Box 2009 <br /> Stockton, California 95201 <br /> Subject: Sierra-Pacific Groundwater Consultants, Inc., Proposed Installation of a Monitoring Well <br /> (MW--10) and Decommissioning of a Monitoring Well (MW-4) at 1905 North Broadway <br /> Avenue, Stockton,Former PureGro Site No. 771165, Unocal Order/Contract:3400003285, <br /> Sierra-Pacific Project No. 94-055.03 <br /> Dear Mr. Infurna: <br /> Draft copies of Sierra-Pacific's work plan for installation of an up-gradient monitoring well (MW- <br /> 10) in the northeast corner of the 1905 North Broadway Avenue site, and the work plan to <br /> decommission monitoring well MW-4,located within the former PureGro (south) evaporation pond <br /> area, are enclosed for your review and consideration. <br /> Each project would require approximately one day to complete. MW-10 would be constructed with <br /> a flush-mounted wellhead, and we may have to do the work on a weekend to minimize traffic <br /> disruption. MW-4 must be decommissioned to accommodate further remediation. Sierra-Pacific <br /> will submit applications for SJCEHD permits to install MW-10 and decommission MW-4 as soon <br /> as the work plans have been approved by you and Wendy Wyels. <br /> Please take a look at the draft work plans. Give me a call if you have questions or <br /> recommendations. <br /> Sincerely, <br /> IERRA-PACIFIC GROUNDWATER CONSULTANTS, INC. <br /> John Stephen pp, 13 3 <br /> or Engine ring eologist <br /> JSR:cf <br /> Enclosures <br /> C.
