Giving industry incentives to use Utah's low-sulfur coal might also help win the international fight to eliminate acid rain, according to Rep. Howard C. Nielson, R-Utah.

So he sent letters to John Sununu, White House chief of staff, and to William K. Reilly, administrator for the U.S. Environmental Protection Agency, asking for a change in clean air rules that would favor the use of more low-sulfur coal.Nielson explained, "The original, 1971 mandate simply set standards that major industrial coal-burning facilities had to meet. And many companies found they could meet those standards by using low-sulfur coal - such as we have in Utah - rather than to install costly scrubbers to clean sulfur from their emissions.

But in 1979, the next act eliminated any element of choice and required the scrubbing of 90 percent of the sulfur content from whatever coal might be used, he said.
