Grewal <br /> Associate Air Pollution Engineer EUVIROMENTAL HEALTH, <br /> Sari Joaquin County F£RMIT/SERVICES, <br /> 1501 East Hazelton Avenue <br /> Stockton, CA 95201 <br /> Dear Mr. Grewal: <br /> Please find attached, for your approval, a drawing and description <br /> of a hydrocarbon recovery system that includes an air stripping tower. <br /> The purpose of the air stripping tower in this system -is to volatize <br /> off very low levels of soluable hydrocarbons that have become involved <br /> with the groundwater due to a hydrocarbon leak. The soluable hydro- <br /> carbon levels introduced to the stripping unit ,should never exceed the <br /> (PPM) parts per million range and in most cases would riot exceed the <br /> (PPB) parts per billion range. At -no time would phased product (raw <br /> hydrocarbon) be allowed to enter the air stripping system. <br /> Due to varying groundwater conditions and recharge rates, pumping rates <br /> and blower speeds will have to be calibrated to the site specific- situa- <br /> tions to achieve the optimum results,--' but at no time will the stripping <br /> tower air discharge exceed air quality standards-. <br /> If you have any questions relating to this system that I may answer for <br /> you, I would be very happy to do so. Please direct all responses to my <br /> new local address: <br /> James R. Fox <br /> 2243 Rosemarie Lane— Apt. 120 <br /> Stockton, C& 95207 <br /> (209) 951-0232 <br /> Thank you for your time to review this system. Your favorable response <br /> to this request will be most appreciated. <br /> Sincerely, <br /> James R. F x <br /> Project Manager <br /> JRF/ca <br /> Attachment <br />
