Clean Air Act Approval and Promulgation of New Source Review 
Implementation Plan for Wyoming

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The EPA is fully approving revisions to the State 
Implementation Plan (SIP) submitted by the State of Wyoming for the 
purpose of meeting requirements of the Clean Air Act (Act), as amended 
in 1990, with regard to New Source Review (NSR) in areas that have not 
attained the National ambient air quality standards (NAAQS). The 
revision to the implementation plan was submitted by the State on 
November 12, 1993 to satisfy certain Federal requirements for an 
approvable non-attainment NSR SIP for Wyoming. Also in this document, 
EPA is approving other minor revisions to the State's NSR rules which 
were included in the State's November 12, 1993 submittal.
DATES: This direct final rule is effective January 30, 1995 unless 
notice is received by December 29, 1994 that someone wishes to submit 
adverse comments. If the effective date is delayed, timely notice will 
be published in the Federal Register.

ADDRESSES: Comments should be addressed to Vicki Stamper, 8ART-AP, at 
the EPA Regional Office listed.
    Copies of the State's submittal and other information are available 
for inspection during normal business hours at the following location: 
Environmental Protection Agency, Region VIII, Air Programs Branch, 999 
18th Street, suite 500, Denver, Colorado 80202-2466; and Air Quality 
Division, Department of Environmental Quality, Herschler Building, 4th 
floor, 122 West 25th Street, Cheyenne, Wyoming, 82002.

SUPPLEMENTARY INFORMATION:

I. Background

    The air quality planning requirements for non-attainment new source 
review are set out in part D of title I of the Act. The EPA has issued 
a ``General Preamble'' describing EPA's preliminary views on how EPA 
intends to review SIPs and SIP revisions submitted under part D, 
including those State submittals containing non-attainment area NSR SIP 
requirements (see 57 FR 13498 (April 16, 1992) and 57 FR 18070 (April 
28, 1992)). Because EPA is describing its interpretations here only in 
broad terms, the reader should refer to the General Preamble for a more 
detailed discussion of the interpretations of part D advanced in this 
proposal and the supporting rationale.
    EPA is currently developing a proposed rule to implement the 
changes under the 1990 Amendments in the new source review provisions 
in parts C and D of title I of the Act. The Agency anticipates that the 
proposed rule will be published for public comment in late 1994. If EPA 
has not taken final action on States' NSR submittals by that time, EPA 
will refer to the proposed rule as the most authoritative guidance 
available regarding the approvability of the submittals. EPA expects to 
take final action to promulgate a rule to implement the parts C and D 
changes sometime during 1994/1995. Upon promulgation of those 
regulations, EPA will review those NSR SIP submittals on which it has 
taken final action to determine whether additional SIP revisions are 
necessary.
    The State of Wyoming only has one non-attainment area. It is the 
City of Sheridan, which is designated as a moderate PM10 non-
attainment area. The non-attainment NSR provisions applicable to 
moderate PM10 non-attainment areas are found in sections 173 and 
189(e) of the Act. In general, section 173 allows permits to be issued 
for the construction or modification of major stationary sources 
proposing to locate in non-attainment areas only if the following 
conditions are met: (1) The new or modified major stationary source has 
obtained emission offsets from the same or other sources in the region 
which provide for reasonable further progress towards attainment of the 
NAAQS; (2) the new or modified major stationary source must comply with 
the lowest achievable emission rate; (3) the owner of the proposed new 
or modified major stationary source has demonstrated that all other 
sources in the State owned, operated, or controlled by the owner of the 
proposed source are in compliance, or on a schedule for compliance, 
with all applicable emission limitations and standards under the Act; 
(4) the EPA Administrator has not determined that the applicable SIP is 
not being adequately implemented for the non-attainment area in which 
the proposed source is to be constructed or modified; and (5) an 
alternative siting analysis has been prepared which demonstrates that 
the benefits of the proposed source significantly outweigh the 
environmental and social costs imposed as a result of the proposed 
source's location, construction, or modification.
    Section 302(j) of the Act sets the threshold for defining a major 
stationary source at 100 tons per year, and States' non-attainment NSR 
rules must reflect this major stationary source threshold, unless a 
more stringent threshold is required in subparts 2-4 of part D of the 
Act (which includes specific provisions for ozone, carbon monoxide, and 
PM10 non-attainment areas). For moderate PM10 non-attainment 
areas, there is not a more stringent major stationary source threshold 
and, thus, State non-attainment NSR rules must comply with the 100 tons 
per year threshold of the section 302(j) definition.
    The only additional requirements of subpart 4 of part D of the Act 
required for moderate PM10 non-attainment areas are those of 
section 189(e) of the Act. Section 189(e) provides that the control 
requirements applicable to new and modified major stationary sources of 
PM10 also apply to new and modified major stationary sources of 
PM10 precursors, unless the Administrator finds that such sources 
do not contribute significantly to PM10 levels which exceed the 
standards in the area. On June 23, 1994, EPA announced its final 
determination that sources of PM10 precursors do not contribute 
significantly to PM10 exceedances in the Sheridan PM10 non-
attainment area (59 FR 32361). Consequently, the requirements of 
section 189(e) do not apply to the Sheridan PM10 non-attainment 
area.
    States with moderate PM10 non-attainment areas were required 
to submit NSR rules meeting the general requirements discussed above 
and any additional requirements of subpart 4 of part D by June 30, 
1992.
    In the August 28, 1989 State submittal of the moderate PM10 
non-attainment area SIP for Sheridan, it was stated that section 21 of 
the State's regulations prohibited the construction or modification of 
major stationary sources in non-attainment areas by prohibiting the 
construction or modification of sources which would have a significant 
ambient impact on air quality in the non-attainment area. However, 
after further review of the State's regulation, EPA determined that the 
State's regulation did not provide adequate assurance that no new or 
modified major stationary source would be able to construct in a non-
attainment area. In a March 19, 1993 letter, EPA notified the State of 
this determination and provided the State with two options for meeting 
the Federal NSR permitting requirements. Either the State couldimpose a 
construction ban by adopting the Federal definitions of ``major 
stationary source'' and ``major modification'' in 40 CFR 
51.165(a)(1)(iv)and (a)(1)(v) and prohibiting the construction of 
sources meeting those definitions in the Sheridan PM10 non-
attainment area, OR the State could adopt a NSR permitting program 
meeting the requirements of 40 CFR 51.165 as well as the new 
requirements in section 173 of the Act. The State chose the first 
option.
    On September 16, 1993, the State of Wyoming adopted revisions to 
section 21 of its regulations which prohibit the construction or 
modification of major stationary sources of PM10 in the Sheridan 
PM10 non-attainment area. The State also adopted other minor 
revisions to its NSR permitting regulations in section 21. The Governor 
subsequently submitted these revisions for approval in the SIP on 
November 12, 1993.
    In this rulemaking action on the Wyoming non-attainment NSR SIP 
submittal, EPA is applying its interpretations taking into 
consideration the specific factual issues presented.

II. State Submission

    Section 110(k) of the Act sets out provisions governing EPA's 
review of SIP submittals (see 57 FR 13565-13566).

A. Procedural Background

    The Act requires States to observe certain procedural requirements 
in developing implementation plans and plan revisions for submission to 
EPA. Section 110(a)(2) of the Act provides that each implementation 
plan submitted by a State must be adopted after reasonable notice and 
public hearing. Section 110(1) of the Act similarly provides that each 
revision to an implementation plan submitted by a State under the Act 
must be adopted by such State after reasonable notice and public 
hearing.
    The EPA also must determine whether a submittal is complete and 
therefore warrants further EPA review and action (see section 110(k)(1) 
and 57 FR 13565, April 16, 1992). The EPA's completeness criteria for 
SIP submittals are set out at 40 CFR part 51, appendix V. The EPA 
attempts to make completeness determinations within 60 days of 
receiving a submission. However, a submittal is deemed complete by 
operation of law under section 110(k)(1)(B) if a completeness 
determination is not made by EPA within 6 months after receipt of the 
submission.
    The State of Wyoming held a public hearing on July 22, 1993 to 
entertain public comment on the new source review implementation plan. 
Following the public hearing, the plan was adopted by the Environmental 
Quality Council on September 16, 1993, became effective on October 26, 
1993, and was submitted to EPA on November 12, 1993 as a revision to 
the SIP.
    The SIP revision was reviewed by EPA to determine completeness 
shortly after its submittal, in accordance with the completeness 
criteria referenced above. The submittal was found to be complete, and 
a letter dated January 7, 1994 was forwarded to the Governor indicating 
the completeness of the submittal and the next steps to be taken in the 
review process. In this action, EPA approves the State of Wyoming's 
non-attainment new source review SIP submittal.

B. Evaluation of State Submittal

    On November 12, 1993, the Governor of Wyoming submitted for EPA 
approval revisions to the SIP for Air Quality consisting of revisions 
to section 21 of the Wyoming Air Quality Standards and Regulations 
(WAQSR), Permit requirements for construction, modification and 
operation. The revisions were designed to accomplish the following 
purposes: (a) Revise the existing permit requirements for operating 
permits to properly interface with the new section 30, Operating 
Permits regulation; (b) provide for collection of fees to cover the 
cost of reviewing and issuing permits under section 21; and (c) provide 
for a prohibition of construction or modification of major sources of 
PM10 in the City of Sheridan PM10 non-attainment area until 
such time as the area is designated attainment for PM10. These are 
discussed more fully in the following paragraphs:

    (a) Section 21(c)(ii)(B) prohibits the construction or modification 
of major stationary sources of PM10 within the City of Sheridan 
PM10 non-attainment area until such time as the area is 
redesignated to attainment. This was submitted to satisfy the NSR 
requirements for the State's PM10 non attainment area, which were 
required to be submitted by June 30, 1992.
    (b) In order to make the regulations consistent with the section 30 
Operating Permit regulations and to integrate section 30 into existing 
air quality programs, the State revised sections 21(a)(ii),(iii), and 
(v), and 21(o). These sections clarify the difference between section 
21 permit requirements, and the title V permit requirements in section 
30, and imposes fees for section 21 permitting actions. EPA has 
reviewed the provisions in section 21(c)(ii)(B) and believes that the 
State regulation will effectively prohibit the construction or 
modification of major stationary sources of PM10 in the Sheridan 
PM10 nonattainment area. Because the State has elected to adopt a 
construction ban rather than adopting nonattainment NSR permitting 
regulations for new or modified major sources in the Sheridan PM10 
nonattainment, EPA believes the State has adequately met the 
nonattainment NSR requirements of part D of the Act by adopting more 
stringent provisions. In addition, EPA has reviewed the other revisions 
to section 21 and believes they provide for consistency with the 
corresponding Federal regulations in 40 CFR part 51 and clarity within 
the State's regulations. EPA is therefore approving the revisions to 
Wyoming's NSR regulations.

III. Implications of This Action

    The EPA is approving the revisions to the Wyoming SIP submitted by 
the State of Wyoming on November 12, 1993, which include revisions to 
section 21 of the WAQSR pertaining to construction permit requirements. 
The State of Wyoming has submitted a complete plan which meets the NSR 
requirements of part D of the Act. EPA is also approving other minor 
revisions to section 21, which were included in the November 12, 1993 
submittal.
    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. Under the procedures 
established in the May 10, 1994 Federal Register (59 FR 24054), this 
action will be effective January 30, 1995 unless, by December 29, 1994, 
adverse or critical comments are received.
    If the EPA receives such comments, 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. 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 January 30, 1995.
    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any State Implementation Plan. Each request for revision to 
any State Implementation Plan shall be considered separately in light 
of specific technical, economic, and environmental factors and in 
relation to relevant statutory and regulatory requirements.
    The OMB has exempted these actions from review under Executive 
Order 12866.
    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
must prepare a regulatory flexibility analysis addressing 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 population of less than 
50,000.
    SIP approvals under section 110 and subchapter I, part D of the 
Clean Air Act 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 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 
Clean Air Act forbids EPA to base its action concerning SIP's 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).
    Under section 307(b)(1) of the Act, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by January 30, 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)).
