Stone Quarrying, Crushing and Screening Facilities General Air Quality Permit Request for Coverage: Granite Construction Inc. - Omak Facility

Below are documents related to EPA's approval of Granite Construction, Inc. Request for Coverage under the General Air Quality Permit for New or Modified Minor Source Stone Quarrying, Crushing and Screening Facilities in Indian Country (SQCS General Permit) for the Omak Facility on the Colville Indian Reservation, near Omak, Washington.

The EPA approved Granite Construction’s request for coverage on September 22, 2016.

On March 5, 2019, EPA issued guidance regarding the applicability of the SQCS General Permit in light of EPA's issuance of a synthetic minor source permit to Granite Construction for its hot mix asphalt (HMA) plant. The synthetic minor source permit for the HMA plant replaces EPA's HMA General Permit. Replacing the HMA General Permit with the synthetic minor source permit for the HMA plant has no effect on the applicability of the SQCS General Permit.
