WHY THIS MEASURE IS IMPORTANT

TECHNICAL CONSIDERATIONS

GLOSSARY

Self Monitoring Report
The form used to report self-monitoring results by regulated facilities. Self Monitoring: Sampling and analyses performed by a facility to determine compliance with a permit or other regulatory requirements.

CIWQS
The California Integrated Water Quality System (CIWQS) is a web-based relational database for core regulatory data. Using this system, both staff and the public can access data related to places of environmental interest, permits and other orders, inspections and violations and enforcement activities.

Minor Facility
A minor facility is a discharge with a design flow of less than one million gallons per day (MGD) that has not been determined to have an actual or potential adverse environmental impact classifying the discharge as major.

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.

NPDES Permit
The Clean Water Act prohibits anybody from discharging "pollutants" through a "point source" into a "water of the United States" unless they have an NPDES permit. The permit contains limits on what can be discharged, monitoring and reporting requirements, and other provisions to protect water quality and public health. In essence, the permit translates general requirements of the Clean Water Act into specific provisions tailored to the operations of each person discharging pollutants.
