WHAT THE MEASURE IS SHOWING
Almost all of the NPDES Wastewater facilities classified as Major have their reporting requirements now in the Water Boards database (CIWQS). Of the reports that were required during fiscal year 2010-11, 76% were received.
WHY THIS MEASURE IS IMPORTANT
Self Monitoring Reports (SMR) contain information required to assess compliance with permits and to measure the quality of the discharge from regulated facilities. Data reported typically include both data required by the permit and any additional data the permittee has collected consistent with permit requirements. These self monitoring reports typically provide an assessment of the conditions of the discharge and include water quality data as analyzed by a certified laboratory and other field measurements (such PH and flow). During review of the self monitoring reports regional board staff compare the values reported with the permit requirements and determine if the self monitoring report is complete and all the reported values are within the permitted limits. In 2010 the Water Boards started to use the CIWQS database to track monitoring reports due, received and reviewed both in either electronic or paper form. This card shows the progress towards tracking the required reports using CIWQS. Self Monitoring Reports are the primary tool used to assess compliance with permit requirements. Self Monitoring Reports are submitted at different frequencies and for different purposes. Most dischargers submit quarterly and annual reports. Major dischargers may also be required to submit monthly reports. All regulated facilities must submit, at a minimum, an annual report.

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 environemental interest, permits and other orders, inspections and violations and enforcement activities.
- Major Facility
- Major municipal discharger include all facilities with design flows of greater than one million gallons per day and facilities with approved industrial pretreatment programs. Major industrial facilities are determined based on specific ratings criteria developed by US EPA/State.
- National Pollutant Discharge Elimination System (NPDES)
- The NPDES permit program (Section 402 of the Clean Water Act) control 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 ermit; 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.
