What are your thoughts on this-is this acceptable? <br /> Gabe <br /> From: McGovern, Cameron [mailto:Cameron.McGovern(c arcadis-us.com] <br /> Sent: Tuesday, September 30, 2014 12:50 PM <br /> To: Gabriel Gonzalez [EH] <br /> Cc: BWaite(abchevron.com; mcmillans52l%ahoo.com; Munn,Julie; Sobieraj, Justin <br /> Subject: 437 E Miner Ave., Stockton <br /> Hey Gabriel, <br /> The plan for tomorrow is to initially destroy a %inch well (SP-2A [120 ft.]) by the procedure outlined below: <br /> 1. 50 grain det cord will be placed in SP-2A from 20 feet below ground surface to total depth (120 ft.)as outlined in <br /> the blasting plans. <br /> 2. Once the det cord is set, Cascade will insert the''/: inch poly tubing to TD in order to tremie grout through the <br /> water column and grout from the bottom of the well up to surface. <br /> 3. Once grout has reached the surface, the tremie tubing will be extracted from the well and the well will be <br /> topped off with additional grout(as necessary). <br /> 4. The charge will then be detonated and Cascade will add grout,as needed. <br /> a. If Cascade is unable to extract the tremie tubing,the 50 grain det cord should adequately destroy the <br /> materials within the well casing as well as successfully perforate the well casing. <br /> If we are successful in destroying SP-2A in this manner, in concurrence with SJCEHD Inspector,ARCADIS proposes to <br /> destroy all remaining W and 1" wells on-site in the same manner outlined above. <br /> Please let me know if this method is acceptable to the SJCEHD. <br /> Thank you, <br /> Cameron <br /> -------------------- <br /> From: Gabriel Gonzalez [EH] [mailto:gagonzalezftcehd.coml <br /> Sent: Tuesday, September 30, 2014 8:43 AM <br /> To: McGovern, Cameron; BWaiteachevron.com; mcmillans521(5)vahoo.com <br /> Subject: 437 E Miner Ave., Stockton <br /> Good morning, <br /> I spoke with Adrienne about the idea of using nylon tubing as a tremie to grout wells,from the bottom up,with casing <br /> diameters of inch and 1 inch. She believes there's a good chance the tubing will get stuck in place during grouting, and <br /> 1 <br />
