LATOuRETTE <br /> ORCHARD SUPPLY HARDWARE <br /> P O. BOX 49027 <br /> SAN JOSE CA 95161-9027 <br /> RE OSH SITE CODE. 2287 <br /> 8715 w GRANTLINfE ROAD; TRACY <br /> The recent report submitted by Clayton Environment, , ,enc.. for Orchard Supply <br /> Hardware recommends additional sail barLngs be drilikqA•in-and around the recently <br /> replaced Monitoring well 38. The soil contamination documented during the <br /> drilling of the monitoring well 38 at depths of 4 feet and 9 feet indicated the <br /> presence of heavy petroleum products, oil and grease. The water sampling <br /> collected from the monitoring well 38 did not detect contaminates exceeding MCL'6 <br /> (maximum contaminate levels). <br /> we agree that additional soil borings would benefit the overall site's definition <br /> and help to determine the need for additional soil removal or whether long-term <br /> groundwater monitoring would best suit this site. <br /> In a telephone conversation between Clayton Environmental, Inc. and a member of <br /> my staff, various laboratory analyses were discussed which may provide for better <br /> determination of the oil and grease (i.e., 418.1 or 5520, formerly known as 503) <br /> The selection of the analysis should be one that would provide solubility <br /> results (waste Extraction Test, Title 22) rather than analyses which vary in <br /> detection limits and also vary in quantitative results (both methods for oil and <br /> grease have interferences which may mask the presence of volatile <br /> constituents) . <br /> f In addition, the check 053791 issued 12/10/90 For the septic and well destruction <br /> s for the neighboring parcel, address 8885 W. Grantline Road, will be returned to <br /> Clayton Environmental, Inc. The amount of check 053791 exceeded the amount due. <br /> f for a now check in the amount of $134.00 <br /> Clayton Environmental will arrange <br /> it to Health(574.00 + $68.00) and that the permit Public <br /> may takesplacoironmencal Health <br /> Division (PHS/RHD) <br /> be mailed to <br /> n Svironmeftt&I, Inc-, 80 <br /> Permit application® sl boring drilling eannd to PHS-BHD <br /> be returnedhat <br /> details of the Proposed <br /> review prier toe"lanemay be referred to inthe field ipyrevicu lrk yian a submitted cworkand <br /> plan <br /> health and salafiy„p <br /> documents. <br /> If you have any questions, contact Diane Hineon, Supervising RZHS, of my staff <br /> at (209) 468-3452. <br /> ` Jogi Kha Mzie. <br /> OM.P.H. <br /> Health y�, ewe <br /> a LOnA. cotProgr �na9er <br /> �.
