June 3, 1989 Guidance on Limiting Potential to Emit in New Source Permitting 2.31

Fugitive emissions may or may not be included in determining the potential to emit for a surface coal mine and coal preparation facility. The two facilities are considered one source. The main activity at the site is the coal mine and in determining PSD applicability, the source would be considered a surface coal mine. Therefore, fugitive emissions would generally not be counted in the sources potential to emit.

Fugitive emissions are only to be considered from sources regulated as of 8/7/80 under 40 CFR Part 60 and 61 and source categories liked under 52.21 (i)(4)(vii). The mine's potential emissions would therefore include non-fugitive mine emissions and all emissions from the coal preparation plant. If potential emissions exceed 250 tons/yr. the mine is subject to PSD review and BACT would then be applied to all emissions, both fugitive and non-fugitive, for the entire operation.
