Stellantis is committed to providing the community with quarterly air monitoring updates via the dedicated ambient air monitoring station on the Detroit Assembly Complex – Mack property. It collects temperature, wind speed, and wind direction data, along with air concentrations of Particulate Matter less than 2.5 microns (typically referred to as PM 2.5), and Nitrogen Oxides, including Nitrogen Dioxide (or NO2).

For the fourth quarter 2021, the PM 2.5 and NO2 testing results indicate that the local air quality is well within the federal National Ambient Air Quality Standard, established by the U.S. Environmental Protection Agency to help protect the health of sensitive populations such as persons with asthma, children and the elderly.

In addition, a monthly test is conducted for the presence of volatile organic compounds, or VOCs, from March through October. These air samples are collected and tested at an independent, certified analytical laboratory.

Shown on the table is the highest concentration measured in at least one sample last year. The Michigan Air Toxics Screening Levels shown indicate what is considered safe by the state. In every case, the highest concentration of each of the constituents detected is well below (or better than) the level considered to be safe.

The data continue to demonstrate that the air in the community surrounding the Mack Assembly Plant is safe.
