Re:	Documents from CAIR Rulemaking for IPM and NEEDS Information
Incorporated by Reference Into Docket

From:  	John Silvasi, Environmental Engineer

To:  	Docket EPA-HQ-OAR-2003-0079

The technical support document for the Federal Register notice “Phase
2 of the Final Rule to Implement the 8-Hour Ozone National Ambient Air
Quality Standard –Notice of Reconsideration” (proposed rule) notes
that EPA relied on certain data and analyses used in the Clean Air
Interstate Rule (CAIR).  Specifically, the TSD cited the Integrated
Planning Model (IPM) and National Electric Energy Data System (NEEDS). 
The specific data and information are found in the CAIR docket in the
following documents:

-  Base Case_2010_Parsed: EPA-HQ-OAR-2003-0053-1904

-  IPM 2004 (v.2.1.9) Documentation: EPA-HQ-OAR-2003-0053-1901

-  NEEDS 2004:  EPA-HQ-OAR-2003-0053-1686

We are incorporating these documents by reference into Docket
EPA-HQ-OAR-2003-0079 (“Final Rule To Implement the 8-Hour Ozone
National Ambient Air Quality Standard”).

 Federal Register of  May 12, 2005  (70 FR 25162).
