The final EIS provides information to support designation of an ocean dredged material disposal site (ODMDS) in the Pacific Ocean off the mouth of the Coquille River in the state of Oregon. The proposed ODMDS is an adjusted location lying north-northeast of an existing, interim-designated site. Site designation studies were conducted by the Portland District, Corps of Engineers, in consultation with Region 10, EPA. The adjusted ODMDS was judged to be a safer location with less potential for adverse environmental effects. No significant or long term adverse environmental effects are predicted to result from designation. The designated ODMDS would continue to receive sediments dredged by the Corps of Engineers to maintain the federally authorized navigation project at Coquille River, Oregon, and other dredged materials authorized in accordance with Section 103 or the Marine Protection, Research, and Sanctuaries Act of 1972 (MPRSA). Designatin of an ODMDS does not constitute or imply approval of an actual disposal of material. Before any disposal may occur a specific evaluation by Corps must be made using EPA's ocean dumping criteria. EPA makes an independent evaluation of the proposal and has the right to disapprove the actual disposal.
