Proposed Rule To Implement the 1997 8-Hour Ozone National Ambient 
Air Quality Standard: Revision on Subpart 1 Area Reclassification and 
Anti-Backsliding Provisions Under Former 1-Hour Ozone Standard; 
Proposed Deletion of Obsolete 1-Hour Ozone Standard Provision

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to revise the rule for implementing the 1997 
8-hour ozone national ambient air quality standard (NAAQS) for several 
of the limited portions of the rule vacated by the U.S. Circuit Court 
of Appeals for the District of Columbia. The proposal addresses the 
classification system for the subset of initial 8-hour ozone 
nonattainment areas that the implementation rule originally covered 
under Clean Air Act (CAA or Act) title I, part D, subpart 1. The 
proposal also addresses how 1-hour ozone contingency measures that 
apply for failure to attain or make reasonable progress toward 
attainment of the 1-hour standard should apply under the anti-
backsliding provisions of the implementation rule. In addition, the 
proposal removes language relating to the vacated provisions of the 
rule that provided exemptions from the requirements of nonattainment 
new source review (NSR) and CAA section 185 penalty fees under the 1-
hour standard. The EPA plans to issue a separate proposed rule 
providing additional guidance as to how these two requirements (185 
fees and NSR) now apply.
    In addition, this proposal includes the deletion of an obsolete 
provision in the 1-hour ozone standard itself.

II. What Is the Background for This Proposal?

A. Litigation on EPA's 8-Hour Ozone NAAQS Implementation Rule (40 CFR 
Part 51, Sections 51.900 Through 51.918 (Collectively Subpart X))

    On April 30, 2004 (69 FR 23951), EPA published Phase 1 of a final 
rule that addressed the following key elements for implementing the 
1997 8-hour ozone NAAQS: Classifications for the 1997 8-hour NAAQS; 
revocation of the 1-hour NAAQS (i.e., when the 1-hour NAAQS will no 
longer apply); anti-backsliding principles for 1-hour ozone

[[Page 2938]]

requirements to ensure continued progress toward attainment of the 1997 
8-hour ozone NAAQS; attainment dates; and the timing of emissions 
reductions needed for attainment.
    Following publication of the April 30, 2004 final Phase 1 Rule, the 
Administrator received three petitions, pursuant to section 
307(b)(7)(B) of the CAA requesting reconsideration of a number of 
aspects of the final rule.\1\ In final rulemaking on one of these 
petitions, EPA further clarified the implementation rule in two 
respects: (a) 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.\2\ Additionally, EPA clarified that the 
requirement to have 1-hour contingency measures for failure to make 
progress or failure to attain would no longer apply once the 1-hour 
standard was revoked. On April 4, 2005 (70 FR 17018), we published a 
proposed rule to take comment on the issue of whether we should 
interpret the Act to require areas to retain major NSR requirements 
that apply to certain 1-hour ozone nonattainment areas in implementing 
the 1997 8-hour standard. We took final action on the NSR issues on 
June 30, 2005 (70 FR 39413; July 8, 2005), to interpret the CAA to not 
require NSR under the 1-hour standard once the 1-hour standard was 
revoked.
---------------------------------------------------------------------------

    \1\ Three petitions for reconsideration of the Phase 1 Rule were 
filed by: (1) Earthjustice on behalf of the American Lung 
Association, Environmental Defense, 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.
    \2\ 70 FR 30592 (May 26, 2005).
---------------------------------------------------------------------------

    Several parties challenged EPA's Phase 1 Rule and the two 
reconsideration rules, and on December 22, 2006, the Court upheld 
certain challenges and rejected others, but purported to vacate the 
Phase 1 Implementation Rule in its entirety. South Coast Air Quality 
Management District, et al., v. EPA, 472 F.3d 882 (D.C. Cir. 2006) 
reh'g denied 489 F.3d 1245 (clarifying that the vacatur was limited to 
the issues on which the court granted the petitions for review).
    The EPA requested rehearing and clarification of the ruling and on 
June 8, 2007, the Court clarified that it was vacating the rule only to 
the extent that it had upheld petitioners' challenges. Thus, the 
following provisions of the Phase 1 rule were vacated:
     The provisions that placed 8-hour ozone nonattainment 
areas under subpart 1, part D, title I of the CAA instead of subpart 2.
     The provisions that waived obligations under the revoked 
1-hour standard for NSR, section 185 penalty fees, and contingency 
measures for failure to attain or to make reasonable progress toward 
attainment of the 1-hour standard.\3\
---------------------------------------------------------------------------

    \3\ The Court's June clarification confirmed that the December 
2006 decision was not intended to establish a requirement that areas 
continue to demonstrate conformity for the 1-hour ozone standard for 
anti-backsliding purposes.
---------------------------------------------------------------------------

B. Obsolete Provision in 1-Hour Ozone Standard (40 CFR Part 50)

    When EPA promulgated the 8-hour ozone standard on July 18, 1997 (62 
FR 38856), EPA initially revised 40 CFR 50.9 to revoke the 1-hour ozone 
standard once EPA determined that an area had air quality meeting the 
1-hour standard. Subsequently, because the pending litigation over the 
8-hour NAAQS created uncertainty regarding the 8-hour NAAQS and our 
implementation strategy, we revised 40 CFR 50.9 to place two 
limitations on our authority to apply the revocation rule: (1) The 8-
hour NAAQS must no longer be subject to legal challenge, and (2) it 
must be fully enforceable.\4\ (65 FR 45182, July 20, 2000). These 
limitations were codified as Sec.  50.9(c). In the final Phase 1 Rule, 
we again revised Sec.  50.9, this time to revise Sec.  50.9(b) to 
provide for revocation of the 1-hour standard one year after 
designation of areas under the 1997 8-hour ozone standard. However, we 
neglected to remove paragraph (c) which was no longer necessary as the 
8-hour standard was no longer subject to legal challenge and the 
standard had been upheld and was enforceable. American Trucking Assoc.

challenges to the 8-hour ozone standard and upholding EPA's rule

    \4\ In addition, in June 2003, we stayed our authority to apply 
the revocation rule pending our reconsideration in this rulemaking 
of the basis for revocation. (68 FR 38160, June 26, 2003).
---------------------------------------------------------------------------

III. This Action

A. Reclassification of Subpart 1 8-Hour Ozone Nonattainment Areas

1. Current Rule
    In the Phase 1 implementation rule, EPA established which planning 
requirements of part D of title I of the Act would apply to areas for 
purposes of implementing the 8-hour ozone standard. 40 CFR 51.902. 
(``Which classification and nonattainment area planning provisions of 
the CAA shall apply to areas designated nonattainment for the 8-hour 
NAAQS?'') Paragraph (a) provided that areas with a 1-hour ozone design 
value equal to or greater than 0.121 parts per million (ppm) at the 
time of 8-hour NAAQS nonattainment designation (April 2004) would be 
classified in accordance with CAA title I, part D, section 181 of the 
CAA as interpreted in 40 CFR 51.903(a) for purposes of the 8-hour 
NAAQS, and would be subject to the requirements of CAA title I, part D, 
subpart 2 that apply for the area's classification. 40 CFR 51.903(a) 
set forth a translation into 8-hour design values of the CAA section 
181 classification table, which is written in terms of 1-hour ozone 
design values. The preamble to the Phase 1 Rule provides the rationale 
and procedure for that translation. (See 69 FR 23958 et seq.) Section 
181 in subpart 2 provides for specific classifications of each area by 
the magnitude of the ozone problem, providing shorter time periods for 
attainment for lower classifications and longer time periods for higher 
classifications. Higher classified areas also face additional specified 
control requirements than lower classified areas. A summary listing of 
the subpart 2 requirements by classification compared to subpart 1 
requirements appeared in the proposed 8-hour ozone implementation rule. 
(See 68 FR 32864, Appendix A; June 2, 2003.)
    Paragraph (b) of Sec.  51.902 provided that 1997 8-hour ozone 
nonattainment areas with a 1-hour design value less than 0.121 ppm at 
the time of 8-hour NAAQS nonattainment designation would be covered 
under section 172(a)(1) of the CAA and would be subject to the 
requirements of CAA title I, part D, subpart 1 and not those of subpart 
2.
    The EPA designated areas for the 1997 8-hour standard on April 30, 
2004 (69 FR 23858), and in accordance with section 181(a), the areas 
subject to subpart 2 under the Phase 1 Rule were classified by 
operation of law at that time. Of the 126 areas designated 
nonattainment, 84 were classified as under subpart 1, and the remaining 
42 as under subpart 2.\5\
---------------------------------------------------------------------------

    \5\ 13 of the 84 subpart 1 areas and one subpart 2 area were 
designated as ``Early Action Compact Areas'' with a deferred 
effective date for their nonattainment designation.

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

[[Page 2939]]

2. Effect of Court Ruling
    In its decisions on the Phase 1 rule, the Court vacated the 
provisions that subjected any 8-hour ozone nonattainment areas to 
coverage under subpart 1. As the basis for its decision, the Court 
first agreed that Congress mandated that certain areas be subject to 
subpart 2, but ruled that our use of 0.121 ppm 1-hour design value as a 
dividing line was incorrect, holding that the Supreme Court had 
required use of 0.09 ppm on the 8-hour scale as the level for 
determining which areas Congress mandated would be subject to subpart 
2.\6\ Furthermore, although recognizing that Congress did not mandate 
that areas with an 8-hour design value be subject to subpart 2, the 
Court rejected as unreasonable our rationale for placing certain areas 
in subpart 1 instead of subpart 2. The Court vacated the Phase 1 rule 
to the extent it placed certain areas solely under the implementation 
provisions of subpart 1. Thus, a rule revision is necessary to address 
which provisions of the Act--only subpart 1 or subpart 2 \7\--should 
apply to those areas that were placed solely under subpart 1 in the 
Phase 1 Rule.
---------------------------------------------------------------------------

    \6\ ``* * * the gap identified in Whitman affords EPA discretion 
only to the extent that an area is nonattaining but its air quality 
is not as dangerous as the level addressed by the 1990 Amendments, 
which now translates to 0.09 ppm on the 8 hour scale. Thus, the gap 
extends only to the extent that the standard was strengthened and 
not to the extent that the measurement technique merely changed * * 
* We therefore hold that the 2004 Rule violates the Act insofar as 
it subjects areas with 8-hour ozone in excess of 0.09 ppm to Subpart 
1. We further hold that EPA's interpretation of the Act in a manner 
to maximize its own discretion is unreasonable because the clear 
intent of Congress in enacting the 1990 Amendments was to the 
contrary.''
    \7\ We note that areas subject to subpart 2 are also subject to 
subpart 1 to the extent subpart 1 specifies requirements that are 
not superseded by more specific obligations under subpart 2.
---------------------------------------------------------------------------

3. Proposed Rule
    We are proposing that all areas designated nonattainment for the 
1997 8-hour ozone standard will be classified under and subject to the 
nonattainment planning requirements of subpart 2. We would modify the 
regulatory text to remove current Sec.  51.902(b) (which was vacated by 
the Court), which placed certain areas only under subpart 1. We 
considered the possibility of proposing to place areas with design 
values below 0.09 ppm 8-hour design value under subpart 1, but are not 
proposing this option in the interest of not further delaying 
implementation of the 8-hour ozone NAAQS that was established over 10 
years ago.\8\ However, we solicit comment on this part of this 
proposal.
---------------------------------------------------------------------------

    \8\ As the court made clear in its decision on rehearing, the 
CAA does not mandate coverage under subpart 2 of all areas 
designated nonattainment for an ozone NAAQS. As EPA moves forward to 
develop an implementation strategy for the new 2007 ozone NAAQS, we 
will consider whether subpart 1 alone might apply in some areas for 
purposes of implementing that NAAQS.
---------------------------------------------------------------------------

    Because these are the initial classifications for these areas for 
the 1997 ozone standard, the EPA further proposes to use the 8-hour 
ozone design values (from 2001-2003 air quality data) that were used to 
designate these areas nonattainment initially as the basis for 
classification and that the classification table in 40 CFR 51.903 
(established by the Phase 1 Rule) be used for the classification. CAA 
section 181(a) provides that ``at the time'' areas are designated for a 
NAAQS, they will be classified ``by operation of law'' based on the 
``design value'' of the areas and in accordance with table 1 of that 
section. Thus, this language specifies that the area will be classified 
based on the design value that existed for the area ``at the time'' of 
designation. Areas were designated nonattainment in 2004, based on 
design values derived from data from 2001-2003. We are soliciting 
comment on the approach of classifying these areas based on the same 
data that was used for designation.
    Also, since the classification under this proposal would be the 
initial one under the 1997 8-hour standard for these areas after court 
vacatur of the method EPA used to treat these areas under subpart 1 
only, EPA proposes that the provision of CAA section 181(a)(4) would 
apply to these areas, which would allow the Administrator in his 
discretion to adjust the classification--within 90 days after the 
initial classification--to a higher or lower classification ``* * * if 
the design value were 5 percent greater or 5 percent less than the 
level on which such classification was based.'' The EPA proposes to 
address requests for such classification adjustments for the newly-
classified areas that were originally covered under subpart 1 in a 
manner similar to the way described for the original round of subpart 2 
classifications.\9\ This process is described at 69 FR 23863 et seq. 
(April 30, 2004).
---------------------------------------------------------------------------

    \9\ Note, however, that if a State requests a reclassification 
from moderate to marginal and the attainment date for marginal areas 
has passed and the area is violating the standard, EPA would not 
grant the request for the reclassification.
---------------------------------------------------------------------------

    Of the original 84 subpart 1 areas designated in the April 30, 2004 
rulemaking, 13 areas successfully completed participation in the Early 
Action Compacts (EAC) program. As a result, these areas received 
deferred designations and classifications for as long as they continued 
to meet program requirements. These requirements were designed to 
ensure early reductions of ozone and progress toward attainment of the 
1997 NAAQS. At the completion of the program, these areas were 
designated attainment for the 8-hour ozone NAAQS effective April 15, 
2008.\10\
---------------------------------------------------------------------------

    \10\ One area (Denver, CO) that was originally part of the EAC 
program did not successfully complete all milestones and was 
subsequently designated nonattainment under subpart 1. Thus, this 
area would be treated the same as all areas classified under subpart 
1 under the original provisions of the Phase 1 Rule.
---------------------------------------------------------------------------

    Despite the proposal to implement the 1997 8-hour standard by 
classifying nonattainment areas under title I, part D, subpart 2 at 
this time, EPA reserves the right to propose to cover future ozone 
nonattainment areas under title I, part D, subpart 1, in accordance 
with the constraints outlined in the Court's rulings. The EPA may in 
the future examine the appropriate role for subpart 1 in classifying 
nonattainment areas and in flexible, efficient, enforceable 
implementation of an ozone NAAQS.
    Note that CAA section 182(h) (``Rural Transport Areas'') would be 
available for any nonattainment area that qualifies as a rural 
transport area under that section. A Rural Transport Area would have to 
only meet requirements of a marginal area.
4. Consequences of Proposed Rule
    Areas originally covered under subpart 1 that have already been 
redesignated to attainment will not be affected by this rule, including 
the 13 EAC areas noted above.\11\ Appendix A provides a listing of the 
former subpart 1 areas that are still designated nonattainment and that 
would be classified under subpart 2 under this proposed rule and 
provides the subpart 2 classification for the area based on the air 
quality data initially used to designate the area in the 2004 
designation rule. All of these areas would be classified as either 
marginal or moderate.\12\ The classification table of 40 CFR 51.903 
provides an outside attainment date based on a number of years after 
the effective date of the

[[Page 2940]]

nonattainment designation (3 years for marginal and 6 years for 
moderate). For all areas other than Denver, the effective date of 
designation for the 8-hour standard was June 15, 2004. Thus, marginal 
nonattainment areas would have a maximum statutory attainment date of 
June 15, 2007 and moderate areas a maximum date of June 15, 2010. Since 
the marginal area attainment date has passed, EPA proposes that any 
area that would be classified under the proposal as marginal, and that 
did not attain by June 15, 2007, or that does not meet the criteria for 
an attainment date extension under CAA section 181(a)(5)(B) and 40 CFR 
51.907, would be reclassified immediately as moderate under this rule.
---------------------------------------------------------------------------

    \11\ See, e.g., 73 FR 11558 (col. 2) (March 4, 2008), together 
with e.g., 73 FR 1166 (col 3) (January 8, 2008).
    \12\ Note that Essex Co (the top of Whiteface Mtn), NY, and Door 
County, WI would be eligible for consideration under CAA section 
182(h) as a Rural Transport Area. This is based on the 1999 
definition of Metropolitan Statistical Areas; neither of the above 
two areas is in or adjacent to an MSA as defined by the Office of 
Management and Budget (OMB) in 1999 (June 30, 1999; 64 FR 35548).
---------------------------------------------------------------------------

    Areas classified marginal or moderate would be required to meet the 
marginal or moderate area requirements of CAA section 182(a) and/or 
(b). Moderate area requirements include the requirements for the 
marginal classification. Briefly, these requirements are depicted in 
Table 1:

------------------------------------------------------------------------
\a\ Note that subpart 1 requirements also apply to subpart 2 areas to
  the extent that the CAA does not provide an exemption (e.g., 182(a)
  (last paragraph, which exempts marginal areas from the requirement to
  submit an attainment demonstration)) or such requirements are not
  superseded by more specific obligations under subpart 2 (e.g., where
  subpart 2 specifies specific increments of progress for moderate and
  above areas in place of the more general requirement for ``reasonable
  further progress'' under subpart 1). Subpart 1 requirements that are
  also applicable to subpart 2 areas (but that are not addressed in
  subpart 2) include reasonably available control measures (RACM)
  requirement and transportation and general conformity requirements.

    With respect to transportation conformity requirements, current 
transportation plan and transportation improvement program conformity 
determinations for the 1997 8-hour ozone standard will remain valid, 
and are not impacted by this action. Areas that would be reclassified 
under subpart 2 are already satisfying the applicable CAA section 
176(c) conformity requirements for the 1997 8-hour ozone standard. In 
addition, no new conformity deadline would be triggered in the subject 
areas after their classification under subpart 2. Nonattainment areas 
that are classified as marginal or moderate under Subpart 2 would 
continue to make future conformity determinations according to the 
applicable requirements of 40 CFR 93.109(d) and (e). EPA notes that any 
new moderate areas that continue to be required to use the interim 
emissions tests will be required to meet additional test requirements 
that do not apply to marginal areas (40 CFR 93.119(b)(1)).
    The Phase 1 Rule provided that states must submit the major SIP 
elements for the subpart 1 areas no later than June 15, 2007. For areas 
classified as moderate, EPA also provided a submission date of June 15, 
2007 for most requirements, but required states to submit the 
reasonably available control technology requirement (RACT) SIP by 
September 15, 2006. The EPA proposes to require states to submit all 
required SIP elements for the areas' marginal or moderate 
classification one year after the effective date of a final rule 
classifying the areas. The EPA believes this is an appropriate and 
reasonable amount of time given the attainment dates that will apply to 
these areas and the fact that the areas should have made significant 
progress toward meeting these requirements based on the obligations 
that applied before the

[[Page 2941]]

subpart 1 classification provision of the Phase 1 rule was vacated. As 
subpart 1 areas, these areas should have been well along the path to 
developing SIPs at the time the Court issued its decision in December 
2006. We believe states have already had ample opportunity to complete 
the technical work to support development of these major SIP elements 
prior to now. Also, EPA has encouraged states to continue planning for 
clean air in the prior subpart 1 areas.\13\ Therefore, EPA believes one 
year from the date of final rule should be sufficient time for states 
to submit these SIPs. However, EPA solicits comment on this aspect of 
the proposal.

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

B. Anti-Backsliding Under 1-Hour Ozone Standard--In General (Also 
Discussing NSR and Section 185 Penalty Fees)

    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). These provisions, as promulgated, retained 
most of the 1-hour ozone requirements as ``applicable requirements'' 
(defined in 40 CFR 51.900(f)). The requirements that are retained are 
those that applied in an area based on the area's 1-hour ozone 
designation and classification as of the effective date of its 8-hour 
designation (for most areas, June 15, 2004).
    Section 51.905(b) provides that a state remains subject to the 
listed 1-hour standard obligations until the area attains the 8-hour 
NAAQS. Furthermore, Sec.  51.905(b) provides that such obligations 
cannot be removed from a SIP, even if the area is redesignated to 
attainment for the 8-hour NAAQS, but must remain in the SIP as 
applicable requirements or as contingency measures, as appropriate.
    Section 51.905(e), as promulgated in 2004, indicated that certain 
1-hour standard requirements are not part of the list of anti-
backsliding requirements. These include 1-hour NSR, section 185 penalty 
fees, and 1-hour contingency measures for failure to attain or make 
reasonable progress toward attainment of the 1-hour NAAQS.\14\ The 
Court vacated these exemption provisions, and accordingly EPA is 
proposing to delete these exemptions from the rule. Thus, this proposal 
would remove language relating to the vacated provisions of the rule 
that provided exemptions from the requirements of nonattainment NSR and 
CAA section 185 penalty fees under the 1-hour standard in addition to 
the provision for contingency measures. The EPA plans to issue a 
separate proposed rule providing further guidance on how the section 
185 fee provisions and the 1-hour NSR requirements apply as a result of 
the Court's vacatur.\15\
---------------------------------------------------------------------------

    \14\ Note that if the area is nonattainment for the 1997 8-hour 
standard, it is subject to nonattainment NSR, contingency measures 
and (if severe or extreme) the section 185 penalty fee provision for 
that 1997 NAAQS.
    \15\ As noted above in a previous footnote, the Court's June 
2007 clarification confirms that the December 2006 decision was not 
intended to establish a requirement that areas continue to 
demonstrate conformity under the 1-hour ozone standard for anti-
backsliding purposes. Therefore, no revisions are necessary to 40 
CFR 51.905(e)(3) of the Phase 1 implementation rule. Section 40 CFR 
51.905(e)(3) establishes that conformity determinations for the 1-
hour standard are not required beginning 1 year after the effective 
date of the revocation of the 1-hour standard and any state 
conformity provisions in an applicable SIP that require 1-hour ozone 
conformity determinations are no longer federally enforceable. This 
provision does not require revision in light of the Court's decision 
and clarification, because the Court did not require conformity 
determinations for the 1-hour standard, and existing regulations 
already implement the Court's holding that 8-hour ozone 
nonattainment and maintenance areas must use 1-hour ozone budgets to 
determine conformity to the 1997 8-hour standard until such time as 
8-hour ozone budgets are approved or found adequate for the area. 
Therefore, current transportation conformity-related regulations set 
forth in 40 CFR part 93 and 40 CFR 51.905(e)(3), and the general 
conformity regulations in 40 CFR part 93 are consistent with the 
Court's decision and clarification on the Phase 1 8-hour ozone 
implementation rule and do not require revision.
---------------------------------------------------------------------------

    In the following section, in response to the Court vacatur, EPA 
proposes the manner in which the 1-hour NAAQS contingency measure 
requirement applies as an anti-backsliding requirement.

C. Contingency Measures

1. Phase 1 Rule
    The Phase 1 Rule did not address anti-backsliding provisions 
related to sections 172(c)(9) and 182(c)(9) of the CAA, which require 
nonattainment area SIPs to contain contingency measures that would be 
implemented if an areas fails to attain or fails to make RFP toward 
attainment of the 1-hour NAAQS. In the Reconsideration Rule published 
on May 26, 2005 (70 FR 30592), we determined that these 1-hour 
contingency measures would no longer be considered required SIP 
measures once the 1-hour standard was revoked. This meant that after 
the 1-hour standard was revoked, areas that had not submitted 1-hour 
attainment demonstrations or a specific 1-hour RFP SIP would no longer 
be required to submit contingency measures in conjunction with those 
SIPs. Also, the reconsideration rule stated that areas with approved 
section 172 and 182 contingency measures in the adopted SIP could 
submit a revision to remove them from their SIP when the 1-hour 
standard was revoked.
2. Effect of Court Ruling
    The Court concluded that EPA improperly waived the CAA requirements 
for contingency measures that would apply based on the failure of an 
area to meet a 1-hour RFP milestone or 1-hour attainment date. The 
Court vacated the provision of the Phase 1 Rule that waived this 
requirement for areas once the 1-hour standard was revoked. 
Consequently, areas remain subject to the obligation to have 
contingency measures for failure to attain the 1-hour NAAQS or make RFP 
toward attainment of the 1-hour NAAQS and cannot remove section 172 or 
182 contingency measures from their SIPs based on revocation of the 1-
hour standard.
3. Proposed Rule
    The EPA is proposing that states be required to retain contingency 
measures in their SIPs that would apply based on a failure to meet a 1-
hour RFP milestone or upon a failure to attain the 1-hour standard by 
the area's attainment date. Consistent with the Court's vacatur of 
Sec.  51.905(e)(2)(iii), which waived this requirement once the 1-hour 
standard was revoked, EPA proposes to remove this provision from the 
regulations. Furthermore, consistent with EPA's proposal to retain 
these 1-hour contingency measure requirements as anti-backsliding 
measures, we also propose to list contingency measures under sections 
172(c)(9) and 182(c)(9) of the CAA as applicable requirements under 
Sec.  51.900(f).
    In situations where an area attains the 1-hour NAAQS by its 
applicable attainment date, the area is not subject to the requirement 
to implement contingency measures for failure to attain the standard by 
its attainment date. As a result, any area that meets or has met its 
attainment deadline, even if the area subsequently lapses into 
nonattainment, would not be required to implement the contingency 
measures for failure to attain the standard by its attainment date for 
purposes of anti-backsliding.
    In situations where a 1-hour ozone nonattainment area is in 
attainment based on current air quality (e.g., after the area's 
attainment date), EPA can

[[Page 2942]]

propose to make a finding of attainment.\16\ This finding would be 
pursuant to the interpretation set forth in the May 10, 1995 memorandum 
from John S. Seitz, Director, Office of Air Quality Planning and 
Standards, entitled ``Reasonable Further Progress, Attainment 
Demonstration, and Related Requirements for Ozone Nonattainment Areas 
Meeting the Ozone Ambient Air Quality Standard'' (Clean Data Policy). 
Under this policy, if EPA determines through rulemaking that the area 
is meeting the 1-hour ozone standard, the requirements for the state to 
submit an attainment demonstration and related components such as 
reasonably available control measures (RACM), RFP demonstration, 
contingency measures for failure to attain or make reasonable further 
progress and the section 185 fees program are suspended as long as the 
area continues to attain the 1-hour ozone NAAQS. If the area 
subsequently violates the ozone NAAQS, EPA would initiate notice-and-
comment rulemaking to withdraw the determination of attainment, which 
would result in reinstatement of the requirement for the state to 
submit such plans.
---------------------------------------------------------------------------

    \16\ This applies even if the area did not attain by its 
attainment date; however, the CAA requires EPA in these cases to 
make a finding of failure to attain by the attainment date and 
either reclassify the area or apply other requirements (such as 
section 185) as specified for the area's classification.
---------------------------------------------------------------------------

    The Tenth, Seventh and Ninth Circuits have upheld EPA rulemakings 
applying the Clean Data Policy. See Sierra Club v. EPA, 99 F. 3d 1551 
(10th Cir. 1996); Sierra Club v. EPA. 375 F.3d 537 (7th Cir. 2004) and 
Our Children's Earth Foundation v. EPA, No. 04-73032 (9th Cir. June 28, 
2005) memorandum opinion.\17\ See also the discussion and rulemakings 
cited in EPA's Phase 2, 8-Hour Ozone Implementation Rulemaking, 70 FR 
71644-71646 (November 29, 2005), which codified the policy for the 8-
hour NAAQS.
---------------------------------------------------------------------------

    \17\ The Clean Data Policy, as it is embodied in 40 CFR. 51.918, 
is being challenged in the context of the 8-hour ozone standard in 
the Phase 2 Rule ozone litigation pending in the DC Circuit, NRDC v. 
EPA, No. 06-1045 (DC Cir.).
---------------------------------------------------------------------------

    Thus if EPA makes a determination of attainment under the Clean 
Data Policy, EPA would find that the requirement to submit section 172 
and 182 contingency measures under the 1-hour anti-backsliding 
provisions (40 CFR 51.905) would be suspended for so long as the area 
continues to attain the 1-hour standard.
    Under 40 CFR 51.905(b), states remain subject to the obligations 
under Sec.  51.905(a)(1)(i) and (a)(2) until the area attains the 8-
hour NAAQS for purposes of anti-backsliding. After the area attains the 
8-hour NAAQS, states may request that these obligations be shifted to 
contingency measures, consistent with sections 110(l) and 193 of the 
CAA; however, the state cannot remove the obligations from the SIP.

D. Deletion of Obsolete 1-Hour Ozone Standard Provision

    For the reasons stated above in the background section concerning 
the obsolete nature of 40 CFR 50.9(c), we are proposing to delete that 
paragraph. This will have no effect on the status of the 1-hour ozone 
standard,\18\ or on the anti-backsliding provisions which set forth how 
areas must meet 1-hour requirements that applied to the area at the 
time the area was designated for the 8-hour standard.
---------------------------------------------------------------------------

    \18\ The 1-hour standard was revoked for most areas on June 15, 
2005, the date one-year after the effective date of designation. For 
the 13 EAC areas designated attainment with an effective date of 
April 15, 2008, the 1-hour standard will be revoked April 15, 2009, 
and for the Denver EAC area, which was designated nonattainment 
effective November 20, 2007, the 1-hour standard will be revoked 
November 20, 2008.

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, the Office of Management and Budget 
(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) regulations and 
has been assigned OMB Control Number 2060-0594. The OMB control numbers 
for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an Agency 
to prepare a regulatory flexibility analysis of any 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 these proposed regulations 
revisions 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) size standards. (See 13 CFR 121.); (2) A 
governmental jurisdiction that is a government of a city, county, town, 
school district or special district with a population of less than 
50,000; and (3) A small organization that is any not-for-profit 
enterprise which is independently owned and operated and is not 
dominant in its field.
    After considering the economic impact of these proposed revisions 
to the regulations on small entities, I certify that this action will 
not have a significant economic impact on a substantial number of small 
entities. This proposal will not impose any requirements on small 
entities.
    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 (UMRA), 2 U.S.C. 
1531-1538 for State, local, or tribal governments or the private 
sector. The action imposes no enforceable duty on any State, local or 
tribal governments or the private sector. Therefore, this action is not 
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 it contains no regulatory requirements that might 
significantly or uniquely affect small governments. The EPA has 
determined that these proposed regulation revisions contain no 
regulatory requirements that may significantly or uniquely affect small 
governments, including tribal governments because these regulations 
affect Federal agencies only.

E. Executive Order 13132--Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by state

[[Page 2943]]

and local officials in the development of regulatory policies that have 
Federalism implications.'' Policies that have ``Federalism 
implications'' are defined in the Executive Order to include 
regulations that have ``substantial direct effects on the states, on 
the relationship between the national government and the states, or on 
the distribution of power and responsibilities among the various levels 
of government.''
    This action does not have Federalism implications. It will not have 
substantial direct effects on the states, on the relationship between 
the national 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 proposed rule, if made final, 
would restore provisions that existed under the 1-hour ozone standard 
and that would have continued under the 1-hour standard had not EPA 
issued a revised ozone standard. Those provisions were revoked when EPA 
revoked the 1-hour standard itself. Although a court upheld EPA's right 
to revoke the 1-hour standard, the court ruled that EPA erroneously 
revoked several 1-hour NAAQS provisions and vacated those portion of 
EPA's rule. Thus, the court's own ruling restored the former 1-hour 
NAAQS provisions. This proposed rule merely proposes a corrective 
regulatory mechanism for restoring the 1-hour contingency measure 
provision that the court had already restored. Thus, Executive Order 
13132 does not apply to these proposed regulation revisions.
    In the spirit of Executive Order 13121 and consistent with EPA 
policy to promote communications between EPA and state and local 
governments, EPA is soliciting comments on this proposal 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. They do not have a substantial direct effect on 
one or more Indian Tribes, since no Tribe has to develop a SIP under 
these proposed regulatory revisions. Furthermore, these proposed 
regulation revisions do 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 revisions to the regulations do nothing to modify that 
relationship. Thus, Executive Order 13175 does not apply.
    EPA specifically solicits additional comment on the proposed 
revisions to the regulations from Tribal officials.

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

    EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying 
only to those regulatory actions that concern health or safety risks, 
such that the analysis required under section 5-501 of the EO has the 
potential to influence the regulation. This action is not subject to EO 
13045 because these proposed rule revisions address whether a SIP will 
adequately attain and maintain the NAAQS and meet the obligations of 
the CAA. The NAAQS are promulgated to protect the health and welfare of 
sensitive population, including children. However, EPA solicits 
comments on whether the proposed action would result in an adverse 
environmental effect that would have a disproportionate effect on 
children.

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

    This action is not subject to Executive Order 13211 (66 FR 28355 
(May 22, 2001)), because it is not a significant regulatory action 
under Executive Order 12866.

I. National Technology Transfer 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 rulemaking does not involve technical standards. 
Therefore, EPA is not considering the use of any voluntary consensus 
standards.

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

    Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes 
Federal executive policy on environmental justice. Its main provision 
directs Federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    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 to the regulations would, if 
promulgated revise procedures for states to follow in developing SIPs 
to attain the NAAQS, which are designed to protect all segments of the 
general populations. 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 sections 307(d)(1)(E) and 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.''

Appendix A to Preamble. Application of the Proposed Classification 
Scheme

    This appendix lists the proposed new subpart 2 classifications for 
the areas that were originally covered under subpart 1 in the phase 1 
rule (April 30, 2004) and that are currently still designated 
nonattainment. The geographic boundaries of these nonattainment areas 
are provided in 40 CFR Part 81, Subpart C.
