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.

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.''
