Marathon Petroleum air quality permit hearing ‘moot’ without cumulative impact calculation: Resident

June 8, 2026

Residents of Detroit's 48217 zip code attended a public hearing to oppose air permit applications from Marathon Petroleum and MPLX that would increase industrial emissions in their already heavily polluted neighborhood. Marathon seeks to expand its rail operations for importing and exporting petroleum products, while MPLX wants to use backup pollution control equipment more frequently during fuel loading operations. State regulators acknowledge the projects would increase harmful pollutants like ozone-forming compounds and sulfur dioxide, but say they lack legal authority to deny permits based on cumulative pollution impacts or company compliance history if projects meet technical health standards.

Who is affected

Residents of Detroit's 48217 zip code
Community members with cancer and other health conditions (mentioned specifically: those in hospitals, asthma sufferers, cancer survivors, infants with asthma)
Marathon Petroleum Corp. and MPLX (facilities seeking permits)
Michigan Department of Environment, Great Lakes, and Energy (EGLE)
Southwest Detroit Community Benefits Coalition
Wayne County residents (area in nonattainment for federal ozone standards)

What action is being taken

EGLE is holding a public hearing and accepting public comment on the permit applications until June 11
EGLE is evaluating the Marathon and MPLX permit applications
Marathon is proposing to install enhanced controls on three refinery storage tanks to reduce VOC emissions by 2.6 tons per year
The Sierra Club is suing the EPA for missing the February 2025 deadline to determine whether Detroit meets federal ozone standards

Why it matters

This situation highlights a critical regulatory gap where state environmental agencies cannot consider the cumulative health burden on communities already suffering from multiple pollution sources. The 48217 zip code has some of Michigan's highest industrial pollution levels, and the area has experienced prolonged periods of nonattainment for both sulfur dioxide (13 years) and ground-level ozone. The pollutants in question—sulfur dioxide, volatile organic compounds, and nitrogen oxides—cause serious respiratory illnesses, asthma exacerbation, cardiovascular problems, and premature mortality. Detroit ranks 39th-worst nationally for ozone pollution, receiving an F grade from the American Lung Association, demonstrating the severe air quality crisis affecting this predominantly environmental justice community.

What's next

Public comment period continues until June 11
EGLE will decide whether to approve the Marathon and MPLX permit applications
If approved, Marathon would implement expanded rail operations and install enhanced controls on storage tanks
The Protecting Overburdened Communities Act, introduced by state Rep. Donavan McKinney and state Sen. Stephanie Chang in July 2025, would require EGLE to consider cumulative regional health impacts when issuing permits
The Sierra Club's lawsuit against the EPA will proceed regarding the agency's missed deadline on Detroit's ozone standards determination
