"We are not a partner in that project," said spokesman Greg Hardy. He had no further comment.
Nonetheless, some of those present promised by any means necessary to halt the operations of the planned tar sands mine in the Book Cliffs near P.R. Springs in Uintah and Grand counties
The rally was sponsored by the 2-year-old Utah Tar Sands Resistance organization. Also on hand were representatives from a handful of environmental organizations who decried tar sands as "dirty energy."
Tar sand is made up of sand, clay a heavy black viscous oil, called bitumen. Tar sands can be mined and processed to extract bitumen that can them be refined into oil.
One of the organizers Saturday's rally, Bart Tippetts, said because tar sands contains high levels of sulfur, lead and other carcinogens, refining it spews more poisons into Salt Lake Valley. In January, Salt Lake City earned the distinction of having the nation's dirtiest air.
Another Resistance member, Raphael Cordray, said the group wanted to bring public attention to the Utah's tar sands project because the state government is too lax when it comes to environmental regulations.
"The state of Utah is business friendly," she said. "It has put the fossil fuel industry ahead of the health of the people of Utah."
A number of protesters pointed to the recent Willard Bay Chevron pipeline spill and two others that have occurred in Salt Lake City within the past three years as evidence that the oil company is not a good neighbor.
Ty Markam, from the newly formed Mormon Environmental Stewardship Alliance, said her young group already has about 1,500 members, who are standing up for clean air and a clean environment.
By nature, she said, Mormons are not street protesters. "But the LDS people are saying enough is enough."
Will Munger, who spearheads an organization called Canyon Country Rising Tide, said in June he will host a training camp for people interested in blockading the P.R. Springs tar sands development.
He led the protesters in a chant: "All night, all day, tar sands blockade."
Salt Laker Sandra Biel said she attended the protest because she is fearful of what Utah's dirty air is doing to her health and that of her children.
"My hope is that people will see us on the news and check out and see what is happening with tar sands," she said. "My hope is they will stop the tar sands project in Utah."
