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. 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
- 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).
- Small Municipal and Domestic Waste Facilities
- Facilities discharging municipal waste serving a population equivalent to less than 1,000 people and with a design flow less than 100,000 gallons a day. Small municipal waste facilities are typically regulated under a general order and may include facilities discharging to subsurface systems such as septic tanks and leach fields or small wastewater package plants
- Industrial Sources
- Facilities that treat and/or dispose of liquid or semisolid wastes from any servicing, producing, manufacturing or processing operations of whatever nature including mining, gravel washing, geothermal operations, air conditioning, ship building and repairing, oil production, storage and disposal operations, and water well pumping.
- All other WDR facilities
- All facilities that treat and/or dispose of wastes that do not fall into one of the Municipal, Industrial and Agricultural Waste categories. It does not include Dairies or other Confined Animal facilities.
- 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.
