SUPPLEMENTARY INFORMATION:

On June 8, 2018, the West Virginia Department of Environmental Protection (WVDEP) submitted a formal revision to its SIP pertaining to amendments of Legislative Rule, 45CSR8—Ambient Air Quality Standards. The SIP revision consists of revising the effective date of the incorporation by reference of the NAAQS and the associated monitoring reference and equivalent methods.

I. Summary of SIP Revision

This SIP revision is required by WVDEP in order to update the State's incorporation by reference of the primary and secondary NAAQS and the ambient air monitoring reference and equivalent methods, found in 40 CFR parts 50 and 53, respectively. Currently, 45CSR8 incorporates by reference 40 CFR parts 50 and 53 as effective on June 1, 2016. Since that date, EPA retained the standard for lead and made a technical correction to the particulate standard. See 81 FR 71906 and 82 FR 14325, respectively. EPA also designated one new ambient air monitoring reference method for measuring concentrations of sulfur dioxide, four new ambient air monitoring equivalent methods for measuring concentrations of fine and coarse particulate matter (PM_2.5 and PM_10, respectively), and two new equivalent methods for measuring concentrations of nitrogen dioxide (NO₂) in ambient air.

The amendments to the legislative rule include the following changes: To section 45-8-1 (General), the filing, effective, and incorporation by reference dates are changed to reflect the update of the legislative rule; to section 45-8-3 (Adoption of Standards), the effective dates for the incorporation by reference of the primary and secondary NAAQS and the ambient air monitoring reference and equivalent methods are changed. The filing and effective dates of the legislative rule were updated to March 22, 2018 and June 1, 2018 respectively. The effective date of the incorporation by reference of 40 CFR parts 50 and 53 changed from June 1, 2016 to June 1, 2017.

II. Proposed Action

EPA is proposing to approve the West Virginia SIP revision updating the date of incorporation by reference, which was submitted on June 8, 2018. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

III. Incorporation by Reference

In this proposed rule, EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference 45CSR8, as effective on June 1, 2018. EPA has made, and will continue to make, these materials generally available through http://www.regulations.gov and at the EPA Region III Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information).

IV. 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, 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 proposed 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, this proposed rule, updating the effective date of West Virginia's 45CSR8, 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.
