Revisions to Federal Implementation Plans To Reduce Interstate 
Transport of Fine Particulate Matter and Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is taking direct final action on additional revisions to 
the final Transport Rule (Federal Implementation Plans: Interstate 
Transport of Fine Particulate Matter and Ozone and Correction of SIP 
Approvals published August 8, 2011). In the proposed Revisions to 
Federal Implementation Plans To Reduce Interstate Transport of Fine 
Particulate Matter and Ozone, published October 14, 2011, EPA sought 
additional comment on unit-level operational information similar to the 
information supporting the proposed revisions, which specifically 
addressed post-combustion pollution control equipment and immediate-
term operational requirements necessitating non-economic generation 
based on verifiable data. Based on comments received, EPA is finalizing 
adjustments that result in revisions to 2012 and 2014 state budgets in 
Arkansas, Georgia, Indiana, Kansas, Louisiana, Mississippi, Missouri, 
New York, Nebraska, Ohio, Oklahoma, South Carolina, and Texas, and 
revisions to new unit set-asides in Arkansas, Louisiana, and 
Missouri.\1\
---------------------------------------------------------------------------

    \1\ Throughout this preamble, EPA refers to a state budget for 
2012 and 2013 as a ``2012'' state budget and refers to a state 
budget for 2014 and thereafter as a ``2014'' state budget. 
Therefore, any revision of a 2012 state budget would apply to the 
state budget for 2012 and 2013, and any revision of a 2014 state 
budget would apply to the state budget for 2014 and thereafter.

DATES: This rule is effective on May 21, 2012 without further notice, 
unless EPA receives significant adverse comments by March 22, 2012. If 
we receive such comments, we will publish a timely withdrawal in the 
---------------------------------------------------------------------------
Federal Register.

I. Detailed Discussion of Corresponding Rule Revisions

    EPA has determined that the following additional corrections are 
needed to the August 8, 2011 final Transport Rule, as a result of 
comments received on the proposed rule, Revisions to Federal 
Implementation Plans to Reduce Interstate Transport of Fine Particulate 
Matter and Ozone (76 FR 63860, October 14, 2011) (Revisions Rule). In 
that proposed rule, EPA took comment on several similar corrections and 
demonstrated a consistent methodology for calculating those 
corrections. EPA received no comments opposing the proposal to make 
these corrections to state budgets and new unit set-asides, and EPA 
received very few comments addressing the manner in which the 
corrections were quantified, to which EPA responded in the final 
revisions rule. EPA has calculated the corrections in this rulemaking 
in a fully consistent manner with the approach developed through public 
comment on the proposed and finalized revisions rule. See the ``Final 
Revisions Rule State Budgets and New Unit Set-Asides'' Technical 
Support Document (TSD) in the docket for this rulemaking for a 
quantitative demonstration of these revisions. For quantitative 
assessments of the relationship between final revisions to the 
Transport Rule and the original analysis, also see ``Final Revisions 
Rule Significant Contribution Assessment'' TSD in the docket for this 
rulemaking. The ``Final Revisions Rule Unit-Level Allocations under the 
FIPs,'' also in the docket for this rulemaking, present unit-level 
allocations under the FIPs.
    (1) Revise the Arkansas ozone season NOX budgets for 
2012 and 2014 and correct the ozone season new unit set-aside budget 
for an omitted planned facility.
    EPA is increasing the Arkansas 2012 and 2014 ozone-season 
NOX budget based upon comments received that demonstrate 
that the McClellan plant is in an out-of-merit-order dispatch area with 
conditions likely to necessitate what would otherwise be non-economic 
generation.\2\
---------------------------------------------------------------------------

    \2\ In the proposed revisions rule, EPA characterized an out-of-
merit-order dispatch area as one in which ``units * * * are 
frequently dispatched out of regional economic order as a result of 
short-run limitations on the ability to meet local electricity 
demand with generation from outside the area.'' (76 FR 63865)
---------------------------------------------------------------------------

    EPA re-calculated the emissions from the McClellan plant with non-
economic generation to account for the input assumption changes. These 
calculations yield increases to the Arkansas 2012 and 2014 state 
budgets for ozone-season NOX of 73 tons. Comments on the 
revisions rule identified Turk Unit 1 as commencing commercial 
operation on or after January 1, 2010, qualifying it as a new unit 
under the final Transport Rule's unit-level allocation methodology (76 
FR 48290); however, the final Transport Rule erroneously omitted this 
unit's projected emissions from the calculation of Arkansas' ozone-
season NOX new unit set-aside. EPA is therefore revising the 
portion of the Arkansas ozone-season budget dedicated to the state's 
new unit set-aside account so that it takes into account this unit's 
projected emissions, consistent with the new unit set-aside methodology 
in the final Transport Rule. EPA is only applying this revision for 
2014 and beyond, because the Agency has already recorded (i.e., 
distributed) allowances under the Arkansas state budget for the 2012 
and 2013 control periods. Turk Unit 1 remains eligible to request 
allowance allocation from the new unit set-asides for any control 
period under the program. This revision yields an ozone-season 
NOX new unit set-aside of 8 percent for 2014 and beyond for 
Arkansas. This revision to the Arkansas new unit set-aside necessitates 
changes to allowance allocations to existing units in 2014 and beyond.
    (2) Revise the Georgia SO2, annual NOX, and 
ozone season NOX budgets for 2014.
    In the final Transport Rule, EPA explained its intent to capture 
``reductions that occur due to state rules, consent decrees, and other 
planned changes in generation patterns that occur after 2012, but 
during or prior to 2014'' in the 2014 state budgets (76 FR 48261). 
Commenters on the revisions rule noted that EPA inadvertently included 
pollution control installation requirements from a Georgia state rule 
whose deadlines at certain units actually extend beyond 2014. To 
correct the alignment of the Georgia 2014 state budgets with the 
requirements for affected units in Georgia to install controls by the 
state rule's deadlines, EPA is increasing Georgia's 2014 state budgets 
by 40,334 tons of SO2, 13,198 tons of annual NOX, 
and 5,762 tons of ozone-season NOX.
    (3) Revise the Indiana SO2 budgets for 2012 and 2014.
    EPA is revising the Indiana 2012 and 2014 annual SO2 
budgets based on comments received on the proposed revisions rule (76 
FR 63860, October 14, 2011) regarding post-combustion control status at 
Gallagher Units 2 and 4. Commenters identified an erroneous assumption 
of flue gas desulphurization (FGD, or scrubber) with 86 percent removal 
at units that have actually installed dry sorbent injection (DSI) 
technology with a 60 percent removal rate and an emission rate limit of 
0.8 lbs/mmBtu established in a NSR settlement agreement. EPA has 
recalculated the projected emissions at these units, and that 
recalculation supports a 3,465 ton increase in the state's annual 
SO2 budget.
    Commenters on the revisions rule also identified a facility in 
Indiana, Gibson Unit 5, which currently faces immediate-term 
limitations regarding the amount of flue gas that can be treated in its 
existing FGD. In the final Transport Rule analysis, EPA relied on the 
SO2 removal efficiency that this facility reported at its 
scrubber to the Energy Information Administration (EIA). However, EPA 
has since determined that this reported value only intended to address 
the removal efficiency for the portion of the flue gas treated in the 
scrubber. EPA has recalculated the projected emissions for this unit 
using the most recent data reported by this facility to EIA on form

[[Page 10344]]

860 for 2009, which includes the scrubber's removal efficiency and the 
portion of flue gas treated. This recalculation supports an increase to 
Indiana's 2012 and 2014 SO2 budget of an additional 1,873 
tons (5,338 tons total).
    (4) Revise the Kansas SO2 and annual NOX 
budgets for 2012 and 2014.
    Commenters on the revisions rule provided information showing that 
one unit at the Quindaro plant in Kansas is in an out-of-merit-order 
dispatch area with conditions likely to necessitate what would 
otherwise be non-economic generation. EPA re-calculated the emissions 
from this plant with non-economic generation to account for the input 
assumption changes. These calculations yield increases to the Kansas 
2012 and 2014 state budgets for annual SO2 of 452 tons and 
annual NOX of 640 tons.
    In the final Transport Rule, EPA explained its intent to capture 
``reductions that occur due to state rules, consent decrees, and other 
planned changes in generation patterns that occur after 2012, but 
during or prior to 2014'' in the 2014 state budgets (76 FR 48261). 
Commenters on the revisions rule noted that EPA inadvertently included 
an emission rate requirement from a consent decree affecting a Kansas 
facility whose deadline actually extends beyond 2014. To correct the 
alignment of the Kansas 2014 state budget with the requirements for 
affected units in Kansas to meet the emission rate limitation by the 
consent decree's deadlines, EPA is increasing the Kansas 2014 annual 
NOX budget by an additional 5,154 tons (5,794 tons total).
    (5) Revise the Louisiana ozone season NOX budgets for 
2012 and 2014 and adjust the ozone season new unit set-aside.
    EPA is increasing the Louisiana 2012 and 2014 ozone-season 
NOX budgets based on comments received on the revisions rule 
demonstrating that the Stall and Lieberman plants are in an out-of-
merit-order dispatch area with conditions likely to necessitate what 
would otherwise be non-economic generation. EPA re-calculated the 
emissions from the Stall and Lieberman plants with non-economic 
generation to account for the input assumption changes. These 
calculations yield increases to Louisiana's 2012 and 2014 state budgets 
for ozone-season NOX of 89 tons.
    Comments on the revisions rule also noted that in calculating the 
Louisiana ozone-season NOX new unit set-aside, EPA included 
projected emissions from a planned new facility, Washington Parish, 
which will not in fact come into service in Louisiana. EPA is therefore 
reducing the size of Louisiana's ozone-season NOX new unit 
set-aside in 2012 and 2014 to 2 percent (from the previous 3 percent) 
to account for the exclusion of these projected emissions from the 
relevant calculation. This revision means that fewer allowances will 
need to be held in reserve for the new unit set-aside; after this 
revision's effective date, EPA will reallocate any allowances in excess 
of the revised new unit set-aside to existing units in the state by the 
same existing unit allowance allocation methodology as previously 
finalized.
    (6) Revise the Mississippi ozone season NOX budgets for 
2012 and 2014.
    EPA is increasing the Mississippi 2012 and 2014 ozone-season 
NOX budgets based on comments received on the revisions rule 
demonstrating that the Moselle plant is in an out-of-merit-order 
dispatch area with conditions likely to necessitate what would 
otherwise be non-economic generation.
    EPA re-calculated the emissions from the Moselle plant with non-
economic generation to account for the input assumption changes. These 
calculations yield increases to Mississippi's 2012 and 2014 state 
budgets for ozone-season NOX of 115 tons.
    (7) Revise the Missouri annual and ozone season NOX 
budgets for 2012 and 2014 and correct the SO2, annual 
NOX, and ozone season NOX new unit set-aside 
budgets for an omitted operating new facility.
    EPA is increasing the Missouri 2012 and 2014 annual and ozone-
season NOX budgets to account for operational constraints at 
six plants based upon comments received on the revisions rule. The 
commenters provided information showing that these units were in out-
of-merit-order dispatch areas with conditions likely to necessitate 
what would otherwise be non-economic generation.
    EPA re-calculated the emissions from these six plants with non-
economic generation to account for the input assumption changes. These 
calculations yield increases to Missouri's 2012 and 2014 state budgets 
for annual NOX of 26 tons and ozone-season NOX of 
26 tons.
    Comments on the revisions rule identified Iatan Unit 2 as 
commencing commercial operation on or after January 1, 2010, qualifying 
it as a new unit under the final Transport Rule's unit-level allocation 
methodology (76 FR 48290); however, the final Transport Rule 
erroneously omitted this unit's projected emissions from the 
calculation of Missouri's new unit set-asides. EPA is therefore 
revising the portion of Missouri's SO2, annual 
NOX, and ozone-season NOX budgets dedicated to 
the state's new unit set-asides so that they take into account this 
unit's projected emissions, consistent with the new unit set-aside 
methodology in the final Transport Rule. EPA is only applying this 
revision for 2013 and beyond, because the Agency has already recorded 
(i.e., distributed) allowances under the Missouri state budget for the 
2012 control period. Iatan Unit 2 remains eligible to request allowance 
allocation from the new unit set-asides for any control period under 
the program. This revision yields an ozone-season NOX new 
unit set-aside of 6 percent, an annual NOX new unit set-
aside of 6 percent, and an SO2 new unit set-aside of 3 
percent for 2013 and beyond for Missouri. This revision to Missouri's 
new unit set-aside necessitates changes to allowance allocations to 
existing units in 2013 and beyond.
    (8) Revise the Ohio SO2, annual NOX, and 
ozone season NOX budgets for 2012 and 2014.
    EPA is increasing Ohio's 2012 and 2014 annual SO2, 
annual NOX, and ozone-season NOX budgets to 
account for operational constraints at two plants, Conesville and 
Muskingum River, based on comments received on the revisions rule. The 
commenter provided information showing that these plants were in out-
of-merit-order dispatch areas with conditions likely to necessitate 
what would otherwise be non-economic generation.
    EPA re-calculated the emissions from these two plants with non-
economic generation to reflect the input assumption changes. These 
calculations yield increases to Ohio's 2012 and 2014 state budgets for 
annual SO2 of 5,163 tons, annual NOX of 547 tons, 
and ozone-season NOX of 257 tons.
    EPA is finalizing additional adjustments to Ohio's 2012 and 2014 
annual and ozone-season NOX budgets to correct an erroneous 
assumption of an SCR at Bayshore 4. There is no SCR planned or under 
construction at this facility. This results in an additional 2,218 ton 
increase (2,765 ton total) in the state's annual NOX budget 
and a 964 ton increase (1,221 ton total) for the ozone-season 
NOX budget.
    (9) Revise the Nebraska SO2 budgets for 2012 and 2014.
    EPA is finalizing revisions to the Nebraska 2012 and 2014 
SO2 budgets, based on comments on the revisions rule, to 
correct assumptions regarding FGD pollution control technology at 
Whelan Energy Center Units 1 and 2 and Nebraska City Unit 2. The 
commenter noted that the technology at Nebraska Unit 2 and Whelan Unit 
2 is

[[Page 10345]]

dry FGD technology, whereas EPA had assumed wet FGD technology with a 
higher SO2 removal efficiency than the actual dry FGD 
technology that those units achieve. Additionally, EPA is also revising 
its assumption of FGD technology at Whelan Energy Center Unit 1. There 
is no FGD present, planned, or under construction at the unit. These 
adjustments result in an increase of 3,110 tons to the 2012 and 2014 
annual SO2 budgets for the state.
    (10) Revise the New York SO2, annual NOX, and 
ozone season NOX budgets for 2012 and 2014.
    EPA is increasing New York's 2012 and 2014 annual SO2, 
annual NOX, and ozone-season NOX budgets based on 
comments received on the revisions rule demonstrating that the East 
River plant is in an out-of-merit-order dispatch area with conditions 
likely to necessitate what would otherwise be non-economic generation. 
EPA re-calculated the emissions from this facility with out-of-merit-
order dispatch to reflect the input assumption changes. These 
calculations yield increases to New York's 2012 and 2014 state budgets 
for annual SO2 of 84 tons, annual NOX of 694 
tons, and ozone-season NOX of 127 tons.
    EPA is also finalizing an adjustment of 5,360 tons to New York's 
2012 and 2014 SO2 budgets based on comments received on the 
revisions rule. Commenters identified two facilities, Dunkirk and 
Huntley, with existing dry sorbent injection (DSI) technology for which 
EPA had assumed an SO2 removal rate of 70 percent but which 
actually achieves a removal rate of only 53 percent. EPA recalculated 
the projected emissions for these units based on this revised 
assumption and is increasing the New York 2012 and 2014 SO2 
budgets accordingly.
    (11) Revise the Oklahoma ozone-season NOX budgets for 
2013 and 2014.
    EPA is increasing the Oklahoma 2013 \3\ and 2014 ozone-season 
NOX budget based upon comments received on the revisions 
rule demonstrating that the Comanche plant is in an out-of-merit-order 
dispatch area with conditions likely to necessitate what would 
otherwise be non-economic generation.
---------------------------------------------------------------------------

    \3\ These changes do not apply to the Oklahoma 2012 budget 
because similar changes were already made to the affected units' 
operation in 2012, as described in the Technical Support Document 
``Determination of State Budgets for the Final Ozone Supplemental of 
the Transport Rule'' (EPA-HQ-OAR-2009-0491-485, pg. 5-7).
---------------------------------------------------------------------------

    EPA re-calculated the emissions from the Comanche plant with non-
economic generation to account for the input assumption changes. These 
calculations yield increases to the Oklahoma 2013 and 2014 state 
budgets for ozone-season NOX of 859 tons.
    (12) Revise the South Carolina SO2 budgets for 2012 and 
2014.
    EPA is finalizing an 8,013 ton increase to South Carolina's 2012 
and 2014 annual SO2 budgets based on comments received on 
the revision rule regarding post-combustion control technology at three 
units. This action revises the assumption of an FGD at the W S Lee 
Facility. There are no FGDs planned, under construction, or expected to 
be online in 2012 or 2014 at this facility.
    (13) Revise the Texas annual NOX and ozone season 
NOX budgets for 2012 and 2014.
    EPA is increasing the Texas 2012 and 2014 annual and ozone-season 
NOX budgets to account for operational constraints at six 
plants based on comments received on the revisions rule: Jones, Moore 
County, Nichols, Plant X, Knox Lee, and Wilkes. The commenters provided 
information showing that these plants were in out-of-merit-order 
dispatch areas with conditions likely to necessitate what would 
otherwise be non-economic generation.
    EPA re-calculated the emissions from these plants with non-economic 
generation to account for the input assumption changes. These 
calculations yield increases to the Texas 2012 and 2014 state budgets 
for annual NOX of 2,731 tons, and ozone-season 
NOX of 1,142 tons.

II. Statutory and Executive Order Reviews

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

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is a ``significant regulatory action.'' Accordingly, EPA 
submitted this action to the Office of Management and Budget (OMB) for 
review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 
2011) and any changes made in response to OMB recommendations have been 
documented in the docket for this action.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden. 
This action makes relatively minor revisions to the emission budgets 
and allowance allocations or allowance allocations only in certain 
states in the final Transport Rule and corrects minor technical errors 
which are ministerial. However, the Office of Management and Budget 
(OMB) has previously approved the information collection requirements 
contained in the final Transport Rule under the provisions of the 
Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB 
control number 2060-0667. The OMB control numbers for EPA's regulations 
in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to prepare a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements under the Administrative 
Procedure Act or any other statute unless the agency certifies that the 
rule will not have a significant economic impact on a substantial 
number of small entities. Small entities include small businesses, 
small organizations, and small governmental jurisdictions.
    For purposes of assessing the impacts of this rule on small 
entities, small entity is defined as: (1) A small business as defined 
by the Small Business Administration's (SBA) regulations at 13 CFR 
121.201; (2) a small governmental jurisdiction that is a government of 
a city, county, town, school district or special district with a 
population of less than 50,000; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    After considering the economic impacts of this action on small 
entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities. The small 
entities directly regulated by this action are electric power 
generators whose ultimate parent entity has a total electric output of 
4 million megawatt-hours (MWh) or less in the previous fiscal year. We 
have determined that the changes considered in this proposed rulemaking 
pose no additional burden for small entities. The proposed revision to 
the new unit set-asides in Arkansas, Missouri, and Texas would yield an 
extremely small change in unit-level allowance allocations to existing 
units, including small entities, such that it would not affect the 
analysis conducted on small entity impacts under the finalized 
Transport Rule. In all other states, the revisions proposed in this 
rulemaking would yield additional allowance allocations to all units, 
including small entities, without increasing program stringency, such 
that it is not possible for the impact to small entities to be any 
larger than that already considered and reviewed in the finalized 
Transport Rule.

D. Unfunded Mandates Reform Act

    This rule does not contain a Federal mandate that may result in 
expenditures of $100 million or more for State, local, and tribal 
governments, in the aggregate, or the private sector in any one year. 
This action is increasing the budgets and increasing the total number 
of allowances or maintaining the same budget but revising unit-level 
allocations in several other states in the Transport Rule. Thus, this 
rule is not subject to the requirements of sections 202 or 205 of UMRA.
    In developing the final Transport Rule, EPA consulted with small 
governments pursuant to a plan established under section 203 of UMRA to 
address impacts of regulatory requirements in the rule that might 
significantly or uniquely affect small governments.

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, as 
specified in Executive Order 13132. This action makes relatively minor 
revisions to the emissions budgets and allowance allocations or 
allowance allocations only in certain states in the final Transport 
Rule. Thus, Executive Order 13132 does not apply to this rule. EPA did 
provide information to state and local officials during development of 
both the proposed and final Transport Rule.

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

    This action does not have tribal implications, as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000). This action 
makes relatively minor revisions to the emissions budgets and allowance 
allocations in several states in the final Transport Rule and helps 
ease the transition from CAIR. Indian country new unit set-asides will 
increase slightly or remain unchanged in the states affected by this 
action. Thus, Executive Order 13175 does not apply to this action. EPA 
consulted with tribal officials during the process of promulgating the 
final Transport Rule to permit them to have meaningful and timely input 
into its development.

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

    This action is not subject to EO 13045 (62 FR 19885, April 23, 
1997) because it is not economically significant as defined in EO 
12866, and because the Agency does not believe the environmental health 
or safety risks addressed by this action present a disproportionate 
risk to children. Analyses by EPA that show how the emission reductions 
from the strategies in the final Transport Rule will further improve 
air quality and children's health can be found in the final Transport 
Rule RIA.

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

    This action is not a ``significant energy action'' as defined in 
Executive Order 13211 (66 FR 28355 (May 22, 2001)), because it is not 
likely to have a significant adverse effect on the supply, 
distribution, or use of energy. EPA believes that there is no 
meaningful impact to the energy supply beyond that which is reported 
for the Transport Rule program in the final Transport Rule.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note) 
directs EPA to use voluntary consensus standards in its regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. NTTAA directs EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable voluntary consensus standards.
    As described in section XII.I of the preamble to the final 
Transport Rule, the Transport Rule program requires all sources to meet 
the applicable monitoring requirements of 40 CFR part 75. Part 75 
already incorporates a number of voluntary consensus standards. This 
action does not involve technical standards. Therefore, EPA did not 
consider the use of any voluntary consensus standards.

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

    Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes 
federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    In the Final Revisions Rule Significant Contribution Assessment 
Technical Support Document in the docket to this rulemaking, EPA 
assessed impacts of the emission changes in this rule on air quality 
throughout the Transport Rule region. For SO2, the estimated 
air quality impacts were minimal and no additional nonattainment or 
maintenance areas were identified. EPA also assessed the relationship 
between the NOX emission inventories in each affected state 
and the finalized revisions to annual and ozone-season NOX 
budgets and found the revisions represent small percentages of each 
state's total emissions in 2014. As a result, EPA does not believe 
these technical revisions would affect any of the conclusions supported 
by the air quality and environmental justice analyses conducted for the 
final Transport Rule.
    Based on the significant contribution assessment in the technical 
support document for this action, EPA has determined that this action 
will not have disproportionately high and adverse human health or 
environmental effects on minority or low-income populations because it 
does not affect the level of protection provided to human health or the 
environment. EPA believes that the vast majority of communities and 
individuals in areas covered by the Transport Rule program inclusive of 
this action, including numerous low-income, minority, and tribal 
individuals and communities in both rural areas and inner cities in the 
eastern and central U.S., will see significant improvements in air 
quality and resulting improvements in health. EPA's assessment of the 
effects of the final Transport Rule program on these communities is 
available in section XII.J of the preamble to the final Transport Rule.

K. Congressional Review Act

    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 rule and other 
required information to the U.S. Senate, the U.S. House of 
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 action is a ``major rule'' as defined by 5 U.S.C. 
804(2). This rule will be effective April 23, 2012.

L. Judicial Review

    Petitions for judicial review of this action must be filed in the 
United States Court of Appeals for the District of Columbia Circuit by 
April 23, 2012. Section 307(b)(1) of the CAA indicates which Federal 
Courts of Appeal have venue for petitions of review of final actions by 
EPA. This section provides, in part, that petitions for review must be 
filed in the Court of Appeals for the District of Columbia Circuit if 
(i) the agency action consists of ``nationally applicable regulations 
promulgated, or final action taken, by the Administrator,'' or (ii) 
such action is locally or regionally applicable, if ``such action is 
based on a determination of nationwide scope or effect and if in taking 
such action the Administrator finds and publishes that such action is 
based on such a determination.''
    In the final Transport Rule, EPA determined that ``[a]ny final 
action related to the Transport Rule is `nationally applicable' within 
the meaning of section 307(b)(1).'' 76 FR 48,352. Through this rule, 
EPA is revising specific aspects of the final Transport Rule. This rule 
therefore is a final action related to the Transport Rule and as such 
is covered by the determination of national applicability made in the 
final Transport Rule. Thus, pursuant to section 307(b) any petitions 
for review of this action must be filed in the Court of Appeals for the 
District of Columbia Circuit within 60 days from the date final action 
is published in the Federal Register. Filing a petition for 
reconsideration of this action does not affect the finality of this 
rule 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. In addition, 
pursuant to CAA section 307(b)(2) this action may not be challenged 
later in proceedings to enforce its requirements.
