SUPPLEMENTARY INFORMATION:

I. General Information

A. What should I consider as I prepare my comments for EPA?

    1. Submitting CBI. Do not submit this information to the EPA 
through http://www.regulations.gov or email. 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 the 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, OAQPS 
Document Control Officer (C404-02), U.S. EPA, Research Triangle Park, 
NC 27711, Attention Docket ID No. EPA-HQ-OAR-2010-1059.
    2. Tips for Preparing Your Comments. When submitting comments, 
remember to:
     Identify the rulemaking by docket number and other 
identifying information (subject heading, Federal Register date and 
page number).
     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.
     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.

Make sure to submit your comments by the comment period deadline 
identified.

II. Background

    The purpose of this notice is to extend the public comment period 
on the EPA's recently posted draft non-binding guidance titled, 
``Guidance for 1-Hour SO2 SIP Submissions.'' The comment 
period notice published in the Federal Register on October 3, 2011 at 
76 FR 61098. The original comment period is scheduled to expire on 
November 2, 2011. By this notice, the EPA is extending the comment 
period for an additional 30 days resulting in the comment period ending 
on December 2, 2011. The EPA is extending the comment period due to 
public requests that have been made stating that additional time is 
required in order to fully evaluate the guidance and provide 
substantive comment.
    While the EPA is providing additional time for the public to submit 
comments on the draft guidance, we are also taking into consideration 
that there is a need to finalize the guidance as quickly as possible so 
that states, tribes, and air agencies have the necessary information to 
begin work on their State Implementation Plans submittals to address 1-
hour SO2 NAAQS. We are therefore working to assure that the 
delays that result from this extension of the comment period on the 
draft guidance are kept to a minimum. In

[[Page 66927]]

addition, as stated in the draft guidance, the EPA is also currently 
drafting a proposed rulemaking on specific elements of the draft 
guidance concerning the elements necessary for the section 110(a)(1) 
maintenance plan submittal. Since these two documents are linked in 
terms of issues involved, the EPA will be taking into consideration the 
comments that will be received on the draft guidance in making 
decisions concerning each document.
    The draft of the guidance document is available online at http://www.epa.gov/airquality/sulfurdioxide/implement.html or within the 
associated docket, EPA-HQ-OAR-2010-1059.

    Dated: October 25, 2011.
