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).
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 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.
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 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.
