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.

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).
