Although no longer required, historical results are available upon request. In the past, Fort Carson’s MS4 permit required water quality sampling where major water ways entered and exited the installation. The annual report provides the EPA the status of Fort Carson’s implementation of the SWMP. As required by the permit, Fort Carson submits an annual report to EPA Region 8. The SWMP outlines the best management practices (BMPs), measurable goals and requirements Fort Carson will use to implement the six minimum control measures (MCMs).

The purpose of the SWMP is to outline measures to reduce the discharge of pollutants to the maximum extent practicable, and to protect water quality. The MS4 permit requires Fort Carson to develop a comprehensive Stormwater Management Plan (SWMP). This permit addresses municipal discharges only. The permit applies to only the cantonment area and downrange, and not Pinon Cañon Maneuver Site (PCMS). It was re-issued on Januand will expire on December 31, 2020. Fort Carson's Municipal Separate Storm Sewer System (MS4) permit numbered COR042001 went into effect April 30, 2009. Municipal Separate Storm Sewer System Permit (MS4) - EPA Region 8 has regulatory authority over stormwater management and permits at Fort Carson. These permits are managed by the Stormwater Program. The Environmental Protection Agency (EPA) has issued Fort Carson three permits (described below) under the National Pollutant Discharge Elimination System (NPDES) to protect stormwater runoff quality. Anything that enters a storm sewer system is discharged untreated into the water bodies we use for swimming, fishing and providing drinking water to people that live downstream. This runoff flows into Fort Carson’s storm sewer system or directly to a pond, creek, river or wetland. Stormwater runoff can pick up feces, debris, sediment and chemical pollutants. The Fort Carson Stormwater Program is in place to help protect our surface waters from the pollution in stormwater runoff (rain or snowmelt that flows over the ground).
