Under Section 101(a) of the Federal
Mine Safety and Health Act of 1977 (the Mine Act), the Secretary
may by rule in accordance with procedures set forth in this section
and in accordance with section 553 of Title 5, United States Code
(without regard to any reference in such section to sections 556
and 557 of such title), 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. In addition, Section 303 requires that all coal mines be
ventilated by mechanical ventilation equipment installed and
operated in a manner approved by an authorized representative of
the Secretary and such equipment be examined daily and a record be
kept of such examination. Underground coal mines usually present
harsh and hostile working environments. The ventilation system is
the most vital life support system in underground mining and a
properly operating ventilation system is essential for maintaining
a safe and healthful working environment. Lack of adequate
ventilation in underground mines has resulted in fatalities from
asphyxiation and explosions. An underground mine is a maze of
tunnels that must be adequately ventilated with fresh air to
provide a safe environment for miners. Methane is liberated from
the strata, and noxious gases and dusts from blasting and other
mining activities may be present. The explosive and noxious gases
and dusts must be diluted, rendered harmless, and carried to the
surface by the ventilating currents. Sufficient air must be
provided to maintain the level of respirable dust at or below 2
milligrams per cubic meter of air and air quality must be
maintained in accordance with MSHA standards. Mechanical
ventilation equipment of sufficient capacity must operate at all
times while miners are in the mine. Ground conditions are subject
to frequent changes, thus sufficient tests and examinations are
necessary to ensure the integrity of the ventilation system and to
detect any changes that may require adjustments in the system.
Records of tests and examinations are necessary to ensure that the
ventilation system is being maintained and that changes which could
adversely affect the integrity of the system or the safety of the
miners are not occurring. These examination, reporting and
recordkeeping requirements of §§ 75.310, 75.312, 75.342, 75.351,
75.360 through 75.364, 75.370, 75.371, and 75.382 also incorporate
examinations of other critical aspects of the underground work
environment such as roof conditions and electrical equipment which
have historically caused numerous fatalities if not properly
maintained and operated.

Respondents: There has been a
decrease in the number of respondents from 434 to 255 underground
coal mines. Responses: Due to a reduction in underground coal
respondents there is a decrease of 737,104 responses from the
previously approved 1,902,012 responses to the current total
request of 1,164,908 for ventilation plan development as well as
certification of mine examinations. Hours: Due to a reduction in
underground coal respondents there is a decrease of 171,074 burden
hours from the previously approved 313,624 hours to the current
total request of 142,550 for ventilation plan development as well
as certification of mine examinations. Costs: Due to the decrease
in underground coal mines, there was a $27,112 decrease in
estimated costs from the previously approved $118,982 to the
current total estimate of $91,870.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
