In response to a growing community outcry against an incinerator that had been burning medical waste and non-medical wastes from several states, industry giant Stericycle permanently closed their controversial incinerator on the Gila River Indian Community reservation in Arizona in 2002. 

Gila River Indian Community tribal members, led by Lori Riddle, launched a campaign to evict the incinerator from tribal lands in 2002 after learning about the toxic emissions from the facility. Located at the tribe's Lone Butte Industrial Park on the reservation near Chandler, Arizona, the incinerator emitted dioxin, mercury and many other toxic chemicals.

Tribal members formed the Gila River Alliance for a Clean Environment (GRACE) to successfully campaign against the incinerator and other environmental hazards on tribal lands.  GRACE’s work continues today against the Romic hazardous waste recycling facility.
