Approval and Promulgation of Implementation Plans and Designation
of Areas for Air Quality Planning Purposes; State of Florida Change in
National Policy Regarding Applicability of Conformity Requirements to
Redesignation Requests
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: On February 7, 1995, the State of Florida, through the Florida
Department of Environmental Protection (FDEP), submitted a maintenance
plan and a request to redesignate the Tampa area from marginal
nonattainment to attainment for ozone (O3). The Tampa O3
nonattainment area consists of Hillsborough and Pinellas Counties.
Under the Clean Air Act as amended in 1990 (CAA), designations can be
revised if sufficient data are available to warrant such revisions and
the CAA redesignation requirements are satisfied. In this action, EPA
is approving Florida's request because it meets the maintenance plan
and redesignation requirements set forth in the CAA, and EPA is also
approving the 1990 base year emission inventory for the Tampa area.
DATES: This action will be effective February 5, 1996, unless adverse
or critical comments are received by January 8, 1996. If the effective
date is delayed, timely notice will be published in the Federal
Register.
ADDRESSES: Written comments on this action should be addressed to Joey
LeVasseur, at the EPA Regional Office listed below.

SUPPLEMENTARY INFORMATION: The Clean Air Act, as amended in 1977 (1977
Act) required areas that were designated nonattainment based on a
failure to meet the O3 national ambient air quality standard
(NAAQS) to develop SIPs with sufficient control measures to
expeditiously attain and maintain the standard. The Tampa-St.
Petersburg-Clearwater area (Tampa), comprised of Hillsborough and
Pinellas Counties, was designated under section 107 of the 1977 Act as
nonattainment with respect to the O3 NAAQS on March 3, 1978. [43
FR 8964, 40 CFR 81.310] In accordance with section 110 of the 1977 Act,
the State submitted a part D O3 SIP on April 30, 1979, which was
supplemented on August 27, 1979, and January 23, 1980, which EPA
conditionally approved on March 18, 1980, and fully approved on May 14,
1981, as meeting the requirements of section 110 and part D of the 1977
Act.
On November 15, 1990, the CAA Amendments of 1990 were enacted (1990
Amendments). [Pub. L. 101-549, 104 Stat. 2399, codified at 42 U.S.C.
7401-7671q] The nonattainment designation of Tampa was continued by
operation of law pursuant to section 107(d)(1)(C)(i) of the 1990
Amendments. Furthermore, it was classified as marginal for O3
according to section 181(a)(1). (See 56 FR 56694 (Nov. 6, 1991) and 57
FR 56762 (Nov. 30, 1992), codified at 40 CFR 81.310).
Tampa more recently has ambient monitoring data that show no
violations of the O3 NAAQS, during the period 1990 through 1994.
In addition, there have been no exceedances reported for the 1995
O3 season. Therefore, in an effort to comply with the 1990
Amendments and to ensure continued attainment of the NAAQS, Florida
submitted an O3 maintenance SIP for the Tampa area on February 7,
1995, and also requested redesignation of the area to attainment with
respect to the O3 NAAQS.
The 1990 Amendments revised section 107(d)(1)(E) to provide 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 meet all relevant requirements under section 110
and part D of the CAA;
3. The area must have a fully approved SIP under section 110(k) of
the CAA;
4. The air quality improvement must be permanent and enforceable;
and
5. The area must have a fully approved maintenance plan pursuant to
section 175A of the CAA.
The Florida redesignation request for the Tampa area meets the five
requirements of section 107(d)(3)(E), noted above. The following is a
brief description of how the State has fulfilled each of these
requirements. Because the maintenance plan is a critical element of the
redesignation request, EPA will discuss its evaluation of the
maintenance plan under its analysis of the redesignation request.
1. Attainment of the O3 NAAQS
The Florida request is based on an analysis of quality assured
O3 air quality data which is relevant to the maintenance plan and
to the redesignation request. The ambient O3 data for the calendar
years 1990 through
[[Page 62749]]
1992 shows an exceedance rate of less than 1.0 per year of the O3
NAAQS in the Tampa area. (See 40 CFR 50.9 and Appendix H). In addition,
there have been no ambient air exceedances in 1993, 1994 or to date in
1995 for O3. Because the Tampa area has complete quality-assured
data showing no violations of the standard over the most recent
consecutive three calendar year period, the Tampa area has met the
first statutory criterion of attainment of the O3 NAAQS. Florida
has committed to continue monitoring in this area in accordance with 40
CFR part 58.
2. Meeting Applicable Requirements of Section 110 and Part D
On May 14, 1981, EPA fully approved Florida's SIP for the Tampa
area as meeting the requirements of section 110(a)(2) and part D of the
1977 Act (46 FR 26640). The 1990 Amendments, however, modified section
110(a)(2) and, under part D, revised section 172 and added new
requirements for all nonattainment areas. Therefore, for purposes of
redesignation, to meet the requirement that the SIP contain all
applicable requirements under the CAA, EPA has reviewed the SIP to
ensure that it contains all measures that were due under the 1990
Amendments prior to or at the time the State submitted its
redesignation request. EPA interprets section 107(d)(3)(E)(v) to mean
that for a redesignation request to be approved, the state has met all
requirements that applied to the subject area prior to the submission
of a complete redesignation request. Requirements of the CAA that come
due subsequently continue to be applicable at those later dates (see
section 175A(c)) and, if the redesignation is disapproved, the state
remains obligated to fulfill those requirements.
A. Section 110 Requirements
Although section 110 was amended by the 1990 Amendments, the Tampa
SIP meets the requirements of amended section 110(a)(2). A number of
the requirements did not change in substance and, therefore, EPA
believes that the pre-amendment SIP met these requirements. As to those
requirements that were amended, (see 57 FR 27936 and 23939, June 23,
1993), many are duplicative of other requirements of the CAA. EPA has
analyzed the SIP and determined that it is consistent with the
requirements of amended section 110(a)(2).
B. Part D Requirements
Before Tampa may be redesignated to attainment, it also must have
fulfilled the applicable requirements of part D. Under part D, an
area's classification indicates the requirements to which it will be
subject. Subpart 1 of part D sets forth the basic nonattainment
requirements applicable to all nonattainment areas, classified as well
as nonclassifiable. Subpart 2 of part D establishes additional
requirements for nonattainment areas classified under table 1 of
section 181(a). The Tampa area was classified as marginal (See 56 FR
56694, codified at 40 CFR 81.530). Therefore, in order to be
redesignated to attainment, the State must meet the applicable
requirements of subpart 1 of part D, specifically sections 172(c) and
176, and is subject to requirements of subpart 2 of part D.
B.1. Subpart 1 of part D--Section 172(c) Plan Provisions
Under section 172(b), the Administrator established that States
containing nonattainment areas shall submit a plan or plan revision
meeting the applicable requirements of section 172(c) no later than
three years after an area is designated as nonattainment, i.e., unless
EPA establishes an earlier date. EPA had not determined that these
requirements were applicable to classified O3 nonattainment areas
on or before February 7, 1995, the date that the State of Florida
submitted a complete redesignation request for the Tampa area.
Therefore, the State was not required to meet these requirements for
purposes of redesignation. EPA has determined that the section
172(c)(2) reasonable further progress (RFP) requirement was not
applicable to the Tampa redesignation. Also the section 172(c)(9)
contingency measures and additional section 172(c)(1) non-RACT
reasonable available control measures (RACM) beyond what may already be
required in the SIP are no longer necessary.
The section 172(c)(3) emissions inventory requirement has been met
by the submission and approval (in this action) of the 1990 base year
inventory required under subpart 2 of part D, section 182(a)(1).
As for the section 172(c)(5) NSR requirement, EPA has determined
that areas being redesignated need not comply with the NSR requirement
prior to redesignation provided that the area demonstrates maintenance
of the standard without part D NSR in effect. See memorandum from Mary
Nichols, Assistant Administrator for Air and Radiation, dated October
14, 1994, entitled Part D New Source Review (part D NSR) Requirements
for Areas Requesting Redesignation to Attainment. The rationale for
this view is described fully in that memorandum, and is based on the
Agency's authority to establish de minimis exceptions to statutory
requirements. See Alabama Power Co. v. Costle, 636 F. 2d 323, 360-61
(D.C. Cir. 1979). However, the State of Florida does have a fully
approved part D NSR rule.
Finally, for purposes of redesignation, the Tampa SIP was reviewed
to ensure that all requirements of section 110(a)(2), containing
general SIP elements, were satisfied. As noted above, EPA believes the
SIP satisfies all of those requirements.
B.2. Subpart 1 of Part D--Section 176 Conformity Plan Provisions
Section 176(c) of the CAA requires States to revise their SIPs to
establish criteria and procedures to ensure that Federal actions,
before they are taken conform to the air quality planning goals in the
applicable State SIP. The requirement to determine conformity applies
to transportation plans, programs and projects developed, funded or
approved under Title 23 U.S.C. or the Federal Transit Act
(``transportation conformity''), as well as to all other Federal
actions (``general conformity''). Section 176 further provides that the
conformity revisions to be submitted by the States must be consistent
with Federal conformity regulations that the CAA required EPA to
promulgate. Congress provided for the State revisions to be submitted
one year after the date for promulgation of final EPA conformity
regulations. When that date passed without such promulgation, EPA's
General Preamble for the Implementation of Title I informed States that
its conformity regulations would establish a submittal date (see 57 FR
13498, 13557 (April 16, 1992)).
EPA promulgated final transportation conformity regulations on
November 24, 1993 (58 FR 62118), and general conformity regulations on
November 30, 1993 (58 FR 63214). These conformity rules require that
States adopt both transportation and general conformity provisions in
the SIP for areas designated nonattainment or subject to a maintenance
plan approved under CAA section 175A. Pursuant to 40 CFR 51.396 of the
transportation conformity rule and 40 CFR 51.851 of the general
conformity rule, the State of Florida is required to submit a SIP
revision containing transportation conformity criteria and procedures
consistent with those established in the Federal rule by November 25,
1994. Similarly, the State of Florida is required to submit a SIP
revision containing general conformity criteria and procedures
consistent with those established in the Federal rule by
[[Page 62750]]
December 1, 1994. The conformity rules for Florida have not yet been
approved.
Although this redesignation request was submitted to EPA after the
due dates for the SIP revisions for transportation conformity [58 FR
62188] and general conformity [58 FR 63214] rules, EPA believes it is
reasonable to interpret the conformity requirements as not being
applicable requirements for purposes of evaluating the redesignation
request under section 107(d). The rationale for this is based on a
combination of two factors. First, the requirement to submit SIP
revisions to comply with the conformity provisions of the Act continues
to apply to areas after redesignation to attainment. Therefore, the
State remains obligated to adopt the transportation and general
conformity rules even after redesignation and would risk sanctions for
failure to do so. While redesignation of an area to attainment enables
the area to avoid further compliance with most requirements of section
110 and part D, since those requirements are linked to the
nonattainment status of an area, the conformity requirements apply to
both nonattainment and maintenance areas. Second, EPA's federal
conformity rules require the performance of conformity analyses in the
absence of state-adopted rules. Therefore, a delay in adopting State
rules does not relieve an area from the obligation to implement
conformity requirements.
Because areas are subject to the conformity requirements regardless
of whether they are redesignated to attainment and must implement
conformity under Federal rules if State rules are not yet adopted, EPA
believes it is reasonable to view these requirements as not being
applicable requirements for purposes of evaluating a redesignation
request.
Therefore, with this notice, EPA is modifying its national policy
regarding the interpretation of the provisions of section 107(d)(3)(E)
concerning the applicable requirements for purposes of reviewing an
ozone redesignation request. Under this new policy, for the reasons
just discussed, EPA believes that the ozone redesignation request for
the Tampa area may be approved notwithstanding the lack of submitted
and approved state transportation and general conformity rules.
B.3. Subpart 2 of Part D--Section 182(a) Requirements
The CAA was amended on November 15, 1990, Public Law 101-549, 104
Stat. 2399, codified at 42 U.S.C. 7401-7671q. EPA was required to
classify O3 nonattainment areas according to the severity of their
problem. The Tampa area was designated as marginal O3
nonattainment (See 40 CFR 81.310). Because this area is marginal, the
area must meet section 182(a) of the CAA. EPA has analyzed the SIP and
determined that it is consistent with the requirements of amended
section 182. Below is a summary of how the area has met the
requirements of these sections.
(1) Emissions Inventory
The CAA required an inventory of all actual emissions from all
sources, as described in section 172(c)(3) by November 15, 1992. On
November 16, 1992, FDEP submitted an emission inventory for the Tampa
area. This notice is approving the base year inventory for the Tampa
area.
(2) Reasonably Available Control Technology (RACT)
To be redesignated, all SIP revisions required by section
182(a)(2)(A) and 182(b)(2) concerning RACT requirements must have been
submitted to EPA and fully approved. Florida has met all RACT
requirements.
(3) Emissions Statements
Section 182(a)(3) of the CAA required a SIP submission by November
15, 1992, to require stationary sources of NOX and VOCs to provide
statements of actual emissions. Florida submitted an annual emissions
statement SIP revision on November 13, 1992. This revision was approved
in the Federal Register on August 4, 1994.
3. Fully Approved SIP Under Section 110(k) of the CAA
Based on the approval of provisions under the pre-amended CAA and
EPA's prior approval of SIP revisions under the 1990 Amendments, EPA
has determined that the Tampa area has a fully approved SIP under
section 110(k), which also meets the applicable requirements of section
110 and part D as discussed above.
4. Improvement in Air Quality Due to Permanent and Enforceable Measures
Under the pre-amended CAA, EPA approved the Florida SIP control
strategy for the Tampa nonattainment area, satisfied that the rules and
the emission reductions achieved as a result of those rules were
enforceable. The control measures to which the emission reductions are
attributed are VOC RACT regulations, the Federal Motor Vehicle Control
Program (FMVCP), and lower Reid Vapor Pressure (RVP). VOC emissions
from stage I sources were reduced by 40% in 1990 due to VOC RACT. The
FMVCP reduced VOC emissions from motor vehicles by 14.2% from 1988 to
1990. The reduction in RVP from 10.8 psi in 1988 to 9.0 psi in 1990 has
reduced summertime VOC mobile source emissions by 30.8%.
In association with its emission inventory discussed below, the
State of Florida has demonstrated that actual enforceable emission
reductions are responsible for the air quality improvement and that the
VOC emissions in the base year are not artificially low due to local
economic downturn. EPA finds that the combination of existing EPA-
approved state and federal measures contribute to the permanence and
enforceability of reduction in ambient O3 levels that have allowed
the area to attain the NAAQS.
5. Fully Approved Maintenance Plan Under Section 175A
Section 175A of the CAA sets forth the elements of a maintenance
plan for areas seeking redesignation from nonattainment to attainment.
The plan must demonstrate continued attainment of the applicable NAAQS
for at least ten years after the Administrator approves a redesignation
to attainment. Eight years after the redesignation, the State must
submit a revised maintenance plan which demonstrates attainment for the
ten years following the initial ten-year period. To provide for the
possibility of future NAAQS violations, the maintenance plan must
contain contingency measures, with a schedule for implementation,
adequate to assure prompt correction of any air quality problems. In
this notice, EPA is approving the State of Florida's maintenance plan
for the Tampa area because EPA finds that Florida's submittal meets the
requirements of section 175A.
A. Emissions Inventory--Base Year Inventory
On November 16, 1992, the State of Florida submitted comprehensive
inventories of VOC, NOX, and CO emissions from the Tampa area. The
inventories include biogenic, area, stationary, and mobile sources
using 1990 as the base year for calculations to demonstrate
maintenance. The 1990 inventory is considered representative of
attainment conditions because the NAAQS was not violated during 1990.
EPA is approving the 1990 base year inventory in this document.
The State submittal contains the detailed inventory data and
summaries by county and source category. The comprehensive base year
emissions inventory was submitted in the NEDS format. Finally, this
inventory was prepared in accordance with EPA guidance. It also
contains summary
[[Page 62751]]
tables of the base year and projected maintenance year inventories.
EPA's TSD contains more in-depth details regarding the base year
inventory for the Tampa area.

B. Demonstration of Maintenance--Projected Inventories
Total VOC and NOX emissions were projected from 1990 base year
out to 2005, with interim years of 1994, 1997, and 2000. These
projected inventories were prepared in accordance with EPA guidance.
The projections show that VOC emissions are expected to decrease 38.34
tons or 8.85% from the level of the base year inventory during this
time period. The NOX emissions do show a slight increase of 23.99
tons or 4.87% from 1990 to 2005, but the State has demonstrated as
discussed below that the projected increases will not adversely affect
the maintenance of the O3 NAAQS.
The Empirical Kinetics Modeling Approach (EKMA) was used to
demonstrate the impact of NOX emission increases on maximum
O3 formation. The EKMA analysis showed that the projected future
mix of emissions will not cause a violation of the NAAQS. EPA EKMA
guidance documents were used in developing model inputs. The model was
run using 1988 meteorological conditions and monitored O3,
NOX and nonmethane organic compound (NMOC) concentration data for
May 16, 1988, June 3, 1988, and June 23, 1988, and was run in the EKMA
calculate mode. These days had observed O3 maximum concentrations
of 0.118, 0.113, and 0.115 parts per million (ppm) respectively. The
monitored NMOC/NOX ratios of 6.876, 8.298, and 5.180 were used as
input. The EKMA predicted a minimum decrease in O3 concentration
of 1.5% from 1990 to 2005.
The model output indicated a continual decrease in the maximum
model-predicted O3 with each increase in NOX emissions over
the 1990 base case inventory. Additionally, the modeling indicated that
the mix of emissions as indicated in the 2005 inventory (11.4% VOC
reductions and 4.8% NOX increase over the 1990 inventory) produced
lower O3 levels than the base case. Thus, the analysis indicates
that, not withstanding the projected increase in NOX emissions,
the Tampa area should continue to maintain the standard throughout the
maintenance period.
C. Contingency Plan
The level of VOC emissions in the Tampa area will largely determine
its ability to stay in compliance with the O3 NAAQS in the future.
Despite the State's best efforts to demonstrate continued compliance
with the NAAQS, the ambient air pollutant concentrations may exceed or
violate the NAAQS. Therefore, Florida has provided contingency measures
with a schedule for implementation in the event of a future O3 air
quality problem. In the case of a violation of the O3 NAAQS, the
plan contains a contingency to implement additional control measures
such as reinstatement of NSR, less volatile or reformulated gasoline,
expansion of control strategies to adjacent counties for VOC and/or
NOX and to new CTG categories, or an
[[Page 62752]]
enhanced vehicle emissions inspection program. A complete description
of these contingency measures and their triggers can be found in the
State's submittal. EPA finds that the contingency measures provided in
the State submittal meet the requirements of section 175A(d) of the
CAA.
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.
Final Action
In this action, EPA is approving the Tampa area O3 maintenance
plan submitted on February 7, 1995, because it meets the requirements
of section 175A. In addition, the Agency is approving the request and
redesignating the Tampa nonattainment area to attainment, because the
State has demonstrated compliance with the requirements of section
107(d)(3)(E) for redesignation. EPA is also approving the 1990 base
year emissions inventory for the Tampa area submitted on November 16,
1992. The EPA is publishing this action without prior proposal because
the Agency views this as a noncontroversial amendment and anticipates
no adverse comments. However, in a separate document in this Federal
Register publication, the EPA is proposing to approve the SIP revision
should adverse or critical comments be filed. This action will be
effective February 5, 1996, unless, within 30 days of its publication,
adverse or critical comments are received. If the EPA receives such
comments, this action will be withdrawn before the effective date by
publishing a subsequent document that will withdraw the final action.
All public comments received will then be addressed in a subsequent
final rule based on this action serving as a proposed rule. The EPA
will not institute a second comment period on this action. Any parties
interested in commenting on this action should do so at this time. If
no such comments are received, the public is advised that this action
will be effective February 5, 1996.
The O3 SIP is designed to satisfy the requirements of part D
of the CAA and to provide for attainment and maintenance of the O3
NAAQS. This final redesignation should not be interpreted as
authorizing the State to delete, alter, or rescind any of the VOC or
NOX emission limitations and restrictions contained in the approved
O3 SIP. Changes to O3 SIP VOC regulations rendering them less
stringent than those contained in the EPA approved plan cannot be made
unless a revised plan for attainment and maintenance is submitted to
and approved by EPA. Unauthorized relaxations, deletions, and changes
could result in both a finding of non-implementation [section 173(b) of
the CAA] and in a SIP deficiency call made pursuant to section
110(a)(2)(H) of the CAA.
Under section 307(b)(1) of the Act, 42 U.S.C. 7607 (b)(1),
petitions for judicial review of this action must be filed in the
United States Court of Appeals for the appropriate circuit by February
5, 1996. Filing a petition for reconsideration by the Administrator of
this final rule does not affect the finality of this rule for 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) of the Act, 42 U.S.C. 7607 (b)(2).)
This action has been classified as a Table 3 action for signature
by the Regional Administrator under the procedures published in the
Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a
July 10, 1995 memorandum from Mary Nichols, Assistant Administrator for
Air and Radiation. The Office of Management and Budget (OMB) has
exempted this regulatory action from E.O. 12866 review.
Nothing in this action shall be construed as permitting or allowing
or establishing a precedent for any future request for a revision to
any SIP. Each request for revision to the SIP shall be considered
separately in light of specific technical, economic, and environmental
factors and in relation to relevant statutory and regulatory
requirements.
Under the Regulatory Flexibility Act, 5 U.S.C. section 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 sections 603
and 604. Alternatively, EPA may certify that the rule will not have a
significant economic 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 Office of Management and Budget has exempted
this rule from the requirements of section 3 of Executive Order 12291.
SIP approvals under section 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, I certify that it does
not have a significant impact on small entities. 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 SIPs 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. sections 7410
(a)(2) and 7410 (k)(3).
Redesignation of an area to attainment under section 107(d)(3)(E)
of the CAA does not impose any new requirements on small entities.
Redesignation is an action that affects the status of a geographical
area and does not impose any regulatory requirements on sources. The
Administrator certifies that the approval of the redesignation request
will not affect a substantial number of small entities.
Unfunded Mandates
Under sections 202, 203, and 205 of the Unfunded Mandates Reform
Act of 1995 (``Unfunded Mandates Act''), signed into law on March 22,
1995, EPA must undertake various actions in association with proposed
or final rules that include a Federal mandate that may result in
estimated costs of $100 million or more to the private sector, or to
State, local, or tribal governments in the aggregate.
Through submission of this state implementation plan or plan
revision, the State and any affected local or tribal governments have
elected to adopt the program provided for under section 110 of the
Clean Air Act. These rules may bind State, local and tribal governments
to perform certain actions and also require the private sector to
perform certain duties. To the extent that the rules being approved by
this action will impose no new requirements; such sources are already
subject to these regulations under State law. Accordingly, no
additional costs to State, local, or tribal governments, or to the
private sector, result from this action. 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.
