WHAT THE MEASURE IS SHOWING

The trends in the number of violations recorded in the databases remained fairly stable over the last past ten years. There are significant differences by regional board ofice that may be due to differences in data entry procedures more that changes in numbers of violations.

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

National Pollutant Discharge Elimination System (NPDES)
The NPDES permit program (Section 402 of the Clean Water Act ) controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. US EPA has approved the Water Board's program to issue NPDES permits.
