<br /> The San Joaquin County Environmental Health Department (EHD) is extending the date
<br /> for submitting a work plan for an ozone bench-scale test, and a work plan for performing
<br /> an eight-to-twelve hour dual-phase extraction pilot test at the above-referenced site from
<br /> June 15, 2009, to July 30, 2009. Mr. Sean Peacher of Winefield & Associates, Inc.
<br /> requested this extension by telephone on June 5, 2009.
<br /> To comply with the State Water Resources Control Board Resolution No. 2009-0042, the
<br /> EHD approves the semi-annual monitoring and sampling of monitoring wells: MW-1,
<br /> MW-2, MW-3R, MW-4, MW-8, MW-9, MW-17, MW-19, MW-20, MW-21, MW-22,
<br /> MW-23, MW-24, MW-25, and MW-27. Analyze groundwater samples collected from
<br /> these wells for total petroleum hydrocarbons quantified as gasoline (TPHg); benzene,
<br /> toluenei ethyl benzene, and total xylenes (BTEX); methyl tertiary-butyl ether (MTBE),
<br /> ethyl tertiary-butyl ether (ETBE), tertiary-butyl alcohol (TBA), tertiary-amyl methyl
<br /> ether(TAME) and di-isopropyl ether(DIPE).
<br /> The EHD approves the biennial monitoring and sampling of monitoring wells: MW-5,
<br /> MW-6, MW-7, MW-10, MW-11, MW-12, MW-13, MW-14, MW-15, MW-16, MW-18,
<br /> and MW-26. Analyze groundwater samples collected from these wells for TPHg and
<br /> MTBE, only.
<br /> Monitoring well MW-25 has not been sampled since June 2008 because the well can not
<br /> be located. This well must be found and sampled during the next sampling event. Also,
<br /> the EHD is not being notified when the sampling events will take place. You must notify
<br /> the EHD at least seventy-two hours prior to a sampling event so an inspector can be
<br /> present.
