The California Water Boards' Annual Performance Report - Fiscal Year 2010-11

MEASUREMENTS  - Data Last Updated on: 

WHAT THE MEASURE IS SHOWING

The percentage and number of facilities inspected varies among the Regional Board offices.  The data show a low percentage of facilities being inspected across all regions.  Region 5 conducted almost 80% of all the inspections in this category of dischargers. Although the percentage of facilities inspected varies among the different Regional Boards, approximately 10% of the 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

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.
