Rescinding Findings That the 1-Hour Ozone Standard No Longer
Applies in Certain Areas

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: Today, EPA is rescinding its prior findings that the 1-hour
ozone national ambient air quality standard (NAAQS) and the
accompanying designations and classifications no longer apply in
certain areas. As part of a transition to a new, more protective 8-hour
ozone standard (promulgated in July 1997), in 1998 and 1999, EPA took
final action determining that the 1-hour standard would no longer apply
in almost 3,000 counties. Now, however, the public health protection
that would be afforded by the 8-hour ozone standard is being delayed
because continued litigation regarding the 8-hour ozone standard has
created uncertainty regarding when and whether EPA may be able to fully
implement that standard. It is important to have a fully enforceable
Federal ozone standard to help protect people from the respiratory and
other harmful effects of ozone pollution. Under this final rule, the
designations and classifications that previously applied in such areas
with respect to the 1-hour standard would also be reinstated. This rule
will become effective in 90 days for most areas, and will become
applicable in 180 days for areas with clean air quality data that had a
nonattainment designation when the 1-hour standard was revoked.
Furthermore, today EPA is taking final action to amend 40 CFR 50.9(b)
to provide by rule that the 1-hour ozone standard will continue to
apply to all areas notwithstanding promulgation of the 8-hour ozone
standard; and that after the 8-hour standard has become fully
enforceable under part D of title I of the Clean Air Act (CAA) and is
no longer subject to further legal challenge, the 1-hour standard set
forth in section 50.9(a) will no longer apply to an area once EPA
determines that the area has air quality meeting the 1-hour standard.

DATES: Effective Date: This rule is effective on October 18, 2000.
Applicability Dates: This rule applies on October 18, 2000 for all
areas where EPA had revoked the 1-hour ozone standard except for those
nonattainment areas with clean data listed in section III. F., Table 1
of the preamble, and applies on January 16, 2001 for such areas listed
in Table 1 of the preamble.

I. Background

The EPA promulgated a revised 8-hour ozone standard in July 1997
\1\ (62 FR 38856, July 18, 1997). At that time, EPA also promulgated 40
CFR 50.9(b), governing when the previous health-based ozone standard--
the 1-hour standard--would no longer apply to areas. Several parties
challenged EPA's revised ozone standard and EPA's revised particulate
matter standard, which was promulgated on the same day. American
Trucking Assoc. v. EPA, (D.C. Cir., Nos. 97-1440 and 97-1441) (ATA v.
EPA).
---------------------------------------------------------------------------

\1\ For both the 1-hour and 8-hour ozone standards, EPA has
promulgated secondary standards that are identical to the primary
standard. Because the primary and secondary standards are identical,
EPA refers to the 1-hour and 8-hour standards in the singular.
However, both EPA's initial rule determining that the 1-hour
standard no longer applied and this rule reinstating the
applicability of that standard apply for purposes of both the
primary and secondary 1-hour ozone standards. Similarly, EPA's
references to the 8-hour standard encompass both the primary and
secondary 8-hour standards.

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

[[Page 45183]]

On June 5, 1998 (63 FR 31014), July 22, 1998 (63 FR 39432), and
June 9, 1999 (64 FR 30911), in accordance with 40 CFR 50.9(b), we
issued final rules for many areas that were attaining the 1-hour
standard, finding that the 1-hour ozone standard no longer applied to
these areas. \2\ At that time, we amended the Code of Federal
Regulations (CFR) to remove the designations and classifications that
had applied to those areas for the 1-hour standard under sections 107,
172 and 181 of the CAA. \3\
---------------------------------------------------------------------------

\2\ Two of these final actions were challenged and these cases
are currently pending. Environmental Defense Fund v. EPA, (D.C.
Cir., No. 98-1363) (challenge to June 1998 final rule); Appalachian
Mountain Club v. EPA, (1st Cir., No. 99-1880) (challenge to June
1999 rule).
\3\ These rules are commonly referred to as the ``revocation''
rules. Technically, however EPA did not revoke the 1-hour standard
through these rulemakings. The 1-hour standard remains an effective
regulatory standard under EPA's regulations. 40 CFR 50.9(a).
---------------------------------------------------------------------------

On May 14, 1999, the Court of Appeals for the District of Columbia
Circuit (D.C. Circuit) issued an opinion in the cases challenging EPA's
revised ozone and particulate matter standards. ATA v. EPA, 175 F.3d
1027 (D.C. Cir., 1999). The court questioned the constitutionality of
the CAA authority to review and revise NAAQS, as applied in EPA's
revision to the ozone and particulate matter NAAQS. The Court stopped
short of finding the statutory grant of authority unconstitutional,
instead providing EPA with an opportunity to articulate a determinate
principle for revising the ozone and particulate matter NAAQS under the
statute. 175 F.3d at 1034-40. The court also addressed EPA's authority
to classify areas and to set attainment dates for a revised ozone
standard. 175 F.3d at 1034-40. Based on language in sections 172(a) and
181(a) of the CAA, the court concluded that EPA could only classify and
set attainment dates for areas for purposes of any ozone NAAQS under
the provisions of section 181(a) of the CAA, and that EPA could not
enforce an ozone NAAQS more quickly than contemplated under the
provisions triggered by classifications under section 181(a) nor could
EPA enforce an ozone standard, such as the 8-hour standard, that was
more stringent than the 1-hour standard. \4\ 175 F.3d at 1049-50. The
court also held that EPA must consider the beneficial effects of
tropospheric ozone in protecting against the harmful effects of
ultraviolet rays (UV-B). 175 F.3d at 1051-53. The court remanded, but
did not vacate, the 8-hour standard on the basis that it would not
``engender costly compliance activity'' in light of the court's
decision ``that it cannot be enforced by virtue of CAA Sec. 181(a).''
175 F.3d at 1057. The EPA filed a petition for rehearing with respect
to these three aspects of the court's decision. \5\
---------------------------------------------------------------------------

\4\ Sections 172(a) and 181(a) provide EPA with authority to
classify areas that are designated nonattainment and to set
attainment dates for those areas. Section 172(a) applies generally
to any new or revised NAAQS, while section 181(a) is specific to
certain ozone nonattainment areas.
\5\ The court decided other issues raised by the petitioners.
These issues were not raised on rehearing and are not relevant here.
---------------------------------------------------------------------------

On October 25, 1999, EPA published the preamble to the proposed
rule, ``Rescinding Findings That the 1-Hour Ozone Standard No Longer
Applies in Certain Areas,'' (64 FR 57424), noting that the proposed
regulatory language for part 81 would be published shortly. On November
5, 1999, EPA published the proposed regulatory language for part 81 (64
FR 60477). As proposed, the 1-hour ozone standard would be reinstated
in areas where it had previously been revoked and the associated
designations and classifications that previously applied in such areas
with respect to the 1-hour NAAQS also would be reinstated. In today's
final rule, EPA is taking final action to reinstate the area
designations and classifications that applied prior to revocation.
Throughout this final rule all references to reinstating designations
refer to reinstating both designations and classifications as well. In
addition, EPA proposed to amend 40 CFR 50.9(b) to provide by rule that
the 1-hour ozone standard would continue to apply in all areas
notwithstanding promulgation of the 8-hour standard, and that after the
8-hour standard has become fully enforceable under part D of title I of
the CAA and subject to no further legal challenge, the 1-hour standard
set forth in section 50.9(a) would no longer apply to an area once EPA
determines that the area has air quality meeting the 1-hour standard.
On October 29, 1999, the D.C. Circuit issued an opinion addressing
EPA's petition for rehearing. ATA v. EPA, 195 F.3d 4 (D.C. Cir. 1999).
The three-judge panel that decided the case granted rehearing on
limited issues regarding EPA's ability to implement a revised ozone
standard. Both the panel and the full court denied all other aspects of
EPA's petition for rehearing.\6\ With respect to EPA's authority to
implement a revised 8-hour standard, the court modified its initial
decision to provide that EPA may enforce a revised ozone NAAQS only in
conformity with the control requirements triggered by a classification
under section 181(a)--i.e., the provisions in subpart 2 of part D of
title I of the CAA. 195 F.3d at 8. Judge Tatel filed a separate
opinion, holding that the court should have deferred to EPA's
reasonable interpretation of the implementation scheme for the revised
NAAQS, but concurring in the majority's decision because it ``leaves
open the possibility that EPA can enforce the new ozone NAAQS without
conflicting with subpart 2's classifications and attainment dates.''
195 F.3d at 11.
---------------------------------------------------------------------------

\6\ The full court voted 5-4 in favor of rehearing with two
judges not participating. Since a majority vote of the active
members of the court is needed to grant rehearing, the request for
rehearing was denied.
---------------------------------------------------------------------------

At the request of commenters, on December 8, 1999, EPA published a
notice in the Federal Register (64 FR 68659) to reopen the comment
period for the proposed rulemaking from December 1, 1999 until January
3, 2000, thus affording the public a total of 60 days to comment on the
proposed reinstatement action.
On January 27, 2000, EPA filed a petition with the Supreme Court,
seeking review of the court of appeals decision regarding the
constitutionality of the provisions of the CAA for setting NAAQS and
the court's decision regarding implementation of a revised ozone NAAQS.
Other parties also sought review by the Supreme Court.\7\ The court
granted EPA's petition on May 22, 2000.\8\
---------------------------------------------------------------------------

\7\ The American Lung Association and the Commonwealth of
Massachusetts and State of New Jersey also filed petitions for
certiorari. In addition, groups led by the American Trucking
Associations and Appalachian Power Company filed conditional cross
petitions for certiorari.
\8\ The court also granted the industry cross petitions
regarding the consideration of costs in setting NAAQS on May 30,
2000.
---------------------------------------------------------------------------

II. In Summary, What Action Is EPA Finalizing Today?

Today, we are taking final action to rescind the findings that the
1-hour standard no longer applies in those areas where the Agency had
previously determined that the 1-hour standard had been attained. As a
result, the 1-hour standard will again become applicable in nearly
3,000 counties.
Where the 1-hour ozone standard again becomes applicable as a
result of this rulemaking, the attainment and nonattainment
designations and classifications applicable to such areas prior to the
determination of inapplicability will again apply. The designations are
inextricably linked to the applicability of the standard and were
removed solely because the standard no longer applied. See e.g.,
Interim Implementation Policy Statement, 61 FR 65752, 65754 (Dec. 13,
1996) (``the designations would remain

[[Page 45184]]

in effect so long as the current 1-hour ozone NAAQS remains in
effect''). Thus, since the only basis for removing the designations was
the inapplicability of the 1-hour standard, area designations for the
standard must also be reinstated upon reinstatement of the 1-hour
standard.
Given that the previous designations and classifications of these
areas were based upon the 1-hour ozone standard, which will again apply
as a result of this reinstatement action, EPA is amending the tables in
part 81 of the CFR to identify the designation and classification of
the area that applied prior to EPA's determinations that the 1-hour
standard no longer applied. The regulatory language located at the end
of this final rule amends the ozone tables in 40 CFR part 81 for each
State and provides a list of the areas affected by this rule. A copy of
these tables may also be viewed at the following Internet website
address: http://www.epa.gov/ttn/oarpg. In addition, the areas are
identified by air quality designations in the docket for this
rulemaking at Docket No. A-99-22.
The EPA's regulation, 40 CFR 50.9(b), provides that the 1-hour
ozone standard would no longer apply once EPA determined that an area
attained that standard. Today's action revises section 50.9(b) to
indicate that the 1-hour standard remains applicable to all areas
notwithstanding the promulgation of the 8-hour standard. Furthermore,
today's action establishes that after the 8-hour standard has become
fully enforceable under part D of title I of the CAA and subject to no
further legal challenge, the 1-hour standard set forth in section
50.9(a) will no longer apply to an area once EPA determines that the
area has air quality meeting the 1-hour standard.
In light of many areas' needs to quickly develop additional State
Implementation Plan (SIP) programs in response to the actions EPA is
finalizing today, the actions finalized today will become effective 90
days after today's publication for most areas. However, for areas that
were designated nonattainment prior to revocation but that currently
have clean air quality data sufficient to support a redesignation to
attainment, actions will not generally become applicable until 180 days
after today's publication.\9\ This additional time will allow areas to
submit redesignation requests and, if they do so, for EPA to take
appropriate rulemaking action on such requests prior to the
applicability date of this rule for the area.
---------------------------------------------------------------------------

\9\ The EPA notes that in the proposal for this action, EPA
proposed to make the final reinstatement effective after 90 days for
all areas, and specifically requested comment on this issue. Certain
commenters requested a longer delay in the effective date of the
rule, and EPA has agreed that for areas with clean data that were
previously designated nonattainment a longer period would be
appropriate. However, ``effective date'' is a term of art relating
to when rules published in the Federal Register will be incorporated
in the Code of Federal Regulations, and Office of Federal Register
requirements do not allow varying effective dates for entries in a
table. Therefore, this action as a whole will become effective for
all areas 90 days after publication. However, EPA will use the term
``applicability date'' in the rule to describe the date on which the
reinstatement of the 1-hour standard will begin to apply to an area.
That date will generally be 180 days after publication for those
areas with clean data previously designated nonattainment, as listed
in Table 1 of the preamble. In addition, if States are able to
submit redesignation requests and EPA is able to process such
requests to the point of final action prior to 180 days from
publication, the final action approving the redesignation may
provide that the applicability date of the reinstatement will be the
same date as the effective date of the redesignation approval, so
that the redesignations may take effect in a timely manner.
---------------------------------------------------------------------------

III. What Major Comments Were Submitted on the Proposed Rule and
What Are EPA's Responses to Such Comments?

In our October 25, 1999 proposal, we solicited comment on whether
EPA should rescind findings that the 1-hour ozone standard no longer
applies in certain areas, and if EPA acted to rescind the 1-hour ozone
standard, what the effects of a rescission would be. In section IV of
the proposal, EPA specifically requested comment on the effect of the
rescission for five types of areas: (1) Areas designated as attainment
with no violation since revocation; (2) areas designated attainment
(without maintenance plans) with violations since revocation; (3) areas
designated attainment (with maintenance plans) with violations since
revocation; (4) areas designated nonattainment with no violations since
revocation; and (5) areas designated nonattainment with violations
since revocation. Also, the Agency requested comment on the
programmatic effects of reinstatement, such as the applicability of new
source review (NSR) and conformity, as well as how to deal with
sanction and Federal Implementation Plan (FIP) clocks that were in
effect at the time of the revocations. A total of 72 comment letters
were received on the proposal. Most of the commenters generally
supported reinstating the 1-hour standard; however, they voiced
individual preferences as to how EPA should proceed to carry out this
action with respect to designations, planning obligations and timing.
For each of the relevant issues, the following discussion summarizes
EPA's proposed action, explains the approach EPA is adopting in this
final rule and responds to the major comments received. All comments
are addressed in the separate Response to Comments Document located in
the docket.

A. Reinstatement of the Applicability of the 1-Hour Ozone Standard and
the Designation and Classification That Existed for Each Area at the
Time EPA Determined the Standard No Longer Applied

The EPA generally proposed to reinstate the applicability of the 1-
hour standard in all areas for which EPA had taken action determining
that the standard no longer applied. In addition, EPA proposed that the
designation and classification for each such area would also be
reinstated. The EPA proposed to restore areas to the same position they
were in at the time EPA determined that the 1-hour standard no longer
applied, i.e., that the designation and classification that applied at
the time the 1-hour standard was revoked for an area would once again
apply upon reinstatement.
Comment: Several commenters believe that the Agency has no legal
authority to rescind findings that the 1-hour ozone standard no longer
applies in certain areas. Some commenters claim that EPA cited no
statutory authority for its action and that none exists. At least one
commenter contends that EPA's regulation at 40 CFR 50.9(b) does not
provide a basis for reinstating the 1-hour standard and challenges
EPA's statements that the basis for promulgating 40 CFR 50.9(b) was the
existence of an enforceable 8-hour standard.
Response: The EPA disagrees with the commenters' allegations that
EPA has no authority to rescind its findings that the 1-hour standard
no longer applies in certain areas. The EPA made those findings in
accordance with its rule at 40 CFR 50.9(b), which provided that the 1-
hour standard would no longer apply once an area attained that
standard. The EPA promulgated that regulation using its general
rulemaking authority under section 301(a) of the CAA and thus has
authority to revise that regulation (and to revise or repeal actions
taken pursuant to that regulation) under that same authority. The
changed circumstances regarding the status of the 8-hour standard
provide ample support for EPA to take this regulatory action under
section 301(a).
Sections 108 and 109 of the CAA provide for the promulgation or
revision of NAAQS on a periodic basis. However, those provisions are
silent regarding how areas should transition

[[Page 45185]]

from implementation of one NAAQS for a pollutant to a revised, more
stringent NAAQS for the same pollutant.\10\ Where, as in the rule
promulgating the revised 8-hour NAAQS, EPA determines not to retain the
pre-existing standard as an independent NAAQS, EPA must determine how
areas should transition away from the pre-existing NAAQS. Since the CAA
does not include specific provisions addressing this transition, EPA
relied on its general rulemaking authority under section 301(a) of the
CAA. See 62 FR 38894, July 18, 1997. Section 301(a) provides that the
Agency has authority ``to prescribe such regulations as are necessary
to carry out'' its functions under the CAA. In general, the statutory
authority for promulgating a regulation also provides authority for an
Agency to revise that regulation. The EPA is relying on its general
rulemaking authority under section 301(a) to rescind the findings that
the 1-hour standard no longer applies.
---------------------------------------------------------------------------

\10\ Section 172(e) provides guidance for transitioning from a
more stringent NAAQS for a pollutant to a less stringent NAAQS for
the same pollutant.
---------------------------------------------------------------------------

The present circumstances provide ample support for EPA to take
this action rescinding its earlier determinations. The EPA promulgated
40 CFR 50.9(b) based on the existence of an implementable 8-hour
standard. In promulgating a revised 8-hour standard, EPA determined
that it did not need to retain a separate 1-hour standard in order to
protect the public health with an adequate margin of safety and to
protect public welfare (62 FR 38863, July 18, 1997). Thus, EPA needed
to consider how to transition away from the existing 1-hour standard to
the revised 8-hour standard. See e.g., Proposed Interim Implementation
Policy, (61 FR 65752, December 13, 1996). In the final rule
promulgating the revised 8-hour standard, EPA concluded that Congress
intended areas to remain subject to the planning requirements of
subpart 2 \11\ of the CAA for as long as they continued to have air
quality not meeting the 1-hour standard. In order to facilitate the
continued applicability of subpart 2 to areas that had not yet met that
standard, EPA determined to delay removal of the 1-hour standard from
its regulations by promulgating 40 CFR 50.9(b). It is clear from the
context of the rule and the statements in the preamble to the final 8-
hour NAAQS rule that the decision to find that the 1-hour standard no
longer applied was based on the existence of an enforceable 8-hour
standard that was protective of public health and welfare, such that
the 1-hour standard would no longer be necessary to protect public
health and welfare. (62 FR 38873, July 18, 1997.)
---------------------------------------------------------------------------

\11\ Subpart 2 of part D of title 1 provides detailed
requirements for certain ozone nonattainment areas. These provisions
were enacted in 1990 in response to the States' continued failure to
meet the ozone standard. Rather than providing continued flexibility
and a one-size-fits-all approach, Congress created a tiered planning
scheme that provided more and tougher requirements for areas with
significant ozone problems, but also provided more time for these
areas to meet the standards.
---------------------------------------------------------------------------

However, because the court decision has raised doubts about the
enforceability of the 8-hour standard and EPA's ability to implement
the standard fully at this time, the basis for the regulation revoking
the applicability of the 1-hour standard in certain areas no longer
exists. Contrary to what EPA believed would occur at the time it
promulgated 40 CFR 50.9(b), generally areas are not currently moving
forward to implement the 8-hour standard due to the uncertainty created
by the litigation over the ozone NAAQS. Thus, EPA believes that it is
necessary at this time to retain the 1-hour standard in all areas to
protect public health and welfare at least until the status of the 8-
hour standard and any issues concerning its enforceability have been
fully resolved.\12\
---------------------------------------------------------------------------

\12\ The fact that EPA's regulation at 40 CFR 50.9(b) does not
reference the 8-hour standard is not controlling for determining the
underlying basis for EPA's promulgation of that regulation. The fact
that 50.9(b) was promulgated simultaneous with the 8-hour standard
and placed in the subchapter of the CFR governing NAAQS is
sufficient evidence that Sec. 50.9(b) was premised on the existence
of the 8-hour ozone standard. Furthermore, it is clear from the
preamble that EPA believed that the 8-hour standard would be
enforceable, (62 FR 38856, July 18, 1997).
---------------------------------------------------------------------------

Comment: Some commenters believe that the proposed action to
reinstate the 1-hour ozone standard constitutes promulgation of a new
or revised NAAQS under section 109 of the CAA and that the action is
therefore subject to a public hearing under section 307(d). Other
commenters contend that EPA must or should vacate the 8-hour standard
before EPA can reinstate the applicability of the 1-hour standard.
These and other commenters contend that section 109 contemplates only a
single air quality standard for a particular pollutant in any given
area and, therefore, object to having dual standards apply. They also
claim that the existence of two ozone standards is confusing.
Response: The EPA does not believe that the action to reinstate the
1-hour standard constitutes the promulgation of a new or revised NAAQS
under section 109 of the CAA. The 1-hour standard EPA is reinstating
today is the same 1-hour standard that has been in existence since its
original promulgation on February 8, 1979 and that continues to be a
part of EPA's regulations at 40 CFR 50.10, (44 FR 8202). The EPA is not
revising that standard in any way. The EPA is merely reinstating the
applicability of that standard in certain areas. Unlike a regulatory
action promulgating a new or revised NAAQS, this rulemaking is not
concerned with selecting the appropriate level or form of ozone
standards requisite to protect public health and welfare. The
particular processes specified in sections 108 and 109, requiring the
development of detailed scientific assessments and consultation with
science advisory boards, are not implicated by this action. The EPA
undertook those processes when it promulgated the 1-hour standard in
1979. This action does not purport to revise or re-promulgate that
standard; it only specifies the applicability of the existing 1-hour
standard, which is specified in section 50.10, to certain areas.
Because this action rescinding a previous regulatory determination
and revising the regulation governing the transition from the 1-hour to
a revised 8-hour NAAQS does not constitute either an amendment or
revision to either the 1-hour or the 8-hour ozone NAAQS, EPA disagrees
with the commenters that the procedural provisions in section 307(d)
are triggered by section 307(d)(1)(A) (requiring compliance with
section 307(d) for all rules promulgating or revising any NAAQS). Since
the administrative requirements of section 307(d) do not apply, EPA has
complied with the public notice and comment process specified under the
Administrative Procedure Act, 5 U.S.C. 553, which does not require the
Agency to hold a public hearing.
Nor does EPA agree that the proper approach is to vacate the 8-hour
standard. In the ATA decision, the D.C. Circuit did not dispute the
public-health basis for the NAAQS and did not vacate the 8-hour
standard. The EPA sees no reason to take such an action on its own. The
EPA has filed with the Supreme Court a petition for review of the D.C.
Circuit's decision. The EPA sees no need to vacate the 8-hour standard
for the purpose of revising the transition scheme from the 1-hour
standard to the 8-hour standard. Because the CAA does not provide how
EPA must transition from one standard for a pollutant to a revised,
more stringent standard for that same pollutant, EPA continues to
believe it has authority to establish and to revise the appropriate
transition scheme. Due to the uncertainty created

[[Page 45186]]

by the court's opinion, EPA believes it is a reasonable exercise of its
authority to revise the transition scheme by reinstating the
applicability of the 1-hour standard and the associated designations
and classifications. For these reasons, EPA does not agree that it must
vacate the 8-hour standard in order to reinstate the applicability of
the 1-hour standard.
To the extent the commenters are concerned about the existence of
two NAAQS for the same pollutant, EPA made the decision in the 1997
NAAQS rulemaking by determining to retain the 1-hour standard until
areas met that standard. As provided above, EPA is not taking action to
revise or promulgate a revised NAAQS in this rule and is not re-opening
its previous decision that the statute allows the applicability of more
than one NAAQS for a pollutant, such as ozone.
Comment: Some commenters claim that EPA cannot restore the
designation for areas except through one of the designation processes
provided under section 107 of the CAA. Some commenters contend that EPA
should treat these designations as initial designations under section
107(d)(1) and that EPA should provide time for Governors to make
recommendations before EPA may designate areas. Other commenters
contend that EPA must use the redesignation provisions under section
107(d)(3). Under that provision, they contend, EPA must notify the
Governor first of its intent to redesignate and then must rely on
current air quality data.\13\ Some of these commenters agree with EPA
that the designation in place at the time EPA revoked the standard
should be put back into place. Other commenters suggest that EPA cannot
consider air quality data from the period when the standard did not
apply and that EPA should reinstate designations based on air quality
data from the period after the standard is reinstated.
---------------------------------------------------------------------------

\13\ Other commenters, without referencing any specific
statutory authority, also claim that EPA should use current air
quality data to designate areas.
---------------------------------------------------------------------------

Response: The EPA does not believe it needs to go through the
procedures of section 107 of the CAA to reestablish the designations
that were in place prior to revocation of the 1-hour standard. In this
action, EPA is reversing its revocation of the standard because the
recent court decision has called into question the underlying bases for
that action. In the revocation action, EPA did not change an area's
designation for the 1-hour standard, but determined that since the 1-
hour standard no longer applied to an area, the designation associated
with that standard also no longer applied.\14\
---------------------------------------------------------------------------

\14\ In revoking the standard, EPA did not redesignate areas
pursuant to section 107 and did not require areas to meet the
redesignation requirements of section 107(d)(3)(E), such as
development of a maintenance plan. In fact, EPA has been challenged
on two of the revocation rules for not following, and not requiring
States to follow, redesignation procedures. Environmental Defense
Fund v. EPA, (D.C. Cir., No. 98-1363); Appalachian Mountain Club v.
EPA, (1st Cir., No. 99-1880).
---------------------------------------------------------------------------

As explained above, EPA's action today is not the promulgation of
new or revised NAAQS. Therefore, the initial designation provisions in
section 107(d)(1), which apply only upon promulgation of a new or
revised NAAQS, do not apply.
Nor is EPA redesignating areas for purposes of the 1-hour standard.
These areas currently do not have in place a designation for the 1-hour
standard. The provisions in section 107(d)(3), which apply only to
redesignations from attainment or unclassifiable to nonattainment or
from nonattainment to attainment simply do not apply where, as here,
there is not a current designation in place for a standard.
The EPA's primary action through this action is to reinstate the
applicability of the 1-hour standard. At the time EPA promulgated 40
CFR 50.9(b), it determined that the designations should follow the
applicability of the 1-hour standard and that the current designation
was inextricably linked with the applicability of the 1-hour standard.
Therefore, just as EPA determined that an area's designation no longer
applied once the 1-hour standard on which it was based no longer
applied, the reinstatement of the 1-hour standard necessarily brings
back the applicability of the designation. Similarly, as EPA relied on
its general rulemaking authority to revoke the standard and thus the
area's designation, EPA is relying on that same authority to reverse
the action taken in its earlier rule. Once areas have a designation for
the 1-hour standard in place, EPA may redesignate those areas if they
meet the requirements of section 107(d)(3)(E). As discussed in section
III.F, below, EPA will consider redesignating those areas that have
clean air quality data based on the three most recent years of data and
that submit a redesignation request meeting the requirements of section
107(d)(3)(E).
Finally, some commenters suggest that EPA is prohibited from
considering air quality data that became available after EPA revoked
the standard. The EPA disagrees with this comment. Because EPA is
reinstating the designations that existed at the time EPA revoked the
standard, this rulemaking does not reflect more recent air quality
data. However, in future actions to redesignate areas, EPA intends to
consider all relevant air quality data including data that became
available during the revocation. To the extent these commenters
continue to have concerns about this issue, they can raise them in any
future rulemaking action EPA may take to redesignate an area on the
basis of that data.
Comment: A few commenters stated that we cannot rely on the
argument that the 8-hour standard cannot be enforced as the basis for
revocation since this is not supported by the Court's October 29, 1999,
decision on rehearing. In the October 29 opinion, the Court retracted
its earlier conclusion that ``the 8-hour standard cannot be enforced,''
providing instead that the 8-hour standard ``can be enforced only in
conformity with subpart 2'' of part D of title I of the CAA. Compare
175 F.3d at 1057 with 195 F.3d at 10. Some commenters also suggest that
it is too late for us to reconsider the revocations and to reinstate
the applicability of the 1-hour standard. Most commenters, however,
support reinstatement on the basis of continued uncertainty regarding
the 8-hour standard.
Response: The EPA believes that the uncertainty engendered by the
litigation surrounding the 8-hour standard justifies reinstating the 1-
hour standard. It is true, that on rehearing, the Court revised its
original opinion to indicate that EPA can enforce the 8-hour standard
in conformity with subpart 2 of the CAA. However, in that same
sentence, the Court provided that it was remanding the 8-hour standard.
The Court did not vacate the 8-hour standard because ``the parties have
not shown that the standard is likely to engender costly compliance
activities.'' As the petitions for certiorari before the Supreme Court
demonstrate, there continues to be uncertainty regarding when the
standard could be implemented in light of the ongoing litigation.\15\
Because of the continuing litigation and the differing views of the
many parties to the litigation, EPA is not currently taking any action
that could be construed as inconsistent with the

[[Page 45187]]

Court's decision.\16\ In light of the continuing uncertainty regarding
EPA's authority to implement the 8-hour standard, EPA believes it is
prudent to reinstate the 1-hour standard to ensure public health
protection from ozone.
---------------------------------------------------------------------------

\15\ In addition to EPA, two other parties have requested that
the Supreme Court review portions of the D.C. Circuit's decision
regarding the ozone and particulate matter NAAQS. Other parties have
opposed Supreme Court review of the implementation issues. In their
papers before the Court, several of these parties have suggested
that EPA is barred from enforcing the more stringent 8-hour NAAQS,
while others raise concerns that the Court's opinion is unclear
regarding the enforceability of the 8-hour standard.
\16\ For example, EPA has stayed the applicability of its final
regulatory determinations under section 126 of the CAA to the extent
they were based on the 8-hour NAAQS. (65 FR 2674, January 17, 2000).
Similarly, EPA recently proposed to stay the 8-hour basis of its
NO_X SIP call rule, which calls on 22 States and the
District of Columbia to reduce emissions of nitrogen oxides that
contribute to ozone problems in other States. (65 FR 11024, March 1,
2000).
---------------------------------------------------------------------------

Contrary to the suggestions of some commenters, EPA does not
believe it is too late to rescind the revocations of the 1-hour
standard. The commenter does not cite and EPA is unaware of any
limitation on when an Agency may change a regulation based on new
information. The EPA acted quickly in response to the uncertainty
raised by the Court's decision, proposing action only 5 months after
the original decision by the court. During that time, EPA was assessing
the impacts of the opinion on implementation of the 8-hour standard,
determining options for rehearing and appeal, and developing the
proposed rule to rescind the revocations of the 1-hour standard. Based
on requests for an extension of the comment period, EPA provided a
comment period of 60 days on this action. Thus, EPA is acting in a
timely fashion by issuing this rule approximately a year afer the court
issued its original decision.
Comment: A few commenters suggested that EPA was proposing to
reinstate the standard in too many areas. One set of commenters noted
that EPA's goal of providing protection in areas now violating the 1-
hour standard could be accomplished by reinstating the standard only in
those areas that were violating the 1-hour standard. Other commenters
suggested that we not reinstate the 1-hour standard in States that have
adopted the 8-hour standard or where the most recent data for an area
indicate that it would be designated attainment for the 8-hour
standard. These commenters are concerned that resources will be wasted
on meeting the 1-hour standard rather than the more protective 8-hour
standard.
Response: The EPA determined that it is critical to have a fully
enforceable standard for ozone in each area of the country in order to
protect the public health and welfare and to minimize public confusion.
The EPA believes that it is important to have a fully-implementable
ozone standard in place in order to ensure adequate protection of
public health. A fully enforceable 1-hour standard will ensure that
sufficient control measures remain in place to prevent violations in
areas attaining the standard and to continue improvements in air
quality in areas not attaining the standard. The options presented by
the commenters would not result in the applicability of a fully-
enforceable ozone standard and thus could erode public health
protection for people living and working in areas that might violate
the standard in coming ozone seasons.
With respect to those commenters that suggest that EPA not
reinstate the standard in areas that have adopted the 8-hour standard,
EPA is concerned, in light of the ATA decision, that it will be unable
to enforce fully the 8-hour standard in the short term. Without a fully
enforceable, Federal 8-hour standard, EPA does not have the ability to
require States to implement an 8-hour standard. This is true even in
States that may have adopted the 8-hour standard as a State rule. Since
State adoption of the 8-hour standard does not ensure implementation
and enforcement of that standard in conformity with Federal
requirements for clean air, EPA believes it is necessary to reinstate
the 1-hour standard in all areas pending resolution of litigation over
the 8-hour NAAQS. The EPA acknowledges that it may be more efficient to
concentrate resources on planning to implement a more protective 8-hour
standard, but EPA lacks the ability to require States to do so at this
time. For these reasons, EPA believes that the existence of the 8-hour
standard does not provide the same certainty of public health
protection as does the 1-hour standard at this time.
Finally, with respect to the comment that EPA not reinstate for
areas that will be designated attainment for the 8-hour standard, EPA
has not designated any areas for the 8-hour standard. The States have
not recommended boundaries for purposes of the 8-hour standard and EPA
has not yet determined boundaries or designated any 8-hour areas. In
fact, EPA guidance on the determination of boundaries was issued only
recently. (Boundary Guidance on Air Quality Designations for the 8-Hour
Ozone National Ambient Air Quality Standards (NAAQS or Standard), March
28, 2000). The EPA has advised States to consider the guidance and make
recommendations to EPA by June 30, 2000. The EPA must then respond to
those recommendations and give States 4 months comment on its response.
Only after this process could EPA make final designations. Given the
many steps that must occur before EPA promulgates designations for the
8-hour standard, EPA believes it is far too early to presume precisely
which areas would be designated attainment for the 8-hour standard.

B. Revision to 40 CFR 50.9(b) to Provide That EPA Will Again Determine
the 1-Hour Ozone Standard No Longer Applies to an Area Once EPA's
Authority to Implement and Fully Enforce the 8-Hour Standard Is No
Longer in Question

The EPA proposed to revise 40 CFR 50.9(b) to provide that once the
8-hour ozone standard is fully enforceable and no longer subject to
legal challenge, the 1-hour standard will no longer apply to an area if
EPA determines that the area has air quality meeting the 1-hour
standard.\17\ The EPA's final rule adopts this position.
---------------------------------------------------------------------------

\17\ If the 8-hour standard promulgated in July 1997 does not
become enforceable because of Agency action taken in response to any
unappealable decision by the court in the ATA v. EPA litigation,
then the second sentence of 40 CFR 50.9(b) would not have any legal
effect. As appropriate, EPA could reconsider this regulation at the
time it takes any action in response to an unappealable decision.
---------------------------------------------------------------------------

Comment: Some commenters disagree with EPA's proposed revision to
Sec. 50.9(b). These commenters feel that the promulgation of an 8-hour
standard should not be the basis for revoking the applicability of the
1-hour standard. Some of the commenters believe that removing the
applicability of a NAAQS and associated control measures based solely
on air quality is inconsistent with the law and that we should consider
both the 1-hour and 8-hour ozone standards. Some commenters believe
that future revocations should not be allowed without first following
the redesignation process as prescribed by the CAA. Other commenters
suggest that once the 8-hour ozone standard is enforceable, we should
revoke the 1-hour standard everywhere regardless of what the air
quality is. Finally, one commenter claims that EPA should not amend
section 50.9(b) now since the 8-hour standard may never be enforceable.
Response: The EPA believes that it has the authority upon issuance
of a new or revised standard to determine the continued validity of the
pre-existing standard and when, if ever, it should no longer apply. In
the final rule promulgating the 8-hour standard, EPA determined that
the 1-hour standard was no longer necessary to protect public health
and welfare in light of the revised 8-hour standard, which States would
be required to implement and enforce. However, EPA also determined that
Congress intended areas that remained nonattainment for the 1-hour
standard to meet the requirements of subpart 2, until the 1-hour
standard is attained. As EPA explained in the

[[Page 45188]]

preamble to the NAAQS rule, section 109 of the CAA clearly authorizes
EPA to promulgate revisions to a standard, which necessarily includes
the authority to revoke previous standards that have been revised (62
FR 38857, July 18, 1997). On the other hand, subpart 2 of the CAA sets
out numerous requirements specifically applicable to areas not
attaining the 1-hour ozone standard. To accommodate both of these
provisions, EPA concluded that after promulgation of the 8-hour
standard, subpart 2 must continue to apply as a matter of law in each
area until the 1-hour standard is attained (62 FR 38873). Thus, to
facilitate continued applicability of the subpart 2 requirements, EPA
established a transition scheme in 40 CFR section 50.9(b) that provided
the 1-hour standard would continue to apply until an area had air
quality meeting the 1-hour standard.
The EPA does not agree that in order to determine a pre-existing
standard no longer applies, EPA must require areas to meet the
requirements for redesignation and formally redesignate an area from
nonattainment to attainment under section 107(d)(3). As a general
matter, Congress has not specified any procedure for determining that a
pre-existing NAAQS no longer applies once EPA promulgates a revised
standard. Moreover, although Congress gave some guidance on how to
transition to a less stringent NAAQS, see CAA section 172(e), it did
not provide clear guidance on how to transition to a more stringent
NAAQS. The EPA believes that in determining how to transition to a
revised NAAQS, it must make common-sense decisions, considering the
intent of Congress in light of the statutory scheme, including how best
to ensure public health protection without imposing unduly burdensome
requirements on States and sources.\18\
---------------------------------------------------------------------------

\18\ EPA's scheme for transitioning to the 8-hour ozone standard
is consistent with the Agency's approach in the one other case where
it promulgated a more stringent NAAQS revision. See 52 FR 24672
(July 1, 1987). When EPA revised the particulate matter standard to
change the indicator from total suspended particulates (TSP) to
particulate matter with a diameter of 10 microns or less (PM-10), it
retained the TSP designations for a limited purpose because the
statutory limitations for certain areas under the Prevention of
Significant Deterioration (PSD) program were linked to TSP
designations. See CAA section 163. Congress subsequently codified
EPA's decision in section 107(d)(4)(B) of the CAA. Similarly, EPA
here is retaining the 1-hour standard and associated designations
for purposes of continued application of subpart 2 of the CAA, until
the purpose of subpart 2--attainment of the 1-hour standard--is met.
---------------------------------------------------------------------------

With respect to the transition from the 1-hour standard to the 8-
hour standard, EPA determined that Congress intended areas to remain
subject to the 1-hour standard until such time as that standard is met.
Since all areas of the country were subject to the revised, more
stringent 8-hour standard, EPA determined that it did not make sense to
require areas that had met the 1-hour standard but remained designated
nonattainment to complete a maintenance plan since generally these
areas would be required to develop an attainment plan for the more
stringent 8-hour standard. The EPA continues to believe that, if a
fully enforceable 8-hour standard were in effect, it would be
unreasonable to require States to demonstrate that an area will
maintain the 1-hour standard for 10 years (with a later update for a
subsequent 10 years) when these areas would be developing attainment
plans and, ultimately, maintenance plans for the more stringent 8-hour
standard.
This interpretation is consistent with the approach Congress
employed in the one area where the statute does address revocation of a
prior standard. Section 172(e) of the CAA provides that where EPA
relaxes a standard, it must require all areas that have not yet
attained the more stringent prior standard to provide for controls that
are at least as stringent as those that applied to areas designated
nonattainment of the prior standard. This provision both clarifies that
Congress intended EPA to revoke standards and associated control
requirements in certain circumstances where they have been revised, and
that an appropriate criterion for determining when a prior standard
should be revoked is whether or not an area has attained that standard.
Congress did not, however, require redesignation of areas with
development of maintenance plans prior to removal of control
obligations. Rather, Congress required only that control measures
continue to apply until an area has attained a prior standard and
implicitly allows for revocation of the prior standard.
The EPA also disagrees with the commenter who suggests that EPA
should not amend Sec. 50.9(b) because it has been struck down by the
court and that the 8-hour standard might never be enforceable. The EPA
disagrees with the claim that the court struck down 40 CFR 50.9(b). The
court did not vacate any aspect of EPA's July 1997 rulemaking, which
included the promulgation of section 50.9(b).\19\ The EPA believes that
its proposed revision to section 50.9(b) addresses the contingency that
the 8-hour standard may never become enforceable. The EPA believes that
it is better to promulgate revisions to section 50.9(b) at this time so
that interested parties are aware of EPA's planned transition approach
if and when the 8-hour standard becomes fully enforceable.
---------------------------------------------------------------------------

\19\ Furthermore, no party in the ATA case challenged EPA's
promulgation of 40 CFR 50.9(b) and the court did not address this
regulatory provision in either its May 14, 1999 or its October 29,
1999 decisions.
---------------------------------------------------------------------------

Finally, for the reasons explained above, EPA believes that subpart
2 continues to apply as a matter of law to all areas that have not yet
attained the 1-hour standard. Therefore, EPA does not believe it has
the authority to determine the 1-hour standard inapplicable to any area
that has not yet attained that standard, even after the 8-hour standard
has become fully enforceable.

C. Areas Designated as Attainment With No Violations Since Revocation

The EPA proposed that upon reinstatement of the standard, areas
designated as attainment with no violations after revocation would not
be subject to any new planning requirements under subpart 2 of the CAA,
beyond continuing compliance with any requirements in an approved
maintenance plan. The EPA is adopting this position in today's action.
Comment: Some commenters contend that all areas designated as
attainment should be treated on an equal basis. The EPA should either
require all attainment areas to have maintenance plans, including the
obligation to comply with conformity, or free all areas from the
maintenance plan requirement.
Response: The EPA does not have the authority to require all areas
designated as attainment either to have a maintenance plan or to
relieve them of that obligation. The CAA specifically provides that
areas seeking redesignation from nonattainment to attainment must
develop and submit maintenance plans. Upon redesignation, these areas
are required to continue to implement their maintenance plans,
including complying with the conformity provisions. Areas that were
initially designated as attainment after the 1990 CAA Amendments are
not subject to this requirement. In addition, section 176(c)(5)(B) of
the CAA makes clear that areas with maintenance plans continue to be
subject to conformity and that areas that have historically been
designated as attainment are not subject to conformity.

D. Areas Designated Attainment (Without Maintenance Plans) With
Violations Since Revocation

The EPA proposed to provide areas designated attainment without

[[Page 45189]]

maintenance plans, that have had violations since revocation, a
reasonable time to come back into attainment prior to taking action to
designate them as nonattainment. There are only four areas which fall
into this category: Berrien Co., MI; Hamilton Co., IN; Hamilton Co.,
TN; Rowan Co., NC.
Comment: Several commenters asked that we define what is a
``reasonable time frame'' to bring areas back into attainment. Some
commenters reference measures that States have already taken to address
ozone problems.
Response: The CAA does not mandate that EPA redesignate areas from
attainment to nonattainment. Rather, section 107(d)(3)(A) provides the
general criteria that EPA may consider in determining whether to
redesignate an area.\20\ In particular, EPA may consider air quality
data, planning and control considerations or any other air-quality
related considerations.
---------------------------------------------------------------------------

\20\ For areas designated as nonattainment seeking redesignation
to attainment, section 107(d)(3)(E) sets forth additional criteria
that must be met before EPA may redesignate the area.
---------------------------------------------------------------------------

The Agency commends areas for any initiatives they may have taken,
such as voluntary emission reduction programs, to help improve air
quality. The EPA will consider this information in determining whether
and when to move forward with a redesignation to nonattainment. States
should work with the appropriate EPA Regional Offices to determine
whether additional measures are necessary to address a recent
violation.
To the extent additional measures are needed, EPA believes that it
is reasonable for States to adopt measures to address any violations
within 6-9 months of the effective date of this final action. The EPA
is recommending 6-9 months as the presumptive period for action,
however, each State should work with the relevant EPA Regional Office
to develop a strategy for specific areas. States have been on notice of
EPA's planned reinstatement of the standard and should have begun an
analysis of measures to address any violation. In addition, since
reinstatement for these areas will not be effective until 90 days after
publication of this final action in the Federal Register, this approach
will allow States 9-12 months from promulgation of this final rule to
adopt any necessary measures and well over a year from the time of
EPA's proposal to reinstate the standard. The EPA believes that this
period is comparable to the 1-year time period provided under section
179(d) for States to adopt measures based on a finding that the State
failed to attain the standard.

E. Areas Designated Attainment (With Maintenance Plans) With Violations
Since Revocation

For areas designated attainment with maintenance plans and with
violations since revocation, EPA proposed that the contingency measures
in the area's approved SIP should be implemented to address any
violations of the 1-hour ozone standard. If a State had removed any
contingency measures after EPA determined the 1-hour standard no longer
applied, EPA proposed the State should place the contingency measure
back into the SIP. There are seven areas which fall into this category:
Charlotte-Gastonia, NC; Huntington-Ashland, WV-KY; Knoxville, TN;
Nashville, TN; Portland-Vancouver Air Quality Management Area, OR-WA;
Richmond, VA; Sheboygan, WI.
Comment: Several commenters question whether it is appropriate to
require States to implement contingency measures and question whether
contingency measures will provide any real air quality benefits. They
disagree that automatic implementation of such measures is the correct
solution to addressing the current air quality problem. Some commenters
believe that since the 1-hour standard did not apply in the areas after
revocation, the areas cannot be considered to be violating the 1-hour
standard based on data from that time; thus in their view, violations
that occurred after revocation but prior to reinstatement cannot
trigger contingency measures. Some commenters argue that even if a
violation occurred during the period in which the standard was revoked,
the most recent 3 years of air quality data should have precedence.
They state that if those data indicate the area is not violating the
standard, the State should not be required to implement contingency
measures.
In addition, some commenters were concerned that the schedule
specified in the SIPs for implementation of contingency measures is
often triggered as of the date of the violation. Thus, under these
SIPs, some portion of the implementation period may already have passed
by the time the reinstatement becomes effective.
Other commenters claim that EPA should use its authority under
section 110(k)(6) to place deleted contingency measures back into the
SIP. Section 110(k)(6) provides that EPA may revise its prior approval
removing the contingency measures if it determines that the approval
action was in error.
Response: Section 175A(d) of the CAA requires that a maintenance
plan include such contingency measures as are necessary to promptly
correct any violation of the NAAQS that occurs after redesignation of
the area. The EPA believes that areas designated as attainment that
have maintenance plans in place and that have had violations of the
NAAQS since revocation, are required by the CAA and by their approved
SIPs to move forward to implement contingency measures. Since the
purpose of these measures is to protect public health, EPA believes it
is appropriate to require areas to implement contingency measures to
ensure that future air quality will meet or be lower than the NAAQS.
The EPA has allowed States a great deal of flexibility with respect
to contingency measures. First, EPA has allowed flexibility in terms of
the selection and adoption of contingency measures for the maintenance
plan. The EPA does not require that contingency measures be fully
adopted in order for the maintenance plan to be approved. The
maintenance plan need only ensure that the contingency measures be
adopted expeditiously once they are triggered. (Procedures for
Processing Requests to Redesignate Areas to Attainment, September 4,
1992, John Calcagni).
In addition, when an area violates the standard, States have
discretion in selecting which of the contingency measures in the
approved maintenance plan should be implemented. In the past, EPA has
allowed States to substitute and implement new, more appropriate and
effective contingency measures. (64 FR 28753 and 64 FR 28757, May 27,
1999). The EPA would allow States with areas violating the standard to
do so here through the SIP process, if substitution of measures would
not unreasonably delay air quality benefits. Therefore, if, as at least
one commenter suggests, existing, approved contingency measures may no
longer be appropriate or effective, the State may seek a substitution.
However, the fact that existing contingency measures may not be
effective or appropriate does not support a decision not to require
implementation of contingency measures to address the air quality
problem.
Finally, although EPA has indicated that it would provide a
reasonable period of time for violating attainment areas without
maintenance plans to correct their air quality problem before
designating them to nonattainment, EPA does not believe it has the
ability to delay the triggering of the States' obligation to select and
adopt contingency measures for areas with maintenance plans that are
experiencing violations. The CAA contemplates that

[[Page 45190]]

contingency measures will be implemented ``promptly'' in such areas. In
addition, the terms of the maintenance plans themselves require
adoption and implementation of contingency measures upon violations.
Thus, the CAA requires areas to adopt appropriate contingency measures
once violations occur. States may submit SIP revisions to substitute
appropriate measures at any time.
The EPA disagrees that violations are not valid if they occurred
during the period when the 1-hour standard did not apply for an area.
The fact that an air quality standard does not apply during a period of
time does not invalidate air quality data gathered at that time or
invalidate the exceedances or violations demonstrated by that data. In
fact, the statutory period for initial designations belies that
interpretation. Under section 107(d)(1), Governors must recommend
designations within 1-year of promulgation of a standard and EPA must
designate areas within 2 years of promulgation. For standards that are
measured over a period of longer than 2 years, such as the 1-hour and
8-hour ozone standards, EPA would necessarily be required to consider
monitoring data that preceded promulgation of the standard in making
designations. In addition, the State and sources are not unreasonably
disadvantaged. The EPA is not requiring that the time for States to
implement contingency measures runs from the time of the violation, but
rather from the effective date of the reinstatement of the standard.
This approach is consistent with the approach EPA is taking
concerning tolling of applicable clocks for conformity obligations and
sanctions. As EPA states elsewhere in this notice (sections III.I and
III.J), EPA believes that clocks related to the timing of conformity
determinations and sanctions should not be considered to have run
during the period that the 1-hour standard was not applicable to an
area. It would be unfair to areas to have such clocks expire during a
time that the area was not subject to the planning obligations
associated with the clocks. Thus, EPA has concluded that any such
clocks would be tolled during the time the standard was not applicable.
When this rule becomes applicable, the clock will begin to run again
based on whatever time remained when EPA revoked the standard for an
area. Similarly, EPA believes that the duty to implement contingency
measures should be triggered on the effective date of this
reinstatement action rather than the date of any past violation.
If an area has a SIP in which the timing for contingency measures
is triggered on the date of the violation, EPA believes that it would
be appropriate to interpret the violation as occurring on the effective
date of the reinstatement. If States still remain concerned about the
approved language in existing SIPS regarding the timing for triggering
contingency measures, they should work with the relevant EPA Regional
Office to determine an appropriate manner to address the issue. Since
the 1-hour standard was not in effect for the area during the
revocation period, EPA does not believe that the area should be subject
to a shorter time than contemplated in the State's adoption and EPA's
approval of the SIP.
With respect to commenters that claim that an area may have had a
violation (during 1996-1998) and once again is attaining (during 1997-
1999), EPA believes that such areas should work with the relevant EPA
Regional Office to determine an appropriate course of action. If there
are additional control measures that applied during 1999, but did not
apply during the period of the violation, it may not be necessary to
implement further contingency measures at this time.
The EPA allowed States to remove contingency measures from approved
SIPs where they were linked to the 1-hour standard or air quality ozone
concentrations and EPA had taken action to determine that the 1-hour
standard no longer applied. See ``Guidance for Implementing the 1-Hour
Ozone and Pre-Existing PM10 NAAQS,'' from Richard D. Wilson, Acting
Assistant Administrator for Air and Radiation, December 29, 1997. The
EPA believed that such revisions would be consistent with section
110(l) of the CAA since EPA was determining that the 1-hour standard no
longer applied and, therefore, removal of the contingency measures
would not interfere with any applicable requirement concerning
attainment and reasonable progress, or any other applicable requirement
of the CAA. Id.
Because EPA believes it is now appropriate and necessary to
reinstate the 1-hour standard, EPA believes it is no longer appropriate
for States not to have those contingency measures in the approved SIP.
States will need to move forward to put contingency measures back into
the SIP. The EPA believes that States should have some discretion in
selecting these contingency measures considering what measures would be
appropriate, and adopting such measures, as necessary. Thus, at this
time, EPA is not moving forward to use section 110(k)(6) to retract its
earlier approval of SIP revisions removing contingency measures. Since
EPA is not now proposing to move forward under section 110(k)(6), EPA
is not addressing whether that provision provides the legal authority
to take the action suggested by the commenters.

F. Areas Designated Nonattainment With No Violations Since Revocation

For areas designated nonattainment with no violations since the
standard was revoked in these areas, EPA proposed that the
nonattainment designation would again apply, but recommended that the
State submit a redesignation request that meets the requirements of
section 107(d)(3)(E). In addition, EPA noted that its May 10, 1995,
``Clean Data Policy'' could provide relief from some subpart 2 measures
for these areas as long as they continued to have clean data. However,
other subpart 2 requirements would apply unless and until an area was
redesignated to attainment. There are 45 areas which fall into this
category. The following table (Table I) lists the areas in this
category:

Comment: A number of commenters were opposed to reinstating prior
designations and classifications, particularly in the case of areas
that were designated nonattainment at the time of the revocation and
that have remained clean. They want EPA to consider current monitoring
data as the basis of an area's designation. These commenters claim that
EPA's proposed approach creates inequities among the various types of
areas where the standard would be reinstated. For example, they point
to areas that will be designated attainment but that are violating the
1-hour standard. The commenters contend that it is inequitable that
those areas will not be subject to subpart 2 control requirements,
including new source review and conformity, but that certain
nonattainment areas that have remained clean since revocation will be.
One commenter did not seem to object to this approach, but recommended
that EPA approve pending redesignation requests within 1 to 3 months of
the final reinstatement.
Other commenters supported EPA's proposal to restore the
designations and classifications that applied at the time of the
revocation action. Several of these commenters claimed that EPA should
not or could not consider violations that occurred while the standard
was not applicable. Others recommended that EPA designate as
nonattainment all areas that have current violations of the 1-hour
standard.
Specifically, some commenters request that EPA now designate as
attainment areas that were designated as nonattainment and that have
never been approved for redesignation in accordance with the criteria
in section 107(d)(3)(E). Thus, the commenters request EPA to rely on
its revocation action as a justification for avoiding those
requirements.
Response: As provided in section III.A, above, in today's action
EPA is only reversing its earlier determination that the 1-hour
standard no longer applies in these and other areas. Therefore, EPA is
not considering current air quality data in establishing designations
under this action as EPA would do when establishing initial
designations for areas under section 107(d)(1) or redesignating areas
under section 107(d)(3). In promulgating 40 CFR 50.9(b), EPA determined
that the designations and classifications were linked to the
applicability of the 1-hour standard. On that basis, in applying
section 50.9(b), EPA removed not just the applicability of the 1-hour
standard, but also the associated designation and classification for
the 1-hour standard. Because EPA is rescinding its prior findings
concerning the applicability of the 1-hour standard, the designations
and classifications that accompanied that standard at the time of
revocation come back into place with the standard.
The EPA disagrees with the commenters as a matter of law and
policy. It is clear from the CAA, as amended in 1990, that Congress
intended areas to meet specific criteria for redesignation with respect
to an existing, applicable NAAQS. As discussed above in section III.A &
B, EPA believes it was appropriate to transition from the 1-hour ozone
standard to the 8-hour ozone NAAQS by requiring only that areas attain
the 1-hour standard--one of the five criteria \21\ for redesignation.
However, EPA believes it would circumvent Congressional intent to
reinstate the 1-hour standard because of the uncertainty surrounding
the 8-hour standard and permit areas effectively to be redesignated
from nonattainment to attainment without meeting the other four
redesignation criteria. The EPA does not believe that it can rely on
its rule determining the 1-hour standard no longer applies, the basis
for which has been undermined by the ATA decision, as support for
sidestepping the redesignation criteria.
---------------------------------------------------------------------------

\21\ Section 107(d)(3)(E) provides that EPA may not redesignate
an area from nonattainment to attainment unless EPA: (1) determines
that the area has attained the relevant NAAQS; (2) has fully
approved the area's SIP; (3) determines that the improvement in air
quality is due to permanent and enforceable reductions in emissions;
(4) has fully approved a maintenance plan for the area; and (5) has
determined that the State has met all of the applicable SIP planning
requirements.
---------------------------------------------------------------------------

Moreover, because EPA cannot be sure how long it will take to
resolve the issues surrounding the 8-hour standard, EPA believes that
it is important to ensure that areas will maintain the 1-hour standard.
The statutory redesignation criteria are designed to accomplish that
goal. Thus, EPA believes it is essential that they be met.
However, EPA believes that it is appropriate to provide additional
time to nonattainment areas with clean air quality data since
revocation in order to complete the redesignation process. Therefore,
EPA is taking final action today to delay the applicability date of the
final rule for up to 180 days for areas that were designated
nonattainment at the time of revocation and continue to have clean
data, in order to allow States to submit redesignation requests and EPA
time to act on them prior to the applicability date. These areas are
identified in Table 1. In the proposed action to reinstate the
standard, EPA recommended that areas begin to develop redesignation
requests (or revise, as necessary, any existing requests) so that EPA
could move forward quickly to approve the requests upon reinstatement.
The EPA understands that some States are now ready, or close to being
ready, to submit these requests to EPA. If requests are submitted
within the next 2 months, EPA believes it can complete action on them
before this rule becomes applicable. The EPA will work with States to
ensure that review of redesignation requests occurs expeditiously. In
addition, if States are able to submit redesignation requests and EPA
is able to process such requests to the point of final action prior to
180 days from publication, the final action approving the redesignation
may provide that the applicability date of the reinstatement will be
the same date as the effective date of the redesignation approval, so
that the redesignations will occur simultaneously with the
reinstatement.
Once EPA approves a redesignation request, an area would be subject
to the requirements of the approved maintenance plans. Redesignation to
attainment does not relieve an area of its conformity obligations.
With respect to all of the areas previously designated
nonattainment which currently have clean air quality data, as listed in
Table 1, EPA concluded at the time of revocation that these areas had
clean air quality data. These findings remain applicable unless

[[Page 45192]]

more recent air quality data indicates that a violation has occurred.
The EPA intends to complete rulemaking prior to the applicability date
of this rule to determine the eligibility of these areas to use EPA's
May 10, 1995 clean data policy. (Reasonable Further Progress,
Attainment Demonstration, and Related Requirements for Ozone
Nonattainment Areas Meeting the Ozone National Ambient Air Quality
Standard, John S. Seitz).
The EPA acknowledges that reinstating the designations as they were
prior to revocation arguably may produce some inequities among areas;
however, these potential inequities are inherent in the redesignation
process set forth in section 107. As provided in section III.D, above,
Congress provided EPA with discretion in determining whether to
redesignate areas from attainment to nonattainment and specified
factors for EPA to consider. In comparison, Congress prohibited EPA
from redesignating an area from nonattainment to attainment unless EPA
determined that the area meets five specific criteria. In addition, any
redesignation must occur through notice-and-comment rulemaking. Thus,
at any point in time, an area can be attaining the standard, yet still
be designated nonattainment, or designated attainment and be violating
the standard, including the period while rulemaking to effect a
redesignation is proceeding.\22\
---------------------------------------------------------------------------

\22\ One court, in an unpublished opinion, upheld EPA's
interpretation of the redesignation provisions of the CAA that an
area must attain the standard and remain in attainment during the
time that a redesignation request is pending in order to qualify for
redesignation. Commonwealth of Kentucky, et al. v. US EPA, No. 96-
4274 (6th Cir. Sept. 2, 1998).
---------------------------------------------------------------------------

Areas where EPA is today reinstating the applicability of the 1-
hour standard will be placed back into the same position they were in
prior to revocation. The EPA does not believe that this creates any
additional inequities for these areas. It is true that EPA had
previously relieved areas of the obligation to develop a maintenance
plan for the 1-hour standard since they were to begin implementing the
8-hour standard. However, since it is now uncertain when areas will be
required to implement the 8-hour standard, EPA does not believe it is
inequitable to require these areas, as any other area, to develop
maintenance plans prior to redesignating them to attainment.
Comment: A few commenters made requests that specific types of
areas not be designated nonattainment. One commenter suggested that EPA
should designate as attainment areas that were previously designated
marginal or rural transport areas and that are clean without requiring
redesignation. A few commenters suggested that EPA not penalize areas
with violations where the cause of the violations is clearly one of
transport and dislike the ``unfair'' label of nonattainment.
Response: For the reasons provided above, EPA does not see a legal
avenue for changing the designation of marginal or rural nonattainment
areas or areas affected by transport based solely on the reinstatement
of the standard. Nor do the commenters identify a legal mechanism for
treating these areas differently from other nonattainment areas with
clean data.\23\ Some commenters set forth conflicting arguments,
arguing that EPA should generally establish the designations that were
in place at the time of the revocation while simultaneously claiming
that certain types of areas should be designated based on current air
quality. The EPA does not see how it can reconcile these conflicting
positions. As provided above, EPA believes the only proper
interpretation of this reinstatement action is that prior actions are
reversed such that prior designations are put back into place. The EPA
will consider current air quality data in determining whether to
redesignate areas under section 107(d)(3).
---------------------------------------------------------------------------

\23\ One commenter suggests that we could do so as we did in
revoking the standard. However, that was not a case of simply
telling areas that they did not need to submit maintenance plans
notwithstanding their nonattainment designation. It was a case of
telling areas that they were no longer subject to any obligations
with respect to the 1-hour standard based on expected implementation
of the 8-hour standard, which would no longer be the case for
marginal or rural nonattainment areas or areas affected by transport
where the 1-hour standard is reinstated.
---------------------------------------------------------------------------

In addition, EPA already has provided relief to areas subject to
transport in a number of ways. Such areas may continue to take
advantage of appropriate EPA policy relating to areas affected by
transport.\24\ In addition, EPA has issued final rules requiring States
or sources to address transported NO_X and ozone in
accordance with section 110(a)(2)(D) of the CAA. Final NO_X
SIP Call Rule (63 FR 57356, October 27, 1998); Final Rule on Section
126 Petitions (64 FR 28250, May 25, 1999). Areas affected by transport
will benefit from these rules.
---------------------------------------------------------------------------

\24\ E.g.,``Extension of Attainment Dates for Downwind Transport
Areas,'' from Richard Wilson, Acting Assistant Administrator for Air
and Radiation, dated July 16, 1998, published at 64 FR 14441, March
25, 1999.
---------------------------------------------------------------------------

Comment: Some commenters were concerned about redesignation
requests and maintenance plans submitted prior to the time that EPA
determined that the 1-hour standard no longer applied. These commenters
thought that it would be unfair for EPA to require the areas to update
the maintenance plan to provide maintenance for 10 years from the time
of EPA's approval.
Response: The EPA appreciates the concerns of those few areas that
may have had pending redesignation requests that demonstrate continued
maintenance for some period shorter than 10 years from the time of
EPA's final action, due to the passage of time. In such areas, EPA will
work with those States and respective transportation agencies to
develop technically sound future budgets. Such future emissions
projections will consider growth for existing and future sources,
forecasting for vehicle miles traveled, other federally mandated
programs, particularly the more recent mobile fuels rules and other
applicable measures; the resulting budgets will undergo normal public
process review. The EPA will work with the affected areas on an
individual basis to determine the extent to which additional
maintenance demonstrations may be needed to support redesignation, and
will take appropriate final action on maintenance demonstrations in
connection with future action on pending redesignation requests.

G. Areas Designated Nonattainment With Violations Since Revocation

For areas designated nonattainment with violations since the
standard was revoked in those areas, EPA proposed that the
nonattainment designation would again apply and that the area would be
subject to the subpart 2 requirements once the reinstatement became
effective. The EPA proposed that these areas have a reasonable time to
meet the applicable planning requirements and that EPA would work with
each area to establish a submittal schedule. This only applies to one
area, Sussex Co., DE., based on 1996-98 data.
Comment: Most commenters did not raise separate issues with respect
to this specific group of areas. A few commenters specifically noted
that they supported reinstating the nonattainment designation for these
areas. Some commenters requested EPA to be clear about what the
implications are for reinstatement. In particular, they were concerned
about what planning and control requirements might apply and what would
be the timing.
Response: The planning and control requirements that will apply for
this area are the applicable planning and control requirements in
subpart 2 of the CAA. The EPA will work with Delaware to determine
appropriate SIP submittal

[[Page 45193]]

deadlines for any programs that have not yet been submitted.

H. Effective Date and Applicability Dates of Reinstatement

The EPA proposed to delay the effective date \25\ of any final
reinstatement notice by 90 days in order to provide areas with a short
period of time in which to prepare for the applicability of conformity
and new source requirements which will be triggered by the
reinstatement of the 1-hour standard and the designations for that
standard. In the final rule, EPA has retained the 90-day effective
date. However, for areas that were designated as nonattainment at the
time EPA revoked the 1-hour standard and that have continued to have
clean air quality since revocation, EPA is establishing an
applicability date for the reinstatement of up to 180 days after
publication of the final rule. These areas are listed in Table 1.
During this period, EPA will review any pending redesignation requests
or requests that may be submitted shortly after this final action is
published. If EPA is able to complete final rulemaking action to
redesignate an area to attainment during that 180-day period, EPA will
provide in the final redesignation rule that the area will be
designated attainment as of the applicability date of this rule, so
that by the time reinstatement is applicable for any such area, the
area will receive an attainment designation. In addition, if States are
able to submit redesignation requests and EPA is able to process such
requests to the point of final action prior to 180 days from
publication, the final action approving the redesignation may provide
that the applicability date of the reinstatement will be the same date
as the effective date of the redesignation approval, so that the
redesignations will occur simultaneously with the reinstatement. As
mentioned before, the 45 areas listed in Table 1 may elect to submit
redesignation requests.
---------------------------------------------------------------------------

\25\ See footnote 9, above.
---------------------------------------------------------------------------

Comment: Some commenters disagreed with the proposed 90-day delay
in effectiveness, claiming it would be too short a time frame to
complete conformity determinations on transportation improvement plans
(TIPs) or for redesignation to occur. One commenter suggested a 180-day
delay in the effective date. Other commenters believed that the final
action reinstating the standard and the associated designation should
be effective immediately. Finally, some commenters supported EPA's
proposal to make the reinstatement and the associated designations
effective 90 days after publication.
Response: With respect to the effective date of the rule, EPA has
determined, based upon the comments submitted, that a 90-day delayed
effective date is an appropriate time period for most areas. The time
from the October 25th proposal to the end of the 90-day period is
approximately 10 months. The EPA believes this period is sufficient for
States to complete air quality analyses for conformity determinations
on transportation plans prior to the effective date of the final rule.
Thus, areas should not experience any delays in transportation
projects. At the same time, reinstatement of the standard with the
associated public health and welfare protections will not be
significantly delayed. The EPA does not anticipate that areas will
attempt to complete transportation activities inconsistent with
reinstatement of the 1-hour standard prior to the effective date, but
rather that they will use the delay to ensure they are ready to meet
the applicable requirements when the reinstatement becomes effective.
Thus, EPA concludes that a 90-day delayed effective date is a
reasonable accommodation between the competing interests of public
health protection and transportation planning for most areas.
The EPA agrees with commenters to the extent it concludes that up
to a 180-day delay in the applicability of this rule is appropriate for
areas that were designated nonattainment prior to revocation but that
currently have clean air quality data sufficient to support a
redesignation to attainment. Since these areas have continued to have
clean air since revocation, EPA believes it is appropriate to provide
up to an additional 90-day delay in the applicability of the rule to
allow these areas time to quickly complete and submit redesignation
requests and for EPA to act on submitted requests. Where EPA approves
such requests on or before the applicability date of this rule, the
area would be designated attainment at the time the reinstatement of
the 1-hour standard becomes applicable. The EPA notes again that if EPA
is taking final action to approve a redesignation prior to 180 days
from publication of this rule, the final action approving the
redesignation may provide that the applicability date of the
reinstatement will be the same date as the effective date of the
redesignation approval, so that the redesignations will occur
simultaneously with the reinstatement. Where EPA does not approve a
redesignation request or one is not submitted, the area will receive
the nonattainment designation which applied to the area prior to
revocation upon the applicability date of this rule.
The EPA notes that all of these areas will again be subject to
conformity upon the applicability date of the reinstatement of the 1-
hour standard and associated designations, since conformity applies to
both nonattainment and maintenance areas. As indicated above, EPA
anticipates that areas will use the delay to complete modeling efforts
and the consultation process so that they can have a conforming plan
and TIP in place by the applicability date.

I. Sanction and FIP Clocks

The EPA's proposed rule provided that any sanctions and FIP clocks
that were running at the time of the revocation should restart at the
point that they left off. In other words, if there were 6 months
remaining in the 2-year period for promulgation of a FIP, those
remaining 6 months would start to run for that area on the
applicability date of this action. The EPA is retaining this approach
in the final rule.
Comment: Some commenters stated that areas should not be subject to
any penalties or sanctions. Another commenter requested that EPA impose
sanctions immediately not only for those areas for which a clock was
running but also for those areas which may not have submitted a
required SIP but for which EPA never made a finding that started
sanctions and FIP clocks. This commenter suggested that sanctions
should be imposed no later than 90 days after the effective date of the
reinstatement for all such areas. In contrast, a number of commenters
supported EPA's approach. These commenters generally contended that
treating the clocks as if they continued to run during the time when
the standard did not apply would be considered enforcing the standard
when it was not in effect. One commenter seemed to support starting the
clock where it left off at the time of the revocation, but noted that
sanction clocks with time remaining should not allow States to delay
progress. The commenter states that areas violating the 1-hour standard
or contributing to violations in other areas must move forward ``as
expeditiously as practicable.''
Response: The EPA believes that the most equitable approach is to
restart clocks for sanctions or FIPs where they left off at the time of
the revocation. Because States and sources relied on EPA's final rule
determining that the standard no longer applied, States were not
affirmatively moving forward with

[[Page 45194]]

1-hour SIPs. \26\ Thus, EPA believes that it would be unfair to States
and affected sources to treat those clocks as if they continued to run
during the time that the 1-hour standard no longer applied.
---------------------------------------------------------------------------

\26\ One commenter suggests that EPA's actions revoking the 1-
hour standard and related designations were not legally valid at the
time they were taken. Thus, this commenter claims, that rule cannot
support a further delay in sanctions or FIPs. The EPA disagrees. The
EPA revoked the standard in full compliance with its regulation, 40
CFR 50.9(b), which was not challenged at the time it was
promulgated.
---------------------------------------------------------------------------

Similarly, EPA does not believe that it has authority, nor would it
be appropriate, to begin these clocks over again upon reinstatement or
to treat these clocks as no longer in effect. The FIP and sanctions
obligations under sections 110 and 179 of the CAA were previously
triggered for a State's failure to make a complete SIP submission or an
approvable submission as required under the CAA. By today's action,
areas will once again be subject to the same requirements to make
submissions. There is no basis for ignoring or discharging the State's
obligation with respect to these submissions. Moreover, EPA agrees that
sanctions clocks should not be treated by States as a ``grace period''
that allows deferral of compliance dates. Where a sanctions clock is in
place, States should submit plans to stop the clock as expeditiously as
practicable and should not delay submission until the last minute
before sanctions are put into place.
Because EPA is taking action to put areas back in the place they
were in prior to the revocation, the most appropriate course of action
is to restart these clocks where they left off. Therefore, upon the
applicability date of today's action, any sanctions or FIP clocks that
were running based on a State's default for a required submission will
restart at the point it was on the effective date of the revocation.
States should work to submit SIPs as expeditiously as practicable. Any
questions regarding the status of a sanction or FIP clock for a
specific area should be directed to the appropriate EPA Regional
Office. Finally EPA has no authority to impose sanctions where EPA has
not made appropriate findings to trigger clocks under section 179.

J. Conformity

The EPA proposed that conformity would apply upon the effective
date of the rule to all areas again designated nonattainment. The EPA
noted that these areas would need to have a conforming transportation
plan and program in place by the effective date of the rule in order to
fund new transportation projects after that date. The EPA also noted
that conformity has continued to apply to all attainment areas with
maintenance plans even after revocation, and that conformity does not
apply at all to attainment areas without maintenance plans. Upon the
applicability date \27\ of this final action, conformity will apply to
all designated nonattainment and maintenance areas as proposed.
---------------------------------------------------------------------------

\27\ See footnote 9 and section H. above for explanation of
terms ``effective date'' and ``applicability date.''
---------------------------------------------------------------------------

Several commenters expressed concerns about the conformity
requirements that apply to nonattainment and maintenance areas and the
timing of conformity determinations. The specific comments and
responses follow.
Comment: The transportation conformity rule requires conformity to
be determined at least every 3 years. Commenters requested that we not
consider the 3-year clock to have been running in nonattainment areas
where the 1-hour ozone standard was revoked and conformity did not
apply.
Response: We agree that in ozone nonattainment areas where the
ozone standard was revoked and conformity stopped applying, any of the
3-year or 18-month clocks (described in 40 CFR 93.104 \28\) that were
running at the time of the revocation were stayed on the effective date
of the revocation. On the applicability date of this final rule, those
clocks will pick up again at the point where they left off.
---------------------------------------------------------------------------

\28\ The EPA's conformity regulations require States to
redetermine conformity for all transportation plans and programs
every 3 years. 40 CFR 93.104(b)(3) and (c)(3). The regulations also
require a conformity determination within 18 months of various SIP
submittal and approval actions. 40 CFR 93.104(e).
---------------------------------------------------------------------------

In practice, this means that if an ozone nonattainment area had a
conforming TIP at the time of the revocation and did not amend the plan
and TIP with respect to any non-exempt projects during the time
conformity did not apply, the transportation plan and TIP would
continue to be considered ``currently conforming'' even if more than 3
years have elapsed since the conformity determination.
The area would need to document that the transportation plan and
TIP have not changed since the time of the last conformity
determination in a manner that would have required a new conformity
determination. The area should also clearly identify how much time
remains on the 3-year clock and any 18-month clock that was triggered
by 40 CFR 93.104.
We are not concerned that the temporary halt of the clocks in 40
CFR 93.104 will result in transportation plans and TIPs that are
relying on very old conformity determinations. The Department of
Transportation (DOT) requires transportation plans and TIPs to be
regularly updated, and those planning clocks have been running
regardless of the revocation. The plan and TIP updates require
conformity determinations. Therefore, any plans and TIPs with
conformity determinations from before the revocation will be updated
soon under DOT's planning regulations.
For any plans and TIPs that were amended with respect to non-exempt
projects while the ozone standard was revoked, a new conformity
determination will be required by the time the reinstatement is
applicable. This is because these plans and TIPs will generally not yet
have been found to conform and would have to be found to conform by the
applicability date of reinstatement to enable projects to proceed.
Comment: One commenter asked what process is required for areas
that voluntarily complied with conformity requirements while the ozone
standard was revoked.
Response: If an area amended its plan and TIP while the ozone
standard was revoked, but the amendment(s) fully met the requirements
of the conformity rule (including public participation), the area would
simply need to document this and receive confirmation from the Federal
agencies that the transportation plan and TIP are considered
``currently conforming.''
Comment: Some commenters were concerned that they do not have
enough time to determine conformity before the reinstatement is
applicable, and/or that it is burdensome to determine conformity of the
current plan and TIP when they are updating the plan and TIP very soon
(which will also require a conformity determination).
Response: We understand that this final rule changes the usual
cycle for determining conformity. Counting from the time we proposed to
reinstate the standard, areas will have had at least ten months to
complete the conformity process prior to the applicability date of this
rule. We believe this is a reasonable time frame, although we recognize
that the timing for this conformity process may not be optimal for some
areas.
We must balance the desire for additional time for transportation
planning with the need to protect public health with the 1-hour ozone
standard and statutory requirement for conformity determinations. In
some areas, transportation investments were planned or approved during
the

[[Page 45195]]

revocation without a demonstration that they will not interfere with
attainment of the one-hour ozone standard. It is important to conduct
such a demonstration expeditiously so that areas do not irreversibly
commit to transportation projects that are inconsistent with healthy
air.
Comment: One commenter stated that the proposed criteria for
conformity are not consistent with the March 2, 1999 decision of the
Court of Appeals in EDF v. EPA, 167 F.3d 641,650 (1999) on conformity.
The commenter argues that the court required EPA to develop a test to
ensure conformity consistent with CAA 176(c)(1) and that this must be
done now for all areas where the standard is to be reinstated.
Response: Conformity determinations should comply with the CAA, as
recently interpreted in the EPA and DOT guidance issued in response to
the March 1999 court decision (EPA's May 14, 1999 guidance entitled,
``Conformity Guidance on Implementation of March 2, 1999 Conformity
Court Decision'' and DOT's June 18, 1999 guidance entitled,
``Additional Supplemental Guidance for the Implementation of the
Circuit Court Decision Affecting Transportation Conformity''). We
believe that these guidance documents are consistent with the court's
decision and that conformity determinations performed consistent with
the guidance are legally sound. We will be formally proposing to amend
the transportation conformity rule to incorporate this guidance,
pursuant to CAA section 176(c)(4)(A).
The commenter appears to believe that the court decision required
EPA to develop additional criteria to satisfy the obligations of
section 176(c)(1) of the CAA, which require Federal agencies and
Metropolitan Planning Organizations (MPOs) to determine that Federal
actions will not interfere with timely attainment, in situations where
they are determining conformity to budgets in submitted SIPs. However,
EPA believes that the court in actuality merely remanded EPA's rules,
stating that ``where EPA fails to determine the adequacy of motor
vehicle emissions budgets in a SIP revision within 45 days of
submission, * * * there is no reason to believe that transportation
plans and programs conforming to the submitted budgets will [meet the
statutory tests in section 176(c)(1)(B)].'' The EPA interprets this
aspect of the decision to require it to revise its regulations to
mandate that EPA make affirmative findings of adequacy on all submitted
SIPs before they can be used for conformity purposes. The procedure for
doing this is outlined in the guidance mentioned above. The EPA does
not believe the court addressed any deficiency in EPA's regulations
governing conformity determinations in situations where EPA has made a
positive finding of adequacy. The EPA concludes that the court only
remanded the aspect of EPA's regulations at 40 CFR 93.118(e)(1) which
allows use of submitted SIPs which EPA has not yet found adequate,
since it did not remand either EPA's regulations at 40 CFR 93.118(e)(4)
establishing criteria for finding budgets adequate or 93.118(e)(6)
requiring additional findings by Federal agencies and MPOs where
conformity determinations are made to submitted SIPs. Therefore, EPA
believes that conformity determinations consistent with these two
provisions and our guidance on finding budgets adequate fully satisfy
the requirements of the CAA and we intend to revise our regulations
consistent with that guidance. Of course, commenters will have the
opportunity to comment on those regulatory changes when they are
proposed and to raise any issues associated with EPA's interpretation
of the court opinion at that time. The EPA does not believe that such
comments are directly relevant to this rulemaking and, therefore, is
not making any changes to the conformity rules in connection with this
final action.
Comment: One commenter argued that conformity to adequate SIP
budgets in nonattainment areas, should continue even after any future
revocations until new adequate budgets are submitted for the 8-hour
standard.
Response: Section 176(c)(5) of the CAA clearly provides that
conformity requirements only apply in nonattainment areas and areas
that had been nonattainment and were subsequently redesignated to
attainment and are subject to the requirement to develop a maintenance
plan. Since nonattainment areas where EPA may in the future revoke the
1-hour standard once an 8-hour standard becomes fully enforceable will
no longer be designated nonattainment or subject to the requirement to
submit a maintenance plan, for the reasons explained above, EPA
concludes that it would have no authority under section 176(c) to
require conformity to previously submitted 1-hour budgets after any
future revocations.

K. New Source Review

In the October 25th proposal, EPA solicited comment on what NSR
requirements should apply in areas that had, subsequent to our findings
that the 1-hour standard no longer applied, revoked their nonattainment
NSR programs. Specifically, EPA asked whether 40 CFR part 51, Appendix
S should be followed or the higher offset/major source thresholds in
subpart 2 of the CAA should be followed in nonattainment areas where
the SIP lacks the applicable nonattainment NSR provisions.
Comment: Several commenters wanted flexibility in applying NSR
requirements. There was a mixed reaction for and against using 40 CFR
appendix S. As to the question of whether States must issue permits
consistent with the additional requirements of subpart 2, even in the
absence of an approved NSR SIP, one commenter stated that it was not
supportive of any EPA action that would cause enforcement of NSR on
facilities that were or are under no legal obligation to comply with
NSR requirements. Another commenter urged EPA to require sources to
comply with subpart 2 notwithstanding the lack of an approved SIP,
citing a 1992 EPA policy memorandum as support.
Response: The EPA solicited comment on how to address areas that
were designated nonattainment prior to the findings that the 1-hour
standard no longer applied and which, since revocation, had amended
their SIPs to remove the applicable nonattainment NSR provisions. The
EPA has determined that it is unnecessary to resolve this question in
this rulemaking, as we have determined that no area has amended its SIP
since the nonattainment designations were removed. Thus, the applicable
SIPs in each area will specify the nonattainment NSR responsibilities
of sources in the area, without any action by EPA.
Comment: Sources that have applied for PSD permits during the
period that the 1-hour ozone standard did not apply should not have to
seek part D NSR permits. Allowing sources with complete applications to
avoid more stringent requirements is consistent with EPA policy. Such
an approach is also consistent with how EPA acted following the
adoption of PM10 as the indicator for particulate matter in
1987. At that time, EPA allowed sources with complete PSD permit
applications that did not account for the sources' PM10
emissions to be grandfathered.
Response: Whether or not sources must apply for part D
nonattainment NSR permits upon reinstatement of the 1-hour standard
will be determined by the applicable SIP. The EPA expects that most, if
not all, SIPs already specify that sources in designated nonattainment
areas must obtain part D permits. Accordingly, some sources may have to
revise their permit applications. Even if EPA were to agree that it
would

[[Page 45196]]

be appropriate to allow such sources to obtain PSD permits rather than
nonattainment NSR permits, EPA cannot override by policy the legal
requirements of a more stringent applicable SIP. Regarding the
PM10 transition policy to which the commenter refers, that
policy is inapplicable in the present situation because it did not deal
with the kind of situation at issue currently--where areas will be
switching from one designation status (no designation) to
nonattainment. The EPA had concluded in that rulemaking that part D,
including part D NSR, did not apply at all to the revised particulate
matter NAAQS, so there was not a question about which NSR program would
apply. See 52 FR 24672, 24678 (July 1, 1987).

L. Miscellaneous Comments

Comment: One commenter noted that EPA should notify the public of
the terms of a stipulation agreement reached between EPA and the
Environmental Defense Fund (EDF) wherein EPA agreed to accept comment
on certain items in the reinstatement notice.
Response: In its notice reopening the comment period on Dec. 8,
1999, EPA explicitly provided that it would accept comment on the list
of issues recited in the stipulation filed in EDF v. EPA, (D.C. Cir.,
No. 98-1363). (64 FR 68659, December 8, 1999).
Comment: Several commenters supported applying the reinstatement
retroactively, such that areas would be treated as if the standard and
the associated designations have always applied. Some were not
supportive of retroactively applying the 1-hour standard during the
time it was revoked. With respect to conformity determinations, one
commenter believed that we shouldn't allow ``grandfathering'' of
projects if prior conformity determinations would have lapsed during
the time the standard was not applicable; they believe that in cases
where it is not possible to reverse actions, then they must be subject
to some mitigation procedure to address actions that allowed for
emission increases during that time.
Response: The EPA concludes that it is not appropriate to apply the
reinstatement of the 1-hour standard retroactively. The EPA believes
that it had full authority to revoke the 1-hour standard initially, and
that its actions were legal and proper at the time they were taken.
Although EPA now concludes that it should rescind those actions due to
changed circumstances, it would be unfair to areas that had relied on
the initial revocations (and to sources located in those areas) to
apply the rescissions retroactively. Many areas took actions during the
period of time that the 1-hour standard was not applicable that
properly relied on the inapplicability of that standard. Rules altering
prior actions are generally applied only prospectively and are applied
retroactively only in unusual cases, for instance where an agency did
not have the authority to take a prior action initially. Courts
generally view retroactive application of administrative rules with
disfavor unless such application is specifically sanctioned by statute.
Bowen v. Georgetown University Hospital, 488 U.S. 204 (1988). The CAA
does not specifically provide for retroactive application of
regulations under title I. Therefore, although EPA might have authority
to apply the reinstatement retroactively if a court determined that
EPA's action in revoking the standard was illegal, EPA does not believe
it is appropriate to do so here where EPA believes it was fully
authorized to revoke the standard at the time it took such action.
The EPA also concludes for similar reasons that it would not be
appropriate for conformity purposes to treat conformity determinations
as having lapsed during the time that the 1-hour standard was not
applicable to an area. Because the 1-hour standard no longer applied
during that period, areas were not on notice that conformity
determinations were to lapse. It would be equally unfair to areas to
achieve a similar result by denying grandfathering status under the
conformity rules to any project approved during a time period when
conformity status would have lapsed if the standard had been
applicable. The EPA concludes that areas should be allowed to continue
to rely on the inapplicability of the 1-hour standard during the period
between revocation and reinstatement because EPA had the authority to
revoke the standard and properly revoked it initially.\29\
---------------------------------------------------------------------------

\29\ One commenter notes that some areas should have been on
notice that revocations were questionable since one action
promulgating revocations was not published in the Federal Register
until after May 14, 1999, the date of the adverse court decision in
ATA (64 FR 30911, June 9, 1999). However, that final action of the
Administrator was taken (final rulemaking notice signed by the
Administrator) on May 12, 1999, prior to the court decision; only
publication occurred after the decision. The EPA did not take any
further actions revoking the 1-hour standard in any areas after the
date of the ATA decision.
---------------------------------------------------------------------------

For these same reasons, EPA concludes that where highway projects
or new sources have already been constructed, areas should not be
required to immediately implement mitigation measures to remedy any
resulting emissions increases. Areas will effectively have to provide
for mitigation in future transportation and air quality planning once
the 1-hour standard is reinstated. All future air quality planning for
attainment and reasonable further progress as well as conformity
determinations will have to account for emissions from such activities.
However, EPA believes that it would be inequitable to require areas to
immediately institute specific mitigation measures to account for any
emissions increases that may have occurred during the time that the
standard was not applicable to an area.
Comment: Several commenters took the opportunity to comment on the
8-hour ozone standard. Many requested that designations for the 8-hour
standard not be made until legal issues are resolved. Many asked for
guidance to States on meeting the 8-hour standard in the interim.
Several called upon the Agency to revoke the 8-hour standard.
Response: The numerous comments concerning the 8-hour standard,
including those relating to designations under the 8-hour standard,
guidance on implementation of the 8-hour standard, and requests for
revocation of the 8-hour standard, are not relevant to this rulemaking
on reinstatement of the 1-hour standard. The EPA will address issues
relating to the 8-hour standard in separate rulemaking actions or
guidance documents.
Comment: One commenter suggested that we explore the Flexible
Attainment Region (FAR) approach to provide flexibility to States in
determining measures to prevent air quality deterioration and to
improve air quality. The commenter suggests that EPA give these
``voluntary programs'' time to work before triggering nonattainment
designations. The same commenter also requests EPA to extend to ozone
areas the flexibility provided in EPA's draft guidance for PM-10
nonattaiment areas with respect to limited maintenance plans.
Response: The EPA has used the FAR approach in the past with
respect to areas designated attainment but that are violating the ozone
standard. As provided above, EPA has some discretion in deciding
whether to redesignate such areas as nonattainment. In exercising that
discretion, EPA may consider ``planning and control'' activities. Thus,
in the past, EPA has not moved forward to redesignate to nonattainment
attainment areas that were voluntarily adopting and implementing
measures to address violations. The EPA plans to continue this approach
for such areas as explained in sections III.D and E, above.

[[Page 45197]]

However, as also explained above, EPA does not believe it has the
authority to reinstate the standard and not designate as nonattainment
those areas designated as nonattainment at the time of the revocation
action. These areas would be subject to the specific planning
requirements that Congress provided under the CAA until they qualify
for redesignation. The EPA cannot ignore the statutory mandate in favor
of more flexible means of achieving attainment that could be allowed
under the FAR approach. Therefore, designated nonattainment areas
cannot use a FAR because the statutory requirements apply.
With respect to the comment regarding EPA's draft limited
maintenance plan guidance for PM-10 areas seeking redesignation from
nonattainment to attainment, EPA notes that it has an existing limited
maintenance plan policy for ozone (``Limited Maintenance Plan Option
for Nonclassifiable Ozone Nonattainment Areas,'' November 16, 1994,
Sally Shaver) This policy provides some flexibility, e.g., no
requirement to project emissions out into the future, no need for
maintenance demonstration since met by meeting the NAAQS, etc. The
commenter appears not to recognize that such a policy exists and does
not further explain what flexibilities in the draft PM-10 policy they
would like extended to ozone areas.

IV. What Administrative Requirements Are Considered in Today's
Final Rule?

A. Executive Order 12866: Regulatory Impact Analysis

Under Executive Order 12866, [58 FR 51,735 (October 4, 1993)] the
Agency must determine whether the regulatory action is ``significant''
and therefore subject to Office of Management and Budget (OMB) review
and the requirements of the Executive Order. The Order defines
``significant regulatory action'' as one that is likely to result in a
rule that may:
(1) Have an annual effect on the economy of $100 million or more or
adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or tribal governments or
communities;
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budgetary impact of entitlements, grants,
user fees, or loan programs or the rights and obligations of recipients
thereof; or
(4) Raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
It has been determined that this final rule is a ``significant
regulatory action'' under the terms of Executive Order 12866;
therefore, it was submitted to OMB for their review.

B. Regulatory Flexibility Act

Under the Regulatory Flexibility Act (RFA), 5 U.S.C. 601 et seq.,
EPA must prepare a regulatory flexibility analysis assessing the impact
of any proposed or final rule on small entities (5 U.S.C. 603 and 604),
unless EPA certifies that the rule will not have a significant impact
on a substantial number of small entities. Small entities include small
businesses, small not-for-profit enterprises, and government entities
with jurisdiction over populations of less than 50,000. The EPA is
certifying that this final rule will not have a significant impact on a
substantial number of small entities because the determination that the
1-hour standard again applies does not itself directly impose any new
requirements on small entities. See Mid-Tex Electric Cooperative, Inc.
v. FERC, 773 F.2d 327 (D.C. Cir. 1985) (agency's certification need
only consider the rule's impact on entities subject to the requirements
of the rule). Instead, this rule merely establishes that the 1-hour
standard again applies in certain areas. For the most part, any
requirements applicable to small entities that may indirectly apply as
a result of this action would be imposed independently by the State
under its SIP, not by EPA through this action. Moreover, to the extent
this rule would automatically trigger the applicability of certain SIP
requirements to small entities (e.g., NSR), this rule cannot itself be
tailored to address small entities that would be subject to those
requirements.
One requirement that may apply immediately upon this action to all
designated nonattainment areas is the requirement under CAA section
176(c) and associated regulations to demonstrate conformity of Federal
actions to SIPs. However, those rules only apply directly to Federal
agencies and MPOs, which by definition are designated only for
metropolitan areas with a population of at least 50,000 and thus do not
meet the definition of small entities under the RFA. Therefore, I
certify that this action will not have a significant impact on a
substantial number of small entities within the meaning of those terms
for RFA purposes.

C. Unfunded Mandates

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for Federal agencies to assess the
effects of their regulatory actions on State, local, and tribal
governments, and the private sector. Under section 202 of UMRA, EPA
generally must prepare a written statement, including a cost-benefit
analysis, for proposed and final rules with ``Federal mandates'' that
may result in expenditures by State, local, and tribal governments, in
the aggregate, or by the private sector, of $100 million or more in any
one year. Before promulgating an EPA rule for which a written statement
is needed, section 205 of UMRA generally requires EPA to identify and
consider a reasonable number of regulatory alternatives and adopt the
least costly, most cost-effective or least burdensome alternative that
achieves the objectives of the rule. The provisions of section 205 do
not apply when they are inconsistent with applicable law. Moreover,
section 205 allows EPA to adopt an alternative other than the least
costly, most cost-effective or least burdensome alternative if the
Administrator publishes with the final rule an explanation why that
alternative was not adopted. Before EPA establishes any regulatory
requirements that may significantly or uniquely affect small
governments, including tribal governments, it mush have developed under
section 203 of UMRA a small government agency plan. The plan must
provide for notifying potentially affected small governments, enabling
officials of affected small governments to have meaningful and timely
input in the development of EPA regulatory proposals with significant
Federal intergovernmental mandates, and informing, educating, and
advising small governments on compliance with the regulatory
requirements.
Today's final action does not include a Federal mandate within the
meaning of UMRA that may result in expenditures of $100 million or more
in any one year by either State, local, or tribal governments in the
aggregate or to the private sector. This rule would reinstate the
applicability of the 1-hour ozone standard and alter the designation
status of areas. The consequences of this action may result in some
additional costs within the affected areas, but these costs would not
exceed $100 million per year in the aggregate.\30\ In view of recent
concerns about increased gas prices in

[[Page 45198]]

certain areas, we specifically note that this action will not impose
any requirements on gasoline and will not affect current gas prices.
---------------------------------------------------------------------------

\30\ See Docket A-99-22, III-B-04, ``Preliminary Assessment of
the Incremental Burden Associated with Reinstatement of the 1-Hour
Ozone Standard for UMRA, dated October 14, 1999.
---------------------------------------------------------------------------

One mandate that may apply as a consequence of this action to all
designated nonattainment areas is the requirement under CAA section
176(c) and associated regulations to demonstrate conformity of Federal
actions to SIPs. These rules apply to Federal agencies and MPOs making
conformity determinations. The EPA concludes that such conformity
determinations will not cost $100 million or more in the aggregate
annually.\31\
---------------------------------------------------------------------------

\31\ See footnote 30, above.
---------------------------------------------------------------------------

In addition, some areas with recent air quality violations will
have to take the additional steps specified in their maintenance plans
to limit emissions of air pollutants. These measures could, for
example, include revising the threshold for NSR, establishing
reasonable available control technology (RACT) level control for
additional sources, and establishing or enhancing inspection and
maintenance (I/M) programs within the area. These measures vary
substantially in terms of the expected emissions reductions and their
potential cost. Because the affected jurisdictions have some
flexibility to choose among these measures, it is difficult to estimate
the overall cost of these additional controls. The EPA believes that
the affected areas are already carrying out many of the other
obligations associated with this action. For example, most areas that
would have a nonattainment designation reinstated upon reinstatement of
the 1-hour standard already have NSR requirements under their existing
SIP programs. In addition, many of these areas are located in the
Northeast Ozone Transport Region and are already carrying out many of
the requirements associated with the reinstatement of the 1-hour
standard. Therefore, EPA believes that any new controls imposed as a
result of this action will not cost in the aggregate $100 million or
more annually. Thus, this Federal action will not impose mandates that
will require expenditures of $100 million or more in the aggregate in
any one year.

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

Executive Order 13045: ``Protection of Children from Environmental
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies
to any rule that: (1) is determined to be ``economically significant''
as defined under Executive Order 12866, and (2) concerns an
environmental health or safety risk that EPA has reason to believe may
have a disproportionate effect on children. If the regulatory action
meets both criteria, the Agency must evaluate the environmental health
or safety effects of the planned rule on children, and explain why the
planned regulation is preferable to other potentially effective and
reasonably feasible alternatives considered by the Agency.
The EPA interprets Executive Order 13045 as applying only to those
major regulatory actions that are based on health or safety risks, such
that the analysis required under section 5-501 of the Order has the
potential to influence the regulation. This final rule is not subject
to Executive Order 13045 because it does not meet either of the above
criteria. It is not economically significant as defined under Executive
Order 12866, and it implements a previously promulgated health or
safety-based Federal standard and does not itself involve decisions
that affect environmental health or safety risks.

E. Submission to Congress and the General Accounting Office

Under 5 U.S.C. 801(a)(1)(A), as added by the Small Business
Regulatory Enforcement Fairness Act of 1996, EPA submitted a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives and the Comptroller General of the
General Accounting Office prior to publication of the rule in today's
Federal Register. This rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).

F. Executive Order 13132: Federalism

Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.''
Under Section 6 of Executive Order 13132, EPA may not issue a
regulation that has federalism implications, that imposes substantial
direct compliance costs, and that is not required by statute, unless
the Federal government provides the funds necessary to pay the direct
compliance costs incurred by State and local governments, or EPA
consults with State and local officials early in the process of
developing the proposed regulation. The EPA also may not issue a
regulation that has federalism implications and that preempts State
law, unless the Agency consults with State and local officials early in
the process of developing the proposed regulation.
As indicated in the proposal, EPA does not believe that this final
rule has federalism implications within the meaning of the Executive
Order. EPA has reached this conclusion for several reasons. As
discussed above in connection with UMRA, this action will not impose
substantial direct compliance costs on the States nor will it alter the
relationship between the national government and the States, or the
distribution of power and responsibilities among the various levels of
government. As noted previously, this rule simply reinstates the
applicability of the 1-hour ozone standard and the associated air
quality designations for various areas that had applied prior to
revocation. These actions do not preempt any State authority or
otherwise affect State flexibility to comply with the Clean Air Act.
Although reinstatement will alter the number of areas within various
states that are designated under the 1-hour standard, it will not alter
the relationships that currently exist between the States and the
federal government with respect to areas designated under the 1-hour
standard. Thus, EPA concludes that the requirements of section 6 of the
Executive Order do not apply to this rule.
In the spirit of the Executive Order however, the Agency has
consulted extensively with representatives of State and local
governments, including elected officials. As EPA was developing the
proposal and again when EPA issued the proposal, we phoned elected
officials or their staff for many of the areas that could be affected
by the rule to notify them that EPA was considering reinstating the 1-
hour ozone standard and to solicit their advice and concerns. The EPA
also notified national organizations of state and local government
officials and made EPA staff available to discuss the proposed action
with the organization staff and their members. These organizations
included the U.S. Conference of Mayors (USCM), the National Conference
of Black Mayors, the National Governors Association, the National
Council of State Legislators, the National Association of Counties,
ECOS, STAPPA/ALAPCO, the National

[[Page 45199]]

Association of Local Government Environmental Professionals, and the
Ozone Transport Commission. For example, EPA's Assistant Administrator
for Air and Radiation held a conference call with the USCM Energy and
Environment Committee members when the proposal was announced. In
addition, EPA sent letters to the Governors and their environmental
commissioners to ensure that they were aware of the proposal and could
comment on it. It was in response to concerns raised by these contacts
that EPA proposed to delay the effective date of the reinstatement for
90 days so that areas would have adequate time to comply with any
requirements triggered by reinstatement. In addition, based on comments
received from States after publication of the proposal, EPA decided to
provide a 180-day delayed applicability date for areas that were
designated nonattainment but currently have clean air data. EPA also
notes that, while it received no adverse comments regarding the
statements in the proposal concerning the lack of federalism
implications of this rule, it received numerous comments on the rule
from state and local governments. EPA has responded fully to all
comments raised by the various State and local governments, as
explained above in the sections of this notice describing the comments
and EPA's response to them.

G. Executive Order 13084: Consultation and Coordination With Indian
Tribal Governments

Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute that significantly or uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by the tribal governments, or EPA consults with those
governments. If EPA complies by consulting, Executive Order 13084
requires EPA to provide to OMB, in a separately identified section of
the preamble to the rule, a description of the extent of EPA's prior
consultation with representatives of affected tribal governments, a
summary of the nature of their concerns, and a statement supporting the
need to issue the regulation. In addition, Executive Order 13084
requires EPA to develop an effective process permitting elected
officials and other representatives of Indian tribal governments ``to
provide meaningful and timely input in the development of regulatory
policies on matters that significantly or uniquely affect their
communities.''
Today's final rule does not significantly or uniquely affect the
communities of Indian tribal governments. This final action does not
involve or impose any requirements that directly affect Indian tribes.
Under EPA's tribal authority rule, tribes are not required to implement
CAA programs but, instead, have the opportunity to do so. Accordingly,
the requirements of section 3(b) of Executive Order 13084 do not apply
to this rule.

H. Paperwork Reduction Act

This final action does not contain any information collection
requirements which require OMB approval under the Paperwork Reduction
Act (44 U.S.C. 3501 et seq.).

I. Executive Order 12898: Environmental Justice

Under Executive Order 12898, each Federal agency must make
achieving environmental justice part of its mission by identifying and
addressing, as appropriate, disproportionately high and adverse human
health or environmental effects of its programs, policies, and
activities on minorities and low-income populations. Today's final
action to reinstate the applicability of the 1-hour standard in certain
areas does not have a disproportionate adverse affect on minorities and
low-income populations.

J. National Technology Transfer and Advancement Act

Section 12 of the National Technology Transfer and Advancement Act
(NTTAA) of 1995 requires Federal agencies to evaluate existing
technical standards when developing new regulations. To comply with
NTTAA, the EPA must consider and use ``voluntary consensus standards''
(VCS) if available and applicable when developing programs and policies
unless doing so would be inconsistent with applicable law or otherwise
impractical.
The EPA believes that VCS are inapplicable to this final action.
Today's final action does not require the public to perform activities
conducive to the use of VCS.

K. Rule Effective Date and Applicability Dates

The EPA finds that there is good cause for this final action to
become effective \32\ and applicable either 90 or 180 days after
publication, depending upon type of area, since this would afford areas
time to get programs, such as conformity SIPs or redesignation
requests, in place. The EPA believes these are reasonable periods of
time to accommodate the competing interests of efficient air quality
and transportation planning and prompt public health protection. The
EPA has general administrative authority under section 301(a) of the
CAA and 5 U.S.C. 553(d) to establish the effective date and
applicability dates of a rule provided any delay in effective date or
applicability dates is reasonable. ASG Industries v. Consumer Product
Safety Commission, 593 F.2d 1323, 1335 (D.C. Cir. 1979). A 90- or 180-
day delay in effective or applicability date for a rule where areas
will have to develop various SIP emission control programs by the
effective or applicability date of the rule is reasonable. See Small
Refiner Lead Phase-Down Task Force v. EPA, 705 F.2d 506 (D.C. Cir.
1983) (EPA's decision to grant an 8-month period between date of
promulgation and effective date was reasonable where regulated entities
needed time to implement controls). The longer time period for areas
that are not experiencing violations is reasonable because no
violations are occurring in these areas. Moreover, EPA will need
additional time to take final action to redesignate areas as attainment
after States submit their plans to EPA.

L. Petitions for Judicial Review

Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by September 18, 2000. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this rule for the purposes of judicial review nor does
it extend the time within which a petition for judicial review may be
filed, and shall not postpone the effectiveness of such rule or action.
This action may not be challenged later in proceedings to enforce its
requirements (see section 307(b)(2)).
