The Division has identified 2018 nitrate visibility impacts at Wheeler Peak (WHPE) Wilderness Area that trigger interstate consultation with New Mexico. Also, Colorado nitrate impacts are of concern at two other nearby New Mexico Class I areas (BAND & SAPE), Canyonlands National Park (CANY) in Utah, and Wichita Mountains NWR Wilderness in Oklahoma. The "concern" visibility impacts are at or slightly above the arbitrary threshold criteria established by the Division. The Western Regional Air Partnership (WRAP) Implementation Working Group (IWG) has not formally established threshold criteria on interstate Class I area impacts but an informal threshold of 10% has been suggested among member states. If the Division were to utilize the informal threshold criteria of the WRAP Colorado would have only one 2018 visibility impact on two nearby Class I areas exceeding the 10% threshold., Online resource; title from PDF cover (viewed June 2017)

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., CDM, HE, Risk Sciences ; on behalf of Colorado Department of Public Health and Environment, Colorado Water Resources & Power Development Authority., "December 2011.", Online resource; title from PDF cover (viewed June 2016)
