ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[WY-001-0002b and WY-001-0003b; FRL-6344-3]


Approval and Promulgation of State Implementation Plans; Wyoming

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve two revisions to the Wyoming State 
Implementation Plan (SIP) regarding particulate matter. The SIP 
revisions include clarification and revisions to the particulate matter 
control requirements in section 25 of the Wyoming Air Quality Standards 
and Regulations (WAQSR) for the FMC Corporation in the Trona Industrial 
Area of Wyoming, and the addition of guidelines for best available 
control technology (BACT) in the minor source construction permitting 
requirements of section 21 of the WAQSR for large mining operations.
    We are also revising 40 CFR 52.2620 to list subsections 21(a)(iv), 
24(a)(xix), 24(b)(iv), and 24(b)(xii)(H) of the WAQSR in the 
``Incorporation by reference'' section. We approved these subsections 
in previous SIP approvals (on November 29, 1994 and on November 3, 
1995, respectively) but we inadvertently neglected to identify those 
subsections as incorporated into the SIP in the CFR.
    In the Rules and Regulations section of this Federal Register, we 
approve the State's submittals as a direct final rule without prior 
proposal because we view this as a noncontroversial action and 
anticipate no adverse comments. A detailed rationale for the approval 
is set forth in the preamble of the direct final rule. If no adverse 
comments are submitted, we will not take further action on this 
proposed rule. If we receive adverse comments, we will publish a timely 
withdrawal of the direct final rule in the Federal Register and it will 
not take effect. We will address all public comments in a subsequent 
final rule based on this proposed rule. We will not institute a second 
comment period on this action. Any parties interested in commenting 
must do so at this time.

DATES: Comments must be received in writing on or before June 18, 1999.

ADDRESSES: You should mail your written comments to Richard R. Long, 
Director, Air and Radiation Program, Mailcode 8P-AR, Environmental 
Protection Agency (EPA), Region VIII, 999 18th Street, Suite 500, 
Denver, Colorado, 80202. Copies of the documents relative to this 
action are available for inspection during normal business hours at the 
Air and Radiation Program, Environmental Protection Agency, Region 
VIII, 999 18th Street, Suite 500, Denver, Colorado 80202-2466. Copies 
of the State documents relevant to this action are available for public 
inspection at the Department of Environmental Quality, 122 West 25th 
Street, Cheyenne, Wyoming 82002.

FOR FURTHER INFORMATION CONTACT: Vicki Stamper, EPA Region VIII, (303)

SUPPLEMENTARY INFORMATION: See the information provided in the Direct 
Final action of the same title which is located in the Rules and 
Regulations section of this Federal Register.

    Authority: 42 U.S.C. 7401 et seq.

    Dated: May 7, 1999.
Jack W. McGraw,
Acting Regional Administrator, Region VIII.
