PUBLIC HEALTH SERVICES <br /> PpU1ly <br /> SAN JOAQUIN COUNTY <br /> 2.. <br /> ENVIRONMENTAL HEALTH DIVISION Z< <br /> Ernest M. Fujimoto, M. D., M.P.H., Acting Health Officer <br /> 304 E. Weber Ave., Third Floor • P. O. Box 388 • Stockton, CA201 <br /> 209/468-3420 lj <br /> JOHN JOHNSON MAILED FEB 0 61996 <br /> THE CUSTOMER COMPANY <br /> P O BOX 886 <br /> BENECIA CA 94510 <br /> RE: FOOD AND LIQUOR SITE CODE: 1984 <br /> 890 NORTH MAIN <br /> MANTECA CA <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS-EHD) is pleased to <br /> provide this letter regarding the status of the request for site closure recently submitted for the above <br /> noted facility. <br /> As you know, in 1993 PHS-EHD requested that you provide additional data to support the conclusion <br /> that the residual levels of hydrocarbons remaining at the site are limited and do not pose a significant <br /> threat to groundwater. Since that time, the soil and groundwater data from the site appear to strongly <br /> support this initial conclusion. PHS-EHD appreciates your efforts in providing this additional data. <br /> PHS-EHD has received the request for closure prepared by your consultant, Parker Environmental. <br /> Staff review of the request for closure is complete and is favorable. The request will now be further <br /> reviewed by our internal peer review committee. The peer review will evaluate the need to continue <br /> monitoring at the site or if a regulatory closure is warranted at this time. Should PHS-EHD concur with <br /> the closure request, 30 days notice of the impending closure will be provided to the Central Valley <br /> Regional Water Quality Control Board (CVRWQCB). Unless the CVRWQCB has justifiable concerns <br /> about the closure, PHS-EHD will issue a formal closure letter after the destruction of the site <br /> monitoring wells. The time frame for the above noted process is roughly 60 to 90 days. <br /> Considering that the bulk of the impacted soil had been removed by over-excavation in 1987 and that <br /> subsequent groundwater monitoring over time has indicated predominantly nondetectable levels of <br /> contamination, a strong argument for a no further action decision can be made at this time. In any <br /> event, you can be assured that this site is in the final phase of regulatory oversight, with a formal <br /> closure expected some time in the near future. <br /> It is hoped that this letter will be of help to you. If you need anything further or wish to discuss this <br /> letter in more detail, please contact Linda Turkatte, Senior REHS, at (209) 468-3441. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> Linda A.
