The plant's environmental significance includes its contribution to local air quality and greenhouse gas emissions. As a major industrial source, it is required to report emissions under the EPA's Toxics Release Inventory (TRI) program. The facility's location in a rural area of Montana may influence its impact on the surrounding environment and community.

The plant is situated in a semi-rural area of Jefferson County, Montana, near the city of Clancy. The region's air quality is generally good, but cement production can contribute to local particulate matter and other emissions. The facility's proximity to the Missouri River watershed means water discharges are regulated under the Clean Water Act to protect aquatic ecosystems. The surrounding area includes agricultural land and small communities, so the plant's operations are subject to community scrutiny regarding dust, noise, and traffic.
