SUPPLEMENTARY INFORMATION:

I. Background

      On March 6, 2003, (68 FR 10940), the Secretaries of Labor and Health and Human Services published a notice, ``Determination of Concentration of Respirable Coal Mine Dust (Single Sample),'' reopening the rulemaking record on a July 7, 2000 joint proposed rule that would determine that the average concentration of respirable dust to which each miner in the active workings of a coal mine is exposed can be accurately measured over a single shift. In that proposed rule the Secretaries proposed to rescind a previous 1972 finding by the Secretary of the Interior and the Secretary of Health, Education and Welfare, on the accuracy of single shift sampling (63 FR 42068).

II. Extension of Comment Periods

The comment periods for the reopening of the Single Sample rule were scheduled to close on June 4, 2003 (68 FR 10940, 68 FR 12641). However, in response to requests from the public for additional time to prepare their comments, the comment periods have been extended 30 days until July 3, 2003. All comments must be submitted to MSHA by this date.

     Dated: May 15, 2003.
Elaine L. Chao,
Secretary of Labor.
     Dated: May 23, 2003.
