A. What should I consider as I prepare my comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through http://www.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@example.com, Attention Docket ID No. OAR-2010-1059.
2. Tips for Preparing Your Comments. When submitting comments, remember to:
- Identify the 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 part or section number in the guidance.
- Explain why you agree or disagree with EPA's guidance; and suggest alternatives and substitute language that would help to clarify or better explain the points made and positions taken in EPA's guidance document.
II. Background Back to Top
The purpose of this notice is to solicit public comments on EPA's recently posted draft non-binding guidance titled, “Guidance for 1-Hour SO 2 NAAQS SIP Submissions.” This document is available online at http://www.epa.gov/airquality/sulfurdioxide/implement.html or within the associated docket, EPA-HQ-OAR-2010-1059.
The draft guidance document is intended to assist state and tribal governments in preparing State Implementation Plan (SIP) submittals under section 110(a)(1) of the Clean Air Act (CAA) to address implementation, maintenance, and enforcement of the 1-hour primary sulfur dioxide (SO 2) National Ambient Quality Standards (NAAQS). The CAA directs states to submit these SIPs to EPA by no later than June 3, 2013, which is 3 years after promulgation of the primary SO 2 NAAQS. To be approved, the EPA would expect the SIP submittals to demonstrate through the use of refined air quality dispersion modeling that the affected areas will attain the standard as expeditiously as practicable. This draft guidance provides the basic information that states, tribes and emission sources would need to address the section 110(a)(1) SIP submittal for the 1-hour SO 2 NAAQS including modeling guidance. After receiving timely submitted public comments on the draft guidance, the EPA plans to issue updated non-binding guidance. In addition, the EPA will continue to work closely with states and tribes to address issues arising under the section 110(a)(1) SIP submittals.
EPA invites public comment on all aspects of this draft guidance during the 30-day comment period. The draft guidance is not a regulation or any other kind of final action and does not establish binding requirements on the EPA or any state, local, or tribal agency or any emissions source. While the EPA has established a docket and is requesting public comment on the draft guidance, this procedure does not alter the nature or effect of the draft guidance and does not constitute a formal rulemaking process or require the EPA to respond to public comments in the updated guidance before the EPA or other agencies may use the guidance in reaching decisions related to SIPs submitted under section 110(a)(1). The EPA retains the discretion to revise its guidance, issue additional guidance, propose regulations as appropriate, and to utilize information submitted in public comments to inform future decisions. Because this draft guidance does not constitute a formal rulemaking action, the EPA is not required to respond to comments, but intends to take significant comments under consideration in amending or updating the non-binding guidance. To the extent that the EPA determines that comments received during the 30-day comment period justify corrections or clarifications to the guidance, the EPA may revise and reissue the guidance and post the revised document at: http://www.epa.gov/airquality/sulfurdioxide/implement.html.
Please refer to the ADDRESSES section above in this document for specific instructions on submitting comments.
