Title
Colorado's phase II municipal guidance : a guide to application requirements and program development for coverage under Colorado's phase II municipal stormwater discharge permit
Abstract
The federal Clean Water Act requires that stormwater discharges from certain types of facilities be authorized under stormwater discharge permits. The goal of the stormwater permits program is to reduce the amount of pollutants entering streams, lakes and rivers as a result of runoff from residential, commercial and industrial areas. The original 1990 regulation covered municipal (i.e., publicly-owned) storm sewer systems for municipalities over 100,000 population. The regulation was expanded in 1999 to include smaller municipalities as well. This expansion of the program is referred to as Phase II.

Abstract
Storm water runoff is water from rain or snowmelt that does not immediately infiltrate into the ground, and instead flows through natural or man-made conveyance or storage systems. Stormwater runoff volume is greater in areas with high proportions of impervious surfaces (e.g., paved roads, buildings, parking lots, etc.). Runoff from areas where industrial activities are conducted can contain pollutants when facility practices allow exposure of industrial materials or activities to stormwater. To regulate the amount of pollutants entering Colorado Waters, the Colorado Water Quality Control Act mandates that certain types of industrial activities that discharge stormwater to state waters must obtain coverage under a Colorado Discharge Permit System (CDPS) permit issued by the Colorado Water Quality Control Division.
