Abstract: Our current standards require that all underground coal mine operators develop and follow a mine ventilation plan for each mechanized mining unit that we approve. However, we do not have a requirement that provides for verification of each plan's effectiveness under typical mining conditions. Consequently, plans may be implemented by mine operators that could be inadequate to control respirable dust. In response to comments received on the July 2000 proposed rule for MSHA to withdraw the rule, MSHA published a new proposed rule on March 6, 2003. The proposed rule would have required mine operators to verify, through sampling, the effectiveness of the dust control parameters for each mechanized mining unit specified in the approved mine ventilation plan.

The use of approved powered air-purifying respirators and/or verifiable administrative controls would have been allowed as a supplemental means of compliance when MSHA had determined that all feasible engineering or environmental controls were exhausted.

Public hearings were held in May 2003, and the comment period, originally scheduled to close on June 4, 2003, was extended until July 3, 2003. On June 24, 2003, MSHA announced that all work on the final rule would cease and the rulemaking record would remain open in order to obtain information concerning Personal Dust Monitors being tested by NIOSH. A Federal Register notice was published on July 3, 2003, extending the comment period indefinitely.
