Approval and Promulgation of Air Quality Implementation Plans;
State of Utah; Salt Lake and Davis Counties Ozone Redesignation to
Attainment, Designation of Areas for Air Quality Planning Purposes,
Approval of Related Elements, Approval of Partial NOX RACT
Exemption, and Approval of Weber County I/M Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: On May 23, 1997, EPA published a notice of proposed rulemaking
(NPR) that proposed to approve the State of Utah's request to
redesignate the Salt Lake and Davis Counties (SLDC) moderate ozone
nonattainment area to attainment. In that NPR, EPA also proposed to
approve the maintenance plan for the SLDC area, and the following
related State Implementation Plan (SIP) elements: the 1990 base year
emissions inventory, Reasonably Available Control Technology (RACT) for
Volatile Organic Compounds (VOC), Nitrogen Oxides (NOX) RACT
for Kennecott's Utah Power Plant and for the Pacificorp Gadsby Power
Plant, and the Basic Inspection and Maintenance (I/M) and Improved I/M
provisions for Salt Lake and Davis Counties. EPA also proposed to
approve a partial NOX RACT exemption request. In this final
rulemaking, EPA is approving the redesignation request, the maintenance
plan, the various related SIP elements, and the partial NOX
RACT exemption request. In the May 23, 1997, NPR, EPA also proposed to
give limited approval to the State's generic VOC RACT and generic
NOX RACT rules and to approve the I/M provisions for Weber
County. In this rulemaking, EPA is giving limited

[[Page 38214]]

approval to the VOC and NOX generic RACT rules and is
approving the I/M provisions for Weber County.

EFFECTIVE DATE: August 18, 1997.

ADDRESSES: Copies of the State's redesignation request, maintenance
plan and other documents relevant to this action are available for

SUPPLEMENTARY INFORMATION:

I. Background

On November 15, 1990, the Clean Air Act Amendments of 1990 were
enacted (Pub. L. 101-549, 104 Stat. 2399, codified at 42 U.S.C. 7401-
7671q). Under section 107(d)(1)(C) of the CAA, EPA designated the SLDC
area as nonattainment for ozone because the area had been designated as
nonattainment before November 15, 1990. The SLDC area was classified as
a moderate nonattainment area (see section 181 of the CAA for further
information regarding classifications and attainment dates for ozone
nonattainment areas).
Under the Clean Air Act (CAA), designations can be changed if
sufficient data are available to warrant such changes and if certain
other requirements are met. See CAA section 107(d)(3)(D). Section
107(d)(3)(E) of the CAA provides that the Administrator may not
promulgate a redesignation of a nonattainment area to attainment
unless:
(i) the Administrator determines that the area has attained the
national ambient air quality standard;
(ii) the Administrator has fully approved the applicable
implementation plan for the area under CAA section 110(k);
(iii) the Administrator determines that the improvement in air
quality is due to permanent and enforceable reductions in emissions
resulting from implementation of the applicable implementation plan and
applicable Federal air pollutant control regulations and other
permanent and enforceable reductions;
(iv) the Administrator has fully approved a maintenance plan for
the area as meeting the requirements of CAA section 175A; and,
(v) the State containing such area has met all requirements
applicable to the area under section 110 and part D of the CAA.
EPA has reviewed the State's redesignation request, maintenance
plan, related SIP elements, and the partial NOX RACT
exemption request. EPA has also considered all public comments
submitted in response to the NPR for this action (EPA only received one
comment letter from the Utah Mining Association which was in support of
the NPR). EPA has determined that all required SIP elements, including
the maintenance plan, have either been approved previously or will be
fully approved with this action, that the area has attained the ozone
National Ambient Air Quality Standard (NAAQS), and that the improvement
in air quality is due to permanent and enforceable reductions in
emissions resulting from the implementation of the applicable
implementation plan and applicable Federal air pollutant control
regulations and other permanent and enforceable reductions. Thus, the
five criteria in section 107(d)(3)(E) of the Clean Air Act (CAA) have
been met and approval of the redesignation request is warranted.
Detailed descriptions of how the section 107(d)(3)(E) requirements have
been met are provided in the May 23, 1997, NPR for this action (62 FR
28396) and will not be repeated here.
In addition to the SIP elements related to the redesignation
request, EPA also proposed action in the May 23, 1997, NPR on three
unrelated SIP elements. First, EPA proposed to give limited approval to
the State's generic VOC and NOX RACT rules. In the NPR, EPA
noted deficiencies in these rules that prevent full approval, and thus,
EPA is only giving limited approval to these rules for their
strengthening effect, not as meeting the CAA's requirements for VOC and
NOX RACT. Second, EPA proposed to approve I/M provisions for
Weber County and is now fully approving these I/M provisions. A
detailed description of EPA's rationale for these actions is contained
in the May 23, 1997, NPR for this action (62 FR 28396).

II. Final Action

A. In this action, EPA is approving the following:
1. The SLDC redesignation request--EPA is approving the Governor's
November 12, 1993, request to redesignate the SLDC ozone nonattainment
area to attainment.
2. The SLDC maintenance plan--EPA is approving the maintenance plan
that the Governor submitted on February 19, 1997 (``maintenance
plan''). EPA notes that a key aspect of the maintenance plan is its
implications with respect to the conformity regulations. These
regulations require a demonstration that emissions from the
transportation plan and Transportation Improvement Program are
consistent with the emissions budget in the SIP (40 CFR 93.118 and
93.119). The emissions budget is defined as the level of mobile source
emissions relied upon in the attainment or maintenance demonstration to
maintain compliance with the NAAQS in the nonattainment area. The
rule's requirements and EPA's policy on emissions budgets are found in
the Preamble to the transportation conformity rule (58 FR 62193-62196)
and in the sections of the rule referenced above.
The maintenance plan defines emissions budgets for each year
between 1994 and 2007, and for 2015 and 2020. The 1994-2007 emissions
budgets are based on the maintenance plan's emission inventory
projections, while the 2015 and 2020 budgets are based on EKMA
modeling. The maintenance plan lists budgets for Salt Lake County and
Davis County separately, and for the entire nonattainment area (both
Counties combined). The plan provides that the metropolitan planning
organization (Wasatch Front Regional Council) may demonstrate
conformity with the budgets for each County individually or for the
entire nonattainment area at its option. The plan also identifies a
safety margin (called the ``emissions credit'') for each year, which is
the difference between total emissions from all sources in the
attainment year and in each future year. The plan provides that this
safety margin may be used for conformity purposes if authorized by the
Utah Air Quality Board.
3. The 1990 SLDC ozone base year emissions inventory--EPA is
approving the 1990 SLDC ozone base year emissions inventory that the
Governor submitted on January 13, 1995, (with corrections submitted on
April 20, 1995, by Russell Roberts, Director, Utah Division of Air
Quality).
4. VOC RACT--EPA is approving the State's VOC RACT requirements as
presented in specific sections of the maintenance plan (described
below) and

[[Page 38215]]

as reflected in the following State Approval Orders (AO):
(a) Hill Air Force Base (HAFB) AO DAQE-163-96 dated February 9,
1996, HAFB AO DAQE-1134-95 dated December 7, 1995, HAFB AO DAQE-860-95

Service Station dated July 12, 1979, HAFB AO for Construction dated
June 27, 1978, and the Olympia Sales Company AO DAQE-300-95 dated April
13, 1995.
(b) VOC RACT, as described in the maintenance plan, was addressed
for the Amoco, Chevron, Crysen, Flying J, and Phillips refineries
through the Governor's submittals of VOC RACT rules on May 4, 1990 and
July 25, 1991, as approved by EPA on June 26, 1992 (57 FR 28621).
5. NOX RACT--EPA is approving the State's NOX
RACT requirements as reflected in the following State Approval Orders
(AO):
(a) Pacificorp Gadsby Power Plant--AO: DAQE-0063-94, dated February
3, 1994.
(b) Kennecott Utah Copper Utah Power Plant--AO: DAQE-433-94, dated
May 27, 1994.
6. Basic Inspection and Maintenance (I/M) for Salt Lake and Davis
Counties--EPA is approving the Basic I/M provisions for Salt Lake and
Davis Counties that the Governor submitted on February 19, 1997.
7. Improved I/M for Salt Lake and Davis Counties--EPA is approving
the Improved I/M provisions for Salt Lake and Davis Counties that the
Governor submitted on February 19, 1997.
8. Partial NOX RACT Exemption Request--EPA is approving
the Partial NOX RACT Exemption Request for the SLDC area as
was submitted by Ursula Trueman, Director, Utah Division of Air Quality
on May 2, 1997. It is important to note that EPA is only approving an
exemption from the NOX RACT requirements for those major
stationary sources of NOX in the SLDC nonattainment area
other than the Pacificorp Gadsby Power Plant and the Kennecott Utah
Copper Utah Power Plant. EPA is not approving an exemption from the
NOX NSR requirements, NOX conformity
requirements, or the motor vehicle I/M requirements related to
NOX. Furthermore, EPA notes that NOX limits for
some or all of the major stationary sources of NOX other
than the Pacificorp Gadsby and Kennecott Utah Copper Utah Power Plants
are necessary for the SLDC nonattainment area to demonstrate
maintenance of the ozone NAAQS through 2007 (2020 for conformity
purposes).
9. Revisions to UACR R307-1-3.3.3.C, a portion of ``Control of
Installations'' and revisions to UACR R307-3.5.3.B(1), a portion of
``Emission Statement Inventory,'' both as submitted by the Governor on
February 19, 1997.
B. Unrelated to the SLDC ozone redesignation request, EPA is also
taking the following actions:
1. EPA is approving the Weber County Basic I/M provisions as
submitted by the Governor on February 19, 1997.
2. EPA is granting limited approval of revisions to UACR R307-14-1
``Requirements for Ozone Nonattainment Areas and Davis and Salt Lake
Counties'' as submitted by the Governor on February 6, 1996. UACR R307-
14-1 requires RACT for existing major sources of VOC and NOX
for which no specific emission limits or other control requirements
have been established in R307-14. This generic RACT rule strengthens
the SIP, but does not meet all the CAA requirements for RACT. Thus, EPA
is approving this rule for its strengthening effect only. For a full
discussion of the reasons EPA is unable to fully approve the revisions
to UACR R307-14-1, please refer to the May 23, 1997, NPR for this
action (62 FR 28396, 28399-28400, 28404).
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any State Implementation Plan. Each request for revision to
any 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.

III. 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 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 sections 107(d)(3)(D)
and (E) of the CAA does not impose any new requirements on small
entities. Redesignation to attainment is an action that affects the
status of a geographical area and does not impose any regulatory
requirements on sources. Therefore, I certify that the approval of the
redesignation request will not affect a substantial number of small
entities.
SIP approvals under section 110 and subchapter I, part D of the
Clean Air Act 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 any small entities
affected. Moreover, due to the nature of the Federal-State relationship
under the CAA, preparation of a flexibility analysis would constitute
Federal inquiry into the economic reasonableness of State action. The
Clean Air Act forbids EPA to base its actions concerning SIPs on such
grounds. Union Electric Co. v. U.S. EPA, 427 U.S. 246, 255-66 (1976);
42 U.S.C. 7410(a)(2).
Approvals of NOX exemption requests under section 182(f)
of the CAA do not create any new requirements. Therefore, I certify
that approval of the State's partial NOX RACT exemption
request will not have a significant impact on any small entities
affected.

C. Unfunded Mandates

Under Section 202 of the Unfunded Mandates Reform Act of 1995

[[Page 38216]]

(``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 determined that the proposed action does not include a
Federal mandate that may result in estimated costs of $100 million or
more to either State, local, or tribal governments in the aggregate or
to the private sector. This Federal action will approve a redesignation
to attainment, pre-existing requirements under State or local law, and
an exemption from requirements otherwise imposed under the CAA; this
action will impose no new requirements. Accordingly, no additional
costs to State, local, or tribal governments, or to the private sector,
will result from this action.

D. Submission to Congress and the General Accounting Office

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

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 15, 1997. 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).)

3. New Sec. 52.2350 is added to read as follows:

Sec. 52.2350 Emission inventories.

The Governor of the State of Utah submitted the 1990 base year
emission inventory of ozone precursors, which are volatile organic
compounds, nitrogen oxides, and carbon monoxide, for the Salt Lake and
Davis Counties ozone nonattainment area on January 13, 1995, as a
revision to the State Implementation Plan (SIP). This inventory
addresses emissions from point, area, non-road, on-road mobile, and
biogenic sources. This Governor's submittal was followed by the
submittal of corrections to the inventory, on April 20, 1995, from
Russell Roberts, Director, Division of Air Quality, Utah Department of
Environmental Quality. The ozone maintenance plan for Salt Lake and
Davis Counties that the Governor submitted on February 19, 1997,
incorporates by reference the corrected 1990 base year ozone emission
inventory as background material. The 1990 ozone base year emission
inventory requirement of section 182(a)(1) of the Clean Air Act, as
amended in 1990, has been satisfied for the Salt Lake and Davis
Counties area.
4. New Sec. 52.2351 is added to read as follows:

Sec. 52.2351 Area-wide nitrogen oxides (NOX) exemption.

On May 2, 1997, Ursula Trueman, Director, Division of Air Quality,
Utah Department of Environmental Quality, submitted, on behalf of the
State of Utah and pursuant to section 182(f)(2)(A) of the Clean Air Act
as amended in 1990, a section 182(f)(2) NOX Reasonably
Available Control Technology (RACT) exemption request for major
stationary sources of NOX in the Salt Lake and Davis
Counties ozone nonattainment area other than the Pacificorp Gadsby and
Kennecott Utah Copper Utah Power Plants. The exemption request was
based on ambient air quality monitoring data which demonstrated that
the ozone National Ambient Air Quality Standard (NAAQS) had been
attained in the Salt Lake and Davis Counties ozone nonattainment area
for the years 1990 through 1996. EPA approved this NOX RACT
exemption request on July 2, 1997.
