Criterion for Declaring a Leak <br /> 3 . This method <br /> _uses a preset threshold <br /> _ measures and reports the output quantity and compares it to a predetermined threshold to <br /> determine whether the pipeline is leaking. <br /> X Other _The system utilizes pressure decay over time after pump shutdown . Two methods of <br /> operation are available, test only after pump shutdown, or test after pump shutdown or hourlyif f no <br /> activity. Three methods of baseline calibration are provided, MANUAL, CALCULATED and AUTO <br /> CAPTURE (TMS4000 series only) . MANUAL and AUTO CAPTURE require a 3gph leak generating <br /> device, where time is entered manually (MANUAL), or measured and automatically captured (AUTO <br /> CAPTURE) by the system . The CALCULATED method requires the manual entry of three parameters , <br /> Line Volume, Charge Pressure and Bulk Modulus . Pump shutdown on leak detect is programmable, but <br /> not required . <br /> 4 . This method <br /> X uses a single test <br /> _ uses a multiple-test sequence consisting of tests (specify number of tests required) <br /> separated by hours (specify the time interval between tests) to determine whether the <br /> pipeline is leaking. <br /> 5 . This method declares a leak if the output of the measurement method exceeds a threshold of <br /> 1 . 8 gallon per hour (specify flow rate in gal/hr) in 1 out of 1 tests (specify, for example, 1 out of <br /> 2 , 2 out of 3) . Please give additional details , if necessary, in the spaceprovided . <br /> Evaluation Approach <br /> 6 . A total of 23 tests were conducted on non-leakingtank(s) between 11 / 12/2020 (date) and <br /> 12/4/2020 (date) . A description of the pipeline configuration used in the evaluation is given in <br /> Attachment 3 . <br /> T The pipeline used in the evaluation was between 1 . 5 and 4 in. in diameter, 2533ft long and constructed <br /> of rigid(FRP), semi-rigid and flex (fiberglass, steel , or other) . <br /> 8 . A mechanical line leak detector <br /> was <br /> X was not present in the pipeline system . <br /> 9 . The evaluation was conducted on 1 (how many) pipeline systems ranging in diameter from <br /> 1 . 5 in. to 4 in. , ranging in length from 2533 ft to 2533 ft, and <br /> constructed of rigid(FRP), semi -rigid and flex (specify materials) . <br /> 10 .
