Determination of Concentration of Respirable Coal Mine Dust

This document reopens the rulemaking record and extends the comment period for the proposed rule addressing Determination of Concentration of Respirable Coal Mine Dust, (Single Sample) published in the Federal Register on July 7, 2000 and reopened for public comment on March 6, 2003. The Agencies have decided to reopen the rulemaking record and further extend the comment period in order to obtain further information on Personal Dust Monitors (PDMs), a new technology which is currently being tested by NIOSH. The rulemaking record and comment period will remain open until further notice is published in the Federal Register. All comments received will be entered into the rulemaking record.
