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, [email protected] (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.
