MAT Asphalt’s permit expired on July 2nd. The IEPA has decided to allow them to keep operating while they apply for a 10 YEAR PERMIT. (It was originally a 5 year permit application, but the IEPA decided to allow them to change it to a 10 year application – again, without offering formal notice to the community).

Several public officials have already committed to opposing the permit, including State Sen. Tony Munoz and State Rep. Theresa Mah. Over 2,000 people have signed a petition demanding that the MAT Asphalt Plant be shut down and relocated. Join us!



In the case of MAT Asphalt, their permit requires them to not create an odor nuisance. Reporting odor nuisances is a critical part of holding them accountable to their permit. Make complaints as soon as possible after detecting an odor and provide information in as much detail.
