L.pdf{524 KB) <br /> Ms. Mccartney: <br /> Please see below Jim Barton's concurrence of the tenth well proposed at the Jimco Truck <br /> Plaza in Ripon. Calvin advised me that you will modify the permit to include this tenth <br /> well once you receive the RWQCB concurrence of its installation. I have attached our site <br /> plan showing the location of this well, although Calvin may have already provided this to <br /> you. The well in question is located directly north of the word PROPOSED in the title <br /> block and just northeast of boring B-32 . <br /> Feel °free to contact me if you have any questions regarding this. <br /> Thanks for your help. <br /> Robert C.

The <br /> site plan is 1"=60 ' since the site is so big. <br /> Section 9 - Proposed Site Assessment Activities in the CAP document states that one of the <br /> objectives of this work is to determine the extent, <br /> potential thickness and volume of SPH <br /> in the vicinity of the diesel ASTs. That is why we are proposing to install a well in <br /> this location, since the dissolved TPHd concentration was so high we believe we will find <br /> SPH in this area.
