SUPPLEMENTARY INFORMATION: 

A. Instructions for Submitting Comments

    EPA's policy is to include all comments received in the public 
docket without change. We may make comments available online at http://www.regulations.gov, including any personal information provided, 
unless the comment includes information claimed to be CBI or other 
information for which disclosure is restricted by statute. Do not 
submit information that you consider to be CBI or that is otherwise 
protected through http://www.regulations.gov or email. The http://www.regulations.gov web site is an ``anonymous access'' system, 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 email comment 
directly to EPA, without going through http://www.regulations.gov, we 
will include your email address 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 cannot read your comment due to technical 
difficulties and cannot contact you for clarification, EPA may not be 
able to consider your comment. Electronic files should not include 
special characters or any form of encryption, and be free of any 
defects or viruses.

B. Docket

    The proposed rule published on December 21, 2012, relies on 
documents, information and data that are listed in the index on http://www.regulations.gov under docket number EPA-R09-OAR-2012-0904. Although 
listed in the index, some information is not publicly available (e.g., 
Confidential Business Information (CBI)). Certain other material, such 
as copyrighted material, is publicly available only in hard copy form. 
Publicly available docket materials are available either electronically 
at http://www.regulations.gov or in hard copy at the Planning Office of 
the Air Division, AIR-2, EPA Region 9, 75 Hawthorne Street, San 
Francisco, CA 94105. EPA requests that you contact the individual 
listed in the FOR FURTHER INFORMATION CONTACT section to view the hard 
copy of the docket. You may view the hard copy of the docket Monday 
through Friday, 9-5:00 PST, excluding Federal holidays.

C. Submitting Confidential Business Information

    Do not submit CBI to EPA through http://www.regulations.gov or 
email. Clearly mark the part or all of the information that you claim 
as 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 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, you must submit a copy of the 
comment that does not contain the information claimed as CBI for 
inclusion in the public docket. We will not disclose information so 
marked except in accordance with procedures set forth in 40 CFR part 2.

D. Tips for Preparing Comments

    When submitting comments, remember to:
     Identify the rulemaking by docket number and other 
identifying information (e.g., subject heading, Federal Register date 
and page number).
     Explain why you agree or disagree; suggest alternatives 
and substitute language for your requested changes.
     Describe any assumptions and provide any technical 
information and/or data that you used.
     If you estimate potential costs or burdens, explain how 
you arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
     Provide specific examples to illustrate your concerns, and 
suggest alternatives.
     Explain your views as clearly as possible, avoiding the 
use of profanity or personal threats.
