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.
