The piping run south of the kitchen and main hospital should be abandoned. The boring map does not include the short underground section between the hospital buildings. The medical facility needs to maintain the above ground piping run within the building (will be cleaned and capped as part of the closure) for emergency purposes to fuel the boilers, as a secondary fuel source. From the basement at the main hospital building up the ten boilers on the roof top, the produce lines serve as emergency piping for the boilers. The piles will be valves and capped and mark for purpose. How will the unburied sections within the buildings be handled? Will they be rinsed and removed? How will the vertical section going to the roof be handled? At the southern terminus of piping underground into the main hospital building the pea gravel and backfill is at a level under the main white 18-inch water recirculation cooling pipe shown in the attached photo and therefore soil is not present below the product pipes which are above the 18-inch water recirculation cooling pipe. Pipes within the kitchen building will be emptied, cleaned (triple rinsed) and capped. AGE has reviewed with the facility operator and decided the following sampling is required. AGE recommend a soil sample collected through the wall to document the potential release from the product and return pipe. Two photos attached from within the main hospital basement. At the exit from the kitchen building (twenty feet north) the same sampling is proposed, through a hole in the concrete basement wall, a soil sample will be collected within native soil as best possible. The boring map does not include the short underground section between the hospital buildings. A cross section of the piping is very complex and a thorough review of the piping as built drawings and field inspections by the engineering staff during past emergency repairs demonstrate that the fuel pipe and return pipe are buried six to seven feet within a pea gravel bed, east of all other pipes and electrical lines. Within the road between the piping is north of the utility conduits and water pipes. Soil sample will be collected adjacent to the product piping run, as close as safely possible within a native soil at approximately eight to ten feet below surface grade. Results of the soil sample data will indicate a gross contamination release; However, no soil remediation within the piping run can be conducted with such a complex, sensitive piping network adjust to the product line which maintains a medical facility. Provide a cross-sectional drawing of the pipe. Include piping depth, boring angle, boring location relative to the pipe, depth of sampling under the pipe. The soil samples will be analyzed by EPA methods (8015-1.0 mg/kg/8260-0.005 mg/kg) with the lowest possible detection limits. Minimum detection limits of sample analysis. 1'll need a few more details to approve the St. Joseph's Hospital pipe closure-in-place permit. 17l also fax to Elite IV. 1. Written approval from Stockton Fire Dept allowing closure-in-place of the pipe. 2. The reason for requesting closure-in-place vs removal. 4. The boring map does not include the short underground section between the hospital buildings. 3. Provide a cross-sectional drawing of the pipe. Include piping depth, boring angle, boring location relative to the pipe, depth of sampling under the pipe. 2
