EPA to ease waste rules at coal-fired power plants

The Environmental Protection Agency plans to relax rules that govern how power plants store waste from burning coal and release water containing toxic metals into nearby waterways today, according to agency officials.

The proposals, which scale back two rules adopted in 2015, affect the disposal of fine powder and sludge known as "coal ash," as well as contaminated water that power plants produce while burning coal. Both forms of waste can contain mercury, arsenic and other heavy metals that pose risks to human health and the environment.

The new rules would allow extensions that could keep unlined coal ash waste ponds open for as long as eight additional years. The biggest benefits from the rule governing contaminated wastewater would come from the voluntary use of new filtration technology.

Trump administration officials revised the standards in response to recent court rulings, as well as to petitions from companies that said they could not afford to meet stringent requirements enacted under the Obama administration. They also reflect President Donald Trump's broader goal of bolstering America's coal industry at a time when natural gas and renewable energy provide more affordable sources of electricity for consumers.

Under the President Barack Obama-era rule, coal ash ponds leaking contaminants into groundwater that exceeded federal protection standards had to close by April 2019. The Trump administration extended that deadline until October 2020 in a rule it finalized last year.

In August 2018, the U.S. Court of Appeals for the D.C. Circuit instructed the EPA to require that companies overhaul ponds, including those lined with clay and compacted soil, even if there was no evidence that sludge was leaking into groundwater.

In a statement, EPA Administrator Andrew Wheeler said the Obama-era rules "placed heavy burdens on electricity producers across the country."

"These proposed revisions support the Trump administration's commitment to responsible, reasonable regulations," Wheeler said, "by taking a common-sense approach that will provide more certainty to U.S. industry while also protecting public health and the environment."

Under the new proposal, companies will have to stop placing coal ash into unlined storage ponds near waterways by Aug. 31, 2020, and either retrofit these sites to make them more secure or begin to close them. Unlike the Obama-era rules, the EPA will allow greater leeway and more time for operators to request extensions ranging from 90 days to three years, until Oct. 15, 2023, if they can convince regulators that they need more time to properly dispose of the waste.

Moreover, if a company can demonstrate that it is shutting down a coal boiler, it can petition to keep its storage ponds open for as long as eight years, depending on their size. Slurry ponds smaller than 40 acres could get approval to stay in place until Oct. 15, 2023, officials said, while larger ones could remain open until Oct. 15, 2028.

Environmentalists have sharply criticized the proposals, arguing these containment sites pose serious risks to the public at a time when more frequent and intense flooding, fueled in part by climate change, could destabilize them and contaminate drinking water supplies that serve millions of people. The rules will be subject to public comment for 60 days.

The question of how to handle coal waste, which is stored in roughly 450 sites across the country, has vexed regulators for decades. The Obama administration negotiated for years with environmental groups, electric utilities and other affected industries about how to address the waste, which can poison wildlife and poses health risks to people living near storage sites.

Lisa Evans, an attorney specializing in hazardous waste law for the environmental group Earthjustice, said allowing the electric industry to extend the life of coal ash pits represents a particular threat to low-income and minority-group Americans, who often live near such installations.

It is also likely to add to ordinary consumers' costs. Last year, for example, a member of the Virginia State Corporation Commission estimated it could cost ratepayers as much as $3.30 a month over 20 years -- between $2.4 billion and $5.6 billion -- to clean up Virginia-based Dominion Energy's 11 coal ash ponds and six coal ash landfills in the state.

The EPA's proposals will retain several of the monitoring and public disclosure standards put in place in 2015, officials said, requiring companies to monitor nearby groundwater, publicly report the data and address any leaks that pollute area waterways. The "vast majority" of slurry ponds "are on the road to closure" under the new rule, an EPA official said.

The EPA today will also revise requirements for how power plants discharge wastewater, which contain some of the same kind of contaminants. Under the Obama administration, EPA staff had concluded it was feasible to prohibit any releases of such toxic materials by having the units continually recycle their water. The agency has now concluded this is far more costly than originally anticipated, and technological advances have made it cheaper to filter and capture the waste through a membrane system, officials said.
