STATE WATER RESOURCES CONTROL BOARD -4- <br /> ORDER <br /> 4- <br /> ORDER WQ 2014-0153-DWQ <br /> GENERAL WASTE DISCHARGE REQUIREMENTS <br /> FOR SMALL DOMESTIC WASTEWATER TREATMENT SYSTEMS <br /> dissolved solids (FDS) do not degrade biologically. Elevated concentrations of FDS in <br /> land applied effluent can change soil chemistry and degrade groundwater quality. <br /> 11 . Wastewater discharged to land in close proximity to a surface water body may impact <br /> surface water quality. Additional monitoring may be required by a Regional Water <br /> Board's Executive Officer to determine if the discharge has degraded surface water <br /> quality. The USEPA recommends Escherichia coli (E. coli) and enterococci bacteria, <br /> which exist in fecal material from humans and other warm-blooded animals, as the <br /> best indicators of health risk from water contact.2 Because both bacteria are present <br /> in domestic wastewater, there is no need to monitor separately for them in wastewater <br /> effluent. The effectiveness of disinfection procedures are similar for bacteria, therefore <br /> total coliform organisms, which is a less expensive analysis, is appropriate to <br /> determine if wastewater effluent is effectively disinfected. Total coliform monitoring is <br /> required for recycled water use consistent with title 22. <br /> 12. Use of recycled water in lieu of potable water is encouraged by the State Water Board <br /> as described below: <br /> a. The State Water Board's Strategic Plan Update 2008-2012 includes a priority to <br /> increase sustainable local water supplies available for meeting existing and future <br /> beneficial uses by 1,725,000 acre-feet per year (afy) in excess of 2002 levels by <br /> 2015. <br /> b. The State Water Board's Policy for Water Quality Control for Recycled Water <br /> states the following goals (in part): 1) Increase the use of recycled water over the <br /> 2002 level by at least 1 million afy by 2020 and by at least 2 million afy by 2030. <br /> 2) Increase the amount of water conserved in urban and industrial uses by 20 <br /> percent compared to 2007. 3) Substitute as much recycled water for potable <br /> water as possible by 2030. <br /> 13.The Recycled Water Policy calls on local water and wastewater entities together with <br /> other stakeholders who contribute salt and nutrients to a groundwater basin or sub- <br /> basin, to fund and develop Salt and Nutrient Management Plans (SNMPs) to <br /> comprehensively address all sources of salts and nutrients. The State Water Board <br /> herein reasserts the need for comprehensive salt and nutrient management planning <br /> and directs that salinity and nutrient increases should be managed in a manner <br /> consistent with the Recycled Water Policy. It is the intent of the Recycled Water Policy <br /> that every groundwater basin/sub-basin in California ultimately has a consistent Salt <br /> and Nutrient Management Plan. The appropriate way to address salt and nutrient <br /> issues is through the development of regional or subregional SNMPs. Dischargers <br /> may be directed to perform or participate in SNMP planning activities as described in <br /> the Provisions of this General Order. <br /> 2 USEPA Internet page accessed June 10, 2014 <http://water.epa.gov/type/rsl/monitoring/vms5l l.cfm>. <br /> September 23, 2014 <br />
