Charter Way CUF#: 0552 <br /> Stockton , CA, 95206 APN : 163-230-39 <br /> The San Joaquin County Environmental Health Department (EHD) has reviewed Interim <br /> Remediation Work Plan — March 2009 (TRAP ) submitted to Geotracker on April 6 , 2009 <br /> by your consultant Advanced GeoEnvironmental and has the following comments . <br /> The IRAP was prepared in response to the January 23 , 2009 EHD comment letter <br /> approving AGE's conclusion that dual phase extraction (DPE) would be the most <br /> feasible and cost effective remedial action for this site and requested a work plan be <br /> submitted . <br /> The IRAP includes a proposal to install , operate and maintain an interim DPE <br /> remediation system utilizing existing site wells, EW-1 , VW- 1 , and AW-1 . The IRAP is <br /> adequate and necessary and approved . [H&S Code 25296 . 10 (c)(3)] . <br /> Although the IRAP is approved , the EHD still requires you to continue your investigation <br /> to define the lateral and vertical extents of impacted soil and ground water. <br /> A recommendation included in the Site Conceptual Model (SCM ) was to continue the <br /> investigation in the Deep Unit (90- 115' below ground surface) to further define the <br /> dissolved petroleum contamination present at this depth and possibly deeper. The EHD <br /> concurs . <br /> Additionally, the lateral extent of hydrocarbon—impacted soil has not been defined <br /> toward the northeast, east, southeast or south of the former underground storage tank <br /> (UST) area, or northwest of MW-2 . Additional investigation is needed in these areas, as <br /> well as in the Deep Unit, and should be conducted very soon after the DPE system is <br /> online and operational . A work plan to continue the investigative phase for this site is to <br /> be submitted to the EHD within 90 days of the start up of the DPE system . <br />
