Approval and Promulgation of Air Quality Implementation Plan;
Kansas; Proposed Disapproval of Interstate Transport State
Implementation Plan Revision for the 2006 24-Hour PM2.5 NAAQS
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: Pursuant to our authority under the Clean Air Act (CAA or
Act), EPA is proposing to disapprove the portion of the Kansas CAA
``Infrastructure'' State Implementation Plan (SIP) submittal addressing
significant contribution to nonattainment or interference with
maintenance in another State with respect to the 2006 24-hour fine
particle (PM2.5) National Ambient Air Quality Standards
NAAQS). On April 12, 2010, Kansas submitted a State Implementation Plan
(SIP) intended to address the infrastructure SIP requirements for
``infrastructure.'' The submittal also included language to address the
interstate transport requirements under the CAA. In this action, EPA is
proposing to disapprove the portion of the Kansas SIP revision intended
to address requirements prohibiting a State's emissions from
significantly contributing to nonattainment or interfering with
maintenance of the NAAQS in any other State. The rationale for the
proposed action is described in this proposal.

II. What is the background for this action?
On December 18, 2006, EPA revised the 24-hour average
PM2.5 primary and secondary NAAQS from 65 micrograms per
cubic meter ([mu]g/m\3\) to 35 [mu]g/m\3\. Section 110(a)(1) of the CAA
requires States to submit infrastructure SIPs to address a new or
revised NAAQS within 3 years after promulgation of such standards, or
within such shorter period as EPA may prescribe.\1\ As provided by
Section 110(k)(2), within 12 months of a determination that a submitted
SIP is complete under 110(k)(1), the Administrator shall act on the
plan. As authorized in Section 110(k)(3) of the Act, where portions of
the State submittals are severable, within that 12 month period EPA may
decide to approve only those severable portions of the submittals that
meet the requirements of the Act. When the deficient provisions are not
severable from the other submitted provisions, EPA must propose
disapproval of the submittals, consistent with Section 110(k)(3) of the
Act.
---------------------------------------------------------------------------
\1\ The rule for the revised PM2.5 NAAQS was signed
by the Administrator and publically disseminated on September 21,
2006. Because EPA did not prescribe a shorter period for 110(a) SIP
submittals, these submittals for the 2006 24-hour NAAQS were due on
September 21, 2009, three years from the September 21, 2006
signature date.
---------------------------------------------------------------------------
Section 110(a)(2) lists the elements that such new infrastructure
SIPs must address, as applicable, including Section 110(a)(2)(D)(i),
which pertains to interstate transport of certain emissions. On
September 25, 2009, EPA issued its ``Guidance on SIP Elements Required
Under Sections 110(a)(1) and (2) for the 2006 24-Hour Fine Particle
(PM2.5) National Ambient Air Quality Standards (NAAQS)''
(2009 Guidance). EPA developed the 2009 Guidance to make
recommendations to States for making submissions to meet the
requirements of Section 110, including 110(a)(2)(D)(i) for the revised
2006 24-hour PM2.5 NAAQS.
As identified in the 2009 Guidance, the ``good neighbor''
provisions in Section 110(a)(2)(D)(i) require each State to submit a
SIP that prohibits emissions that adversely affect another State in the
ways contemplated in the statute. Section 110(a)(2)(D)(i) contains four
distinct requirements related to the impacts of interstate transport.
The SIP must prevent sources in the State from emitting pollutants in
amounts which will: (1) Contribute significantly to nonattainment of
the NAAQS in other States; (2) interfere with maintenance of the NAAQS
in other States; (3) interfere with provisions to prevent significant
deterioration of air quality in other States; or (4) interfere with
efforts to protect visibility in other States.
In the 2009 Guidance, EPA indicated that SIP submissions from
States pertaining to the ``significant contribution'' and ``interfere
with maintenance'' requirements of Section 110(a)(2)(D)(i)(I) should
contain adequate provisions to prohibit air pollutant emissions from
within the State that contribute significantly to nonattainment or
interfere with maintenance of the NAAQS in any other State. EPA further
indicated that the State's submission should explain whether or not
emissions from the State
[[Page 14833]]
have this impact and, if so, address the impact. EPA stated that the
State's conclusion should be supported by an adequate technical
analysis. EPA recommended the various types of information that could
be relevant to support the State SIP submission, such as information
concerning emissions in the State, meteorological conditions in the
State and the potentially impacted States, monitored ambient
concentrations in the State, and air quality modeling. Furthermore, EPA
indicated that States should address the ``interfere with maintenance''
requirement independently which requires an evaluation of impacts on
areas of other States that are meeting the 2006 24-hour
PM2.5 NAAQS, not merely areas designated nonattainment.
Lastly in the 2009 Guidance, EPA stated that States could not rely on
the Clean Air Interstate Rule (CAIR) to comply with CAA Section
110(a)(2)(D)(i) requirements for the 2006 24-hour PM2.5
NAAQS because CAIR does not address this NAAQS.
EPA promulgated the CAIR on May 12, 2005 (see 70 FR 25162). CAIR
required States to reduce emissions of sulfur dioxide and nitrogen
oxides that significantly contribute to, and interfere with maintenance
of the 1997 NAAQS for PM2.5 and/or ozone in any downwind
State. CAIR was intended to provide States covered by the rule with a
mechanism to satisfy their CAA Section 110(a)(2)(D)(i)(I) obligations
to address significant contribution to downwind nonattainment and
interference with maintenance in another State with respect to the 1997
ozone and PM2.5 NAAQS. Many States adopted the CAIR
provisions and submitted SIPs to EPA to demonstrate compliance with the
CAIR requirements in satisfaction of their 110(a)(2)(D)(i)(I)
obligations for those two pollutants.
EPA was sued by a number of parties on various aspects of CAIR, and
on July 11, 2008, the U.S. Court of Appeals for the District of
Columbia Circuit issued its decision to vacate and remand both CAIR and
the associated CAIR Federal Implementation Plans (FIP) in their
entirety. North Carolina v. EPA, 531 F.3d 836 (DC Cir. Jul. 11, 2008).
However, in response to EPA's petition for rehearing, the Court issued
an order remanding CAIR to EPA without vacating either CAIR or the CAIR
FIPs. North Carolina v. EPA, 550 F.3d 1176 (DC Cir. Dec. 23, 2008). The
Court thereby left CAIR in place in order to ``temporarily preserve the
environmental values covered by CAIR'' until EPA replaces it with a
rule consistent with the Court's opinion. Id. at 1178. The Court
directed EPA to ``remedy CAIR's flaws'' consistent with its July 11,
2008, opinion, but declined to impose a schedule on EPA for completing
that action. Id.
In order to address the judicial remand of CAIR, EPA has proposed a
new rule to address interstate transport pursuant to Section
110(a)(2)(D)(i)(I), the ``Federal Implementation Plans To Reduce
Interstate Transport of Fine Particulate Matter and Ozone'' (Transport
Rule).\2\ As part of the proposed Transport Rule, EPA specifically
examined the Section 110(a)(2)(D)(i)(I) requirement that emissions from
sources in a State must not ``significantly contribute to
nonattainment'' and ``interfere with maintenance'' of the 2006 24-hour
PM2.5 NAAQS by other States. The modeling performed for the
proposed Transport Rule shows that Kansas significantly contributes to
nonattainment and interferes with maintenance of the 2006 24-hour
PM2.5 NAAQS in downwind areas.\3\
---------------------------------------------------------------------------
\2\ See ``Federal Implementation Plans to Reduce Interstate
Transport of Fine Particulate Matter and Ozone; Proposed Rule,'' 75
FR 45210 (August 2, 2010).
\3\ See Section IV on Defining ``Significant Contribution'' and
``Interference With Maintenance,'' 75 FR 45229 of ``Federal
Implementation Plans to Reduce Interstate Transport of Fine
Particulate Matter and Ozone; Proposed Rule,'' 75 FR 45210 (August
2, 2010).
---------------------------------------------------------------------------
On April 12, 2010, EPA received a SIP revision from the State of
Kansas intended to address the requirements of Section
110(a)(2)(D)(i)(I) for the 2006 24-hour PM2.5 NAAQS as well
as other requirements of Section 110(a)(2). In this rulemaking, EPA is
addressing only the requirements that pertain to prohibiting sources in
Kansas from emitting pollutants that will significantly contribute to
nonattainment or interfere with maintenance of the 2006 24-hour
PM2.5 NAAQS in other States. In its submission, the State of
Kansas indicated that emissions from the State do not significantly
interfere with the attainment nor maintenance of the 2006 24-hour
PM2.5 NAAQS in downwind States. The submission included a
description of relevant State actions intended to address the
interstate transport of emissions.
III. What is EPA's evaluation of the State's submittal?
On April 12, 2010, EPA received an Infrastructure SIP revision from
the State of Kansas intended to address the requirements of Section
110(a)(2)(D)(i)(I) with respect to the 2006 PM2.5 NAAQS. The
portion of Kansas' submittal to address the Section 110(a)(2)(D)(i)(I)
obligations indicates that the State has implemented several actions to
address interstate transport with respect to the 2006 24-hour
PM2.5 NAAQS.
Kansas' submittal describes how the State believes it meets
transport requirements based in part on recent controls established for
SO2 and NOX emissions from EGUs in the State.
Kansas summarizes that the reductions represent a 32% reduction in the
total Kansas point source NOX emissions and a 58% reduction
in the total Kansas point source SOX emissions from the 2005
National Emissions Inventory (NEI). However, EPA's preliminary
photochemical modeling for the proposed Transport Rule, to address
110(a)(2)(D)(i)(I), indicates that emissions from the State of Kansas
significantly contribute to nonattainment and interfere with
maintenance in other States with respect to the 2006 24-Hour
PM2.5 NAAQS.\4\
---------------------------------------------------------------------------
\4\ See Section IV on Defining ``Significant Contribution'' and
``Interference With Maintenance,'' 75 FR 45229 of ``Federal
Implementation Plans to Reduce Interstate Transport of Fine
Particulate Matter and Ozone; Proposed Rule,'' 75 FR 45210 (August
2, 2010).
---------------------------------------------------------------------------
EPA's 2009 Guidance stated that a State's SIP submission pertaining
to the requirement of Section 110(a)(2)(D)(i)(I) must be supported by
an adequate technical analysis.\5\ EPA recommended the various types of
information that could be relevant to support the State's SIP
submission. While Kansas submitted a description of actions that have
been implemented to reduce NOX and SO2 emissions,
the State did not further evaluate or demonstrate with a technical
analysis that these measures address the requirements of
110(a)(2)(D)(i)(I) to prohibit Kansas' air pollutant emissions from
significantly contributing to nonattainment or interfering with
maintenance in other States. EPA believes that the documentation
submitted does not address the requirements of 110(a)(2)(D)(i)(I), in
part, because the submittal lacks a technical demonstration.
---------------------------------------------------------------------------
\5\ See William T. Harnett, Director, Air Quality Policy
Division, Office of Air Quality Planning and Standards. ``Guidance
on SIP Elements Required Under Sections 110(a)(1) and (2) for the
2006 24-hour Fine Particle (PM2.5) National Ambient Air
Quality Standards.'' Memorandum to EPA Air Division Directors,
Regions I-X (September 25, 2009).
---------------------------------------------------------------------------
Based upon our evaluation, EPA is proposing that this SIP revision
does not meet the requirements of 110(a)(2)(D)(i)(I) of the CAA.
Therefore, EPA is proposing disapproval of the portion of Kansas'
Infrastructure SIP relating to Interstate Transport, Section
110(a)(2)(D)(i)(I). The submitted
[[Page 14834]]
provisions are severable from each other. Therefore, EPA is proposing
to disapprove those provisions which relate to the Section
110(a)(2)(D)(i)(I) demonstration and will act on the remainder of the
SIP submission in a subsequent rulemaking.
Also, under Section 179(a) of the CAA, final disapproval of a
submittal that addresses a requirement of a Part D Plan (42 U.S.C.A.
Sec. Sec. 7501-7515), or is required in response to a finding of
substantial inadequacy as described in section 7410(k)(5) (SIP call),
starts a sanctions clock. The provisions in the submittal we are
proposing to disapprove were not submitted to meet either of those
requirements. Therefore, if EPA takes final action to disapprove this
submittal, no sanctions will be triggered.
The full or partial disapproval of a State implementation plan
revision triggers the requirement under Section 110(c) that EPA
promulgate a FIP no later than 2 years from the date of the disapproval
unless the State corrects the deficiency, and the Administrator
approves the plan or plan revision before the Administrator promulgates
such FIP. The Transport Rule FIP, if finalized in the manner proposed,
may address these requirements for the State of Kansas.
IV. What action is EPA proposing?
We are proposing to disapprove a submission from the State of
Kansas intended to demonstrate that Kansas has adequately addressed the
elements of CAA Section 110(a)(2)(D)(i)(I) that require the State's SIP
to contain adequate provisions to prohibit air pollutant emissions from
sources within a State from significantly contributing to nonattainment
in or interference with maintenance of the 2006 24-hour
PM2.5 NAAQS in any other State. We are proposing to
determine that the Kansas submission does not contain adequate
provisions to prohibit air pollutant emissions from within the State
that significantly contribute to nonattainment in or interference with
maintenance of the 2006 24-hour PM2.5 NAAQS in other
downwind States. Any remaining elements of the submittal, including
language to address other CAA Section 110(a)(2) elements, including
Section 110(a)(2)(D)(i)(II) regarding interference with measures
required in the applicable SIP for another State designed to prevent
significant deterioration of air quality and protect visibility, are
not addressed in this action. EPA is proposing to disapprove only the
provisions which relate to the Section 110(a)(2)(D)(i)(I)
demonstration.
V. Statutory and Executive Order Reviews
Under the 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 act on State law as meeting
Federal requirements and does not impose additional requirements beyond
those imposed by State law.
Executive Order 12866, Regulatory Planning and Review
This action is not a ``significant regulatory action'' under the
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is
therefore not subject to review under the Executive Order.
Paperwork Reduction Act
This action does not impose an information collection burden under
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq,
because this proposed SIP disapproval under Section 110 and subchapter
I, part D of the Clean Air Act will not in-and-of itself create any new
information collection burdens but simply disapproves certain State
requirements for inclusion into the SIP. Burden is defined at 5 CFR
1320.3(b).
Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to conduct a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements 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 not-for-profit enterprises, and small governmental
jurisdictions. For purposes of assessing the impacts of today's 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 today's proposed rule on
small entities, I certify that this action will not have a significant
impact on a substantial number of small entities. This rule does not
impose any requirements or create impacts on small entities. This
proposed SIP disapproval under Section 110 and subchapter I, part D of
the Clean Air Act will not in-and-of itself create any new requirements
but simply disapproves certain State requirements for inclusion into
the SIP. Accordingly, it affords no opportunity for EPA to fashion for
small entities less burdensome compliance or reporting requirements or
timetables or exemptions from all or part of the rule. The fact that
the Clean Air Act prescribes that various consequences (e.g., higher
offset requirements) may or will flow from this disapproval does not
mean that EPA either can or must conduct a regulatory flexibility
analysis for this action. Therefore, this action will not have a
significant economic impact on a substantial number of small entities.
We continue to be interested in the potential impacts of this
proposed rule on small entities and welcome comments on issues related
to such impacts.
Unfunded Mandates Reform Act
This action contains no Federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531-1538 for State, local, or Tribal governments or the private
sector.'' EPA has determined that the proposed disapproval action does
not include a Federal mandate that may result in estimated costs of
$100 million or more to either State, local, or Tribal governments in
the aggregate, or to the private sector. This action proposes to
disapprove pre-existing requirements under State or local law, and
imposes no new requirements. Accordingly, no additional costs to State,
local, or Tribal governments, or to the private sector, result from
this action.
Executive Order 13132, Federalism
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that 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.''
This action does not have federalism implications. It will not have
substantial direct effects on the States, on the relationship between
the national
[[Page 14835]]
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 merely disapproves certain State
requirements for inclusion into the SIP and does not alter the
relationship or the distribution of power and responsibilities
established in the Clean Air Act. However, today's proposed disapproval
does not have federalism implications. Thus, Executive Order 13132 does
not apply to this action.
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), because the SIP
EPA is proposing to disapprove would not apply in Indian country
located in the State, and EPA notes that it will not impose substantial
direct costs on Tribal governments or preempt Tribal law. Thus,
Executive Order 13175 does not apply to this action.
Executive Order 13045, Protection of Children From Environmental Health
Risks and Safety Risks
EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997)
as applying only to those regulatory actions that concern health or
safety risks, such that the analysis required under Section 5-501 of
the Executive Order has the potential to influence the regulation. This
action is not subject to Executive Order 13045 because it because it is
not an economically significant regulatory action based on health or
safety risks subject to Executive Order 13045 (62 FR 19885, April 23,
1997).This proposed SIP disapproval under Section 110 and subchapter I,
part D of the Clean Air Act will not in-and-of itself create any new
regulations but simply disapproves certain State requirements for
inclusion into the SIP.
Executive Order 13211, Actions That Significantly Affect Energy Supply,
Distribution or Use
This action is not subject to Executive Order 13211 (66 FR 28355,
May 22, 2001) because it is not a significant regulatory action under
Executive Order 12866.
National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, Section 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. The EPA
believes that this action is not subject to requirements of Section
12(d) of NTTAA because application of those requirements would be
inconsistent with the Clean Air Act.
Executive Order 12898: Federal Actions To Address Environmental Justice
in Minority Populations and Low-Income Populations
Executive Order 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.
EPA lacks the discretionary authority to address environmental
justice in this proposed action. In reviewing SIP submissions, EPA's
role is to approve or disapprove State choices, based on the criteria
of the Clean Air Act. Accordingly, this action merely proposes to
disapprove certain State requirements for inclusion into the SIP under
Section 110 and subchapter I, part D of the Clean Air Act and will not
in-and-of itself create any new requirements. Accordingly, it 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.
Statutory Authority
The statutory authority for this action is provided by Sections 110
of the CAA, as amended (42 U.S.C. 7410).
