On March 8, 2016, Region 10 filed a consent agreement and final order resolving violations of the Federal Air Rules for Indian Reservations (FARR) under the CAA by Cougar Den Inc. in White Swan, Washington. Respondent, which operates an air pollution source within the exterior boundaries of the Yakama Indian Reservation, failed to renew its annual FARR registration. The company agreed to pay an $898 penalty. This case was brought as part of Region 10s strategy to address noncompliance by all facilities in Region 10 that failed to comply with the FARR registration requirement during the last year.
