WASTE DISCHARGE REQUIREMENTS -4- GENERAL ORDER FOR DISCHARGE OF GROUND WATER FROM CLEANUP OF PETROLEUM FUEL POLLUTION TO SURFACE WATERS 17. The Water Quality Control Plans encourage the disposal of wastewater on land where practicable, and require applicants for discharge permits to evaluate land disposal as an alternative. Where studies show that year- round land disposal is not practicable, the Board will require dischargers to evaluate dry season land disposal as an alternative. 18. The Board has considered antidegradation pursuant to 40 CFR 131.12 and State Water Resources Control Board Resolution 68-16 and finds that the subject discharges are normally consistent with those provisions. If the discharge is not consistent with these policies it will not be covered under this permit, but could have a separate permit. 19. On 11 April 1991 the State Water Resources Control Board adopted the California Inland Surface Waters Plan (ISWP) which is applicable to all surface water discharges outside of the Sacramento-San Joaquin Delta, as defined by Section 12220 of the California Water Code, and for areas within the Sacramento-San Joaquin Delta where the Regional Board has determined that the freshwater objectives contained in the ISWP should be applied. On 11 April 1991 , the State Board also adopted the California Enclosed Bays and Estuaries Plan (EBEP) which is applicable to all discharges within the Sacramento-San Joaquin Delta. As all portions of the Sacramento-San Joaquin Delta within the Central Valley Region provide freshwater habitat and drinking water supply, at least during periods of high Delta outflow, the fresh water quality standards contained in the ISWP will be applied to all discharges covered by this Order. 20. The ISWP establishes numeric receiving water limitations in Tables 1 and 2 to protect aquatic life and human health. Numerical effluent limitations, other than for benzene, are not required because the discharges are not likely to contain significant concentrations of any of the other substances listed in Tables 1 and 2. Effluent limitations are being established by this Order for benzene which will assure compliance with the receiving water limitations for benzene contained in the ISWP and EBEP. 21 . Monitoring and certification for other substances are not required because the discharges permitted are of low volume with no significant adverse impacts on water quality. Discharges in excess of 100,000 gpd will not be covered by this Order. 22. Statewide plans and policies potentially applicable to this discharge and not referenced in the Basin Plan include the "Policy Statement on Wastewater Discharge to Watercourses in Water Deficient Areas, Resolution No. 79-45" and the "Policy with Respect to Water Reclamation in California, Resolution No. 77-1" . 23. Effluent limitations, and toxic and pretreatment effluent standards established pursuant to Sections 301 , 302, 304, and 307 of the Clean Water Act (CWA) and amendments thereto are applicable to the discharge.
