Report emissions from both the combustion of collected coal mine CH4 and any other fuels.(f) An underground coal mine that is subject to this part because emissions from source categories described in Tables A-3, A-4 or A-5 of subpart A of this part, or from stationary combustion (subpart C of this part), is not required to report emissions under this subpart unless the coal mine liberates 36,500,000 actual cubic feet (acf) or more of methane per year from its ventilation system. 75 FR 39763 , July 12, 2010, as amended at 76 FR 73901 , Nov. 29, 2011; 78 FR 71966 , Nov. 29, 2013
