the ,committee on ,energy and ,commerce 
,a ,,bill  ,to amend sections #aaa1     
#afi1 and #aga of the ,clean ,air ,act  
to clarify when a physical change in1 or
 change in the method of operation of1 a
 stationary source constitutes a        
modification or construction1 and for   
other purposes4  #a4 ,short title ,this

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           
environment4  4  #c4 ,clarification of  
definition of construction for          
prevention of significant deterioration 
,subparagraph 7,c7 of section #afi7b7 of
 the ,clean ,air ,act 7#db ,u4,s4,c4    
#gdgi7b77 is amended to 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 of     
definition of modifications and modified
 for nonattainment areas ,paragraph 7#d7
 of section #aga of the ,clean ,air ,act

 7#db ,u4,s4,c4 #geja7 is amended to    
read as follows3  7#d7 ,the terms       
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         
facility4  4  #e4 ,rule of construction 
,nothing in this ,act or the amendments 
made by this ,act shall be construed to 
treat any change as a modification for  
purposes of any provision of the ,clean
