I. What is being addressed in this document?

    On May 14, 2019, the State of Iowa submitted a request to revise 
the State of Iowa's Regional Haze Plan, changing from reliance on the 
Clean Air Interstate Rule (CAIR) to reliance on the Cross State Air 
Pollution Rule (CSAPR) for certain regional haze requirements; removing 
EPA's Federal Implementation Plan (FIP) for reliance on CSAPR for 
certain regional haze requirements, convert EPA's limited approval/
limited disapproval of Iowa's Regional Haze Plan for the first regional 
haze planning period to a full approval; and approve the states' 
submissions addressing the Clean Air Act (CAA or the Act) section 
110(a)(2)(D)(i)(II) provision (prong 4) that prohibit emissions 
activity in one state from interfering with measures to protect 
visibility in another state of Iowa's infrastructure SIP submittals for 
the 2006 Fine Particulate Matter (PM2.5) 2012 Fine 
Particulate Matter (PM2.5), 2010 Nitrogen Dioxide 
(NO2), 2010 Sulfur Dioxide (SO2), 2008 Ozone, and 
2015 Ozone NAAQS. The EPA is finalizing approval of these requests.

II. Have the requirements for approval of a SIP revision been met?

    The state submission has met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The submission also 
satisfied the completeness criteria of 40 CFR part 51, appendix V. The 
state provided the Federal Land Managers the draft rule on February 28, 
2019, providing until April 28, 2019, to receive comments and received 
no comments. The state provided public notice of this SIP revision on 
March 29, 2019, providing until April 29, 2019 to receive comments and 
received no comments. The state held a public hearing on April 29, 2019 
and received no comments. In addition, as explained above, the revision 
meets the substantive SIP requirements of the CAA, including section 
110 and implementing regulations.

III. The EPA's Response to Comments

    The public comment period on the EPA's proposed rule opened August 
22, 2019 the date of its publication in the Federal Register and closed 
on September 23, 2019. During this period, the EPA received one 
comment.
    Comment: EPA must immediately retract this proposal per the 
decision made by the D.C. Circuit Court ruling in Wisconsin, et al v. 
EPA. As the EPA states in [its] now remanded final rule, the CSAPR 
Update addresses both the 2008 and 1997 ozone NAAQS in addition to the 
D.C. Circuit's 2015 remand of the CSAPR rule. ``This CSAPR Update also 
is intended to address the July 28, 2015 remand by the United States 
Court of Appeals for the District of Columbia Circuit of certain 
states' original CSAPR phase 2 ozone season NOX emission 
budgets. In addition, this rule updates the status of certain states' 
outstanding interstate ozone transport obligations with respect to the 
1997 ozone NAAQS, for which the original CSAPR provided a partial 
remedy.'' And so, until EPA addresses the D.C. Circuit's 2019 remand of 
the CSAPR Update rule, EPA can't rely on a CSAPR better than BART 
reasoning until EPA fully [addresses] the remand of CSAPR Update[.]
    Response: The EPA disagrees with this comment. BART-eligible 
electric generating unit (EGU) sources in Iowa may satisfy best 
available retrofit technology (BART) requirements for a given 
visibility pollutant by participating in any of the Cross-State Air 
Pollution Rule (CSAPR) trading programs for that pollutant, as 
authorized by the regional haze rule, 40 CFR 51.308(e)(4). Iowa's 
covered EGUs not only participate in the CSAPR Update ozone season 
NOX trading program for transport of ozone but also the 
CSAPR annual NOX and SO2 trading programs for 
transport of fine particulate matter (PM2.5) under the 1997 
and 2006 national ambient air quality standards (NAAQS) for 
PM2.5. See 40 CFR 52.38(a)(2)(i), 52.39(b); see also CSAPR 
Final Rule, 76 FR 48208-76 FR 48213 (August 8, 2011). Thus, regardless 
of whether Iowa's EGUs participate in the CSAPR Update ozone season 
NOX trading program, their participation in the CSAPR annual 
NOX trading program would continue to be sufficient to 
satisfy BART requirements for NOX as a visibility pollutant.
    EPA initially determined that participation in either ozone-season 
or annual NOX trading programs would satisfy BART for 
NOX in concluding that participation in the trading programs 
established under CAIR, the predecessor to CSAPR, could serve as BART 
alternatives. See BART Guidelines Final Rule, 70 FR 39104-70 FR 39143 
(July 6, 2005); see also 71 FR 60612-71 FR 60623 (October 13, 2006) 
(clarifying EPA's 2005 determination that ``participation in either the 
annual or seasonal CAIR NOX cap-and-trade program is a 
necessary condition for relying on EPA's determination that States can 
substitute CAIR for BART for NOX''). When CSAPR replaced 
CAIR, EPA conducted a BART-alternative analysis similar to the BART-
alternative analysis conducted for CAIR, and again specifically 
assessed whether participation in either the CSAPR ozone-season 
NOX trading program or the CSAPR annual NOX 
trading program would be sufficient to satisfy the BART-alternative 
analysis for NOX; EPA again concluded that either would 
suffice. See 77 FR 33642 at 77 FR 33650-77 FR 33651 (June 7, 2012). 
Thus, the current text of the regional haze rule continues to provide 
that a state ``subject to a trading program [under CSAPR] need not 
require BART-eligible fossil fuel fired steam electric plants in the 
State to install, operate, and maintain BART for the pollutant covered 
by such trading program in the State,'' 40 CFR 51.308(e)(4) (emphasis 
added). This provision recognizes that participation in either the 
ozone-season or annual NOX trading program would satisfy 
BART. So long as Iowa's BART-eligible fossil-fuel fired EGUs are 
subject to CSAPR's annual NOX trading program, their 
participation in the ozone-season NOX trading program--or 
the status of the CSAPR Update ozone-season NOX program more 
generally--is not relevant for determining that these sources' BART 
obligations for NOX are satisfied.
    Further, if it so chose, Iowa could continue to rely on the CSAPR 
Update (81 FR 74504, October 26, 2016) ozone-season NOX 
trading program to satisfy best available retrofit technology (BART) 
requirements for Iowa's BART-eligible electric generating units (EGUs), 
as authorized by 40 CFR 51.308(e)(4). The court's decision in Wisconsin 
v. EPA, No. 16-1406 (D.C. Cir. September 13, 2019), did not vacate the 
CSAPR Update, and that rule, including Iowa's ozone-season 
NOX budget, remains in place. The Wisconsin decision upheld 
the CSAPR Update rule in most respects, but held the rule was 
inconsistent with the CAA to the extent it failed to require upwind 
states to eliminate their significant contributions to downwind ozone 
problems in accordance with the downwind areas' ozone attainment 
deadline. Wisconsin, Slip Op. 13. The court remanded the Update rule 
but expressly declined to vacate it in order to avoid ``substantial 
disruption'' and in recognition of the potential ``harm to the public 
health and environment'' vacatur could cause. Id. at 59.
    At this time, the CSAPR Update rule remains in operation, and it is 
entirely speculative--not to mention improbable

[[Page 66077]]

in light of the court's reasoning--that on remand, the CSAPR Update's 
ozone-season NOX budget for any state would become less 
stringent, much less in a way that could impact EPA's analysis of the 
CSAPR program as a BART-alternative.
    Finally, the commenter states that the CSAPR Update rule addressed 
not only the 2008 ozone NAAQS but also the remand of some of the 
original CSAPR ozone-season NOX budgets for the 1997 ozone 
NAAQS in EME Homer City Generation v. EPA, 795 F.3d 118 (D.C. Cir. 
2015). See CSAPR Update Final Rule, 81 FR 74504 at 81 FR 74507 (October 
26, 2016). The relevance of this observation to the present action is 
not clear. Iowa's was not one of the original CSAPR ozone-season 
NOX budgets remanded due to potential over-control in EME 
Homer City, see 795 F.3d 118, 138. Further, in the Wisconsin case 
reviewing the CSAPR Update rule, no party challenged the portion of 
that rule resolving the remanded budgets from EME Homer City, and there 
is no reason to believe those determinations would be revisited or 
reopened on the remand in Wisconsin.
    For all these reasons, the Wisconsin decision and remand of the 
CSAPR Update does not alter or affect Iowa's ability to continue to 
rely on participation in CSAPR trading programs to satisfy BART for 
NOX and SO2 for its BART-eligible sources covered 
by the CSAPR trading programs.

IV. What action is the EPA taking?

    The EPA is amending the Iowa SIP to relying on CSAPR for certain 
Regional Haze requirements in accordance with the CAA and the Regional 
Haze Rule (40 CFR 51.308(e)(4)); withdrawing the FIP relying on CSAPR 
to satisfy those requirements; fully approving Iowa's regional haze SIP 
for the first planning period; and approving the prong 4 portions for 
each of the six NAAQS identified above.

V. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was 
therefore not submitted to the Office of Management and Budget (OMB) 
for review.

B. Executive Order 13771: Reducing Regulations and Controlling 
Regulatory Costs

    This action is not an Executive Order 13771 regulatory action 
because this action is not significant under Executive Order 12866.

C. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the PRA. This action approves state plans that do not impose any 
information collection.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. This 
action will not impose any requirements on small entities. This action 
approves state plans that rely on no new requirements on any entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538, 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.

F. 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.

G. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have tribal implications, as specified in 
Executive Order 13175. It will not have substantial direct effects on 
tribal governments. There are no Indian reservation lands in Missouri. 
Thus, Executive Order 13175 does not apply to this rule.

H. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045 because it approves a state program and approves 
a state action implementing a federal standard.

I. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211, because it is 
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act

    This rulemaking does not involve technical standards.

K. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    EPA believes that this action does not have disproportionately high 
and adverse human health or environmental effects on minority 
populations, low-income populations, and/or indigenous peoples, as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994).

L. Determination Under Section 307(d)

    Pursuant to CAA section 307(d)(1)(B), this action is subject to the 
requirements of CAA section 307(d), as it revises a FIP under CAA 
section 110(c).

M. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule 
report to each House of the Congress and to the Comptroller General of 
the United States. This action [is/is not] a ``major rule'' as defined 
by 5 U.S.C. 804(2).

N. Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by February 3, 2020. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed and shall not postpone the effectiveness of such rule or 
action. This action, Revisions to Regional Haze Plan and Visibility 
Requirements in Infrastructure State Implementation Plans for the 2006 
PM2.5, 2012 PM2.5, 2010 NO2, 2010 
SO2, 2008 Ozone, and 2015 Ozone NAAQS may not be challenged 
later in

[[Page 66078]]

proceedings to enforce its requirements. See CAA section 307(b)(2).
