Tough new EPA rules could close most coal plants by 2039

Coal-fired power plants would be forced to capture smokestack emissions or shut down under a rule issued Thursday by the Environmental Protection Agency.

New limits on greenhouse gas emissions from fossil fuel-fired electric plants are the Biden administration’s most ambitious effort yet to roll back planet-warming pollution from the power sector, the nation’s second-largest contributor to climate change. The rules are a key part of President Joe Biden’s pledge to eliminate carbon pollution from the electricity sector by 2035 and economy-wide by 2050.

The rule was among four separate measures targeting coal and natural gas plants that the EPA said would provide “regulatory certainty” to the power industry and encourage them to make investments to transition “to a clean energy economy.” They also include requirements to reduce toxic wastewater pollutants from coal-fired plants and to safely manage so-called coal ash in unlined storage ponds.

The plan is likely to be challenged by industry groups and Republican-leaning states. They have repeatedly accused the Democratic administration of overreach on environmental regulations and have warned of a looming reliability crisis for the electric grid. The rules issued Thursday are among at least a half-dozen EPA rules limiting power plant emissions and wastewater pollution.

Environmental groups hailed EPA’s latest action as urgently needed to protect against the devastating harms of climate change.

The power plant rule marks the first time the federal government has restricted carbon dioxide emissions from existing coal-fired power plants. The rule also would force future electric plants fueled by coal or gas to control up to 90% of their carbon pollution. The new standards will avoid 1.38 billion metric tons of carbon pollution through 2047, equivalent to the annual emissions of 328 million gas cars, the EPA said, and will provide hundreds of billions of dollars in climate and health benefits, measured in fewer premature deaths, asthma cases and lost work or school days.

Coal plants that plan to stay open beyond 2039 would have to cut or capture 90% of their carbon dioxide emissions by 2032, the EPA said. Plants that expect to retire by 2039 would face a less stringent standard but still would have to capture some emissions. Coal plants that are set to retire by 2032 would not be subject to the new rules.

Rich Nolan, president and CEO of the National Mining Association, said that through the latest rules, “the EPA is systematically dismantling the reliability of the U.S. electric grid.’'

He accused Biden, Regan and other officials of “ignoring our energy reality and forcing the closure of well-operating coal plants that repeatedly come to the rescue during times of peak demand. The repercussions of this reckless plan will be felt across the country by all Americans.”
