Water Quality

Welcome to the Water Quality Program of the Colorado Department of Transportation (CDOT).

Protecting water quality is a priority for everyone at CDOT, from headquarters to the five regional offices. The mission of CDOT's Water Quality Program is to:

  • Ensure the quality of stormwater runoff is protected while Colorado's roadways are constructed, operated, and maintained;
  • Promote innovative control measures (best management practices);
  • Provide effective water quality education to CDOT staff; and 
  • Facilitate cooperation between CDOT, watershed groups, other Water Quality Program managers, businesses, and the public.

Additionally, CDOT is required to comply with the requirement of the CDOT Municipal Separate Storm Sewer System (MS4) permit. CDOT's MS4 permit authorizes discharges from the municipal storm sewer system within the permit area. The permit requires CDOT to use control measures to prevent or reduce the discharge of pollutants to state waters. The permit does this by requiring CDOT to comply with seven MS4 programs.

About the Water Quality Program

The Headquarters Water Quality Program is administered by the Hydrologic and Ecological Design Resources Section (HRED) in the Environmental Protection Branch (EPB) at the Division of Transportation Development (DTD).

Each of the five regions also has water quality and environmental staff members (responsible for implementing the MS4 Program).

PDD's available upon request.


Requesting Additional Information or Submitting a Complaint

If you have questions, would like additional information, or have a complaint associated with CDOT’s actions to meet the requirements of this permit please send call Tripp Minges. He may also be contacted regarding failures to implement or inadequate control measures.

The 7 MS4 Programs

Construction Sites Program

The MS4 permit requires CDOT to implement a program to reduce or prevent the discharge of pollutants to the MS4 from covered construction activities. The requirements include assuring adequate design, implementation, and maintenance of Control Measures at CDOTs construction sites.

CDOT must require control measures be selected, designed, installed and implemented, and maintained to provide control for all potential pollutant sources associated with the covered construction site to prevent pollution or degradation of state waters. Additionally CDOT must require Stormwater Management Plans (SWMPs), provide inspections of its construction sites, and have enforcement procedures to enforce the requirements of the permit.

Program Manager: The nature of the Construction Program is varied. Therefore, there are managers for specific elements plus region mentors.

Permanent Water Quality (PWQ) Program

The NDRD Program requires CDOT to implement a program to reduce the discharge of pollutants to the MS4. To achieve this CDOT must require control measures to be installed on Priority Development and Cherry Creek Development projects. CDOT must contribute $6,500,000 annually to a pool each fiscal year to be used on to plan, design, and construct PWQ control measures that treat CDOT MS4 area.

For more information about the PWQ Program please view the PWQ website (includes information on CDOT only Call for PWQ Projects) and for Local Agency specific information on Call for Projects please see the more information the PWQ Local Agency Call for Projects website.

Illicit Discharges Program

The Illicit Discharge Detection and Elimination (IDDE) Program requires CDOT implement a program to detect and remove (or advise the discharger to the MS4 to obtain a separate CDPS permit for) illicit discharges and improperly disposed materials into the MS4.

Information on tracing, removing, and enforcement of Illicit Discharges can be found in the 2009 Illicit Discharge Program Manual.
