ENVIRONMENTAL PROTECTION AGENCY
40 CFR Parts 52 and 81

[FRL-5560-4]


Approval and Promulgation of Implementation Plans; Designation of 
Areas for Air Quality Planning Purposes; Wyoming; Corrections

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rulemaking.

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

SUMMARY: EPA is promulgating corrections to the State Implementation 
Plan (SIP) for the State of Wyoming regarding the State's ambient 
standards for fluorides and hydrogen sulfide and the State's odor 
control regulation. EPA has determined that these rules were 
erroneously incorporated into the SIP. EPA is removing these rules from 
the approved Wyoming SIP because the rules do not have a reasonable 
connection to the national ambient air quality standards (NAAQS) and 
related air quality goals of the Clean Air Act. The intended effect of 
this correction to the SIP is to make the SIP consistent with the 
requirements of the Clean Air Act, as amended in 1990 (``the Act''), 
regarding EPA action on SIP submittals and SIPs for national primary 
and secondary ambient air quality standards.
    In addition, EPA is amending the boundary description for the 
``Powder River Basin'' PM-10 unclassifiable area in 40 CFR 81.351. EPA 
promulgated revisions to 40 CFR 81.351 in a November 3, 1995 
rulemaking, and EPA erroneously published an incorrect boundary 
description for the Powder River Basin area. This document corrects 
that error.

DATES: This action will become effective on November 5, 1996, unless 
adverse comments are received within 30 days of publication. If the 
effective date is delayed, timely notice will be published in the 
Federal Register.

ADDRESSES: Copies of the documents relative to this action are 
available for inspection during normal business hours at the following 
location: Air Program, Environmental Protection Agency, Region VIII, 
999 18th Street, Suite 500, Denver, Colorado 80202-2466.

SUPPLEMENTARY INFORMATION:

I. Corrections to SIP

    The Act was first amended in 1970. At this time, a large number of 
SIPs were submitted to EPA to fulfill the new Federal requirements. In 
many cases, states and districts submitted their entire programs, 
including many elements not required pursuant to the Act. Due to 
resource constraints at that time, EPA's review of these submittals 
focused primarily on the required technical, legal, and enforcement 
elements of the submittals. At the time, EPA did not perform a detailed 
review of the numerous provisions submitted, to determine if each 
provision was related to protection of the NAAQS. Provisions approved 
as part of states' SIPs should generally be related to attainment and 
maintenance of the NAAQS, consistent with the authority in section 110 
of the Act under which these plans are approved by EPA.
    During a recent review of the contents of the Wyoming SIP, EPA 
determined that three provisions of the State's rules were approved as 
part of the SIP which did not have a reasonable connection to the 
NAAQS-related air quality goals of the Act. These State rules include 
the ambient standard for hydrogen sulfide in Section 7 of the Wyoming 
Air Quality Standards and Regulations (WAQSR), the 1972 version of the 
ambient standard for fluorides in Section 11 of the WAQSR,1 and 
the odor control rules in Section 16 of the WAQSR. In addition, 
documents included in the State's November 19, 1993 title V operating 
permit program submittal indicated that the State did not consider 
these three rules part of the federally-approved SIP. EPA consequently 
notified the State of this discrepancy in a June 26, 1995 letter and 
offered to correct the SIP pursuant to section 110(k)(6) of the Act by 
removing these three rules from the SIP, since they are not reasonably 
connected to the NAAQS-related air quality goals of the Act. The State 
responded in a letter dated September 19, 1995 requesting that EPA 
remove these three provisions from the approved SIP.

    \1\ Section 11 of the WAQSR was amended by the State in 1986, 
but that version was never submitted to, or approved by, EPA as part 
of the SIP for Wyoming.
---------------------------------------------------------------------------

    Section 110(k)(6) of the amended Act provides: Whenever the 
Administrator determines that the Administrator's action approving, 
disapproving, or promulgating any plan or plan revision (or part 
thereof), area designation, redesignation, classification, or 
reclassification was in error, the Administrator may in the same 
manner as the approval, disapproval, or promulgation revise such 
action as appropriate without requiring any further submission from 
the State. Such determination and the basis thereof shall be 
provided to the State and public.

    Since the State of Wyoming's rules for hydrogen sulfide ambient 
standards, fluoride ambient standards, and odor control have no 
reasonable connection to the NAAQS-related air quality goals of the Act 
and since the State has requested that EPA remove these rules from the 
approved SIP, EPA has found that approval of these State rules was in 
error. Consequently, EPA is removing Sections 7, 11, and 16 of the 
WAQSR from the approved Wyoming SIP pursuant to section 110(k)(6) of 
the Act.

II. Correction of Boundary Description for the Powder River Basin 
Area

    On November 3, 1995, EPA promulgated revisions to the State of 
Wyoming's PM-10 area designation table in 40 CFR 81.351 pursuant to the 
State's adoption and EPA's approval of prevention of significant 
deterioration (PSD) increments for PM-10 (see 60 FR 55800). In that 
notice, EPA cited an earlier and incorrect boundary description for the 
area designated as the ``Powder River Basin'' in Campbell and Converse 
counties. EPA promulgated a revised boundary description for the Powder 
River Basin area on September 12, 1995 (60 FR 47299), and that revised 
boundary

[[Page 47059]]

should have been reflected in the November 3, 1995 rulemaking. 
Therefore, this notice corrects the boundary description for the Powder 
River Basin area to reflect the September 12, 1995 rulemaking.

III. Final Action

    EPA is removing Sections 7, 11, and 16 of the WAQSR from the 
approved Wyoming SIP pursuant to section 110(k)(6) of the Act. In 
addition, EPA is correcting the boundary description for the Powder 
River Basin PM-10 unclassifiable area in 40 CFR 81.351 to reflect the 
boundary description promulgated for the area on September 12, 1995 (60 
FR 47299).
    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, EPA is proposing to correct the SIP should 
adverse or critical comments be filed. Under the procedures established 
in the May 10, 1994 Federal Register (59 FR 24054), this action will be 
effective November 5, 1996, unless, by October 7, 1996, adverse or 
critical comments are received.
    If such comments are received, this action will be withdrawn before 
the effective date by publishing a subsequent document that will 
withdraw the final action. All public comments received will then be 
addressed in a subsequent final rule based on this action serving as a 
proposed rule. 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 on November 5, 1996.
    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 a SIP shall be 
considered separately in light of specific technical, economic, and 
environmental factors and in relation to relevant statutory and 
regulatory requirements.

IV. Administrative Requirements

A. Executive Order 12866

    This action has been classified as a Table 3 action for signature 
by the Regional Administrator under the procedures published in the 
Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a 
July 10, 1995 memorandum from Mary Nichols, Assistant Administrator for 
Air and Radiation. The Office of Management and Budget (OMB) has 
exempted this regulatory action from E.O. 12866 review.

B. Regulatory Flexibility Act

    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 economic 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. This action does not impose any new requirements. 
Therefore, the Administrator certifies that this action will not have a 
significant impact on a substantial number of small entities.

C. Unfunded Mandates

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
costs to State, local, or tribal governments in the aggregate; or to 
the private sector, of $100 million or more. Under section 205, EPA 
must select the most cost-effective and least burdensome alternative 
that achieves the objectives of the rule and is consistent with 
statutory requirements. Section 203 requires EPA to establish a plan 
for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule.
    EPA has determined that this correction action promulgated does not 
include a Federal mandate that may result in estimated costs of $100 
million or more to either State, local, or tribal governments in the 
aggregate, or to the private sector. This Federal action corrects this 
state implementation plan, pursuant to section 110(k)(6) of the Act, by 
removing three State rules that were erroneously incorporated into the 
SIP. Thus, this action will impose no new requirements. Accordingly, no 
additional costs to State, local, or tribal governments, or to the 
private sector, result from this action.

D. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, EPA submitted 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 
General Accounting Office prior to publication of the rule in today's 
Federal Register. This rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

E. Petitions for Judicial 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 November 5, 1996. 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 must 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)).
