STATE WATER RESOURCES CONTROL BOARD -5- <br /> ORDER <br /> 5- <br /> ORDER WQ 2014-0153-DWQ <br /> GENERAL WASTE DISCHARGE REQUIREMENTS <br /> FOR SMALL DOMESTIC WASTEWATER TREATMENT SYSTEMS <br /> 14.The Recycled Water Policy includes monitoring requirements for Constituents of <br /> Emerging Concern for the use of recycled water for groundwater recharge by surface <br /> and subsurface application methods. The monitoring requirements and criteria for <br /> evaluating monitoring results in the Recycled Water Policy are based on <br /> recommendations from a Science Advisory Panel.4 Because this General Order is <br /> limited to non-potable uses and does not authorize groundwater replenishment <br /> activities, monitoring for Constituents of Emerging Concern is not required. <br /> 15.The Recycled Water Policy requires permits for landscape irrigation with recycled <br /> water to include priority pollutant monitoring at the recycled water production facility. <br /> Annual monitoring is required for design production flows greater than one million <br /> gallons per day; a five year monitoring frequency is required for flows less than one <br /> million gallons per day. Priority pollutants are listed in Appendix A of 40 Code of <br /> Federal Regulations (C.F.R.) Part 423. <br /> 16. Beneficial uses for groundwater are determined by each Regional Water Board and <br /> are listed in their respective Basin Plans. Beneficial uses for groundwater are: <br /> municipal supply (MUN), industrial service supply (IND), industrial process supply <br /> (PROC), fresh water replenishment (FRESH), aquaculture (AQUA), wildlife habitat <br /> (WILD), water contact recreation (REC-1), agricultural supply (AGR), and groundwater <br /> recharge (GWR). Some beneficial uses only apply to certain geographic areas within <br /> regions. <br /> 17. Basin Plans establish groundwater quality objectives to protect beneficial uses. The <br /> objectives may be narrative, numerical, or both. This General Order requires the <br /> Discharger to comply with those objectives in receiving groundwater. <br /> WASTEWATER DISPERSAL <br /> 18. Wastewater dispersal will occur by different methods. It may be percolated from <br /> ponds; applied to the surface by spray, flood, or drip methods; or discharged to a <br /> subsurface dispersal area such as a leachfield or seepage pit. The choice of disposal <br /> method will depend upon the amount of wastewater generated, the value of the <br /> wastewater for irrigation, and the receiving environment. <br /> a. Wastewater discharged to a pond for treatment and/or storage can result in <br /> groundwater degradation or nuisance odors. Ponds can also be vulnerable to <br /> damage caused by burrowing animals. <br /> 3 For this order, Constituents of Emerging Concern are defined to be chemicals in personal care products, <br /> pharmaceuticals including antibiotics, antimicrobials; industrial, agricultural, and household chemicals; <br /> hormones; food additives; transformation products, inorganic constituents; and nanomaterials. <br /> 4 The Science Advisory Panel was convened in accordance with provision 10.b of the Recycled Water Policy. <br /> The panel's recommendations were presented in the report; Monitoring Strategies for Chemicals of Emerging <br /> Concern in Recycled Water-Recommendations of a Science Advisory Panel, dated June 25, 2010. <br /> September 23, 2014 <br />
