Approval and Promulgation of Implementation Plans; South
Carolina; 110(a)(1) and (2) Infrastructure Requirements for the 1997
and 2006 Fine Particulate Matter National Ambient Air Quality Standards
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to approve the State Implementation Plans
(SIP), submitted by the State of South Carolina, through the Department
of Health and Environmental Control (DHEC), as demonstrating that the
State meets the requirements of sections 110(a)(1) and (2) of the Clean
Air Act (CAA or the Act) for the 1997 annual and 2006 24-hour fine
particulate matter (PM2.5) national ambient air quality
standards (NAAQS). Section 110(a) of the CAA requires that each state
adopt and submit a SIP for the implementation, maintenance, and
enforcement of each NAAQS promulgated by the EPA, which is commonly
referred to as an ``infrastructure'' SIP. South Carolina certified that
the South Carolina SIP contains provisions that ensure the 1997 annual
and 2006 24-hour PM2.5 NAAQS is implemented, enforced, and
maintained in South Carolina (hereafter referred to as ``infrastructure
submission''). South Carolina's infrastructure submissions, provided to
EPA on March 14, 2008, and on September 18, 2009, addressed all the
required infrastructure elements for the 1997 annual and 2006 24-hour
PM2.5 NAAQS with the exception of section 110(a)(2)(E)(ii)
and 110(a)(2)(G) which were submitted by South Carolina on April 3,
2012. South Carolina's April 3, 2012, submittal is being addressed in a
separate action.

I. Background
On July 18, 1997 (62 FR 36852), EPA established an annual
PM2.5 NAAQS at 15.0 micrograms per cubic meter ([mu]g/m\3\)
based on a 3-year average of annual mean PM2.5
concentrations. At that time, EPA also established a 24-hour NAAQS of
65 [mu]g/m\3\. See 40 CFR 50.7. On October 17, 2006 (71 FR 61144), EPA
retained the 1997 annual PM2.5 NAAQS at 15.0 [mu]g/m\3\
based on a 3-year average of annual mean PM2.5
concentrations, and promulgated a new 24-hour PM2.5 NAAQS of
35 [mu]g/m\3\ based on a 3-year average of the 98th percentile of 24-
hour concentrations. Pursuant to the CAA, SIPs meeting the requirements
of sections 110(a)(1) and (2) are to be submitted by states within
three years after promulgation of a new or revised NAAQS. Sections
110(a)(1) and (2) require states to address basic SIP requirements,
including emissions inventories, monitoring, and modeling to assure
attainment and maintenance of the NAAQS. States were required to submit
such SIPs to EPA no later than July 2000 for the 1997 annual
PM2.5 NAAQS, no later than October 2009 for the 2006 24-hour
PM2.5 NAAQS.
On March 4, 2004, Earthjustice submitted a notice of intent to sue
related to EPA's failure to issue findings of failure to submit related
to the ``infrastructure'' requirements for the 1997 annual
PM2.5 NAAQS. On March 10, 2005, EPA entered into a consent
decree with Earthjustice which required EPA, among other things, to
complete a Federal Register notice announcing EPA's determinations
pursuant to section 110(k)(1)(B) as to whether each state had made
complete submissions to meet the requirements of section 110(a)(2) for
the 1997 PM2.5 NAAQS by October 5, 2008. In accordance with
the consent decree, EPA made completeness findings for each state based
upon what the Agency received from each state for the 1997
PM2.5 NAAQS as of October 3, 2008.
On October 22, 2008, EPA published a final rulemaking entitled,
``Completeness Findings for Section 110(a) State Implementation Plans
Pertaining to the Fine Particulate Matter (PM2.5) NAAQS''
making a finding that each state had submitted or failed to submit a
complete SIP that provided the basic program elements of section
110(a)(2) necessary to implement the 1997 PM2.5 NAAQS (See
73 FR 62902). For those states that did receive findings, the findings
of failure to submit for all or a portion of a state's implementation
plan established a 24-month deadline for EPA to promulgate a Federal
Implementation Plan to address the outstanding SIP elements unless,
prior to that time, the affected states submitted, and EPA approved,
the required SIPs.
The findings that all or portions of a state's submission are
complete established a 12-month deadline for EPA to take action upon
the complete SIP elements in accordance with section 110(k). South
Carolina's infrastructure submissions were received by EPA on March 14,
2008, for the 1997 annual PM2.5 NAAQS and on September 18,
2009, for the 2006 24-hour PM2.5 NAAQS. The submissions were
determined to be complete on September 14, 2008, and March 18, 2010,
respectively. South Carolina was among other states that did not
receive findings of failure to submit because it had provided a
complete submission to EPA to address the infrastructure elements for
the 1997 PM2.5 NAAQS by October 3, 2008.
On July 6, 2011, WildEarth Guardians and Sierra Club filed an
amended complaint related to EPA's failure to take action on the SIP
submittal related to the ``infrastructure'' requirements for the 2006
24-hour PM2.5 NAAQS. On October 20, 2011, EPA entered into a
consent decree with WildEarth Guardians and Sierra Club which required
EPA, among other things, to complete a Federal Register notice of the
Agency's final action either approving, disapproving, or approving in
part and disapproving in part the South Carolina 2006 24-hour
PM2.5 NAAQS Infrastructure SIP submittal addressing the
applicable requirements of sections 110(a)(2)(A)-(H), (J)-(M), except
for section 110(a)(2)(C) the nonattainment area requirements and
section 110(a)(2)(D)(i) interstate transport requirements, by September
30, 2012.
Today's action is proposing to approve South Carolina's
infrastructure submission for the 1997 annual and 2006 24-hour
PM2.5 NAAQS for sections 110(a)(2)(A)-(H), (J)-(M), except
for sections 110(a)(2)(C)--the nonattainment area requirements;
110(a)(2)(D)(i)--the interstate transport requirements;
110(a)(2)(E)(ii)--board requirements; and 110(a)(2)(G)--emergency
powers. Requirements supporting EPA action on sections 110(a)(2)(E)(ii)
and 110(a)(2)(G) were submitted by South Carolina through a SIP
revision on April 3, 2012. South Carolina's April 3, 2012, SIP revision
is being addressed in a separate action. This action is not approving
any specific rule, but rather proposing that South Carolina's already
approved SIP meets certain CAA requirements.
II. What elements are required under sections 110(a)(1) and (2)?
Section 110(a) of the CAA requires states to submit SIPs to provide
for the implementation, maintenance, and enforcement of a new or
revised NAAQS within three years following the promulgation of such
NAAQS, or within such shorter period as EPA may prescribe. Section
110(a) imposes the obligation upon states to make a SIP submission to
EPA for a new or revised NAAQS, but the contents of that submission may
vary depending upon the facts and circumstances. In particular, the
data and analytical tools
[[Page 33374]]
available at the time the state develops and submits the SIP for a new
or revised NAAQS affects the content of the submission. The contents of
such SIP submissions may also vary depending upon what provisions the
state's existing SIP already contains. In the case of the 1997 annual
and 2006 24-hour PM2.5 NAAQS, some states may need to adopt
language specific to the PM2.5 NAAQS to ensure that they
have adequate SIP provisions to implement the PM2.5 NAAQS.
More specifically, section 110(a)(1) provides the procedural and
timing requirements for SIPs. Section 110(a)(2) lists specific elements
that states must meet for ``infrastructure'' SIP requirements related
to a newly established or revised NAAQS. As mentioned above, these
requirements include SIP infrastructure elements such as modeling,
monitoring, and emissions inventories that are designed to assure
attainment and maintenance of the NAAQS. The requirements that are the
subject of this proposed rulemaking are listed below \1\ and in EPA's
October 2, 2007, memorandum entitled ``Guidance on SIP Elements
Required Under Section 110(a)(1) and (2) for the 1997 8-Hour Ozone and
PM2.5 National Ambient Air Quality Standards.'' and
September 25, 2009, memorandum entitled ``Guidance on SIP Elements
Required Under Section 110(a)(1) and (2) for the 2006 24-Hour Fine
Particle (PM2.5) National Ambient Air Quality Standards.''
---------------------------------------------------------------------------
\1\ Two elements identified in section 110(a)(2) are not
governed by the three year submission deadline of section 110(a)(1)
because SIPs incorporating necessary local nonattainment area
controls are not due within three years after promulgation of a new
or revised NAAQS, but rather due at the time the nonattainment area
plan requirements are due pursuant to section 172. These
requirements are: (1) Submissions required by section 110(a)(2)(C)
to the extent that subsection refers to a permit program as required
in part D Title I of the CAA, and (2) submissions required by
section 110(a)(2)(I) which pertain to the nonattainment planning
requirements of part D, Title I of the CAA. Today's proposed
rulemaking does not address infrastructure elements related to
section 110(a)(2)(I) but does provide detail on how South Carolina's
SIP addresses 110(a)(2)(C).
---------------------------------------------------------------------------
110(a)(2)(A): Emission limits and other control measures.
110(a)(2)(B): Ambient air quality monitoring/data system.
110(a)(2)(C): Program for enforcement of control
measures.\2\
---------------------------------------------------------------------------
\2\ This rulemaking only addresses requirements for this element
as they relate to attainment areas.
---------------------------------------------------------------------------
110(a)(2)(D): Interstate transport.\3\
---------------------------------------------------------------------------
\3\ Today's proposed rule does not address element
110(a)(2)(D)(i) (Interstate Transport) for the 1997 and 2006
PM2.5 NAAQS. Interstate transport requirements were
formerly addressed by South Carolina consistent with the Clean Air
Interstate Rule (CAIR). On December 23, 2008, CAIR was remanded by
the DC Circuit Court of Appeals, without vacatur, back to EPA. See
North Carolina v. EPA, 531 F.3d 896 (DC Cir. 2008). Prior to this
remand, EPA took final action to approve South Carolina SIP
revision, which was submitted to comply with CAIR. See 72 FR 57209
(October 9, 2007). In so doing, South Carolina CAIR SIP revision
addressed the interstate transport provisions in section
110(a)(2)(D)(i) for the 1997 and 2006 PM2.5 NAAQS. In
response to the remand of CAIR, EPA has recently finalized a new
rule to address the interstate transport of nitrogen oxides
(NOX) and sulfur dioxide (SO2) in the eastern
United States. See 76 FR 48208 (August 8, 2011) (``the Transport
Rule''). That rule was recently stayed by the DC Circuit Court of
Appeals. EPA's action on element 110(a)(2)(D)(i) will be addressed
in a separate action.
---------------------------------------------------------------------------
110(a)(2)(E): Adequate resources.
110(a)(2)(F): Stationary source monitoring system.
110(a)(2)(G): Emergency power.
110(a)(2)(H): Future SIP revisions.
110(a)(2)(I): Areas designated nonattainment and meet the
applicable requirements of part D.\4\
---------------------------------------------------------------------------
\4\ This requirement was inadvertently omitted from EPA's
October 2, 2007, memorandum entitled ``Guidance on SIP Elements
Required Under Section 110(a)(1) and (2) for the 1997 8-Hour Ozone
and PM2.5 National Ambient Air Quality Standards,'' and
the September 25, 2009, memorandum entitled ``Guidance on SIP
Elements Required Under Section 110(a)(1) and (2) for the 2006 Fine
Particle (PM2.5) National Ambient Air Quality
Standards,'' but as mentioned above is not relevant to today's
proposed rulemaking.
---------------------------------------------------------------------------
110(a)(2)(J): Consultation with government officials;
public notification; and PSD and visibility protection.
110(a)(2)(K): Air quality modeling/data.
110(a)(2)(L): Permitting fees.
110(a)(2)(M): Consultation/participation by affected local
entities.
III. Scope of Infrastructure SIPs
EPA is currently acting upon SIPs that address the infrastructure
requirements of CAA section 110(a)(1) and (2) for ozone and
PM2.5 NAAQS for various states across the country.
Commenters on EPA's recent proposals for some states raised concerns
about EPA statements that it was not addressing certain substantive
issues in the context of acting on those infrastructure SIP
submissions.\5\ Those Commenters specifically raised concerns involving
provisions in existing SIPs and with EPA's statements in other
proposals that it would address two issues separately and not as part
of actions on the infrastructure SIP submissions: (i) Existing
provisions related to excess emissions during periods of start-up,
shutdown, or malfunction at sources (SSM), that may be contrary to the
CAA and EPA's policies addressing such excess emissions; and (ii)
existing provisions related to ``director's variance'' or ``director's
discretion'' that purport to permit revisions to SIP approved emissions
limits with limited public process or without requiring further
approval by EPA, that may be contrary to the CAA (director's
discretion). EPA notes that there are two other substantive issues for
which EPA likewise stated in other proposals that it would address
separately: (i) Existing provisions for minor source new source review
programs that may be inconsistent with the requirements of the CAA and
EPA's regulations that pertain to such programs (minor source NSR); and
(ii) existing provisions for Prevention of Significant Deterioration
(PSD) programs that may be inconsistent with current requirements of
EPA's ``Final NSR Improvement Rule,'' 67 FR 80186 (December 31, 2002),
as amended by 72 FR 32526 (June 13, 2007) (``NSR Reform''). In light of
the comments, EPA believes that its statements in various proposed
actions on infrastructure SIPs with respect to these four individual
issues should be explained in greater depth. It is important to
emphasize that EPA is taking the same position with respect to these
four substantive issues in this action on the infrastructure SIPs for
the 1997 and 2006 PM2.5 NAAQS from South Carolina.
---------------------------------------------------------------------------
\5\ See Comments of Midwest Environmental Defense Center, dated
May 31, 2011. Docket EPA-R05-OAR-2007-1179 (adverse
comments on proposals for three states in Region 5). EPA notes that
these public comments on another proposal are not relevant to this
rulemaking and do not have to be directly addressed in this
rulemaking. EPA will respond to these comments in the appropriate
rulemaking action to which they apply.
---------------------------------------------------------------------------
EPA intended the statements in the other proposals concerning these
four issues merely to be informational, and to provide general notice
of the potential existence of provisions within the existing SIPs of
some states that might require future corrective action. EPA did not
want states, regulated entities, or members of the public to be under
the misconception that the Agency's approval of the infrastructure SIP
submission of a given state should be interpreted as a re-approval of
certain types of provisions that might exist buried in the larger
existing SIP for such state. Thus, for example, EPA explicitly noted
that the Agency believes that some states may have existing SIP
approved SSM provisions that are contrary to the CAA and EPA policy,
but that ``in this rulemaking, EPA is not proposing to approve or
disapprove any existing state provisions with regard to excess
emissions during SSM of operations at facilities.'' EPA further
explained, for informational purposes, that ``EPA plans to address such
State regulations in the future.'' EPA made similar statements, for
similar reasons, with respect to the director's discretion,
[[Page 33375]]
minor source NSR, and NSR Reform issues. EPA's objective was to make
clear that approval of an infrastructure SIP for these ozone and
PM2.5 NAAQS should not be construed as explicit or implicit
re-approval of any existing provisions that relate to these four
substantive issues. EPA is reiterating that position in this action on
the infrastructure SIP for South Carolina.
Unfortunately, the Commenters and others evidently interpreted
these statements to mean that EPA considered action upon the SSM
provisions and the other three substantive issues to be integral parts
of acting on an infrastructure SIP submission, and therefore that EPA
was merely postponing taking final action on the issues in the context
of the infrastructure SIPs. This was not EPA's intention. To the
contrary, EPA only meant to convey its awareness of the potential for
certain types of deficiencies in existing SIPs, and to prevent any
misunderstanding that it was reapproving any such existing provisions.
EPA's intention was to convey its position that the statute does not
require that infrastructure SIPs address these specific substantive
issues in existing SIPs and that these issues may be dealt with
separately, outside the context of acting on the infrastructure SIP
submission of a state. To be clear, EPA did not mean to imply that it
was not taking a full final agency action on the infrastructure SIP
submission with respect to any substantive issue that EPA considers to
be a required part of acting on such submissions under section 110(k)
or under section 110(c). Given the confusion evidently resulting from
EPA's statements in those other proposals, however, we want to explain
more fully the Agency's reasons for concluding that these four
potential substantive issues in existing SIPs may be addressed
separately from actions on infrastructure SIP submissions.
The requirement for the SIP submissions at issue arises out of CAA
section 110(a)(1). That provision requires that states must make a SIP
submission ``within 3 years (or such shorter period as the
Administrator may prescribe) after the promulgation of a national
primary ambient air quality standard (or any revision thereof)'' and
that these SIPs are to provide for the ``implementation, maintenance,
and enforcement'' of such NAAQS. Section 110(a)(2) includes a list of
specific elements that ``[e]ach such plan'' submission must meet. EPA
has historically referred to these particular submissions that states
must make after the promulgation of a new or revised NAAQS as
``infrastructure SIPs.'' This specific term does not appear in the
statute, but EPA uses the term to distinguish this particular type of
SIP submission designed to address basic structural requirements of a
SIP from other types of SIP submissions designed to address other
different requirements, such as ``nonattainment SIP'' submissions
required to address the nonattainment planning requirements of part D,
``regional haze SIP'' submissions required to address the visibility
protection requirements of CAA section 169A, new source review
permitting program submissions required to address the requirements of
part D, and a host of other specific types of SIP submissions that
address other specific matters.
Although section 110(a)(1) addresses the timing and general
requirements for these infrastructure SIPs, and section 110(a)(2)
provides more details concerning the required contents of these
infrastructure SIPs, EPA believes that many of the specific statutory
provisions are facially ambiguous. In particular, the list of required
elements provided in section 110(a)(2) contains a wide variety of
disparate provisions, some of which pertain to required legal
authority, some of which pertain to required substantive provisions,
and some of which pertain to requirements for both authority and
substantive provisions.\6\ Some of the elements of section 110(a)(2)
are relatively straightforward, but others clearly require
interpretation by EPA through rulemaking, or recommendations through
guidance, in order to give specific meaning for a particular NAAQS.\7\
---------------------------------------------------------------------------
\6\ For example, section 110(a)(2)(E) provides that states must
provide assurances that they have adequate legal authority under
state and local law to carry out the SIP; section 110(a)(2)(C)
provides that states must have a substantive program to address
certain sources as required by part C of the CAA; section
110(a)(2)(G) provides that states must have both legal authority to
address emergencies and substantive contingency plans in the event
of such an emergency.
\7\ For example, section 110(a)(2)(D)(i) requires EPA to be sure
that each state's implementation plan contains adequate provisions
to prevent significant contribution to nonattainment of the NAAQS in
other states. This provision contains numerous terms that require
substantial rulemaking by EPA in order to determine such basic
points as what constitutes significant contribution. See ``Rule To
Reduce Interstate Transport of Fine Particulate Matter and Ozone
(Clean Air Interstate Rule); Revisions to Acid Rain Program;
Revisions to the NOx SIP Call; Final Rule,'' 70 FR 25162 (May 12,
2005) (defining, among other things, the phrase ``contribute
significantly to nonattainment'').
---------------------------------------------------------------------------
Notwithstanding that section 110(a)(2) provides that ``each'' SIP
submission must meet the list of requirements therein, EPA has long
noted that this literal reading of the statute is internally
inconsistent, insofar as section 110(a)(2)(I) pertains to nonattainment
SIP requirements that could not be met on the schedule provided for
these SIP submissions in section 110(a)(1).\8\ This illustrates that
EPA must determine which provisions of section 110(a)(2) may be
applicable for a given infrastructure SIP submission. Similarly, EPA
has previously decided that it could take action on different parts of
the larger, general ``infrastructure SIP'' for a given NAAQS without
concurrent action on all subsections, such as section 110(a)(2)(D)(i),
because the Agency bifurcated the action on these latter ``interstate
transport'' provisions within section 110(a)(2) and worked with states
to address each of the four prongs of section 110(a)(2)(D)(i) with
substantive administrative actions proceeding on different tracks with
different schedules.\9\ This illustrates that EPA may conclude that
subdividing the applicable requirements of section 110(a)(2) into
separate SIP actions may sometimes be appropriate for a given NAAQS
where a specific substantive action is necessitated, beyond a mere
submission addressing basic structural aspects of the state's
implementation plans. Finally, EPA notes that not every element of
section 110(a)(2) would be relevant, or as relevant, or relevant in the
same way, for each new or revised NAAQS and the attendant
infrastructure SIP submission for that NAAQS. For example, the
monitoring requirements that might be necessary for purposes of section
110(a)(2)(B) for one NAAQS could be very different than what might be
necessary for a different pollutant. Thus, the content of an
infrastructure SIP submission to meet this element from a state might
be very different for an entirely new NAAQS, versus a minor revision to
an existing NAAQS.\10\
---------------------------------------------------------------------------
\8\ See Id., 70 FR 25162, at 63-65 (May 12, 2005) (explaining
relationship between timing requirement of section 110(a)(2)(D)
versus section 110(a)(2)(I)).
\9\ EPA issued separate guidance to states with respect to SIP
submissions to meet section 110(a)(2)(D)(i) for the 1997 ozone and
1997 PM2.5 NAAQS. See ``Guidance for State Implementation
Plan (SIP) Submissions To Meet Current Outstanding Obligations Under
Section 110(a)(2)(D)(i) for the 8-Hour Ozone and PM2.5
National Ambient Air Quality Standards,'' from William T. Harnett,
Director, Air Quality Policy Division OAQPS, to Regional Air
Division Director, Regions I-X, dated August 15, 2006.
\10\ For example, implementation of the 1997 PM2.5
NAAQS required the deployment of a system of new monitors to measure
ambient levels of that new indicator species for the new NAAQS.
---------------------------------------------------------------------------
Similarly, EPA notes that other types of SIP submissions required
under the statute also must meet the requirements
[[Page 33376]]
of section 110(a)(2), and this also demonstrates the need to identify
the applicable elements for other SIP submissions. For example,
nonattainment SIPs required by part D likewise have to meet the
relevant subsections of section 110(a)(2) such as section 110(a)(2)(A)
or (E). By contrast, it is clear that nonattainment SIPs would not need
to meet the portion of section 110(a)(2)(C) that pertains to part C,
i.e., the PSD requirements applicable in attainment areas.
Nonattainment SIPs required by part D also would not need to address
the requirements of section 110(a)(2)(G) with respect to emergency
episodes, as such requirements would not be limited to nonattainment
areas. As this example illustrates, each type of SIP submission may
implicate some subsections of section 110(a)(2) and not others.
Given the potential for ambiguity of the statutory language of
section 110(a)(1) and (2), EPA believes that it is appropriate for EPA
to interpret that language in the context of acting on the
infrastructure SIPs for a given NAAQS. Because of the inherent
ambiguity of the list of requirements in section 110(a)(2), EPA has
adopted an approach in which it reviews infrastructure SIPs against
this list of elements ``as applicable.'' In other words, EPA assumes
that Congress could not have intended that each and every SIP
submission, regardless of the purpose of the submission or the NAAQS in
question, would meet each of the requirements, or meet each of them in
the same way. EPA elected to use guidance to make recommendations for
infrastructure SIPs for these ozone and PM2.5 NAAQS.
On October 2, 2007, EPA issued guidance making recommendations for
the infrastructure SIP submissions for both the 1997 8-hour ozone NAAQS
and the 1997 PM2.5 NAAQS.\11\ Within this guidance document,
EPA described the duty of states to make these submissions to meet what
the Agency characterized as the ``infrastructure'' elements for SIPs,
which it further described as the ``basic SIP requirements, including
emissions inventories, monitoring, and modeling to assure attainment
and maintenance of the standards.'' \12\ As further identification of
these basic structural SIP requirements, ``attachment A'' to the
guidance document included a short description of the various elements
of section 110(a)(2) and additional information about the types of
issues that EPA considered germane in the context of such
infrastructure SIPs. EPA emphasized that the description of the basic
requirements listed on attachment A was not intended ``to constitute an
interpretation of'' the requirements, and was merely a ``brief
description of the required elements.'' \13\ EPA also stated its belief
that with one exception, these requirements were ``relatively self
explanatory, and past experience with SIPs for other NAAQS should
enable States to meet these requirements with assistance from EPA
Regions.'' \14\ However, for the one exception to that general
assumption (i.e., how states should proceed with respect to the
requirements of section 110(a)(2)(G) for the 1997 PM2.5
NAAQS), EPA gave much more specific recommendations. But for other
infrastructure SIP submittals, and for certain elements of the
submittals for the 1997 PM2.5 NAAQS, EPA assumed that each
State would work with its corresponding EPA regional office to refine
the scope of a State's submittal based on an assessment of how the
requirements of section 110(a)(2) should reasonably apply to the basic
structure of the State's implementation plans for the NAAQS in
question.

110(a)(1) and (2) for the 1997 8-hour Ozone and PM2.5
National Ambient Air Quality Standards,'' from William T. Harnett,
Director, Air Quality Policy Division, to Air Division Directors,
Regions I-X, dated October 2, 2007 (the ``2007 Guidance'').
\12\ Id., at page 2.
\13\ Id., at attachment A, page 1.
\14\ Id., at page 4. In retrospect, the concerns raised by the
Commenters with respect to EPA's approach to some substantive issues
indicates that the statute is not so ``self explanatory,'' and
indeed is sufficiently ambiguous that EPA needs to interpret it in
order to explain why these substantive issues do not need to be
addressed in the context of infrastructure SIPs and may be addressed
at other times and by other means.
---------------------------------------------------------------------------
On September 25, 2009, EPA issued guidance to make recommendations
to states with respect to the infrastructure SIPs for the 2006
PM2.5 NAAQS.\15\ In the 2009 Guidance, EPA addressed a
number of additional issues that were not germane to the infrastructure
SIPs for the 1997 8-hour ozone and 1997 PM2.5 NAAQS, but
were germane to these SIP submissions for the 2006 PM2.5
NAAQS (e.g., the requirements of section 110(a)(2)(D)(i) that EPA had
bifurcated from the other infrastructure elements for those specific
1997 ozone and PM2.5 NAAQS). Significantly, neither the 2007
Guidance nor the 2009 Guidance explicitly referred to the SSM,
director's discretion, minor source NSR, or NSR Reform issues as among
specific substantive issues EPA expected states to address in the
context of the infrastructure SIPs, nor did EPA give any more specific
recommendations with respect to how states might address such issues
even if they elected to do so. The SSM and director's discretion issues
implicate section 110(a)(2)(A), and the minor source NSR and NSR Reform
issues implicate section 110(a)(2)(C). In the 2007 Guidance and the
2009 Guidance, however, EPA did not indicate to states that it intended
to interpret these provisions as requiring a substantive submission to
address these specific issues in existing SIP provisions in the context
of the infrastructure SIPs for these NAAQS. Instead, EPA's 2007
Guidance merely indicated its belief that the states should make
submissions in which they established that they have the basic SIP
structure necessary to implement, maintain, and enforce the NAAQS. EPA
believes that states can establish that they have the basic SIP
structure, notwithstanding that there may be potential deficiencies
within the existing SIP. Thus, EPA's proposals for other states
mentioned these issues not because the Agency considers them issues
that must be addressed in the context of an infrastructure SIP as
required by section 110(a)(1) and (2), but rather because EPA wanted to
be clear that it considers these potential existing SIP problems as
separate from the pending infrastructure SIP actions. The same holds
true for this action on the infrastructure SIPs for South Carolina.
---------------------------------------------------------------------------
\15\ See ``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),''
from William T, Harnett, Director, Air Quality Policy Division, to
Regional Air Division Directors, Regions I-X, dated September 25,
2009 (the ``2009 Guidance'').
---------------------------------------------------------------------------
EPA believes that this approach to the infrastructure SIP
requirement is reasonable because it would not be feasible to read
section 110(a)(1) and (2) to require a top to bottom, stem to stern,
review of each and every provision of an existing SIP merely for
purposes of assuring that the state in question has the basic
structural elements for a functioning SIP for a new or revised NAAQS.
Because SIPs have grown by accretion over the decades as statutory and
regulatory requirements under the CAA have evolved, they may include
some outmoded provisions and historical artifacts that, while not fully
up to date, nevertheless may not pose a significant problem for the
purposes of ``implementation, maintenance, and enforcement'' of a new
or revised NAAQS when EPA considers the overall effectiveness of the
SIP. To the contrary, EPA believes that a better approach is for EPA to
determine which specific SIP elements from section 110(a)(2) are
applicable to an infrastructure SIP for a given NAAQS, and to focus
attention on those elements that are most likely to
[[Page 33377]]
need a specific SIP revision in light of the new or revised NAAQS.
Thus, for example, EPA's 2007 Guidance specifically directed states to
focus on the requirements of section 110(a)(2)(G) for the 1997
PM2.5 NAAQS because of the absence of underlying EPA
regulations for emergency episodes for this NAAQS and an anticipated
absence of relevant provisions in existing SIPs.
Finally, EPA believes that its approach is a reasonable reading of
section 110(a)(1) and (2) because the statute provides other avenues
and mechanisms to address specific substantive deficiencies in existing
SIPs. These other statutory tools allow the Agency to take appropriate
tailored action, depending upon the nature and severity of the alleged
SIP deficiency. Section 110(k)(5) authorizes EPA to issue a ``SIP
call'' whenever the Agency determines that a state's SIP is
substantially inadequate to attain or maintain the NAAQS, to mitigate
interstate transport, or otherwise to comply with the CAA.\16\ Section
110(k)(6) authorizes EPA to correct errors in past actions, such as
past approvals of SIP submissions.\17\ Significantly, EPA's
determination that an action on the infrastructure SIP is not the
appropriate time and place to address all potential existing SIP
problems does not preclude the Agency's subsequent reliance on
provisions in section 110(a)(2) as part of the basis for action at a
later time. For example, although it may not be appropriate to require
a state to eliminate all existing inappropriate director's discretion
provisions in the course of acting on the infrastructure SIP, EPA
believes that section 110(a)(2)(A) may be among the statutory bases
that the Agency cites in the course of addressing the issue in a
subsequent action.\18\
---------------------------------------------------------------------------
\16\ EPA has recently issued a SIP call to rectify a specific
SIP deficiency related to the SSM issue. See, ``Finding of
Substantial Inadequacy of Implementation Plan; Call for Utah State
Implementation Plan Revision,'' 74 FR 21639 (April 18, 2011).
\17\ EPA has recently utilized this authority to correct errors
in past actions on SIP submissions related to PSD programs. See
``Limitation of Approval of Prevention of Significant Deterioration
Provisions Concerning Greenhouse Gas Emitting-Sources in State
Implementation Plans; Final Rule,'' 75 FR 82536 (December 30, 2010).
EPA has previously used its authority under CAA 110(k)(6) to remove
numerous other SIP provisions that the Agency determined it had
approved in error. See 61 FR 38664 (July 25, 1996) and 62 FR 34641
(June 27, 1997) (corrections to American Samoa, Arizona, California,
Hawaii, and Nevada SIPs); 69 FR 67062 (November 16, 2004)
(corrections to California SIP); and 74 FR 57051 (November 3, 2009)
(corrections to Arizona and Nevada SIPs).
\18\ EPA has recently disapproved a SIP submission from Colorado
on the grounds that it would have included a director's discretion
provision inconsistent with CAA requirements, including section
110(a)(2)(A). See 75 FR 42342, 42344 (July 21, 2010) (proposed
disapproval of director's discretion provisions); 76 FR 4540
(January 26, 2011) (final disapproval of such provisions).
---------------------------------------------------------------------------
IV. What is EPA's analysis of how South Carolina addressed the elements
of sections 110(a)(1) and (2) ``Infrastructure'' provisions?
South Carolina's infrastructure submission addresses the provisions
of sections 110(a)(1) and (2) as described below.
1. 110(a)(2)(A): Emission limits and other control measures: South
Carolina's infrastructure submissions provide an overview of the
provisions of the South Carolina's Air Pollution Control Requirements
relevant to air quality control regulations. The regulations listed
below have been federally approved in the South Carolina SIP and
include enforceable emission limitations and other control measures:
Regulation 61-62.1--Definitions, Permit Requirements, and
Emissions Inventory;
Regulation 61-62.2--Prohibition of Open Burning;
Regulation 61-62.5--Standard No. 1, Emissions form Fuel
Burning Operations; Standard No. 2, Ambient Air Quality Standards; and
Standard No. 4, Emission from Process Industries; Standard No. 6,
Alternative Emissions Limitation Options;
Regulation 61-62.6-- Control of Fugitive Particulate
Matter; and,
Regulation 61-30--(state-only regulation)--Environmental
Protection Fees.
EPA has made the preliminary determination that the provisions
contained in these chapters and South Carolina's practices are adequate
to protect the PM2.5 annual and 24-hour NAAQS in the State.
In this action, EPA is not proposing to approve or disapprove any
existing state provisions with regard to excess emissions during SSM of
operations at a facility. EPA believes that a number of states have SSM
provisions which are contrary to the CAA and existing EPA guidance,
``State Implementation Plans: Policy Regarding Excess Emissions During
Malfunctions, Startup, and Shutdown'' (September 20, 1999), and the
Agency plans to address such state regulations in the future. In the
meantime, EPA encourages any state having deficient SSM provisions to
take steps to correct it as soon as possible.
Additionally, in this action, EPA is not proposing to approve or
disapprove any existing state rules with regard to director's
discretion or variance provisions. EPA believes that a number of states
have such provisions which are contrary to the CAA and existing EPA
guidance (52 FR 45109 (November 24, 1987)), and the Agency plans to
take action in the future to address such state regulations. In the
meantime, EPA encourages any state having a director's discretion or
variance provision which is contrary to the CAA and EPA guidance to
take steps to correct the deficiency as soon as possible.
2. 110(a)(2)(B) Ambient air quality monitoring/data system: South
Carolina's Regulation 61-62.1, Section II, Permit Requirements, and
Section IV, Source Tests, along with the South Carolina Network
Description and Ambient Air Monitoring Network Plan, provide for an
ambient air quality monitoring system in the State. Annually, EPA
approves the ambient air monitoring network plan for the state
agencies. On July 18, 2011, South Carolina submitted its plan to EPA.
On October 12, 2011, EPA approved South Carolina's monitoring network
plan. South Carolina's approved monitoring network plan can be accessed
at www.regulations.gov using Docket ID No. EPA-R04-OAR-2012-0238. EPA
has made the preliminary determination that South Carolina's SIP and
practices are adequate for the ambient air quality monitoring and data
systems related to the 1997 annual and 2006 24-hour PM2.5
NAAQS.
3. 110(a)(2)(C) Program for enforcement of control measures
including review of proposed new sources: The regulations described
below have been federally approved in the South Carolina SIP and
pertain to the construction or modification of any major stationary
source in areas designated as attainment, nonattainment or
unclassifiable:
Regulation 61-62.1, Section II, Permit Requirements;
Regulation 61-62.5, Standard No. 7, Prevention of
Significant Deterioration; and,
Regulation 61-62.5, Standard No. 7.1, Nonattainment New
Source Review.
South Carolina's SIP is current with regard to PSD requirements.\19\ On
June 23, 2011, EPA approved several revisions to South Carolina's SIP
to
[[Page 33378]]
update requirements for the State's PSD program. See 76 FR 36875.
---------------------------------------------------------------------------
\19\ On June 11, 2010, the South Carolina Governor signed an
Executive Order to confirm that the State had authority to implement
appropriate emission thresholds for determining which new stationary
sources and modification projects become subject to PSD permitting
requirements for their Greenhouse Gas emissions at the state level.
A copy of the Executive Order and a letter of clarification can be
accessed at www.regulations.gov using Docket ID No. EPA-R04-OAR-
2012-0238.
---------------------------------------------------------------------------
In this action, EPA is proposing to approve South Carolina's
infrastructure SIP for the 1997 annual and 2006 24-hour
PM2.5 NAAQS with respect to the general requirement in
section 110(a)(2)(C) to include a program in the SIP that regulates the
modification and construction of any stationary source as necessary to
assure that the NAAQS are achieved. EPA is not proposing to approve or
disapprove the State's existing minor NSR program itself to the extent
that it is inconsistent with EPA's regulations governing this program.
EPA believes that a number of states may have minor NSR provisions that
are contrary to the existing EPA regulations for this program. EPA
intends to work with states to reconcile state minor NSR programs with
EPA's regulatory provisions for the program. The statutory requirements
of section 110(a)(2)(C) provide for considerable flexibility in
designing minor NSR programs, and EPA believes it may be time to
revisit the regulatory requirements for this program to give the states
an appropriate level of flexibility to design a program that meets
their particular air quality concerns, while assuring reasonable
consistency across the country in protecting the NAAQS with respect to
new and modified minor sources.
EPA has made the preliminary determination that South Carolina's
SIP and practices are adequate for program enforcement of control
measures including review of proposed new sources related to the 1997
annual and 2006 24-hour PM2.5 NAAQS.
4. 110(a)(2)(D)(ii) Interstate and International transport
provisions: Regulation 61-62.5 Standard 7, Prevention of Significant
Deterioration, outlines how the State will notify neighboring states of
potential impacts from new or modified sources. South Carolina does not
have any pending obligation under sections 115 and 126 of the CAA. EPA
has made the preliminary determination that South Carolina's SIP and
practices are adequate for insuring compliance with the applicable
requirements relating to interstate and international pollution
abatement for the 1997 annual and 2006 24-hour PM2.5 NAAQS.
5. 110(a)(2)(E) Adequate resources: Section 110(a)(2)(E) requires
that each implementation plan provide (i) necessary assurances that the
State will have adequate personnel, funding, and authority under state
law to carry out its implementation plan, (ii) that the State comply
with the requirements respecting State Boards pursuant to section 128
of the Act, and (iii) necessary assurances that, where the State has
relied on a local or regional government, agency, or instrumentality
for the implementation of any plan provision, the State has
responsibility for ensuring adequate implementation of such plan
provisions. As with the remainder of the infrastructure elements
addressed by this notice, EPA is proposing to approve South Carolina's
SIP as meeting the requirements of sub-elements 110(a)(2)(E)(i) and
(iii). With respect to 110(a)(2)(E)(ii) (regarding state boards), South
Carolina's submission is being addressed in a separate action. EPA's
rationale for today's proposals respecting sub-elements (i) and (iii)
is described in turn below.
In support of EPA's proposal to approve sub-elements
110(a)(2)(E)(i) and (iii), DHEC's legal authority to establish SIPs and
implement related plans, in general, is prescribed in S.C. Code Ann.
Title 48, Chapter 1, Pollution Control Act. Specifically, S.C. Code
Ann. Section 48-1-50(12) grants DHEC the statutory authority to
``[a]ccept, receive and administer grants or other funds or gifts for
the purpose of carrying out any of the purposes of this chapter;
accept, receive and receipt for Federal money given by the Federal
government under any Federal law to the State of South Carolina for air
or water control activities, surveys or programs * * *.'' S.C. Code
Ann. Title 48, Chapter 2, Environmental Protection Funds, grants DHEC
statutory authority to establish environmental protection funds.
Additionally, Regulation 61-30, Environmental Protection Fees, provides
DHEC with the ability to access fees for environmental permitting
programs. In addition, the requirements of 110(a)(2)(E)(i) and
110(a)(2)(E)(iii) are met when EPA performs a completeness
determination for each SIP submittal. This determination ensures that
each submittal provides evidence that adequate personnel, funding, and
legal authority under State Law has been used to carry out the state's
implementation plan and related issues. South Carolina's authority is
included in all prehearings and final SIP submittal packages for
approval by EPA.
Annually, states update grant commitments based on current SIP
requirements, air quality planning, and applicable requirements related
to the NAAQS, including 1997 annual and 2006 24-hour PM2.5
NAAQS. On March 8, 2012, EPA submitted a letter to South Carolina
outlining 105 grant commitments and current status for fiscal year
2011. The letter EPA submitted to South Carolina can be accessed at
www.regulations.gov using Docket ID No. EPA-R04-OAR-2012-0238. There
were no outstanding issues, therefore South Carolina's grants were
finalized and closed out. EPA has made the preliminary determination
that South Carolina has adequate resources for implementation of the
1997 annual and 2006 24-hour PM2.5 NAAQS.
Section 110(a)(2)(E)(ii) requires that the state comply with
section 128 of the CAA. Section 128 requires that: (1) The majority of
members of the state body which approves permits or enforcement orders
represent the public interest and do not derive any significant portion
of their income from persons subject to permitting or enforcement
orders under the CAA; and (2) any potential conflicts of interest by
such body be adequately disclosed. As stated above section
110(a)(2)(E)(ii) is being addressed in a separate action.
6. 110(a)(2)(F) Stationary source monitoring system: Regulation 61-
62.1, Definitions and General Requirements, Section III--Emissions
Inventory, of the South Carolina SIP provides for an emission inventory
plan that establishes reporting requirements. DHEC uses this data to
track progress towards maintaining the NAAQS, develop control and
maintenance strategies, identify sources and general emission levels,
and determine compliance with emission regulations and additional EPA
requirements.
Additionally, South Carolina is required to submit emissions data
to EPA for purposes of the National Emissions Inventory (NEI). The NEI
is EPA's central repository for air emissions data. EPA published the
Air Emissions Reporting Rule (AERR) on December 5, 2008, which modified
the requirements for collecting and reporting air emissions data (73 FR
76539). The AERR shortened the time states had to report emissions data
from 17 to 12 months, giving states one calendar year to submit
emissions data. All states are required to submit a comprehensive
emissions inventory every three years and report emissions for certain
larger sources annually through EPA's online Emissions Inventory System
(EIS). States report emissions data for the six criteria pollutants and
the precursors that form them--NOX, SO2, ammonia,
lead, carbon monoxide, particulate matter, and volatile organic
compounds (VOCs). Many states also voluntarily report emissions of
hazardous air pollutants. South Carolina made its latest update to the
NEI on December 21, 2011. EPA compiles the emissions data,
supplementing it where necessary, and releases it to the general public
through
[[Page 33379]]
the Web site http://www.epa.gov/ttn/chief/eiinformation.html. EPA has
made the preliminary determination that South Carolina's SIP and
practices are adequate for the stationary source monitoring systems
related to the 1997 annual and 2006 24-hour PM2.5 NAAQS.
7. 110(a)(2)(H) Future SIP revisions: As previously discussed, DHEC
is responsible for adopting air quality rules and revising SIPs as
needed to attain or maintain the NAAQS. South Carolina has the ability
and authority to respond to calls for SIP revisions, and has provided a
number of SIP revisions over the years for implementation of the PM
NAAQS. Specific to the 1997 annual and 2006 24-hour PM2.5
NAAQS, South Carolina has provided the following submissions:
November 19, 2004, SIP Revision--(EPA approval, 72 FR
46903, August 22, 2007) Revisions to Ambient Air Quality Standards;
August 14, 2007, SIP Revision--(EPA approval, 72 FR 57209,
October 9, 2007) Clean Air Interstate Rule;
December 2, 2010, SIP Revision--(EPA approval, 76 FR
36875, June 23, 2011) New Source Review PM2.5; and,
March 14, 2011, SIP Revision--(EPA approval, 76 FR 36875,
June 23, 2011) New Source Review PM2.5.
EPA has made the preliminary determination that South Carolina's
SIP and practices adequately demonstrate a commitment to provide future
SIP revisions related to the 1997 annual and 2006 24-hour
PM2.5 NAAQS when necessary.
8. 110(a)(2)(J) (121 consultation) Consultation with government
officials: South Carolina Air Regulation 61-62.5, Air Pollution Control
Standards, Standard No. 7, Prevention of Significant Deterioration, as
well as the Regional Haze Implementation Plan (which allows for
consultation between appropriate state, local, and tribal air pollution
control agencies as well as the corresponding Federal Land Managers),
provide for consultation with government officials whose jurisdictions
might be affected by SIP development activities. More specifically,
South Carolina adopted state-wide consultation procedures for the
implementation of transportation conformity which includes the
consideration of the development of mobile inventories for SIP
development. Required partners covered by South Carolina's consultation
procedures include federal, state and local transportation and air
quality agency officials. EPA approved South Carolina's consultation
procedures on July 28, 2009 (See 74 FR 37168). EPA has made the
preliminary determination that South Carolina's SIP and practices
adequately demonstrate consultation with government officials related
to the 1997 annual and 2006 24-hour PM2.5 NAAQS when
necessary.
9. 110(a)(2)(J) (127 public notification) Public notification: DHEC
has several public notice mechanisms in place to notify the public of
PM2.5 and other pollutant forecasting, including an air
quality monitoring Web site. South Carolina also has an extensive
outreach program to educate the public and promote the use of voluntary
emissions reduction measures. Such outreach programs include the
State's open burning awareness program. In addition DHEC has produced
public education materials including factsheets on the following
topics: PM generally including a link to EPA PM Web page, ``How smoke
from fires can affect your health, ``Particle pollution and your
health'' and ``Protect your lungs from wildlife smoke.'' Regulation 61-
62.3, Air Pollution Episodes, requires that DHEC notify the public of
any air pollution episode or NAAQS violation. EPA has made the
preliminary determination that South Carolina's SIP and practices
adequately demonstrate the State's ability to provide public
notification related to the 1997 annual and 2006 24-hour
PM2.5 NAAQS when necessary.
10. 110(a)(2)(J) (PSD) PSD and visibility protection: South
Carolina demonstrates its authority to regulate new and modified
sources of PM to assist in the protection of air quality in Regulation
61-62.1, Definitions and General Requirements, Section II, Permit
Resources, and Regulation 61-62.5, Air Pollution Control Standards,
Standard No. 7, Prevention of Significant Deterioration, and 7.1,
Nonattainment New Source Review. South Carolina's SIP is current with
regard to PSD requirements. On June 23, 2011, EPA approved several
revisions to South Carolina's SIP to update requirements for the
State's PSD program. See 76 FR 36875.
With regard to the applicable requirements for visibility
protection, EPA recognizes that states are subject to visibility and
regional haze program requirements under Part C of the Act (which
includes sections 169A and 169B). In the event of the establishment of
a new NAAQS, however, the visibility and regional haze program
requirements under part C do not change. Thus, EPA finds that there is
no new visibility obligation ``triggered'' under section 110(a)(2)(J)
when a new NAAQS becomes effective. This would be the case even in the
event a secondary PM2.5 NAAQS for visibility is established,
because this NAAQS would not affect visibility requirements under part
C. South Carolina has submitted SIP revisions for approval to satisfy
the requirements of the CAA Section 169A, and the regional haze and
best available retrofit technology rules contained in 40 CFR 51.308.
These revisions are currently under review and will be acted on in a
separate action. EPA has made the preliminary determination that South
Carolina's SIP and practices adequately demonstrate the State's ability
to implement PSD programs and to provide for visibility protection
related to the 1997 annual and 2006 24-hour PM2.5 NAAQS when
necessary.
11. 110(a)(2)(K) Air quality and modeling/data: South Carolina
Regulation 61-62.5, Air Pollution Control Standards, Standards No. 2,
Ambient Air Quality Standards, and No. 7, Prevention of Significant
Deterioration, require that air modeling be conducted to determine
permit applicability. These standards demonstrate that South Carolina
has the authority to provide relevant data for the purpose of
predicting the effect on ambient air quality of the 1997 annual and
2006 24-hour PM2.5 NAAQS. Additionally, South Carolina
supports a regional effort to coordinate the development of emissions
inventories and conduct regional modeling for several NAAQS, including
the 1997 annual and 2006 24-hour PM2.5 NAAQS, for the
Southeastern states. Taken as a whole, South Carolina's air quality
regulations demonstrate that South Carolina has the authority to
provide relevant data for the purpose of predicting the effect on
ambient air quality of the 1997 annual and 2006 24-hour
PM2.5 NAAQS. EPA has made the preliminary determination that
South Carolina's SIP and practices adequately demonstrate the State's
ability to provide for air quality and modeling, along with analysis of
the associated data, related to the 1997 annual and 2006 24-hour
PM2.5 NAAQS when necessary.
12. 110(a)(2)(L) Permitting fees: Pursuant to S.C. Code Ann.
Section 48-2-50, DHEC shall charge fees for environmental programs it
administers pursuant to federal and state law and regulations.
Regulation 61-30, Environmental Protection Fees, prescribes fees
applicable to applicants and holders of permits, licenses,
certificates, certifications, and registrations as well as establishes
procedures for the payment of fees, provides for the assessment of
penalties for nonpayment, and establishes an appeals process for
refuting fees. EPA has made the preliminary determination
[[Page 33380]]
that South Carolina's SIP and practices adequately provide for
permitting fees related to the 1997 annual and 2006 24-hour
PM2.5 NAAQS when necessary.
13. 110(a)(2)(M) Consultation/participation by affected local
entities: Regulation 61-62.5, Air Pollution Control Standards, Standard
No. 7, Prevention of Significant Deterioration, of the South Carolina
SIP requires that DHEC notify the public of the application,
preliminary determination, degree of incremental consumption, and the
opportunity for comment prior to making a final permitting decision.
DHEC has worked closely with local political subdivisions when
developing its Transportation Conformity SIP, Regional Haze
Implementation Plan, Early Action Compacts, and the 8-hour Ozone
Attainment Demonstration for York County, South Carolina portion of the
Charlotte-Gastonia-Rock Hill NC-SC nonattainment area. EPA has made the
preliminary determination that South Carolina's SIP and practices
adequately demonstrate consultation with affected local entities when
necessary.
V. Proposed Action
As described above, DHEC has addressed the elements of the CAA
110(a)(1) and (2) SIP requirements pursuant to EPA's October 2, 2007,
and September 25, 2009, guidance to ensure that the 1997 annual and
2006 24-hour PM2.5 NAAQS are implemented, enforced, and
maintained in South Carolina. EPA is proposing to approve South
Carolina's infrastructure submission for the 1997 annual and 2006 24-
hour PM2.5 NAAQS, specifically 1997 annual and 2006 24-hour
PM2.5 NAAQS for sections 110(a)(2)(A)-(H), (J)-(M), with the
exception of 110(a)(2)(C) the nonattainment area requirements,
110(a)(2)(D)(i), sub-element 110(a)(2)(E)(ii) and 110(a)(2)(G) for
section because its March 14, 2008, and September 18, 2009, submissions
are consistent with section 110 of the CAA.
VI. 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. See 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
proposed 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 proposed action:
Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
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 CAA; 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).
EPA has preliminarily determined that this proposed rule does not have
tribal implications as specified by Executive Order 13175 (65 FR 67249,
November 9, 2000), because there are no ``substantial direct effects''
on an Indian Tribe as a result of this action. The Catawba Indian
Nation Reservation is located within the South Carolina portion of the
bi-state Charlotte nonattainment area. Pursuant to the Catawba Indian
Claims Settlement Act, S.C. Code Ann. 27-16-120, ``all state and local
environmental laws and regulations apply to the Catawba Indian Nation
and Reservation and are fully enforceable by all relevant state and
local agencies and authorities.'' Thus, the South Carolina SIP applies
to the Catawba Reservation. EPA has also preliminarily determined that
these revisions will not impose any substantial direct costs on tribal
governments or preempt tribal law.
