Kim Biggs, an Illinois EPA spokeswoman, said agency officials granted Trump Tower a four-year permit in 2013 and proposed renewing it this year based on limited information from building representatives. But the agency is planning to revise its draft “to address a number of issues” regarding the skyscraper’s cooling intakes, Biggs said, and will hold a public hearing to discuss the changes. “Your references to the January 2018 draft permit may no longer be relevant once the new draft permit is put to notice,” she said in an email.
