy of meeting the EPA standard by installing a sewage holding system on naval ships.
