Denton County will formally request that the Texas Commission on Environmental Quality deny an air quality standard permit requested by Mutual First LLC after county commissioners passed a resolution Jan. 7.The permit, if approved, would authorize the construction of a permanent concrete crusher at 5120 E. University Drive, Denton. Commissioners unanimously voted to oppose the permit, citing concern that the proposed facility would be too close to Lewisville Lake, a source of drinking water for multiple area cities, including Lewisville, Flower Mound and Highland Village.The resolution states that concrete crushing is known to produce silica dust and particulate matter that can cause serious health problems for people exposed to it for extended periods of time.“This location is not a suitable site because of its proximity to drinking water sources,” the resolution stated. “Specifically, the proposed site of the facility is on the banks of Lewisville Lake, the drinking water supply for millions of North Texans.”Commissioner Hugh Coleman said he believes that Mutual First LLC may have good intentions for the facility, but he believes they have chosen an inappropriate location.“The Commissioners Court’s opposition to the permit demonstrates our collective concerns about the health and welfare of all Denton County residents,” Denton County Judge Andy Eads said in a statement.
