While employed at another consulting firm, Mr. Cook directed a staff of engineers and geologists for the removal of a 2,000-gallon gasoline underground storage tank (UST), consistent with the requirements of Chapter 62-761 FAC. Services included the following:
- Performed permitting, prepared subcontract agreements and bid documents, and solicited bids from qualified Pollutant Storage System Specialty Contractors (PSSSC) to perform excavation of soil, extraction of UST, decommissioning, cleaning, removal and disposal of the petroleum storage system.
- Provided project management, field inspection and supervision, scheduling/coordination and technical support during removal, decommissioning, cleaning, and disposal of petroleum systems, sludges and liquid contents. Activities were photo documented to have a record of the condition of the UST and associated piping at the time the equipment was removed.
- Assessed the quality of soils surrounding and under the UST by collecting soil samples and performing headspace screening during the excavation process using an OVA-FID. Soil samples were obtained from the walls and bottom of the excavation to check for the presence of petroleum compounds which may have leaked from the UST or ancillary piping.
- Evaluated physical conditions surrounding the tank and piping excavations for petroleum hydrocarbon constituents as required by applicable state guidelines.
- Prepared a tank closure assessment report (TCAR) documenting tank closure activities and associated environmental sampling tasks. The TCAR included a discussion of the UST removal actions, headspace screening and soil confirmatory sampling, groundwater sampling and conclusions and recommendations. Maps were also provided to illustrate the soil and groundwater sampling activities, the location of the former UST and closure sampling actions. Approval of the TCAR was obtained on October 8, 2004.
