E8-6915. Delegation of New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants for the States of Arizona and Nevada

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

EPA is updating the Code of Federal Regulations (CFR) delegation tables to reflect the current delegation status of the New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAPs) in Arizona and Nevada. These updates were proposed in the Federal Register on June 21, 2007.

DATES:

Effective Date: This rule is effective on May 5, 2008.

ADDRESSES:

EPA established docket number EPA-R09-OAR-2006-1014 for this action. The index to the docket is available electronically at http://www.regulations.gov and in hard copy at EPA, Region IX, 75 Hawthorne Street, San Francisco, California. While all documents in the docket are listed in the index, some information may be publicly available only at the hard copy location (e.g., copyrighted material), and some may not be publicly available in either location (e.g., confidential business information).

I. Background

On June 21, 2007, EPA proposed to update the delegation tables in the Code of Federal Regulations, Title 40 (40 CFR) Parts 60 and 61, to allow easier access by the public to the status of delegations in Arizona and Nevada jurisdictions (see 72 FR 34209). The updated delegation tables include the delegations approved in response to recent requests, as well as those previously granted. The tables are shown at the end of this document.

II. Public Comment and EPA Response

EPA's proposed action provided a 30-day public comment period. During this period, we received one comment from the State of Nevada's Division of Environmental Protection (NDEP). NDEP noted that it requested delegation of Appendix B, Performance Specifications, of 40 CFR Part 60 (Appendix B), and that EPA approved this request by letter dated January 12, 2007. However, EPA's proposed rulemaking did not include Appendix B in the “Delegation Status for NSPS for Nevada” table. NDEP requested that EPA add Appendix B to Nevada's NSPS delegation status table.

Appendix B was included in our approval letter of January 12, 2007 in error. Appendices to 40 CFR Parts 60 and 61 are not performance standards and are not delegable under Clean Air Act Sections 111(c)(1) or 112(l)(1). However, all applicable test methods and other requirements in the Appendices must be followed as required by the delegated subparts (see EPA's proposed rule published on January 14, 2002 (67 FR 1676) and subsequent final rule published on April 26, 2002 (67 FR 20652)).

III. EPA Action

No comments were submitted that change our assessment of the delegations as described in our proposed action. Therefore, as authorized in Sections 111(c)(1) and 112(l)(1) of the Clean Air Act, EPA is updating the CFR tables for Arizona and Nevada as proposed in the Federal Register on June 21, 2007.

IV. 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 updates the list of approved delegations in the Code of Federal Regulations and imposes no additional requirements. Accordingly, the Administrator certifies that this rule 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 rule does not impose any additional enforceable duty beyond that required by state or local 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 rule 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 levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely updates the list of already-approved delegations, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule 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 or local rule implementing a federal standard.

In reviewing state or local delegation submissions, our role is to approve state or local choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State or local government to use voluntary consensus standards (VCS), EPA has no authority to disapprove state or local submissions for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a state or local submission, to use VCS in place of a state or local submission that otherwise satisfies the provisions of the Clean Air Act. 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 rule 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 June 2, 2008. 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)) of the Clean Air Act.
