Under Section 101(a) of the Federal
Mine Safety and Health Act of 1977 (Mine Act), and Title 5, United
States Code, Section 553, the Secretary of Labor shall develop,
promulgate, and revise as may be appropriate, improved mandatory
health or safety standards for the protection of life and
prevention of injuries in coal or other mines. Diesel particulate
matter (DPM) is a probable carcinogen that consists of tiny
particles present in diesel engine exhaust that can readily
penetrate into the deepest recesses of the lungs. Despite
ventilation, the confined underground mine work environment may
contribute to significant concentrations of particles produced by
equipment used in the mine. Underground miners are exposed to
higher concentrations of DPM than any other occupational group. As
a result, they face a significantly greater risk than other workers
of developing such diseases as lung cancer, heart failure, serious
allergic responses and other cardiopulmonary problems. The DPM rule
establishes a permissible exposure limit (PEL) to total carbon,
which is a surrogate for measuring a miner's exposure to DPM. The
rule includes a number of other requirements for the protection of
miners' health. The DPM existing rule contains information
collection requirements for underground MNM mine operators under §§
57.5060, 57.5065, 57.5066, 57.5070, 57.5071, and 57.5075(a) and
(b)(3).
The calculated responses have
been adjusted because the previous submission undercounted the
number of responses. There was no significant change in number of
respondents or burden hours, because these were correctly
calculated in the previous submission. The costs increased because
the estimated cost of maintaining respirators has increased.
Respondents from 173 to 173 (no change) Responses from 18,752 to
28,022 (increase of 9,270) Hours from 3,331 to 3,329 (decrease of
2) Costs from $176,363 to $512,679 (increase of $336,316)
