proposed approval of Arkansas request to withdraw from the approved SIP the previously approved PM10 BART limit for Power Boiler No. 1; and proposed withdrawal of the remaining portion of the Arkansas FIP, which consists of provisions addressing the regional haze requirements for the Domtar Ashdown Mill. The EPA also proposed to approve the portions of the August 8, 2018
Arkansas Regional Haze Phase II SIP
revision and the October 4, 2019
Arkansas 2015 Ozone O3 NAAQS
Interstate Transport SIP revision addressing the visibility transport provisions required under CAA section 110a2DiII for the following NAAQS: The 2006 24-hour PM2.5
NAAQS; the 2012 annual PM2.5
NAAQS; the 2008 and 2015 eight-hour O3 NAAQS; the 2010 one-hour NO2
NAAQS; and the 2010 one-hour SO2
NAAQS. In a final action being published separately in this issue of the Federal Register, we are taking final action to approve the Arkansas Regional Phase III SIP revision and the visibility transport portions of the Arkansas Regional Haze Phase II SIP revision and the Arkansas 2015 O3 NAAQS Interstate Transport SIP revision.
The background for this final rule and the separate final action also being published in this issue of the Federal Register that approves the Arkansas Regional Haze Phase III SIP revision and portions of the Arkansas Regional Haze Phase II SIP revision and the Arkansas 2015 O3 NAAQS Interstate Transport SIP revision is also discussed in detail in our March 16, 2020 proposed approval.13 The comment period was open for thirty days and closed on April 15, 2020. We received a total of two sets of public comments concerning our proposed action. The comments are included in the publicly posted docket associated with the rulemaking EPA
R06OAR20150189, available at https www.regulations.gov.
II. Final Action We are withdrawing the remaining portion of the Arkansas Regional Haze FIP that we promulgated on September 27, 2016, found at 40 CFR 52.173c.
Specifically, we are withdrawing provisions addressing applicability and definitions of the FIP; SO2 and NOX
emission limits for Power Boiler No. 1;
SO2, NOX, and PM emission limits for Power Boiler No. 2; BART compliance dates; compliance determination requirements and reporting and recordkeeping requirements associated with the BART emission limits; and provisions addressing equipment
operations and enforcement. We are removing these SO2, NOX, and PM
emission limitations and associated requirements for Power Boilers No. 1
and 2 found at 40 CFR 52.173c, and as of the effective date of this final rule these requirements will no longer apply to these units. Since we are withdrawing the text from paragraph c under 40 CFR 52.173, we are also reserving paragraph c so as to not disturb the numbering of existing paragraphs d through g under 40 CFR
52.173.
As explained in our March 16, 2020
proposal,14 this action is based on our separate action being published in this issue of the Federal Register approving the Arkansas Regional Haze Phase III
SIP revision submitted to us on August 13, 2019. In that separate action, EPA is making the determination that the Arkansas Regional Haze Phase III SIP
revision is approvable because the plans provisions meet the applicable requirements of the CAA and EPA
implementing regulations. EPA is finalizing this action under section 110
and part C of the Act.
III. Response to Comments We received two comment letters concerning our proposed action, which included our proposed approval of the Phase III SIP revision, proposed approval of the visibility transport portions of the Arkansas Regional Haze Phase II SIP revision and the Arkansas 2015 O3 NAAQS Interstate Transport SIP revision, and proposed withdrawal of the remaining FIP provisions. EPA
did not receive any comments specifically addressing our proposed withdrawal of the remaining FIP
provisions; rather, the comments addressed EPAs proposed approval of the SIP provisions that would replace the FIP. Therefore, we have responded to all relevant comments in response to our proposed action in the separate, final notice being published in this issue of the Federal Register that approves the Arkansas Regional Haze Phase III SIP revision.15

A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review 13563
This action is exempt from review by the Office of Management and Budget OMB because it will withdraw a FIP
containing source-specific SO2, NOX, and PM emission limits for two individually identified units at one facility in Arkansas and is therefore not a rule of general applicability and not a significant regulatory action.
B. Paperwork Reduction Act This action does not impose an information collection burden under the provisions of the PRA. Burden is defined at 5 CFR 1320.3b. This final rule withdraws a FIP containing sourcespecific SO2, NOX, and PM emission limits for two individually identified units at one facility in Arkansas.
C. Regulatory Flexibility Act I certify that this final action will not have a significant economic impact on a substantial number of small entities under the RFA. This final action will not impose any requirements on small entities. This final action withdraws a FIP containing source-specific SO2, NOX, and PM emission limits that apply to two individually identified units at one facility in Arkansas.
D. Unfunded Mandates Reform Act This action does not contain any unfunded mandate as described in UMRA, 2 U.S.C. 15311538, and does not significantly or uniquely affect small governments. This action does not impose additional requirements beyond those imposed by state law.
Accordingly, no additional costs to State, local, or tribal governments, or to the private sector, will result from this action.
E. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government.
F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have tribal implications, as specified in Executive Order 13175, because the FIP we are withdrawing does not apply on any Indian reservation land or in any other area where the EPA or an Indian tribe has demonstrated that a tribe has
