WHAT THE MEASURE IS SHOWING

Overall 33% of the Minor Wastewater NPDES 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. All regions, with the exception of R3 exceeded their target number of inspected facilities for FY 2010-11.

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. The Water Board’s Memorandum of Agreement with US EPA specifies that minor facilities be inspected at least once every five years. This translates to 20% of all minor facilities inspected each year.

TECHNICAL CONSIDERATIONS

GLOSSARY

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.

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.
