WHAT THE MEASURE IS SHOWING

The number of municipal waste facilities with a permit past the recommended review date is relatively high compared to total number of municipal wastewater facilities regulated under the program. Although 389 permits need to be reviewed,  5 permits were renewed or reissued during fiscal year 10-11. The backlog of unreviewed permits varies among the different regional boards.

WHY THIS MEASURE IS IMPORTANT

Small Municipal facilities regulated under individual Waste Discharge Requirements (WDRs) typically represent a small threat to water quality and reduced complexity but the large number of facilities represents a significant workload effort for the Water Boards. WDRs are issued for the duration of the discharge and do not contain an expiration date. Regional Boards are authorized to review WDRs periodically pursuant to Section 13263(e) of the Porter-Cologne Water Quality Control Act. The State Legislature has found that many WDRs are out of date and therefore do not reflect existing laws, regulations, and revised Water Quality Control Plans.  The Water Boards recommend that WDRs be reviewed on a frequency of five, ten or fifteen years, based on the discharger’s Threat to Water Quality (TTWQ). WDRs that have not been reviewed/updated are considered to be backlogged. This measure describes the workload associated with existing requirements.

TECHNICAL CONSIDERATIONS

GLOSSARY

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).

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 of lower than 100,000 gallons a day. Small municipal waste facilities are typically regulated under a general order and may include facilities discharging to subsurface system such as septic tanks and leach fields and the treatment systems may be small package plants.

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.
