File No. 1677-1 <br />23 April 1985 <br />1:11 AIPERSON GEOTECHNICAL CONSULTANTS, INC. <br />fir,csavirm <br />Mr. John Walker <br />PacTel Mobile Access <br />151 Kalmus Drive, Building C <br />Costa Mesa, California 92626 <br />Subject: PacTel Mobile Access Antenna <br />Stockton - Site B <br />Manthey Road <br />Stockton, California <br />Dear Mr. Walker: <br />In response to our phone conversation of 9 April 1985, contained <br />herein is a brief summary of the soil conditions that we <br />encountered while conducting a soil investigation at the Stockton <br />Site B on 5 April 1985. The site is located south of Stockton <br />(see Figure 1) near the intersection of Wolfe Road and Manthey <br />Road in San Joaquin County, California. <br />Upon initial arrival on the site on 5 April 1985, we noted that <br />the surface soil was white, loose, and dry; almost a powdery <br />dust. After drilling approximately two feet, a sample was taken <br />and a piece of asbestos pipe was retrieved in the sampler. At <br />this point, we realized that the site was probably located on an <br />old landfill that consisted of asbestos debris, including pieces <br />of asbestos pipe. The areal extent of the asbestos fill was <br />estimated to be approximately three acres. The PacTel lease area <br />is completely within this fill (see Figure 2). The vertical <br />extent of the asbestos at the site is approximately three feet as <br />determined by our test boring and other shallow hand <br />excavations. The Geotechnical Engineer at the site decided to <br />continue drilling on the outside chance that the site might still <br />be used for the mobile access antenna. A log of the boring is <br />attached as Figure 3. <br />On 9 April 1985 authorization was received by Mr. Walker to test <br />the surface material at the site for asbestos content. A sample <br />of this material was sent to EAL Corporation in Richmond, <br />California and checked for asbestos and other fibers. The <br />results, obtained on 15 April 1985, indicated the material to <br />consist of 10% to 20% asbestos (chrysotile), and 80% to 90% <br />calcite. <br />Mailing Address: PA Box 420878 Sacramento.
