CDOT's Water Quality Program's mission is to:

• Ensure the quality of stormwater runoff is protected while Colorado's roadways are constructed, operated,and maintained;
• Promote innovative 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.

CDOT has a permit from the Colorado Department of Public Health and Environment (CDPHE) to discharge stormwater from the roadway storm drain system. The permit states that only stormwater (and a few other allowable discharges, like landscape irrigation overflow) can be discharged from CDOT's storm drain system and into Colorado waterways. Pollutants, such as dirt, fertilizers, pesticides, oil and grease, and antifreeze must be prevented as much as practicable from entering CDOT's storm drain system.

As part of the permit, CDOT has several different programs in place to ensure the amount of pollutants entering the storm drain system is reduced:

• Construction sites program;

• New development and redevelopment program;

• Illicit discharges program;

• Industrial facilities program;

• Public education and involvement program;

• Pollution prevention and good housekeeping program; and

• Wet weather monitoring program.

In addition, CDOT must obtain permit coverage from CDPHE for construction sites that disturb one acre or more. CDOT's Water Quality Program and CDPHE's stormwater construction permit work together to control polluted stormwater runoff from entering Colorado's waterways.
