Title: Teacher resources for introducing urban stormwater quality concepts to the classroom : including example lesson plans meeting Colorado standards for science, geography and civics
Abstract: Our drinking water supplies, fishing and recreational waters are fouled by uncontrolled pollution when rainwater and snowmelt wash over city streets, parking lots, and suburban lawns and pick up toxic chemicals, disease-causing organisms (from pet waste), and dirt and trash. This problem is called urban stormwater pollution. Recent studies have found that urban stormwater rivals and in some cases exceeds sewage plants and large factories as a source of damaging pollutants. Two hundred years of unregulated, unmanaged urban stormwater have contributed to many severe public health problems and expensive natural resource losses in the United States.

Title: Public opinions on water quality issues
Abstract: This report contains findings for a statewide survey of Colorado residents on the topic of water quality issues. This report includes both key findings and detailed findings of this survey. In addition to overall statewide findings, additional findings are analyzed by geographic regions (i.e. Front range, eastern plains, San Luis Valley, etc.), age and education level demographics, and attitudes about "willingness to pay."

Title: Total maximum daily load assessment Silver Creek Dolores County, Colorado
Abstract: Total Maximum Daily Load (TMDL) is used to determine the maximum amount of a pollutant that a water body may receive and still maintain water quality standards. The mainstem of Silver Creek from a point immediately below the Town of Ricos water supply diversion to the confluence with the Dolores River is included in the 2006 303(d) list for exceeding the Aquatic Life use standards for zinc and cadmium.

Title: Total maximum daily load assessment Arkansas River/Lake Creek/Chalk Creek/Evans Gulch Lake/Chaffee County, Colorado
Abstract: The Arkansas River drainage basin lies south and west of the town of Leadville. The listed segments on this 303(d) listed portion of the upper Arkansas account for 163 miles of the 1,450 mile length of river. Many tributaries flow into the Arkansas River including Lake Creek, Chalk Creek, and Evans Gulch, which are also listed on the 1998 303(d) list for elevated metal concentrations.

Title: Total maximum daily load for mercury in Sanchez Reservoir, Colorado
Abstract: The Colorado Department of Public Health and the Environment (CDPHE) has identified Sanchez Reservoir in Costilla County as not supporting its designated uses due to the presence of elevated fish tissue concentrations of mercury that have resulted in Fish Consumption Advisories. Mercury concentrations at the levels observed present a significant health risk to persons who consume listed fish from the reservoir. Because Sanchez Reservoir does not support its designated uses, a Total Maximum Daily Load (TMDL) is required for mercury loading to the lake.

Title: Colorado discharge permit system (CDPS) general permit COR900000 for stormwater discharges associated with non-extractive industrial activity : developing your stormwater management plan (SWMP) : technical assistance for industrial facility operators
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.

Title: Report, cost/benefit study of the impacts of potential nutrient controls for Colorado point source discharges
Abstract: The Colorado Department of Health and Environment (CDPHE) Water Quality Control Division is developing an approach to manage nutrients in Colorado waters. The primary driver for this effort has been an Environmental Protection Agency (EPA) directive to reduce nutrients in waters under jurisdiction of the federal Clean Water Act (CWA). The Division's proposal to control the discharge of nutrients relies largely on a technology-based control regulation that would establish effluent limits for both total phosphorus (TP) and total inorganic nitrogen (TIN) for many domestic and some nondomestic wastewater treatment facilities that become subject to the control regulation will have to invest in capital improvements and ongoing operation and maintenance (O&M) costs.

Title: Total maximum daily load for mercury in McPhee & Narraguinnep Reservoirs, Colorado. Phase I
Abstract: The Colorado Department of Public Health and the Environment (CDPHE) has identified McPhee & Narraguinnep Reservoirs as not supporting their designated uses due to the presence of elevated fish tissue concentrations of mercury that have resulted in Fish Consumption Advisories. Mercury concentrations at the levels observed present a significant health risk to persons who consume listed fish from the reservoirs. Because McPhee & Narraguinnep Reservoirs do not support their designated uses, a Total Maximum Daily Load (TMDL) is required for mercury loading to the reservoirs. The purpose of this TMDL is to provide an estimate of pollutant loading reductions needed to restore the classified uses of McPhee and Narraguinnep reservoirs. The U.S. Environmental Protection Agency (EPA), Region 8, is supporting CDPHE in the development of this TMDL.
