40 CFR Part 52

[EPA-R07-OAR-2014-0365; FRL-9931-72-Region 7]

Approval and Promulgation of Air Quality Implementation Plans; 
Iowa; Regional Haze Five-Year Progress Report State Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; supplemental.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is issuing a 
supplement to its proposed approval of a State Implementation Plan 
(SIP) revision submitted by the State of Iowa (Iowa) through the Iowa 
Department of Natural Resources (IDNR). Iowa's SIP revision addresses 
requirements of the Clean Air Act (CAA) and EPA's rules that require 
states to submit periodic reports describing progress toward reasonable 
progress goals established for regional haze and a determination of the 
adequacy of the state's existing implementation plan addressing 
regional haze (region haze SIP). EPA's proposed approval of Iowa's 
periodic report on progress toward reasonable progress goals and 
determination of adequacy of the state's regional haze SIP published in 
the Federal Register on July 3, 2014. This supplemental proposal 
addresses the potential effects on our proposed approval from the April 
29, 2014, decision of the United States Supreme Court (Supreme Court) 
remanding to the United States Court of Appeals for the District of 
Columbia Circuit (D.C. Circuit) EPA's Cross-State Air Pollution Rule 
(CSAPR) for further proceedings and the D.C. Circuit's decision to lift 
the stay of CSAPR.

DATES: Comments must be received on or before August 31, 2015.

I. Background

    EPA previously proposed to approve a SIP revision by Iowa reporting 
on progress made in the first implementation period toward meeting the 
reasonable progress goals for Class I areas outside Iowa that are 
affected by emissions from Iowa's sources.\1\ 79 FR 37976 (July 3, 
2014). In its submittal, Iowa determined its existing regional haze SIP 
requires no substantive revision to achieve the established regional 
haze visibility improvement and emissions reduction goals for 2018.
---------------------------------------------------------------------------

    \1\ Iowa does not have any Class I areas within its borders. 
Iowa states in the progress report SIP that Iowa sources were 
identified, through an area of influence modeling analysis based on 
back trajectories, as potentially impacting four Class I areas in 
two nearby states: Boundary Waters Canoe Area Wilderness and 
Voyagers National Park in Minnesota, and Isle Royale National Park 
and Seney Wilderness Area in Michigan.
---------------------------------------------------------------------------

    States are required to submit a progress report in the form of a 
SIP revision every five years that evaluates progress toward the 
reasonable progress goals for each mandatory Class I area within the 
state and in each mandatory Class I area outside the state which may be 
affected by emissions from within the state. See 40 CFR 51.308(g). In 
addition, the provisions under 40 CFR 51.308(h) require states to 
submit, at the same time as the 40 CFR 51.308(g) progress report, a 
determination of the adequacy of the state's existing regional haze 
SIP. The first progress report SIP revision is due five years after 
submittal of the initial regional haze SIP. IDNR submitted its regional 
haze SIP on March 25, 2008, and submitted its progress report SIP 
revision on July 16, 2013. EPA proposed to find that the progress 
report SIP revision satisfied the requirements of 40 CFR 51.308(g) and 
(h) in a notice of proposed rulemaking (NPR) published in 2014. 79 FR 
37976. This action supplements EPA's prior NPR by more fully explaining 
and soliciting comment on the basis for our proposed approval.

II. Summary of Iowa's Progress Report SIP Revision and the NPR

    On July 16, 2013, Iowa submitted a SIP revision describing the 
progress made toward the RPGs of Class I areas outside Iowa that are 
affected by emissions from Iowa's sources in accordance with 
requirements in the Regional Haze Rule.\2\ This progress report SIP 
also included an assessment of whether Iowa's existing regional haze 
SIP is sufficient to allow nearby states with Class I areas to achieve 
the reasonable progress goals by the end of the first planning period.
---------------------------------------------------------------------------

    \2\ EPA promulgated a rule to address regional haze on July 1, 
1999 (64 FR 35713) known as the Regional Haze Rule. The Regional 
Haze Rule revised the existing visibility regulations to integrate 
into the regulation provisions addressing regional haze impairment 
and established a comprehensive visibility protection program for 
Class I areas. See 40 CFR 51.308 and 51.309.
---------------------------------------------------------------------------

    The provisions in 40 CFR 51.308(g) require a progress report SIP to 
address seven elements. In the NPR, EPA proposed to approve the SIP as 
adequately addressing each element under 40 CFR 51.308(g). The seven 
elements and EPA's proposed conclusions in the NPR are briefly 
summarized below.
    The provisions in 40 CFR 51.308(g) require progress report SIPs to 
include a description of the status of measures in the regional haze 
implementation plan; a summary of the emissions reductions achieved; an 
assessment of the visibility conditions for each Class I area in the 
state; an analysis of the changes in emissions from sources and 
activities within the state; an assessment of any significant changes 
in anthropogenic emissions within or outside the state that have 
limited or impeded visibility improvement progress in Class I areas 
impacted by the state's sources; an assessment of the sufficiency of 
the regional haze implementation plan to enable States to meet 
reasonable progress goals; and a review of the state's visibility 
monitoring strategy. As explained in detail in the NPR, EPA proposed 
the Iowa's progress report SIP addressed each element and therefore 
satisfied the requirements under 40 CFR 51.308(g).
    In addition, pursuant to 40 CFR 51.308(h), states are required to 
submit, at the same time as the progress report SIP revision, a 
determination of the adequacy of their existing regional haze SIP and 
to take one of four possible actions based on information in the 
progress report. In its progress report SIP, Iowa determined that its 
regional haze SIP is sufficient to meet its obligations related to the 
reasonable progress goals for Class I areas affected by Iowa's sources. 
The State accordingly provided EPA with a negative declaration that 
further revision of the existing regional haze implementation plan was 
not needed at this time. See 40 CFR 51.308(h)(1). As explained in 
detail in the NPR, EPA proposed to determine that Iowa had adequately 
addressed 40 CFR 51.308(h) because the visibility data trends at the 
Class I areas impacted by Iowa's sources and the emissions trends of 
the largest emitters in Iowa of visibility-impairing pollutants both 
indicate that the reasonable progress goals for 2018 for these areas 
will be met or exceeded. Therefore, in our NPR, EPA proposed to approve 
Iowa's progress report SIP as meeting the requirements of 40 CFR 
51.308(g) and (h).

III. Impact of CAIR and CSAPR on Iowa's Progress Report

    Decisions by the Courts regarding EPA rules addressing the 
interstate transport of pollutants have had a substantial impact on 
EPA's review of the regional haze SIPs of many states. In 2005, EPA 
issued regulations allowing states to rely on the Clean Air Interstate 
Rule (CAIR) to meet certain requirements of the Regional Haze Rule. See 
70 FR 39104 (July 6, 2005).\3\ A number of states, including Iowa, 
submitted regional haze SIPs consistent with these regulatory 
provisions. CAIR, however, was remanded to EPA in 2008, North Carolina 
v. EPA, 550 F.3d 1176, 1178 (D.C. Cir. 2008), and replaced by CSAPR.\4\ 
76 FR 48208 (August 8, 2011). Implementation of CSAPR was scheduled to 
begin on January 1, 2012, when CSAPR would have superseded the CAIR 
program. However, numerous parties filed petitions for review of CSAPR, 
and at the end of 2011, the DC Circuit issued an order staying CSAPR 
pending resolution of the petitions and directing EPA to continue to 
administer CAIR. Order of December 30, 2011, in EME Homer City 
Generation, L.P. v. EPA, D.C. Cir. No. 11-1302.
---------------------------------------------------------------------------

    \3\ CAIR required certain states like Iowa to reduce emissions 
of sulfur dioxide (SO2) and nitrogen oxides 
(NOX) that significantly contribute to downwind 
nonattainment of the 1997 National Ambient Air Quality Standard 
(NAAQS) for fine particulate matter (PM2.5) and ozone. 
See 70 FR 25162 (May 12, 2005).
    \4\ CSAPR was issued by EPA to replace CAIR and to help states 
reduce air pollution and attain CAA standards. See 76 FR 48208 
(August 8, 2011) (final rule). CSAPR requires substantial reductions 
of SO2 and NOX emissions from EGUs in 28 
states in the Eastern United States that significantly contribute to 
downwind nonattainment of the 1997 PM2.5 and ozone NAAQS 
and 2006 PM2.5 NAAQS.
---------------------------------------------------------------------------

    EPA finalized a limited approval of Iowa's regional haze SIP on 
June 26, 2012. 77 FR 38006. In a separate action, published on June 7, 
2012, EPA finalized a limited disapproval of the Iowa regional haze SIP 
because of the state's reliance on CAIR to meet certain regional haze 
requirements, and issued a Federal Implementation Plan (FIP) to address 
the deficiencies identified in the limited disapproval of Iowa and 
other states' regional haze plans. 77 FR 33642 (June 7, 2012). In our 
FIP, we relied on CSAPR to meet certain regional haze requirements 
notwithstanding that it was stayed at the time. As we explained, the 
determination that CSAPR will provide for greater reasonable progress 
than BART is based on a forward-looking projection of emissions and any 
year up until 2018 would have been an

[[Page 45633]]

acceptable point of comparison. Id. at 33647. When we issued this FIP, 
we anticipated that the requirements of CSAPR would be implemented 
prior to 2018. Id. Following these EPA actions, however, the DC Circuit 
issued a decision in EME Homer City Generation, L.P. v. EPA, 696 F.3d 7 
(D.C. Cir. 2012), vacating CSAPR and ordering EPA to continue 
administering CAIR pending the promulgation of a valid replacement. On 
April 29, 2014, the Supreme Court reversed the DC Circuit's decision on 
CSAPR and remanded the case to the DC Circuit for further proceedings. 
EPA v. EME Homer City Generation, L.P., 134 S. Ct. 1584 (2014). After 
the Supreme Court decision, EPA filed a motion to lift the stay on 
CSAPR and asked the DC Circuit to toll CSAPR's compliance deadlines by 
three years, so that the Phase 1 emissions budgets apply in 2015 and 
2016 (instead of 2012 and 2013), and the Phase 2 emissions budgets 
apply in 2017 and beyond (instead of 2014 and beyond). On October 23, 
2014, the DC Circuit granted EPA's motion. Order of October 23, 2014, 
in EME Homer City Generation, L.P. v. EPA, D.C. Cir. No. 11-1302. EPA 
issued an interim final rule to clarify how EPA will implement CSAPR 
consistent with the DC Circuit's order granting EPA's motion requesting 
lifting the stay and tolling the rule's deadlines. 79 FR 71663 
(December 3, 2014) (interim final rulemaking).\5\
---------------------------------------------------------------------------

    \5\ Subsequent to the interim final rulemaking, EPA began 
implementation of CSAPR on January 1, 2015.
---------------------------------------------------------------------------

    Throughout the litigation described above, EPA has continued to 
implement CAIR. Thus, at the time that Iowa submitted its progress 
report SIP revision, CAIR was in effect, and the State included an 
assessment of the emission reductions from the implementation of CAIR 
in its report. The progress report discussed the status of the 
litigation concerning CAIR and CSAPR, but because CSAPR was not at that 
time in effect, Iowa did not take emissions reductions from CSAPR into 
account in assessing its regional haze implementation plan. For the 
same reason, in our NPR, EPA did not assess at that time the impact of 
CSAPR or our FIP on the ability of Iowa and its neighbors to meet their 
reasonable progress goals.
    The purpose of this supplemental proposal is to seek comment on the 
effect of the D.C. Circuit's October 23, 2014, order and the effect of 
the status of CAIR and CSAPR on our assessment of Iowa's progress 
report SIP and our determination that its existing implementation plan 
need not be revised at this time.
    Iowa appropriately took CAIR into account in its progress report 
SIP in describing the status of the implementation of measures included 
in its regional haze SIP and in summarizing the emissions reductions 
achieved. CAIR was in effect during the 2008-2013 period addressed by 
Iowa's progress report. EPA approved Iowa's regulations implementing 
CAIR as part of the Iowa SIP in 2008, 73 FR 20177 (April 15, 2008), and 
neither Iowa nor EPA has taken any action to remove CAIR from the Iowa 
SIP. See 40 CFR 52.2520(c). Therefore, Iowa appropriately evaluated and 
relied on CAIR reductions to demonstrate the State's progress toward 
meeting its emission reductions.\6\ The State's progress report also 
demonstrated Class I areas in other states impacted by Iowa sources 
were on track to meet their reasonable progress goals as discussed in 
the NPR. EPA's intention in requiring the progress reports pursuant to 
40 CFR 51.308(g) was to ensure that emission management measures in the 
regional haze SIPs are being implemented on schedule and that 
visibility improvement appears to be consistent with the reasonable 
progress goals. (64 FR 35713, July 1, 1999). As the D.C. Circuit only 
recently lifted the stay on CSAPR, CAIR was in effect in Iowa through 
2014, providing the emission reductions relied upon in Iowa's regional 
haze SIP. Thus, Iowa appropriately took into account CAIR reductions in 
assessing the implementation of measures in the regional haze SIP for 
the 2008-2013 timeframe, and EPA believes that it is appropriate to 
rely on CAIR emission reductions for purposes of assessing the adequacy 
of Iowa's progress report demonstrating progress up to the end of 2014 
as CAIR remained effective until that date, pursuant to 40 CFR 
51.308(g) and (h).
---------------------------------------------------------------------------

    \6\ EPA discussed in the NPR the significance of reductions in 
SO2 and NOX as Iowa and the Central Regional 
Air Planning Association (CENRAP) identified SO2 and 
NOX as the largest contributor pollutants to visibility 
impairment at the Class I areas affected by Iowa's sources, 
specifically, and in the CENRAP region generally.
---------------------------------------------------------------------------

    In addition, EPA believes reliance upon CAIR reductions to show 
Iowa's progress toward meeting emissions reductions from 2008-2013 is 
consistent with our prior actions. During the continued implementation 
of CAIR per the direction of the D.C. Circuit through October 2014, EPA 
has approved redesignations of areas to attainment of the 1997 
PM2.5 NAAQS in which states relied on CAIR as an 
``enforceable measure.'' See 77 FR 76415 (December 28, 2012) 
(redesignation of Huntington-Ashland, West Virginia) and 80 FR 9207 
(February 20, 2015) (redesignation of St. Louis, Missouri). While EPA 
did previously state in a rulemaking action on the Florida regional 
haze SIP that a five year progress report may be the appropriate time 
to address changes, if necessary, for reasonable progress goal 
demonstrations and long term strategies, EPA does not believe such 
changes were necessary for Iowa's progress report SIP. See generally 77 
FR 73369, 77 FR 73371 (December 10, 2012) (proposed action on Florida 
haze SIP). In this action, EPA is proposing that the remanded status of 
CAIR and the implementation of its replacement CSAPR at this time do 
not impact the adequacy of the Iowa regional haze SIP to address 
reasonable progress from 2008 through 2013 or even through 2014 to meet 
requirements in 40 CFR 51.308(g) and (h) because CAIR was implemented 
during the time period evaluated by Iowa for its progress report.
    EPA's December 3, 2014, interim final rule sunsets CAIR compliance 
requirements on a schedule coordinated with the implementation of CSAPR 
compliance requirements. 79 FR at 71655. As noted above, EPA's June 7, 
2012, FIP replaced Iowa's reliance upon CAIR for regional haze 
requirements with reliance on CSAPR to meet those requirements for the 
long-term. Because CSAPR should result in greater emissions reductions 
of SO2 and NOX than CAIR regionally, EPA 
anticipates Iowa to maintain and continue its progress toward their 
projected emissions for 2018. See generally 76 FR 48208 (promulgating 
CSAPR). Although the implementation of CSAPR was tolled for three 
years, the rule is now being implemented, and CSAPR budgets of 
SO2 and NOX from EGUs in Iowa are the same as 
assumed by EPA when it issued the CSAPR FIP for Iowa in June 2012. See 
76 FR 48208 (CSAPR promulgation) and 77 FR 33642 (limited disapproval 
of Iowa regional haze SIP and FIP for Iowa for certain regional haze 
requirements).
    At the present time, the requirements of CSAPR apply to sources in 
Iowa under the terms of a FIP, because Iowa to date has not 
incorporated the CSAPR requirements into its SIP. The Regional Haze 
Rule requires an assessment of whether the current ``implementation 
plan'' is sufficient to enable the states to meet all established 
reasonable progress goals. 40 CFR 51.308(g)(6). The term 
``implementation plan'' is defined for purposes of the Regional Haze 
Rule to mean ``any [SIP], [FIP], or Tribal Implementation Plan.'' 40 
CFR 51.301.

[[Page 45634]]

EPA is, therefore, proposing to determine that we may consider measures 
in any issued FIP as well as those in a state's regional haze SIP in 
assessing the adequacy of the ``existing implementation plan'' under 40 
CFR 51.308(g)(6) and (h). Because CSAPR will ensure the control of 
SO2 and NOX emissions reductions relied upon by 
Iowa and other states in setting their reasonable progress goals 
beginning in January 2015 at least through the remainder of the first 
implementation period in 2018, EPA is proposing to approve Iowa's 
finding that there is no need for revision of the existing 
implementation plan for Iowa to achieve the reasonable progress goals 
for the Class I areas in nearby states impacted by Iowa sources.
    We note that the Regional Haze Rule provides for periodic 
evaluation and assessment of a state's reasonable progress toward 
achieving the national goal of natural visibility conditions by 2064 
for CAA section 169A(b). The regional haze regulations at 40 CFR 51.308 
required states to submit initial SIPs in 2007 providing for reasonable 
progress toward the national goal for the first implementation period 
from 2008 through 2018. 40 CFR 51.308(b). Pursuant to 40 CFR 51.308(f), 
SIP revisions reassessing each state's reasonable progress toward the 
national goal are due every the years after that time. For such 
subsequent regional haze SIPs, 40 CFR 51.308(f) requires each state to 
reassess its reasonable progress and all the elements of its regional 
haze SIP required by 40 CFR 51.308(d), taking into account improvements 
in monitors and control technology, assessing the state's actual 
progress and effectiveness of its long term strategy, and revising 
reasonable progress goals as necessary. 40 CFR 51.308(f)(1)-(3). 
Therefore, Iowa has the opportunity to reassess its emissions trends 
and the adequacy of its regional haze SIP, including its reliance upon 
CSAPR for emission reductions from EGUs, when it prepares and submits 
its second regional haze SIP to cover the implementation period from 
2018 through 2028. As discussed in the NPR and in Iowa's progress 
report, emissions of SO2 and NOX from EGUs are 
far below original projections for 2018. In addition, the visibility 
data provided by Iowa show the Class I areas impacted by Iowa sources 
are all currently on track to achieve their projected emissions 
reductions. EPA is seeking comment only on the issues raised in this 
supplemental proposal and is not reopening for comment other issues 
addressed in its prior proposal.

IV. Summary of Reproposal

    In summary, EPA is proposing to approve Iowa's progress report SIP 
revision. EPA solicits comments on this supplemental proposal, with 
respect to only the specific issues raised in this action. EPA is not 
reopening the comment period on any other aspect of the July 3, 2014, 
NPR, as an adequate opportunity to comment on those issues has already 
been provided. The purpose of this supplemental proposal is limited to 
review of the Iowa progress report in light of the Supreme Court's 
decision in EME Homer City and the D.C. Circuit's recent Order lifting 
the stay on CSAPR. This supplemental proposal reflects EPA's desire for 
public input into how it should proceed in light of those decisions 
when acting on the pending progress report, in particular the 
requirements that the State assess whether the current implementation 
plan is sufficient to ensure that reasonable progress goals are met. 40 
CFR 51.308(g)(6) and (h).\7\
---------------------------------------------------------------------------

    \7\ EPA previously determined that CSAPR (like CAIR before it) 
was ``better than BART'' because it would achieve greater reasonable 
progress toward the national goal than would source-specific BART. 
77 FR 33642 (June 7, 2012). EPA is not taking comment in this 
supplemental proposal on whether the Iowa implementation plan meets 
the BART requirements or whether CSAPR is an alternative measure to 
source-specific BART in accordance with 40 CFR 52.301(e)(2).
---------------------------------------------------------------------------

V. Statutory and Executive Order Reviews

    In this action, EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, EPA is proposing to incorporate by 
reference the Iowa Nonregulatory Provisions described in the proposed 
amendments to 40 CFR part 52 set forth below. EPA has made, and will 
continue to make, these documents generally available electronically 
through www.regulations.gov and/or in hard copy at the appropriate EPA 
office (see the ADDRESSES section of this preamble for more 
information).
    Under the Clean Air Act (CAA), the Administrator is required to 
approve a SIP submission that complies with the provisions of the Act 
and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the CAA. Accordingly, 
this action merely approves state law as meeting Federal requirements 
and does not impose additional requirements beyond those imposed by 
state law. For that reason, this action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where EPA or an Indian tribe has demonstrated that a 
tribe has jurisdiction. In those areas of Indian country, the rule does 
not have tribal implications and will not impose substantial direct 
costs on tribal governments or preempt tribal law as specified by 
Executive Order 13175 (65 FR 67249, November 9, 2000).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this proposed action 
and other required information to the U.S. Senate, the U.S. House of

[[Page 45635]]

Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This proposed action is not a ``major rule'' as defined by 5 
U.S.C. 804(2).
    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 September 29, 2015. Filing a petition for 
reconsideration by the Administrator of this proposed rule does not 
affect the finality of this rulemaking 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 
future rule or action. This proposed action may not be challenged later 
in proceedings to enforce its requirements. (See section 307(b)(2).)
