Facility Overview
The Jefferson North Assembly Plant (JNAP) opened in 1991 and remains one of Detroit’s largest automotive facilities. It produces the Jeep Grand Cherokee and Dodge Durango SUVs and sits between Jefferson Avenue and Conner Street on Detroit’s east side. JNAP borders dense residential neighborhoods and shares supplier routes with the newer Mack Assembly Plant one mile north.
The property is owned and operated by Stellantis N.V., formed in 2021 from the merger of Fiat Chrysler Automobiles and PSA Group. Its operations include paint booths, solvent storage tanks, and high-temperature ovens regulated under state and federal air permits.
Environmental Record
Between 2019 and 2024, the EGLE Air Quality Division issued six violation notices to JNAP for recordkeeping and emission-control deviations under its Title V permit. Infractions included failures to log VOC usage, opacity exceedances under Rule 336.1301, and late compliance submissions. EGLE assessed ≈ $25,000 in stipulated penalties.
While smaller in scale than the odor cases at Mack Assembly, these notices reflect ongoing monitoring and recordkeeping issues. EPA ECHO facility records show periodic non-compliance status and multiple state inspections.
Media outlets including BridgeDetroit and Detroit Free Press have covered these air-quality violations and community responses.
Community Impact
Jefferson North borders neighborhoods identified by EPA EJScreen as high pollution-burden and economically vulnerable. Residents along Conner and Jefferson have reported paint and solvent odors during certain wind conditions, and truck traffic serving the plant adds noise and road wear.
BridgeDetroit and Planet Detroit documented how nearby schools and homes face elevated exposure risks from industrial corridor operations. While the plant provides thousands of jobs, residents continue to push for better emission controls and real-time air monitoring.
Status & Sources
As of October 2025, Jefferson North remains fully operational under EGLE oversight with no outstanding consent orders. Routine Title V inspections and permit renewals are scheduled for 2026.
