Harlin Knoll <br /> Public Health Services San Joaquin County <br /> ' 304-East Weber Avenue;Third Floor <br /> Stockton, CA 95202 <br /> Subject: Well Abandonment Work Plan, Beacon 513, 401 Kettleman Ln., Lodi, CA <br /> Dear Mr. Knoll: <br /> As we discussed in our May 12, 1998 phone conversation, Doulos Environmental Company <br /> (Doulos) has been contracted by Ultramar, Inc. (Ultramar)toi�abandon three monitoring wells at <br /> the subject site. <br /> Prior to pressure grouting the wells, the volume of grout needed to displace the pore space in the <br /> sand pack and the volume of the casing will be calculated. The wells will be pressure grouted by <br /> trimming a neat cement slurry from the bottom of the well to the surface. The actual volume of <br /> grout used will be recorded. The well boxes will then be removed and the casing will also be <br /> removed to approximately one foot below grade. Because this differs from the county's <br /> standards, Doulos is requesting a variance on behalf of Ultramar. <br /> i <br /> After the field work is completed, a letter report will be forwarded to your office within 45 days. <br /> Doulos has scheduled this work for May 22, 1998. If you have any questions regarding this"'a " <br /> matter please contact me at(916) 782-9054. <br /> Enclosed is a completed well destruction application, a site map and a check for $60.00. <br /> Sincerely, <br /> i <br /> DOULOS ENVIRONMENTAL COMPANY <br /> k <br /> V-D GAO <br /> Hal Hansen, R.G. #6697, C-57 #730042 w <br /> HEH/tjh HAL E.HANSEN <br /> No.6697 r <br /> enclosure �j► <br /> i pF C A��F <br />
