Administration finalizes weakening of coal-plant rules

It alters Obama-era policy on reducing polluted wastewater

BILLINGS, Mont. — The Trump administration on Monday finalized its weakening of an Obama-era rule aimed at reducing polluted wastewater 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.

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.

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 official 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.

“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.

The rules also carve out an exception for a plant operated by the nation’s largest public utility, the Tennessee Valley Authority. The plant in Cumberland City, Tenn., near the Kentucky border, accounts for up to one-sixth of the wastewater released in the country from cleaning out coal plant flues, millions of gallons per day more than any other plant.

The 2015 rule would have required compliance between 2018 and 2023 and was projected to have yielded roughly $500 million in public health and environmental benefits by reducing pollution by 1.4 billion pounds annually.
