Permit Application Public Notices

The United States Congress authorizes the U.S. Army Corps of Engineers to regulate activities that may impact wetlands and waters of the United States. This authority is granted and defined under Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Federal Water Pollution Control Act Amendments of 1972, also known as the Clean Water Act.

Public involvement is a key element of the Corps’ permit review process. During an application review, the Corps considers the views of other federal, state and local agencies, Native American tribes, interest groups, and the general public. The results of this careful public interest review are fair and equitable decisions that allow reasonable use of private property, infrastructure development, and growth of the economy, while offsetting the authorized impacts to the waters of the United States.

Location: The project site is located at the U.S. Coast Guard Marine Safety Unit Portland (USCG MSU Portland), 6767 North Basin Avenue, in Portland, Multnomah County, Oregon. The site is in Section 17, Township 1 North, Range 1 East. Latitude and Longitude: 45.57° North, -122.72° West.

Waterway: The Willamette River and Swan Island Basin at River Mile 7.5. The location of the ordinary high-water mark (OHWM) has not yet been verified by the Corps. If the Corps determines the boundaries of the waters are substantially inaccurate a new public notice may be published. The project is located within the Portland Harbor Superfund Site (PHSS).

Project Purpose: The applicant’s stated purpose is to complete maintenance dredging activities to safely maintain operational design depths, including 2 feet of over depth for USCG vessels, at the USCG MSU Portland.

Project Description: The applicant is proposing to perform maintenance dredging at the USCG MSU Portland basin within the Willamette River and Swan Island Basin. The applicant would dredge up to a total of 3,000 cubic yards (cy) of sediment from below the OHWM of the Willamette River over two dredging events within a 10-year period.

An initial dredge event would remove 160 cy of sediment from the 685-square-foot basin in the western dredge area and 398 cy of sediment from the 4,243-square-foot basin in the eastern dredge area. The basin would be dredged to a maximum depth of -12 feet Columbia River datum (CRD) which includes a 2-foot over dredge allowance.

Post dredge surface management will be determined by the dredged material evaluation per the Clean Water Act (CWA) and in coordination with the U.S. Environmental Protection Agency’s (USEPA) per the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) requirements for the PHSS. The applicant may discharge up to 100 cy of clean sand below the OHWM of the Willamette River to create a one-foot sand cover after reaching -12 feet CRD depth to temporarily contain potential contamination from the post-dredge surface layer. The need for a sand cover, post-dredge sampling, or monitoring is contingent on the outcome of the CWA dredged material evaluation as described below.

The applicant would complete the dredging activity using either a mechanical clamshell method or a hydraulic method, such as suction dredging, that would send the material via pipe to a barge to contain excavated materials. The excavated material would be placed on the deck of the barges and dewatered using barge scuppers and filtration, then transported to the upland disposal site via truck. Barges would be assembled and docked when not in use on the shore on the downstream side of the USCG MSU Portland.

In addition to the event described above, a second event would be conducted if sediment in-fill occurs within the dredge area more quickly than anticipated. The additional dredge event would dredge up to 2,442 cy of sediment from the basin. The work would be conducted using mechanical or hydraulic dredging to a depth of -12 feet CRD which includes the 2-foot over dredge allowance.

Dredged Material Testing: The proposed dredged material will be evaluated in accordance with the Sediment Evaluation Framework for the Pacific Northwest (SEF). The interagency Portland Sediment Evaluation Team (PSET) implements the SEF for the Corps Portland District. The PSET will determine if sediment testing is required for this project. Project sediments may require physical, chemical, and/or biological testing to support the permit application evaluation. The PSET will evaluate the applicant’s sediment testing results and determine if project sediments are suitable for unconfined, aquatic disposal and exposure.

The proposed project includes future maintenance dredging. Prior to each maintenance dredging cycle, the applicant would be required to coordinate with the Corps and the PSET to determine if additional sediment testing is required.

Mitigation: The applicant proposes to avoid and minimize impacts from the project by implementing a pollution control plan, deploy floating silt curtains where necessary and deploy a spill response protocol if needed. All foreign and dredged materials will be disposed of properly in uplands and stored at least 150 feet from a waterbody and contained within an isolated zone. Dredging will be conducted from a barge to avoid land-based activities that could affect riparian communities.

The applicant did not propose compensatory mitigation in the permit application. The Corps will determine the type and amount of compensatory mitigation necessary to offset environmental losses from the proposed project.

Drawings: Four (4) drawings are attached and labeled Corps No. NWP-2013-172-1. Copies of this public notice, which have been mailed or otherwise physically distributed, feature project drawings in black and white. The electronic version features those drawings in color, which we think more accurately illustrates the proposed project. To access the electronic version of this public notice, go to the Portland District Regulatory website at and under Regulatory Pages select Permit Application Public Notices.

Additional Information: The work would be completed over a 10-year period. The past permit action for the related maintenance dredging in USCG MSU Portland is NWP-2013-172.

Authority: The proposed project will be evaluated 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 14, Rivers and Harbors Act 1899 (33 U.S.C. 408) (referred to as “Section 408”), for work to alter a Corps civil works project. An alteration is defined as any action that builds upon, alters, improves, moves, occupies or otherwise affects the usefulness, or the structural or ecological integrity of a Corps federally authorized project. The proposed project may alter the Willamette River Navigation Channel.

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

Clean Water Act Section 404(b)(1) Guidelines: The described discharge will be evaluated for compliance with guidelines promulgated by the U.S. Environmental Protection Agency under authority of Section 404(b)(1) of the Clean Water Act. The 404(b)(1) Guidelines are the substantive criteria used in evaluating discharges of dredged or fill material into waters of the United States. The Corps will evaluate the fill material source (i.e., borrow site) prior to finalizing a permit decision.

Water Quality Certification: Section 401 of the Clean Water Act (33 U.S.C. 1341) requires applicants to obtain a water quality certification for proposed discharges into waters of the United States. A permit for the described work will not be issued until certification has been issued or is waived from the certifying state. The state’s notice for a water quality certification is attached.

Endangered Species: Section 7 of the Endangered Species Act (ESA) (16 U.S.C 1536) requires federal agencies to consult with the National Marine Fisheries Service (NMFS) and/or U.S. Fish and Wildlife Service (USFWS) on all actions that may affect a species listed (or proposed for listing) under the ESA as threatened or endangered or that may adversely modify designated critical habitat. The Corps’ preliminary review indicates the described activity may affect any endangered species or designated critical habitat. For this project, the United States Coast Guard, as the lead Federal agency for ESA consultation, will consult with the NMFS and/or the USFWS as required under Section 7 of the ESA.

Essential Fish Habitat: Section 305(b)(2) of the Magnuson-Stevens Fishery Conservation and Management Act (MSA) as amended (16 U.S.C 1855), requires 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 (EFH). The Corps’ preliminary review indicates the described activity would adversely affect EFH at the project location or in its vicinity. For this project, the United States Coast Guard, as the lead Federal agency for MSA consultation, will consult with the NMFS as necessary.

Historic Properties/Cultural Resources: Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended (16 U.S.C. 470), requires Federal agencies to consult with the appropriate State and/or Tribal Historic Preservation Officer to take into account the effects of actions they undertake or permit on historic properties listed in or eligible for listing in the National Register of Historic Places. For this project, the United States Coast Guard, as the lead Federal agency for determining compliance with Section 106 of the NHPA, will consult with the appropriate State and/or Tribal Historic Preservation Officer as applicable.
