Industries Covered <br />Under this general permit, the following types of facilities may be granted authorization to discharge stormwater runoff <br />into waters of the state of Colorado: <br />Facilities engaged in the mining and processing of sand and gravel (including rock or stone used as aggregate, and <br />recycling of concrete and asphalt), and mining and quarrying of other nonmetallic minerals (except fuels or graphite), <br />as described by the Standard Industrial Classification (SIC) Code 14, and asphalt and concrete batch plants located at <br />these facilities. <br />a. Stormwater: This permit is intended to cover stormwater runoff from those portions of a nonmetallic minerals <br />production operation that are not subject to effluent limitations under 40 CFR 436. <br />For the purposes of this permit, stormwater discharges authorized under this permit include stormwater runoff <br />from: <br />1) Roads and railroad lines; <br />2) Pond outslopes; <br />3) Inactive loadouts; <br />4) stockpiles of overburden, raw material, intermediate products, byproducts, finished products or waste <br />products; <br />5) Sites used for storage and maintenance of material handling equipment; and <br />6) Other sources not covered under the list of process waters in Part I.A. Lb, below. <br />b. Stormwater vs. Process water: When stormwater mixes with process water, any discharge of the resulting <br />mixed water to state waters must be authorized by a separate CDPS discharge permit. For purposes of this <br />permit, discharge of process-generated wastewaters are not authorized by this permit, including: <br />1) Product wash waters; <br />2) Maintenance/equipment wash waters; <br />3) Transport waters; <br />4) Scrubber waters (crushers or classifiers); <br />5) Mine dewatering (groundwater and/or runoff); <br />6) Other process water as determined by the permit issuing authority; <br />7) Stormwater runoff from mine or processing areas; and <br />8) Stormwater runoff, which mixes with process generated wastewater before sampling. <br />2. Dredge and Fill Operations <br />This permit does not constitute authorization under 33 U.S.C. 1344 (Section 404 of the Clean Water Act) of any stream <br />dredging or filling operations. <br />3.
