SUPPLEMENTARY INFORMATION:

I. Background

    On September 27, 2016 (81 FR 66332), EPA (``we'') published a rule 
titled ``Promulgation of Air Quality Implementation Plans; State of 
Arkansas; Regional Haze and Interstate Visibility Transport Federal 
Implementation Plan'' (Arkansas Regional Haze FIP or FIP) addressing 
certain requirements of the Regional Haze Rule at 40 CFR 51.308 and the 
CAA regarding interference with other states' programs for visibility 
protection (interstate visibility transport) triggered by the issuance 
of the 1997 ozone National Ambient Air Quality Standards (NAAQS) and 
the 1997 fine particulate matter (PM2.5) NAAQS.\1\
---------------------------------------------------------------------------

    \1\ 81 FR 66332; see also 81 FR 68319 (October 4, 2016) 
(correction).
---------------------------------------------------------------------------

    The Arkansas Department of Environmental Quality (ADEQ) submitted a 
petition to the EPA dated November 22, 2016, seeking reconsideration 
and an administrative stay of specific portions of the final Arkansas 
Regional Haze FIP pursuant to section 307(d)(7)(B) of the CAA and 
section 705 of the Administrative Procedure Act (APA). Similar 
petitions were submitted by Entergy Arkansas Inc., Entergy Mississippi 
Inc., and Entergy Power LLC (collectively Entergy) and the Arkansas 
Electric Cooperative Corporation (AECC), owners of Flint Creek, White 
Bluff, and Independence facilities and the Energy Environmental 
Alliance of Arkansas (EEAA). Under section 307(d)(7)(B) of the CAA, the 
Administrator shall commence a reconsideration proceeding if, in the 
Administrator's judgment, the petitioner raises an objection to a rule 
that was impracticable to raise during the comment period or if the 
grounds for the objection arose after the comment period but within the 
period for judicial review. In either case, the Administrator must also 
conclude that the objection is of central relevance to the outcome of 
the rule. The Administrator may stay the effectiveness of the rule for 
up to 90 days during such reconsideration.
    In a letter dated April 14, 2017, EPA announced the convening of a 
proceeding for reconsideration under section 307(d)(7)(B) of the 
compliance dates for the NOX emission limits for Flint Creek 
Unit 1, White Bluff Units 1 and 2, and Independence Units 1 and 2. 
Further, based on statements by Entergy regarding the limited future 
operations of White Bluff, the EPA also determined to grant 
reconsideration of the SO2 emission limits for Units 1 and 2 
at the facility. We granted reconsideration of these provisions of the 
FIP because the grounds for Petitioners' objections arose after the 
close of the comment period and are of central relevance to the outcome 
of the final rule pursuant to Clean Air Act section 307(d)(7)(B). The 
EPA did not specifically request comment on the 18-month compliance 
dates for NOX controls in the FIP, and reconsideration will 
allow for additional public comment on these issues. In addition, new 
information clarified the intent of Entergy's comments regarding future 
operations at White Bluff and indicated that reconsideration of the 
SO2 best available retrofit technology (BART) emission 
limits based on a shorter remaining useful life is warranted. Finally, 
as we are reconsidering the compliance dates for the NOX 
emission limits at Independence, we are also reconsidering the 
compliance dates for the SO2 emission limits for 
Independence Units 1 and 2 to ensure that the schedule for compliance 
for these emission limits is coordinated. The EPA did not take action 
on the remaining issues in the petitions for reconsideration of the 
Arkansas FIP. A copy of this letter is included in the docket, Docket 
ID No. EPA-R06-OAR-2015-0189.
    We will prepare a notice of proposed rulemaking that will provide 
ADEQ, Entergy, AECC, EEAA and the public an opportunity to comment on 
the issues identified above as well as any other matter we believe will 
benefit from additional comment.

II. Partial Stay of Certain Provisions of the FIP

    The EPA hereby issues a 90 day stay from April 25, 2017 of the 
effectiveness of 40 CFR 52.173(c)(7) and (25) with regards to the 
compliance dates for the NOX emission limits for Flint Creek 
Unit 1, White Bluff Units 1 and 2, and Independence Units 1 and 2, and 
the compliance dates for the SO2 emission limits for White 
Bluff Units 1 and 2 and Independence Units 1 and 2. We are amending the 
Code of Federal Regulations to reflect this stay. This stay does not 
apply to any other provisions of the rule. If the EPA is unable to 
complete final action on reconsideration prior to the conclusion of 
this stay, we will consider granting a further stay of the rule. This 
stay, however, does not alter or extend the ultimate compliance 
timeframes set out in the final FIP. The EPA intends to propose a 
future rulemaking to extend the deadlines to account for the period of 
the stay or to account for another alternative proposal.
