Four environmental groups are getting heat from supporters of an effort to restart the Healy Clean Coal Plant.

The Fairbanks Daily News-Miner says more than 100 people showed up Wednesday at the headquarters of the Northern Alaska Environmental Center in Fairbanks to show their support for the project. They carried signs reading "Support Working People" and "No to Environment Wackos."

They were met by an equal number of opponents with signs reading "Climate Change is Real" and "Stop Subsidizing the Gold Mines on our Backs."

At issue was a decision by the Northern Alaska Environmental Center, the Denali Citizens Council, the Sierra Club and the National Parks Conservation Association to appeal an air quality permit issued for the power plant.
