IPL has filed petitions with the Indiana Utility Regulatory Commission to install $100 million worth of pollution controls at Petersburg, a move it says will allow it to meet strict environmental regulations.
The owners of more than 20 polluted industrial sites in Indianapolis are hiding behind the legal protections of a state-run voluntary program to delay cleanup, Mayor Greg Ballard alleges in a letter to state regulators.
The Truck and Engine Manufacturers Association, which represents Indiana-based Cummins Inc. and other engine manufacturers, said the proposal represents a chance to modernize how the agency oversees big-rig emissions.
The plan would give states broad authority to determine how to restrict carbon dioxide and other greenhouse gas emissions that contribute to global warming. It also would let states relax pollution rules for power plants that need upgrades.
The Trump administration announced Thursday it is doing away with a decades-old air emissions policy opposed by fossil fuel companies, a move that environmental groups say will result in more pollution.
