Proposed Rule To Implement the 1997 8-Hour Ozone National Ambient
Air Quality Standard: New Source Review Anti-Backsliding Provisions for
Former 1-Hour Ozone Standard
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: This proposed action would clarify the obligation to retain 1-
hour nonattainment new source review (NSR) program requirements for
certain areas designated nonattainment for the 1997 8-hour ozone
national ambient air quality standard (NAAQS). The EPA proposes to
revise the rule for implementing the 1997 8-hour ozone NAAQS to address
how NSR requirements that applied by virtue of the area's 1-hour ozone
NAAQS classification should apply under the anti-backsliding provisions
of the 1997 8-hour implementation rule. This proposed rule responds to
the ruling by the U.S. Court of Appeals for the District of Columbia
Circuit that the 1-hour major NSR program, as it applies to areas that
were designated 1-hour nonattainment on the date of designation for the
1997 8-hour NAAQS, is a required control to prevent backsliding. EPA
has separately proposed to remove the vacated provisions of the rule
that allowed States to remove (or not include, if not yet adopted) 1-
hour major NSR for nonattainment areas from their State implementation
plans (SIPs).
DATES: Comments. Comments must be received on or before September 23,
2010.
Public Hearing. If anyone contacts us requesting a public hearing
by September 3, 2010, we will hold a public hearing approximately 30
days after publication of this proposal in the Federal Register.
Additional information about the hearing would be published in a
subsequent Federal Register notice.

II. Background for This Proposal
A. Anti-Backsliding Provisions
The EPA codified the anti-backsliding provisions governing the
transition from the revoked 1-hour ozone NAAQS to the 1997 8-hour ozone
NAAQS in 40 CFR 51.905(a) (part of the ``Phase 1 Rule''). These
provisions, as promulgated, retained 13 requirements specified under
section 182 of the Clean Air Act (CAA or Act), as those requirements
applied for the 1-hour ozone standard.\1\ These 13 requirements were
identified as ``applicable requirements'' in the regulation. 40 CFR
51.900(f). The applicable requirements include: (1) Reasonably
available control technology (RACT) for major stationary sources; (2)
vehicle inspection and maintenance (I/M) programs; (3) major source
applicability thresholds for purposes of RACT; (4) rate of progress
reductions; (5) stage II gasoline vehicle refueling vapor recovery; (6)
clean fuels fleet program under section 183(c)(4) of the CAA; (7) clean
fuels for boilers under
[[Page 51962]]
section 182(e)(3) of the CAA; (8) transportation control measures; (9)
enhanced (ambient) monitoring; (10) transportation controls under
section 182(c)(5); (11) vehicle miles traveled provisions; (12)
NOX requirements under section 182(f) of the CAA; and (13)
attainment demonstrations. Under the Phase 1 Rule, these requirements
continue to apply to an area after revocation of the 1-hour NAAQS if
the requirements were applied in the area based on the area's 1-hour
ozone designation and classification as of the effective date of its
1997 8-hour designation (for most areas the effective date of the 1997
8-hour designation was June 15, 2004). 40 CFR 51.900(h).
---------------------------------------------------------------------------
\1\ See Final Rule to Implement the 8-Hour Ozone National
Ambient Air Quality Standard-Phase 1 (69 FR 23951, April 30, 2004).
---------------------------------------------------------------------------
The rule further provides that an area remains subject to these
applicable requirements until the area attains the 1997 8-hour NAAQS.
40 CFR 51.905(b). Additionally, such obligations cannot be removed from
a SIP, even if we redesignate the area to attainment for the 8-hour
NAAQS. However, upon redesignation to attainment of the 8-hour ozone
standard, a State could request that such requirements be moved to the
contingency measures portion of the SIP (40 CFR 51.905(b)).
In the Phase 1 Rule and in two subsequent reconsideration rules
(which are described below), EPA explicitly excluded 1-hour major NSR
from the list of retained applicable requirements (Sec. 51.905(e)).\2\
The Phase 1 Rule provided at Sec. 51.905(e)(4)(i) that when we revoked
the 1-hour standard, the State would no longer be required to retain
the major NSR provisions associated with the 1-hour NAAQS in its SIP
for areas that were designated nonattainment for the 1-hour ozone
standard. Instead, the State could revise its SIP to replace the 1-hour
NSR requirements with those specific to its new 8-hour ozone
designation and classification status. In many cases, this would allow
an area to adopt higher major NSR source applicability thresholds and
lower offset ratios associated with the area's lower 8-hour
classification. This would have the effect of reducing the number of
sources subject to major NSR source requirements, including more
stringent emission limitations and offsets.
---------------------------------------------------------------------------
\2\ Note that if the area is nonattainment for the 1997 8-hour
standard, the CAA requires that nonattainment NSR would apply to the
area based on its classification for the 1997 8-hour standard.
---------------------------------------------------------------------------
The Phase 1 Rule also contained a provision directed specifically
at areas that were designated 8-hour attainment and 1-hour
nonattainment. That provision addressed the applicable requirements
listed in Sec. 51.900(f) as well as 1-hour NSR requirements. With
respect to the 1-hour NSR requirement, Sec. 51.905(a)(3) stated: ``For
such areas, the state may request that the nonattainment NSR provisions
be removed from the SIP on or after the date of revocation of the 1-
hour NAAQS and need not be shifted to contingency measures subject to
paragraph (e)(4) of this section.''
B. Reconsideration of Certain Provisions of the Phase 1 Rule
Following publication of the Phase 1 Rule, the Administrator
received three petitions pursuant to section 307(b)(7)(B) of the CAA
requesting reconsideration of several aspects of the final rule.\3\ EPA
addressed certain issues raised in these petitions in two rulemakings.
In the first reconsideration rulemaking, EPA further clarified the
implementation rule in two respects: (a) CAA section 185 penalty fees
under the 1-hour standard would no longer be applicable after
revocation of the 1-hour standard, and (b) the effective date of
designations under the 1997 8-hour standard (i.e., for almost all
areas, June 15, 2004) is the date for determining which 1-hour control
measures continue to apply in an area once the 1-hour standard is
revoked.\4\ Additionally, EPA clarified that the requirement to retain
1-hour contingency measures for failure to make progress or failure to
attain would no longer apply once we revoked the 1-hour standard.
---------------------------------------------------------------------------
\3\ Petitions for reconsideration of the Phase 1 Rule were filed
by: (1) Earthjustice on behalf of the American Lung Association,
Environmental Defense Fund, Natural Resources Defense Council,
Sierra Club, Clean Air Task Force, Conservation Law Foundation, and
Southern Alliance for Clean Energy; (2) the National Petrochemical
and Refiners Association and the National Association of
Manufacturers; and (3) the American Petroleum Institute, American
Chemistry Council, American Iron and Steel Institute, National
Association of Manufacturers and the U.S. Chamber of Commerce.
\4\ 70 FR 30592 (May 26, 2005).
---------------------------------------------------------------------------
In the second reconsideration rulemaking, we proposed and took
comment on the issue of whether we should interpret the Act to require
8-hour ozone nonattainment areas to retain major NSR requirements that
applied on the basis of the areas' 1-hour ozone nonattainment
classification (70 FR 17018, April 4, 2005). We took final action on
this NSR issue on June 30, 2005 (70 FR 39413, July 8, 2005),
determining not to require States to retain major NSR under the 1-hour
standard once it was revoked.
C. South Coast Decision
In South Coast Air Quality Management District, et al., v. EPA, 472
F.3d 882 (DC Cir. 2006) (South Coast), the Court vacated EPA's waiver
of 1-hour major nonattainment NSR requirements as they apply to the 1-
hour standard and stated that removing them from a SIP ``would
constitute impermissible backsliding.'' The decision was based on
challenges by several parties to EPA's Phase 1 Rule and the two
reconsideration rules. The Court upheld certain challenges and rejected
others, but purported to vacate the Phase 1 Rule in its entirety. South
Coast Air Quality Management District, et al., v. EPA, 472 F.3d 882 (DC
Cir. 2006). The EPA requested rehearing and clarification of the
ruling, and, on June 8, 2007, the Court clarified that it vacated the
rule only to the extent that it had upheld the petitioners' challenges.
South Coast Air Quality Management District, et al., v. EPA, 2007 U.S.
App. LEXIS 13303 (DC Cir. 2007). Thus, the Court vacated the provisions
that waived obligations as they applied under the revoked 1-hour
standard for major nonattainment NSR, CAA section 185 penalty fees, and
contingency measures for failure to attain or to make reasonable
progress toward attainment.
We have separately proposed to remove these provisions from the
regulations at 40 CFR part 51 in order to ensure that the published
regulatory text is consistent with the Court's vacatur. 74 FR 2936
(January 16, 2009). With regard to NSR, the South Coast decision means
that the 1-hour major NSR thresholds and offsets remain applicable to
those areas that had not been redesignated to 1-hour attainment by the
date of designation for the 8-hour ozone NAAQS (except where the area
has since been redesignated to attainment for the 8-hour standard). As
previously stated in the October 3, 2007, memo from Robert J. Meyers to
the Regional Administrators, States are to comply with the South Coast
decision as quickly as possible. States should take appropriate steps
to implement the 1-hour major NSR requirements in accordance with the
South Coast decision without waiting for completion of this rulemaking.
III. This Action
This action proposes regulatory language to clarify the obligation
to retain 1-hour major nonattainment NSR requirements and proposes when
States can request that these requirements be removed from their SIPs.
This proposal focuses on the nonattainment NSR aspects of the South
Coast decision that can be clarified through additions of new rule
language. In a separate action, we have proposed to remove the vacated
regulatory
[[Page 51963]]
provisions in Sec. 51.905(e)(4) which waived the requirement to retain
1-hour requirements for nonattainment NSR in SIPs.\5\ Also, EPA is
proposing to amend Sec. 51.905(a)(3), which details how areas
transition from 1-hour NAAQS to 8-hour NAAQS, and to remove the phrase
``subject to paragraph (e)(4) of this section'' because paragraph
(e)(4) was vacated.
---------------------------------------------------------------------------
\5\ In addition, that separate proposed rule addresses two other
aspects of the rule vacated by the Court in South Coast: (1) How EPA
will classify areas that it had placed under subpart 1 in the Phase
1 Rule, and (2) anti-backsliding requirements for contingency
measures that apply for failure to make progress toward or to attain
the 1-hour standard.
---------------------------------------------------------------------------
A. Applicability of 1-Hour NSR Requirements
In South Coast, the Court concluded that the 1-hour major NSR
requirements are controls, and that withdrawing them from the 8-hour
nonattainment NSR SIP ``would constitute impermissible backsliding.''
472 F.3d. 882, 900. The Court vacated the provision of the Phase 1 Rule
that allowed States, regardless of the 8-hour designation for an area,
to request that the SIP be revised to remove 1-hour major NSR
requirements upon revocation of the 1-hour standard.\6\ As noted above,
we have previously proposed to remove that vacated provision. 74 FR
2936 (January 16, 2009). In this action, we are proposing to add new
regulatory text to make it clear that any 8-hour nonattainment area
designated as 1-hour nonattainment as of the date of 1997 8-hour NAAQS
designation must continue to apply NSR requirements consistent with
that area's 1-hour classification.\7\ Such areas cannot remove 1-hour
major NSR requirements from their SIPs based solely on revocation of
the 1-hour standard. The implications for areas that are designated
attainment for the 1997 8-hour standard, or have been redesignated to
attainment for that standard, and that were designated nonattainment
for the 1-hour standard at the time of designation for the 1997 8-hour
standard are discussed in section III.B.1. of this preamble.
---------------------------------------------------------------------------
\6\ These same provisions also allowed States which had not yet
adopted such programs to not adopt and submit such SIPs. The Court
also vacated the regulation to the extent it waived the obligation
to submit such SIPs.
\7\ In most areas, the date of designation was June 15, 2004.
---------------------------------------------------------------------------
The areas for which anti-backsliding requirements would have
applied as of June 15, 2004, are listed in Table 1. The areas in Table
1 had a 1-hour NAAQS nonattainment classification with more stringent
NSR program requirements than the classification under the 1997 8-hour
standard on the date of designation under the 8-hour standard, June 15,
2004. Some areas potentially affected have been redesignated to
attainment for the 1997 ozone NAAQS since June 15, 2004, and would be
treated as described in section III.B.

* Indicates area has been redesignated to ``attainment'' as of July 2010 for the 1997 8-hour ozone standard.
Areas that have been redesignated to attainment are no longer required to implement nonattainment NSR, but
must at a minimum implement the PSD program.
[[Page 51964]]
B. Removal of 1-Hour NSR Requirements
1. Treatment of 8-Hour Attainment Areas
EPA does not interpret the South Coast decision as requiring that
1-hour nonattainment NSR be retained in areas designated attainment for
the 1997 8-hour standard. Accordingly, in this notice EPA is clarifying
that it will continue to follow the provisions of 40 CFR 51.905(a)(3)
with regard to removal of 1-hour NSR requirements in 1997 8-hour ozone
NAAQS attainment areas. EPA is not proposing to change its treatment of
such areas. As explained previously, 51.905(a)(3) allows 1997 8-hour
NAAQS attainment areas, that were designated nonattainment for the 1-
hour standard at the time of their attainment designation for the 8-
hour standard, to request that the 1-hour nonattainment NSR provisions
be removed from the SIP. (We note that EPA's practice since the
revocation of the 1-hour standard has also been to allow 1997 8-hour
ozone NAAQS nonattainment areas, that were designated nonattainment for
the 1-hour standard at the time of their 8-hour nonattainment
designation, to request that the 1-hour nonattainment NSR requirements
be removed from their SIPs upon redesignation of the area to attainment
of the 1997 8-hour NAAQS.) In lieu of nonattainment NSR, these areas,
with the exception of those located in the Ozone Transport Region
(OTR), are subject to prevention of significant deterioration (PSD)
program requirements based on their 8-hour attainment designation or
redesignation. For areas that are located in the OTR, ozone
nonattainment NSR requirements associated with the moderate
nonattainment classification apply regardless of an area's designation.
In the South Coast litigation, the petitioners' briefs
characterized the Phase 1 Rule as removing ``requirements to control
pollution from new and modified stationary sources in nonattainment
areas.'' Opening Brief of Environmental Petitioners and South Coast Air
Quality Management District at 17 (emphasis added); see also Brief for
the Commonwealth of Massachusetts et al. at 14. Thus, the issue before
the Court was whether EPA had acted unlawfully by ``permitting 8-hour
nonattainment areas to only meet weaker requirements under their 8-hour
classifications.'' Opening Brief of Environmental Petitioners and South
Coast Air Quality Management District at 20. The Court distinguished
the South Coast decision from the decision in Greenbaum v. EPA, 370
F.3d 527 (6th Cir. 2004) in part because ``Greenbaum involved a
different ultimate question, namely, whether NSR is required for
attainment areas.'' 472 F.3d. at 902. As the Court noted, ``NSR is a
permitting process that restricts major modifications and new
construction based on an area's air-quality classification * * *. As
relevant, NSR requires major facilities to include technology
consistent with the lowest achievable emissions rate (``LAER'') and to
offset any increased emissions with greater reductions elsewhere.'' 472
F.3d. at 900. The Court stated that ``EPA decided that 1-hour NSR
requirements are no longer required under the Act and that areas should
be constrained only by the NSR requirements for their eight-hour
classification * * *. This marked a change from its 2003 notice of
proposed rulemaking, in which EPA indicated that `the major source
applicability cut-offs and offset ratios continue to apply to the
extent that the area has a higher classification for the 1-hour
standard than for the 8-hour standard.' '' 472 F.3d. at 901. The Court
stated that the result of the change from the 2003 proposal to the
approach adopted in the final Phase 1 Rule was ``to subject fewer areas
to LAER and to offset requirements that themselves are weakened.''
Thus, the issue before the Court involved the substitution of one set
of nonattainment NSR requirements for another, and not the replacement
of nonattainment NSR with a PSD program in areas attaining the current
NAAQS.
EPA has determined that 1-hour nonattainment major NSR should not
apply to areas designated attainment for the 1997 8-hour standard,
regardless of the area's designation for the 1-hour standard at the
time of designation for the 8-hour standard. The interpretation that
NSR does not apply to areas designated attainment for a NAAQS and thus
is not needed in the SIP for such an area is consistent with Greenbaum
v. EPA, 370 F.3rd 527, at 536 (``It would make little sense for [NSR]
to be included in the post-attainment SIP, as the Clean Air Act * * *
explicitly states that attainment area SIPs must include a PSD
program.''). As the DC Circuit held in Alabama Power, 636 F.3d 323, at
365 (DC Cir. 1979), the applicability of PSD is geographically limited
by the language of CAA section 165(a), which states that unless
specified conditions are met, ``[n]o major emitting facility * * * may
be constructed in any area to which this part [Part C] applies''
(emphasis added). Thus, with respect to ozone, areas designated
attainment for the 1997 8-hour standard are subject to section 165(a)
but not to the section 172(c)(5) SIP requirement. For this reason, EPA
is not requiring that areas designated attainment for the 1997 8-hour
standard retain 1-hour NSR provisions. Instead, 8-hour attainment areas
may request that 1-hour nonattainment NSR provisions be removed from
their SIPs, with PSD taking the place of the nonattainment NSR program
for ozone. For the same reason, as set forth below, EPA is proposing to
revise the regulations to clarify that this treatment also applies to
areas that are redesignated to attainment for the 1997 8-hour standard.
2. Treatment of Areas Designated Nonattainment for Both 1-Hour and 8-
Hour Ozone NAAQS
Although the Court in South Coast determined that 1-hour
nonattainment NSR must be retained as an anti-backsliding measure in
1997 8-hour nonattainment areas that were designated nonattainment for
the 1-hour standard at the time of the 8-hour designations, the Court
did not specifically address how long such requirements must remain in
place. In our Phase 1 Rule, we linked removal of the 1-hour
requirements retained as ``applicable requirements'' to attainment of
the 8-hour NAAQS. The rule at Sec. 51.905(b) provides that an 8-hour
nonattainment area will remain subject to the 13 applicable
requirements listed in Sec. 51.900(f) until it attains the 8-hour
standard. Section 51.905(b) further provides that after an area attains
the 8-hour standard, the State may request that the 1-hour obligations
be shifted to contingency measures, but may not remove them completely
from the SIP. The preamble to the Phase 1 Rule clarified that, ``it is
appropriate to maintain these mandated controls to remain as part of
the implemented SIP until an area attains the 8-hour NAAQS and is
redesignated to attainment.'' (69 FR 23983).
In deciding how to adopt regulatory text consistent with the South
Coast decision, we do not believe it is appropriate to add the 1-hour
nonattainment NSR obligation to the list of applicable requirements in
Sec. 51.900(f) because we do not believe it should remain in the SIP
as a contingency measure after redesignation for the 8-hour standard.
Consistent with Greenbaum v. EPA, 370 F.3rd 527, 536, nonattainment
major NSR requirements are no longer a necessary SIP element once an
area is redesignated to attainment for a NAAQS. Upon redesignation to
attainment, the PSD program requirements would apply to
[[Page 51965]]
the area.\8\ Therefore, nonattainment major NSR requirements may be
removed from the SIP, and do not need to be retained as contingency
measures for a NAAQS.
---------------------------------------------------------------------------
\8\ The one exception to this is that all areas located in the
Ozone Transport Region, including those designated attainment, are
subject to the obligation to have a nonattainment NSR program.
---------------------------------------------------------------------------
In lieu of adding 1-hour major NSR to the Sec. 51.900(f) list of
applicable requirements, we are proposing to add a new Sec. 51.905(g)
and an analogous new Section VII in Appendix S. The new sections
clarify the obligation for any 1997 8-hour nonattainment area with a 1-
hour nonattainment designation as of the effective date of designation
for the 8-hour standard (June 15, 2004 for most areas) to continue to
apply 1-hour nonattainment NSR requirements consistent with the area's
1-hour classification, as listed in 40 CFR part 81 subpart C.
Although we are not proposing to add NSR to the list of applicable
requirements in 51.900(f), we are proposing that, as with those
requirements, 1-hour NSR requirements continue to be required SIP
elements until redesignation to attainment of the 1997 8-hour ozone
NAAQS.\9\ Under EPA's proposed revision set forth above, the 1-hour
major NSR requirements may be removed only after an area has attained
and been redesignated for the 1997 8-hour NAAQS. Under this approach,
the 1-hour NSR requirements would be treated in a manner similar to the
13 applicable requirements listed at Sec. 51.900(f), except that the
State would not be required to retain the 1-hour NSR requirements as
contingency measures. Instead, PSD would apply upon redesignation to
attainment for the 1997 8-hour standard, and 1-hour NSR requirements
could be removed entirely from the SIP.
---------------------------------------------------------------------------
\9\ We note that although the regulatory text provides that the
requirements of section 51.900(f) apply until an area ``attains''
the 8-hour ozone NAAQS, the accompanying preamble text clarifies
that these requirements apply until an area is redesignated as
attainment for the 1997 8-hour ozone NAAQS. 69 FR 23982-83.
---------------------------------------------------------------------------
As set forth in section III.B.2.b., we are also requesting comment
on a separate and additional basis--attainment of the 1-hour ozone
NAAQS (plus specified criteria)--for allowing States to remove 1-hour
NSR requirements. This opportunity to remove 1-hour NSR requirements
from the approved SIP would be in addition to the approach of allowing
States to remove 1-hour NSR upon redesignation to attainment for the 8-
hour NAAQS. Under this additional approach, where an area attains the
1-hour standard and meets certain other conditions (as determined by
EPA, in a rulemaking described below) but is still violating the 8-hour
standard, the State would be permitted, but not required, to remove the
1-hour nonattainment NSR requirements and apply the NSR requirements
associated with the 8-hour classification.
We note that neither EPA's proposal nor the separate, additional
approach to removal would have any effect on any source permit
conditions established during the time period the 1-hour major NSR
program applied. The NSR regulations do not provide a mechanism for
major NSR permit conditions established under the 1-hour standard to be
removed from a permit or modified when a SIP is later revised to remove
the 1-hour NSR thresholds and offset requirements. Replacement or
removal of NSR SIP provisions does not relieve sources of their
obligations under previously established permit conditions.
In addition, we note that this proposal to allow removal of the 1-
hour major NSR requirements after an area has attained and been
redesignated for the 1997 8-hour NAAQS could be affected by the
transition to a newer ozone standard.
a. Rationale for Removal of 1-Hour NSR Upon Redesignation to Attainment
of 8-Hour NAAQS
We are proposing to require areas to retain 1-hour major NSR
requirements until the area attains and is redesignated for the 1997
ozone 8-hour standard, regardless of when, if ever, the area attains
the 1-hour standard. The rationale for this approach, as set forth in
the June 2, 2003, Proposed Rule to Implement the 8-Hour Ozone National
Ambient Air Quality Standard (68 FR 32824), was that the 1997 8-hour
standard was the standard that EPA determined would protect public
health and the environment. We adopted this approach for the 13 listed
applicable requirements in Sec. 51.900(f), as discussed in the final
Phase 1 Rule (69 FR 23982-83). We believe this rationale also applies
to NSR. As stated in the Phase 1 Rule, Congress contemplated that
States implement certain requirements mandated under Subpart 2,
including specific NSR thresholds and offsets. Once an area
demonstrates that it has met and can maintain the more health
protective standard (the 1997 8-hour NAAQS), it would be appropriate to
remove 1-hour NSR requirements. In addition, adopting this approach for
NSR would result in similar treatment of NSR and the applicable
requirements in Sec. 51.900(f), the only difference being that States
would not need to include nonattainment NSR as a contingency measure.
We believe it is appropriate to treat NSR in a manner consistent with
the Sec. 51.900(f) applicable requirements. While we are taking
comment on the possibility of allowing States to remove NSR earlier
than the other requirements in some instances (see discussion below on
the additional basis), we do not plan to finalize that approach unless
we are persuaded that NSR is sufficiently different from the applicable
requirements identified in 51.900(f) to warrant different treatment.
EPA's proposed approach aligns with EPA's current practice
regarding areas that were initially designated as attainment for the
1997 8-hour NAAQS or have been redesignated to attainment for the 1997
8-hour ozone NAAQS. As noted above, EPA's current practice is to allow
areas to revise their SIPs to remove the 1-hour NSR requirements. This
approach harmonizes the treatment of areas initially designated as 8-
hour attainment and nonattainment areas that are redesignated to
attainment for the 8-hour standard. In lieu of nonattainment NSR, these
areas become subject to PSD programs based on their 8-hour attainment
designation or redesignation.
Additionally, we propose adding language to the CFR to clarify
applicability of section 181(b)(4)(B) for areas not attaining the
NAAQS. Notwithstanding revocation of earlier ozone NAAQS, States with
areas designated nonattainment for earlier ozone NAAQS, and classified
as severe or extreme for such standards as provided in 40 CFR part 81,
remain subject to the obligation to adopt programs under sections
181(b)(4) of the CAA. Section 181(b)(4)(B) specifies applicability of
NSR per requirements for extreme areas for specific instances of
failure to meet attainment schedules.
b. Supplemental Proposal: Removal of 1-Hour NSR Upon Attainment of 1-
Hour NAAQS and Determination of Eligibility To Remove NSR Requirements
(1) Attainment of 1-Hour NAAQS and Related Criteria
We are requesting comment on an additional approach that would
allow States to remove the 1-hour NSR requirements upon attainment of
the 1-hour ozone NAAQS and satisfaction of other criteria discussed
below in section ii. After notice and comment rulemaking, EPA would
make a determination that the area has attained the 1-hour standard and
met the additional requisite criteria. This would serve as a
``determination of eligibility to remove 1-hour NSR requirements.'' An
area that receives such a determination
[[Page 51966]]
would still be required to implement the nonattainment NSR requirements
associated with its 8-hour classification.
In our 2003 proposed rule, we took comment on the option of
allowing 1-hour obligations to be removed upon attaining the level of
the 1-hour standard. We noted that the rationale for allowing 1-hour
obligations to be removed upon attaining the level of the 1-hour
standard was that ``Congress intended an area to continue to implement
these obligations until it attained the 1-hour standard, at which time
the area would be able to discontinue implementation upon a showing of
continued maintenance'' (68 FR 32824, June 2, 2003). While we did not
finalize this option for the Sec. 51.900(f) applicable requirements,
we are requesting comment on whether we should adopt a variant of it
for NSR, and whether doing so would be consistent with the CAA and the
South Coast decision. In the final Phase 1 Rule, EPA decided that
attaining the 1-hour standard would not be a basis for allowing States
to remove from the SIP the 13 applicable requirements related to 1-hour
nonattainment identified at 51.900(f). The question is whether NSR
thresholds and offsets are more closely linked to a particular standard
than the 13 requirements listed in 51.900(f), and thus might be removed
following a determination of attainment of that standard, coupled with
other safeguards.
As noted above in the discussions of 8-hour attainment areas and
whether NSR requirements should become a contingency measure in a
maintenance plan attainment SIP, Congress clearly intended that
nonattainment major NSR was required only until the area was
redesignated to attainment. After that point, nonattainment major NSR
for that area would normally be superseded by the PSD program, whose
purpose is ``to protect public health and welfare from any actual or
potential adverse effect which in the Administrator's judgment may
reasonably be anticipated to occur * * * notwithstanding attainment and
maintenance.'' 42 U.S.C. 7470. In the case of areas that remain
nonattainment for the 8-hour standard after attaining the 1-hour
standard, however, the 8-hour major NSR requirements would apply rather
than PSD. Thus, the concern regarding the retention of nonattainment
major NSR requirements in an attainment SIP is not present here.
We are interested in comments addressing whether 1-hour NSR is
sufficiently different from the applicable requirements identified in
the Phase 1 Rule that we should allow States to remove it from their
SIPs prior to redesignation for the 1997 8-hour ozone standard.
(2). Defining ``Eligibility To Remove NSR Requirements'' Associated
With the Revoked 1-Hour Standard
In this section, we address which requirements, in addition to
attainment for the 1-hour ozone standard, the Supplemental Option would
impose on an area seeking to remove from its SIP 1-hour NSR
requirements prior to redesignation for the 1997 8-hour standard. In
the Phase 1 Rule, we stated that upon revocation of the 1-hour
standard, EPA was no longer obligated to determine whether an area had
attained that standard. However, under this supplemental approach, we
are proposing that a determination by EPA that an area has attained the
1-hour standard would be among the criteria for issuance of a
determination of eligibility to remove 1-hour NSR obligations. Prior to
the time that the 1-hour standard was revoked, a change in an ozone
nonattainment area's designation status required that the area satisfy
the criteria in section 107(d)(3)(E) of the CAA. These criteria
include: (i) A finding of attainment of the 1-hour standard based upon
the most recent three consecutive years of complete, quality assured
air quality data; (ii) the applicable implementation plan for the area
under section 110(k) has been fully approved by the Administrator;
(iii) the improvement in air quality leading to attainment of the 1-
hour NAAQS is due to permanent and enforceable reductions in emissions
resulting from implementation of the applicable implementation plan and
Federal air pollutant control regulations and other permanent and
enforceable reductions; (iv) the Administrator has fully approved a
maintenance plan for the area as meeting the requirements of section
175A; and (v) the State containing such area has met all requirements
applicable to the area under CAA section 110 and part D that pertain to
the 1-hour ozone standard.
Under this alternative, additional approach, we are taking comment
on which of the five criteria that would have applied for purposes of
redesignating an area for the 1-hour standard should apply for
declaring that an area has attained the 1-hour standard and is eligible
to remove 1-hour NSR requirements.
Under EPA's supplemental option, removal of the 1-hour requirements
would be permitted upon a determination of eligibility to remove NSR
requirements. To remove such programs, States would need to submit a
revision to their SIP, subject to the provisions of section 110(l)
which states that EPA may not approve a SIP revision ``if the revision
would interfere with any applicable requirement concerning attainment
and reasonable further progress (as defined in section 171), or any
other applicable requirement of the Act.''
In our Phase 1 Rule, which was vacated by the Court, we concluded
that a State's removal of 1-hour NSR requirements would not interfere
with 8-hour attainment or reasonable further progress. However, upon
additional consideration we now believe that we do not currently have
adequate data on the extent to which States may be relying on
particular major NSR thresholds and offset ratios for the growth
projections contained in their 8-hour attainment plans. Therefore, we
are not proposing an advance section 110(l) determination as part of
this action. We believe a case-by-case approach to section 110(l) under
the supplemental option detailed in this proposal will ensure that any
SIP changes upon a determination of eligibility to remove NSR
requirements for the 1-hour ozone NAAQS would not interfere with
reasonable further progress towards attainment of the 8-hour ozone
NAAQS.
IV. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is a significant regulatory action because it raises novel legal
or policy issues arising out of legal mandates. Accordingly, EPA
submitted this action to the Office of Management and Budget (OMB) for
review under EO 12866 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 sets forth EPA's proposed rule for addressing portions of
the partial vacatur of EPA's Phase 1 Rule for implementation of the
1997 8-Hour ozone NAAQS. However, OMB has previously approved the
information collection requirements contained in the existing Phase 1
Rule (April 30, 2004; 69 FR 23951) and the Phase 2 Rule (November 29,
2005; 70 FR 71612) under the provisions of the Paperwork Reduction Act,
44 U.S.C. 3501 et seq. and has assigned OMB Control Number 2060-0594.
The OMB control numbers
[[Page 51967]]
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 regulation subject
to notice and comment rulemaking requirements under the Administrative
Procedures Act or any other statute unless the Agency certifies 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 that is a
small industrial entity as defined in the U.S. Small Business
Administration (SBA) regulations at 13 CFR part 201; (2) a small
government 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 impact of this proposed rule on
small entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. This
proposed rule will not impose any requirements on small entities.
Rather, we are issuing this rule to give additional clarity to States
on the transition from 1-hour to 8-hour major NSR requirements. We
continue to be interested in the potential impacts of the proposed rule
on small entities and welcome comments on issues related to such
impacts.
D. Unfunded Mandates Reform Act
This action contains no Federal mandate under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (URMA), 2 U.S.C.
1531-1538 for State, local, and Tribal governments and the private
sector. The action imposes no enforceable duty on any State, local or
Tribal governments or the private sector. Therefore, this action is
subject to the requirements of section 202 and 205 of the UMRA.
This action is also not subject to the requirements of section 203
of UMRA because is contains no regulatory requirements that might
significantly or uniquely affect small governments. This action
proposes to revise the rule for implementing the 1997 8-hour ozone
NAAQS to address how nonattainment major NSR requirements associated
with the former 1-hour ozone NAAQS should apply under the anti-
backsliding provisions of the implementation rule. Also proposed is a
framework for allowing States to remove and/or no longer implement the
1-hour major NSR requirements when certain prescribed conditions are
met. This proposed rule responds to the ruling by the U.S. Court of
Appeals for the District of Columbia Circuit that the 1-hour major NSR
program, as it applies to areas that failed to attain the 1-hour
standard by the required date, is a required control to prevent
backsliding.
E. Executive Order 13132--Federalism
This proposed rule 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 sets forth EPA's
proposed rule for addressing portions of the partial vacatur of EPA's
Phase 1 Rule for implementation of the 1997 8-Hour ozone NAAQS. Thus,
Executive Order 13132 does not apply to this proposed rule.
In the spirit of Executive Order 13121 and consistent with EPA
policy to promote communications between EPA and State and local
governments, EPA specifically solicits comments on this proposed rule
from State and local officials.
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). It does not have
a substantial direct effect on one or more Indian Tribes, since no
Tribe has to develop a SIP under this proposal. Furthermore, this
proposed rule does not affect the relationship or distribution of power
and responsibilities between the Federal Government and Indian Tribes.
The CAA and the Tribal Air Rule establish the relationship of the
Federal Government and Tribes in developing plans to attain the NAAQS,
and these proposed revisions to the regulations do nothing to modify
that relationship. Thus, Executive Order 13175 does not apply to this
action.
EPA specifically solicits additional comment on the proposed rule
from Tribal officials.
G. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks
This action is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it is not economically significant as defined
in Executive Order 12866, and because the agency does not believe the
environmental health or safety risks addressed by this action present a
disproportional risk to children. This action sets forth EPA's proposed
rule for addressing portions of the partial vacatur of EPA's Phase 1
Rule for implementation of the 1997 8-Hour ozone NAAQS. The public is
invited to submit comments or identify peer-reviewed studies and data
that assess effects of this proposed action.
H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use
This proposed rule is not a ``significant energy action'' as
defined in Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'' (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. This action sets
forth EPA's proposed rule for addressing portions of the partial
vacatur of EPA's Phase 1 Rule for implementation of the 1997 8-Hour
ozone NAAQS.
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.
This proposed rule does not involve technical standards. Therefore,
EPA is not considering the use of any voluntary consensus standards.
[[Page 51968]]
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.
EPA has determined that this proposed rule 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. The proposed revisions implement a previously promulgated
health-based Federal standard (the 8-hour ozone NAAQS) that is designed
to protect all segments of the general population. As such, they do not
adversely affect the health or safety of minority or low income
populations and are designed to protect and enhance the health and
safety of these and other populations.
K. Determination Under Section 307(d)
Pursuant to section 307(d)(1)(V) of the CAA, the Administrator
determines that this action is subject to the provisions of section
307(d). Section 307(d)(1)(V) provides that the provisions of section
307(d) apply to ``such other actions as the Administrator may
determine.''
List of Subjects in 40 CFR Part 51
Environmental protection, Air pollution control, Intergovernmental
relations, Ozone, Transportation, Volatile organic compounds.
Dated: August 18, 2010.
Lisa P. Jackson,
Administrator.
For the reasons stated in the preamble, title 40, chapter I of the
Code of Federal Regulations is proposed to be amended as follows:
PART 51--REQUIREMENTS FOR PREPARATION, ADOPTION, AND SUBMITTAL OF
IMPLEMENTATION PLANS
1. The authority citation for part 51 continues to read as follows:
Authority: 23 U.S.C. 101; 42 U.S.C. 7401- 7671q.
2. Section 51.905 is amended by revising paragraph (a)(3)(i), and
by adding a new paragraph (g) to read as follows:
Sec. 51.905 How do areas transition from the 1-hour NAAQS to the 8-
hour NAAQS and what are the anti-backsliding provisions?
(a) * * *
(3) * * *
(i) Obligations in an approved SIP. For an area that is designated
8-hour NAAQS attainment/1-hour NAAQS nonattainment, the State may
request that obligations under the applicable requirements of Sec.
51.900(f) be shifted to contingency measures, consistent with sections
110(l) and 193 of the CAA, after revocation of the 1-hour NAAQS;
however, the State cannot remove the obligations from the SIP. For such
areas, the State may request that the nonattainment major NSR
provisions that applied based on the area's designation and
classification under the 1-hour NAAQS be removed from the SIP on or
after the date of revocation of the 1-hour NAAQS and need not be
shifted to contingency measures.
* * * * *
(g) What other requirements for the 1-hour standard apply? (1) The
requirements for nonattainment new source review that applied pursuant
to sections 172(c)(5), 173, and 182 of the Clean Air Act based on the
area's classification under the 1-hour NAAQS continue to be required
elements of an approvable implementation plan for any ozone
nonattainment area that was designated nonattainment for the 1-hour
NAAQS at the time of designation as ozone nonattainment for the 8-hour
NAAQS. Notwithstanding the revocation of the 1-hour NAAQS, the
designation and classification of the area for the 1-hour standard as
provided in 40 CFR Part 81 shall apply for determining the applicable
1-hour NSR obligation for an area. These requirements remain required
elements of the implementation plan until such time as the area is
redesignated to attainment for the 1997 8-hour attainment area for the
ozone NAAQS pursuant to Clean Air Act section 107(d)(3)(E).
(2) Notwithstanding revocation of the 1-hour ozone NAAQS, States
with areas designated nonattainment for the 1-hour ozone NAAQS and
classified as severe or extreme for that standard as provided in 40 CFR
Part 81 remain subject to the obligation to adopt programs under
sections 181(b)(4) of the CAA for the 1-hour ozone NAAQS.
3. Section 51.914 is revised to read as follows:
Sec. 51.914 What new source review requirements apply for ozone
nonattainment areas?
(a) The requirements for new source review for the 8-hour ozone
standard are located in Sec. 51.165.
(b) For areas designated nonattainment for the 1-hour ozone
standard as of the effective date of designation for the 8-hour
standard, values for applicability thresholds and offset requirements
as required under Sec. 51.165 shall be determined by the 1-hour
nonattainment classifications listed for those areas in 40 CFR Part 81,
