Results of the Performance Evaluation <br /> Conducted According; to EPA Test Procedures <br /> Pipeline Leak Detection System <br /> Used as an <br /> Hourly Test <br /> This form summarizes the results of an evaluation to determine whether the pipeline leak <br /> detection system named below and described in Attachment 1 complies with federal regulations <br /> for conducting an hourly test. The evaluation was conducted according to the United States <br /> Environmental Protection Agency's (EPA's) evaluation procedure, specified in Standard Test <br /> Procedures for Evaluating Leak Detection Methods:Pipeline Leak Detection Systems. The full <br /> evaluation report includes seven attachments. <br /> Tank'system owners who use this pipeline leak detection system should keep this form on <br /> file to show compliance with the federal regulations. Tank system owners should check with <br /> state and local agencies to make sure this form satisfies the requirements of these agencies. <br /> System Evaluated <br /> System Name: TLS Pressurized Line Leak Detector, Series 8484 <br /> Version of System: ---- <br /> Manufacturer Name: Veeder—Root <br /> 125 Pamder Forest DriYe, P.O. Box 2003 <br /> (street address) <br /> Simsbury, CT 06070-2003 <br /> (city,state,zip code) <br /> (203) 651-2700 <br /> (telephone number) <br /> Evaluation Results <br /> 1. The performance of this system <br /> A meets or exceeds <br /> ( ) does not tneet <br /> the federal standards established by the EPA regulation for hourly tests. <br /> The EPA regulation for an hourly test requires that the system be capable of detecting a leak <br /> as small as 3.0 gal/h with a probability of detection(PD) of 95% and a probability of false <br /> alarm (PFA) of 5%. <br /> 2. The estimated PFA in this evaluation is 0 % and the estimated PD against a leak rate of <br /> 3.0 gal/h defined at a pipeline pressure of 20 psi in this evaluation is 100 qo, <br /> ® Pipeline Leak Detection System-Results Fount Page I of 5 <br />
