Availability of Additional Information Supporting the Rule To 
Reduce Interstate Transport of Fine Particulate Matter and Ozone (Clean 
Air Interstate Rule)

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. This 
new modeling platform consists of new meteorological data, updated 
emissions data, an updated air quality model, and revised procedures 
for projecting future air quality concentrations. The additional 
information also includes revised state NOX budgets.

DATES: Documents were placed in the CAIR docket on or about July 27, 
2004. Comments must be received on or before August 27, 2004. Please 
refer to SUPPLEMENTARY INFORMATION for additional information on the 
comment period.

ADDRESSES: Submit your comments, identified by Docket ID No. OAR-2003-
0053, by one of the following methods:
    A. Federal Rulemaking Portal: http://www.regulations.gov. Follow 
the on-line instructions for submitting comments.
    B. Agency Web site: http://www.epa.gov/edocket. EDOCKET, EPA's 
electronic public docket and comment system, is EPA's preferred method 
for receiving comments. Follow the on-line instructions for submitting 
comments.
    C. E-mail: [email protected]
    D. Mail: Air Docket, Clean Air Interstate Rule, Environmental 
Protection Agency, Mail Code: 6102T, 1200 Pennsylvania Ave., NW.,

    Instructions: Direct your comments to Docket ID No. OAR-2003-0053. 
The EPA's policy is that all comments received will be included in the 
public docket without change and may be made available online at http://www.epa.gov/edocket, including any personal information provided, 
unless the comment includes information claimed to be Confidential 
Business Information (CBI) or other information whose disclosure is 
restricted by statute. Do not submit information that you consider to 
be CBI or otherwise protected through EDOCKET, regulations.gov, or e-
mail. The EPA EDOCKET and the Federal regulations.gov Web sites are 
``anonymous access'' systems, which means EPA will not know your 
identity or contact information unless you provide it in the body of 
your comment. If you send an e-mail comment directly to EPA without 
going through EDOCKET or regulations.gov, your e-mail address will be 
automatically captured and included as part of the comment that is 
placed in the public docket and made available on the Internet. If you 
submit an electronic comment, EPA recommends that you include your name 
and other contact information in the body of your comment and with any 
disk or CD-ROM you submit. If EPA is unable to read your comment and 
contact you for clarification due to technical difficulties, EPA may 
not be able to consider your comment. Electronic files should avoid the 
use of special characters, any form of encryption, and

be free of any defects or viruses. For additional information about 
EPA's public docket visit EDOCKET on-line or see the Federal Register 
of May 31, 2002 (67 FR 38102). For additional instructions on 
submitting comments, go to Unit I of the SUPPLEMENTARY INFORMATION 
section of this document.

I. Additional Information on Submitting Comments

A. How Can I Help EPA Ensure That My Comments Are Reviewed Quickly?

    To expedite review of your comments by Agency staff, you are 
encouraged to send a separate copy of your comments, in addition to the 
copy you submit to the official docket, to Douglas Solomon, U.S. EPA, 
Office of Air Quality Planning and Standards, Emissions Modeling and

B. What Should I Consider as I Prepare My Comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
EDOCKET, regulations.gov or e-mail. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as 
CBI and then identify electronically within the disk or CD ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information 
claimed as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2. Send or deliver information 
identified as CBI only to the following address: Roberto Morales, U.S. 
EPA, Office of Air Quality Planning and Standards, Mail Code C404-02, 
Research Triangle Park, NC 27711, telephone (919) 541-0880, e-mail at 
[email protected], Attention Docket ID No. OAR-2003-0053.
    2. Tips for Preparing Your Comments. When submitting comments, 
remember to:
    i. Identify the rulemaking by docket number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. Follow directions--The agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
    vi. Provide specific examples to illustrate your concerns, and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period 
deadline identified.
