Information Sheet IS-8 Reissued Waste Discharge Requirements General Order R5-2013-0122 Existing Milk Cow Dairies Water Quality Obiectives for Groundwater Water quality objectives that apply to groundwater include, but are not limited to, (1) numeric objectives, including the bacteria objective and the chemical constituents objective (includes state MCLs promulgated in Cal. Code Regs., tit. 22, §§ 64431 and 64444 and are applicable through the Basin Plans to municipal and domestic supply), and (2) narrative objectives including the chemical constituents, taste and odor, and toxicity objectives. The Tulare Lake Basin Plan also includes numeric salinity limits for groundwater. State Water Board Resolution 88-63 (The Sources of Drinking Water Policy) The Sources of Drinking Water Policy states that all surface waters and groundwaters of the state are considered to be suitable, or potentially suitable, for municipal or domestic water supply, except where the groundwater meets one or more of the criteria specified in the Basin Plan, including: a. The TDS exceeds 3,000 milligrams per liter(mg/L) (5,000 micromhos per centimeter(umhos/cm) electrical conductivity) and the aquifer cannot reasonably be expected by the Regional Board to supply a public water system; b. There is contamination, either by natural processes or by human activity(unrelated to a specific pollution incident), that cannot reasonably be treated for domestic use using either Best Management Practices or best economically achievable treatment practices; or C. The water source does not provide sufficient water to supply a single well capable of producing an average, sustained yield of 200 gallons per day. d. The aquifer is regulated as a geothermal energy producing source or has been exempted administratively pursuant to 40 CFR, Section 146.4. for the purpose of underground injection of fluids associated with the production of hydrocarbon or geothermal energy, provided that these fluids do not constitute a hazardous waste under 40 CFR, Section 261.3. Both Basin Plans include criteria for granting exceptions to municipal and domestic supply designations based on the Sources of Drinking Water Policy. The Tulare Lake Basin Plan also includes criteria for granting exceptions to the designation of beneficial uses for agricultural supply and industrial supply. The Tulare Lake Basin Plan specifies exceptions to the designated beneficial uses for some groundwater within the Tulare Lake Basin. Exceptions to the Sources of Drinking Water Policy are not self-implementing, but must be established in an amendment to the Basin Plan. Title 27 of the California Code of Regulations Title 27 of the California Code of Regulations prescribes minimum standards for animal waste at confined animal facilities. For surface water protection, Title 27 includes requirements for the design of containment facilities for both storm water and process wastewater and for adequate flood protection. For groundwater protection, the minimum standards in Title 27 require existing milk cow dairies to minimize percolation of wastewater to groundwater in disposal fields, apply manure and wastewater to disposal fields at reasonable agronomic rates, and minimize
