WHAT THE MEASURE IS SHOWING

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 (WDR).  The US EPA 2014 Compliance Monitoring Strategy provides inspection frequency goals for NPDES regulated facilities. It is the Water Boards’ policy to ensure that facilities comply with Water Quality Control Plans, NPDES permits, and WDRs.  This policy is implemented through Regional Water Board comprehensive self-monitoring and compliance inspection programs. Tracking the number of inspections by FY may help to improve the Water Boards’ performance.


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.

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.

General Facility
A general 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.

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.
