CLEANUP AND ABATEMEN't ORDER NO. 5-00-704 FORMER CHEVRON STATION #9-5775 A010 1 "FEST- KETTLEMAN LANE DI, SAN JOAQUIN COUNTY hours. GR is scheduled to continue Nveekly extraction at EX -1 until an interim pump and treat system is installed. 5. On 7 April 2000, GR submitted a workplan to the San Joaquin County Environmental Health Division to install six additional monitoring wells to further define the lateral and vertical extent of petroleum hydrocarbons and fuel oxygenates both on-site and offsite. One deep monitoring well will be installed next to MW -8 to sen•e as a sentinel well between the on-site contamination and the active City of Lodi -Municipal Well 12 (City Well 12). G. City Wel l 12 is about 500 feet southwest and downgradient of the fonrter underground storage tanks. City Well 12 operates intermittently- at approximately 800 gallons per minute. The well is constructed with a 108 -foot annular seal; cased to 490 feet bgs without a gravel pack, and the first perforated interval is at 210 feet bgs. The City of Lodi Water Department analyzes monthly samples from City Well 12 using EPA Method 524.2. MtBE has not been detected in this well at a detection limit of 3 /1. 7. In October 1999, GR placed water level transducers in two do -site monitoring wells for a 3 -day period and recorded fluctuation changes corresponding to pumping of City Well 12. GR concluded that the shallow groundwater zone is in conununieation with the municipal well. S. The California Department of Health Sen'ces Drinking Water p -� ranking Wat Accton Level for MtBE is. 13 µg/l, and the Secondary Maximum Contaminant Level for taste and odor is 5 µg/1. 9. Section 13304(a) of the California Water Code provides that: Any person who has discharged or disdharges sv=e into the wters of this stare in violation of -any waste discharge Muirement or other order or prohibition issued bz- a rrsional board or the state board, or who has caused orperrnflted, causes or permits, or threatens to cause or permit anti- %-%we to be discharged or deposited where It is, orprnbably will be, di rcharged law the waters of the state and awaits, or threatens to orate, a condition ofpolludon or Aulsamm shall sqvn order of dee anconal board crewW such wage or abau the ejeds of the uvWe, on to the case of threa%em4p Qaion or m&awer take other necessary remedial action, lydudmg, but not limited to, overseeing cleanup and abatement e,(jorls Upon failure of any person to eompb, with the cleanup and abatement order, die Attornry General; at the request ofthe board, "petition- the superior court for that couno- for the ft wane of an iVunctlon requiring the perron to damply with the order.

The Water Quality Control Plan for the Regional Water Quality Control Board, Central Valley Region, (4th Edition) (Basin Plan) establishes beneficial uses and water quality objectives to protect the beneficial uses. Water quality objectives for groundwater as specified in the Basin Plan include pritnary and secondary maximum contaminant levels. Waste, including MIKE, has been discharged to waters of the state at concentrations that exceed water quality objectives. Exceedmee of water quality objectives constitutes pollution. Therefore, waste, including MTBE, has been discharged or deposited where it has cheated and continues to threaten to create a condition of pollution or nuisance. 2
