Title 30 CFR 57.22004(c) requires
operators of underground M/NM mines to notify the Mine Safety and
Health Administration (MSHA) as soon as possible if any of the
following events occur: (a) there is an outburst that results in
0.25 percent or more methane in the mine atmosphere, (b) there is a
blowout that results in 0.25 percent or more methane in the mine
atmosphere, (c) there is an ignition of methane, or (d) air sample
results indicate 0.25 percent or more methane in the mine
atmosphere of a I-B, I-C, II-B, V-B, or Category VI mine. Under §§
57.22239 and 57.22231, if methane reaches 2.0 percent in a Category
IV mine or if methane reaches 0.25 percent in the mine atmosphere
of a Subcategory I-B, II-B, V-B, or VI mine, MSHA shall be notified
immediately. Although the standards do not specify how MSHA is to
be notified, MSHA anticipates that the notifications would be made
by telephone. Title 30 CFR 57.22229 and 57.22230 require that the
mine atmosphere be tested for methane and/or carbon dioxide at
least once every seven days by a competent person or atmospheric
monitoring system or a combination of both. Section 57.2229 applies
to underground M/NM mines categorized as I-A, III, and V-A mines
where the atmosphere is tested for both methane and carbon dioxide.
Section 57.22230 applies to underground M/NM mines categorized as
II-A mines where the atmosphere is tested for methane. Where
examinations disclose hazardous conditions, affected miners must be
informed. Title 30 CFR 57.22229(d) and 57.22230(c) require that the
person performing the tests certify by signature and date that the
tests have been conducted. Certifications of examinations shall be
kept for at least one year and made available to authorized
representatives of the Secretary of Labor.
