DTSC hereby grants conditional approval as the workplan meets the objectives <br /> set by DTSC's request of August 1, 1996; however, DTSC would like the following <br /> additional requirements incorporated into the workplan: <br /> • Six (6) additional soil vapor sampling points be included north of and along the <br /> six (6) inch sanitary sewer line. The additional sampling points are identified <br /> on the enclosed Figure 3 revision of the subject document. As noted on <br /> Figure 3, two (2) locations were deleted in lieu of the new required locations. <br /> • At least three (3) additional soil vapor samples be collected within the area <br /> identified in Figure 2 of the workplan as the former Insurance, Tax, Real Estate <br /> and Beauty Shop structure. Photos taken of this area indicate that the area was <br /> once unpaved open space. Samples collected in this area are necessary to <br /> determine if disposal of perchloroethylene was made directly to the ground in <br /> +this area. <br /> • Verification must be provided which shows that in fact Norge Laundry & <br /> Cleaning and Deluxe Dry Cleaners operated within the same physical location <br /> and/or structure as indicated in the workplan. Official records such as <br /> city/county assessment or property tax records identifying each business' actual <br /> location, or any other documentation showing the same, will suffice. <br /> DTSC would like to thank you for your timely response to the <br /> August 1, 1996 request. Please submit the revised workplan to us by <br /> October 28, 1996. DTSC would like to be notified at least five (5) days prior to <br /> implementing the approved workplan. <br /> L � <br />
