The battle between Gary Sayers and officials has been going on for months. EGLE and Detroit officials said Sayers ignored repeated calls about getting the work done over the last several months. Any clearing of debris on the property helps facilitate our ability to assess the site for possible contamination.Sayers is also battling state and city leaders in Madison Heights, where green ooze seeped from his building and onto I-696.
