Application for Permit
Issue Date: July 25, 2022
Expiration Date: August 24, 2022
U.S. Army Corps of Engineers No: NWP-1999-172-6
Interested parties are hereby notified the U.S. Army Corps of Engineers, Portland District (Corps) has received an application for a Department of the Army permit for certain work in waters of the United States, as described below and shown on the attached drawings. The Corps is soliciting comments on the proposed work.
Applicant: City of Corvallis
Attention: Chad Marshall
1245 NE Third Street
Corvallis, Oregon 97339
Telephone: (541) 766-6717
Location: The project site is located at 3140 SE Clearwater Drive in Corvallis, Benton County, Oregon. The site is in Township 12 S, Range 5 W, Section 13. Latitude and Longitude: 44.5342 North, 123.2500 West
Waterway: The project is located in the Willamette River at river mile 133.9. The location of the ordinary high water mark shown on the project drawings 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.
Project Purpose: The applicant’s stated purpose is to remove accumulated gravel from the existing water intake structure and screens.
Project Description: The project is the Taylor Water Treatment Plant Water Intake Gravel Relocation project. The project would allow for the City of Corvallis to annually dredge up to 4,500 cubic yards (cy) of gravel from a 0.5 acre area around the existing water intake pipe and screens and place the 4,500 cy of gravel back into the Willamette River over an area measuring 0.46 acres. The gravel is currently at an elevation of 197.0, the proposed dredging would remove gravel to a water depth of 192.0. The gravel is beginning to slow and block water flow into the freshwater intake screens. The project would use a long arm excavator placed on uplands to move gravel away from the screens and place it back into the river channel. Divers would also be used to check the intake screens and remove any remaining accumulated gravels. The work would be completed from June 1 to October 15, annually as needed, when the intake screens are not getting sufficient flows through the screens.
The Corps is evaluating the project for a 10 year permit/authorization.
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.
Mitigation: The applicant proposes to avoid and minimize impacts from the project by working from uplands, use divers, and place the gravel back into the river system. 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: Six (6) drawings are attached and labeled Corps No. NWP-1999-172-6
To access the electronic version of this public notice, go to the Portland District Regulatory website at http://www.nwp.usace.army.mil/Missions/Regulatory and under Regulatory Pages select Permit Application Public Notices.
Additional Information: The site has historically been previously dredged to maintain flows across the intake screens and to minimize buildup of gravels on the screens. The most recent dredging event began on September 9, 2019 and was completed on September 13, 2019. A gravel bar located downstream of the intake has been increasing in size and the thalweg of the river is moving away from the gravel bar. It is anticipated the need to dredge will be evaluated each year and will be based upon the flow pattern and depositional changes in this region of the Willamette River. Gravels placed upstream of the intake are moved downstream by the river during winter flows.
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 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 source of the fill material would be gravel from the Willamette River.
Water Quality Certification: Section 401 of the Clean Water Act (CWA) (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. A copy of this public notice has been provided to the U.S. Environmental Protection Agency (EPA), Region 10. This public notice serves as the Corps’ notification to EPA pursuant to Section 401(a)(2) of the CWA and this notice initiates EPA’s 30-day review period under Section 401(a)(2).
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 an endangered or threatened species or designated critical habitat. The Corps will initiate consultation under Section 7 of the ESA. The Corps will complete the required consultation prior to finalizing a permit decision.
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 the vicinity. The Corps will initiate consultation under Section 305(b)(2) of the MSA. The Corps will complete the required consultation prior to finalizing a permit decision.
Historic Properties/Cultural Resources: Section 106 of the National Historic Preservation Act of 1966, as amended (54 U.S.C. 306108), 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. The Corps’ preliminary review indicates to the best of our knowledge, 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. At this time the Corps is unaware of any cultural resource surveys of the project area.
State and Local Authorizations: The applicant has applied for the following additional governmental authorizations for the project: Removal-Fill Permit from the Department of State Lands (DSL) (DLS No. 46682-RF).
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.
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 proposal 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; Native American Tribes; and other interested parties in order to consider and evaluate the impacts of the 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.
