Main fans for all underground metal
and nonmetal gassy mines must have pressure-recording systems. The
fans are required to be examined daily while operating if persons
are underground. The pressure-recording systems indicate whether
the fans are in good operating condition. The pressure recordings
are required to be kept one year.
Respondents: There has been an
increase of 1 respondent (from 6 to 7). This is due to an increase
in the Agency estimate of the number of mines affected. Responses:
There has been an increase of 2,970 responses (from 3,960 to
6,930). This is due to an increase in the Agency estimate of the
number of mines affected and the addition of the burden for a
supervisor to certify the inspection by countersigning. Burden
Hours: There has been a increase of 406 burden hours (from 1,980 to
2,386). This is due to the addition of the burden for a supervisor
to certify the inspection by countersigning. Cost: There has been
an increase in annual costs of $1,600 (from $1,200 to $2,800). This
is due to an increase in the Agency estimate of the number of mines
affected as well as the addition of annual replacement costs for
the pressure recording devices. Even though the cost to replace the
pressure recording devices had not been previously included, MSHA
has determined that they are necessary to perform the collection of
information and therefore the cost should be included.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
