Concerns over local mining operations took center stage at the St. Croix County Community Development Committee meeting on June 19, 2025, as residents voiced strong opposition to a conditional use permit request from Semstone for nonmetallic mining in a residential area. The proposed expansion would add six parcels to an existing mining operation, raising alarms about potential impacts on property values, water quality, and community health.

Residents from the nearby housing development expressed fears that the mining activities would devalue their homes by at least 20%, with some estimates suggesting losses could reach millions across the community. "If the water becomes contaminated, our homes will be worthless," warned one resident, highlighting concerns about the proximity of wells to the mining site.

The committee heard from multiple homeowners who described feeling ignored and threatened by both Semstone and local officials. They criticized the perceived lack of transparency and accountability regarding the mining operations, particularly concerning noise and dust pollution. "No one wants to live by this stuff," one resident lamented, emphasizing the emotional toll on families living near the proposed site.

In response, Semstone representatives defended their operations, stating that they have been compliant with regulations since taking over the site in 2015. They assured the committee that their mining practices would not affect groundwater and that they would continue to implement dust control measures.

The committee is expected to deliberate on the permit request in the coming weeks, with residents urging officials to consider the long-term implications of mining in their community. As discussions continue, the tension between economic development and community well-being remains a critical issue for St. Croix County.
