Colorado Water Quality Control Division The Colorado Water Quality Control Division is responsible for issuance of Water Quality Certification (401 certification) as well as administration of the Colorado Pollutant Discharge System Permits (CPDS). The Corps requires 401 certification from the state for 404 permits for the discharge of dredged or filled material. As 404 permits would be required on all alternatives, section 401 permits will also be required. If a section 401 certification is denied, then a 404 permit cannot be issued. In a 401 certification, the State determines whether there is reasonable assurance that the proposed project will not violate water quality standards or effluent limitations. It also contains conditions the State deems desirable or necessary for inclusion in the federal permitting license. The Water Quality Control Commission regulations defining the scope of 401 certification were adopted on November 6, 1985, and were revised on December 30,1994. CPDS Permits are required for point-source construction related discharges and point-source discharges from wastewater treatment plants and other facilities. CPDS permits may be required for all construction alternatives. Permits are obtained by applying to the Water Quality Control Division through a Colorado Discharge Permit System application for construction, dewatering and wastewater discharge. This is required for construction activities and typically would be applied for during the final design or at the beginning of construction for a project. Permits for stormwater discharge associated with construction activity are also required. This permit requires the preparation of a Stormwater Management Plan. The permit application is required at least ten days prior to the anticipated date of discharge. This permit is typically applied for during final design or at the beginning of construction. Colorado Air Pollution Control Division The Colorado Air Pollution Control Division issues permits for Air Pollutant Emissions and Open-Burning. The Air Pollutant Emission Permit is required to control construction related emissions resulting from service disturbance and construction activities. Permit application requires a description of the type of construction activities which are projected as well as air pollution control activities such as watering, chemical stabilization, compaction of piles, enclosures or revegetation. The Open-Burning Permit is required if burning of materials would occur. The Division encourages hauling and land-filling of construction materials rather than burning. Coordination with the County is required on the issuance of any Burning Permits. ($ 10
