Approval and Promulgation of Implementation Plans: State of Idaho

AGENCY: Environmental Protection Agency.

ACTION: Direct final rule.

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

SUMMARY: On August 25, 1994, the Environmental Protection Agency (EPA) 
issued a direct final rule approving the State Implementation Plan for 
the Pinehurst, Idaho, PM-10 (particulate matter with an aerodynamic 
diameter of less than or equal to a nominal ten micrometers) 
nonattainment area (59 FR 43745 (August 25, 1994)). In this rulemaking 
action, EPA is approving the provisions of that plan for the area just 
outside the City of Pinehurst which was designated nonattainment in 
January 1994.

SUPPLEMENTARY INFORMATION:

I. Background

    On August 25, 1994, EPA issued a direct final rule approving the 
State Implementation Plan (SIP) for the Pinehurst PM-10 nonattainment 
area in Shoshone County, Idaho. See 59 FR 43745. The rule became 
effective October 24, 1994. In that document, EPA described its 
approval action as covering the Pinehurst, Idaho nonattainment area 
that was designated nonattainment for PM-10 and classified as moderate 
under sections 107(d)(4)(B) and 188(a) of the Clean Air Act upon 
enactment of the 1990 Clean Air Act Amendments (citing 56 FR 56694 
(November 6, 1991)).\1\ The document inadvertently failed to explain, 
however, that, effective January 20, 1994, EPA approved the 
redesignation of an additional area in Shoshone County, adjacent to the 
Pinehurst nonattainment area, as nonattainment for PM-10. See 58 FR 
67334, 67339 (December 21, 1993) and 40 CFR 81.313 (codified air 
quality designations for the State of Idaho). Further, the August 25, 
1994 document did not explain that the SIP revision submitted by Idaho 
to address certain moderate PM-10 nonattainment planning requirements 
for Pinehurst also applied to the adjacent moderate PM-10 nonattainment 
area.

    \1\The 1990 Amendments to the Clean Air Act made significant 
changes to the Act. See Public Law No. 101-549, 104 Stat. 2399. 
References herein are to the Clean Air Act, as amended (``Act'' or 
``CAA''). The Clean Air Act is codified, as amended, in the U.S. 
Code at 42 U.S.C. 7401, et seq.
II. This Action

    In this action, EPA is approving the PM-10 SIP submitted by the 
State of Idaho on April 14, 1992 and described in the August 25, 1994 
Federal Register [[Page 27892]] document (59 FR 43745), as meeting 
certain Clean Air Act moderate PM-10 nonattainment area planning 
requirements for the portion of the Shoshone County, Idaho 
nonattainment area outside the City of Pinehurst.
    In the Federal Register document approving the redesignation of the 
area just outside the City of Pinehurst (hereinafter, the ``Pinehurst 
expansion area''), EPA noted that if the moderate area PM-10 SIP 
developed by the State for the City of Pinehurst also addressed the 
Pinehurst expansion area and was ultimately approved by EPA, it would 
satisfy the applicable planning requirements and therefore be 
unnecessary for the State to submit a separate moderate area plan 
addressing the Pinehurst expansion area. See 58 FR 67339. The control 
strategies, attainment demonstration and other plan elements of the SIP 
submitted by the State for the City of Pinehurst did in fact cover the 
nonattainment boundary as revised effective January 20, 1994, although 
EPA inadvertently failed to discuss this in its August 25, 1994 
approval action. There are no differences in the manner in which the 
control strategies and other plan elements apply within the City of 
Pinehurst, on the one hand, and within the Pinehurst expansion area, on 
the other hand. The plan cites the resolution of the Pinehurst City 
Council supporting the voluntary wood burning curtailment program as a 
factor in the program's effectiveness. However, there is no reason to 
expect that the program would have less effect in the Pinehurst 
expansion area, which is just outside city limits. Additionally, the 
woodstove replacement and weatherizations programs are being applied to 
the Pinehurst expansion area. Therefore, the evaluation and conclusions 
in EPA's August 25, 1994 action approving the SIP for the City of 
Pinehurst apply equally to the Pinehurst expansion area. Thus, EPA is 
approving the Idaho SIP revision addressed in the August 25, 1994, 
Federal Register document as also satisfying certain moderate PM-10 
nonattainment planning requirements for the additional PM-10 
nonattainment area in Shoshone County referred to as the Pinehurst 
expansion area. See 40 CFR 81.313. EPA concludes that the State has 
satisfied the requirements calling for: reasonably available control 
measures (including reasonably available control technology); a 
demonstration that the area will attain the PM-10 national ambient air 
quality standards (NAAQS) as expeditiously as practicable; an accurate 
emissions inventory; and the other moderate PM-10 nonattainment 
planning requirements discussed in the August 25, 1994 Federal Register 
document and underlying documents. EPA is also determining that major 
stationary sources of PM-10 precursors do not contribute significantly 
to PM-10 levels in excess of the NAAQS in the Pinehurst expansion area 
and is therefore granting the exclusion from precursor control 
requirements set out at section 189(e) of the CAA. See generally CAA 
section 172 (c), 188 & 189; 57 FR 13498 (April 16, 1992) & 57 FR 18070 
(April 28, 1992).
    However, as indicated in the August 25, 1994 Federal Register 
document, the State has not satisfied the requirement for contingency 
measures for either the City of Pinehurst or the Pinehurst expansion 
area. See CAA section 172 (c)(9) and 59 FR at 43750-43751. Contingency 
measures for the City of Pinehurst were due on November 15, 1993 and 
the State has until July 13, 1995 to correct this deficiency for the 
City of Pinehurst or it will face federal highway or offset sanctions. 
See 57 FR 13543 & 59 FR 43751. Contingency measures for the Pinehurst 
expansion area are due July 20, 1995. See 58 FR 67341. The State's 
obligation to submit a permit program for the construction and 
operation of new and modified stationary sources of PM-10 (NSR program) 
in the Pinehurst expansion area by July 13, 1995, has been satisfied by 
the State's May 17, 1994 submittal of an NSR program covering all 
nonattainment areas in the State. EPA is currently in the process of 
reviewing the State's NSR program to determine if the program meets the 
requirements of the CAA. EPA intends to take action on Idaho's NSR 
program when EPA has completed its review.
    For additional discussion of the control measures and other 
planning requirements contained in the SIP and EPA's analysis, please 
see the State submittal, EPA's approval of the plan for the City of 
Pinehurst (59 FR 43745) and the docket supporting that approval.
III. Administrative Review

    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, I certify 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 Act, 
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 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 this Federal 
Register publication, the EPA is proposing to approve the SIP revision 
should adverse or critical comments be filed. This action will be 
effective July 25, 1995 unless, within 30 days of its publication, 
adverse or critical comments are received.
    If 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 be addressed in a 
subsequent final 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. If no such comments are received, the public is advised that this 
action will be effective July 25, 1995.
    The EPA has reviewed this request for revision of the federally-
approved SIP for conformance with the provisions of the 1990 Clean Air 
Act Amendments enacted on November 15, 1990. The EPA has determined 
that this action conforms with those requirements.
    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.
    This action has been classified as a Table 2 action by the Regional 
Administrator under the procedures published in the Federal Register on 
January 19, 1989 (54 FR 2214-2225), as [[Page 27893]] revised by an 
October 4, 1993 memorandum from Michael H. Shapiro, Acting Assistant 
Administrator for Air and Radiation. The OMB has exempted this 
regulatory action from E.O. 12866 review.
    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 July 25, 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), 42 U.S.C. 
7607(b)(2)).
