The following sections describe the <br /> proposed scope of work. <br /> Health and Safety, and Underground Utility_Locating <br /> Prior to performing any work, APTIM will prepare a site-specific Health and Safety Plan <br /> (HASP) detailing appropriate precautions to take to safely remove the AST system.

It is estimated that 3,000-gallons of fuel remain in the tanks. The diesel <br /> fuel may be able to be sold for re-use by a local excavating company or will be disposed of as <br /> non-hazardous waste, or a combination of the two options. Once the fuel is removed, the ASTs <br /> and accessible piping will be rinsed. Diesellrinseate generated during this process will be <br /> properly transported to and disposed of at a selected disposal facility as non-RCRA hazardous T <br /> waste. <br /> After rinsing, dry ice will be added into the interior of the ASTs at a rate of 20 pounds per 1,000- a <br /> gallons of capacity(200 pounds total). The percent oxygen and lower explosive 1Lwill T <br /> then be measured to ensure both are below 10%. 02/02/2021'*f4rl <br /> T <br /> [?evefo��itien�Se.vices C <br /> AST Removal and Disposal ,;,ii{��� <br /> After the tanks have been rinsed and certified as non-hazardous,APTIM's licensed vendor C <br /> Hudspeth Environmental Remediation and Construction Services(Hudspeth) will disconnect the C <br /> COM20-0379 PC-1 � <br />
