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 slight
decrease in the number of new plans submitted for approval and a
decrease in the number of revisions to impoundment plans. The
number of active impoundments declined by 50 (from 692 to 642)
impoundments primarily 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. Another aspect contributing to the declining number of
active impoundments is the improvements in MSHA computer based
inventory. The MSHA Impoundments and Refuse Pile Inventory (IRPI)
has identified and eliminated duplicate reporting. The inventory
numbers are now much more reliable with the districts providing
data in a consistent format. The number of responses also decreased
by 632 (from 11,054 to 10,422). Consequently, burden hours
decreased by 1,502 (from 32,081 to 30,579) due to a slight
reduction in the number of new impoundment plans or major revisions
to existing impoundments. This burden estimate also continues to
recognizing that 95 percent of the engineering work associated with
impoundments and refuse pile is done by contract engineering firms.
Consequently, this resulted in MSHA assessing an increase of
$966,260 (from $6,816,460 to $7,782,720) burden cost.
