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.

Telephone: (503) 924-6196

Location: The project site is located at 60371 N. Columbia River Hwy., in St. Helens, Columbia County, Oregon. The site is in Section 32, Township 5 North, Range 1 West. Latitude and Longitude: 45.871334°, -122.823218°.

Waterway: Wetlands A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, Z, AA, BB, CC, DD, EE, FF, OO, PP, QQ, RR, TT, SS, XX, YY, ZZ, and 1-A. Waterways Perennial Stream 1-A, Intermittent Streams B and C, Ephemeral Streams B, C, D and 1-A. The wetland boundaries and/or location of the ordinary high water mark 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 develop a dependable crushed aggregate resource to provide high-quality, cost-competitive aggregate materials to the Portland Metropolitan market.

Project Description: The proposed Watters Quarry Phase II Project involves the expansion of Watters Quarry Phase I (Phase I), an existing active aggregate mining operation. The Phase I quarry is located north of Liberty Hill Road and covers approximately 27 acres. The applicant proposes to expand their existing mining operation south into a 44 acre site to support a combined mining operation totaling 71 acres which can provide a sufficient aggregate source for approximately 50 years.

The applicant would permanently directly impact 10.23 acres of wetland and 0.002 acre of an intermittent waterway through excavation and elimination. The applicant would permanently indirectly impact 1.42 acres of wetlands and 0.058 acre of intermittent waterways from alteration of wetland and stream hydrology; wetlands and waterways indirectly impacted may be completely eliminated over time and, as such, are included in the total permanent aquatic resource impact calculations. The total permanent impact to wetlands would be 11.65 acres and 0.06 acre of intermittent waterways; 0.48 acres of palustrine emergent wetland (PEM), 4.09 acres of palustrine forested (PFO), and 7.08 acres of combined PEM/PFO wetlands would be impacted.

The applicant would remove approximately 16,414,864 cubic yards (cy) of soil and rock to complete the project. The applicant would discharge up to 90,248 cy of soil and rock within wetlands and 4 cy of soil and rock within waterways to complete the project.

The applicant would phase mining operations on the project site through a series of 8 mining stages disturbing only the area needed to produce the volume of aggregate for market demand projected over a 6- to 7-year period. During this time, the remaining land on the project site would remain undisturbed and in its existing condition aside from creation of the proposed on-site compensatory mitigation areas.

The applicant would complete the project utilizing heavy equipment such as bulldozers, excavators, scrapers, and haul trucks. Equipment access to the project site would occur via the Phase I site. Equipment would initially cross Liberty Hill Road into the

Phase II site via a new gravel road connecting the two sites. The applicant may construct an undercrossing beneath Liberty Hill Road constructed to connect the two sites once mining in the northern portion of the Phase II site brings the elevation close to the elevation of the Phase I site. If constructed, this undercrossing would allow for vehicles, equipment, and conveyors to cross between the Phase II site and the processing area at the Phase I site without having to cross Liberty Hill Road.

The applicant would remove the basalt rock with drilling and blasting methods. Once extracted, the rock would be loaded into haul trucks or transported via conveyor to the existing processing crusher at the Phase I location. A rock crusher would be used to crush the rock into different products for stockpiling on site and eventual shipment off site.

The applicant would reclaim the site upon completion of the aggregate extraction at the site in accordance with Columbia County and Oregon Department of Geology and Mineral Industries (DOGAMI) regulations. Reclamation would include creating a lake feature surrounded by native tree, shrub, and herbaceous vegetation suitable for native wildlife habitat. The excavation limits on the project site would be limited by a 200‐foot setback from residential property boundaries and a 50-foot setback from all non-residential property boundaries.

The applicant states aggregate mining at Watters Quarry has been occurring since before 1953. The applicant states they have nearly reached the end of the mineable basalt reserves north of Liberty Road, with only an estimated 2 years of operative life remaining. The applicant is seeking a 50-year Department of the Army permit for the project based on projected stages and market demand for the aggregate.

Mitigation: The applicant proposes to avoid and minimize impacts from the project by

  • Minimizing land use conflicts by locating the project site in an area that that adheres to local zoning regulations and setbacks.
  • Minimizing potential adverse environmental, social and economic impacts on nearby communities by minimizing the amount of noise, dust, air quality, and transportation impacts on nearby communities. The applicant is seeking a project site and design which has a maximum average overburden depth of 20 feet or less to minimize stockpile management and erosion potential, air quality emissions, and associated logistical challenges. The applicant is seeking a project site and design that minimizes disturbance to sensitive species and habitats including forestlands; protected, rare, and sensitive wildlife and plant species; and wetlands and other water resources. In addition, the applicant is seeking a project site and design that avoids and/or minimizes disturbance to any prehistoric or historic remains or indicators of past human activities, including artifacts, sites, structures, landscapes, and objects of importance to a culture or community for scientific, traditional, religious, or other reasons.
  • Implementing ground disturbing activities during drier calendar months to minimize on-site erosion and fine sediment delivery to downstream surface waters;
  • Contouring the area disturbed by mining to ensure stormwater is captured within the mining site; all direct precipitation would be shed internally toward stormwater treatment ponds and then discharged in accordance with a National Pollutant Discharge Elimination System permit for the site;

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 applicant would relocate a perennial stream, sheet flow, and other runoff from adjacent, upslope areas to the proposed compensatory mitigation areas located around the mining area to prevent surface water from entering the mining pit. The applicant proposes to create 18.39 acres of compensatory wetland mitigation, including 1.10 acres of perennial stream creation; the applicant would also enhance existing wetlands through invasives species removal and planting native species. The applicant would create 0.69 acres of PEM wetland and 17.73 acres of PEM/PFO/palustrine scrub-shrub wetlands.

The applicant’s primary objective of the mitigation approach is to replace impacted wetland and stream functions by creating similar habitat to what would be impacted. Wetland habitat types would include wetland forested, scrub-shrub, and emergent communities, including the creation of wet meadow conditions to compensate for similar types of impacted wetlands. Existing upland trees, scrub-shrub, and herbaceous communities on slopes adjacent to the wetlands would provide buffers from quarry activities. The applicant would complete compensatory mitigation prior to or concurrent with the initial discharge of dredged or fill material at the site to monitor success of the mitigation and initiate temporal functional loss replacement.Describe the proposed compensatory mitigation briefly. This should reflect, in summary form, final information submitted from the applicant about compensatory mitigation. The public notice mitigation statement may be used here, but this section should ultimately describe the final, reviewed and accepted, mitigation plan.  The Corps will determine the type and amount of compensatory mitigation necessary to offset environmental losses from the proposed project.

Drawings: Twenty-five (25) drawings are attached and labeled Corps No. NWP-2022-530. 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 Corps previously issued a public notice for this project on February 1, 2021, under Corps No. NWP-2020-65. At the time of the Corps public notice for Corps No. NWP-2020-65, the applicant proposed to expand the aggregate mining operation south, into an area encompassing 131 acres. Within the 131 acre area, 94 acres would be used for aggregate mining and approximately 44 acres would be used for compensatory wetland mitigation. Aggregate mining in the 94 acre area would directly impact 11.38 acres of wetlands and approximately 0.03 acre of intermittent and ephemeral streams. Due to the permanent alteration of hydrology on-site, another 0.85 acre of wetland and 0.03 acre of intermittent streams located along the southern edge of the project area would be indirectly permanently impacted due to the mining operation. Total impacts to wetlands were approximately 12.23 acres and 0.06 acre of intermittent and ephemeral streams.

The applicant subsequently withdrew their previous permit application and has resubmitted their request for a Department of the Army permit for the project with a reduced project scope. 

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.
