Section 103(h) of the Federal Mine
Safety and Health Act of 1977 (Mine Act), 30 U.S.C. § 813,
authorizes MSHA to collect information necessary to carry out its
duty in protecting the safety and health of miners. Title 30 C.F.R.
§ 77.1900 requires underground coal mine operators to submit for
approval a plan that will provide for the safety of workmen in each
slope or shaft that is commenced or extended from the surface to
the underground coal mine. Each slope or shaft sinking operation is
unique in that each operator uses different methods and equipment
and encounters different geological strata which make it impossible
for a single set of regulations to ensure the safety of the miners
under all circumstances. This makes an individual slope or shaft
sinking plan necessary. The plan must be consistent with prudent
engineering design. Plans include the name and location of the
mine; name and address of the mine operator; a description of the
construction work and methods to be used in construction of the
slope or shaft, and whether all or part of the work will be
performed by a contractor; the elevation, depth and dimensions of
the slope or shaft; the location and elevation of the coalbed; the
general characteristics of the strata through which the slope or
shaft will be developed; the type of equipment which the operator
proposes to use; the system of ventilation to be used; and
safeguards for the prevention of caving during excavation.
The burden hour decrease of 100
hours (from 1,460 hours to 1,360 hours) and the associated costs is
due to fewer new underground coal mine openings, and as a result, a
decreased number of shaft and slope projects. MSHA records show
that there were less shafts and slopes under construction during
the year 2012 than 2009. There was a decrease from 73 responses to
68 due to less plans in this adjustment and less respondents
submitting plans (73 to 31 respondents/mines). The prior submission
double counted revisions as responses from additional respondents.
This submission more accurately notes that respondents submit
multiple responses per respondent. There was also a cost burden
decrease (from $1,272 to $51) resulting from a decrease in the
number of shaft and slope plans submitted for facilities under
construction and the increase in the number of plans sent to MSHA
electronically.
