## Abstract

This document contains corrections to the final rule published in the Federal Register on January 19, 2001, which addresses the exposure of underground coal miners to diesel particulate matter (dpm) (66 FR 5526).\1\ As discussed in the preamble to the final rule, Sec. 72.500 requires that all permissible equipment emit no more than 2.5 grams of dpm per hour. For nonpermissible, heavy-duty diesel- powered equipment, generators and compressors, Sec. 72.501 specifies an interim limit of 5.0 grams of dpm per hour, and a final limit of 2.5 grams of dpm per hour. Similarly, Sec. 72.502 specifies that nonpermissible light-duty equipment other than generators and compressors must emit no more than 5.0 grams of dpm per hour. Although the preamble discussion of these provisions made MSHA's intentions clear as to the emissions limits established in the final regulation, the preamble and the codified text of the final rule contained grammatical errors. Therefore, this correction document is necessary. These corrections are effective on May 21, 2001, the effective date of the final rule. ---------------------------------------------------------------------------
