<br /> Re: 1 W. Turner Road, Lodi , .CA
<br /> Pursuant to Federal Regulation CFR-40'for public information,
<br /> Ford Construction Company, Inc. and Jim Thorpe Oil , Inc. submit .the
<br /> following summary as to site mitigation,, corrective actions taken and
<br /> proposed for public perusal . ::
<br /> I
<br /> In December, 19871 an underground de'sel :fuel tank was removed at the
<br /> aforementioned address on behalf- of the property owners, Italian' Swiss
<br /> Colony Wines , Inc. , by Jim Thorpe Oil , Inc:: It was discovered at the time
<br /> of removal that the tank had been leaking and 'significant soil contamination
<br /> had resulted. A soil and groundwater investigation was performed by Ground-
<br /> water Technology, Inc. , Sacramento office. ~ Eight soil borings were done and
<br /> three monitoring wells were installed.. The plume of contamination was defined.
<br /> The property was purchased -by Ford Construction Company, Inc. and Jim Thorpe
<br /> Oil , Inc. in July, 1988. Excavation of contaminated soil was started mid,
<br /> February, 1989, and finished March'l., 1989. All soil excavated ,is stockpiled
<br /> on site awaiting disposition. Subsequent testing revealed no groundwater i
<br /> contamination, and no soil contaminationremaining 'in the former, tank area. '
<br /> Contaminated soil was' then self-certified as non-hazardous by use of a Fish
<br /> Bio-Assay and STLC for 17 metals on samples taken directly from 'diesel contam-
<br /> inated soil . All samples passed as acceptable levels or within tolerance
<br /> according to California State Division-of Toxics Title .22 Guidelines.
<br /> Ford Construction Company, Inc. :and' Jim Thorpe Oil ,. Inc. now propose
<br /> to finish the site mitigation by taking the final corrective action step.
<br /> We propose a bio-remediation on the remaining stockpiled soil . This process
<br /> will be performed and accomplished in a "point venture by Ford Construction
<br /> Company, Inc. , Jim Thorpe Oil , Inc. , and'. Terra Environmental Services , Inc.
<br /> The process consists of inoculating the contaminated soil with hydrocarbon
<br /> reacting microbes , nutrients, and water..', Then monitoring levels of hydro-
<br /> carbon over a period of- time: Ideally':, non-detectable levels will be strived
<br /> for; however, levels of hydrocarbons of 100. ppm or less with .no benzene,
<br /> ethlybenezene, toluene, or xylene will be acceptable and will allow for the
<br /> use of the soil under the streets and sidewalks of the planned developement.
