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.
Tommy G. Thompson,
Secretary, Department of Health and Human Services.
