Date: December 17,2007 Praxair Services,Inc.QA . <br /> Revised by: Randy Golding Tracer TighrX <br /> Approved by:Randy Golding Version 6 <br /> has displaced the entire volume of the vent piping. The concentration of the tracer in the receiving container is then <br /> measured. <br /> Leak Simulation <br /> Injecting a tracer into the backfill performs a leak simulation. The leak simulation tracer is not one of the tracers used in <br /> testing the system. The migration period of the leak simulation tracer is monitored through the sampling probes. The <br /> minimum migration time required for the test is equal to the time required for the leak simulation tracer to move an <br /> acceptable distance. The minimal acceptable distance is the longest distance that the test tracer would have to travel from <br /> any leak location to the location of a sampling probe. <br /> Sample Collection <br /> Once the leak simulation migration period is determined,the inoculation and waiting period is completed and sampling <br /> can begin.Vapor samples are collected from all sampling probes. Additional vapor samples may be collected from sumps <br /> containing UST components, under dispenser containers (UDCs) and from the interstitial spaces of double walled <br /> components. <br /> Sample Analysis <br /> Samples are analyzed using an on site laboratory grade gas chromatograph(GC). The GC is calibrated using an external <br /> gas standard. Samples are analyzed by direct injection into the GC. The results are evaluated by comparison to the <br /> analytical standard. Whenever tracer is detected in the subsurface samples,blanks are ran to validate the tracer detection. <br /> Spill-Bucket Testing <br /> Over-spill-buckets are tested hydro-statically. A decrease in water level indicates a leak. If leaks occur,spill bucket seals <br /> should be repaired or replaced. <br /> Reporting <br /> The findings of the Tracer Tight®ELD test and site evaluation will be summarized in a written report and sent to the client <br /> within two weeks of the completion of the fieldwork. All data acquired from probe and sump samples will be reported <br /> along with spill bucket hydro-test results. <br /> THISINFORMATIONIS THE PROPERTY OFPRAXAIR SERVICES INC.. <br /> 3 of 3 <br />
