WHAT THE MEASURE IS SHOWING
The data show a downward trend in the number of inspections conducted since Fiscal year 2000-2001. This downward trend is not equal in every region and regions such R5 and R4 had been able to maintain the number of inspections conducted. For compliance purposes, some facilities are inspected more than once a year, which 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 determining and documenting compliance with National Pollutant Discharge Elimination System (NPDES) permits and waste discharge requirements. Because of their size, major facilities represent a higher threat to water quality and receive a higher degree of compliance assurance activities. Recent revisions to the Water Board’s Memorandum of Agreement with US EPA specifies that major facilities be inspected at least once every two years or annually if violations are detected.
TECHNICAL CONSIDERATIONS
GLOSSARY
- Major Facility
- Major municipal dischargers 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 ) 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.
