<br /> On August 7, 2009, the San Joaquin County Environmental Health Department (EHD)
<br /> approved a request by Thrifty Oil Company (TOC) to reduce the sampling of monitoring
<br /> wells MW-4, MW-5, MW-6, MW-7, and MW-9 to annual sampling commencing the first
<br /> quarter of each year, starting in 2010. The remaining wells, MW-3, MW-10, MW-11 R, and
<br /> MW-12R were reduced to semi-annual sampling and reporting.
<br /> A search of Geotracker submittals has revealed that the last groundwater sampling event
<br /> conducted by TOC occurred on February 25, 2009. The last monitoring and sampling
<br /> report (Geo_Report), the last depth to water data (Geo_Well), and the last electronic
<br /> submittal of groundwater laboratory data (EDF) was for first quarter, 2009. Missing from
<br /> Geotracker are the required Geo_Report, EDF, and Geo—Well submittals for the second,
<br /> third, and fourth quarter 2009.
<br /> Additionally, the annual and semi-annual sampling events were to begin during the first
<br /> quarter 2010 (January, February, & March) under the EHD witness. The EHD has not
<br /> been contacted for an appointment to witness this required sampling event and no first
<br /> quarter 2010 submittals are on Geotracker.
<br /> You are not in compliance with directives and sampling/reporting requirements issued by
<br /> the EHD or UST regulations to submit data to Geotracker.
<br /> You are hereby directed to conduct a groundwater sampling event within 30 days of
<br /> the date of this letter.
<br /> All monitoring wells and all remediation wells with groundwater in them are to be sampled
<br /> for total petroleum hydrocarbons as gasoline (TPHg), benzene, toluene, ethylbenzene,
<br /> total xylenes (BTEX), methyl tertiary-butyl ether [MtBE], tertiary-butyl alcohol [TBA], di-
<br /> isopropyl ether [DIPE], ethyl tertiary-butyl ether [EtBE], tertiary-amyl methyl ether [TAME].
<br /> 1,2-dibromoethane [EDB], and 1,2-dicholorethane [DCA].
<br /> You are hereby directed to contact Michael Infurna at (209) 468-3454 with no less
<br /> than two working days notice to schedule an appointment for this sampling event
<br /> and to submit the Geo_Report for this event, the EDF, and the Geo Well to
<br /> Geotracker by July 17, 2010.
