Summary

On January 29, 2026, EPA received a request from the Stillaguamish Tribe of Indians for a water quality certification for the Angel of the Winds Casino and Resort Anderson Employee Parking Lot Project [U.S. Army Corps of Engineers Seattle District project number NWS-2025-925].

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, then EPA is the certifying authority.

In this case, the proposed project is within the Stillaguamish Reservation. Therefore, EPA is the certifying authority for the proposed project.

According to the application, the Stillaguamish Tribe of Indians proposes to impact wetlands in order to construct a parking lot. The project is located on Tribal lands in Snohomish County near Arlington, Washington (latitude 48.2138, longitude -122.1816).

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

Project description

The Stillaguamish Tribe of Indians proposes to impact approximately 0.476 acres of wetlands by discharging approximately 1,000 cubic yards of fill material. The project will result in the creation of a new 450 vehicle employee parking lot for the adjacent Angel of the Winds Casino and Resort, and will include bioretention facilities to provide treatment for post-construction stormwater generated from the 3.7 acres of new impervious surface area equivalent to the 100-year storm event. Mitigation will be provided through the use of 0.476 credits at the Tribe’s existing advance permittee-responsible mitigation site.

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