This IDEM press release announced a public hearing for Monday, May 17th. Note that the link to IDEM air permits given in the press release is wrong; here is the correct link. I had difficulty finding the correct permit even after locating the site, so here is the direct link to the 149-page draft permit.
According to this story in today's Indianapolis Star:
State and city environmental officials decided this week to extend the public comment period to allow residents to make a case for delaying the permit until an environmental audit of the facility is completed.Posted by Marcia Oddi at May 21, 2004 08:19 AM
