Re:		Correction of Error in Docket Document EPA-HQ-OAR-2003-0079-0996

We recently discovered that docket document EPA-HQ-OAR-2003-0079-0996
contained only a cover page for the document, “The Second Addendum to
the Economic Assessment for the 8-hour Ozone Implementation Rule; Phase
2, Final 8-hour Implementation Rule; Estimated Differences in Cost,
Emission Reductions, Energy, and Economic Impacts from Adopting a Less
Flexible RACT and RFP Implementation Framework Relative to the
Regulatory Baseline, A More Flexible Implementation Framework” (August
31, 2005).  We are therefore placing the document in the docket; due to
rules concerning the docket, the document is given a different docket
document number.
