Pollution Prevention & Good Housekeeping (PPGH)

Program Description

This program is part of CDOT’s individual Municipal Separate Storm Sewer System Permit (MS4 Permit), COS000005. CDOT protects water quality by implementing Facility Runoff Control Plans (FRCPs) to identify and control pollutants from their facilities and operations. FRCPs ensure that appropriate Control Measures (CMs) are implemented and maintained to prevent stormwater runoff from becoming contaminated, and potentially discharging from a CDOT facility. Sections of the FRCP describe the proper CMs for where potential pollutants might migrate if they come in contact with stormwater. For example, CDOT staff will sweep the area in front of the covered solid deicer storage area, to prevent potential pollutants from coming in contact with stormwater. Facility Runoff Control Plans specific for each site require routine and annual inspections.

While working on the roadways, CDOT Maintenance Staff also maintain CDOT's storm drain systems and specific Permanent Water Quality Control Measures to maintain good stormwater quality; by using proper CMs. For example, they remove potential pollutants, including trash, sediment, and debris preventing them from entering waterways.

CDOT maintenance staff also watch for illicit discharges at CDOT maintenance facilities and while maintaining CDOT roadways. For more information go to the Illicit Discharge Program webpage.

The photos below demonstrate CDOT storing equipment with hydraulic hoses connected in a closed circuit and wrapped with absorbent pads then plastic to ensure potential pollutants do not come in contact with stormwater.
