I like one size larger, <br /> but I can't enforce that. IF unknown, best to go with large augers to be sure to remove all contents that were <br /> installed. You'll need to verify the diameter of the hardened grout. <br /> From: Richard Gandolfo [mailto:rgandolfo@engeo.com] <br /> Sent: Thursday, June 18, 2009 8:52 AM <br /> To: Mike Infurna [EH] <br /> Subject: RE: Lathrop Piezometer <br /> I was going by the recommendation from Adrian at the EHD office. What would be the appropriate <br /> overbore for the ''/� pipe? <br /> The original bore appears to be 6 inches. <br /> I'll contact you when I get more information. <br /> Richard <br /> From: Mike Infurna [EH] [mailto:MInfurna@sjcehd.com] <br /> Sent: Thursday, June 18, 2009 8:45 AM <br /> To: Richard Gandolfo <br /> Subject: RE: Lathrop Piezometer <br /> Richard, <br /> I'm not sure who OWNS this well. any thoughts? My closest site there is California <br /> Natural Products, 1250 E. Lathrop Rd. They are conducting a ground water <br /> investigation under the CVRWQCB lead, Tim O'Brien the contact. They have wells, <br /> piezos, etc all around the site. I can't find this one based on your description, but I have <br /> doubts that it's removal will go unnoticed and I'm reluctant to issue a destruction permit <br /> until I feel more confident about who owns it. Kleinfelder is consulting for CNP, Joe Zilles <br /> is the contact. I recommend you contact them to verify that this well/piezo is NOT <br /> theirs/not needed. <br /> I'm under the impression this well is in the County right of way/roadside. true? if so, you'll <br /> need a SJ County Public Works Encroachment permit to gain access to destroy it. have <br /> you checked with Public Works for the encroachment permit that installed it? you should. <br /> why 12" overbore? why so large? are you under the impression a 12" auger installed <br /> this 1/2 inch well? If not, I will approve the same size auger or one slightly larger for he <br /> o/bore. <br /> 2-3 what? weeks? days? months? <br /> a Master File Record (MFR) is to be submitted with the $315. I've attached one here, as <br /> 6/18/2009 <br />
