40 CFR Parts 52 and 81
[NC58-2-6082; FRL-4856-1]
Approval and Promulgation of Implementation Plans and Designation
of Areas for Air Quality Planning Purposes; State of North Carolina
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: On November 13, 1992, the State of North Carolina, through the
North Carolina Department of Environment, Health, and Natural Resources
(NCDEHNR), submitted a maintenance plan and a request to redesignate
the Raleigh/Durham area (classified as a moderate nonattainment area)
from nonattainment to attainment for ozone (O3). The O3
nonattainment area includes the following counties: Durham, Wake, and
the Dutchville Township portion of Granville. Under the Clean Air Act,
designations can be changed if sufficient data are available to warrant
such changes. In this action, EPA is approving the State of North
Carolina's submittal because it meets the maintenance plan and
redesignation requirements. The approved maintenance plan will become a
federally enforceable part of the SIP for the Raleigh/Durham area.
On January 15, 1993, in a letter from Patrick Tobin to Governor
James Hunt, the EPA notified the State of North Carolina that the EPA
had made a finding of failure to submit required programs for the
nonattainment area. EPA's redesignation of the Raleigh/Durham area to
attainment abrogates those requirements for this area. Therefore, the
sanctions and federal implementation plan clocks begun by those
findings are stopped at the time of the redesignation.
EFFECTIVE DATE: This final rule will be effective June 17, 1994, unless
notice is received by May 18, 1994, that someone wishes to submit
adverse or critical comments. If the effective date is delayed, timely
notice will be published in the Federal Register.
ADDRESSES: Written comments should be sent to Bill Eckert at the EPA
address in Atlanta, Georgia listed below. Copies of the redesignation
request and the State of North Carolina's submittal are available for
public review during normal business hours at the addresses listed
below. EPA's technical support document (TSD) is available for public
review during normal business hours at the EPA addresses listed below.

SUPPLEMENTARY INFORMATION: On November 15, 1990, the Clean Air Act
Amendments of 1990 (CAA) were enacted. (Pub. L. 101-549, 104 Stat.
2399, codified at 42 U.S.C. 7401-7671q.) Under section 107(d)(1), in
conjunction with the Governor of North Carolina, EPA designated the
Raleigh/Durham area as nonattainment because the area violated the
O3 standard during the period from 1987 through 1989. Furthermore,
upon designation, the Raleigh/Durham area was classified as moderate
under section 181(a)(1). (See 56 FR 56694 (November 6, 1991) and 57 FR
56762 (November 30, 1992), codified at 40 CFR 81.334.)
The Raleigh/Durham area more recently has ambient monitoring data
that show no violations of the O3 National Ambient Air Quality
Standards (NAAQS), during the period from 1989 through 1992. Therefore,
in an effort to comply with the CAA and to ensure continued attainment
of the NAAQS, on November 13, 1992, the State of North Carolina
submitted for parallel processing an O3 maintenance SIP for the
Raleigh/Durham area and requested redesignation of the area to
attainment with respect to the O3 NAAQS. On January 13, 1993, the
NCDEHNR submitted evidence that a public hearing was held on the
maintenance plan and on July 8, 1993, the maintenance plan became State
effective. In addition, there have been no violations reported for the
1993 O3 season.
On August 11, 1993, Region IV determined that the information
received from the NCDEHNR constituted a complete redesignation request
under the general completeness criteria of 40 CFR part 51, appendix V,
sections 2.1 and 2.2. However, for purposes of determining what
requirements are applicable for redesignation purposes, EPA believes it
is necessary to identify when NCDEHNR first submitted a redesignation
request that meets the completeness criteria. EPA noted in a previous
policy memorandum that parallel processing requests for submittals
under the CAA, including redesignation submittals, would not be
determined complete. See the memorandum entitled ``State Implementation
Plan (SIP) Actions Submitted in Response to Clean Air Act (Act)
Deadlines'' from John Calcagni to Air Programs Division Directors,
Regions I-X, dated October 28, 1992 (Memorandum). The rationale for
this conclusion was that the parallel processing exception to the
completeness criteria (40 CFR part 51, appendix V, section 2.3) was not
intended to extend statutory due dates for mandatory submittals. (See
Memorandum at 3-4.) However, since requests for redesignation are not
mandatory submittals under the CAA, EPA believes that it must change
its policy with respect to redesignation submittals to conform to the
existing completeness criteria. Therefore, EPA believes, the parallel
processing exception to the completeness criteria may be applied to
redesignation request submittals, at least until such time as the EPA
decides to revise that exception. NCDEHNR submitted a redesignation
request on November 13, 1992. In the November 13 submittal, NCDEHNR
submitted the maintenance plan, thereby including the final element to
make the November 13, 1992, request for parallel processing complete
under the parallel processing exception to the completeness criteria.
When the maintenance plan became state effective on July 8, 1993, the
State of North Carolina no longer needed parallel processing for the
redesignation request and maintenance plan. Therefore, the EPA informed
the State of North Carolina on August 11, 1993, that the redesignation
request and maintenance plan submittals were complete under the general
completeness criteria.
The North Carolina redesignation request for the Raleigh/Durham
area meets the five requirements of section 107(d)(3)(E) for
redesignation to attainment. The following is a brief description of
how the State of North Carolina 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. The Area Must Have Attained the O3 NAAQS
The State of North Carolina's request is based on an analysis of
quality assured ambient air quality monitoring data which is relevant
to the maintenance plan and to the redesignation request. Most recent
ambient air quality monitoring data for calendar year 1989 through
calendar year 1992 show an expected exceedence rate of less than 1.0
per year of the O3 NAAQS in the Raleigh/Durham area. (See 40 CFR
50.9 and appendix H.) Because the Raleigh/Durham area has complete
quality-assured data showing no violations of the standard over the
most recent consecutive three calendar year period, the Raleigh/Durham
area has met the first statutory criterion of attainment of the O3
NAAQS. In addition, there were no violations reported for the 1993
O3 season. The State of North Carolina has committed to continue
monitoring in this area in accordance with 40 CFR part 58.
2. The Area Has Met All Applicable Requirements Under Section 110
and Part D of the Act
On April 17, 1980, and on September 10, 1980, EPA fully approved
North Carolina's SIP as meeting the requirements of section 110(a)(2)
and part D of the 1977 CAA (45 FR 26038 and 45 FR 59578). The amended
CAA, however, revised 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 reviewed
the North Carolina SIP to ensure that it contained all measures due
under the amended CAA prior to or at the time the State of North
Carolina submitted its redesignation request.
A. Section 110 Requirements
Although section 110 was amended, the Raleigh/Durham area 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 57 FR 27939 (June
23, 1992), 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 the Raleigh/Durham area 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 O3 nonattainment areas classified
under table 1 of section 181(a). The Raleigh/Durham area is classified
as moderate (See 56 FR 56694, codified at 40 CFR 81.334). The State of
North Carolina submitted their request for redesignation of the
Raleigh/Durham area prior to November 15, 1992. Therefore, in order to
be redesignated to attainment, the State of North Carolina must meet
the applicable requirements of subpart 1 of part D, specifically
sections 172(c) and 176, and the requirements of subpart 2 of part D,
which became due on or before November 13, 1992, the date the State
submitted a complete redesignation request.
B1. Subpart 1 of Part D--Section 172
Section 172(c) sets forth general requirements applicable to all
nonattainment areas. Under section 172(b), the section 172(c)
requirements are applicable as determined by the Administrator but no
later than three years after an area is designated as nonattainment.
EPA had not determined that these requirements were applicable to
classified O3 nonattainment areas on or before November 13, 1992,
the date that the State of North Carolina submitted a complete
redesignation request for the Raleigh/Durham area. Therefore, the State
of North Carolina was not required to meet these requirements for
purposes of redesignation.
Upon redesignation of this area to attainment, the Prevention of
Significant Deterioration (PSD) provisions contained in part C of title
I are applicable. On December 30, 1976, and on February 23, 1982, the
EPA approved the State of North Carolina's PSD program (41 FR 56805 and
47 FR 78376).
B2. Subpart 1 of Part D--Section 176 Conformity Plan Provisions
Section 176 of the CAA requires States to develop transportation/
air quality conformity procedures which are consistent with federal
conformity regulations. Section 176 provides that EPA must develop
federal conformity regulations, requiring states to submit these
procedures as a SIP revision by November 15, 1992. EPA promulgated
final conformity regulations on November 24, 1993 (transportation
conformity) and November 30, 1993 (general conformity). Since it was
impossible to establish a SIP revision date of November 15, 1992, in
these regulations, EPA established a regulatory submittal date of one
year after promulgation of the conformity regulations. The State of
North Carolina has committed in their maintenance plan to revise the
SIP to be consistent with the final federal regulations. In addition,
the State Air Quality Section will work closely with the State
Department of Transportation (DOT) and local transportation agencies to
assure that Transportation Improvement Programs (TIPs) in the
maintenance areas are consistent with and conform to the SIP and meet
federal requirements on conformity. This review process is being
extended to include all major projects regardless of source of funding,
as well as all federally funded projects. A complete description of the
conformity review process is included in the TSD prepared for this
notice.
B3. Subpart 2 of Part D
Under section 182(a)(2)(A) areas that retained a designation of
nonattainment for O3 under the amended CAA and that are classified
as marginal or above were required to fix their pre-amendment VOC RACT
SIPs. North Carolina was not required to submit VOC RACT fixups for
purposes of redesignating the Raleigh/Durham area because the Raleigh/
Durham area was not nonattainment before the 1990 amendments to the
CAA.
Under section 182(b), several requirements were due for moderate
O3 nonattainment areas on November 15, 1992, such as VOC RACT
catch-ups, Gasoline Vapor Recovery, New Source Review, and Emission
Statements. North Carolina failed to submit these measures for the
Raleigh/Durham area. On January 15, 1993, EPA made a finding of failure
to submit these measures by letter from Patrick M. Tobin, Acting
Regional Administrator, to James B. Hunt, Jr., Governor of North
Carolina. However these requirements are not applicable for purposes of
considering the State's redesignation request. For purposes of
redesignation, EPA must consider whether the State has met all
requirements that were applicable prior to the time the state submitted
the redesignation request. Since North Carolina submitted the
redesignation request for Raleigh/Durham on November 13, 1992, these
measures are not relevant for purposes of redesignation. Therefore, all
subpart 2 requirements that were applicable at the time the State
submitted its redesignation request have been met.
3. The Area Has a 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 amended CAA, EPA has
determined that the Raleigh/Durham 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. The Air Quality Improvement Must Be Permanent and Enforceable
Several control measures have come into place since the Raleigh/
Durham area violated the O3 NAAQS. Of these control measures, two
control measures produced the most significant decreases in VOC and
NOX emissions. One control measure is a reduction of fuel
volatility, as measured by the Reid Vapor Pressure (RVP), from 10.1 psi
in 1988 to 9.0 psi in 1990 and then to 7.8 psi in the summer of 1992.
As a result of the RVP reductions, there has been a reduction of
emissions of VOCs of more than 25% from 1988 to 1992 from gasoline
powered vehicles of all classes. The other control measure is the
improvement in tailpipe emissions associated with the Federal Motor
Vehicle Control Program (FMVCP). This program reduces VOC and NOX
emissions as newer, cleaner vehicles replace older, high emitting
vehicles. VOC emissions reductions are 20.9% from 1988 to 1990 and
NOX emissions reductions are 2.7% from 1988 to 1990.
In association with its emission inventory discussed below, the
State of North Carolina has demonstrated that actual enforceable
emission reductions are responsible for the recent air quality
improvement and that the VOC emissions in the base year are not
artificially low due to local economic downturn.
5. The Area Must Have a Fully Approved Maintenance Plan Pursuant to
Section 175A of the Act
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 North Carolina's
maintenance plan for the Raleigh/Durham area because EPA finds that the
State of North Carolina's submittal meets the requirements of section
175A.
A. Emissions Inventory--Base Year Inventory
On November 13, 1992, the State of North Carolina submitted
comprehensive inventories of VOC, NOX, and CO emissions from the
Raleigh/Durham area. The inventories included 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. The 1990 Base Year Emission Inventory for
the Raleigh/Durham area has been submitted to EPA in SIP Air Pollutant
Inventory Management Subsystem (SAMS) format.
The State of North Carolina submittal contains the detailed
inventory data and summaries by county and source category. This
comprehensive base year emissions inventory was submitted in the SAMS
format. Finally, this inventory was prepared in accordance with EPA
guidance. A summary of the base year and projected maintenance year
inventories are shown in the following three tables. Refer to the TSD
prepared for this notice for more in-depth details regarding the base
year inventory for the Raleigh/Durham area.

B. Demonstration of Maintenance--Projected Inventories
Total VOC, NOX, and CO emissions were projected from the 1990
base year out to 2004. These projected inventories were prepared in
accordance with EPA guidance. Refer to EPA's TSD prepared for this
notice for more in-depth details regarding the projected inventory for
the Raleigh/Durham area.
On January 12, 1994, the State of North Carolina submitted
supplemental projection inventories. The State recalculated growth
rates to include 1992 Vehicle Miles Traveled (VMT) data received in
late 1993 from the North Carolina Department of Transportation. The
projections indicate that VOC, NOx, and CO emissions remain under
the 1990 baseline emission inventory from 1990 through 2004. EPA
believes that the emissions projections demonstrate that the area will
continue to maintain the O3 NAAQS because this area achieved
attainment through VOC controls and reductions. The projected emission
inventories were submitted in the SAMS format.
C. Verification of Continued Attainment
Continued attainment of the O3 NAAQS in the Raleigh/Durham
area depends, in part, on the State of North Carolina's efforts toward
tracking indicators of continued attainment during the maintenance
period. The State of North Carolina's contingency plan is triggered by
two indicators, an air quality violation or the periodic emissions
inventory exceeding the baseline emission inventory by more than 10%.
As stated in the maintenance plan, the NCDEHNR will be developing these
periodic emissions inventories every three years beginning in 1996.
These periodic inventories will help to verify continued attainment.
Refer to the TSD prepared for this notice for a more complete
discussion of the indicators the State is tracking and the contingency
measures.
D. Contingency Plan
The level of VOC and NOx emissions in the Raleigh/Durham 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,
the State of North Carolina has provided contingency measures with a
schedule for implementation in the event of a future O3 air
quality problem. The plan contains a contingency to implement pre-
adopted additional control measures such as Reasonable Available
Control Technology (RACT) level control for not previously controlled
VOC sources, Stage II vapor control for gasoline dispensing facilities,
and new source permit requirements for VOC and NOx emissions to
include emission offsets, Lowest Achievable Emission Rate (LAER) level
control, and permit applicability. These pre-adopted additional
measures will be implemented within 45 days of the date the State
certifies to EPA that the air quality data which demonstrates a
violation of the O3 NAAQS is quality assured. The plan also
contains a secondary trigger that will apply where no actual violation
of the NAAQS has occurred. The secondary trigger is an exceedance of
the baseline emissions inventory by more than 10%. On the occurrence of
the secondary trigger, the State will commence, within 60 days of the
trigger, regulation development and adoption of measures amending the
State vehicle inspection and maintenance (I/M) program, extending
coverage of the I/M program, extending and/or lowering vapor pressure
limits for gasoline, extending geographic coverage of RACT controls,
transportation control measures, and RACT level control for NOx. A
complete description of these contingency measures and their triggers
can be found in the TSD prepared for this notice. EPA finds that the
contingency measures provided in the State of North Carolina submittal
meet the requirements of section 175A(d) of the CAA.
E. Subsequent Maintenance Plan Revisions
In accordance with section 175A(b) of the CAA, the State of North
Carolina 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 final action, EPA is approving the Raleigh/Durham O3
maintenance plan, including the 1990 base year emission inventory,
because it meets the requirements of section 175A. In addition, the EPA
is redesignating the Raleigh/Durham area to attainment for O3
because the State of North Carolina has demonstrated compliance with
the requirements of section 107(d)(3)(E) for redesignation. This action
stops the sanctions and federal implementation plan clocks that were
triggered for the Raleigh/Durham area by the January 15, 1993, findings
letter. Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
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.
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 of North Carolina 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 a finding of
nonimplementation (section 173(b) of the CAA) or in a SIP deficiency
call made pursuant to section 110(a)(2)(H) of the CAA.
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 businesses, small not-for-profit enterprises,
and government entities with jurisdiction over populations of less than
50,000.
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.
This action is being taken without prior proposal because the
changes are noncontroversial and EPA anticipates no significant
comments on them. The public should be advised that this action will be
effective June 17, 1994. If, however, notice is received by May 18,
1994 that someone wishes to submit adverse or critical comments, this
action will be withdrawn and two subsequent notices will be published
before the effective date. One will withdraw the final action and the
other will begin a new rulemaking by announcing a comment period.
Under section 307(b)(1) of the CAA, 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 June 17,
1994. 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 CAA, 42 U.S.C. 7607 (b)(2).)
This action has been classified as a Table 2 action by the Regional
Administrator under the procedures published in the Federal Register on
January 19, 1989, (54 FR 2214-2225) as revised by a Memorandum from
Michael H. Shapiro to Regional Administrators, dated October 4, 1993.
On January 6, 1989, the Office of Management and Budget (OMB) waived
Table 2 and 3 SIP revisions (54 FR 2222) from the requirements of
section 3 of Executive Order 12291 for two years. The U.S. EPA has
submitted a request for a permanent waiver for Table 2 and Table 3 SIP
revisions. OMB has agreed to continue the temporary waiver until such
time as it rules on EPA's request. This request continues in effect
under Executive Order 12866 which superseded Executive Order 12291 on
September 30, 1993.
Nothing in this action shall be construed as permitting or allowing
or establishing a precedent for any future request for a revision to
any state 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.
