But activists, who claim incineration of medical waste is not necessary, say they want the company out of Utah.
"They cheated the books and are under investigation criminally. Why we do we trust this company? Why are we bending over for them? It says a lot about the governor," said Alicia Connell, a founder of Communities for Clean Air and former Stericycle neighbor.
Connell was referring to state and federal enquiries into Stericycle's operations. In May, the state Division of Air Quality issued a notice of violation alleging Stericycle's toxic emissions exceeded limits set in its permit and that the company manipulated stack test results.
Stericycle is formally contesting the allegations, which could result in a fine and other sanctions.
Meanwhile, company officials say the incinerator's emissions are far below limits specified in its permit, which expires next month. As part of its permit renewal, they propose spending $1.5 million to replace its back-up generator and emission control equipment.
Selin Hoboy, Stericycle's vice president of legislative and regulatory affairs, said she is "dumbfounded" by the activists' renewed opposition, noting that company is legally able to stay put in the Foxboro neighborhood.
"I don't think we can do anything to make them happy," Hoboy said. "We thought this would be a positive change for us to take the step to move incineration operations to an area that's more conducive."
Stericycle limits incineration to non-hazardous pharmaceuticals, trace chemotherapy and pathological waste, or body parts and tissues, according to Hoboy. Other forms of waste are shipped out of state to autoclaves, a steam-based technology that is not effective for rendering drugs safe, she said.
But Connell contends the proposed incineration site is just upwind of Salt Lake's airshed, whose load of particulate pollution violates federal standards.
"By moving them to Tooele, I hope they don't think it's out of sight, out of mind. We don't want to make our problem into someone else's," she said. "It's still our problem."
Utah law requires both the Legislature and the governor to sign off on the siting of any new solid-waste disposal facility, so Herbert remains in a position to kill the deal. Stericycle must also secure an new operating permit under Title V of the Clean Air Act, expected to be a multiyear process.
Communities for Clean Air and other Utah environmental health advocacy groups plan to protest at the Capitol outside the governor's office in the next two weeks.
"We want the governor to talk to us. We want him to recognize this is a big issue," Connell said.
