AGENCY:

Environmental Protection Agency (EPA).

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 Office of the Federal Register (OFR), Office of Air and Radiation Docket and Information Center, and the Regional Office.

SUPPLEMENTARY INFORMATION:

The SIP is a living document which the State can revise 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 as being 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 Federal Register (OFR). 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. In today's document EPA is updating the IBR material.

EPA is also making a minor correction to the table in § 52.820(c). On February 2, 1998 (63 FR 5269), EPA updated regulations for Linn County Health Department. The table is being updated to include information in the “Explanation” column that was inadvertently omitted. EPA is also making a minor correction to the table in § 52.820(d). On March 11, 1999 (64 FR 12090), EPA approved an administrative consent order for IES Utilities. The title of the order, which was identified as “98-AQ-20”, is corrected to read “97-AQ-20.”

On November 22, 1999 (64 FR 63694), paragraph (b) of § 52.824 Original identification of plan section was updated instead of paragraph (b) of § 52.820 Identification of plan section. We are correcting paragraph (b) of § 52.824.

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 updating citations.

Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and is therefore not subject to review by the Office of Management and Budget. This action is not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866. Because the agency has made a good cause finding that this action is not subject to notice-and-comment requirements under the Administrative Procedure Act or any other statute as indicated in the SUPPLEMENTARY INFORMATION section above, it is not subject to the regulatory flexibility provisions of the Regulatory Flexibility Act (5 U.S.C 601 et seq.), or to sections 202 and 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4). In addition, this action does not significantly or uniquely affect small governments or impose a significant intergovernmental mandate, as described in sections 203 and 204 of UMRA.

This action also does 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), nor will it 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 also is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997), because it is not economically significant. This action does not involve technical standards; 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. The action also does not involve special consideration of environmental justice related issues as required by Executive Order 12898 (59 FR 7629, February 16, 1994). With this action, EPA has taken the necessary steps to eliminate drafting errors and ambiguity, minimize potential litigation, and provide a clear legal standard for affected conduct, as required by section 3 of Executive Order 12988 (61 FR 4729, February 7, 1996). EPA has complied with Executive Order 12630 (53 FR 8859, March 15, 1998) by examining the takings implications of this action in accordance with the “Attorney General's Supplemental Guidelines for the Evaluation of Risk and Avoidance of Unanticipated Takings” issued under the executive order. This action does not impose an information collection burden under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). EPA's compliance with these statutes and Executive Orders for the underlying rules are discussed in previous actions taken on the State's rules.

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. Section 808 allows the issuing agency to make a rule effective sooner than otherwise provided by the Congressional Review Act if the agency makes a good cause finding that notice and public procedure is impracticable, unnecessary or contrary to the public interest. Today's action simply codifies provisions which are already in effect as a matter of law in Federal and approved state programs (5 U.S.C. 808(2). As previously stated, EPA has made such a good cause finding, including the reasons therefore, and established an effective date of September 23, 2004. 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 Start Printed Page 56944States prior to publication of the rule 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 CAA pertaining to petitions for judicial review are not applicable to this action. Prior EPA rulemaking actions for each individual component of the Iowa SIP compilation had 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. Thus, EPA does not believe that this action reopens the 60-day period for filing such petitions for judicial review for these “Identification of plan” actions for Iowa.
