FACT SHEET, ATTACHMEPC • _ WASTE DISCHARGE REQUIREMENTS ORDER NO. 5-00- -12 CITY OF LODI WHITE SLOUGH WATER POLLUTION CONTROL PLANT SAN JOAQUIN COUNTY 1) Reclamation The California Department of Health Services has established statewide reclamation criteria in Title 22, California Code of Regulations, Section 60301, et seq. (hereafter Title 22) for the use of reclaimed water and has developed guidelines for specific uses. The Board has consulted with the Department of Health Services, San Joaquin County Mosquito Abatement District and considered their recommendations regarding public health aspects for use of reclaimed water. This Order contains Specifications that require compliance with the guidelines developed in conformance with Title 22. m) Groundwater The Discharger has installed seven groundwater monitoring wells in order to conduct monitoring of ground water upgradient and down gradient of the wastewater treatment facilities and the reclamation and biosolids disposal areas. This Order requires the Discharger to submit a report regarding the adequacy of the existing wells for this purpose, and the need for additional wells. Plans and specifications for any additional wells must be submitted for review and approval prior to construction. Any additional reclamation and/or biosolids disposal areas need adequate wells in place and monitoring initiated for at least one year prior to use of those areas. If monitoring of the groundwater indicates that the discharge has caused an increase in constituent concentrations at the point of compliance, as compared to background, the Discharger will be required to conduct a study of the extent of groundwater degradation. If the study indicates the discharge has incrementally increased concentrations in groundwater, enforcement actions may be pursued and/or the permit may be reopened and modified. Points of compliance will be established as near to the discharge areas as practical, but shall not extend beyond property owned or controlled by the Discharger. n) Biosolids The Discharger currently mixes biosolids from the treatment plant with the effluent from the industrial wastewater holding ponds and effluent from the treatment plant, and discharges it to the 950 acres of City-owned agricultural fields surrounding the plant. The United States Environmental Protection Agency (EPA) has promulgated biosolids reuse regulations in 40 CFR 503, Standards for the Use or Disposal of Sewage Sludge, which establish management criteria for protection of ground and surface waters, set application rates for heavy metals, and establish stabilization and disinfection criteria. The Board is using the Standards in 40 CFR 503 as guidelines in establishing this Order, but the Board is not the implementing agency for the 40 CFR 503 regulations. The Discharger may have separate and/or additional compliance, reporting and permitting responsibilities to EPA, which are not covered by this Order.
