II. Background

The purpose of this notice is to solicit public comments on EPA's recently posted guidance titled, “PSD and Title V Permitting Guidance for Greenhouse Gases.” This document has been determined to be an EPA Significant Guidance Document per the OMB Bulletin definition and is included on the EPA list of significant guidance documents. It is available online at​regulations/​guidance/​byoffice-oar.html or within the associated docket.

The guidance document is intended to assist permit writers and permit applicants in addressing the Prevention of Significant Deterioration (PSD) and title V permitting requirements for greenhouse gases (GHGs) that begin to apply on January 2, 2011, to certain sources.[1] The document: (1) Describes, in general terms and through examples, the requirements of the PSD and title V permit regulations and how these requirements apply to GHGs; (2) reiterates and emphasizes relevant past EPA guidance on the PSD and title V review processes for other regulated air pollutants; and (3) provides additional recommendations and suggested methods for meeting the permitting requirements for GHGs. We believe this guidance provides the basic information that permitting agencies and applicants need to address GHG emissions in permits. In addition, EPA will continue to work closely with all stakeholders to ensure a smooth transition to the permitting of GHGs.

EPA invites public comment on all aspects of its guidance document during the 14-day comment period. The guidance is not a regulation and does not establish binding requirements on EPA or any state, local, or tribal agency that is authorized to issue PSD or title V permits to satisfy requirements of the Clean Air Act; however, this guidance is hereby in effect and, consequently, EPA and other agencies may apply this guidance without, and regardless of, any additional action by EPA specific to this guidance. Although EPA has established a docket and is requesting public comment on the guidance, this procedure does not alter the nature or effect of the guidance and does not constitute a formal rulemaking process or require EPA to respond to public comments on the guidance before EPA or other agencies may apply the guidance in any permitting decision. After considering public comments, 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 proposed permit decisions. An additional opportunity for public comment is required for any proposed decision by EPA or another agency to issue a PSD or title V permit, and such comments may address the applicability of this guidance to specific permit applications.

Most immediately, EPA seeks comment on whether the guidance Start Printed Page 70256presented in the document contains any technical or calculation errors. EPA also will consider comments on other aspects of the guidance. Because the guidance does not constitute a formal rulemaking action, EPA does not intend to respond to comments, but will take such comments under consideration. To the extent that EPA determines that comments received during the 14-day comment period justify corrections or clarifications to the guidance, EPA may revise and reissue the permitting guidance and post the revised document on the significant guidance Web site.

Please refer to the ADDRESSES section above in this document for specific instructions on submitting comments.
