Andrew: <br /> Per our phone conversation on 7/5/2023, EHD has several comments regarding what you have submitted by email: <br /> 1) No fee has been submitted. Please provide. Note EHD fee schedule has increased as of July 1, (available on our <br /> website). Submit the following: <br /> $810 (PE 2904)for the MFR, plus <br /> $162 x2 for the two well permit fee <br /> 2) EHD is quite concern since you/contractor had failed to meet the permit condition of grout inspection <br /> requirement when Well #1 was installed last year. For the new Well #2 (2 nested wells) EHD requires in writing <br /> on your letterhead that you and C57 contractor will adhere to the permit condition of inspection by EHD to <br /> verify each grout mix and witness placement of the grout at 1)the borehole bottom, 2) at the deep well sanitary <br /> well, 3) the shallower well sanitary seal,4) and the top cement sanitary seal <br /> 3) There is no authorization from Bradley to Andrew to sign the permit on their behave on. Please provide or have <br /> Bradley the C-57 sign the permit. <br /> 4) Please specify grout(s)to be used in your work plan. Due to the depth of these wells, EHD will require the <br /> contractor on site to demonstrate the grout has been properly mixed, has at least 20%or higher solid % if it's <br /> bentonite (using instrument such as mud balance) and testing of pH of the water per manufacturer's instruction. <br /> Best Regards, <br /> Jeff <br /> From:Andrew Francis<afrancis@lsce.com> <br /> Sent:Thursday,June 29, 2023 2:26 PM <br /> To: ehsitemitigation [EHD] <ehsitemitigation@sigov.org> <br /> Cc: Eddy Teasdale<eteasdale@lsce.com>; Wong,Jeff[EHD] <Jwong@sigov.org>; rodb@bradleyandsonsdrilling.com; <br /> Gregory Gibson <ggibson@ci.lathrop.ca.us> <br /> Subject: City of Lathrop ASR Test Hole/Monitoring Well #2 <br /> Hello, <br /> I have attached the Work Plan, Master File Record, and Boring Permit Application for the proposed test hole/monitoring <br /> well at 950 Stewart Road. <br /> Thanks, <br /> Andrew <br /> Andrew Francis, PG <br /> Project Hydrogeologist <br /> Luhdorff& Scalmanini, Consulting Engineers <br /> 500 First Street <br /> Woodland, CA 95695 <br /> Office (530)661-0109 <br /> Direct(530)207-5736 <br /> afrancis(&Isce.com <br /> https://link.edgepilot.com/s/6f60da06/aiS5Tt-oVkyugRa1 nXueaw?u=http:Hwww.lsce.com/ <br /> 3 <br />
