The California Water Boards' Annual Performance Report - Fiscal Year 2011-12

MEASUREMENTS  - Data Last Updated on: 

WHAT THE MEASURE IS SHOWING

The number of facilities with a permit past the review date is relatively high compared to the total number of industrial facilities regulated under the program. Only 53% of the permits for industrial facilities have been reviewed/updated in accordance within the recommended frequency.  Although 363 (compared to 364 in FY 10-11, 485 in FY 09-10 and  374 in FY 08-09) permits need to be renewed, only 14 permits were reissued or reviewed during fiscal year 11-12. The backlog of expired permits varies among the different regional boards. Industrial facilities enrolled under a general permit are not considered past expiration date.

WHY THIS MEASURE IS IMPORTANT

Waste Discharge Requirements (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 The State Legislature has found that many WDRs are out of date and therefore do not reflect existing laws, regulations, and revised Water Quality Control Plans.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 permits.

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.

Review/Update Actions

The Waste Discharge Requirements WDRs are to be reviewed according to a schedule based upon their Threat to Water Quality (TTWQ) Category as follows: TTWQ 1= Every 5 years, TTWQ 2= Every 10 years and TTWQ 3= Every 15 years. TTWQ 1 has the highest priority. There are three possible actions which may result from the WDR review/update process: rescission, continuance, or revision. A revision requires the issuance of a new WDR with a new adoption date. No formal Regional Board action is required to continue WDRs without change. A memorandum signed by the Regional Board Executive Officer (EO), documenting that the review concluded that the existing WDR is appropriate and that no changes are necessary at this time, is placed in the WDR file.
