I. Background On March 8, 2021, we proposed to approve the source-specific SIP revision submitted by Ecology for the TransAlta Centralia Generation Plant 86 FR
13256. The reasons for our proposed approval were stated in the proposed rulemaking and will not be re-stated here. The public comment period for our proposed action ended on April 7, 2021. We received no comments.
Therefore, we are finalizing our action as proposed.
II. Final Action The EPA is approving, and incorporating by reference into the Washington SIP, BART Order 6426 for the TransAlta Centralia Generation Plant, state effective July 29, 2020.1 The EPA is also removing from incorporation by reference the previous BART Order 6426 for the TransAlta Centralia Generation Plant, State effective December 13, 2011.2 The EPA
has determined that the changes improve the operation of pollution controls at the plant and are consistent with regional haze and other Clean Air Act CAA requirements.
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 changes to the incorporation by reference as described in section II of this preamble.
The EPA has made, and will continue to make, these materials generally available through https
www.regulations.gov 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 rule of the EPAs approval, and will be incorporated by reference in the next update to the SIP compilation.3

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. 7410k; 40 CFR 52.02a.
Thus, in reviewing SIP submissions, the EPAs 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;
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. 1044;
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 12d 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
