ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R10-OAR-2007-0998; FRL-8684-1]

 
Approval and Promulgation of State Implementation Plans: 
Washington; Vancouver Air Quality Maintenance Area Second 10-Year 
Carbon Monoxide Maintenance Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is taking direct final action to approve a State 
Implementation Plan (SIP) revision submitted by the State of 
Washington. The Washington State Department of Ecology submitted the 
Vancouver Air Quality Maintenance Area Second 10-year Carbon Monoxide 
Maintenance Plan on April 25, 2007. In accordance with the requirements 
of the Federal Clean Air Act (the Act), EPA is approving Washington's 
revision because the State adequately demonstrates that the Vancouver 
Air Quality Maintenance Area will maintain air quality standards for 
carbon monoxide (CO) through the year 2016.

DATES: This rule is effective on August 26, 2008, without further 
notice, unless EPA receives adverse comment by July 28, 2008. If EPA 
receives adverse comment, we will publish a timely withdrawal in the 
Federal Register informing the public that the rule will not take 
effect.

I. General Information

A. What Should I Consider as I Prepare My Comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
RME, regulations.gov or e-mail. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as 
CBI and then identify electronically within the disk or CD ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information 
claimed as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 Code of Federal Regulations (CFR) part 2.
    2. Tips for Preparing Your Comments. When submitting comments, 
remember to:
    i. Identify the rulemaking by docket number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. Follow directions--The Agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
    vi. Provide specific examples to illustrate your concerns, and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period 
deadline identified.

II. What Is the Purpose of This Action?

    EPA is taking direct final action to approve the Second 10-year CO 
Maintenance Plan for the Vancouver, Washington Air Quality Maintenance 
Area. Vancouver attained the CO national ambient air quality standards 
(NAAQS) in 1996 and has not violated the standard since 1990. The 
second 10-year CO maintenance plan submitted by the state of Washington 
is designed to keep the Vancouver area in attainment for the CO 
standard for a second ten-year period beyond redesignation.

III. What Is the Background for This Action?

    Under section 107(d)(1)(C) of the Act, any area designated before 
the date of enactment of the Clean Air Act Amendments of 1990 (CAAA) 
was to be designated upon enactment by operation of law. Under section 
107(d)(1)(A) of the Act, States were required by 120 days after 
enactment of the CAAA, to submit lists designating all areas of the 
State as attainment, unclassifiable, or nonattainment.
    Accordingly, on March 15, 1991, letters were submitted by the 
governors of Washington and Oregon to the EPA Region 10 Administrator 
recommending the Vancouver and Portland areas, respectively, be 
designated as nonattainment for CO. On November 6, 1991 (56 FR 56694) 
the areas were designated by EPA as nonattainment for CO and classified 
as ``moderate'' with design values less than or equal to 12.7 parts per 
million (ppm) under the provisions outlined in sections 186 and 187 of 
the Act. On September 29, 1995 (60 FR 50423) EPA divided the Portland-
Vancouver area into separate nonattainment areas for each state.
    The State of Washington, following the requirements of the Act, 
prepared and submitted revisions to the Washington SIP that first 
included an attainment plan, and then developed a plan to demonstrate 
maintenance of the standard for a 10-year period beyond the statutory 
attainment date. EPA published approval of a redesignation request to 
attainment and the first 10-year maintenance plan on October 21, 1996 
(61 FR 54560). The first 10-year CO maintenance plan included a 
commitment for periodic review of the plan and submission of the second 
10-year maintenance plan. The State of Washington submitted a second 
10-year maintenance plan to EPA on April 25, 2007.
    The national 8-hour CO ambient standard is attained when the daily 
average 8-hour CO concentration of 9.0 ppm is not exceeded more than 
once a year. Since the redesignation of the Vancouver area to 
attainment for CO on October 21, 1996, the second highest concentration 
in any calendar year measured by the approved monitoring network was 
6.7 ppm, which is less than 9.0 ppm. Therefore the area is attaining 
the CO NAAQS.
    In addition, areas that can demonstrate design values at or below 
7.65 ppm (85 percent of exceedance levels of the CO NAAQS) for 8 
consecutive quarters may use a Limited Maintenance Plan option. The 
current 8-hour CO design value for the Vancouver area is 4.8 ppm based 
on 2004-2005 data. The State of Washington has opted to develop a 
Limited Maintenance Plan to fulfill the Vancouver Area second 10-year 
maintenance period required by the Act.

IV. How Have the Public and Stakeholders Been Involved in This 
Rulemaking Process?

    Section 110(a)(2) of the Act requires that each SIP revision be 
adopted after reasonable notice and public hearing. This must occur 
prior to the revision being submitted by a State to us. The state of 
Washington held a public hearing on March 1, 2007 in Vancouver, 
Washington. A notice of public hearing

[[Page 36441]]

was published in The Columbian on January 29, 2007. A notice was also 
published in the Washington State Register on February 7, 2007. This 
SIP revision became State effective on April 9, 2007, and was submitted 
by the Governor's designee to us on April 25, 2007. EPA has evaluated 
the State's submittal and determined that the State met the 
requirements for reasonable notice and public hearing under section 
110(a)(2) of the Act.

V. Evaluation of Washington's Submittal

    EPA has reviewed the State's revised CO maintenance plan for the 
Vancouver air quality maintenance. This revision provides the second 
10-year update to the maintenance plan for the area, as required by 
section 175A(b) of the Act. The following is a summary of the 
requirements and EPA's evaluation of how each requirement is met.

A. Base Year Emissions Inventory

    The plan must contain an attainment year emissions inventory to 
identify a level of emissions in the area which is sufficient to attain 
the CO NAAQS. The Vancouver CO second 10-year maintenance plan contains 
an emissions inventory for the base year 2002 that is consistent with 
EPA's most recent guidance on maintenance plan emission inventories. 
The emissions inventory is a list, by source, of the air contaminants 
directly emitted into the Vancouver CO area. The data in the emissions 
inventory is based on calculations and is developed using emission 
factors, which is a method for converting source activity levels into 
an estimate of emissions contributions for those sources. Because 
violations of the CO NAAQS are most like to occur on winter weekdays, 
the inventory prepared is in a ``typical winter day'' format. The table 
below shows the pounds of CO emitted per winter day in 2002 by source 
category.

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

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

B. Demonstration of Maintenance

    The maintenance plan demonstration requirement is considered to be 
satisfied for areas using the Limited Maintenance Plan option, which 
are required to demonstrate design values at or below 7.65 ppm (85 
percent of exceedance levels of the CO NAAQS) for 8 consecutive 
quarters. The State of Washington has opted to develop a Limited 
Maintenance Plan to fulfill the Vancouver Area second 10-year 
maintenance period required by the Act.
    With the Limited Maintenance Plan option, there is no requirement 
to project emissions of air quality over the maintenance period. EPA 
believes that if the area begins the maintenance period at, or below, 
85 percent of the level of the CO 8-hour NAAQS, the applicability of 
prevention of significant deterioration requirements, the control 
measures already in the SIP, and Federal measures, should provide 
adequate assurance of maintenance over the 10-year maintenance period. 
The last monitored violation of the CO NAAQS in Vancouver occurred in 
1990 and monitored CO levels have been steadily in decline ever since. 
The current 8-hour CO design value for the Vancouver CO area is 4.8 ppm 
based on 2004-2005 data, which is below the limited maintenance plan 
requirement of 7.65 ppm. Therefore, the Vancouver area has adequately 
demonstrated that it will maintain the CO NAAQS into the future.

C. Monitoring Network and Verification of Continued Attainment

    To verify the attainment status of the area over the maintenance 
period, the maintenance plan should contain provisions for continued 
operation of an appropriate, EPA-approved monitoring network in 
accordance with 50 CFR part 58. The State of Washington has an approved 
monitoring network that includes the Vancouver area. The monitoring 
network was most recently approved by EPA on November 16, 2007. In 
2006, the Southwest Clean Air Agency requested permission to remove the 
CO monitor at the Atlas and Cox site in Vancouver and EPA concurred 
that monitoring could be discontinued at the site. The State is 
continuing to verify attainment by conducting a triennial review of CO 
emissions from the countywide emissions inventory.

D. Contingency Plan

    Section 175A(d) of the Act requires that a maintenance plan include 
contingency provisions. The Vancouver Area CO Maintenance Plan contains 
a tiered level of response should the triennial emission inventory show 
that annual county-wide on road mobile emissions have increased over 
2005 levels. The contingency plan calls for analysis of appropriate 
emission reduction measures and their implementation.

VI. Transportation and General Conformity

    Transportation conformity is required by section 176(c) of the 
Clean Air Act. EPA's conformity rule requires that transportation 
plans, programs, and projects that are funded under 23 U.S.C. or the 
Federal Transit Act conform to SIPs. Conformity to a SIP means that 
transportation activities will not produce new air quality violations, 
worsen existing violations, or delay timely attainment of the NAAQS.
    The transportation conformity rule (40 CFR parts 51 and 93) and the 
general conformity rule (40 CFR parts 51 and 93) apply to nonattainment 
areas and maintenance areas covered by an approved maintenance plan. 
Under either conformity rule, an acceptable method of demonstrating 
that a Federal action conforms to the applicable SIP is to demonstrate 
that expected emissions from the planned action are consistent with the 
emissions budget for the area.
    While EPA's Limited Maintenance Plan option does not exempt an area 
from the need to affirm conformity, it explains that the area may 
demonstrate conformity without submitting an emissions budget. Under 
the Limited Maintenance Plan option, emissions budgets are treated as 
essentially not constraining for the length of the maintenance period 
because it is unreasonable to expect that the qualifying areas would 
experience so much growth in that period that a violation of the CO 
NAAQS would result. Similarly, Federal actions subject to the general 
conformity rule could be considered to satisfy the ``budget test'' 
specified in section 93.158(a)(5)(i)(A) for the same reasons that the 
budgets are essentially considered to be unlimited.
1. Transportation Conformity
    While areas with maintenance plans approved under the Limited 
Maintenance Plan option are not subject to the budget test, the areas 
remain subject to other transportation conformity requirements of 40 
CFR part 93, subpart A. Thus, the metropolitan planning organization 
(MPO) in the area or the State must document and ensure that:
    a. Transportation plans and projects provide for timely 
implementation of SIP transportation control measures in accordance 
with 40 CFR 93.113;
    b. Transportation plans and projects comply with the fiscal 
constraint element per 40 CFR 93.108;

[[Page 36442]]

    c. The MPO's interagency consultation procedures meet applicable 
requirements of 40 CFR 93.105;
    d. Conformity of transportation plans is determined no less 
frequently than every four years, and conformity of plan amendments and 
transportation projects is demonstrated in accordance with the timing 
requirements specified in 40 CFR 93.104;
    e. The latest planning assumptions and emissions model are used as 
set forth in 40 CFR 93.110 and 40 CFR 93.111;
    f. Projects do not cause or contribute to any new localized carbon 
monoxide or particulate matter violations, in accordance with 
procedures specified in 40 CFR 93.123; and
    g. Project sponsors and/or operators provide written commitments as 
specified in 40 CFR 93.125.
    EPA meets at least annually with the Washington Department of 
Ecology, the Southwest Clean Air Agency, the Federal Highway 
Administration, the Southwest Washington Regional Transportation 
Council, and the Washington Department of Transportation to review 
documentation and the Transportation Improvement Plan for the Vancouver 
area and determine if the area is meeting the transportation conformity 
requirements under 40 CFR part 93. Vancouver is currently meeting the 
requirements under 40 CFR part 93, subpart A.
    On November 19, 2007, EPA posted a notice finding the Vancouver CO 
second 10-year maintenance plan adequate for transportation conformity 
purposes. (See 72 FR 65019.)

VII. Final Action

    In accordance with the requirements of the Federal Clean Air Act 
(the Act), EPA is approving this revision to the State Implementation 
Plan (SIP) because the State adequately demonstrates that the Vancouver 
Air Quality Maintenance Area will maintain air quality standards for CO 
through the year 2016. EPA is publishing this action without prior 
proposal because the Agency views this as a noncontroversial amendment 
and anticipates no adverse comments. However, in the proposed rules 
section of this Federal Register publication, EPA is publishing a 
separate document that will serve as the proposal to approve the SIP 
revision should adverse comments be filed. This rule will be effective 
August 26, 2008 without further notice unless the Agency receives 
adverse comments by July 28, 2008.
    If EPA receives such comments, then EPA will publish a timely 
withdrawal of the direct final rule informing the public that the rule 
will not take effect. All public comments received will then be 
addressed in a subsequent final rule based on the proposed rule. The 
EPA will not institute a second comment period on this rule. Any 
parties interested in commenting on this rule should do so at this 
time. If no such comments are received, the public is advised that this 
rule will be effective on August 26, 2008 and no further action will be 
taken on the proposed rule.

VIII. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely approves state law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    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 August 26, 2008. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action 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).)
