Note to Reg Neg Committee: 

For your information, please find attached 3 revised pages that clarify 

that a "modification" is not considered a "new source" under the Clean Air Act 

Amendments. No action is necessary on your part. Both the House and Senate 

versions included modification, but we only recently discovered the final 

Amendments do not. As we stated throughout the negotiations, we will be 

consistent with whatever the Amendments require. Over the next few months, as 

we get copies of the new Act, we will be studying the new requirements. If 

any other necessary changes come to light, we will inform you prior to 

proposal; however, we foresee nothing substantive. 

Also, we will send a "clean" (i.e., no redline or strikeout) version of 

the regulation as soon as all the signatures are in.
