Requires coal mine operators to submit
to MSHA annual reports and certification on refuse piles and
impoundments and to keep records of the results of weekly
examinations and instrumentation monitoring. Impoundments are
structures that can impound water, sediment, or slurry or any
combination of materials; and refuse piles are deposits of coal
mine waste (other than overburden or spoil) that are removed during
mining operations or separated from mined coal and deposited on the
surface. The failure of these structures can have a devastating
affect on a community. To avoid or minimize such disasters,
standards have been promulgated for the design, construction, and
maintenance of these structures; for annual certifications; for
certification for hazardous refuse piles; for the frequency of
inspections; and the methods of abandonment for impoundments and
impounding structures.
MSHA records show a decrease in
the number of respondents from 642 to 629. The number of active
impoundments declined due to an industry effort to keeping existing
facilities in operation longer by increasing the elevation and
capacity for refuse disposal at impoundments rather than developing
new sites because of the relative scarcity of suitable locations.
There was a decrease in the number of impoundment plans. In
addition, there was an increase in the number of inspections. The
previous submission estimated that more operators would take
advantage of a reduced inspection schedule of less than every seven
days. Less than 10% of the total population of impoundments,
however, have requested an inspection schedule less often than
every 7 days, therefore 52 inspections per year is used to reflect
the actual number of plans that have been submitted requesting a
reduced inspection. The number of responses overall increased by
20,943 (from 10,422 to 31,365), and consequently, burden hours
increased by 45,993 (from 30,579 to 76,572). These increases in the
burden hours are due an adjustment increase in the number of
inspections from 17 to 52 per year, impoundment plan revision
responses, abandonment plans, and recordkeeping associated with
weekly inspections and instrumentation monitoring. This burden
estimate also continues to recognize that 95 percent of the
engineering work associated with impoundments and refuse pile is
done by contract engineering firms. MSHA assesses a decrease of
$4,325,792 (from $7,782,720 to $3,456,928) in burden cost.
