Permit Applicant:
Central Washington Corn Processors
2908 Logston Boulevard
Richland, WA 99354
Central Washington Corn Processors (CWCP) installed additional grain processing equipment since 2015, including an increase in total production into its existing facility. As a result of this increase in total production and installation of additional equipment, air emissions have increased, mainly particulate matters (PM). This project triggers a review for the increase and installation as proposed, by Benton Clean Air Agency (BCAA) pursuant to Washington Administrative Code (WAC) 173-400-110. As such, an Order of Approval from the BCAA is required. The final Order will contain conditions under which the facility must operate to be in compliance with the local, state, and federal clean air regulations.
The lead agency for this proposal has determined that it does not have a probable significant adverse impact on the environment. An environmental impact statement (EIS) is not required under RCW 43.21C.030(2)(c). This decision was made after review of a completed environmental checklist and other information on file with the lead agency. This information is available to the public on request. This DNS is issued under 197-11-340(2); the lead agency will not act on this proposal for 15 days from August 21, 2026. Comments must be submitted by September 7, 2026.
