OT-5 was a 750,000-gallon concrete underground storage tank located between Sculpin and Tang Avenues in the southern portion of the Subase.The tank was one of nine tanks in the Site 23 Fuel Farm.The tank had a diameter of approximately 112 feet and was 11 feet deep.The top of the tank was about 5 feet below the ground surface.Results of a Subsurface Investigation 77 and 79 Alpine An intrusive field investigation was completed at the Pico Ski Club and Pico Administration buildings in Killington,Vermont on December 1,2010.This report includes the subsurface investigation results in response to a release of fuel oil from two underground storage tanks (UST) that were located at Pico Mountain within 500 feet of each other.
