What are the sources of pollution which may be affecting air quality here?
There are several potential sources of air pollution in southern Idaho which may affect air quality at Craters of the Moon. The Idaho National Engineering Laboratory, a Department of Energy nuclear research center employing more than 10,000 people, lies 15 miles from the monument. High level radioactive waste that contains acids is heated to convert the waste from liquid to solid. The acids are burned off and nitrogen oxides are released in a yellowish plume through a tall stack – 725 tons in 1988. In addition to the nitrogen oxides, visibility impacts and release of airborne radioactivity are potential concerns. Two large mineral and chemical plants are located in the Pocatello area, 60 miles southeast of the monument. In addition to general industrial air pollution, the fluorides emitted as a result of fertilizer production are a potential threat. Mining practices and agricultural activities also degrade air quality. Burning stubble off fields is a common practice, and the dust gener
