Summary

On January 14, 2026, EPA received a request from the Idaho Department of Parks and Recreation for a water quality certification for the Chatcolet Lake Boat Launch Project [U.S. Army Corps of Engineers Walla Walla District project number NWW-2012-57].

Section 401(a)(1) of the Clean Water Act requires applicants for federal permits and licenses that may result in discharges into waters of the United States to obtain certification that the discharge will comply with applicable provisions of the Clean Water Act. Where no state agency or Tribe has authority to give such certification, EPA is the certifying authority.

In this case, the proposed project is within a portion of the Coeur D’Alene Reservation in which the Coeur D’Alene Tribe does not have treatment as a state under Clean Water Act Section 401. Therefore, EPA is the certifying authority for this proposed project.

According to the application, the Idaho Department of Parks and Recreation proposes to impact wetlands and waters in order to improve an existing boat launch facility. The project is located in Chatcolet Lake in Benewah County, Idaho (latitude 47.372688, longitude -116.761697).

EPA is requesting comments on its Clean Water Act Section 401 water quality certification for this proposed project.

Project description

The Idaho Department of Parks and Recreation proposes to impact approximately 46.5 linear feet of waters by discharging approximately 213.3 cubic yards of fill material in the form of bedding fill, pre-cast concrete, and rip-rap. The project will address boater safety and water quality issues related to scour by extending the existing ramp and incorporating bank armoring. Associated improvements to the existing marina are on-going and did not require a Clean Water Act section 404 permit or Clean Water Act Section 401 certification.

A copy of the application is available upon request by contacting Caroline Pierce (pierce.caroline@epa.gov), 206-553-5780.
