30 CFR Part 75
RIN 1219-AB52
Sealing of Abandoned Areas
AGENCY: Mine Safety and Health Administration (MSHA), Labor.
ACTION: Correcting amendments.
-----------------------------------------------------------------------
SUMMARY: MSHA published a final rule in the Federal Register on April
18, 2008 (73 FR 21182) on Sealing of Abandoned Areas in underground
coal mines. The final rule incorrectly listed cross-references in Sec.
75.336(b)(1) and Sec. 75.336(c). This document corrects the final rule
by revising these sections.
DATES: Effective Date: The corrections are effective May 14, 2008.
FOR FURTHER INFORMATION CONTACT: Patricia W. Silvey, Director, Office
of Standards, Regulations, and Variances, MSHA, 1100 Wilson Blvd., Room
2350, Arlington, Virginia 22209-3939, silvey.patricia@dol.gov (e-mail),
(202) 693-9440 (voice), or (202) 693-9441 (telefax). This document is
available on the Internet at http://www.msha.gov/REGSINFO.HTM.
SUPPLEMENTARY INFORMATION: As published, the preamble incorrectly
referenced a section of the final rule. On page 21193, in the first
column, in the first line, ``Sec. 75.335(a)(1)(iii)'' should be
``Sec. 75.336(a)(1)(iii).'' The sentence should read ``Under final
Sec. 75.336(a)(1)(iii) for less than 120 psi seals constructed after
April 18, 2008, the District Manager cannot approve different sampling
locations and frequencies in the ventilation plan until after a minimum
of 14 days and after seals have reached design strength.''
In addition, the final rule incorrectly listed cross-references in
Sec. 75.336(b)(1) and Sec. 75.336(c). This document corrects the
final rule by revising these sections.
