PHS/EHD has prepared the following comments <br /> for your consideration. <br /> The revised plan addresses only the petroleum hydrocarbon contamination and includes: <br /> cleaning of the concrete tank, disconnection of all piping and removal or closure in place <br /> with an inert matter, excavation of contaminated soil adjacent to the tank and further <br /> characterization of the residual impacted soil,backfilling the excavation, filling the concrete <br /> tank with sand and capping the entire site with an impermeable layer. The excavated soil <br /> will be treated on-site. <br /> PHS/EHD concurs with the recommendation to excavate contaminated soils adjacent to the <br /> tank to remove a potential threat of contamination to groundwater. PHS/EHD also concurs <br /> with the proposal to close the tank in place using sand, since at some time in the future it <br /> may be possible to excavate and remove the tank along with any residual soil contamination <br /> and due to the close proximity of the tank to the building. <br /> Prior to excavation and/or closure in place, the concrete tank will be cleaned and all rinsate <br /> properly drummed pending characterization and proper disposal selection. <br /> Soil samples will be collected from the excavation at 20 foot intervals or as deemed <br /> appropriate by PHS/EHD and analyzed for BTEX,TPH-gas, and TPH-D. Since chlorinated <br /> hydrocarbons have been evidenced in the area of the concrete tank, PHS/EHD further <br /> recommends that selected samples undergo chlorinated hydrocarbon analysis to further <br /> characterize documented chlorinated hydrocarbon contamination. <br /> 11 16-cry M of pages r <br /> Since the site is located within the Q post-It-brand fax transmittal memo 7671 2 <br /> require a backfill/grading permit.
