Atmospheric tracer release techniques have been usedto quantify low-level fugitive methane emissions fromcomponents and facilities in all sectors of the naturalgassystem in the United States. The emission data arecollectedas part of a program to extrapolate the emissions fromthe entire U.S. natural gas industry and thus reduceuncertainties in the environmental impact of increasednatural gas use. In these experiments, the totalmethaneemission from a site is measured by releasing a tracergas (SF6) at the natural gas facility to simulate thesource.Both methane and tracer levels are measured with real-time instruments deployed in a mobile laboratory downwindof the site. A large range of emission levels for thedifferent sectors of the entire system was determined.Withinany one group of a particular facility type there is alsomuch variability in the emission rates. The exact natureandnumber of gas system components in a facility areimportantfactors in determining its emission level.
