<br />San Joaquin County Environmental Health Department (EHD) has reviewed Work Plan for
<br />Soil Investigation Beneath Former UST's (Work Plan) dated August 25, 2008, submitted on
<br />your behalf by Ground Zero Analysis, Inc. (Ground Zero) and has the following comments.
<br />In the Work Plan Ground Zero proposes the advancement of five direct push soil borings to
<br />total depths of 25 feet below surface grade to collect soil samples for laboratory analysis.
<br />The soil samples will be collected from areas believed to be beneath the former underground
<br />storage tanks (USTs) and between the former dispenser island and boring B-4, which was
<br />installed in 1996 as part of a different investigation.
<br />The EHD approves the Work Plan with the condition that the soil sample analytical suite
<br />includes the following:
<br />1. Total petroleum hydrocarbons as gasoline and diesel by EPA Method 8015.
<br />2. Benzene, toluene, ethylbenzene and total xylenes by EPA Method 8020 (or 8260).
<br />3. Total lead by EPA Method 7420.
<br />4. Methyl tertiary butyl ether, tertiary butyl alcohol, di -isopropyl ether, ethyl tertiary butyl
<br />ether, tertiary amyl methyl ether, 1,2-dichloroethene and ethylene dibromide by EPA
<br />Method 8260.
<br />Please proceed with submittal of an EHD soil boring permit application and required $89.00
<br />permit fee; an EHD Master File Record Form and $315.00 site mitigation fee for report
<br />review and inspections (staff time billed at $105 per hour), and with scheduling the approved
<br />work. Deadline for implementation of the Work Plan is November 7, 2008; the report of
<br />findings documenting the results of the investigation is due for submittal within 60 days
<br />following completion of the fieldwork. If you have any questions please call Lori Duncan at
<br />(209) 468-0337.
