40 CFR Part 52

[IA-12-1-6529a; FRL-5110-3]

 

Approval and Promulgation of Implementation Plans; State of Iowa

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: This final action approves the State Implementation Plan (SIP) 
submitted by the state of Iowa. The revision includes updating several 
incorporations by reference and conformity to Federal regulations which 
strengthen maintenance of established air quality standards.

DATES: This action will be effective February 21, 1995 unless adverse 
or critical comments are received.

ADDRESSES: Copies of the documents relevant to this action are 
available for public inspection during normal business hours at the 
Environmental Protection Agency, Air Branch, 726 Minnesota Avenue, 
Kansas City, Kansas 66101; and EPA Air & Radiation Docket and 
Information Center, 401 M Street SW., Washington, DC 20460.

FOR FURTHER INFORMATION CONTACT: Christopher D. Hess at (913) 551-7213.

SUPPLEMENTARY INFORMATION: Beginning with its initial submission in 
1972, the state of Iowa has operated a federally approved SIP that has 
implemented the various requirements of the Clean Air Act (Act) and the 
Code of Federal Regulations (CFR). During the past two decades, 
numerous revisions and updates have been made to the SIP in response to 
new Federal requirements.
    On May 5, 1994, the state of Iowa requested an SIP revision under 
the authority and signature of the Governor's designee, Larry J. 
Wilson, Director, Iowa Department of Natural Resources (IDNR). This 
submission has been deemed complete in accordance with the criteria 
specified in 40 CFR part 51, appendix V. The state has provided 
evidence of the lawful adoption of regulations, public notice, and 
public hearing requirements.

Rule Revisions for the SIP

    The state has adopted a total of five revisions in two actions by 
the Environmental Protection Commission (EPC). In the first action, 
effective January 12, 1994, the state amends its rules in paragraph 
23.2(3)g with respect to training fires. In the state's previous rule, 
fires set for training fire-fighting employees required notification of 
the director at least one week prior to the event. The state has 
determined that it desires to make this requirement for notification 
consistent with the requirements in 40 CFR 61.145, as amended through 
March 5, 1992. The Federal requirement specifies 10 days' notification 
which the state now adopts.
    In the second action, effective April 20, 1994, the state amended 
four rules now submitted as revisions to the SIP.
    1. In Iowa rule 567-22.4, the state previously adopted by reference 
40 CFR 52.21, as amended through February 3, 1992, with respect to 
special requirements for major stationary sources located in areas 
designated attainment or unclassified (PSD). The state now updates this 
adoption to include the modeling guidelines and PM10 increments 
specified in the June 3, 1993, Federal Register document and changes in 
Sec. 52.21 which became effective June 3, 1994.
    2. In Iowa rule 23.3(2)d (3) and (4), the state previously allowed 
use of the Ringelmann Chart or an opacity determination in regulating 
diesel-powered vehicles and locomotives. Since the state has adopted 
Test Method 9 for opacity as found in 40 CFR part 60, appendix A (also 
in this April 20, 1994, adoption), the state hereby ceases to use the 
Ringelmann Chart.
    3. In subrule 23.4(6), the state amends a typographical error in a 
rule concerning emissions of particulate matter in sand handling and 
surface finishing operations in metal processing. The rule itself is 
unchanged.
    4. In subrule 25.1(9), the state previously outlined its test 
methods and procedures by adopting those specified in 40 CFR part 60, 
appendices B and F through February 11, 1991. The state now updates its 
adoption to include appendix A of part 60 and include amendments 
through May 17, 1993. This adoption includes Test Method 9 for opacity 
as outlined in 2. above.

EPA Action

    EPA is taking final action to approve revisions submitted May 15, 
1994, for the state of Iowa.
    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any SIP. Each request for revision to the SIP shall be 
considered separately in light of specific technical, economic, and 
environmental factors and in relation to relevant statutory and 
regulatory requirements.
    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed or final rule on small entities (5 U.S.C. 603 and 604). 
Alternatively, EPA may certify that the rule will not have a 
significant impact on a substantial number of small entities. Small 
entities include small businesses, small not-for-profit enterprises, 
and government entities with jurisdiction over populations of less than 
50,000.
    SIP approvals under section 110 and subchapter I, part D of the CAA 
do not create any new requirements, but simply approve requirements 
that the state is already imposing. Therefore, because the Federal SIP 
approval does not impose any new requirements, EPA certifies that it 
does not have a significant impact on any small entities affected. 
Moreover, due to the nature of the Federal-state relationship under the 
CAA, preparation of a regulatory flexibility analysis would constitute 
Federal inquiry into the economic reasonableness of state action. The 
CAA forbids EPA to base its actions concerning SIPs on such grounds 
(Union Electric Co. v. U.S. E.P.A., 427 U.S. 246, 256-66 (S.Ct. 1976); 
42 U.S.C. 7410(a)(2)).
    The Office of Management and Budget has exempted these actions from 
review under Executive Order 12866.
    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 February 21, 1995. 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).)
    The EPA is publishing this action without prior proposal because 
the Agency views this as a noncontroversial amendment and anticipates 
no adverse comments. However, in a separate document in the Federal 
Register publication, the EPA is proposing to approve the SIP revision 
should adverse or critical comments be filed.
    If the EPA receives such comments, this action will be withdrawn 
before the effective date by publishing a subsequent notice that will 
withdraw the final action. All public comments received will then be 
addressed in a subsequent rule based on this action serving as a 
proposed rule. The EPA will not institute a second comment period on 
this action. Any parties interested in commenting on this action should 
do so at this time.
