Results of the Performance Evaluation <br /> Conducted According to EPA Test Procedures <br /> Pipeline Leak Detection System <br /> Used as a <br /> Line Tightness 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 for <br /> conducting a line tightness 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 state <br /> and local agencies to make sure this form satisfies the requirements of these agencies. <br /> System Evaluated <br /> System Name: PLC-5000 Site Controller with Automatic Electronic Line Leak Detection and <br /> the 98 LD-2000 and 98 LD-2000 PLC Mechanical Line Leak Detectors <br /> Version of System: <br /> 8700 East Long Mesa Drive <br /> (street address) <br /> Prescott Valley AZ 86314 <br /> (city,state,zip code) <br /> (800) 367-0185 <br /> (telephone number) <br /> Evaluation Results <br /> 1. The performance of this system <br /> (X) meets or exceeds <br /> ( ) does not meet <br /> the federal standards established by the EPA regulation for line tightness tests. <br /> The EPA regulation for a Line Tightness test requires that the system be capable of detecting a <br /> leak as small as 0.1 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 0.1 <br /> gal/h defined at a pipeline pressure of 30 psi in this evaluation is 100 %. <br /> Pipeline Leak Detection System-Results Form Pagel of 5 <br />
