Programs

Permanent Water Quality (PWQ)

CDOT's Permanent Water Quality (PWQ) program is required under CDOT's Municipal Separate Storm Sewer System Permit (MS4).

Each CDOT region is responsible for evaluating new construction and redevelopment sites in the CDOT MS4 permit area to determine if stormwater controls are required. These controls are referred to as permanent water quality control measures (PWQ CM) or permanent best management practices (BMP).

For program assistance, consult region water pollution control managers/water quality specialists (see region contacts), or contact Program Manager Rachel Hansgen at [email protected] or 303-757-9975.
