(a)
methane emissions from all ventilation shafts in use by the mine operator;
(b)
methane emissions from drainage stations and from the methane drainage system, whether occurring as a result of intentional or unintentional venting, or incomplete combustion from flaring;
(c)
methane emissions occurring during post-mining activities and within the area of the coal mine.
3. Methane emissions resulting from active surface coal mines include the following emissions:
(a)
methane emissions occurring at the coal mine during the mining process;
(b)
