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. This 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. 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. 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: section 75.1901(a), Diesel fuel requirements; section
75.1904(b)(4)(i), Underground diesel fuel tanks and safety cans;
Section 75.1906(d), Transport of diesel fuel; section 75.1911(j),
Fire suppression systems for diesel-powered equipment and fuel
transportation units; section 75.1912(i), Fire suppression systems
for permanent underground diesel fuel storage facilities; sections
75.1914(f)(2), (g), (h)(1), and (h)(2), Maintenance of
diesel-powered equipment; sections 75.1915(b)(5), (c)(1), and
(c)(2), Training and qualification of persons working on
diesel-powered equipment.

The number of respondents
decreased due to a reduction in the total number of active
underground coal mines which includes a reduction the number of
active mines using diesel-powered equipment (from 223 mines to
151). The number of affected mines and the total pieces of
diesel-powered equipment have decreased, but large mines are using
more heavy duty and permissible diesel-powered equipment. The
increase in the number of pieces of heavy duty and permissible
diesel-powered equipment, which require weekly exhaust testing,
results in an overall increase in the number of annual responses,
and burden hours show a slight increase as well. Respondents:
Decrease of 72 (from 223 to 151) Responses: Increase of 8,656 (from
169,003 to 177,659) Burden Hours: Increase of 58 (from 14,364 to
14,422) Cost: Decrease of $135,184 (from $457,808 to $322,624)
