MSHA's standards for sealing abandoned
areas in underground coal mines includes requirements covering the
design and construction of new seals and the maintenance and repair
of all seals. Records that will be collected under this rule will
help assure that the construction and maintenance of seals are done
correctly; certified persons conducting sampling in sealed areas
are adequately trained; and results from sampling in sealed areas
are recorded, so that problems can be found and fixed.
The number of producing
underground coal mines has decreased from 361 to 301. In addition,
the percentage of sealed areas with seals of less than 120 psi
strength continues to decrease as operators build new, stronger
seals. Due to the decrease in respondents, responses decreased as
well from 90,360 to 54,857, and burden hours decreased from 9,057
to 6,380. Response time increased for annual burden hours and to
notify MSHA under section 75.336(c) but this increase in burden
hours did not offset the overall decrease in burden hours.
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
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
