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.

30-Day Notice                                       Oregon Department of State Lands No: 62945

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 plans.  The Corps is soliciting comments on the proposed work.
Applicant:    City of North Powder
        Attention: Mr. Mike Wisdom, Mayor
        P.O Box 309 
        North Powder, Oregon 97867
        Telephone: (541) 898-2185

Applicant’s Agent:     Anderson Perry & Associates, Inc. 
        Attention: Dana Kurtz
        P.O. Box 1107
        La Grande, Oregon 97850
        Telephone: (541) 963-8309

Location:  The project site is located east of Highway 237 and north of Miles Ranch Road near North Powder, Union County, Oregon.  The site is in Section 14, Township 6 South, Range 39 East.  Latitude and Longitude:  45.036863° North, 117.902449° West

Waterway:  Wetlands 1, 2, and 3 are on the project site.  The wetland boundaries shown on the project drawings have not yet been verified by the Corps.  If the Corps determines the boundaries of the wetland/waters are substantially inaccurate a new public notice may be published.

Project Purpose:  The applicant’s stated purpose is to address several issues with the existing wastewater system that cause the City to periodically violate the conditions of its NPDES permit.  The purpose of this project is to discontinue wastewater discharge to the Powder River thus eliminating the need to address additional future regulatory restrictions on such discharge.

Project Description:  The proposed project is the Wastewater System Improvements Project.  The project would place a total of 3,490 cubic yards of fill in 0.56 acres of three wetlands to construct a lined evaporative wetland, a transmission pipeline, and a gravel access road.  

    The evaporative wetland impoundment would be approximately 11.5 acres in size and would consist of a low dike impoundment area fitted with an impermeable liner to protect against seepage into groundwater.  Fill would be placed in Wetland 1 to construct the impoundment and would consist of 3,266 cubic yards of soil that is expected to be sourced from the project site as well as 4 cubic yards of liner.  The top 12 inches of existing wetland topsoil would be temporarily removed prior to construction and then placed on top of the liner after construction is complete.

    A transmission pipeline would be constructed from the City’s existing effluent pump station to transfer treated effluent to the proposed evaporative wetland. The pipeline would be installed below grade to allow present farming practices to continue.  161 cubic yards of fill would be placed in Wetland 1 to for the pipeline and appurtenant structures.  An additional 47 cubic yards of fill would be placed in Wetland 1 for a gravel access road in the same alignment as the pipeline.

    Posts for fencing would also be placed in Wetlands 1 and 3 resulting in approximately 8 cubic yards of fill as soil is backfilled into post holes.  The project would not result in any fill being placed in Wetland 2.  

Mitigation:  The applicant proposes to avoid and minimize impacts from the project by flagging regulated work areas, storing equipment in uplands away from these areas, installing sediment barriers and erosion control, and following best management practices (BMP’s).  The applicant has provided a proposed compensatory wetland mitigation plan to offset losses of waters of the U.S. that may result from the proposed project.  The plan consists of the construction of an 0.66-acre on-site mitigation wetland.

Drawings:  Nine (9) drawings are attached and labeled Corps No. NWP-2020-404.  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 select Regulatory Public Notices from the list of Regulatory pages.

Authority:  The proposed project will be evaluated under the following:

    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 soil excavated onsite and commercially available liner, gravel, pipeline and fencing materials.

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.  Attached is the state's notice for a water quality certification.

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 not adversely affect EFH at the project location or in its vicinity.  The Corps will make a final determination on the need to consult on EFH after receipt of comments from this public notice including any comments provided by the NMFS.

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.  

This notice has been provided to the State Historic Preservation Office (SHPO), 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’ Thomas Sentner identified at the end of this notice to assist in a complete evaluation of potential effects.

State and Local Authorizations:  The applicant has obtained approval from Union County and will be applying for the following additional governmental authorizations for the project: Oregon Department of State Lands Removal-Fill Permit and Wetland Delineation Report Concurrence,  Oregon Department of Environmental Quality 401 Water Quality Certification and Water Pollution Control Facility (WPCF) permit, Oregon State Historical Preservation Office Cultural Resource Inventory Report Concurrence.

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; Indian 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.  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.

Submitting Comments:  Interested parties are invited to provide comments on the proposed project.  Comments may be submitted by conventional mail or email.  All comments received will be considered in determining whether authorizing the work would be contrary to the public interest.
