Cemstone makes every effort to minimize and eliminate noise from our facilities. This includes installing rubber screens at our aggregate facilities to dampen sound from the aggregate hitting the screens and installation of berms and noise walls at our facilities to minimize the sound leaving our sites.
Our aggregate processing facilities use closed loop settling pond systems to supply the water for washing and classifying of aggregates. These systems collect the excess water from processing and circulate it back through the pond system to be used again. The use of the closed-loop system reduces our operations’ needs for fresh water.
Finally, long-range future planning for Cemstone’s sand & gravel operations is crucial to ensure good returns on the property as well as promote stable environments with native vegetation. Cemstone has partnered with the Minnesota DNR to create wildlife habitat through the mining reclamation process in Farmington, MN. Cemstone’s site sits in the Vermillion Highlands regional recreation area, a popular recreation and public hunting complex in Dakota County. As we close out mining, the area is reclaimed to include rolling hills and water bodies to enhance the habitat for area wildlife.
