 To amend section 111 of the Clean Air Act to clarify when a physical 
change in, or change in the method of operation of, a stationary source

    Be it enacted by the Senate and House of Representatives of the

SECTION 1. CLARIFICATION OF DEFINITION OF A MODIFICATION.

    Paragraph (4) of section 111(a) of the Clean Air Act (42 U.S.C. 
7411(a)) is amended by adding at the end the following: ``For purposes 
of the preceding sentence, a physical change in, or change in the 
method of operation of, a stationary source increases the amount of any 
air pollutant emitted by such source only if the maximum achievable 
hourly emissions rate of such source after the change will be higher 
than--
                    ``(A) the maximum achievable hourly emissions rate 
                of such source as it was originally designed; and
                    ``(B) the maximum hourly emissions rate of such 
                source that was actually achieved during the 10-year 
                period preceding such change.''.
