Sec. 440.54  New source performance standards (NSPS).

    Except as provided in subpart L of this part any new source subject 
to this subpart must achieve the following NSPS representing the degree 
of effluent reduction attainable by the applications of the best 
available demonstrated technology (BADT):

mines obtaining titanium ores from lode deposits shall not exceed:
