# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of proposed settlement agreement; request for public comment.

# SUMMARY:

                        In accordance with the Clean Air Act, as amended (“CAA” or the “Act”), notice is hereby given of a proposed Settlement Agreement to resolve petitions for review filed by the State of Wyoming (“Wyoming”) and PacifiCorp with respect to PacifiCorp's Wyodak electric generating unit (EGU). In 2014, Wyoming and PacifiCorp filed petitions for review in the United States Court of Appeals for the Tenth Circuit, challenging EPA's final rule, in which the Agency partially approved and partially disapproved elements of Wyoming's Regional Haze State Implementation Plan (SIP), and promulgated a Federal Implementation Plan (FIP) to address the disapproved elements. In the Final rule, EPA,                         *inter alia,*                         disapproved Wyoming's determination concerning nitrogen oxide (NOX) best available retrofit technology (BART) for Wyodak and promulgated a FIP addressing NOX                         BART requirements for Wyodak. The Settlement Agreement would resolve Wyoming's and PacifiCorp's challenges to the final rule. Under the proposed Settlement Agreement, the parties agree to take certain specified actions.                    

# DATES:

Written comments on the proposed settlement agreement must be received by February 3, 2021.

The EPA may publish any comment received to its public docket. Do not submit to EPA's docket at                     *https://www.regulations.gov*                     any information you consider to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. 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.*                     For additional information about submitting information identified as CBI, please contact the person listed in the                     **FOR FURTHER INFORMATION CONTACT**                     section of this document.

If you submit an electronic comment, EPA recommends that you include your name, mailing address, and an email address or other contact information in the body of your comment. This ensures that you can be identified as the submitter of the comment and allows EPA to contact you in case EPA cannot read your comment due to technical difficulties or needs further information on the substance of your comment. Any identifying or contact information provided in the body of a comment will be included as part of the comment that is placed in the official public docket and made available in EPA's electronic public docket. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment.

The electronic public docket system is an “anonymous access” system, which means EPA will not know your identity, email address, or other contact information unless you provide it in the body of your comment.                

Please ensure that your comments are submitted within the specified comment period. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.
