U.S. finalizes coal plant pollution rollback
BILLINGS, Mont. — The Trump administration on Monday finalized its weakening of an Obamaera rule aimed at reducing pollution from coal-burning power plants that has contaminated streams, lakes and underground aquifers
The change will allow utilities to use cheaper technologies and take longer to comply with pollution reduction guidelines that are less stringent than what the agency originally adopted in 2015.
It’s the latest in a string of regulatory rollbacks for coal power under Trump — actions that have failed to turn around the industry’s decline amid competition from cheap natural gas and renewable energy. Power utilities including Southern Co., Duke Energy, and Xcel Energy had lobbied for the relief.
The latest rule change covers requirements for cleaning coal ash and toxic heavy metals such as mercury, arsenic and selenium from plant wastewater before it is dumped into waterways. Plant operators also often rely on water to flush toxic coal ash from the bottom of furnaces. For more than a decade, environmentalists have warned the practice imperils American waterways.
Utilities are expected to save $140 million annually under the changes, which Environmental Protection Agency Administrator Andrew Wheeler said in a statement would protect industry jobs in part by using a phased-in approach to reducing pollution.
But environmentalists and a former EPA officials warned the move will harm public health and result in hundreds of thousands of pounds of pollutants annually contaminating water bodies.
The new rule largely exempts coal plants that will retire or switch to burning natural gas by 2028.
Coal plants are responsible for as much as 30 percent of all toxic water pollution from all industries in the U.S. In the Southeast, that number is even higher.
“This rule is going to continue to let these coal-fired power plants pour these toxics into the nation’s rivers and streams, contaminating drinking water and fisheries for 2.7 million people,” said Betsy Southerland, who was the science director in the EPA’s water office before retiring in 2017.
The estimate of people impacted is from the analysis that was done for the Obama-era rule, she said.
The revised rule is expected to affect 75 out of 914 coal power plants nationwide, compared to more than 100 plants affected by the 2015 rule. That’s in part because coal power usage has dropped dramatically over the past decade and many plants have been shuttered.
America’s Power, a trade organization that advocates on behalf of coal-fueled electricity, said the rule was good news and that the Obama-era rule could have forced the closure of coal plants needed to keep the power grid reliable.
“We support rules that protect the environment and human health, and we are optimistic the revised rule will not adversely affect the electricity grid,” the group said in an emailed statement.
An attorney for Earthjustice, Thom Cmar, said the environmental law firm plans to challenge the rule in federal court.
