Mike Infurna [EH] <br /> To: Jennifer Adler <br /> Subject: RE: Soil Borings <br /> thanks. . . <br /> and yes I see that you didn't make the full 200 as issued on the permit. Without counting <br /> them all since my time is limited, just how many of the proposed 200, and what numbers <br /> were they, did you get installed under permit #42123? <br /> I need to modify the permit to reflect the work done. Now permit #42123 states, "BB-121 <br /> to BB-200". I'll need the correct range DONE previously and what the NEW range of numbers <br /> will be. .please. <br /> once I'm clear with this, I'll approve the additional borings/permit extention. <br /> thank you. <br /> -----Original Message----- <br /> From: Jennifer Adler [mailto:JAdler@claytongrp.com] <br /> Sent: Wednesday, July 06, 2005 8:49 AM <br /> To: Mike Infurna [EH] <br /> Subject: RE: Soil Borings <br /> I gave you that one because it most clearly shows the site layout as a <br /> whole. We don't have current proposed boring maps. The ones attached <br /> are the most recent version we have. I'll just have to tell you where <br /> additional borings are planned, as well. <br /> Figure 6a: add borings over BB-8. BB-10, and BB-15. We plan to step <br /> out 25 feet in both lateral directions from BB-10 and BB-15. All <br /> borings are planned to extend to 20' bgs, and only soil samples will be <br /> collected. <br /> Jennifer <br /> Figure 6b: add borings over BB-51 and BB-57, as well as 25-foot <br /> step-outs on either side of BB-51. <br /> Figure 6c: BB-163 and BB-164 will straddle BB-162. Additional borings <br /> will be extended between BB-118 and BB-126, over BB-125, and 25-foot <br /> step-outs from BB-125. That adds up to 48 borings, beginning with <br /> BB-144, though perhaps numbered somewhat differently for convenience's <br /> sake. <br /> As you can see, we didn't get to the full 200 we originally planned (an <br /> estimate) We did BB-1 through BB-45 with EnProb, BB-46 was started with <br /> Enprobe and completed with Gregg, and BB-47 thruogh BB-143 were <br /> completed with Gregg. These additional borings will keep us well within <br /> the requested 120 borings with EnProb on the soil boring permit. <br /> Jennifer Adler <br /> Staff Consultant <br /> Clayton Group Services <br /> 6920 Koll Center Pkwy. <br /> Suite 216 <br /> Pleasanton, CA 94566 <br /> (925) 426-2662 <br /> fax (925) 426-0106 <br /> 1 <br />
