ENVIRONMENTAL PROTECTION AGENCY
40 CFR Parts 52 and 81
[WA51-7124a; FRL-5613-3]
Approval and Promulgation of Implementation Plans and
Redesignation of Puget Sound, Washington for Air Quality Planning
Purposes: Ozone
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The EPA is announcing its determination that the Puget Sound
(parts of King, Pierce, and Snohomish Counties) Ozone Nonattainment
area has attained the public health-based National Ambient Air Quality
Standard (NAAQS) for ozone (O3). This determination is based upon
three years of complete, quality-assured, ambient air monitoring data
for the 1991 to 1993 ozone seasons that demonstrate that the ozone
NAAQS has been attained. The EPA is also approving the redesignation to
attainment of the Puget Sound Area and the associated maintenance plan.
DATES: This action will be effective November 25, 1996 unless adverse
or critical comments are received by October 28, 1996. If the effective
date is delayed, timely notice will be published in the Federal
Register.
ADDRESSES: Written comments should be addressed to: Montel Livingston,
SIP Manager, Office of Air Quality (OAQ-107), EPA, 1200 Sixth Avenue,
Seattle, Washington 98101.
FOR FURTHER INFORMATION CONTACT: Stephanie Cooper, Office of Air
Quality, EPA Region 10, 1200 6th Avenue, Seattle, WA 98101, (206) 553-
6917.
SUPPLEMENTARY INFORMATION:
I. Background
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) of the CAA, in conjunction with
the Governor of Washington, EPA designated the Puget Sound Area as
nonattainment because the area violated the ozone standard during the
period from 1989-1991. The Puget Sound Area, which includes lands
within the Puyallup, Tulalip, Muckleshoot, Stillaguamish, and Nisqually
Reservations, was classified as ``marginal'' under section 181(a)(1) of
the CAA.
The Puget Sound Area has ambient monitoring data that show no
violations of the ozone NAAQS during the period from 1991 to the
present. On January 28, 1993 the State of Washington submitted a State
Implementation Plan (SIP) for compliance with the ozone NAAQS. Public
hearings were held respectively in Vancouver, SeaTac, and Spokane on
November 9, 10, and 12, 1992. Also, the State submitted an Ozone
Maintenance Plan and Redesignation Request on March 4, 1996. A public
hearing was held in Seattle on October 26, 1995.
II. Review of the State Submittal
The Puget Sound redesignation request for the nonattainment areas
meets the five requirements of section 107(d)(3)(E) of the CAA for
redesignation to attainment. EPA also finds that information and
requirements provided in the WDOE redesignation request and maintenance
plan for the Puget Sound nonattainment area demonstrate that the
107(d)(3)(E) of the CAA requirements have been met for the affected
tribal lands which include portions of the Stillaguamish Reservation,
Nisqually Reservation, Tulalip Reservation, Puyallup Reservation and
Muckleshoot Reservation. The Agency has not determined whether it is
bound to follow the formal requirements of section 107(d)(3)(E) of the
CAA when taking such redesignation actions for tribal lands. The action
to redesignate tribal lands to attainment is being taken today without
answering that question because information submitted by WDOE satisfies
each required element for redesignation.
The following is a brief description of how each of the
requirements of section 107(d)(3)(E) of the CAA is met. 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.
A. The Area Must Have Attained the O3 NAAQS
The State of Washington's redesignation 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.
The most recent ambient air quality monitoring data for calendar year
1991 through calendar year 1995 show an expected exceedance rate of
less than 1.0 per year of the ozone NAAQS in the Puget Sound area.
Because the Puget Sound area has complete quality-assured data showing
no violations of the standard over the most recent consecutive three-
calendar-year period, the area has met the first statutory criterion of
attainment of the ozone NAAQS. There are four ambient O3
monitoring stations in the Puget Sound nonattainment area, and the
State of Washington has committed to continue monitoring this area in
accordance with 40 CFR part 58.
B. The Area Has Met All Applicable Requirements Under Section 110, and
Part D of the Act
1. Section 110 Requirements
Although section 110 was amended in 1990 (CAAA or the Act), the
Washington SIP approved by EPA for the ozone marginal nonattainment
areas 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.
2. Part D Requirements
Before the nonattainment areas may be redesignated to attainment,
they must have fulfilled the applicable requirements of part D of the
CAA. 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 non-classifiable. Subpart 2 of part D establishes
additional requirements for O3 nonattainment areas classified
under table 1 of section 181(a).
(a). Subpart 1 of Part D. The State of Washington currently has a
fully approved New Source Review (NSR) program which was last revised
and approved June 2, 1995 (60 FR 28726). Upon redesignation of the
Puget Sound area to attainment, the Prevention of Significant
Deterioration (PSD) provisions contained in part C of title I are
applicable. EPA's PSD regulations in 40 CFR 52.21 will apply to the
Puget Sound area.
Under section 176(c) of the CAA, States were required to submit
revisions to their SIPs that include criteria and procedures to ensure
that Federal actions conform to the air quality planning goals in the
applicable SIPs. The requirement to determine conformity applies to
transportation plans, programs and projects developed, funded or
approved under Title 23 U.S.C. of the Federal Transit Act
(``transportation conformity''), as well as all other Federal actions
(``general conformity''). Congress provided for the State revisions to
be submitted one year after the date of promulgation of final EPA
conformity regulations. EPA promulgated final transportation conformity
regulations on November 24, 1993 (58 FR 62188) and final general
[[Page 50439]]
conformity regulations on 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 40 CFR Sec. 51.396 of the transportation
conformity rule, the WDOE was 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, pursuant to 40 CFR 51.851 of the general conformity rule,
the WDOE was required to submit a SIP revision containing general
conformity criteria and procedures consistent with those established in
the Federal rule by December 1, 1994. The WDOE submitted its
transportation conformity SIP revision to EPA on December 1, 1995. This
SIP has not been fully approved by EPA. The WDOE has not submitted its
general conformity SIP revision.
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, the 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, EPA has modified 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. (See 61 FR 2918, January 30, 1996). Under this
policy, for the reasons just discussed, EPA believes that the ozone
redesignation request for the Puget Sound area may be approved
notwithstanding the lack of submitted and approved state transportation
and general conformity rules.
(b). Subpart 2 of Part D. 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 Puget Sound area (parts of King,
Pierce, and Snohomish Counties) was designated as marginal O3
nonattainment. Because this area is marginal, the area must meet the
requirements of 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.
(i) 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. As part of the redesignation request submitted on
March 4, 1996, WDOE submitted a base year 1993 emission inventory for
the Puget Sound area. With this notice, EPA is approving the base year
inventory for the Puget Sound area.
(ii) Reasonably Available Control Technology (RACT). The CAA also
amended section 182(a)(2)(A), in which Congress statutorily adopted the
requirement that O3 nonattainment areas fix their deficient
Reasonably Available Control Technology (RACT) rules for O3. Areas
designated nonattainment before amendment of the CAA and which retained
that designation and were classified as marginal or above as of
enactment are required to meet the RACT fix-up requirement. The Puget
Sound area was designated nonattainment after 1990, and therefore, this
area is not subject to the RACT fix-up requirement.
(iii) Emissions Statements. The CAA required that the SIP be
revised by November 15, 1992, to require stationary sources of oxides
of nitrogen (NOX) and VOCs to provide the state with a statement
showing actual emissions each year. The WDOE submitted an Emission
Statement program as part of its O3 SIP on January 28, 1993, and
EPA approved the program on November 14, 1994.
C. The Area Has a Fully Approved SIP Under Section 110(k) of the CAA
EPA has determined that Washington has a fully approvable O3
SIP under section 110(k) for the ozone marginal nonattainment areas,
which also meets the applicable requirements of section 110 and part D
as discussed above.
D. The Air Quality Improvement Must Be Permanent and Enforceable
Several control measures have been put into place since the
nonattainment area violated the O3 NAAQS. One 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. Additionally, in 1993 the state expanded and intensified its
vehicle inspection and maintenance (I/M) program. Implementation of
this control measure has led to additional reductions in emissions.
This I/M program meets EPA's low enhanced performance standard.
In association with the emission inventory discussed below, the
State of Washington has demonstrated that actual enforceable emission
reductions are responsible for the recent air quality improvement.
E. The Area Must Have a Fully Approved Maintenance Plan Pursuant to
Section 175A of the CAA
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 Washington's maintenance plan for
the Puget Sound marginal nonattainment area because EPA finds that the
submittal meets the requirements of section 175A.
[[Page 50440]]
1. Emissions Inventory--Base Year Inventory
Along with the submittal of the redesignation request and
maintenance plan, Washington submitted comprehensive O3 emission
inventories for the base year and subsequent years for the Puget Sound
area on March 4, 1996. The inventories included biogenic, area,
stationary, and mobile sources using 1993 as the base year for
calculations to demonstrate maintenance. The 1993 inventory is
considered representative of attainment conditions because the NAAQS
was not violated during that year.
The State of Washington submittal contains the detailed inventory
data and summaries by county and source category. This inventory was
compiled in accordance with EPA guidance. A summary of the base year
and projected maintenance year inventories are shown for VOCs and
NOX in the following tables.
2. Demonstration of Maintenance--Projected Inventories
On March 4, 1996, the State of Washington submitted the Central
Puget Sound Ozone Nonattainment Area 1993-2010 Emission Inventory
Projections. Total VOC, NOX, and CO emissions were projected from
the 1993 base year out to 2010. These projected inventories were
prepared in accordance with EPA guidance. Refer to EPA's Technical
Support Document (TSD) (located in docket WA51-7124) prepared for this
notice for more details regarding the projected inventory for the Puget
Sound area.

As indicated in the following table, an emissions decrease in VOCs
and NOX in the Puget Sound nonattainment area is projected
throughout the maintenance period. EPA believes that these emissions
projections demonstrate that the Puget Sound nonattainment area will
continue to maintain the O3 NAAQS.

3. Verification of Continued Attainment
Continued attainment of the O3 NAAQS in the marginal
nonattainment areas depends, in part, on the State of Washington's
efforts toward tracking indicators of continued attainment during the
maintenance period. On an annual basis the Department of Ecology will
analyze the most recent three consecutive years of ambient ozone data
to verify continued attainment of the NAAQS for ozone. Additionally, a
First Implementation Phase Report will be published in 1998 to
chronicle the results of in-use vehicle emissions projects and research
activities related to the Maintenance Plan.
4. Contingency Plan
The level of VOC and NOX emissions in the nonattainment area
will largely determine its ability to stay in compliance with the
O3 NAAQS in the future. Despite the State of Washington'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 Washington has provided contingency measures
with a schedule for implementation in the event of a future O3 air
quality problem. The plan contains two tiers of contingency measures.
The first tier involves improving the existing motor vehicle inspection
and maintenance (I/M) program (within the current statutory authority
of the Department of Ecology) to reduce VOC vehicle emissions. The I/M
improvements will be triggered if the ozone standard is exceeded three
times at any one permanent monitoring site over two consecutive
calendar years, or in the event of a quality assured ozone standard
violation. The measure will be implemented no later than June 15th of
the year following the three exceedances or the violation.
The second tier contingency measure is a mandatory reduction in
gasoline
[[Page 50441]]
volatility, which will decrease the emission of volatile organic
compounds. The measure would be triggered pending a measured ozone
violation. If triggered, the measure would require all gasoline made
available for sale in King, Pierce, and Snohomish Counties between June
15 and September 15 to have a Reid Vapor Pressure (RVP) of 7.8 psi. If
both triggers and hence both contingency measures are activated, the
Ozone Maintenance Plan will be amended to include one or more new
contingency measures.
EPA finds that the contingency measures provided in the State of
Washington's submittal meet the requirements of section 175A(d) of the
CAA.
5. Subsequent Maintenance Plans Revisions
In accordance with section 175A(b) of the CAA, the State of
Washington is required to submit a revised maintenance SIP eight years
after the marginal nonattainment areas redesignate to attainment. Such
a revised SIP will provide for an additional ten years maintenance.
III. Final Action
EPA is approving the Puget Sound nonattainment area's O3
maintenance plan because it meets the requirements of section 175A of
the CAA. The EPA is redesignating the Puget Sound O3 nonattainment
area to attainment for O3 because the State of Washington has
demonstrated compliance with the requirements of section 107(d)(3)(E)
of the CAA for redesignation. In addition, EPA, after consultation with
the affected tribal governments, is redesignating to attainment those
areas in the Puget Sound ozone nonattainment area that are located
within the Tulalip Reservation, the Stilliguamish Reservation, the
Puyallup Reservation, the Nisqually Reservation, and the Muckleshoot
Reservation. The Agency believes that the redesignation requirements
are effectively satisfied here because of information provided by WDOE
and requirements contained in the WDOE SIP and Maintenance Plan.
Additionally, EPA is approving the 1993 base year emission inventory
for the Puget Sound nonattainment area.
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 Washington 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 179(b) of the CAA) and in a SIP deficiency
call made pursuant to section 110(a)(2)(H) of the CAA.
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 November 25, 1996 unless, by October 28, 1996, 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 notice that will
withdraw the final action. All public comments received will 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 November 25, 1996.
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
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.
IV. Administrative Requirements
A. Executive Order 12866
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.
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.
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 any small entities affected. Moreover,
due to the nature of the federal-state relationship under the CAA,
preparation of a regulatory flexibility analysis would constitute
federal inquiry into the economic reasonableness of state action. The
CAA forbids EPA to base its actions concerning SIPs on such grounds.
Union Electric Co. versus E.P.A., 427 U.S. 246, 256-66 (S.Ct. 1976); 42
U.S.C. 7410(a)(2).
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. I
certify that the approval of the redesignation request will not affect
a substantial number of small entities.
C. Unfunded Mandates
Under Section 202 of the Unfunded Mandates Reform Act of 1995
(``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 approval action promulgated does not
include a
[[Page 50442]]
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 approves pre-existing
requirements under State or local law, and imposes no new Federal
requirements. Accordingly, no additional costs to State, local, or
tribal governments, or to the private sector, result from this action.
D. Submission to Congress and the General Accounting Office
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 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 November 25, 1996. 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), 42 U.S.C.
7607(b)(2).
