Air Plan Approval; Arkansas; Regional Haze and Interstate Visibility Transport Federal Implementation Plan;
Withdrawal of Federal Implementation Plan Provisions for the Domtar Ashdown Mill Environmental Protection Agency EPA.
ACTION: Final rule.
AGENCY:

The Environmental Protection Agency EPA is taking final action to withdraw the remaining portion of a Federal Implementation Plan FIP for Arkansas that was published in the Federal Register on September 27, 2016, which addressed certain regional haze obligations for the first implementation period for the Domtar Ashdown Mill.
Specifically, this remaining portion of the FIP we are withdrawing contains best available retrofit technology BART requirements for sulfur dioxide SO2 and nitrogen oxide NOX for Domtar Ashdown Mill Power Boiler No.
1; and SO2, NOX, and particulate matter PM BART requirements for Power Boiler No. 2. These portions of the FIP
are being replaced by a revision to the Arkansas State Implementation Plan SIP containing SO2, NOX, and PM10
BART alternative emission limitations that we are taking final action to approve in a separate rulemaking that is also being published in this issue of the Federal Register.
DATES: This final rule will be effective April 21, 2021.
ADDRESSES: The EPA has established a docket for this action under Docket No.
