Nr L�A The Plasteel Double Walled jacketed Type U tank was originally provided to H.J. Heinz by Perkins Welding and installed by Balch Petroleum in 1994. The sole use of the tank was to store 100% pure alcohol used for food processing. The tank was manufactured by Plasteel, Inc. of Escondido, California, including factory installation of Plasite 9060 lining material which is compatible with alcohol as well as the proposed storage of diesel fuel subsequent to re -certification. Please find attached copies of the tank description/quotation and interior lining data. We would propose the tank be inspected prior to removal and certified clean with no remaining product or vapor present. Due to the nature of alcohol with 100% evaporation we would hope the tank could be deemed "clean" and be made available to the owner to dispose of without any stigma of its prior use. If required, the tank could be inspected by a Certified Industrial Hygienist or Registered Marine Chemist to assure the condition of the tank. The site has ground water at approximately 10 feet below grade. In order to maintain control of the removal of the tank we propose the installation of clean ballast water (post certification) to insure its stability. The alternative would be to install a pump at the edge of the excavation to dewater during removal and backfilling. There is an access well at the edge of the tank. The water in the tank excavation could be sampled under your direction by a third parry state certified lab prior to excavation to prequalify it for pumping. Your direction regarding dewatering will be appreciated. The site is being re -developed into a business park. The current location of the tank is in an area dedicated for a proposed storm water drainage pond. The tank was installed with pea -gravel backfill in 1994. Our scope of work includes placing the existing pea gravel back into the excavation post-removal along with the clean overburden soil and Class H aggregate base rock after review of soil analysis and approval by your Department. Final construction/development of the retention pond will be subject to the approval of plans and specifications provided by others.
