SUPPLEMENTARY INFORMATION: On April 9, 1998 (63 FR 17492) MSHA published a proposed rule to reduce the risks to underground coal miners of serious health hazards that are associated with exposure to high concentrations of diesel particulate matter (dpm). DPM is a very small particle in diesel exhaust. Underground miners are exposed to far higher concentrations of this fine particulate than any other group of workers.
   The post-hearing comment period for the proposed rule addressing diesel particulate matter exposure of underground coal miners was scheduled to close April 30, 1999 (64 FR 7144).
   However, in response to requests from the public for additional time to prepare their comments, the record for the proposed rule will remain open until July 26, 1999. This provides a total of 15 months from the date of publication for the public to comment on the proposed rule.

Dated: April 21, 1999.
Marvin W. Nichols, Jr.,
Deputy Assistant Secretary for Mine Safety and Health.
