Nuel only approved the grout ratio. <br /> Michael <br /> From: Rogers, Tamera [mailto:Tamera.RogersCcbarcadis.com] <br /> Sent: Monday, April 17, 2017 4:21 PM <br /> To: Michael Kith [EH]; Granborg, Jennifer <br /> Subject: RE: Well Destruction Permits (Site and Right of Way) - 351515 4707 Pacific Avenue, Stockton - Additional items <br /> requested by County <br /> Section 13.12.5 of the SJC Well Standards states: "Neat cement grout shall be mixed at a ratio of one 94-pound sack of <br /> Portland Cement to 5- 10 gallons of potable water." <br /> The purpose of using the smaller sacks of Portland cement is related to H&S. As I am sure you are aware, proper lifting <br /> procedures require a second person for lifting anything over 50-pounds in weight. A 94-pound sack mixed with 5- 10 <br /> gallons of water allows for a lot of variation in the thickness of the neat cement as it enters the well for destruction (no <br /> matter what method is utilized). I just personally looked up the Quikrete sack weight and it appears we can get 47- <br /> pound bags of Portland cement. If we take the two 47-pound bags we get to the 94-pound sack equivalent (even at 46 <br /> we are at 92-pound sacks). If we double the 4-gallons for 1 sack to 8-gallons for 2 sacks we are at 94-pounds for 8 gallons <br /> of water which puts us perfectly in-line with the SJC Well Standards. So the grout ratio shouldn't be a concern. Nuel <br /> understood what I was stating by using the lighter weight sack which is why it was conditionally approved. <br /> Also, please take into consideration the other comments discussed in my original email now that the grout ratio has <br /> concern has been resovled. <br /> Cheers <br /> Tamera Rogers, GIT I AFS Project Manager I Tamera.Rogers@arcadis.com <br /> Arcadis I Arcadis U.S., Inc. <br /> 6296 San Ignacio Ave, Ste C & D San Jose CA 195119 1 USA <br /> T. +1 408 797 20131 M. +1 408 239 9616 <br /> Connect with us! www.arcadis.com I Linked n Twitter I Facebook I <br /> PARCADIS! ,,, ..a <br /> EXPLOREArcadis co <br /> DOWNLOAD OUR MOBILE APP CT <br /> Be green,leave it on the screen. <br /> From: Michael Kith [EH] [mailto:mkith@sjcehd.com] <br /> Sent: Monday, April 17, 2017 4:05 PM <br /> To: Rogers,Tamera <Tamera.Rogers@arcadis.com>; Granborg,Jennifer<Jennifer.Granborg@arcadis.com> <br /> Subject: RE: Well Destruction Permits (Site and Right of Way) -351515 4707 Pacific Avenue, Stockton -Additional items <br /> requested by County <br /> 5 <br />
