Box 12055, Environmental Protection Agency, Research Triangle Park, North Carolina 27711; telephone number: (919) 541-3165; and email address:                         *hansen.amanda@epa.gov.*

# SUPPLEMENTARY INFORMATION:

*Rationale.*                     The EPA received a request for additional time to review and comment on the supplemental proposed rule from a regulated entity (Freeport-McMorRan Miami, Inc.). This request is available in the docket (Docket ID No. EPA-HQ-OAR-2020-0430). They noted that a document in the docket (Docket ID No. EPA-HQ-OAR-2020-0430) contained typographical errors. Specifically, the memorandum that was intended to show the proposed rule edits (in redline strikeout) that would be necessary to incorporate the changes to 40 CFR part 63, subpart QQQ proposed in the action published on July 24, 2023 (88 FR 47415) was inadvertently converted to a clean document before it was posted to the docket. We posted the updated correct document to                     *https://www.epa.gov/​stationary-sources-air-pollution/​primary-copper-smelting-national-emissions-standards-hazardous-air,*                     to replace the previous document (that had the typographical errors). We also added the correct document to the docket, under Docket ID No. EPA-HQ-OAR-2020-0430, which is available at                     *https://www.regulations.gov,*                     and notified the entity within 8 days of publication of the supplemental notice. After considering this request, the EPA has decided to extend the public comment period by 15 days to provide all parties with an opportunity to review the updated document. The public comment period will now end on September 22, 2023.                

*Docket.*                     The EPA has established a docket for this rulemaking under Docket ID No. EPA-HQ-OAR-2020-0430. 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. EPA-HQ-OAR-2020-0430. 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                     *https://www.regulations.gov/​,*                     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                     *https://www.epa.gov/​dockets/​commenting-epa-dockets.*

                    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. For additional information about the EPA's public docket, visit the EPA Docket Center homepage at                     *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                           ( print page 57383)                        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. If sending CBI information through the postal service, please send it to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, P.O. Box 12055, Research Triangle Park, North Carolina 27711, Attention Docket ID No. EPA-HQ-OAR-2020-0430. The mailed CBI material should be double wrapped and clearly marked.
