On June 16, 2016, Region 10 filed a consent agreement and final order against CHS Inc. d/b/a CHS Connell Grain Toppenish to resolve a violation of the Federal Air Rules for Indian Reservations (FARR) under the CAA. Respondent, which operates an air pollution source within the exterior boundaries of the Yakama Indian Reservation, failed to file its initial FARR registration within 90 days after beginning operation. The company agreed to pay a $3,052 penalty. This case was brought as part of Region 10's strategy to address noncompliance by all facilities in Region 10 that failed to comply with the FARR registration requirement during the last year.
