The U.S. Environmental Protection Agency was wrong to determine Michigan met federal health and environmental standards for ozone pollution or smog in the Detroit area in 2023, a federal appeals court judge has ruled.
U.S. 6th Circuit Court of Appeals Judge Helene White on Dec. 5 issued a split decision in a case about how environmental regulators measured Detroit air quality in 2022, when wildfire smoke drifted over Detroit and affected the air quality monitor readings for a few days in June.
Michigan considered those days “exceptional events” because of the wildfire smoke and didn’t include the high ozone pollution readings in its calculation to the EPA.
With those days tossed, the state was able to argue in 2023 that Michigan met federal air quality standards for ground-level ozone pollution. The seven-county Metro Detroit region had previously been out of compliance with the ozone standards.
The Sierra Club sued, arguing the wildfire smoke did not meaningfully change ozone readings and that the Michigan Department of Environment, Great Lakes and Energy failed to analyze how local pollution sources contributed to the ozone levels on those days. The environmental advocacy group also challenged the EPA’s finding that the region met federal standards for ozone pollution.
White determined the exceptional events designation was appropriate, siding against the Sierra Club in deciding the EPA and EGLE correctly analyzed the smoke’s impact on ozone readings in June 2022.
She sided against EPA in deciding the EPA was wrong to put Michigan back into attainment for ground-level ozone without Michigan adopting control measures that would cut volatile organic compounds, which contribute to ozone pollution.
EPA determined the Detroit area was out of attainment for ground-level ozone on April 13, 2022. Michigan regulators did not impose control technologies for ozone-causing pollutants by the deadline in early 2023. Instead, they asked EPA to redesignate the area as in attainment with the air quality rules.
Michigan was obligated to implement control technologies even though it had submitted a redesignation request, White said in her order. Control technologies include efforts to reduce volatile organic compounds from being released from manufacturing plants and industrial sources, according to EPA documents.
Sierra Club member and Detroit environmental justice activist Dolores Leonard cheered the outcome of the case.
“Without this victory, EPA’s decisions would have let Michigan avoid the rules needed to reduce pollution and keep the air we breathe safe,” Leonard said. “At a time when asthma rates are rising in Detroit, especially in Black communities, that’s unacceptable. With the backing of this federal court decision, our community will continue to push the state of Michigan to take much-needed action to relieve ozone pollution in this area.”
The Clean Air Act requires those pollution control measures to be implemented even after the EPA puts an area back into attainment to ensure the air quality remains healthy, said Nick Leonard, executive director of Great Lakes Environmental Law Center, which argued the Sierra Club’s case.
White’s order means the EGLE will have to reapply for the attainment of the ozone standard, Leonard said.
“At the very least, I would say they have to correct the legal deficiency, which was that they didn’t enact the pollution control rules that are typically required for areas that are in non-attainment for this long,” he said.
The EPA is reviewing the decision, its press office said. The office did not respond to a question about whether it would ask Michigan to adopt volatile organic compound control measures as a result of White’s decision.
The EGLE also is reviewing the ruling, spokesman Dale George said.
“While EGLE was not a party to the case and is not able to speak in detail about the legal outcome, we were encouraged that the court supported the use of exceptional events demonstrations and acknowledged the sound science behind EGLE’s determination that the Detroit area met the health-based ozone standard,” George said.
Leonard said he was disappointed but not surprised that White ruled against the Sierra Club’s arguments that EGLE and the EPA did not correctly account for wildfire smoke’s impact on ozone readings in 2022.
That issue is going to plague communities as climate change causes northern wildfires to become more common and kick smoke into Michigan, he predicted.
“If we start to essentially cut out bad air quality days because of the claim they were partially influenced by wildfire smoke … , you create this disconnect between the regulatory systems that are meant to protect people and the actual air pollution that people are breathing,” Leonard said.

St. Hubert pastor discusses the Archdiocese of Detroit’s restructuring
The Rev. Douglas Bignall of St. Hubert Catholic Church in Harrison Township discusses the ongoing restructuring effort by the Archdiocese of Detroit on Tuesday, May 19, 2026.
The list of churches targeted for the possible stoppage of weekend Masses has grown to at least 58 parishes across southeast Michigan, according to the latest proposed models the Archdiocese of Detroit had released as part of its major restructuring process through Friday.
At least 22 parishes under the first round of proposed models wouldn’t hold weekend Mass. The archdiocese has been divided into 15 planning areas, or geographic areas, and three or four models are being proposed for each planning area, said the Rev. Mario Amore, executive director of parish renewal for the Archdiocese of Detroit.
The archdiocese has been holding listening sessions with parishioners this spring as part of its restructuring plan to get reactions.
The models have different proposed groupings of parishes, in which a grouping would share a pastor and potentially other priests. In some cases, selected churches in the grouping would no longer hold Sunday Mass.
The Archdiocese of Detroit released on May 22 and this past week the model proposals for another five planning areas, including areas of Macomb County, Oakland County and Detroit. Around 36 more parishes would no longer hold Mass in the future under the latest proposals.
Bunches of churches in Detroit would be affected, while four parishes in Troy and three parishes in Clinton Township wouldn’t have Saturday Vigil Mass or Sunday Mass under each of the proposed models presented for their planning areas.
Archdiocese of Detroit spokesperson Holly Fournier said the archdiocese has heard a wide range of reactions about the proposed models, which is “understandable given how personal parish life is for people.”
“Some pastors and parishioners are hopeful about opportunities for stronger collaboration and renewed ministry, while others are experiencing more uncertainty and concern, especially in places where one or more models suggest a parish might no longer host weekend Masses in the future,” she said.
Fournier emphasized that the models are “draft models” and aren’t final decisions.
The models for the final six planning areas will be released in June, according to the restructuring website.
The models are part of the archdiocese’s biggest restructuring plan in years. Announced last fall, Archbishop Edward Weisenburger said the archdiocese can’t maintain the roughly 200 existing parish buildings it has and is working to “right-size” the archdiocese, along with its personnel and financial resources.
Fournier said the draft models were developed by priests earlier this year and are being presented in listening sessions as proposals “meant to spark broader consultation with the faithful.” Each parish in the archdiocese is holding listening sessions this spring or early summer.
In other dioceses that have undergone restructuring processes like the Archdiocese of Detroit’s, as many as 20-40% of the initial models were changed as a result of parishioner feedback, Fournier said.
“That is why it is so important for Catholics to attend their parish listening sessions to view these models and provide their honest feedback, so informed adjustments can be made where necessary,” she said in an email.
One of the most heavily affected groupings is Planning Area 1, which includes west Detroit. Ten of its 13 parishes would not have Saturday Vigil Mass or Sunday Mass in at least one of the model plans. They include Christ the King, Presentation/Our Lady of Victory, SS. Peter and Paul (Jesuit), SS. Peter and Paul (Westside), St. Charles Lwanga Church, St. Mary of Redford, St. Moses the Black Parish, St. Peter Claver Parish, St. Scholastica and St. Suzanne-Our Lady Gate of Heaven, all of which are in Detroit.
Planning Area 9, which includes southeastern Oakland County, has between 15 and 19 parishes, depending on the model. Ten of the parishes wouldn’t hold weekend Mass in at least one of the models. Four of them are in Troy.
They include St. Lucy in Troy, St. Elizabeth Ann Seton in Troy, Christ Our Light in Troy, St. Thomas More in Troy, St. Owen in Bloomfield Township, Our Lady of La Salette in Berkley, Our Mother of Perpetual Help in Oak Park, St. Justin-St. Mary Magdalen in Hazel Park, St. Vincent Ferrer in Madison Heights and Divine Providence in Southfield.
Planning Area 10, which includes all of northern Oakland County and parts of western Oakland County, has 19 to 22 parishes, depending on the model. Seven would stop holding weekend Mass in at least one of the models, including St. Benedict in Waterford Township, St. Thomas More in Troy, Sacred Heart in Auburn Hills, St. John Fisher Chapel University Parish in Auburn Hills, St. Perpetua in Waterford Township, St. Rita in Holly and Prince of Peace in West Bloomfield Township.
Planning Area 12, which includes parts of southern and eastern Macomb County, has 16 parishes. Four Warren parishes and three Clinton Township parishes would stop holding Mass under the draft models.
St. Louise de Marillac in Warren wouldn’t hold Saturday Vigil or Sunday Mass in two of the three draft models presented by the archdiocese. Six other parishes would not hold weekend Mass in only one of the models, including St. Louis in Clinton Township, San Francesco in Clinton Township, St. Ronald in Clinton Township, St. Martin de Porres in Warren, St. Faustina in Warren and St. Mark in Warren.
Planning Area 13, which includes areas of central and northern Macomb County and a parish in Troy, has 14 or 16 parishes, depending on the draft model. Three parishes in the planning area wouldn’t have weekend Mass under at least one of the models: St. Jane Frances de Chantal in Sterling Heights, St. Matthias in Sterling Heights and SS. John and Paul in Washington Township.
Amore said that if a church stops holding Sunday Mass, parishioners are encouraged to worship at other churches in their “pastorate,” which is a grouping of parishes overseen by a pastor. In the long term, the church building might close, or other sacramental celebrations might take place there, such as weddings and baptisms, he said.
The parish’s buildings could also be repurposed for other uses, such as religious education classes.
Fournier said the proposed models are meant to “foster discussion and discernment.”
“We encourage Catholics to stay engaged in the process, share their feedback honestly, and remember that the goal is not simply organizational change, but ensuring vibrant Catholic communities for future generations,” she said.
