(J) "Exhaust emission" means any substance emitted to the atmosphere from the exhaust port of the combustion chamber of a diesel engine including exhaust gas and particulates.
(K) "Exhaust emissions control and conditioning system" means a device or combination of devices that will collect and treat diesel exhaust emissions at the exhaust port of the engine, and will reduce the volume of, or eliminate emissions of, diesel particulate matter, carbon monoxide and oxides of nitrogen in accordance with the requirements and standards of 30 C.F.R. Part 7.
(L) "Fuel injection system" means the fuel delivery system to the motor.
(M) "Major operational change in underground diesel-powered equipment usage" and "major operational change" mean a use of underground diesel-powered equipment that the chief has determined, upon review by and recommendation from the technical advisory committee, deviates significantly from the rules and procedures established in this chapter.
