The Water Quality Control Division administers a stormwater program, designed to <br />control stormwater runoff from certain categories of industrial activity, including mining. Your <br />facility falls under one of these categories. Our records indicate that you have not applied for or <br />obtained a stormwater permit for the above-referenced mining operation. <br />Background <br />In 1987, the L3S Congress amended the Clean Water Act to expressly include stormwater discharges <br />fmm mining sites (and other industries) as requiting Clean Water Act controls. In 1990, EPA issued <br />regulations that trquire specific mining activities to obtain permits in order to discharge stormwater <br />from their facilities. <br />The stormwater regulations apply to active and inactive trines, if runoff contacts overburden, raw <br />material, intermediate or furished product, or waste products, and leaves the site. <br />'The Water Quality Control Division of the Colorado Department of Pubtic Health and Environment <br />has direction and authority to administer this program in Colorado. The Division has issued a general <br />permit for Sand and Gravel Mining and Processing (and other nonmetallic minerals except fuel). <br />Annlication Requirement <br />An application form for the General Permit has been enclosed. Please complete an application for the <br />site and submit it to our office by August 3, 1995.
