Public Notice: Proposed Synthetic Minor Source Air Permit for Granite Construction Company in Okanogan, Washington

Publish Date: 12/27/2018


The EPA is seeking public comment on a draft Clean Air Act synthetic minor source air permit to establish emission limits that allow Granite Construction Company's hot mix asphalt plant in Okanogan, Washington to be treated as a minor source of air pollution and thereby avoid permitting requirements that apply to major sources of air pollution under the Title V operating permitting program.

By limiting annual asphalt production to 300,000 tons, the synthetic minor source permit will assure that emissions of regulated air pollutants will reamin below major source thresholds.
