This evaluation of fugitive dust air pollution from mining operations identifies and compiles currently available information on emission sources and rates, regulatory approaches, control techniques, measuring and monitoring techniques, health and welfare effects, and research programs related to mining activities. The assembled information serves as a basis for the design of near-term research and development programs that might be implemented by the Environmental Protection Agency. The scope of the study includes both surface and underground mining plus related operations normally performed at the mine sites, such as crushing and storage. Nearly all particulate emissions at mines are categorized as fugitive dust because they generally are emitted at ground level as a result of equipment activity or material transfer rather than from stacks.
