The California Water Boards' Annual Performance Report - Fiscal Year 2012-13

MEASUREMENTS  - Data Last Updated on: 

WHAT THE MEASURE IS SHOWING

Although the percentage of facilities inspected varies among the different Regional Water Boards, the statewide percentage of facilities inspected is relatively high. Overall, 27% (compared to 26% in FY 11-12) of the large municipal facilities were inspected. Some facilities are inspected more than once a year; that is why the total number of inspections is greater than the total number of facilities inspected.

WHY THIS MEASURE IS IMPORTANT

It is the policy of the State Water Resources Control Board (SWRCB) to ensure compliance with Water Quality Control Plans, NPDES permits, and Waste Discharge Requirements through Regional Board implementation of a comprehensive self-monitoring and compliance inspection program. Inspections are a primary tool used in the WDR program to assess compliance with requirements. Inspection frequencies for WDR facilities are based on threats to water quality. In addition, the Regional Boards assess compliance by reviewing self-monitoring reports submitted by the discharger and responding to complaints. Validation of conditions described by self-monitoring data must be done through periodic inspection, and inspection is the only means to evaluate system maintenance and to observe unreported activities. Inspections are performed by priority, with high-risk sites and registered complaints receiving more attention. Large Municipal facilities are typically considered a greater threat to water quality.

GLOSSARY

Large Municipal Facilities

Facilities discharging municipal waste serving a population equivalent to 1,000 people and with a design flow of greater than 100,000 gallons a day. This group only includes those facilities regulated with individual Waste Discharge Requirements (WDR).

Municipal Sources

Facilities that treat sewage or a mixture of predominantly sewage and other waste from districts, municipalities, communities, hospitals, schools, and publicly or privately owned systems (excluding individual surface leaching systems disposing of less than 1,000 gallons per day).

Waste Discharge Requirements Program

The Waste Discharge Requirements (WDR) Program regulates all point source discharges of waste to land that do not require full containment (which falls under the Land Discharge Program), or are not subject to the NPDES Program.

Inspection (Compliance and Non Compliance)

The Regional Board or State Board may inspect the facilities of any discharger at any time pursuant to Water Code, Section 13267. Compliance activities include all activities necessary to determine if discharges are in compliance with waste discharge requirements, NPDES permits, and related enforcement orders. Compliance inspections are classified as either Level A or Level B, with Level A being more thorough.
