5 . 0 Test Results and Discussion The test results reported by the Pneumercator LLP -203 Series PLLD were compared to the leak conditions induced in the line . Forty-five hourly tests were conducted using the procedures described in Section 2 . 0 of this report . For the hourly testing 22 of these tests were run with a 3 gal/ h leak induced in the line and 23 were run with the line in the tight condition and 3 of these tests were performed with vapor in the line . During all of the hourly testing , the system reported no failures with the line in the tight condition and detected ( reported fail ) a leak for all of the tests on the line with a leak induced . This reported leak or passing test by the Pneumercator console was compared to the induced leak or no leak and the results are reported in Appendix B . Testing was conducted using procedures specified in the US EPA protocol . For the hourly testing , the results of the evaluation have been calculated using Section 5 . 2 of the US EPA procedures for systems that do not report a leak rate . The results of the data analysis have been summarized in Table 3 . The pipeline configuration is described more completely using the EPA Pipeline Protocol Attachment 3 reported as Table 3 . The test data for this evaluation are contained in Attachment 4 and 5 and 6 , which correspond to Attachments 4 , 5 and 6 of the US EPA Protocol . Calculation of PFA and Po Since the Pneumercator LLP -203 Series PLLD hourly tests are a pass/fail system , the calculation of the Probability of Detection ( PD) and the Probability of False Alarm ( PFA) was based on the number of correct test results compared to the number of tests of that type . For these standards , the statistics for estimating PFA and Po were based on the calculations found in Section 5 . 21 and 5 . 22 of the pipeline protocol . Performance for Hourly (3 . 0 gal/hr) Testing A total of 45 tests (23 tight and 22 with induced leaks) were conducted for the system . A total of 3 tests (2 tight and 1 with an induced leak) with trapped vapor were conducted for the system . There were no missed detections or false alarms observed for these 45 tests . Forty-five tests were conducted on the system including the three tests with trapped vapor. The Po and PFA were calculated by dividing the number of correct results by the total number of such tests that were conducted . Since there were no false alarms or missed detections using the hourly test , the estimated PFA was 0 % and the estimated Po was 100 % . Since one cannot assume that a qualitative method would never make a mistake only based on about 45 tests , a 95 % confidence limit was calculated for each parameter . Based on these calculations , one can be 95 % confident that the PFA is between 0 % and 12 . 73 % , while the 95 % confidence limit for Po is from 87 . 79 % to 100 % . All of the test times were 13 minutes or less . 5
