Each operator of a surface coal mine
is required under 30 CFR 77.1000 to establish and follow a ground
control plan that is consistent with prudent engineering design and
which will ensure safe working conditions. The mine operator is
required by § 77.1000-1 to file the ground control plan under §
77.1000 for highwalls, pits and spoil banks with the appropriate
District Manager. The mining methods employed by the operator are
selected to ensure highwall, pit, and spoil bank stability. In the
event of a highwall failure or material dislodgment, there may be
very little time to escape possible injury; therefore, preventive
measures must be taken. Each plan is based on the type of strata
expected to be encountered, the height and angle of highwalls and
spoil banks, and the equipment to be used at the mine. The plan is
used to show how the mine operator will maintain safe conditions
around the highwalls, pits, and spoil banks. Each plan is reviewed
by MSHA to ensure that highwalls, pits, and spoil banks are
maintained in a safe condition through the use of sound engineering
design.
Respondents: There has been an
increase of 18 respondents (from 925 to 943) due to a change in the
number of surface coal mines requiring a ground control plan to be
filed with MSHA. Responses: There has been an Increase of 517
responses (from 327 to 844). MSHA believes this reported increase
is due to MSHA's main office having improved its data collection in
recent years concerning the number and type of ground control plans
submitted by mine operators to the various district offices.
Previously, these data were optionally submitted by the district
offices to MSHA's central database; submission of these data by
district offices is now required by headquarters. Burden Hours:
There has been an increase of 2,999 hours (from 2,841 to 5,840).
Because of this significant increase in the estimated number of
responses, there is also a significant increase in the estimate of
burden hours. In addition, MSHA reduced its estimate of clerical
time for copying, filing, and mailing plans from 1.0 hour to 0.1
hour for the burden hour estimate. MSHA determined that the 2009
estimate of an hour to copy, file, and mail a 6-page plan was an
over-estimate. Annual Cost Burden: There has been an increase of
$2,324 (from $520 to $2,844). MSHA increased its estimate of the
cost burden to submit plans by including copying costs in addition
to postage.
