Mdy 4, 1994,-.San Joaquin County Public Health Seip ices, En.vironmentai Health" <br /> Division <br /> (SJCPHS,EHD)approved the April 8, 1994,`soil investigation work plan prepared. by.;Condor.Earth . <br /> Technologies, Inc. (Condor);-for Idlewild Market. The approved \York plan proposed drilling two <br /> vertical soil borings and one angle boring to assess the extent of.soil contamination along the north t,; <br /> sidewall of Pit I-..The-proposed soil bori;;g'locations are shown in Figure I, attached, which is a <br /> duplicate of Figure 3 in the work:plan.'r--- = <br /> Ori August 15, 1994, Condor monitored the installation of two angle borings;at Idlewiid 2 <br /> Market. Two angle borings were installed in leu of two vertical acid one angle boring due to access <br /> limitations at the site. Unfortunately, the two angle borings were installed without SJCPHS,> HD <br /> " oversight,-and are therefore--not-r valid:by-S?.CPHc;FHD:-You stated.in:yourPDecember } <br /> 8a 1994, letter to George Gemellos "T}ie-work as proposed in the approved work plan should be <br /> rescheduled by January 16,, 1995." This letter is to update SJCPHS;EHD of the current site conditions <br /> at idlewild Markel and request your approval to modify the'April 8, 1994, work plan as described <br /> below. <br /> Presently, Pit Fis-backiiied with pea gravel-to-a depth of approximately two feet below grade, <br /> thereby preventing a drill rig access to the proposed locafion of SB-2, as shown in the attached Figure <br /> 3. This was also the case on August 151 1994, when two angle borings were installed at the site. <br /> Therefore, rather than backfilling-Pit 1 to access the proposed location of SB-2, Candor recommends <br /> the following amendments to the-approved work plan; <br /> • —Installation of up to five angle borin2s, SB-I' through SB.5; at locations and angles showrk 111 <br /> .. <br /> Figure 2, attached, in leu of the two vertical .and one angle boring proposed in',the April 8,7- <br /> - 1994,-work-plan, and <br /> ENVIRONMENTAL • 4 GEOLOGICAL- • ENGINEERING. _ GEOTECHNICAL <br />
