The Colorado Department of Transportation (CDOT) has the mission to ?develop and maintain the best possible transportation system for Colorado.? This mission includes the making of decisions which are compatible with Colorado's quality of life, environmental, and economic goals. Meeting CDOT?s mission and goals requires that the maintenance and upgrading of existing highways, as well as the construction of new highways, be integrated with Colorado's environmental goals. At the same numerous federal and state regulations have been issued regarding governing land-disturbing activities and water quality. CDOT has developed several programs to comply with the National Pollutant Discharge Elimination System (NPDES) Phase I and II stormwater regulations issued by the Environmental Protection Agency (EPA), as well as other relevant legislation and regulations. This Erosion Control and Stormwater Quality Guide was developed in part to support these programs. The guide addresses the degradation of water quality associated with highway operations, and the prevention or minimization of that degradation through the implementation of planning, proper construction, and proper installation of Best Management Practices (BMPs) for erosion and sediment control and stormwater quality management. Glossary, photos, plan diagrams, references, appendix, 160 p. Reviewer?s note: long load time.
