AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of data availability for the Clean Air Interstate Rule (CAIR).

SUMMARY:

The EPA is providing notice that it has placed in the docket for the CAIR (Docket No. OAR-2003-0053) additional information relevant to the rulemaking, including, among other things, a new modeling platform that EPA proposes to use to support the proposed rule.
