AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule; notice of administrative change.

SUMMARY:

EPA is updating the materials submitted by Iowa that are incorporated by reference (IBR) into the State implementation plan (SIP). The regulations affected by this update have been previously submitted by the State agency and approved by EPA. This update affects the SIP materials that are available for public inspection at the National Archives and Records Administration (NARA), the Air and Radiation Docket and Information Center located at EPA Headquarters in Washington, DC, and the Regional Office.

DATES:

Effective Date: This action is effective July 29, 2009.

ADDRESSES:

SIP materials which are incorporated by reference into 40 CFR part 52 are available for inspection at the following locations: Environmental Protection Agency, Region 7, 901 North 5th Street, Kansas City, Kansas 66101; or at http://www.epa.gov/​region07/​programs/​artd/​air/​rules/​fedapprv.htm; the Air and Radiation Docket and Information Center, EPA Headquarters Library, Room Number 3334, EPA West Building, 1301 Constitution Avenue, NW., Washington, DC 20460, and the National Archives and Records Administration. If you wish to obtain materials from a docket in the EPA Headquarters Library, please call the Office of Air and Radiation Docket at (202) 566-1742.

SUPPLEMENTARY INFORMATION:

The SIP is a living document which the State revises as necessary to address the unique air pollution problems in the State. Therefore, EPA from time to time must take action on SIP revisions containing new and/or revised regulations to make them part of the SIP. On May 22, 1997 (62 FR 27968), EPA revised the procedures for incorporating by reference Federally approved SIPs, as a result of consultations between EPA and the Office of the Federal Register. The description of the revised SIP document, IBR procedures and “Identification of plan” format are discussed in further detail in the May 22, 1997, Federal Register document.

On February 12, 1999, EPA published a document in the Federal Register (64 FR 7091) beginning the new IBR procedure for Iowa. On September 23, 2004 (69 FR 56942), EPA published an update to the IBR material for Iowa.

In this document, EPA is doing the following:

1. Announcing the update to the IBR material as of July 1, 2009.

2. Correcting the date format in the “State effective date” or “State Submittal date” and “EPA approval date” columns in § 52.820 paragraphs (c), (d) and (e). Dates are numerical month/day/year without additional zeros.

3. Modifying the Federal Register citation in § 52.820 paragraphs (c), (d) and (e) to reflect the beginning page of the preamble as opposed to the page number of the regulatory text.

4. Removing the second entry for 567-22.4 in § 52.820 paragraph (c) under Chapter 22.

EPA has determined that today's rule falls under the “good cause” exemption in section 553(b)(3)(B) of the Administrative Procedures Act (APA) which, upon finding “good cause,” authorizes agencies to dispense with public participation and section 553(d)(3), which allows an agency to make a rule effective immediately (thereby avoiding the 30-day delayed effective date otherwise provided for in the APA). Today's rule simply codifies provisions which are already in effect as a matter of law in Federal and approved State programs. Under section 553 of the APA, an agency may find good cause where procedures are “impractical, unnecessary, or contrary to the public interest.” Public comment is “unnecessary” and “contrary to the public interest” since the codification only reflects existing law. Immediate notice in the CFR benefits the public by providing notice of the updated Iowa SIP compilation.

Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Start Printed Page 37557Federal 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 Clean Air Act. 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 Order 12866 (58 FR 51735, October 4, 1993);
  • 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 Clean Air Act; 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 rule 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.

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 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).

EPA has also determined that the provisions of section 307(b)(1) of the Clean Air Act pertaining to petitions for judicial review are not applicable to this action. This action is simply an announcement of prior rulemakings that have previously undergone notice and comment. Prior EPA rulemaking actions for each individual component of the Iowa SIP compilation previously afforded interested parties the opportunity to file a petition for judicial review in the United States Court of Appeals for the appropriate circuit within 60 days of such rulemaking action.
