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.

  • 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While the EPA is providing additional time for the public to submit comments on the draft guidance, we are also taking into consideration that there is a need to finalize the guidance as quickly as possible so that states, tribes, and air agencies have the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 We are therefore working to assure that the delays that result from this extension of the comment period on the draft guidance are kept to a minimum. In Start Printed Page 66927addition, as stated in the draft guidance, the EPA is also currently drafting a proposed rulemaking on specific elements of the draft guidance concerning the elements necessary for the section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.
