(A) "Alternate operating procedure" means any procedure relating to the operation or usage of underground diesel equipment not specifically authorized in this chapter that the chief determines will not cause an unsafe condition.
(B) "Alternative technology" means any technology relating to the operation or usage of underground diesel equipment not specifically authorized in this chapter that the chief determines will not cause an unsafe condition.
(C) "Authorized representative of miners" means a member of a mine health and safety committee elected by miners at a mine, an individual employed by an employee organization representing miners at a mine, or an individual authorized as the representative of miners of a mine in accordance with MSHA regulations 30 C.F.R.

(D) "Attended" means a diesel equipment operator is within sight or sound of the diesel-powered equipment while it is in operation.
(E) "Diesel fuel tank" means a closed metal vessel specifically designed for the storage or transport of diesel fuel.
(F) "Diesel fuel transportation unit" means a self-propelled or portable wheeled vehicle used to transport a diesel fuel tank.
(G) "Diesel engine" means any compression ignition internal combustion engine using the basic diesel cycle where combustion results from the spraying of fuel into air heated by compression.
(H) "Diesel-powered equipment package" means a diesel engine with an intake system, exhaust system, and a safety shutdown system installed that meets the specific MSHA permissibility requirements for diesel-powered equipment packages intended for use in underground coal mines.
(I) "Diesel technical advisory committee" and "technical advisory committee" mean the two-member group appointed by the chief pursuant to rule 1501:10-2-27 of the Administrative Code to provide the chief with technical advice and recommendations concerning the technical operating aspects of underground diesel-powered equipment, including, but not limited to, responses to requests for a change or variance from any technical requirement in this chapter, or the use of an alternate operating procedure, alternative technology, major operational change, or new technology.
(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.
(O) "New underground diesel technology" and "new technology" mean an advance in diesel technology that is developed for safe application in underground coal mines after the effective date of this rule.
(P) "Long-term underground diesel fuel storage facility" means a facility that is designed and constructed to remain at one location for the storage or dispensing of diesel fuel and which does not move as mining progresses and which has been installed in full compliance with all applicable safety guidelines and procedures for an underground fuel storage facility as provided in rule 1501:10-2-08 of the Administrative Code.
