Following removal of the ASTs, Hudspeth began excavation activities of the fill material surrounding the underground fuel piping. The excavated fill material was stockpiled adjacent to the piping excavation pending analysis and removal.The underground fuel piping and fuel dispensers were placed into a storage bin pending removal. The piping, fuel dispensers, and soil were transported for disposal under manifest number 022071064JJK to Hazmat TSDF, Inc. in Bloomington, California on March 12, 2021. A copy of the hazardous waste disposal manifest is included in Appendix D. 2.2 Soil Sampling Activities On February 24, 2021, following removal of the ASTs, underground piping, and fuel dispensers, APTIM personnel collected four soil samples, labeled DS-1(1), DS-2(1), PL-1(1) and SP-1,2,3,4, from below the former fuel dispensers, piping trench,and soil stock pile under the direction and supervision of Mr. Daniel Stowe with the SSJFA. Soil samples DS-1(1) and DS-2(1) were collected from the piping trench below the location of the former fuel dispensers.The soil samples were collected at a depth of three feet below surface grade using a hand auger and steel sleeves. Soil sample PL-1(1)was collected from the center of the piping trench.The soil samples were collected at a depth of three feet below surface grade using a hand auger and steel sleeves. In order to evaluate soil re-use or disposal options, one 4-point composite soil sample, labeled SP-1,2,3,4, was collected from the soil stockpile located east of the former piping trench. The soil sample was collected by pushing sample container into the stockpile at random locations until each was full. After the soil samples were collected,the samples were appropriately labeled, placed in a cooler with ice, and transported under chain-of-custody protocol to the analytical laboratory. Copies of the chain of custodies are included in Appendix F. 2.3 Sample Analyses The soil samples were transported and submitted to McCampbell Analytical, Inc. (McCampbell), an ELAP- certified laboratory in Pittsburg, California. All samples were analyzed for total petroleum hydrocarbons as diesel (TPH-D) by EPA method 8015B, total petroleum hydrocarbons as gasoline (TPH-G), and volatile organic compounds (VOCs) by EPA Method 8260B. 2.4 Soil Sample Analytical Results Analysis of the stockpile sample SP-1,2,3,4 detected TPH-D and TPH-G at concentrations of 630 and 110 milligrams per kilogram (mg/kg), respectively. Analysis of VOCs detected n-Butyl benzene at a concentration of 0.75 mg/kg; 1,2,4-Trimethylbenzene at a concentration of 1.4 mg/kg; 1,3,5- Trim ethyl benzene at a concentration of 0.35 mg/kg; m,p-Xylene at a concentration of 0.12 mg/kg; and Total Xylenes at a concentration of 0.12 mg/kg. No other analytes were detected in any of the remaining soil samples collected below the former fuel dispenser locations or within the piping trench.
