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 Federally-enforceable SIP. Each Federally-approved 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 Federally-enforceable 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 state-authorized 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 Federally-approved 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 the Part 70 operating permits program?

The CAA Amendments of 1990 require all states to develop operating permits programs that meet certain Federal criteria. In implementing this program, the states are to require certain sources of air pollution to obtain permits that contain all applicable requirements under the CAA. One purpose of the part 70 operating permits program is to improve enforcement by issuing each source a single permit that consolidates all of the applicable CAA requirements into a Federally-enforceable document. By consolidating all of the applicable requirements for a facility into one document, the source, the public, and the permitting authorities can more easily determine what CAA requirements apply and how compliance with those requirements is determined.

Sources required to obtain an operating permit under this program include “major” sources of air pollution and certain other sources specified in the CAA or in our implementing regulations. For example, all sources regulated under the acid rain program, regardless of size, must obtain permits. Examples of major sources include those that emit 100 tons per year or more of volatile organic compounds, carbon monoxide, lead, sulfur dioxide, nitrogen dioxide, or PM₁₀; those that emit 10 tons per year of any single hazardous air pollutant (HAP) (specifically listed under the CAA); or those that emit 25 tons per year or more of a combination of HAPs.

Revision to the state operating permits program are also subject to public notice, comment, and our approval.

What is the Federal approval process for an operating permits program?

In order for state regulations to be included in the Federally-enforceable Title V operating permits program, states must formally adopt regulations consistent with state and Federal requirements. This process generally includes a public notice, public hearing, public comment period, and a formal adoption by a state-authorized rulemaking body.

Once a state rule, regulation, or control strategy is adopted, the state submits it to us for inclusion into the approved operating permits program. 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 502 of the CAA, including revisions to the state program, are included in the Federally-approved operating permits program. Records of such actions are maintained in the CFR at Title 40, part 70, appendix A, entitled “Approval Status of State and Local Operating Permits Programs.”

What is being addressed in this document?

EPA is approving the State Implementation Plan (SIP) revisions submitted by the state of Iowa which include minor revisions to various rules. The state of Iowa periodically makes minor revisions that are included under its general rulemaking and are typically processed twice a year. The revisions are described as follows:

With regard to Iowa's variance provision in subrule 21.2(4)“c” of the Iowa Administrative Code (IAC), the Iowa Department of Natural Resources added language to clarify the Prevention of Significant Deterioration (PSD) requirements for which they may not grant a variance and referenced the new chapter in the Iowa Administrative Code that addresses PSD requirements. The revision clarifies that variances cannot be issued to sources seeking permit limits on their potential emissions in order to avoid major source permitting requirements. In other words, a variance cannot be issued to a source seeking a synthetic minor permit.

Revisions were made to subrules 22.201(2) and 22.300(3) which address applicability of Iowa's synthetic minor permit program. The revisions correct cross references to the state's rules for Title V permits, Acid Rain permits and permits by rule for small sources. These changes apply to the SIP and Iowa's operating permits program.

Revisions were made to Chapter 25 of the IAC, relating to emissions monitoring methods, to update references to Federal reference methods and performance standards. These changes apply to SIP monitoring requirements.

Have the requirements for approval of a SIP revision and a Part 70 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, these revisions meet the substantive SIP requirements of the CAA, including section 110 and implementing regulations. These revisions are minor clarifications, updates, and corrections which do not affect the stringency of existing requirements. These revisions are also consistent with applicable EPA requirements in Title V of the CAA and 40 CFR Part 70.

What action is EPA taking?

EPA is approving these revisions submitted by Iowa on April 26, 2007, to update the SIP and the Iowa Operating Permits Program to include minor revisions and updates. We are processing this action as a direct final action because the revisions make routine changes to the existing rules which are noncontroversial. 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 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 action 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 action 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 (Pub. L. 104-4).

This action 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 standard, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. This action 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 rule implementing a Federal standard.

In reviewing state submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. 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 state submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a state submission, to use VCS in place of a state submission that otherwise satisfies the provisions of the CAA. 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 action 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 December 17, 2007. 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).)
