(Treadwell & <br /> Rollo) on April 19, 2005, at 130 North Hunter Street, Stockton, California. By email dated May <br /> 13 , 2005 , Treadwell and Rollo provided laboratory results for samples collected from an _ <br /> approximately 170 cubic yard soil stockpile generated during the installation of caissons at the <br /> above-referenced site, and a calculation of the mass of the total petroleum hydrocarbons (TPH) in <br /> the stockpile. Treadwell and Rollo has requested EHD's concurrence to leave the stockpiled soil <br /> onsite. <br /> EHD approves the use of the stockpile soil to build the base of a ramp for the parking garage <br /> currently being constructed at this site. This decision is based on the following information: <br /> • Benzene, toluene, ethyl benzene, total xylenes, and TPH-motor oil were not detected in <br /> either soil sample. <br /> • TPH-kerosene and TPH-gasoline were detected at low concentrations in soil samples <br /> SPA-1 at 4.7 milligrams per kilogram (mg/kg) and 57 mg/kg, respectively; and SPA-4 at <br /> 5 .4 mg/kg and 1 .9 mg/kg, respectively. <br /> Treadwell and Rollo calculated the stockpile total TPH to be approximately 17.6 pounds . <br /> • The stockpile soil will be placed above the ground surface and encapsulated in concrete. <br /> Should you have any questions or concerns regarding this letter, please contact Vicki McCartney <br /> by mail (address on letter head), by telephone at (209) 468-3456, or by email at <br /> vmccartney@sj cehd.com. <br /> Donna Heran, RENS, Director <br /> Environmental Health Department <br /> Victoria L.
