ACTION: Approval and Promulgation of Implementation Plans:

DOCUMENT ACTION: Direct final rule.

SUBJECT CATEGORY: Approval and Promulgation of Implementation Plans; State of Iowa

DATES: This direct final rule will be effective June 16, 2008, without further notice, unless EPA receives adverse comment by May 15, 2008.

DOCUMENT SUMMARY: EPA is approving a revision to the Iowa State Implementation Plan submitted on January 16, 2008. The revision includes changes to the definition of ``permitting authority'' in each of Iowa's rules used for compliance with EPA's Clean Air Interstate Rule. Iowa's SIP revision is in response to EPA's request of Iowa to revise the definitions to ensure that all allowances issued in the EPA Budget Trading Programs can be traded and used for compliance with the allowanceholding requirement in any State in the program.

SUMMARY: Iowa,

SUPPLEMENTAL INFORMATION

Throughout this document whenever ``we,'' ``us,'' or ``our'' is used, we mean EPA. This section provides additional information by addressing the following questions: What is a SIP?
What is the Federal approval process for a SIP?
What does Federal approval of a state regulation mean to me? What is being addressed in this document?

Have the requirements for approval of a SIP revision been met? What action is EPA taking?

What is a SIP?

Section 110 of the Clean Air Act (CAA) requires states to develop air pollution regulations and control strategies to ensure that state air quality meets the national ambient air quality standards established by EPA. These ambient standards are established under section 109 of the CAA, and they currently address six criteria pollutants. These pollutants are: Carbon monoxide, nitrogen dioxide, ozone, lead, particulate matter, and sulfur dioxide.

Each state must submit these regulations and control strategies to us for approval and incorporation into the Federallyenforceable SIP.

Each Federallyapproved SIP protects air quality primarily by addressing air pollution at its point of origin. These SIPs can be extensive, containing state regulations or other enforceable documents and supporting information such as emission inventories, monitoring networks, and modeling demonstrations.

What is the Federal approval process for a SIP?

In order for state regulations to be incorporated into the Federallyenforceable SIP, states must formally adopt the regulations and control strategies consistent with state and Federal requirements. This process generally includes a public notice, public hearing, public comment period, and a formal adoption by a stateauthorized rulemaking body.

Once a state rule, regulation, or control strategy is adopted, the state submits it to us for inclusion into the SIP. We must provide public notice and seek additional public comment regarding the proposed Federal action on the state submission. If adverse comments are received, they must be addressed prior to any final Federal action by us.

All state regulations and supporting information approved by EPA under section 110 of the CAA are incorporated into the Federally approved SIP. Records of such SIP actions are maintained in the Code of Federal Regulations (CFR) at title 40, part 52, entitled ``Approval and Promulgation of Implementation Plans.'' The actual state regulations which are approved are not reproduced in their entirety in the CFR outright but are ``incorporated by reference,'' which means that we have approved a given state regulation with a specific effective date. What does Federal approval of a state regulation mean to me?

Enforcement of the state regulation before and after it is incorporated into the Federallyapproved SIP is primarily a state responsibility. However, after the regulation is Federally approved, we are authorized to take enforcement action against violators. Citizens are also offered legal recourse to address violations as described in section 304 of the CAA.

What is being addressed in this document?

The SIP revision addresses changes to the definition of ``permitting authority'' in each of Iowa's rules for compliance with the Clean Air Interstate Rule (CAIR), that include the following: 567 34.201 for the annual NOX trading program, 56734.210 for the annual SO2 trading program, and 56734.221 for the ozone season trading program. Each rule has been revised to specify that the definition of ``permitting authority'' shall mean the definition contained in the corresponding EPA CAIR model rule for purposes of its use in the definitions of ``allocate or allocation'' and in all other references it shall mean the Iowa Department of Natural Resources (IDNR). Iowa has made these revisions to its State rules in response to an EPA letter request sent to the IDNR on February 17, 2007. This SIP revision is necessary to ensure that all allowances issued in the EPA Budget Trading Programs are fungible and can be traded and used for compliance with the allowanceholding requirement in any State in the program. By revising the definition of ``permitting authority'' to be consistent with the EPA CAIR model rules when used in the definitions of ``allocate or allocation,'' the IDNR ensures that allowances issued by permitting authorities other than the IDNR, such as States other than Iowa, can be used for compliance with Iowa's CAIR rules. EPA has reviewed Iowa's revised definitions and has found that Iowa has successfully incorporated EPA's recommended changes.
Have the requirements for approval of a SIP revision been met?

The state submittal has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The submittal also satisfied the completeness criteria of 40 CFR part 51, appendix V. In addition, as explained above and in more detail in the technical support document which is part of this docket, the revision meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations.

What action is EPA taking?

EPA is taking direct final action to approve a revision to the Iowa SIP submitted on January 16, 2008. We are processing this action as a direct final action because the revisions make changes to the existing rules which are noncontroversial. Therefore, we do not anticipate any adverse comments. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment.

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 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 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. 1044);

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
[[Page 20179]]
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 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).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by June 16, 2008. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action 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).)
