About 100 people turned out for hearings that lasted more than four hours, and about half of them commented on a request to change the state's plan for controlling PM 10 pollution mostly dust and large exhaust particles to allow for the expansion, which Kennecott has dubbed the "Cornerstone Project."
The second request would allow Kennecott to update its facilities under the New Source Review standards in the Clean Air Act. The changes are required because additional pollution is expected as Kennecott moves up to 260 million tons of dirt and rock each year, up from the 197 million tons currently allowed.
Changes to these permits are the first of about two dozen the company is expected to bring before the state's environmental regulators for the expansion. Comprising the Utah operations of the British-Australian Rio Tinto Group, Kennecott has about 70 state environmental permits.
Nearly 30 people criticized regulators for considering allowing more pollution and Kennecott for being the county's single biggest polluter. They noted Salt Lake County already fails to meet federal standards for PM 10, fine-particle soot called PM 2.5 and ozone.
Marion Klaus, chair of the Sierra Club of Utah, noted that Salt Lake County exceeded EPA standards on 51 days last year. She also noted Kennecott's parent company racked up $14.3 billion in profits last year.
"The only thing truly healthy [about Kennecott] is the profit they make," she said, adding that locals and their children "pay the cost" while faraway shareholders enjoy the profits.
"We have in fact fouled our own nest," Klaus said, "and we need to clean it up and not permit fouling it up anymore."
Provo resident Carol Walters also urged regulators to reject the company's requests because poor air quality damages health."A job isn't much use," she said, "if you can't breathe."
Alan Anderson, president and CEO of the ChamberWest business association, was among nearly two dozen speakers who urged approval of the requested changes without delay.
Among the facts cited by supporters: Kennecott employs about 2,400 people and pumps $900 million into the economy each year. And it has spent nearly $1 billion on cleanup and reducing the environmental pollution caused by its operations.
Rob Campbell, of Kennecott supplier Wheeler Machinery Co., concluded: "My sincere hope is that state regulators will consider the vital role Kennecott plays in the local economy, Kennecott's leading role in improving previously mined lands and improving air and water quality, and the many families whose lives are better because Kennecott is here."
