[CA-189-0078(a); FRL-6127-1]
Approval and Promulgation of State Implementation Plans and
Redesignation of the South Coast Air Basin in California to Attainment
for Nitrogen Dioxide
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking direct final action on attainment and
maintenance plans and a request submitted by the California Air
Resources Board (CARB) to redesignate the South Coast Air Basin (South
Coast) from nonattainment to attainment for the National Ambient Air
Quality Standards (NAAQS) for Nitrogen Dioxide (NO2). Under
the Clean Air Act (CAA), designations can be revised if sufficient data
are available to warrant such revisions. In this action, EPA is
approving the attainment and maintenance plans as revisions to the
California State Implementation Plan (SIP), and EPA is also approving
the State's request to redesignate the South Coast to attainment
because the plans and request meet the requirements set forth in the
CAA.
EPA is publishing this rule without prior proposal because the
Agency views this as a noncontroversial amendment and anticipates no
adverse comments. However, in the proposed rules section of this
Federal Register publication, EPA is publishing a separate document
that will serve as the proposal to approve the SIP revision and grant
the redesignation request should relevant adverse comments be filed.
DATES: This rule is effective September 22, 1998 unless the Agency
receives relevant adverse comments to the rulemaking by August 24,
1998. If adverse comment is received, EPA will publish a timely
withdrawal of the direct final rule in the Federal Register and inform
the public that the rule will not take effect.
ADDRESSES: Comments should be addressed to the EPA contact below. The
rulemaking docket for this notice may be inspected and copied at the
following location during normal business hours. A reasonable fee may
be charged for copying parts of the docket.

SUPPLEMENTARY INFORMATION:
I. Clean Air Act Requirements
Under section 109 of the CAA, EPA established primary and secondary
NAAQS for NO2 in 1971, and slightly revised the NAAQS in
1985.1 The level of both the primary and secondary NAAQS is
0.053 parts per million (ppm), or 100 micrograms per cubic meter,
annual arithmetic mean concentration. The standards are attained when
the annual arithmetic mean concentration in a calendar year is less
than or equal to 0.053 ppm, based upon hourly data that are at least
75% complete.2
---------------------------------------------------------------------------
\1\ See 34 FR 8186, April 30, 1971, and 50 FR 25544, June 19,
1985, codified at 40 CFR 50.11. Nitrogen dioxide is a light brown
gas that can irritate the lungs and lower resistance to respiratory
infections such as influenza. The principal sources of nitrogen
oxides are high-temperature combustion processes, such as those
occurring in motor vehicles and power plants.
\2\ EPA's monitoring requirements for NO2 are
codified at 40 CFR 50, Appendix F. In determining whether an
NO2 nonattainment area has attained the NAAQS, EPA
considers not only the most recent four quarters of monitored
ambient air quality data available, but also the previous four
quarters of monitoring data ``to assure that the current indication
of attainment was not the result of a single year's data reflecting
unrepresentative meteorological conditions.'' 43 FR 8962 (March 3,
1978).
---------------------------------------------------------------------------
The Federal CAA was substantially amended in 1990 to establish new
planning requirements and attainment deadlines for the NAAQS. Under
section 107(d)(1)(C) of the amended Act, an area designated
nonattainment prior to enactment of the 1990 amendments (as was the
South Coast Air Basin) was designated nonattainment by operation of
law.3 Under section 191 of the Act, an NO2 area
designated nonattainment under section 107(d) was required to submit to
EPA within 18 months of the
[[Page 39748]]
designation a plan meeting the requirements of Part D of the Act. Under
section 192 of the Act, such plans were required to provide for
attainment of the NAAQS as expeditiously as practicable but no later
than 5 years from the date of designation. In addition, Section 172 of
the Act contains general requirements applicable to SIPs for
nonattainment areas.
---------------------------------------------------------------------------
\3\ By the date of enactment of the 1990 amendments, the South
Coast was the only remaining area in the country designated as
nonattainment for NO2. For a description of the
boundaries of the South Coast Air Basin (also known as the Los
Angeles-South Coast Air Basin Area), see 40 CFR 81.305. The
nonattainment area includes all of Orange County and the non-desert
portions of Los Angeles, San Bernardino, and Riverside Counties.
---------------------------------------------------------------------------
The most fundamental of the CAA provisions for NO2
nonattainment areas is the requirement that the State submit a SIP
demonstrating attainment of the NAAQS as expeditiously as practicable
but no later than the applicable CAA deadline. Such a demonstration
must provide enforceable measures to achieve emission reductions each
year leading to emissions at or below the level predicted to result in
attainment of the NAAQS throughout the nonattainment area.
EPA has issued a ``General Preamble'' describing the Agency's
preliminary views on how EPA intends to act on SIPs submitted under
Title I of the Act. See generally 57 FR 13498 (April 16, 1992) and 57
FR 18070 (April 28, 1992). The reader should refer to the General
Preamble for a more detailed discussion of EPA's preliminary
interpretations of Title I requirements. In this rulemaking action, EPA
is applying these policies to the South Coast NO2 SIP
submittal, taking into consideration the specific factual issues
presented.
Section 107(d)(3)(E) of the 1990 CAA Amendments provides five
specific requirements that an area must meet in order to be
redesignated from nonattainment to attainment.
1. The area must have attained the applicable NAAQS;
2. The area must have a fully approved SIP under section 110 of
CAA;
3. The air quality improvement must be permanent and enforceable;
4. The area must have a fully approved maintenance plan pursuant to
section 175A of the CAA; and
5. The area must meet all applicable requirements under section 110
and Part D of the CAA.
II. Description of SIP Submittal
On February 5, 1997, CARB submitted as a revision to the California
SIP the 1997 Air Quality Management Plan (AQMP) for the South Coast Air
Basin (SCAB), Antelope Valley, and Coachella Valley, adopted by the
South Coast Air Quality Management District (SCAQMD) on November 15,
1996. This submittal, which included a revised South Coast
NO2 attainment plan and a maintenance plan, was found to be
complete on April 1, 1997, with respect to portions of the AQMP
relating to NO2 SIP requirements.4 The 1997
NO2 plan supersedes all prior submittals.5 This
submittal was supplemented by documentation providing information to
substantiate the redesignation request. The additional documentation
was submitted on March 4, 1998, and determined to be complete on May 5,
1998.
---------------------------------------------------------------------------
\4\ EPA adopted the completeness criteria on February 16, 1990
(55 FR 5830) and, pursuant to section 110(k)(1)(A) of the CAA,
revised the criteria on August 26, 1991 (56 FR 42216).
\5\ The initial NO2 SIP for the South Coast was
adopted on April 3, 1992, and submitted on May 15,1992. EPA did not
act on this plan since significant revisions to the emissions
inventory and control strategy were already in progress. The plan
was revised as part of a 1994 AQMP update, which was adopted on
September 9, 1994, and submitted on November 15, 1994. A revision to
the 1994 AQMP was adopted on April 12, 1996, and submitted on July
10, 1996. On January 8, 1997, EPA approved the portions of the 1994
AQMP (as revised in 1996) relating to ozone, including the
commitments to adopt additional measures to reduce emissions of
volatile organic compounds (VOC) and oxides of nitrogen
(NOX).
---------------------------------------------------------------------------
This 1997 NO2 plan provides, among other things, a
demonstration of attainment of the NO2 NAAQS, updated
historic and projected emission inventories, amended contingency
measures, and corrected air quality modeling analyses using the revised
inventories.
III. EPA Review of the SIP Submittal
A. Attainment Plan
1. Procedural Requirements
Both the SCAQMD and CARB have satisfied applicable statutory and
regulatory requirements for reasonable public notice and hearing prior
to adoption of the plan. The SCAQMD conducted numerous public workshops
and public hearings prior to the adoption hearing on November 15, 1996,
at which the 1997 AQMP was adopted by the Governing Board of the SCAQMD
(Resolution No. 96-23). On January 23, 1997, the Governing Board of
CARB adopted the plan (Resolution No. 97-1). The plan was submitted to
EPA by Michael P. Kenny, Executive Officer of CARB, on February 5,
1997. The SIP submittal includes proof of publication for notices of
SCAQMD and CARB public hearings, as evidence that all hearings were
properly noticed.
Supplemental information from the SCAQMD and a formal redesignation
request by the State (Executive Order G-125-231) were formally
submitted to EPA by Michael P. Kenny on March 4, 1998. The supplemental
information was submitted pursuant to the resolutions by the Governing
Boards of SCAQMD and CARB in adopting the 1997 AQMP.
Therefore, EPA proposes to approve the NO2 plan as
meeting the procedural requirements of section 110(a)(1) of the CAA.
2. Emissions Inventory
Appendix III of the 1997 AQMP includes planning emission
inventories for NOX for the historical years 1987, 1990, and
1993. The plan also includes future year inventories through the year
2010, both with and without planned controls. The inventories detail
emissions from all stationary and mobile source categories.
EPA emissions inventory guidance allows approval of California's
motor vehicle emissions factors in place of the corresponding federal
emissions factors.6 The motor vehicle emissions factors used
in the plan were generated by the CARB EMFAC7G and BURDEN7G program.
The gridded inventory for motor vehicles was then produced using an
updated Caltrans Direct Travel Impact Model (DTIM2) to combine EMFAC7G
data with transportation modeling performed by the Southern California
Association of Governments (SCAG). SCAG also provided the socioeconomic
data used in the plan.
---------------------------------------------------------------------------
\6\ EPA's general guidance for preparing emission inventories is
referenced in Appendix B to the General Preamble (57 FR 18070, April
28, 1992).
---------------------------------------------------------------------------
The baseline emissions inventory meets CAA requirements in that it
is comprehensive, accurate, and current. EPA approves the emissions
inventory portion of the plan as meeting the requirements of section
172(c)(3) of the CAA.
3. Attainment Demonstration
The 1990 CAA Amendments required the South Coast to demonstrate
attainment no later than November 15, 1995.7 The
demonstration must show that emissions will be (or have been) reduced
to levels at which the NO2 NAAQS will not be exceeded. This
means that the SIP must show that the annual arithmetic mean of
NO2 ambient concentrations will not exceed 0.053 ppm at any
location within the nonattainment area.
---------------------------------------------------------------------------
\7\ The South Coast area was designated nonattainment for
NO2 before the date of enactment of the 1990 amendments,
but the area lacked a fully approved SIP for NO2.
Consequently, the area was subject to the provisions of CAA section
191(b), which required submittal of an attainment plan within 18
months of enactment of the 1990 amendments (or May 15, 1992), and
section 192(b), which required attainment within 5 years after the
date of enactment of the amendments (or November 15, 1995).
---------------------------------------------------------------------------
The peak annual arithmetic mean concentrations for all monitoring
stations in the South Coast have been
[[Page 39749]]
0.0507 ppm in 1992, 0.0499 ppm in 1993, 0.0499 ppm in 1994, 0.0464 ppm
in 1995, 0.0461 ppm in 1996, and 0.043 ppm in 1997. Thus, the South
Coast has not exceeded the NO2 NAAQS since 1991 at any of
the 24 monitoring locations in the air basin.
The South Coast monitoring network is reviewed annually by CARB and
EPA, and has been determined to be generally reflective of air quality
throughout the air basin. Periodic CARB and EPA reviews also confirm
that the data collected has met applicable Federal standards for
quality assurance.
As discussed below in the description of the maintenance plan
provisions, the SCAQMD has also performed modeling for key locations in
the air basin to show that future NO2 concentrations will
remain below the NAAQS, taking credit for only those controls that were
already fully adopted in regulatory form by September 30, 1996. This
modeling shows a continuing decline in NO2 concentrations
throughout the air basin.
EPA approves the attainment demonstration portion of the plan as
meeting the requirements of sections 192(b) of the CAA, since it
demonstrates that the area attained the NAAQS before the applicable
deadline of November 15, 1995.
4. Additional Attainment Plan Requirements
Section 172(c)(1) requires that plans provide for the
implementation of all reasonably available control measures (RACMs) as
expeditiously as practicable, including the adoption of reasonably
available control technology (RACT). In numerous prior actions, EPA has
approved NOX RACT regulations for the SCAQMD. The SCAQMD's
extensive NOX regulations are generally recognized as among
the most stringent and comprehensive in the nation. Therefore, EPA
approves the NO2 plan with respect to the RACM requirement
of section 172(c)(1).
Section 172(c)(2) of the CAA requires that nonattainment area plans
require reasonable further progress (RFP), which section 171(1) defines
as ``annual incremental reductions in emissions of the relevant air
pollutant as are required * * * for the purpose of ensuring attainment
* * * by the applicable date.'' The emissions inventory data included
in the 1997 AQMP and supplement show significant annual declines in
NOX emissions from 1990 through the present. These
reductions, derived from SCAQMD stationary and area source controls and
CARB mobile source controls, were sufficient to prevent violations of
the NO2 NAAQS after 1991, several years before the statutory
attainment deadline of 1995. Therefore, EPA approves the plan as
meeting the RFP requirements of section 172(c)(2).
CAA sections 172(c)(4) and (5) require that nonattainment plans
quantify emissions from major new or modified stationary sources, and
include a permit program for these sources that meets the requirements
of section 173. The 1997 plan's emissions inventory includes
projections of emissions from new sources. EPA has previously approved
the South Coast's permit program (Regulation XIII) as meeting the
requirements of the CAA and EPA's New Source Review regulations. See 61
FR 64291 (December 4, 1996). Therefore, EPA approves the plan as
meeting the new source requirements of sections 172(c)(4) and (5) of
the CAA.
CAA section 172(c)(9) requires that nonattainment plans include
contingency measures to take effect if the area fails to meet RFP or to
attain by the applicable deadline. Since the area attained the
NO2 NAAQS before its deadline, this requirement is no longer
germane. In Section III.B., below, EPA addresses the contingency
measure requirement for the NO2 maintenance plan.
B. Maintenance Plan and Redesignation
1. Attainment of the NAAQS
The supplemental information submitted on March 4, 1998, includes
Attachment A, which presents a table displaying NO2 annual
arithmetic average values for all South Coast monitors for the period
1976 through 1996. This table indicates that the last year with an
NO2 violation was 1991, when the Pomona site had a 0.0550
ppm value, slightly above the 0.053 ppm NAAQS. During the most recent
year shown in the submittal (1996), only 5 of 23 stations had values
above 0.0400 ppm. The peak value, at the East San Fernando Valley site,
was 0.0461 ppm, approximately 15% below the NAAQS. Data for 1997
entered in EPA's Aerometric Information Retrieval System (AIRS) show
that air quality has improved further, with a peak concentration of
0.043 ppm for the year, almost 20% below the NAAQS. The docket for this
rulemaking includes the SCAQMD data summary and the AIRs data for 1997.
The South Coast more than meets applicable EPA redesignation
requirements for NO2, since the area has reached and then
sustained attainment by having had no exceedances of the NAAQS for 6
complete, consecutive calendar years.
2. Approval of the Applicable Implementation Plan
As set forth in Section III.A. above, this criterion for
redesignation is satisfied because the NO2 plan for the
South Coast is fully approved.
3. Improvement in Air Quality Due to Permanent and Enforceable Measures
Redesignation to attainment requires that the improvements in air
quality must be shown to have occurred because of enforceable controls,
rather than as a result of temporary economic conditions or favorable
meteorology. The South Coast NOX emissions inventory shows
increases in activity levels for most of the significant categories
(including motor vehicle use) during the years with no NO2
violations. This shows that the reductions in NOX emissions
are not due to an economic recession, but are associated with the
impact of permanent and enforceable CARB controls on mobile source
emissions and SCAQMD regulations on stationary and area sources. Fleet
turnover and progressively more stringent CARB requirements for future
year vehicles and engines are expected to sustain this continuing
decline in areawide NOX emissions, despite projected growth.
Therefore, this redesignation criterion is met.
4. Fully Approved Maintenance Plan
Section 175A of the CAA requires States to submit maintenance plans
for areas eligible for redesignation to attainment. The maintenance
plan must include four elements: an emissions inventory, a
demonstration that the NAAQS will be maintained for at least 10 years
from the date of redesignation, contingency measures, and a commitment
to submit a revised maintenance SIP eight years after the area is
redesignated to attainment.
a. Emissions inventory. As discussed above, the 1997 plan includes
baseline inventory data for 1987, 1990, and 1993, and thus covers the
period associated with attaining the NAAQS, as required for maintenance
plans.8
---------------------------------------------------------------------------
\8\ See, for example, the General Preamble at 57 FR 13563 (April
16, 1992).
---------------------------------------------------------------------------
As discussed above in Section II, the emission inventories meet
applicable inventory requirements and EPA also approves the inventory
portions of the plan under section 175A.
b. Demonstration of maintenance. For the maintenance demonstration,
the plan must either demonstrate that the future year inventory will
not exceed the inventory that existed at the time of the request for
redesignation, or include a modeling analysis showing that the
[[Page 39750]]
future mix of emissions, assuming existing SIP controls, will not cause
violations of the NAAQS.
The 1997 NO2 plan projects baseline emissions to 2010.
The table below, labeled ``South Coast NOX Emissions,''
shows the decline in NOX emissions from 1993 through 2010,
assuming no new control measures. Projections are made for Pomona
because that area has generally experienced the highest measured annual
NO2 concentrations in the air basin.
South Coast NOX Emissions in tons per winter day for the South Coast Air
Basin and the Pomona Area
[1997 AQMP, Appendix V, Table 1-1]
------------------------------------------------------------------------
Year SCAB Pomona
------------------------------------------------------------------------
1993................................................ 1284 36.7
2000................................................ 960 28.0
2010................................................ 759 21.9
------------------------------------------------------------------------
The SCAQMD also employed a linear rollback modeling approach,
assuming that ambient concentrations are directly proportional to
emissions in adjacent areas. The analysis used NO2/
NOX ratios averaged over the period 1992-4 for each site.
The results of this modeling analysis show annual average
NO2 concentrations for a 2010 baseline scenario, assuming
reductions only from existing regulations. At the peak site (Pomona),
the projected concentration is approximately 0.030 ppm, more than 45%
below the NAAQS.
c. Contingency measures. Maintenance plans for attainment areas
must include contingency provisions, or extra measures beyond those
needed for attainment, to offset any unexpected increase in emissions
and ensure that the standard is maintained (175(A)(d)). Typically,
contingency measures are held in reserve and implemented only if an
area violates the standard in the future. However, the California SIP
already includes fully adopted regulations which will generate (as
shown above) reductions in NOX emissions in future years
that will provide an ample margin of safety to ensure maintenance of
the standard and to provide adequate additional reductions to cover the
contingency requirements. These regulations include the California
motor vehicle and fuels program, California and Federal requirements
for nonroad vehicles and engines, and SCAQMD ``declining cap''
regulations for stationary sources: Rule 1135--Emissions of Oxides of
Nitrogen from Electric Power Generating Systems, and Regulation XX--
Regional Clean Air Incentives Market (RECLAIM). In addition, in acting
on the 1994 ozone SIP for the South Coast, EPA has approved and made
federally enforceable commitments by SCAQMD and CARB to adopt further
stationary and mobile source controls on NOX emissions.
These controls are scheduled to achieve more than 150 tons per day in
reductions of NOX emissions in the South Coast by the year
2010.9 Therefore, EPA approves the contingency measure
provisions under section 175A, based on the regulations and enforceable
commitments that have already been incorporated into the SIP.
---------------------------------------------------------------------------
\9\ See 62 FR 1150-1187 (January 8, 1997), EPA's final approval
of the California ozone SIPs, which lists the federally approved
CARB and SCAQMD measures, along with both the VOC and NOX
reductions associated with the measures for each ozone milestone
year through 2010 (1999, 2002, 2005, 2008, and 2010).
---------------------------------------------------------------------------
d. Subsequent maintenance plan revisions. In accordance with
section 175A(b) of the CAA, the State has agreed to submit a revised
maintenance SIP eight years after the area is redesignated to
attainment. Such revised SIP will provide for maintenance for an
additional ten years. In California, nonattainment areas must update
their plans every 3 years to meet State law requirements, so even more
frequent updates to the maintenance plan are expected.
e. Approval of the maintenance plan and redesignation request. EPA
approves under section 110(k)(3) of the CAA the South Coast
NO2 maintenance plan as meeting the requirements of sections
110 and 175A of the CAA. Since all of the CAA section 107(d)(3)(E)
redesignation requirements have been met, EPA grants the request of the
State to redesignate the South Coast Air Basin to attainment for the
NO2 NAAQS.
IV. EPA Final Action
Under CAA section 110(k)(3), EPA approves the South Coast
NO2 plan portion of the 1997 AQMP as meeting the
requirements of CAA sections 110, 172, and 192 with respect to the
nonattainment plan requirements, and the requirements of CAA sections
110 and 175A with respect to the maintenance plan requirements. EPA is
redesignating the South Coast to attainment for NO2 under
CAA section 107.
EPA is taking these actions without prior proposal because the
Agency views this as noncontroversial and anticipates no adverse
comments. However, if EPA receives relevant adverse comments by August
24, 1998, then EPA will publish a document that withdraws the rule and
informs the public that the rule will not take effect. EPA will then
address those comments in a final action based upon the proposed rule,
which appears as a separate document in the proposed rules section of
this Federal Register publication. EPA will not institute a second
comment period. Any parties interested in commenting should do so at
this time. If no such comments are received, the public is advised that
this rule will be effective on September 22, 1998, and no further
action will be taken on the proposed rule.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future implementation
plan. Each request for revision to the state implementation plan shall
be considered separately in light of specific technical, economic, and
environmental factors and in relation to relevant statutory and
regulatory requirements.
V. Administrative Requirements
A. Executive Order 12866
The Office of Management and Budget (OMB) has exempted this
regulatory action from E.O. 12866 review.
B. Regulatory Flexibility Act
Under the Regulatory Flexibility Act, 5 U.S.C. 600 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.
Alternatively, EPA may certify that the rule will not have a
significant impact on a substantial number of small entities. Small
entities include small business, small not-for-profit enterprises and
government entities with jurisdiction over populations of less than
50,000.
SIP approvals under sections 110 and subchapter I, part D of the
CAA, do not create any new requirements, but simply approve
requirements that the State is already imposing. Therefore, because the
Federal SIP approval does not impose any new requirements, the
Administrator certifies that it does not have a significant impact on
any small entities affected. Moreover, due to the nature of the
Federal-State relationship under the CAA, preparation of a regulatory
flexibility analysis would constitute Federal inquiry into the economic
reasonableness of state action. The CAA forbids EPA to base its actions
concerning SIP's on such grounds. Union Electric Co. v. U.S.E.P.A., 427
U.S. 246, 256-66 (S.Ct. 1976); 42 U.S.C. 7410(a)(2).
C. Unfunded Mandates
Under sections 202 of the Unfunded Mandates Reform Act of 1995
[[Page 39751]]
(``Unfunded Mandates Act'') signed into law on March 22, 1995, EPA must
prepare a budgetary impact statement to accompany any proposed or final
rule that includes a Federal mandate that may result in estimated costs
to State, local, or tribal governments in the aggregate; or to the
private sector, of $100 million or more. Under Section 205, EPA must
select the most cost-effective and least burdensome alternative that
achieves the objectives of the rule and is consistent with statutory
requirements. Section 203 requires EPA to establish a plan for
informing and advising any small governments that may be significantly
or uniquely impacted by the rule.
EPA has also determined that this final action does not include a
mandate that may result in estimated costs of $100 million or more to
State, local, or tribal governments in the aggregate or to the private
sector. This Federal action approves pre-existing requirements under
State or local law, and imposes no new Federal requirements.
Accordingly, no additional costs to State, local, or tribal
governments, or to the private sector, result from this action.
D. Submission to Congress and the General Accounting Office
The Congressional Review Act, 5 U.S.C. Sec. 801 et seq., as added
by the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of the Congress and to the Comptroller
General of the United States. EPA will submit 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 United States
prior to publication of the rule in the Federal Register. This rule is
not a ``major'' rule as defined by 5 U.S.C. Sec. 804(2).
E. Petitions for Judicial Review
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by September 22, 1998. 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).)
F. Executive Order 13045
The final rule is not subject to E.O. 13045, entitled Protection of
Children from Environmental Health Risks and Safety Risks, because it
is not an ``economically significant'' action under E.O. 12866.
