II. Background

    The 1990 amendments to the CAA established a comprehensive air 
quality permit program under the authority of Title V of the CAA. Title 
V requires certain facilities that emit large amounts of air pollution, 
or that meet other specified criteria, to obtain an operating permit, 
known as a Title V permit, after the source has begun to operate. This 
permit is an enforceable compilation of all enforceable terms, 
conditions, and limitations applicable to the source, and is designed 
to improve compliance by clarifying what facilities must do to control 
air pollution. EPA regulations implementing Title V are codified at 40 
CFR part 71 for permits issued by EPA or its delegatees, and at 40 CFR 
part 70 for permits issued by states and local agencies pursuant to 
approved programs. A Title V permit is valid for no more than five 
years and may be renewed in five-year-increments.
    MPLX, LP operates a facility in Uintah County, Utah, known as the 
Wonsits Valley Compressor Station. The owner of the facility is 
Andeavor Field Services, LLC. At the facility, natural gas is 
dehydrated and compressed before being routed offsite through a 
pipeline. The facility operates two control devices to control the 
emissions from the dehydration unit. In 2013, EPA issued an initial 
Title V permit for the Wonsits Valley facility pursuant to 40 CFR part 
71. On May 13, 2020, EPA issued a renewed Title V permit to Andeavor 
and MPLX. See Title V Permit to Operate No. V-UO-000005-2018.00, Docket 
ID: EPA-R08-OAR-2018-0349. By its own terms, and consistent with 40 CFR 
71.11(i)(2), most provisions of the renewal permit became effective on 
May 13, 2020. But on May 13, 2020, MPLX petitioned the EPA's 
Environmental Appeals Board (EAB) to review certain terms and 
conditions of the May 2020 Title V permit. Consequently, under 40 CFR 
71.11(i)(2)(ii), the effective date of the contested terms and 
conditions of the permit was delayed.

III. Effect of This Action

    On September 2, 2020, the EAB denied MPLX's petition for review. 
See In re MPLX, Permit No. V-UO-000005-2018.00, CAA Appeal No. 20-01 
(EAB, Sep. 2, 2020) (Order Denying Review). Following the EAB's action, 
pursuant to 40 CFR 71.11(l)(5)(i), EPA issued a final permit decision 
as to the contested portions of the permit on September 16, 2020. All 
contested conditions of Title V Permit No. V-UO-000005-2018.00, as 
issued by EPA on May 13, 2020, were therefore final and effective as of 
September 16, 2020. Except as provided in the permit, the final Title V 
permit will expire on September 16, 2025.

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