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.
The Safe Drinking Water Program of the Water Quality Control Division at the Colorado Department of Public Health and Environment fully implements a Capacity Development Program that aligns with the requirements of the Safe Drinking Water Act (SDWA). As required by the 1996 Amendments, the Safe Drinking Water Program has prepared this document to describe Colorado's capacity development strategy and to establish the nine strategic goals used to support and guide ongoing strategic planning efforts.
The Colorado Department of Public Health and Environment (CDPHE) has completed a source water assessment for Broomfield City and County as required by the 1996 Safe Drinking Water Act amendments and in accordance with Colorado's Source Water Assessment and Protection (SWAP) program. The purpose of this assessment is to analyze the potential susceptibility of each public drinking water source to contamination, and to supply pertinent information so that decision-makers voluntarily can develop and implement appropriate preventive measures to protect these water sources. The Safe Drinking Water Act requires that the public water system and its consumers be informed of the assessment results.
The Basic Standards and Methodologies for Surface Waters (Regulation No. 31, 5 CCR 1002-31) contains antidegradation provisions which provide three separate levels of antidegradation protection (see section 31.8). This document is intended to provide guidance to Water Quality Control Division staff and to the public regarding the implementation of the antidegradation significance tests found in Regulation No. 31. This guidance is designed as a framework to provide a documented methodology and to ensure antidegradation reviews are conducted in a consistent manner. Unique situations will be assessed on a case-by-case basis, using site-specific data and methodology.
The Colorado Department of Public Health and Environment (CDPHE) has completed a source water assessment for Fremont County as required by the 1996 Safe Drinking Water Act amendments and in accordance with Colorado's Source Water Assessment and Protection (SWAP) program. The purpose of this assessment is to analyze the potential susceptibility of each public drinking water source to contamination, and to supply pertinent information so that decision-makers voluntarily can develop and implement appropriate preventive measures to protect these water sources. The Safe Drinking Water Act requires that the public water system and its consumers be informed of the assessment results.
The Colorado Department of Public Health and Environment (CDPHE) has completed a source water assessment for Grand County as required by the 1996 Safe Drinking Water Act amendments and in accordance with Colorado's Source Water Assessment and Protection (SWAP) program. The purpose of this assessment is to analyze the potential susceptibility of each public drinking water source to contamination, and to supply pertinent information so that decision-makers voluntarily can develop and implement appropriate preventive measures to protect these water sources. The Safe Drinking Water Act requires that the public water system and its consumers be informed of the assessment results.
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.
The purpose of this document is to describe and standardize the process by which fish consumption advisories (FCAs) are developed and publicly disseminated in Colorado. This document identifies the roles and responsibilities of the state agencies involved in the process, and describes the steps involved in implementing this policy.
The Colorado Department of Public Health and Environment (CDPHE) has completed a source water assessment for Las Animas County as required by the 1996 Safe Drinking Water Act amendments and in accordance with Colorado's Source Water Assessment and Protection (SWAP) program. The purpose of this assessment is to analyze the potential susceptibility of each public drinking water source to contamination, and to supply pertinent information so that decision-makers voluntarily can develop and implement appropriate preventive measures to protect these water sources. The Safe Drinking Water Act requires that the public water system and its consumers be informed of the assessment results.
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.
The sample collection and analytical results required by the Colorado Discharge The purpose of this guidance document is to provide instruction and assistance to the regulated community on how to properly prepare, complete, and submit discharge monitoring reports (“DMRs”). The procedures and/or methods described in this document are provided for information only.
The Colorado Department of Public Health and Environment (CDPHE) has completed a source water assessment for Jefferson County as required by the 1996 Safe Drinking Water Act amendments and in accordance with Colorado's Source Water Assessment and Protection (SWAP) program. The purpose of this assessment is to analyze the potential susceptibility of each public drinking water source to contamination, and to supply pertinent information so that decision-makers voluntarily can develop and implement appropriate preventive measures to protect these water sources. The Safe Drinking Water Act requires that the public water system and its consumers be informed of the assessment results.
