The <br /> wells will be properly abandoned in accordance with requirements of the San Joaquin <br /> County Environmental Health Department(SJCEHD). The wells will be abandoned by <br /> drilling out the existing casing and sand-pack to the total depth of the well, and <br /> backfilling the boring with neat cement. A representative of the SJCEHD will be present <br /> to approve grouting operations. A copy of the monitoring well construction logs is <br /> presented as Attachment A. Upon completion of the well abandonment, Clayton will <br /> submit a report to the RWQCB documenting the well abandonment activities. <br /> Should you have any questions,please call me at 925.426.2673. <br /> Sincerely, �ERED Gfp4�/� <br /> MICHAEL HURD <br /> Na. 0068 <br /> CERTIFIED <br /> Michael Hurd, CHG 0068 HYDROGEOLOGIST <br /> Senior Project Manager. ^ EXP.
