          - [EPA-R05-OAR-2006-0004; FRL-8700-4]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

The EPA is proposing to correct its June 12, 2006, approval of a revision to the Indiana State Implementation Plan (SIP) for ozone in which it approved Indiana's exclusion of ethylene glycol monobutyl ether (EGBE), a hazardous air pollutant (HAP), as a revision to the SIP. As discussed further below, this proposed action is based upon the fact that HAPs are regulated under Section 112 of the Clean Air Act (Act). State programs related to HAPs are governed by Section 112(l) of the Act and should not be included in the SIP under Section 110, which addresses national ambient air quality standards (NAAQS) for criteria pollutants. Therefore, pursuant to section 110(k)(6) of the Act, which allows EPA to correct SIP actions made in error, EPA is proposing to rescind its exclusion of EGBE from Indiana's ozone SIP. It should be noted that EPA delisted EGBE as a HAP on November 29, 2004.

## I. What should I consider as I prepare my comments for EPA?

When submitting comments, remember to:

                    1. Identify the rulemaking by docket number and other identifying information (subject heading,                     **Federal Register**                     date and page number).                

                    2. Follow directions—The EPA may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number.                          ( print page 45186)    

3. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

4. Describe any assumptions and provide any technical information and/or data that you used.

5. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

6. Provide specific examples to illustrate your concerns, and suggest alternatives.

7. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

8. Make sure to submit your comments by the comment period deadline identified.

## II. What action is EPA taking today and what is the basis for this action?

Section 110 of the Act is the authority under which Congress has directed EPA to act on SIPs and SIP revisions. Section 110(a) establishes the applicable procedures for SIP development and submission. The trigger for these activities is the promulgation of NAAQS; and the focus of the State's efforts is to develop “a plan which provides for implementation, maintenance, and enforcement” of the NAAQS. Section 110(a)(1). EPA must then determine whether the submission contains the air quality-related components prescribed in section 110(a)(2).

Other than for lead, which is both a HAP and criteria pollutant, Section 110 does not provide parameters to determine the approvability of a HAP provision. Instead, in the 1990 Amendments to the Act, Congress envisioned that HAPs (including the then-listed EGBE) would be regulated under section 112. State programs for hazardous pollutants, including delegations, are governed by section 112(l) of the Act. They should not be included in the SIP under section 110. EPA is, therefore, proposing to correct its June 12, 2006, approval of Indiana's requested revision to delete EGBE from the definition of “hazardous air pollutant” in 326 IAC 1-2-33.5.

Section 110(k)(6) of the Act provides that whenever EPA determines that its action approving, disapproving, or promulgating any plan or plan revision (or part thereof), * * * was in error, EPA may revise such action as appropriate without requiring any further submission from the State. Therefore, under section 110(k)(6), EPA is rescinding its exclusion of EGBE from Indiana's definition of HAP, as well as Indiana's definition of HAP in 326 IAC 1-2-33.5, from Indiana's ozone SIP.

## III. Statutory and Executive Order Reviews

                    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed 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 proposed 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 proposes to correct an error and to approve state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this proposed 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 proposes to correct an error and approve preexisting 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 proposed 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 proposed 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 proposes to correct an error and approve a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This proposed 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 proposed 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.*).
