WASHINGTON: Hundreds of coal industry workers and supporters gathered Tuesday in front of the U.S. Capitol as a parade of coal-state lawmakers assailed the Obama administration for waging a “war on coal” with new environmental rules.

Last month, the Environmental Protection Agency proposed standards aimed at curbing carbon dioxide emissions, a major contributor to global warming, according to most climate scientists. However, the rules would make it nearly impossible to build new coal-fired power plants without expensive and unproven technology to capture carbon dioxide and pump it underground.

On Tuesday, miners from several coal-producing states, some wearing yellow hard hats and carrying signs that said “Impeach Obama,” cheered as lawmakers of both parties and other speakers criticized the administration.

“I blame one man,” Sen. Rand Paul, R-Ky., told the crowd. “President Barack Obama.”

Rep. Andy Barr, R-Ky., blasted “unelected, unaccountable bureaucrats” at the EPA. He challenged Obama to come to eastern Kentucky, where more than 6,000 coal-related jobs have vanished in the past two years.

At a House of Representatives Energy and Commerce Committee hearing after the rally, witnesses described coal-dependent communities in crisis.

Albey Brock, the top elected official of Bell County in southeast Kentucky, told the Energy and Power Subcommittee that eastern Kentucky depended on coal more than Detroit depended on the auto industry. But the county of 28,000 has a 14 percent jobless rate, compared with 8 percent statewide and 7 percent nationwide.

“I cannot imagine the EPA calculated the human impact of their decisions,” Brock told lawmakers.

A bill co-sponsored by Sen. Joe Manchin, D-W.Va., and Rep. Ed Whitfield, R-Ky., would ease the EPA rules that Whitfield called “unworkable.”

However, coal isn’t threatened just by EPA regulations. The deepest recession since the Great Depression reduced demand for electricity, and the market hasn’t experienced a strong recovery.

An abundance of cheaper natural gas unlocked by hydraulic fracturing has made coal less attractive to domestic utilities. Coal generates less than 40 percent of the nation’s electricity, down from half a decade ago. Natural gas, meanwhile, has increased its share from 20 percent to about 30 percent.

Renewables such as wind and solar have steadily increased their share of the energy market, according to the U.S. Energy Information Administration.

“This isn’t something the government did,” said Rep. Henry Waxman, D-Calif., the ranking member on the House Energy and Commerce Committee. “This is something the market dictated.”
