DEQ seeks comments for Draft Environmental Assessment of proposed Montana Limestone Resources Mine

HELENA – The Montana Department of Environmental Quality seeks public comment on a Draft Environmental Assessment for a proposed limestone quarry near Drummond.


Montana Limestone Resources, LLC, is seeking an operating permit to extract and process limestone at a 546-acre site on property owned by Washington Limestone Resources. The property is approximately 2.5 miles west of Drummond in Granite County. Approximately 7,000 tons of limestone per week would be extracted from the open pit mine. The material would be processed on site into lime for water treatment and mill workings at the Montana Resources copper and molybdenum mine in Butte.


The Draft Environmental Assessment evaluates the potential environmental impacts resulting from the proposed project, pursuant to the requirements of the Montana Environmental Policy Act. Public scoping was conducted between May 20 and June 19, 2019. The public identified noise, air quality, ground water, and aesthetics as the primary concerns. The Draft Environmental Assessment analyzes two alternatives—the Proposed Action and a No Action alternative.
