WHAT THE MEASURE IS SHOWING

Although there are variations between Regional Boards, the number of violations recorded in the databases remains fairly constant over the last five years.

WHY THIS MEASURE IS IMPORTANT

Violations are detected through reviewing of self monitoring reports, inspections and complaints. The enforcement policy requires that the Water Boards ensure that all violations are documented in the appropriate Water Board data management system. According to the enforcement policy all violations will be entered within 10 days of discovery of the violation. Identification and documentation of violations is important to ensure that water quality is protected and that serious violations and those high priority violations receive an adequate enforcement response. Tracking violations and compliance rates over time is necessary to assess the effectiveness of the Water Boards enforcement policies and actions.

TECHNICAL CONSIDERATIONS

 

GLOSSARY

Construction Storm Water Program
Dischargers whose projects disturb one or more acres of soil or whose projects disturb less than one acre but are part of a larger common plan of development that in total disturbs one or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity. Construction activity subject to this permit includes clearing, grading and disturbances to the ground such as stockpiling, or excavation, but does not include regular maintenance activities performed to restore the original line, grade, or capacity of the facility. For more information, see the Construction Storm Water Program.

Industrial Storm Water Program
The Industrial General Permit is an NPDES permit that regulates discharges associated with 10 broad categories of industrial activities. The Industrial General Permit requires the implementation of Best Available Technology Economically Achievable (BAT) and Best Conventional Pollutant Control Technology (BCT) to achieve performance standards. For more information, see the Industrial Storm Water Program.

Municipal Storm Water Phase I Facilities

The Municipal Storm Water Permitting Program regulates storm water discharges from municipal separate storm sewer systems (MS4s). Storm water is runoff from rain or snow melt that runs off surfaces such as rooftops, paved streets, highways or parking lots and can carry with it pollutants such as: oil, pesticides, herbicides, sediment, trash, bacteria and metals. The runoff can then drain directly into a local stream, lake or bay. Often, the runoff drains into storm drains which eventually drain untreated into a local waterbody. For more information, see the Municipal Storm Water Program.
