Its of U.S. EPA Standard Ouation <br />Volumetric Tank Tightness Testing Method <br />This form tells whether the tank tightness testing method described below complies with <br />the performance requirements of the federal underground storage tank regulation. The <br />evaluation was conducted by the equipment manufacturer or a consultant to the <br />consultant to the manufacturer according to the U.S. EPA's "Standard Test Procedure for <br />Evaluating Leak Detection Methods: Volumetric Tank Tightness Testing Methods." The <br />full evaluation report also includes a form describing the method and a form summarizing <br />.� the test data. <br />i Tank owners using this leak detection system should keep this form on file to prove <br />compliance with the federal regulations. Tank owners should check with State and local <br />agencies to make sure this form satisfies their requirements. <br />) <br />Method Description <br />C <br />Name CEI 3000 Tank Level Module (TTT Rapid Test Mode) <br />Version Number TLP2 <br />Vendor Control Engineers, Inc <br />107 Menard Road <br />i (street address) <br />Houma LA 70361 (504) 872-4541 <br />(city) (state) (zip) (phone) <br />Evaluation <br />This method, which declares a tank to be leaking when the measured leak rate exceeds <br />the threshold of 0.95 gallon per hour, has a probability of false alarms [P(FA)) of 5 %. <br />The corresponding probability of detection [P(D)l of a 0.1 gallon per hour leak is 95.0%. <br />Therefore, this method ® does ® does not meet the federal performance standards <br />established by the U.S. Environmental Protection Agency (0.10 gallon per hour at P(D) <br />of 95% and P(FA) of 5%). <br />Test Conditions During Evaluation <br />The evaluation testing was conducted in a 10,000 gallon 0 steel ® fiberglass tank that <br />was 96 inches in diameter and 324 inches long. <br />The tests were conducted with the tank 95 percent full. <br />The temperature difference between product added to fill the tank and product already <br />in the tank ranged from -6.4 °F to7.4 °F, with a standard deviation of 4.3 °F. <br />The product used in the evaluation was No. 2, Diesel . <br />Volumetric TTT Method - Results Form Page 1 of 2 <br />
