SUPPLEMENTARY INFORMATION:

I. Background

On October 13, 2005 (70 FR 59688), EPA published a notice of proposed rulemaking (NPR) for the State of Maryland. The NPR proposed approval of modifications to the ambient air quality standards for ozone and fine particulate matter (PM2.5) and the replacement of the abbreviation “ppm” with parts per million in existing standards. The official SIP revision (#05-01) was submitted by the State of Maryland on March 15, 2005.

II. Summary of SIP Revision

Maryland's revision incorporates the 1997 Federal 8-hour ozone and PM2.5 standards into Title 26, Subtitle 11, Chapter 4 of the Code of Maryland Administrative Regulations (COMAR 26.11.04). The new ozone standard incorporated in this SIP revision is the average of the fourth-highest daily maximum 8-hour average ozone concentration that is less than or equal to 0.08 ppm, averaged over three consecutive years. The standards for PM2.5 incorporated in this SIP revision are 65 micrograms per cubic meter based on a 24-hour concentration and 15.0 micrograms per cubic meter annual arithmetic mean concentration. The revision also includes a clarification of the unit of measure for ambient air quality standards for sulfur oxides and nitrogen dioxide. The abbreviation “ppm” has been replaced by the written form “parts per million”. No public comments were received on the NPR.

III. Final Action

EPA is approving the amendments to COMAR 26.11.04, consisting of the addition of new 8-hour ozone ambient air quality standards and fine particulate matter ambient air quality standards, as well as clarification of the Start Printed Page 34258unit of measure, as a revision to the Maryland SIP.

IV. Statutory and Executive Order Reviews

A. General Requirements

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 approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. 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 approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state 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 (Public Law 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 approves a state rule implementing a Federal requirement, 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 is not economically significant.

In reviewing SIP submissions, EPA's role is to approve state 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 to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP 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.).

B. Submission to Congress and the Comptroller General

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. This rule is not a “major rule” as defined by 5 U.S.C. 804(2).

C. Petitions for Judicial Review

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 August 14, 2006. 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 to approve modifications to the ambient air quality standards for ozone and fine particulate matter may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
