Approval and Promulgation of Implementation Plans; Idaho and Washington; Interstate Transport of Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

SUMMARY: EPA is approving the actions of the Idaho Department of Environmental Quality (IDEQ) and the Washington State Department of Ecology (Ecology) to address the provisions of Clean Air Act section 110(a)(2)(D)(i) for the 8-hour ozone and PM2.5National Ambient Air Quality Standards (NAAQS). These provisions require each state to submit a State Implementation Plan (SIP) revision that prohibits emissions that adversely affect another state's air quality through

[[Page 35016]]

interstate transport. IDEQ and Ecology have each adequately addressed the four distinct elements related to the impact of interstate transport of air pollutants for their states. These include prohibiting emissions that contribute significantly to nonattainment of the NAAQS in another state, interfere with maintenance of the NAAQS by another state, interfere with plans in another state to prevent significant deterioration of air quality, or interfere with efforts of another state to protect visibility.

DATES: This direct final rule will be effective August 27, 2007, without further notice, unless EPA receives adverse comment by July 26, 2007. If adverse comment is received, EPA will publish a timely withdrawal of the direct final rule in the Federal Register informing the public that the rule will not take effect.

   1. Background of Submittal

      EPA is approving IDEQ's and Ecology's SIP revisions to address the requirements of Clean Air Act (CAA) section 110(a)(2)(D)(i). This CAA section requires each state to submit a SIP that prohibits emissions that could adversely affect another state, addressing four key elements. The SIP must prevent sources in the state from emitting pollutants in amounts which will: (1) Contribute significantly to nonattainment of the NAAQS in another state, (2) interfere with maintenance of the NAAQS by another state, (3) interfere with plans in another state to prevent significant deterioration of air quality, or (4) interfere with efforts of another state to protect visibility.

      EPA issued guidance on August 15, 2006, entitled ``Guidance for State Implementation Plan (SIP) Submissions to Meet Current Outstanding Obligations Under Section 110(a)(2)(D)(i) for the 8-Hour Ozone and PM2.5National Ambient Air Quality Standards,'' relating to SIP submissions to meet the requirements of CAA section 110(a)(2)(D)(i). As discussed below, Idaho's and Washington's analyses of their respective SIPs with respect to the statutory requirements of CAA section 110(a)(2)(D)(i) are consistent with the guidance. The discussion below covers how Idaho and Washington have addressed the four key requirements of CAA section 110(a)(2)(D)(i).

   2. How Idaho's Submittal Addresses the Provisions of Clean Air Act Section 110(a)(2)(D)(i)

      IDEQ addressed the first two elements of CAA section 110(a)(2)(D)(i) by submitting a technical demonstration supporting the conclusion that emissions from Idaho do not significantly contribute to nonattainment or interfere with maintenance of the 8-hour ozone and PM2.5NAAQS in another state. IDEQ relied on analysis by EPA that determined that it was reasonable to exclude the western United States, including Idaho, from the Clean Air Interstate Rule (CAIR), 70 FR 25162 (May 12, 2005). In the proposal for CAIR, EPA determined that because of geographical, meteorological, and topological factors, PM2.5and 8-hour ozone nonattainment problems are not likely to be affected significantly by pollution transported across these state's boundaries. See 69 FR 4566, 4581 (January 30, 2004).

      IDEQ also relied on information on the nearest nonattainment areas. For PM2.5, the closest nonattainment area is 25 miles away in Libby, Montana. 70 FR 944, 986 (January 5, 2005). IDEQ noted that the Technical Support Document (TSD) for the PM2.5 designation of the Libby area contains a description of the nonattainment area and sources. The Libby TSD states that PM2.5levels in the Libby, Montana area are localized due to topography and meteorological factors.

      For ozone, the closest nonattainment area to Idaho is Las Vegas, Nevada. Las Vegas is over 400 miles away. See 69 FR 23858, 23919 (April 30, 2004). IDEQ noted that the supporting documentation for the designation of this nonattainment area demonstrates

      [[Page 35017]]

      that the Las Vegas, Nevada area is geologically and topologically separate from surrounding areas. Based on this and other information provided by IDEQ in its SIP submittal, EPA believes the state has sufficiently demonstrated that emissions from Idaho do not significantly contribute to nonattainment or interfere with maintenance of the NAAQS in another state. Additional supporting information can be found in IDEQ's submittal included in the docket.

      The third element IDEQ addressed is prevention of significant deterioration (PSD). For 8-hour ozone, the state has met the obligation by confirming that major sources in the state are currently subject to PSD programs that implement the 8-hour ozone standard and that the state is working on adopting any relevant requirements of the Phase II ozone implementation rule. For PM2.5, IDEQ confirmed that the state's PSD program is being implemented in accordance with EPA's interim guidance calling for the use of PM10as a surrogate for PM2.5for the purposes of PSD review.

      The fourth element IDEQ addressed is protection of visibility. EPA's regional haze regulations, 64 FR 35714 (July 1, 1999), require states to submit regional haze SIPS to EPA by December 17, 2007. Since Idaho has not yet completed or submitted its regional haze SIP, it is not possible at this time for the State of Idaho to determine whether Idaho interferes with measures to protect visibility in the applicable SIP of another state.

   3. How Washington's Submittal Addresses the Provisions of Clean Air Act Section 110(a)(2)(D)(i)

      Ecology addressed the first two elements of CAA section 110(a)(2(D)(i) by submitting a technical demonstration supporting the conclusion that emissions from Washington do not significantly contribute to nonattainment or interfere with maintenance of the 8-hour ozone and PM2.5NAAQS in another state. Ecology relied on analysis by EPA that determined that it was reasonable to exclude the western United States, including Washington, from CAIR. As discussed in the proposal for CAIR, EPA determined that because of geographical, meteorological, and topological factors, PM2.5and 8-hour ozone nonattainment problems are not likely to be affected significantly by pollution transported across these State's boundaries. See 69 FR at 4581.

      Ecology also relied on information on the nearest nonattainment areas. For PM2.5, the closest nonattainment area is Libby, Montana. 70 FR at 986. Libby is over 150 miles away from Spokane, the nearest major city in Washington. Ecology noted that the TSD for the PM2.5designation of the Libby area contains a description of the nonattainment area and sources. The Libby TSD states that PM2.5levels in the Libby, Montana area are localized due to topography and meteorological factors.

      For ozone, the closest nonattainment area to Washington is the San Francisco Bay area in California. See 69 FR at 23887. San Francisco is over 600 miles away from Vancouver, the closest major urban area in Washington. Ecology noted that the supporting documentation for the designation of the San Francisco Bay nonattainment area contains information showing that the San Francisco airshed is separate from areas to the north.

      Ecology also discussed the Portland-Vancouver Interstate Ozone area. The Portland-Vancouver Interstate Ozone area comprises Portland, Oregon and Vancouver, Washington. The area was a maintenance area for the 1-hour ozone standard. It has been meeting the 8-hour ozone NAAQS since the standard was promulgated in 1997. Ecology explains that the Southwest Clean Air Agency (SWCAA), the local CAA planning agency for the Vancouver area, and the Oregon Department of Environmental Quality (ODEQ) worked together on modeling that demonstrates that the Portland- Vancouver area will continue to attain the 8-hour ozone NAAQS through 2015. Both SWCAA and Oregon have developed 110(a)(1) maintenance plans for the 8-hour ozone NAAQS based on the modeling to meet EPA implementation requirements. The modeling also demonstrates as part of the 110 (a)(l) plan that the Salem-Keizer area to the south of Portland will continue to maintain the 8-hour ozone NAAQS through 2015. Ecology notes that both Washington and Oregon will submit the plans to EPA for approval this year. The draft plans are available on the SWCAA and ODEQ websites.

      Based on this and other information provided by Washington in its SIP submittal, EPA believes the state has sufficiently demonstrated that emissions from Washington do not significantly contribute to nonattainment or interfere with maintenance of the NAAQS in another state. Additional supporting information can be found in the state's SIP submittal included in the docket.

      The third element Ecology addressed is PSD. For 8-hour ozone, the state has met the obligation by confirming that major sources in the state are currently subject to PSD programs that implement the 8-hour ozone standard and that the state is working on adopting any relevant requirements of the Phase II ozone implementation rule. For PM2.5, Ecology confirmed that the state's PSD program is being implemented in accordance with EPA's interim guidance calling for the use of PM10as a surrogate for PM2.5for the purposes of PSD review.

      The fourth element Ecology addressed is protection of visibility. EPA's regional haze regulations require states to submit regional haze SIPS to EPA by December 17, 2007. Since Washington has not yet completed or submitted its regional haze SIP, it is not possible at this time for the State of Washington to determine whether Washington interferes with measures to protect visibility in the applicable SIP of another state.

   4. Statutory and Executive Order Reviews

      Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a ``significant regulatory action'' and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this action will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this action approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it 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).

      This action also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various

      [[Page 35018]]

      levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. This action also is not subject to Executive Order 13045, ``Protection of Children from Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997), because it approves a state rule implementing a Federal standard.

      In reviewing state submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a state submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a state submission, to use VCS in place of a state submission that otherwise satisfies the provisions of the CAA. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

      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 rule 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 27, 2007. 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).)
