Central Valley Regional Water Quality Control Board (Central Valley Water
Board) staff is developing the National Pollutant Discharge Elimination System
(NPDES) permit renewal for the Sacramento Regional County Sanitation
District's (SRCSD) Regional Wastewater Treatment Plant discharge to the
Sacramento River. The proposed permit renewal is scheduled to be considered
by the Central Valley Water Board for adoption in 2010. The existing NPDES
permit (Waste Discharge Requirements Order No. 5-00-188) regulates the
discharge of up to 181 million gallons per day (mgd) of secondary treated
municipal wastewater to the Sacramento River, within the Sacramento -San
Joaquin Delta (Delta). For the proposed permit renewal, the SRCSD is
requesting an increase of its permitted average dry weather discharge flow from
181 mgd to 218 mgd for this regional facility to accommodate future growth in .the
greater Sacramento area.
There are many significant interrelated issues that must be addressed in the
renewed NPDES permit. Through the attached Issue Paper, Central Valley
Water Board staff has identified aquatic and wildlife issues and is seeking public
comments and additional information regarding the NPDES permitting
requirements necessary to protect the following beneficial uses for the Delta:
warm and cold freshwater habitat (WARM and COLD), wildlife habitat (WILD),
migration of aquatic organisms (MIGR), and spawning, reproduction, and/or early
development (SPWN). Through this effort, Central Valley Water Board staff is
soliciting input from stakeholders to assist in identifying deficiencies in protection
of the beneficial uses of the Sacramento River (and the Delta), and potential
conflicts with other agency's programs, as it pertains to the subject discharge.
