Abstract: This Environmental Assessment (EA), prepared by the U.S. Army Corps of Engineers, Portland District (Corps), is being submitted for public review under applicable laws and regulations, including the National Environmental Policy Act (NEPA). The purpose of this EA is to evaluate the effects of expansion of the nearshore dredged material placement site used for the Operations and Maintenance (O&M) program for Port Orford Federal Navigation Project. The purpose of the Port Orford Federal Navigation Project is to provide a continuous, safe, reliable commercial shipping channel by periodically removing unsafe and restricting shoals. In order to maintain the channel at its authorized depth (16 feet), material from maintenance dredging is placed in water at the nearshore placement site, approximately 200 feet off the edge of the breakwater. Management of dredged material is dependent on geographic and temporal variability of shoal development within the Port Orford Federal Navigation Project, and dredged material placement is implemented strategically at the nearshore site to balance placement and dredging needs. The need for expanded placement is recognized as a key element for successful continual maintenance of the Port Orford Federal Navigation Project. The action would double the dredge placement area, expanding the southern boundary of the existing placement area by approximately 800 feet to the south. The project action would be implemented after the Corps has received all required environmental clearances, and if the Corps makes a Finding of No Significant Impact (FONSI) for the Proposed Action. The Corps is the lead federal agency for this EA.
