page 2, 515 Charter Way <br /> which fits the description of the tank removed on February 7, 1996. Shaw has deduced <br /> that it was a waste oil tank based on the results of the analysis of soil samples collected at <br /> the time of the tank removal. These analytical results were positive for TPHd and motor <br /> oil, but there is no documentation in the file, and SJC/EHD has no knowledge, of there <br /> ever being more than one UST located at this site. The history of the tank removed from <br /> this site is not known to SJC/EHD. You, Mr. Rodgers, registered this tank with SJC/EHD <br /> in 1996, describing it on his application as a "550 gallon leaded gasoline tank",just prior to <br /> having it removed. <br /> Effective July 1, 2005, California Code of Regulations Title 23, Division 3, Chapter 30 was <br /> expanded to include the requirement that all reports of work performed at contaminated <br /> underground storage tank sites, including quarterly monitoring and reporting and site <br /> investigation reports, must be submitted electronically to Geotracker, the State Water <br /> Resources Control Boards data information website. Previously, only laboratory data from <br /> chemical analysis of samples, well elevation survey data, site maps and measured <br /> groundwater elevation data were required to be electronically submitted to Geotracker. <br /> Please proceed with submittal of all reports of work completed at your site to Geotracker. <br /> In summary, the following must be done for this site to be considered to be in compliance <br /> with regulatory directives: <br /> 1. Continue routine quarterly groundwater monitoring and sampling until directed <br /> otherwise by this agency. The approved modified schedule may be <br /> implemented, and may include switching to annual monitoring of wells MW-2R <br /> and MW-3R <br /> 2. Prepare a work plan to continue the investigation of the vertical extent of the <br /> contamination at this site, in both soil and groundwater. The work plan is due <br /> for submittal to SJC/EHD no later than March 30, 2007. <br /> 3. Submit a feasibility study for remediation of the groundwater contamination <br /> present onsite. The feasibility study is due for submittal no later than <br /> March 30, 2007. <br /> If you have any questions please call Lori Duncan at (209) 468-0337. <br /> Donna Heran, REHS, Director <br /> Environmental Health Department <br /> Lori Duncan, Senior REHS Nuel C.
