1437 regulations defining the scope of 40 I 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. Colorado Division of Water Resources The Colorado Division of Water Resources (CDWR) must approve plans and specifications for any jurisdictional dam which is more than IO feet high, has a capacity more than 100 acre-feet, or has a surface area of more than 20 acres. Since all of the enlargement alternatives have reservoirs which exceed these criteria, the CDWR will be a participant in a reservoir plan approval. This approval is based on a technical review of plans and specifications for dams which are prepared by a registered professional engineer in Colorado, in accordance with the requirements of the State Engineer's Office. Supporting data, such as geotechnical reports, hydrological reports, design assumptions and criteria, and cost estimates are also required. Water rights applications may be required to store water in any of the proposed reservoirs. ~ 8 Permitting and Regulatory Issues .... .....~, _.
