amend sections #aaa1 #afi1 and #aga of

  7#b7 by inserting before the period at
 the end the following3 4 ,for purposes 
of the preceding sentence1 a change     
increases the amount of any air         
pollutant emitted by such source only if
 the maximum hourly emission rate of an 
air pollutant that is achievable by such

 source after the change is higher than 
the maximum hourly emission rate of such
 air pollutant that was achievable by   
such source during any hour in the      
#aj-year period immediately preceding   
the change2 and  7#c7 by adding at the  
end the following3  7,b7                
,notwithstanding subparagraph 7,a71 the 
term modification does not include a    
change at a stationary source that is   
designed-- 7i7 to reduce the amount of  
any air pollutant emitted by the source 
per unit of production2 or  7ii7 to     
restore1 maintain1 or improve the       
reliability of operations at1 or the    
safety of1 the source1  except1 with    
respect to either clause 7i7 or 7ii71   
when the change would be a modification 
as defined in subparagraph 7,a7 and the 
,administrator determines that the      
increase in the maximum achievable      
hourly emission rate of a pollutant from
 such change would cause an adverse     
effect on human health or the

requirements of subsection 7a7 that     
apply with respect to authorizing       
construction of a major emitting        
facility shall apply only with respect  
to construction that involves physical  
construction of the discrete parts of an
 emissions unit at a major emitting     
facility1 regardless of whether the     
construction involves other physical    
on-site activities at the major emitting

physical on-site activity that-- 7,a7   
may be costly2  7,b7 may significantly  
alter the site2  7,c7 is permanent in

 ,definition of emissions unit ,in this 
subsection1 the term emissions unit     
means any part of a stationary source   
that emits1 or has the potential to     
emit1 any air pollutant that is         
regulated under this title4  4  7b7

section #afi7b7 of the ,clean ,air ,act

read as follows3  7,c7 ,the term        
construction1 when used in connection   
with a major emitting facility1 includes
 a modification 7as defined in section  
#aaa7;a77 at such facility1 except that 
for purposes of this subparagraph a     
modification does not include a change  
at a major emitting facility that does  
not result in a significant emissions   
increase1 or a significant net emissions
 increase1 in annual actual emissions at
 such facility4  4  #d4 ,clarification

modifications and modified mean a       
modification as defined in section      
#aaa7;a77#d71 except that such terms do 
not include a change at a major emitting
 facility that does not result in a     
significant emissions increase1 or a    
significant net emissions increase1 in  
annual actual emissions at such

the end the following3 ,the construction
 for which a permit is required under   
this paragraph is construction that     
involves physical construction of the   
discrete parts of an emissions unit 7as 
defined in section #afe7;f77#b77 at a   
major stationary source1 regardless of  
whether the construction involves other 
physical on-site activities at the major
