[Federal Register Volume 83, Number 125 (Thursday, June 28, 2018)] [Proposed Rules] [Pages 30380-30382] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-13861] ======================================================================= ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 52 [EPA-R10-OAR-2018-0060; FRL-9979-99--Region 10] Air Plan Approval; Washington; Interstate Transport Requirements for the 2012 PM2.5 NAAQS AGENCY: Environmental Protection Agency (EPA). ACTION: Proposed rule. ----------------------------------------------------------------------- SUMMARY: The Clean Air Act (CAA) requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting emissions that will have certain adverse air quality effects in other states. On February 7, 2018, the State of Washington made a submission to the Environmental Protection Agency (EPA) to address these requirements. The EPA is proposing to approve the submission as meeting the requirement that each SIP contain adequate provisions to prohibit emissions that will contribute significantly to nonattainment or interfere with maintenance of the 2012 annual fine particulate matter (PM2.5 ) national ambient air quality standard (NAAQS) in any other state.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,'' ``us,'' or ``our'' is used, we mean the EPA. This supplementary information section is arranged as follows: Table of Contents I. What is the background of this SIP submission? II. What guidance or information is the EPA using to evaluate this SIP submission? III. The EPA's Review IV. What action is the EPA taking? V. Statutory and Executive Order Reviews I. What is the background of this SIP submission? This rulemaking addresses a submission from the Washington Department of Ecology (Ecology) assessing interstate transport requirements for the 2012 annual PM2.5 NAAQS. The requirement for states to make a SIP submission of this type arises from section 110(a)(1) of the CAA. Pursuant to section 110(a)(1), states must submit within 3 years (or such shorter period as the Administrator may prescribe) after the promulgation of a national primary ambient air quality standard (or any revision thereof), a plan that provides for the implementation, maintenance, and enforcement of such NAAQS. The statute directly imposes on states the duty to make these SIP submissions, and the requirement to make the submissions is not conditioned upon the EPA taking any action other than promulgating a new or revised NAAQS. Section 110(a)(2) includes a list of specific elements that ``[e]ach such plan'' submission must address. The EPA commonly refers to such state plans as ``infrastructure SIPs.'' Specifically, this rulemaking addresses the requirements under CAA section 110(a)(2)(D)(i)(I), otherwise known as the ``good neighbor'' provision, which requires SIPs to contain adequate provisions to prohibit emissions that will contribute significantly to nonattainment or interfere with maintenance of the NAAQS in any other state. II. What guidance or information is the EPA using to evaluate this SIP submission? The most recent relevant document was a memorandum published on March 17, 2016, titled ``Information on the Interstate Transport ``Good [[Page 30381]] Neighbor'' Provision for the 2012 Fine Particulate Matter National Ambient Air Quality Standards under Clean Air Act Section 110(a)(2)(D)(i)(I)'' (memorandum). The memorandum describes the EPA's past approach to addressing interstate transport, and provides the EPA's general review of relevant modeling data and air quality projections as they relate to the 2012 annual PM2.5 NAAQS. The memorandum provides information relevant to the EPA Regional office review of the CAA section 110(a)(2)(D)(i)(I) ``good neighbor'' provision in infrastructure SIPs with respect to the 2012 annual PM2.5 NAAQS. This rulemaking considers information provided in that memorandum. The memorandum also provides states and the EPA Regional offices with future year annual PM2.5 design values for monitors in the United States based on quality assured and certified ambient monitoring data and air quality modeling. The memorandum describes how these projected potential design values can be used to help determine which monitors should be further evaluated to potentially address whether emissions from other states significantly contribute to nonattainment or interfere with maintenance of the 2012 annual PM2.5 NAAQS at those sites. The memorandum explains that the pertinent year for evaluating air quality for purposes of addressing interstate transport for the 2012 PM2.5 NAAQS is 2021, the attainment deadline for 2012 PM2.5 NAAQS nonattainment areas classified as Moderate. Based on this approach, the potential receptors are outlined in the memorandum. Most of the potential receptors are in California, located in the San Joaquin Valley or South Coast nonattainment areas. However, there is also one potential receptor in Shoshone County, Idaho, and one potential receptor in Allegheny County, Pennsylvania. The memorandum also indicates that for certain states with incomplete ambient monitoring data, additional information including the latest available data should be analyzed to determine whether there are potential downwind air quality problems that may be impacted by transported emissions. This rulemaking considers analysis in Washington's submission, as well as additional analysis conducted by the EPA during review of its submission. For more information on how we conducted our analysis, please see the technical support document (TSD) included in the docket for this action. III. The EPA's Review This rulemaking proposes action on Washington's February 7, 2018, SIP submission addressing the good neighbor provision requirements of CAA section 110(a)(2)(D)(i)(I). State plans must address specific requirements of the good neighbor provisions (commonly referred to as ``prongs''), including: --Prohibiting any source or other type of emissions activity in one state from contributing significantly to nonattainment of the NAAQS in another state (prong one); and --Prohibiting any source or other type of emissions activity in one state from interfering with maintenance of the NAAQS in another state (prong two). The EPA has developed a consistent framework for addressing the prong one and two interstate transport requirements with respect to the PM2.5 NAAQS in several previous federal rulemakings. The four basic steps of that framework include: (1) Identifying downwind receptors that are expected to have problems attaining or maintaining the relevant NAAQS; (2) identifying which upwind states contribute to these identified problems in amounts sufficient to warrant further review and analysis; (3) for states identified as contributing to downwind air quality problems, identifying upwind emissions reductions necessary to prevent an upwind state from significantly contributing to nonattainment or interfering with maintenance of the relevant NAAQS downwind; and (4) for states that are found to have emissions that significantly contribute to nonattainment or interfere with maintenance of the relevant NAAQS downwind, reducing the identified upwind emissions through adoption of permanent and enforceable measures. This framework was applied with respect to PM2.5 in the Cross- State Air Pollution Rule (CSAPR), designed to address both the 1997 and 2006 PM2.5 standards, as well as the 1997 ozone standard.\1\ --------------------------------------------------------------------------- \1\ Washington was not part of the CSAPR rulemaking. The EPA approved the Washington SIP as meeting the CAA section 110(a)(2)(D)(i)(I) requirements for the 1997 ozone and 1997 PM2.5 NAAQS on January 13, 2009 (74 FR 1591) and the 2006 PM2.5 NAAQS on July 30, 2015 (80 FR 45429). --------------------------------------------------------------------------- In its submission, Ecology generally mirrored the framework established by the EPA. Specifically: (1) Ecology reviewed past and current air quality nationwide to identify potential downwind receptors that may have problems attaining or maintaining the 2012 PM2.5 NAAQS; (2) Ecology identified those western receptors from the broader nationwide list that may be impacted by Washington for further review and analysis; (3) Ecology then reviewed air quality reports, modeling results, designation letters, designation technical support documents, and available attainment plans to determine if emissions from Washington may impact these specific areas; (4) Lastly, Ecology conducted its own independent Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) back trajectory modeling for Shoshone County, Idaho to support the state's conclusion that sources in Washington are not significantly contributing to this receptor, or interfering with maintenance of this receptor. From this analysis, Ecology concluded that Washington does not significantly contribute to nonattainment or interfere with maintenance of the 2012 PM2.5 NAAQS in any other state. As discussed in the TSD for this action, we came to the same conclusion as the state. In our evaluation, potential downwind nonattainment and maintenance receptors were identified in other states. The EPA evaluated these potential receptors to determine first if, based on review of relevant data and other information, there would be downwind nonattainment or maintenance problems, and if so, whether Washington contributes to such problems in these areas. After reviewing air quality reports, modeling results, designation letters, designation technical support documents, attainment plans and other information for these areas, we find there is no contribution sufficient to warrant additional SIP measures. Therefore, we are proposing to approve the Washington SIP as meeting CAA section 110(a)(2)(i)(I) interstate transport requirements for the 2012 PM2.5 NAAQS. IV. What action is the EPA taking? The EPA is proposing to approve Ecology's February 7, 2018, submission certifying that the Washington SIP is sufficient to meet the interstate transport requirements of CAA section 110(a)(2)(D)(i)(I), specifically prongs one and two, as set forth above. The EPA is requesting comments on the proposed approval. V. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the [[Page 30382]] EPA's role is to approve state choices, provided that they meet the criteria of the CAA. 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866; 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 CAA; 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, the SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
