Throughout this document, wherever “we,” “us,” or “our” is used, it means the EPA.

I. Background

On March 24, 2020, we proposed to approve updates to certain NWCAA regulations currently in the SIP, remove obsolete regulations, and approve a subset of updated Ecology regulations to apply in NWCAA's jurisdiction (85 FR Start Printed Page 3615516599). The reasons for our proposed approval were stated in the proposed rule and will not be re-stated here. The public comment period for our proposed action ended on April 23, 2020. We received no comments. Therefore, we are finalizing our action as proposed.

II. Final Action

A. Regulations Approved and Incorporated by Reference Into the SIP

The EPA is approving and incorporating by reference into the Washington SIP at 40 CFR 52.2470(c)—Table 5—Additional Regulations Approved for the Northwest Clean Air Agency (NWCAA) Jurisdiction, the following NWCAA regulatory sections (effective date):

  • 100 (8/21/2005), 101 (8/21/2005), 102 (8/21/2005), 200 (5/12/2019), 300 (5/12/2019), 305 (5/12/2019), 320 (5/12/2019), and 321 (05/12/2019).

The EPA is also approving and incorporating by reference the following Chapter 173-400 Washington Administrative Code (WAC) sections submitted for approval to apply within NWCAA's jurisdiction (effective date):

  • 173-400-020 (12/29/2012), 173-400-025 (9/16/2018), 173-400-030 (9/16/2018), 173-400-050 (09/16/2018), 173-400-060 (11/25/2018), 173-400-091 (4/1/2011), 173-400-111 (7/1/2016), 173-400-112 (12/29/2012), 173-400-113 (12/29/2012), 173-400-117 (12/29/2012), 173-400-118 (12/29/2012), 173-400-131 (04/1/2011), 173-400-136 (12/29/2012), 173-400-151 (2/10/2005), 173-400-171 (9/16/2018), 173-400-200 (2/10/2005), 173-400-800 (4/1/2011), 173-400-810 (7/1/2016), 173-400-820 (12/29/2012), 173-400-830 (7/1/2016), 173-400-840 (7/1/2016), 173-400-850 (7/1/2016), and 173-400-860 (4/1/2011).

Please see the amendatory text for more detailed information about the provisions submitted and approved in this action, including local agency corollaries which replace certain Chapter 173-400 WAC provisions and exclusions to our approval.

B. Approved But Not Incorporated by Reference Regulations

In addition to the regulations approved and incorporated by reference above in section II of this preamble, the EPA reviews and approves state and local clean air agency submissions to ensure they provide adequate enforcement authority and other general authority to implement and enforce the SIP. However, regulations describing such agency enforcement and other general authority are generally not incorporated by reference so as to avoid potential conflict with the EPA's independent authorities. Therefore, we are approving the following updates to NWCAA's general provisions for inclusion in 40 CFR 52.2470(e), Table 1—Approved but Not Incorporated by Reference Regulations: 103, 105, 110, 111, 112, 113, 114, 120, 123, 124, 131, 132, 133, 134, 135, and 303. We are also removing prior references to these provisions from 40 CFR 52.2470(c) because they are now included in 40 CFR 52.2470(e).

C. Regulations To Remove From the SIP

As discussed in the proposal for this action, we are removing from the SIP sections: 104, 106, 122, 130, 140, 145, 301, 302, 310, 322, 323, 400, 401, 410, 420, 422, and 424. We are also removing from the SIP any formerly approved WAC provisions which are replaced by local agency corollaries for facilities or actions subject to NWCAA's jurisdiction.

D. Scope of Proposed Action

This revision to the SIP applies specifically to the NWCAA jurisdiction incorporated into the SIP at 40 CFR 52.2470(c), Table 5. As discussed in our proposal, local air agency jurisdiction in Washington is generally defined on a geographic basis; however, there are exceptions. By statute, NWCAA does not have authority for sources under the jurisdiction of the Energy Facilities Site Evaluation Council (EFSEC). See Revised Code of Washington Chapter 80.50. Under the applicability provisions of WAC 173-405-012, 173-410-012, and 173-415-012, NWCAA also does not have jurisdiction for kraft pulp mills, sulfite pulping mills, and primary aluminum plants. For these sources, Ecology retains statewide, direct jurisdiction. Ecology and EFSEC also retain statewide, direct jurisdiction for issuing Prevention of Significant Deterioration (PSD) permits. Therefore, the EPA is not approving into 40 CFR 52.2470(c), Table 5, those provisions of Chapter 173-400 WAC related to the PSD program. Specifically, these provisions are WAC 173-400-116 and WAC 173-400-700 through 173-400-750, which the EPA has already approved as applying state-wide under 40 CFR 52.2470(c), Tables 2 and 3.

Also, as described in our proposal for this action, jurisdiction to implement the visibility permitting program contained in WAC 173-400-117 varies depending on the situation. Ecology and EFSEC retain authority to implement WAC 173-400-117 as it relates to PSD permits. However, for facilities subject to major nonattainment new source review (NSR) under the applicability provisions of WAC 173-400-800, we are approving NWCAA's implementation of those parts of WAC 173-400-117 as they relate to major nonattainment NSR permits. Therefore, we are modifying the visibility protection Federal Implementation Plan contained in 40 CFR 52.2498 to reflect the approval of WAC 173-400-117 as it applies to implementation of the major nonattainment NSR program in NWCAA's jurisdiction.

Lastly, this SIP revision is not approved to apply on any Indian reservation land in Washington and is also not approved to apply in any other area where the 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).

III. Incorporation by Reference

In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, we are finalizing the incorporation by reference as described in sections II.A. and II.C. of this preamble. The EPA has made, and will continue to make, these materials generally available through and at the EPA Region 10 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). Therefore, these materials have been approved by the EPA for inclusion in the SIP, have been incorporated by reference by the EPA into that plan, are fully federally-enforceable under sections 110 and 113 of the CAA as of the effective date of the final rulemaking of the EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.[1]

IV. Statutory and Executive Order Review

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 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 Start Printed Page 36156those 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 it does not address technical standards; and
  • Does not provide the 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).

The SIP is not approved to apply on any Indian reservation land in Washington except as specifically noted below and is also not approved to apply in any other area where the 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).

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. The 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 CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by August 14, 2020. 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)).
