Environmental, Engineering and Land Use Issues: Significant Habitat: The portion of Sand Island to the south of the site contains significant examples of native dunegrass communities and has been proposed for designation as a national natural landmark. Dredged material disposal shall not occur south of the designated site. There is a concern about non-native plan species encroaching upon the native dunegrass communities. Revegetation of the site shall be restricted to plant species and planting techniques that will not negatively impact the native dunegrass communities. Sequence of Site Use: This is the first priority pipeline disposal site for Baker Bay West Channel. W-3.0 should be used after O-3.1 is filled. Special Conditions on Use (include but not limited to): 1. No material shall be placed beyond the boundaries depicted on the map of O-3.1. These boundaries are defined by aquatic areas to the north and west, the southern containment levee existing as of 1986 to the south (this outlines the northern limit of a proposed national natural landmark), and the containment levee existing as of 1986 to the east. 2. The site shall be revegetated as soon as practicable after disposal. The revegetation plan shall be coordinated with the agency responsible for overseeing the national natural landmark (or The Nature Conservancy if the landmark designation has not been made) to ensure that plant species and planting techniques do not adversely impact the native dune communities.

Environmental, Engineering and Land Use Issues: Caspian Tern Nesting Colony: A nesting colony of Caspian terns utilize the site from about mid-May to the end of July. Because terns nest in open sand, it is preferable not to revegetate the site after disposal. Disposal shall be timed to allow an adequate period for the site to de-water prior to the nesting season. Gull Nesting Colony: Western and Glaucous-winged gulls use the site as a nesting colony. Restrictions on Designated Project and Type of Material: This site is reserved for fine-grained materials dredged from the northern portion of Chinook Channel only. Site O-5.8 is reserved for coarse-grained material removed by pipeline dredge from Chinook Channel. Special Conditions on Use (include but not limited to): 1. The site shall not be expanded beyond its January 1986 boundaries as depicted on the map. 2. The containment levee shall be constructed from material obtained from within the existing disposal site. This material shall be placed on top and/or inside of the existing levee surrounding the site. No material shall be placed beyond the outside toe of the existing levee. 3. Care shall be taken not to disturb the vegetation on the outside face of the existing levee. 4. The timing of dredged material disposal shall be determined in coordination with state and federal fish and wildlife management agencies to minimize impacts to nesting Caspian Terns and Western Glaucous winged gulls and other resources affected by the dredging.

Environmental, Engineering and Land Use Issues: Wetlands: The site may contain non-tidal wetlands that fall within Federal Section 404 or Oregon State Removal-Fill permit jurisdictions. Prior to undertaking disposal, the Corps and Oregon DSL must be consulted to determine if the site contains wetlands within their respective regulatory jurisdictions. If regulated wetlands are present at the site, the dredging project proponent will be required to either adjust the disposal site boundaries to avoid the wetlands and provide an adequate buffer or obtain Federal and State approval to fill the wetlands. The federal and state agencies may require the dredging project proponent to mitigate for the lost wetland as part of the approval for the fill. Owner Coordination: A Coast Guard station is adjacent to the southern portion of the site. Use of the site should not interfere with the station. The northern portion of the site is within Fort Stevens State Park. Disposal at the site will need to be coordinated with the Coast Guard and Fort Stevens State Park. Special Conditions on Use (include but not limited to): 1. Prior to undertaking disposal, the dredging project proponent shall consult with the Army Corps and Oregon DSL to determine if the disposal site contains wetlands that are regulated under permit programs administered by those agencies. If the site contains regulated wetlands, the dredging project proponent shall either alter the disposal site boundaries to avoid the wetlands and leave an acceptable protective buffer, or obtain the necessary Corps and DLS permits to fill the wetlands. 2. The dredging project proponent shall coordinate site preparation and disposal plans with Coast Guard and Fort Stevens State Park representatives.

Environmental, Engineering and Land Use Issues: Commercial Fishery: The disposal site is within a gillnet and crab fishing area. Prior to undertaking disposal, the dredging project proponent will be required to contact the local fishermen's associations and the state fishery agency to determine project timing and disposal methods that will minimize impacts to the fisheries. Juvenile Salmon: Juvenile salmon migrate through and adjacent to the site. The dredging project proponent will be required to consult with the state fishery agency, the National Marine Fisheries Service, and U.S. Fish and Wildlife Service to determine project timing and disposal methods that will minimize impacts to juvenile salmon Area D Use: The use of Area D shall be kept to an absolute minimum. The shoaling problems that result from dredged material disposal at Area D present an ongoing concern in the estuary. A large portion of the material deposited at the site moves upriver and is eventually redeposited in the navigation channel. A smaller portion of the Area D material moves into Baker Bay and is deposited. The COE should continue to examine alternative disposal sites and methods that would result in fewer adverse shoaling impacts. The use of Area D shall be discontinued when feasible alternatives are found. Special Conditions on Use (include but not limited to): 1. Dredged disposal at Area D shall be allowed for the following Corps dredging projects and sites: Chinook Channel and Baker Bay West Channel. Non-federal projects proposed in estuarine locations between the mouth of the Columbia River and Tongue Point may also be eligible for disposal in Area D, provided they meet the policies and standards for estuarine in-water disposal. 2. Total disposal for COE projects at Area D shall not exceed 3,250,000 cubic yards over a 5 year period. 3. Total annual disposal for non-federal projects shall not exceed 100,000 cubic yards. 4. Disposal shall be controlled so as to minimize impacts to commercial gillnet and crab fishermen. 5. Prior to undertaking disposal, the dredging project proponent shall consult with the state fishery agency, National Marine Fisheries Service, and U.S. Fish and Wildlife Service to determine project timing and disposal methods that will minimize impacts to juvenile salmon
