Sec.  71.701  Sampling; general requirements.



    (a) Air samples will be taken by the Secretary and will be analyzed 

to determine the concentrations of noxious or poisonous gases, dusts, 

fumes, mists, and vapors in surface installations and at surface 

worksites.

    (b) Upon written notification by the Secretary to the operator of an 

underground coal mine or of a surface coal mine, the operator shall 

conduct any additional air sampling tests and analyses as the Secretary 

may from time to time require in order to ensure compliance with the 

standards set forth in Sec.  71.700 in each surface installation and at 

each surface worksite.

    (c) Where concentrations of airborne contaminants in excess of the 

applicable threshold limit values and permissible excursions are known 

by the operator to exist in a surface installation or at a surface 

worksite, he shall immediately provide necessary control measures to 

assure compliance with Sec.  71.700.

    (d) Where the operator has reasonable grounds to believe that 

concentrations of airborne contaminants in excess of the applicable 

threshold limit values and permissible excursions exist, or are likely 

to exist, he shall promptly conduct appropriate air sampling tests to 

determine the concentration of any airborne contaminant which may be 

present and immediately provide the necessary control measures to assure 

compliance with Sec.  71.700.
