  • 1001 S. Oakwood Blvd.
    Detroit, MI 48217

    State Registration No.: A9831

    Marathon submitted an application (APP-2024-0053) for a Permit to Install (PTI) requesting the following changes on 3/20/2024.  It replaces withdrawn application APP-2023-0146.

    1. Removal of the throughput limits from the storage tanks in Flexible Groups FGCRUDETANKS-S1, FGNAPHTHATANKS-S1, and FGGROUPS-S1 as well as increasing the coke drum cycling limit in (EU70-COKER-S1) from 487 to 500 cycles per 12-month rolling time period so the refinery can operate at its capacity. These requests do not require physical changes to the refinery.
    2. Changes to make up for potential increases in emissions due to removal of the throughput limits. Putting these in the permit makes them legally enforceable. The changes include:
      • Replacing the Naphtha Hydrotreater Unit heaters (Emission Units include EU16- NHTSTRIPREBOIL-S1 and EU16-NHTCHARHTR-S1) with new heaters equipped with ultra-low oxides of nitrogen (NOx) burners to reduce releases of NOx to the atmosphere.
      • Removing the crude flare (EU-CRUDEFLARE-S1) from service.
      • Installing a dome over a gasoline storage tank EUTANK110-S1 to reduce releases of volatile organic compounds (VOCs) to the atmosphere.
      • Expanding the leak detection and repair program to cover more of the refinery to limit fugitive releases.
    3. Criteria pollutant emission limits (emission caps) that are lower than their current permit limits for NOx, sulfur dioxide (SO2), carbon monoxide (CO), particulate matter less than 10 microns in diameter (PM10), particulate matter less than 2.5 microns in diameter (PM2.5), volatile organic compounds (VOCs), sulfuric acid mist, hydrogen sulfide (H2S), and total reduced sulfur.
    4. Extension of perimeter air monitoring program at the facility for three years after issuance of the requested PTI.
    5. Inclusion of language from USEPA Consent Decree 12-11544.

Withdrawn Permit Applications

Permit Applications Related to SO2 State Implementation Plan - Wayne County

These permit applications are necessary to meet specific federal requirements to include sulfur dioxide (SO2) limits from the Federal Implementation Plan into Michigan's State Implementation Plan. Although the limits associated with these applications are already contained in the Federal Plan, they need to be incorporated into the facility permits to complete the state’s obligations. These are considered one action and were opened for comment when draft conditions were complete.  The three air permits to install (PTIs) were approved on 9/26/2023.
