The Mine Safety and Health Administration (MSHA) requires mine operators to provide important safety and health protections to underground coal miners who work on and around diesel-powered equipment. The engines powering diesel equipment are potential contributors to fires and explosion hazards in the confined environment of an underground coal mine where combustible coal dust and explosive methane gas are present. Diesel equipment operating in underground coal mines also can pose serious health risks to miners from exposure to diesel exhaust emissions, including diesel particulates, oxides of nitrogen, and carbon monoxide. Diesel exhaust is a lung carcinogen in animals.
The information collection includes maintenance and use of diesel equipment; tests and maintenance of fire suppression systems on both the equipment and at fueling stations; and exhaust gas sampling.
The records are required to document that essential testing and maintenance of diesel- powered equipment are conducted regularly by qualified persons; that corrective actions are taken; and the persons performing the maintenance, repairs, examinations, and tests are trained and qualified to perform such tasks.
The safety requirements for diesel equipment include many of the proven features required in existing standards for electric-powered mobile equipment, such as cabs or canopies, methane monitors, brakes and lights. Sampling of diesel exhaust emissions is required to protect miners from overexposure to carbon monoxide and nitrogen dioxide contained in diesel exhaust.
Information collection requirements are found in: § 75.1901(a) Diesel fuel requirements; § 75.1911 (j) Fire suppression systems for diesel-powered equipment and fuel transportation units; § 75.1912 (i) Fire suppression systems for permanent underground diesel fuel storage facilities; §§ 75.1914(f)(1), (f)(2), (g)(5), (h)(1), and (h)(2) Maintenance of diesel-powered equipment; §§ 75.1915(b)(5), (c)(1), and (c)(2) Training and qualification of persons working on diesel-powered equipment.
The number of respondents increased due to a greater number of underground coal mines using diesel-powered equipment underground (from 213 mines to 223). The last approved collection included the hour and cost burden associated with the time to conduct training. It should have included only the cost of the recordkeeping associated with the training. This submission corrects the error. Because of this correction, the number of responses and hour burden decreased. The burden hour cost increased because the number of respondents increased.
Respondents: Increase of 10 (from 213 to 223)
Responses: Decrease of 11,249 (from 180,252 to 169,003)
Burden Hours: Decrease of 28,462 (from 42,826 to 14,364)
Cost of Burden Hours: Increase of $29,536 (from $428,272 to $457,808)
