1 <br />0 <br />Results of the Performance Evaluation <br />sConducted According; to EPA Test Procedures <br />Pipeline Leak Detection System <br />Used as an <br />Hourly Test <br />L-1 <br />Ii <br />L' <br />J <br />u <br />0 <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 Svstems. The full <br />evaluation report includes seven attachments. <br />Tank 'system owners who use this pipeline leak detection system should keepthis form on <br />rile 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: Line Leak Detector <br />Version of System: Model LLP2 <br />Manufacturer Name: Control Engineers, Inc. <br />114 Menard Road, P.O. Box 9037 <br />(street address) <br />llouma, LA 70360 <br />(city, state, zip code) <br />(504) 872-4541 <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 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 1.0 psi in this evaluation is 100 %. <br />Pipeline Leak Detection System - Results Form <br />Page 1 of 5 <br />
