                    Rationale.
                     On May 23, 2023, the Environmental Protection Agency (EPA) issued a proposal titled, New Source Performance Standards for Greenhouse Gas Emissions from New, Modified, and Reconstructed Fossil Fuel-Fired Electric Generating Units; Emission Guidelines for Greenhouse Gas Emissions from Existing Fossil Fuel-Fired Electric Generating Units; and Repeal of the Affordable Clean Energy Rule, 88 FR 33240 (May 23, 2023). In that proposal, the EPA provided a public comment period until July 24, 2023. The EPA has received several requests for additional time to review and comment on the proposed rules. After considering these requests, the EPA has decided to extend the public comment period another 15 days, until August 8, 2023, so that the comment period will be a total of 77 days. This extension will ensure that the public has additional time to review the proposed rules.
                
                
                    Docket.
                     The EPA has established a docket for this rulemaking under Docket ID No. EPAHQOAR20230072. All documents in the docket are listed in 
                    https://www.regulations.gov/.
                     Although listed, some information is not publicly available, 
                    e.g.,
                     Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Certain other material, such as copyrighted material, is not placed on the internet and will be publicly available only in hard copy. With the exception of such material, publicly available docket materials are available electronically in 
                    Regulations.gov
                    .
                
                
                    Instructions.
                     Direct your comments to Docket ID No. EPAHQOAR20230072. The EPA's policy is that all comments received will be included in the public docket without change and may be made available online at

                     including any personal information provided, unless the comment includes information claimed to be CBI or other information whose disclosure is restricted by statute. Do not submit electronically to 
                    https://www.regulations.gov/
                     any information that you consider to be CBI or other information whose disclosure is restricted by statute. This type of information should be submitted as discussed below.
                
                
                    The EPA may publish any comment received to its public docket. Multimedia submissions (audio, video, etc.) must be accompanied by a written comment. The written comment is considered the official comment and should include discussion of all points you wish to make. The EPA will generally not consider comments or comment contents located outside of the primary submission (
                    i.e.,
                     on the Web, cloud, or other file sharing system). For additional submission methods, the full EPA public comment policy, information about CBI or multimedia submissions, and general guidance on making effective comments, please visit

                    The 
                    https://www.regulations.gov/
                     website allows you to submit your comment anonymously, which means the EPA will not know your identity or contact information unless you provide it in the body of your comment. If you 
                    
                    send an email comment directly to the EPA without going through 
                    https://www.regulations.gov/,
                     your email address will be automatically captured and included as part of the comment that is placed in the public docket and made available on the internet. If you submit an electronic comment, the EPA recommends that you include your name and other contact information in the body of your comment and with any digital storage media you submit. If the EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, the EPA may not be able to consider your comment. Electronic files should not include special characters or any form of encryption and be free of any defects or viruses.

                    https://www.epa.gov/dockets.
                
                
                    Submitting CBI.
                     Do not submit information containing CBI to the EPA through 
                    https://www.regulations.gov/.
                     Clearly mark the part or all of the information that you claim to be CBI. For CBI information on any digital storage media that you mail to the EPA, note the docket ID, mark the outside of the digital storage media as CBI, and identify electronically within the digital storage media the specific information that is claimed as CBI. In addition to one complete version of the comments that includes information claimed as CBI, you must submit a copy of the comments that does not contain the information claimed as CBI directly to the public docket through the procedures outlined in instructions above. If you submit any digital storage media that does not contain CBI, mark the outside of the digital storage media clearly that it does not contain CBI and note the docket ID. Information not marked as CBI will be included in the public docket and the EPA's electronic public docket without prior notice. Information marked as CBI will not be disclosed except in accordance with procedures set forth in 40 Code of Federal Regulations (CFR) part 2.
                
                
                    Our preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol (FTP), or other online file sharing services (
                    e.g.,
                     Dropbox, OneDrive, Google Drive). Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                    oaqpscbi@epa.gov,
                     and as described above, should include clear CBI markings and note the docket ID. If assistance is needed with submitting large electronic files that exceed the file size limit for email attachments, and if you do not have your own file sharing service, please email 
                    oaqpscbi@epa.gov
                     to request a file transfer link.
