Air Quality Information

Stellantis, also known as FCA or Fiat Chrysler America, operates automotive manufacturing at numerous locations on the east side of Michigan. The making of a car is a complicated process that requires many steps and thousands of parts.

Not every location makes every part of the car as different machines and expertise is needed to finish the car. Many locations have processes with air emissions and must comply with air quality rules and regulations, have air permits, and have regular inspections by EGLE staff. This webpage lays out the different locations and provides links and information about each location.

Facility Information

Detroit Assembly Complex

The Detroit Assembly Complex consists of the Mack Assembly and the Jefferson North Assembly Plants. The Mack Assembly plant has recently been converted from an engine plant to an assembly plant. Operations at these two locations now primarily include painting and assembly. Information is available on inspections, stack test, violation notices, and the company's response to those violations. The company also has several air Permits to Install rolled into a Renewable Operating Permit and an application under review.

Information

    • Autumn 2021: Recent compliance activity has included September 20, 2021, October 20, 2021, and November 3, 2021 violation notices. These violations were related to odors and improperly installed equipment.
    • November 18, 2021: EGLE has started escalated enforcement against Stellantis related to violations above.
    • November 22, 2021: At EGLE's request, the United States Environmental Protection Agency did mobile air monitoring on November 16 and 17 using their Geospatial Measurement of Air Pollution (GMAP) vehicle. Results of the monitoring and the evaluation can be found in their GMAP Report for November 19, 2021. Please note that canister samples collected during this monitoring are still being analyzed by laboratory staff. These results will be added as soon as they become available.
    • November 22 & December 8, 2021: The Michigan Department of Health and Human Services (MDHHS) contractors conducted air sampling near the facility. The samples from November 22 have been analyzed by laboratory staff and the results have been provided to MDHHS. The samples collected on December 8 are being analyzed by laboratory staff.
    • December 21, 2021: Stellantis notified EGLE that corrections has been made to the assembly line ductwork. The ductwork is now venting emissions to the control devices, as the air permit required. EGLE and MDHHS continue to investigate odors and evaluate air sampling results.
    • January 11, 2022: Stellantis has submitted the Detroit Assembly Complex Mack Odor Investigation, Analysis, and Mitigation Plan as part of their response to the violation notices. EGLE is reviewing the plan.
    • January 12, 2022: EGLE will host an on-line community meeting to talk with the public about air sampling activities around the Stellantis - Detroit Assembly Complex in Detroit, Michigan. The online meeting will be on Thursday, January 27, 2022, at 6:00 PM EST. The meeting will be recorded and the recording posted soon. A link will be provided when it is available.
    • January 27, 2022: On-Line Community Meeting
    • March 2022: EGLE continues to respond to and evaluate complaints. An additional violation notice was issued for objectionable odors on March 24, 2022. EGLE is working through the escalated enforcement process, partnering with the USEPA, and consulting with MDHHS on matters related to evaluation of public health. Additional information will be posted as it becomes available.
    • May 2022: Recent compliance activity has included:
      • The submittal of an air permit application by Stellantis requesting the installation of a new air pollution control device, called a Regenerative Thermal Oxidizer or RTO and changes to existing exhaust equipment.
      • A May 20, 2022 violation notice for objectionable odors.
      • Continuing progress on the escalated enforcement action.
      • Final planning for additional onsite air sampling to help further evaluate sources of potential odors.
    • July 2022: On-site air sampling on the Stellantis property was completed in early June. This sampling was done to further evaluate sources of potential odors. Unfortunately, due to samples being damaged by high temperatures during shipping, the samples were ruined and could not be analyzed. Because the samples were damaged, the results would not be valid. Staff at EGLE and Stellantis were very displeased with this news and are working hard to redo the sampling. The results of sampling can take four to six weeks and will be shared once they are received. EGLE continues to work through the air permitting and enforcement process. Progress in both these areas is being made.
    • August 2022:  Work on the enforcement action is moving forward and is anticipated to go out for public notice and comment on the Mack Plant in fall 2022.  The public notice and comment period will include a virtual information session and public hearing.  Comments will be accepted at any time during the comment period.  More information will be shared at Michigan.gov/EGLEAirPublicNotice (choose “Compliance / Consent Orders” as it becomes available). Repeat sampling is still being planned for fall 2022. EGLE will share results of this sampling when received.
    • September 2022:  EGLE is taking enforcement action and is seeking public input on a proposed consent order. The proposed consent order contains a monetary penalty, a compliance plan, penalties for future violations, and two supplemental environmental projects (SEPs). Comments can be submitted at any time during the comment period ending on November 2, 2022.  An informational session and public hearing will be held on October 19, 2022, at 6:00 PM EDT.
    • October 2022:  View the recording of the October 19, 2022, information session and public hearing on the enforcement action.
    • November 2022:  A violation notice was issued on November 14, 2022 to the JNAP facility for exceeding an emission limit in their permit for the month of September 2022. The facility has 21 days to respond with a plan to return to compliance. The company's response will be posted once it is received.
    • December 2022:  The consent order between EGLE and the FCA Mack Plant has been finalized with changes.  These changes include: January 2023:  EGLE has started escalated enforcement against the JNAP facility related to the November 14, 2022 violation notice for excess emissions.  The response to the violation notice was received on December 5, 2022 with additional information sent on December 21, 2022.  Escalated enforcement can take time.  More information will be shared as it becomes available.
    • March 2023: EGLE's AQD did limited onsite air sampling on October 14, 2022.  The purpose of the sampling was to determine whether community odor complaints were linked to specific air pollutants exiting the building at points other than the stacks, including doorways, vents, openings, or storage piles. Full results are available in the Detroit Assembly Complex Stellantis On-Site Sampling Report.
    • May 2023: A violation notice was issued on May 11, 2023 for odors following community complaints and an odor investigation by AQD. The facility has 21 days to respond with a plan to return to compliance. The company's response will be posted once it is received.
    • June 2023: As a result of the May 11, 2023 violation notice issued for odors following community complaints and an odor investigation by AQD, the company is required to pay a stipulated penalty of $5,000 by July13, 2023 as required by the 2022 consent order.
    • July 2023: The company began operation of the second regenerative thermal oxidizer (RTO2) on July 5. EGLE staff did an inspection of RTO2 on July 17 and determined it is installed and operating as required by the existing consent order. The permit associated with this equipment is being drafted and will contain further requirements for testing, monitoring, and recordkeeping. EGLE staff will continue to be responsive to community concerns and do additional investigations when warranted.
    • December 2023: EGLE is seeking public input on a proposed consent order. The proposed consent order contains a compliance plan, a monetary fine, and fines for future violations. Comments may be submitted at any time during the comment period ending on January 23, 2024. An online informational session and public hearing will be held on January 9, 2024, at 6:00 PM EST. The meeting will be recorded. A link to the recording will be provided when it is available.
    • February 2024: The Stellantis Detroit Assembly Complex Mack (DACM) installed and began operating an air pollutant control device called a regenerative thermal oxidizer (RTO) in June 2023.  The control device, RTO2, was installed to reduce odors and resulted from an enforcement action. This action included mitigation measures that resolved multiple verified odor violations issued to the company.
    • March 2024: The consent order between EGLE and the FCA Jefferson North Assembly Plant has been finalized without changes. FCA has been in compliance with the 12-month rolling 4.8 lbs volatile organic compound per job emission limit since September 2023.  More details about the decision and the final Consent Order are below:

    • The purpose of RTO2 is to reduce emissions from the Topcoat 1 and Topcoat 2 clear coat observation zones on the DACM paint line.  Regardless of whether RTO2 is permitted, the standards of operation under Rule 910 require that air cleaning devices shall be installed, maintained, and operated in a satisfactory manner.
        
      As part of verifying proper operation, a stack test was done on October 12, 2023. The test was to prove that RTO2 was meeting either 95% destruction efficiency or 5 parts per million (ppm) or less of volatile organic compounds (VOCs) exiting the stack.  Staff from the Michigan Department of Environment, Great Lakes, and Energy’s Air Quality Division (AQD) were present during the testing of RTO2.  During the testing, RTO2 met the requirements and did not exceed the 5 ppm limit.
      RTO2 will be included in a revised air permit to make reductions of VOCs enforceable as a practical matter soon.
