Groundwater VOC and Fuel General Permit ORDER NO.R2-2012-0012 <br /> NPDES NO.CAG912002 <br /> I. SCOPE OF GENERAL PERMIT <br /> Facilities that may be covered under this Order are groundwater treatment facilities located at active or <br /> closed sites, such as service stations or construction sites. These groundwater treatment facilities are in <br /> operation to extract and treat groundwater polluted by volatile organic compounds (VOC), fuel, and fuel <br /> additives. This Order covers discharges from these facilities to all surface waters such as creeks, <br /> streams,rivers including flood control channels, lakes, or San Francisco Bay. Such discharges may <br /> occur directly to surface waters or through constructed storm drain systems. <br /> II. FINDINGS <br /> The California Regional Water Quality Control Board, San Francisco Bay Region(hereinafter, the <br /> Regional Water Board), finds: <br /> A. Background.

Of this group, 18 submitted Notices of Intent(NOI) applications and applied <br /> for an NPDES permit to continue their discharge of treated wastewater from their groundwater <br /> extraction and treatment facilities(hereinafter Facility or Facilities). <br /> In addition, there are 56 permittees currently authorized to discharge pursuant to Order No. R2- <br /> 2009-0059, NPDES Permit No. CAG912003 (General Waste Discharge for Discharge or Reuse <br /> of Extracted and Treated Groundwater Resulting from the Cleanup of Groundwater Polluted by <br /> VOC). Order No. R2-2009-0059 will not be reissued upon expiration on September 30, 2014, <br /> and permittees with a continued need to discharge shall seek coverage under this General Permit. <br /> For the purposes of this Order, references to the "Discharger" or"permittee" in applicable <br /> federal and State laws, regulations,plans, or policy are held to be equivalent to references to the <br /> Discharger(s)herein. A discharger who is authorized under this Order is hereinafter a <br /> Discharger. <br /> B. Facility Description. Dischargers typically use aeration and/or granular activated carbon(GAC) <br /> systems to treat their groundwater prior to discharge. Facilities that use other types of treatment <br /> systems that are effective at removal of VOC or fuel pollutants may be covered by this Order <br /> subject to the approval of the Executive Officer. Treated wastewaters are typically discharged <br /> through storm drain systems, rivers, and/or creeks to San Francisco Bay. To obtain coverage <br /> under this Order, a discharger must include a complete description of the treatment system <br /> installed at its facility in the Notice of Intent(NOI) application form(Attachment B). <br /> C. Regional Water Board Preference for Reuse or Discharge to POTW: The Regional Water <br /> Board adopted Resolution No. 88-160 on October 19, 1988. The Resolution urges dischargers of <br /> extracted groundwater from site cleanup projects to reuse their treated groundwater. When reuse <br /> is not technically andlor economically feasible, to discharge to a publicly owned treatment works <br /> (POTW). Only if neither reuse nor discharge to a POTW is technically or economically feasible, <br /> and if beneficial uses of the receiving water are not adversely affected, the Regional Water <br /> 3 <br /> Limitations and Discharge Requirements <br />
