West Virginia Code Chapter 22A. Miners' Health, Safety and Training § 22A-2A-601. Specifications for fuel

(a) The director shall establish standards for fuel to be used in diesel-powered equipment in underground coal mines. A purpose of these standards is to require the use of low volatile fuels that will lower diesel engine gaseous and particulate emissions and will reduce equipment maintenance by limiting the amount of sulfur in the fuel. Another purpose of the standards for fuel is to reduce the risk of fire in underground mines by establishing a minimum flash point for the diesel fuel used.

(b) Each coal mine using diesel equipment underground shall establish a quality control plan for assuring that the diesel fuel used complies with the standards established pursuant to this section. The director shall also establish a procedure under which each mine operator will provide evidence that the diesel fuel used in diesel-powered equipment underground meets the standards for fuel established by the commission.
