"Sul WTC-7 (dove i fenomeni subiti dall'acciaio sono documentati anche altrove) c'è stato il discorso degli incendi dei depositi di nafta che conteneva.E di quelli stava parlando Barnett."
(John l'" esperto")

Engineers from the New York State Department of Environmental Conservation investigated oil contamination in the debris of WTC 7. Their principal interest was directed to the various oils involved in the Con Ed equipment. However, they reported the following findings on fuel oil: "In addition to Con Ed's oil, there was a maximum loss of 12,000 gallons of diesel from two underground storage tanks registered as 7WTC." To date, the NY State Environmental Protection Agency (EPA) and DEC have recovered approximately 20,000 gallons from the other two intact 11,600-gallon underground fuel oil storage tanks at WTC 7. It is worth emphasizing that 20,000 gallons (of a maximum of 23,200 gallons) where recovered intact from the two 12,000-gallon Silverstein tanks. So, it is probable that the 20,000 gallons recovered was all of the oil in the tanks at that time. Since the oil in the Silverstein tanks survived, we can surmise that there was no fire on the ground floor. Note that the size of a 12,000 gallon tank would be a little less than 12 feet by 12 feet by 12 feet (if built as a cube). Based on the listings in Table 5.2, it is probable that the 20,000 gallons that were recovered were from the Silverstein Properties' emergency power system. The data obtained from Silverstein indicate that the pumping rate from their tanks was 4.4 gpm. If the Silverstein pump had started pumping at 10 a.m., when Con Ed shut down power to the building immediately following the collapse of WTC 2, and continued pumping until the collapse of WTC 7 at 5:20 p.m., less than 2,000 gallons would have been used. The residual 20,000 gallons found in the two 12,000-gallon tanks, therefore, can not be used as an indicator of whether or not the Silverstein generator sets were on line and running. Similarly, the SSB pump, which had a pumping rate of 75 gpm, would have drained the two 6,000 gallon tanks serving that system in less than 3 hours. This could have accounted for the lost 12,000 gallons reported by EPA or the tanks could have been ruptured and the oil spilled into the debris pile. This is very dishonest. The figure of 12,000 gallons was the maximum quantity of fuel oil that could possibly be missing. This figure would include, for example, the difference between the actual quantity of fuel oil in the tanks at the time (which would not necessarily be known) and the maximum quantity that the tanks could hold. Consequently, this estimate of 12,000 gallons would include a provision for fuel oil that never existed.
