Do systems incorporating flexible liners (bladders) and vacuum monitor systems meet the technical requirements?
[March 19, 1992 letter from John Hendershot of World Enviro Systems] Answer: Flexible internally-fitted liner systems can be shown to meet the Federal requirements for release detection for both petroleum and hazardous substance USTs if certain conditions are met, including compatibility and automatic detection of a breach in either the outer tank or the inner liner. These systems cannot meet Federal requirements for upgrading or repairing existing UST systems. [July 9, 1992 letter to Mr. Hendershot (PDF) (4 pp, 18K)] Question 19: Please clarify whether the Federal underground storage tank regulations at 40 CFR 280.43 require inventory control with automatic tank gauges (ATGs). [October 2, 1992 letter from Mr. Durgin of Veeder Root to David Ziegele (PDF) (1 pg, 6K)] Answer: Inventory control is not required, regardless of the installation date, if the ATG has been shown to meet the performance standard and the probabilities of detection and of false alarm.
