Stormwater Quality Program Components

Stormwater Quality Program Components

The Stormwater Quality Program monitors impacts due to urban runoff and tracks ambient conditions in Boulder Creek.

Water Quality Monitoring

Poor water quality, sediment contamination and destruction of fish and wildlife habitats can lead to the decline and degradation of valuable natural resources. The Stormwater Quality Program monitors impacts due to urban runoff and tracks ambient conditions in Boulder Creek.

To better understand impacts to Boulder's surface water, water quality is examined to discover how the water resources are changing over time, and to help identify and mitigate potential sources of pollution.

Regulatory Compliance

The Stormwater Quality Program assures compliance with all state and federal water quality regulations related to stormwater. The City of Boulder's municipal separate storm sewer system operates with a permit from the Colorado Department of Public Health and Environment.

The permit sets requirements related to six minimum control measures:

  • public education and outreach;
  • public participation;
  • illicit discharge detection and elimination;
  • construction site runoff control;
  • post-construction runoff control; and
  • pollution prevention and good housekeeping.

In addition to stormwater regulations for municipalities, federal regulations require certain industrial facilities to obtain a stormwater discharge permit. City-owned facilities such as the Wastewater Treatment Facility and the Boulder Municipal Airport are included in these current Industrial Pretreatment regulations. Stormwater discharges associated with construction activities are also required to obtain a permit.

Source Control

The Stormwater Quality Program seeks to identify and reduce illicit discharges to the stormwater system.

Source Control activities include:

  • monitoring dry weather flows to the storm sewer system,
  • tracking hazardous materials spills,
  • regulating ground water discharges, and
  • participating in Boulder County's Household Hazardous Waste Program.
