*Background on Today's Action:*                     In this action, EPA is extending the public comment period on the July 27, 2010 Supplemental Proposal to the Proposed Confidentiality Determinations for Data Required Under the Mandatory Greenhouse Gas Reporting Rule (“Supplemental CBI Proposal,” 75 FR 43889). EPA is extending the comment period for the Supplemental CBI Proposal to September 7, 2010.                

On July 7, 2010, EPA published the Proposed Confidentiality Determinations for Data Required Under the Mandatory Greenhouse Gas Reporting Rule and Proposed Amendment to Special Rules Governing Certain Information Obtained Under the Clean Air Act (“CBI Proposal,” 75 FR 39094). The comment period for the CBI Proposal ends on September 7, 2010.

On July 27, 2010, EPA published the Supplemental CBI Proposal; the comment period for the Supplemental CBI Proposal would have ended on August 26, 2010.

EPA received comments requesting an extension of the public comment period for the Supplemental CBI Proposal to September 7, 2010. Commenters noted that the CBI Proposal and the Supplemental CBI Proposal both concern the confidentiality of data collected under the Greenhouse Gas Reporting Program. Commenters also noted how comments on the two proposals might be easily consolidated into one document. Therefore, to facilitate submission of public comments, EPA is extending the comment period for the Supplemental CBI Proposal to September 7, 2010 so that the comment period for both actions ends on the same day.
