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: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: On August 9, 1991, the North Carolina Department of
Environmental Management (NCDEM), submitted a maintenance plan and a
request to redesignate the Charlotte area from nonattainment to
attainment for carbon monoxide (CO). The Charlotte CO nonattainment
area consists only of Mecklenburg County. Subsequently, NCDEM submitted
supplemental material to the Charlotte submittal on October 7, 1994.
Included with this package was a request to redesignate the Raleigh/
Durham area from nonattainment to attainment for CO. The Raleigh/Durham
CO nonattainment area consists of Durham and Wake Counties. Under the
Clean Air Act as amended in 1990 (CAA), designations can be revised if
sufficient data is available to warrant such revisions. In this action,
EPA is approving the North Carolina request because it meets the
maintenance plan and redesignation requirements set forth in the CAA.
DATES: This action will be effective September 18, 1995, unless
critical or adverse comments are received by September 1, 1995. If the
effective date is delayed, timely notice will be published in the
Federal Register.
ADDRESSES: Written comments should be sent to Ben Franco, at the EPA
Regional office 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.

SUPPLEMENTARY INFORMATION: In a March 15, 1991, letter to the EPA
Region 4 Administrator, the Governor of North Carolina recommended the
areas of Raleigh/Durham and Charlotte be designated as nonattainment
for CO, as required by section 107(d)(1)(A) of the 1990 CAA (Pub. L.
101-549, 104 Stat. 2399, codified at 42 U.S.C. 7401-767lql). The cities
were designated nonattainment and classified as ``moderate,'' except
for Charlotte which was classified as ``not classified,'' under the
provisions outlined in sections 186 and 187 of the CAA (See 56 FR 56694
(Nov. 6, 1991) and 57 FR 56762 (Nov. 30, 1992), codified at 40 CFR part
81, Sec. 81.334). The National Ambient Air Quality Standard (NAAQS) for
CO is 9.5 ppm. CO nonattainment areas can be classified as moderate or
serious, based on their design values. Since Raleigh/Durham had a
design value of 10.9 ppm (based on 1988 and 1989 data), the area was
classified as moderate. The Charlotte area was a pre-1990 nonattainment
area and was designated by operation of law. However, the Charlotte
area was classified as ``not classified'' because it had a design value
of 8.4 ppm (based on 1988 and 1989 data), which is below the 9.5 ppm.
The CAA established an attainment date of December 31, 1995, for all
moderate CO areas. ``Not Classified'' areas, such as Charlotte, must
attain by November 15, 1995.
The Raleigh/Durham and Charlotte areas have ambient air quality
monitoring data showing attainment of the CO NAAQS from 1990 through
1993. The areas continued to monitor attainment in 1994 and 1995.
Therefore, in an effort to comply with the CAA and to ensure continued
attainment of the NAAQS, on August 9, 1991, and October 7, 1994, the
State of North Carolina submitted CO redesignation requests and
maintenance plans for the Charlotte and Raleigh/Durham areas,
respectively. The October 7, 1994, submittal included a revision of the
1991 Charlotte redesignation request. The request for redesignation
submittal and maintenance plan was approved by NCEMC on September 8,
1994. North Carolina submitted evidence that a public hearing was held
on March 28 and March 30, 1994.
The 1990 CAA Amendments revised section 107(d)(3)(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 applicable requirements under section 110
and Part D of the CAA;
3. The area must have a fully approved state implementation plan
under section 110(k) of 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.
On November 12, 1991, and December 8, 1994, Region 4 determined the
Charlotte and Raleigh/Durham submittal, respectively, constituted a
complete redesignation request under the general completeness criteria
of 40 CFR 51, appendix V, sections 2.1 and 2.2.
The North Carolina redesignation request for the Raleigh/Durham and
Charlotte areas meet 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 CO NAAQS
The North Carolina requests are based on an analysis of quality
assured CO air monitoring data which is relevant to the maintenance
plan and to the redesignation requests. The ambient air CO monitoring
data for calendar year 1991 through calendar year 1993 shows no
violations of the CO NAAQS in the Raleigh/Durham and Charlotte areas.
The most recent ambient CO data for the calendar year 1994 continue to
show no violations in the Raleigh/Durham and Charlotte areas. Because
the Raleigh/Durham and Charlotte areas have complete quality assured
data showing no more than one exceedance of the standard per year over
at least two consecutive years, the area has met the first statutory
criterion of attainment of the CO NAAQS (40 CFR 50.9 and Appendix C1).
North Carolina 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
The 1990 CAA Amendments, 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.
A. Section 110 Requirements
Section 110 was amended by the 1990 Amendments. The North Carolina
SIP meets the requirements of amended section 110(a)(2). The State
implemented an Oxygenated Fuel program in the area of Raleigh/Durham
during the 1992 and 1993 winter seasons. The Charlotte area was not
required to implement an Oxygenated Fuels program. EPA has reviewed the
SIP and determined that it is consistent with the requirements of
amended section 110(a)(2).
B. Part D Requirements
Before Raleigh/Durham and Charlotte may be redesignated to
attainment, the applicable requirements of Part D must be fulfilled.
Subpart I of Part D sets forth the basic nonattainment requirements
applicable to all nonattainment areas, classified as well as
nonclassifiable. Subpart 3 of Part D establishes additional
requirements for nonattainment areas classified under section 186(a).
The Raleigh/Durham area was classified as moderate (See 40 CFR 81.334).
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 the requirements of Subpart 3 of Part D,
which became due on or before August 9, 1991, and October 7, 1994, the
dates the State submitted complete redesignation requests for Charlotte
and Raleigh/Durham, respectively. EPA interprets, according to section
107(d)(3)(E)(v) to mean that, for a redesignation request to be
approved, the State must have met all requirements that become
applicable to the subject area prior to or at time of the submission of
the redesignation request. Requirements of the CAA due subsequent to
the submission of the redesignation request will continue to be
applicable to the area (See section 175A(c)) until the redesignation
request is approved. If the redesignation is
[[Page 39260]]
disapproved, the State remains obligated to fulfill those requirements.
B1. Subpart 1 of Part D
Section 172(c) of Subpart 1 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. Because the Raleigh/Durham area was designated as a
new CO nonattainment area on June 6, 1992, the section 172(c)
requirements are due by June 6, 1995. Therefore, the submission by
North Carolina of New Source Review and contingency measures required
under 172(c) are not yet due. To the extent the moderate CO
nonattainment area requirements of section 187(a) supersede the section
172(c) requirements, as is the case with emission inventories, North
Carolina has complied with those requirements.
B2. Subpart 1 of Part D
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 SIP. The requirement to determine conformity applies to
general and transportation plans, programs and projects developed,
funded or approved under Title 23 U.S.C. or the Federal Transit Act
(``transportation conformity''). Section 176 further provides that the
conformity revisions to be submitted by States 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 the EPA
conformity regulations would establish a submittal date (see 57 FR
13498, 13557 (April 16, 1992)).
EPA promulgated final conformity regulations on November 24, 1993
(58 FR 62188)) and November 30, 1993 (58 FR 63214). These conformity
rules require that the 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 section 51.396 of the transportation conformity rule and section
51.851 of the general conformity rule, the State of North Carolina 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, North Carolina is
required to submit a SIP revision containing general conformity
criteria and procedures consistent with those established in the
Federal rule by December 1, 1994. On March 3, 1995, NCDEM submitted
general and transportation conformity regulations.
B3. Subpart 3 of Part D
Under section 187(a) areas designated nonattainment for CO under
the amended CAA and classified as moderate were required to meet
several requirements by November 15, 1992. Consequently, these
requirements are pertinent only for the Raleigh/Durham area. These
requirements included a 1990 Emission Inventory, an Inspection and
Maintenance Program (I/M), and an Oxygenated Fuel Program. EPA has
reviewed and is approving in this notice, North Carolina's 1990 Base
Year Emission Inventory. Section 211(m) further required North Carolina
to submit an oxygenated fuels regulation for the Raleigh/Durham area.
NCDEM submitted a complete Oxygenated Fuel SIP on November 20, 1992,
which was approved by EPA on June 30, 1994. On August 5, 1994, NCDEM
submitted a complete I/M SIP, which was approved by EPA on June 2,
1995. Therefore, all Subpart 3 requirements that were applicable at the
time the State submitted its redesignation request have been met.
3. Fully Approved SIP Under Section 110(k) of the CAA
Based on the approval of provisions under the preamended CAA and
EPA's approval of SIP revisions under the 1990 Amendments, EPA has
determined that the Raleigh/Durham and Charlotte areas have 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 North Carolina SIP
control strategy for the Charlotte nonattainment area, satisfied that
the rules and the emission reductions achieved as a result of those
rules were enforceable. The control measures due to an I/M program
generates annual CO reductions of about 12 percent. The fleet turnover
under the Federal Motor Vehicle Emission Control Program produced
annual CO emission reductions of 6 percent. There were additional
emission reductions of 19 to 21 percent in the Raleigh/Durham area due
to the implementation of an Oxygenated Fuels program during the winter
seasons of 1992 and 1993.
In association with its emission inventory discussed below, the
State of North Carolina has demonstrated that actual enforceable
emission reductions are responsible for the air quality improvement and
that the CO emissions in the base year are not artificially low due to
local economic downturn. EPA finds that the combination of existing EPA
approved SIP and federal measures contribute to the permanence and
enforceability of reduction in ambient CO 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 North Carolina's maintenance
plan for the Raleigh/Durham and Charlotte areas because EPA finds that
North Carolina's submittals meet the requirements of section 175A.
A. Emissions Inventory--Base Year Inventory
On November 16, 1992, the State of North Carolina submitted a
comprehensive inventory of CO emissions of the Raleigh/Durham and
Charlotte areas. The inventory includes emissions from area,
stationary, and mobile sources using 1990 as the base year for
calculations.
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 National Emission Data System
format. The inventory was prepared in accordance with EPA guidance. It
also contains summary tables of the 1990 and 1991 base years and
projections to the year 2005 for the Charlotte and Raleigh/Durham
areas, respectively.

----------------------------------------------------------------------------------------------------------------
B. Demonstration of Maintenance--Projected Inventories
Total CO emissions were projected from 1990 base year out to 2005
for the Charlotte area, and from 1991 out to 2005 for the Raleigh/
Durham area. These projected inventories were prepared in accordance
with EPA guidance. The difference between Raleigh/Durham's 1990 Base
Year Inventory area sources and 1991 Base Year were due to different
methodologies. For 1991, additional data was included in the
calculation of the emissions. North Carolina will reduce the minimum
oxygen content for the Oxygenated Fuel program in Raleigh/Durham. The
projections show that calculated CO emissions, assuming a less
stringent oxygenated fuels program, are not expected to exceed the
level of the base year inventory during this time period. Therefore,
based on the results of Mobile5A modeling, it is anticipated that
Raleigh/Durham will maintain the CO standard with this program. It is
also anticipated that the Charlotte area will maintain the CO NAAQS
over the projected years. In case of an air quality problem, an
Oxygenated Fuel program will be implemented in Charlotte, as a
contingency measure.
C. Verification of Continued Attainment
Continued attainment of the CO NAAQS in the Raleigh/Durham and
Charlotte areas depend, in part, on the State's efforts toward tracking
indicators of continued attainment during the maintenance period. The
State has committed to submit periodic inventories of CO emissions
every three years.
D. Contingency Plan
The level of CO emissions in the Raleigh/Durham and Charlotte areas
will largely determine their ability to stay in compliance with the
NAAQS in the future. Section 175A(d) of the CAA requires that the
contingency provisions include a requirement that the State implement
all measures contained in the SIP prior to redesignation. Therefore,
North Carolina has provided contingency measures with a schedule for
implementation in the event of a future CO air quality problem. The
plan contains triggering mechanisms to determine when contingency
measures are needed. The Raleigh/Durham and Charlotte contingency
plans, primary trigger will be a violation of the CO NAAQS. A secondary
trigger will be activated within 30 days of the State finding either:
(1) The periodic emissions inventory exceeds the base inventory by 10
percent or more, or (2) a monitored air quality exceedance pattern
indicates that an actual CO NAAQS violation may be imminent. A pattern
will be deemed to indicate an imminent violation if (a) one exceedance
of the standard per year has been monitored at a single monitor for two
successive years and those exceedances are at least greater than 20
percent above the standard (i.e., 10.8 ppm or above) or (b) the
monitored air quality exceedance pattern otherwise suggests that a CO
NAAQS violation is likely. Within 45 days of the trigger, the State
will activate the pre-adopted regulations discussed below to become
effective at the beginning of the next CO season. When other measures
are needed to ensure that a future violation of the CO NAAQS does not
occur, the State will complete the adoption process within one year of
the secondary trigger. In case of a primary or secondary trigger, NCDEM
will implement one or a combination of the following contingency
measures: implementing either a 2.7 or 3.1 percent Oxygenated Fuel
program, expanding the I/M program coverage, enhanced I/M,
transportation control measures, or employee commute options program.
EPA finds that the contingency measures provided in the State submittal
meet the requirements of section 175A(d) of the CAA.
[[Page 39262]]
E. 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
EPA is approving the Raleigh/Durham and Charlotte CO maintenance
plans because they meet the requirements set forth in section 175A of
the CAA. EPA is also approving the 1990 emissions inventory as
complying with the requirements of section 172(c)(3) and 187(a)(1). In
addition, the Agency is approving the requests and redesignating the
Raleigh/Durham and Charlotte CO areas to attainment, because the State
has demonstrated compliance with the requirements of section
107(d)(3)(E) for redesignation.
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 September 18, 1995, unless, by September 1, 1995, 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 September 18, 1995.
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 CO SIP is designed to satisfy the requirements of Part D of the
CAA and to provide for attainment and maintenance of the CO NAAQS. This
final redesignation should not be interpreted as authorizing the State
to delete, alter, or rescind any of the CO emission limitations and
restrictions contained in the approved CO SIP. Changes to CO SIP
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 179(a) of the CAA) and in a SIP deficiency
call made pursuant to sections 110(a)(2)(H) and 110(k)(2) 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.
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, it does not have any
economic impact on any small entities. 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. Accordingly, I certify that the
approval of the redesignation request will not have an impact on any
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 175A and
section 187(a)(1) of the Clean Air Act. The rules and commitments
approved in this action may bind State, local and tribal governments to
perform certain actions and also may ultimately lead to the private
sector being required to certain duties. To the extent that the rules
and commitments being approved by this action will impose or lead to
the imposition of any mandate upon the State, local or tribal
governments either as the owner or operator of a source or as a mandate
upon the private sector, EPA's action will impose no new requirements
under State law; such sources are already subject to these requirements
under State law. Accordingly, no additional costs to State, local, or
tribal governments, or to the private sector, results 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.
