                        P.O. Box 2946

                        Portland, OR  97208-2946


Applicant:       Port of Astoria

                         10 Pier One, Ste. 308

                         Astoria, OR 97103


Location:        Port of Astoria, Clatsop Co., Ore. (Section 12, Township 8 North, Range 10 West; 46.1884, -123.8591)

Waterway:   Columbia River (River Mile 13)

Project description: The proposed project involves maintenance dredging to restore access and navigation within the Central Waterfront District at the Port of Astoria. The Port had a Corps permit for annual maintenance dredging, but it expired in February 2013. The project would involve  hydraulic and/or mechanical dredging approximately 364,000 cubic yards (cy) of material from Slips 1 and 2 and the face of Piers 1, 2 and 3 initially and approximately 204,000 cy thereafter (over a 5-yr. period). Proposed dredging depths are expected to be maintained between 25 and -45 feet relative to mean lower low water. The Port proposes in-water disposal into the Columbia River navigation channel. Dredge material determined to be unsuitable for aquatic disposal will be disposed at an upland confined disposal facility. The breakdown is as follows:



Proposed depth

Proposed approx. annual volume to be dredged


6.8 acres

-45ft. MLLW

45,000 cy


3 acres

-43 ft. MLLW

22,000 cy


3.5 acres

-43 ft. MLLW

22,000 cy


6.6 acres

-25 to -45 ft. MLLW

60,000 cy initially;

30,000 cy annually


3.2 acres

-45 ft. MLLW

DMMU 5–37,500 cy

DMMU 6–75,000 cy initially; 30,000 cy annually


3.3 acres

-45 ft. MLLW

DMMU 7–37,500 cy

DMMU 8–75,000 cy initially; 30,000 cy annually


2.6 acres

-40 ft. MLLW

DMMU 9–32,500 cy

DMMU 10–65,000 cy initially; 25,000 cy annually


Mitigation: The applicant has not proposed a compensatory mitigation plan because the dredging is expected to have temporary effects to the river. It is expected that the site will continue to accumulate sediment and will not convert shallow-water habitat to deep-water habitat. However, the applicant has proposed several conservation measures to minimize impacts to the aquatic environment.

If a permit is issued, the Corps will determine what is appropriate and practicable compensatory mitigation. The amount of compensatory mitigation required shall be commensurate with the anticipated impacts of the project.

Purpose: To maintain navigable depths at the faces of the piers within the Port boundaries to moor large oceangoing vessels for the purpose of offloading cargo and materials.


Drawings: Three (3) drawings are attached and labeled NWP-2004-369-10 enclosure.


Additional information may be obtained from Jaimee Davis, Project Manager, U.S. Army Corps of Engineers, at 503-808-4390 or email jaimee.w.davis@usace.army.mil.


Authority: This permit will be issued or denied under the following:

             Section 10, Rivers and Harbors Act 1899 (33 U.S.C. 403), for work in or affecting navigable waters of the United States.

             Section 404, Clean Water Act (33 U.S.C. 1344), for discharge of dredged or fill material into waters of the United States.


Water quality certification: A permit for the described work will not be issued until certification, as required under Section 401 of the Clean Water Act (P.L. 95‑217), has been received or is waived from the certifying state. Attached is the state's notice advertising the request for certification.


Section 404(b)(1) evaluation: The impact of the activity on the public interest will be evaluated in accordance with the Environmental Protection Agency guidelines pursuant to Section 404(b)(1) of the Clean Water Act.


Public hearing: Any person may request in writing within the comment period specified in this notice that a public hearing be held to consider this application. Requests for public hearings shall state with particularity the reasons for holding a public hearing.


Endangered species: Preliminary determinations indicate that the described activity may affect an endangered or threatened species or its critical habitat. Consultation under Section 7 of the Endangered Species Act of 1973 (87 Stat. 844) will be initiated. A permit for the proposed activity will not be issued until the consultation process is completed.


Essential fish habitat: The Magnuson-Stevens Fishery Conservation and Management Act, as amended by the Sustainable Fisheries Act of 1996, requires all Federal agencies to consult with the NMFS on all actions, or proposed actions, permitted, funded, or undertaken by the agency, that may adversely affect Essential Fish Habitat.


The project area is within the known range of protected species. The proposed project will have no permanent adverse effects on Pacific salmon, groundfish, or coastal pelagic EFH. We will follow the appropriate course of action under Section 305(b)(2) of the Magnuson-Stevens Act. Any comments the National Marine Fisheries Service may have concerning EFH will be considered in our final assessment of the described work.


Cultural resources: The described activity is not located on property registered or eligible for registration in the latest published version of the National Register of Historic Places. The permit area has been so extensively modified by modern development that little likelihood exists for the proposed project to affect an undisturbed historic property or any other type of cultural resource.


This notice has been provided to the State Historic Preservation Office, interested Native American Indian tribes, and other interested parties. If you have information pertaining to cultural resources within the permit area, please provide this information to the Corps project manager (identified above in this notice) to assist in a complete evaluation of potential effects.


Evaluation: The decision whether to issue a permit will be based on an evaluation of the probable impact including cumulative impacts of the described activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit, which reasonably may be expected to accrue from the described activity, must be balanced against its reasonably foreseeable detriments. All factors, which may be relevant to the described activity will be considered including the cumulative effects thereof; among those are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, consideration of property ownership and, in general, the needs and welfare of the people.


The Corps is soliciting comments from the public; Federal, state, and local agencies and officials; Indian tribes; and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity.


Additional requirements: State law requires that leases, easements, or permits be obtained for certain works or activity in the described waters. These state requirements must be met where applicable, and a Department of the Army permit must be obtained before any work within the applicable Statutory Authority previously indicated may be accomplished. Other local governmental agencies may also have ordinances or requirements, which must be satisfied before the work is accomplished.
