SEMCO triple rinses underground <br /> p�trolaun tanks on site with a high-pressure Washing system. SEMCO adds biosolve detergent to <br /> its rinse water rendering the tanks clean.The underground petroleum tanks are given a tracking <br /> number at the site by the local regulatory oversight agency. Dry ice is then added to the tank(the <br /> amount of dry ice depends on size and type of product the rank held),an hour later the LEL is <br /> checked,and the tanks are loaded onto trucks. The underground petroleum tanks are then <br /> transported too and off-loaded at SEMCO's yard, located at 1217 S. Seventh St.io Modesto. <br /> At SEMCO's yard the tanks are off loaded from the truck and tested again for LEL. Before <br /> cutting 2'X 2' square holes in each end of the tank, SEMCO adds venturi ventilation to the tank <br /> and rechecks the LEL. If the reading is zero than the tank is cut. The"cut tanks"are then <br /> reloaded uuw the truck and shipped to Modesto Junk. Modesto Junk signs the tank tracking <br /> document and than recycles the tank as steel. SEMCO thea sends a oopy ofthe tank tracking <br /> document(as well as all other pettment information)to the local regulatory agency and the tank <br /> owner. <br /> SEMCO has been given permission by the Stanislaus County Fire Department to re-usc clean <br /> u�derground petroleum tanks for fire suppression storage[auks. SEMCO only muses tanks if it <br /> bhs permission to do so from the regulatory agency responsible for the tank. To this date no tanks <br /> fmm San Joaquin County have been re-used. If San Joaquin County has a policy for reuse of <br /> uIpderground petroleum storage tanks SEMCO would be interested in its requirements. 1 have <br /> included a copy of this letter for your files. <br /> '(frank you for your assistance ie processing this removal application.
