					 the categories or subcategories defined in this subpart. Mines shall operate in
					 accordance with the applicable standards in this subpart to protect persons
					 against the hazards of methane gas and dust containing volatile matter. The
					 standards in this subpart apply to underground mines as well as surface mills
					 at Subcategory I-C mines. These mines are also required to be operated in
					 accordance with the other applicable health and safety standards published in
					 30 CFR part 57.

				  and subcategories are defined as follows:
(1)
				  Category I applies to mines that operate within a combustible ore body and
				  either liberate methane or have the potential to liberate methane based on the
				  history of the mine or the geological area in which the mine is located.
				  Category I is divided into Subcategories I-A, I-B, and I-C as follows:
(i) Subcategory I-A applies to mines that
				  operate within a combustible ore body and liberate methane and in which-
(A)A concentration of 0.25 percent or more
				  methane has been detected in the mine atmosphere and confirmed by laboratory
				  analysis; or
(B) An ignition of
				  methane has occurred.
