Atmospheric tracer investigation of fugitive-emissions transport in the Colorado oil shale region

OSTI ID:5151546
Atmospheric tracer experiments were conducted in July 1981 to investigate transport and dispersion of fugitive emissions in the complex terrain near the federal oil shale lease Tract C-e in Colorado. In anticipation that spent-shale disposal areas could become prime fugitive emissions sources, the atmospheric tracer gas SF/sub 6/ was released from a proposed spent shale disposal area. The SF/sub 6/ tracer gas release rate was 26 kg/h. The tracer release height was near respiration height (about 1.5 m). Airborne SF/sub 6/ tracer gas concentrations were sampled at 32 radio-controlled bag-sampling stations (15 minute sampling times) and along roads with syringe grab-samplers. Sampling sites were from 0.6 to 13-km from the tracer-gas release site. There were four experimental time periods for releasing and sampling tracer gas, two evening and two morning time periods. Results include information on the following: a time-history of pollutant concentration changes upwind and in gulches before, during, and after sunrise; identification of major transport flow paths in the evening and morning; and pollutant mixing and channeling in valleys and downwind of valley confluences.
