The Environmental Impact Statement (EIS) for Larson Quarry in Grey Cloud Township is still in process, affected by the federal government shutdown. The Larson Quarry EIS comes as Amrize Midwest Inc. seeks to expand the present Larson Quarry dating to 1957 to an adjacent 148-acre property it owns on the east side of County Road 75 in Grey Cloud Township.
No change in quarry operations or production levels is being proposed for the 68-year old limestone quarry, expansion as proposed extending the life of the mine by 20-25 years.
The Larson Quarry EIS is being overseen by Washington County, an earlier scoping decision document outlining EIS objectives published in June to the county website.
Washington County Planning Director Lyssa Leitner sharing the following EIS update when contacted.
“We do not have a date on when the Larson Quarry EIS will be available for review, she said. “Coordination needs to occur with the National Park Service and multiple state agencies before the EIS is drafted. The federal shutdown delayed our coordination with the Park Service.”
Pending consolation with the relevant agencies, a Draft EIS for the Larson Quarry expansion could be ready by Spring 2026.
