Box 2009 <br /> Stockton, California 95201 <br /> Subject: Workplan for Well Abandonment at Former BJJ Company Site, 757 East 11th <br /> Street, Tracy, California <br /> Dear Mr. Knoll: <br /> Smith Environmental has prepared this letter to serve as a workplan for the proposed abandonn>ent of <br /> groundwater monitoring wells MW2 and MW3 at the above referenced site. A permit application and <br /> associated fee is attached. Upon receipt of the well destruction permit, Smith Environmental will <br /> schedule field activities. <br /> The wells will be abstKioned by a C57 licensed drilling company. The wells will be abandoned by <br /> filling the well casing and Sher pack with a neat cementlbentomte grout utilizing a pressure <br /> grouting tool. For protection of the seal at the land surface, after the grout level in the casing has <br /> stabilized, the well casing will be drilled out to a depth of two feet below ground surface. The <br /> subsequent 2-foot hole will be filled with concrete with `lamp black"to the ground surface to <br /> match the eristing pavement in order to restore the site to its original appearance. <br /> Upon completion of abandoning the well, Smith Environmental will prepare a brief letter report <br /> describing well abandonment activities. The letter will include request for closure certification of <br /> the site. <br /> w.W6731Vausalwp0V6.dw <br /> 1260 Graphics Thive Modesto,CA 95351-1502 (209)579-2221 Fax(209)579-2225 <br /> Engineering Consulting • Remediation • Construction <br />
