----- FUGITIVE EMISSIONS AND FUGITIVE DUST EMISSIONS Introduction and Purpose This stone has been prepared to define the differences between, and discuss pertinent facts concerning two separate, but in some cases, strikingly similar air pollution problems, i.e., fugitive emissions and fugitive dust emissions.
AIR QUALITY CALCULATIONS Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may Emission Point Number of Equipment Uncontrolled Emission Factor (lbs/ton of material) Controlled
Emission standards are typically applied only to point source industrial emissions, and not to fugitive sources such as open pit mining or tailings dams, other than to specify that all reasonable and practical measures need to be taken. The modern era of air quality management, which is emanating largely out of

DEPARTMENT OF ENVIRONMENTAL CONSERVATION AIR QUALITY CONTROL MINOR PERMIT Permit No.: AQ0978MSS01 Date: Preliminary October 19, 2006 The Alaska Department of Environmental Conservation (Department), under the authority of AS 46.14 and 18 AAC 50, issues Air Quality Control Minor Permit No. AQ0978MSS01 to the permittee listed below.
Table 1 lists the fugitive emission sources identified in the Title V permit, briefly describes the measures and practices employed to control fugitive emissions at each source and identifies the fugitive emission sources that require visible emission observation. These sources are further described below. 3.1
NIOSH Mining's Pittsburgh site occupies 180 acres and serves as one of two focal points for federal mine safety and health research. The basis for the research is surveillance data and stakeholder input and the program addresses most mining sectors.
