CPM Development Corp. plans to expand sand and gravel mining operations in the city of Airway Heights, according to a land-use permit application on file with the city.

Representatives of CPM couldn’t be reached immediately for comment.

Environmental documents show the company is seeking rezoning on 20 acres of land, to heavy industrial from light industrial, as well as a conditional-use permit to allow mining.

The site is located west of the Kalispel Tribe of Indians’ 243-acre Qlispé Raceway Park, formerly Spokane County Raceway, and east of the 183-acre Spokane County Off-Road Vehicle Park. CPM operates an existing mining operation nearby, at 110 N. Hayford. 

The company wants to extract 900,000 tons of material over a five-year period, according to application information. Depending on demand, CPM could begin mining in one to three years and continue for five years, as market conditions allow, environmental documents show.

CPM purchased the parcel in December for $450,000 from Spokane-based Washington Motorsports LP, Washington state tax documents show.

Environmental documents show the parcel is generally flat.

CPM is a Spokane Valley-based holding company that operates subsidiaries, including Central Pre-Mix Concrete Co., and Inland Asphalt Co., which produce aggregates, asphalt, and ready-mix concrete.

CPM’s parent company is Atlanta-based Americas Materials. 

CPM had 489 full-time employees as of April 2022, according to the Journal’s most recently published list of Spokane-area manufacturers.
