Your drawing suggests that the combined length of the <br /> grout AND the bentonite is only 1 .5 feet (18"). Is it six inches of <br /> bentonite and one foot of grout? or one foot of bentonite and six <br /> inches of grout? The reason I question this is that you may side <br /> step the 2" grout annulus requirement if there is NO grout. We allow <br /> shallow wells like this to have the the contents extended upward so <br /> that the top of the hydrated bentonite will be the bottom of the <br /> CONCRETE used to set the box. If you think it'll work for you, you <br /> can extend the bentonite to one foot leaving the 6 inches to be <br /> included in the concrete you'll use to set the box. NO GROUT...no <br /> need to expand the borehole to 6" at the top. make sense? <br /> 3-Back in 2008, billing party info was sent to the EHD on our MFR <br /> form. Since that time, our billing has come back to us as <br /> undeliverable at the address you provided. Please verify the name <br /> and address of the billing party that WILL ACCEPT the EHD billing <br /> over and above the $375 (3-hours prepayment) you sent in this time <br /> (check #2032565 plus $89 for the boring permit). <br /> From: MacLeod, Max [mailto:Max.MacLeod@lfr.com] <br /> Sent: Wednesday, July 01, 2009 3:10 PM <br /> To: Mike Infurna [EH] <br /> Cc: Seyfried, Scott; Goldstein, Lucas <br /> Subject: Four proposed soil vapor wells, 10'- 10.5' deep at Robinhood plaza <br /> Mr. Infurna: I spoke with you a few weeks ago about installing four soil vapor <br /> 7/8/2009 <br />
