WASHINGTON — The Trump administration will formally propose repealing former President Barack Obama’s sweeping plan for curbing greenhouse gas emissions from power plants by arguing it went beyond the bounds of federal law, according to documents obtained by Bloomberg News.
The Environmental Protection Agency will not prescribe an immediate replacement to the plan, and instead will soon ask the public to comment on how best to curb carbon-dioxide emissions from coal and natural gas power plants, according to a draft of the proposed rule and other government documents.
The proposal, set to be unveiled in coming days, is a first step to delivering on President Donald Trump’s promise to rip up the Clean Power Plan, which served as the cornerstone of Obama’s climate change agenda. Trump moved to pull the U.S. out of the global Paris climate accord, and he has dismissed global warming as a hoax.
Obama’s initiative was designed to cut U.S. carbon dioxide emissions 32 percent below 2005 levels by 2030. Because of legal challenges, it never actually took effect: The U.S. Supreme Court put it on hold in February 2016.
The Obama-era rule dictated specific carbon-cutting targets for states based on a complex formula tied to their 2012 power plant emissions — and then gave them broad latitude to decide how to achieve those reductions, including such things as promoting energy conservation.
This was a unique and controversial approach. The EPA’s other air pollution regulations — promulgated under the same provision of federal law — are based on a system that “can be applied to or at a single source,” the draft proposal says.
The Trump administration is arguing that such forced “generation shifting” is inconsistent with the EPA’s authority under the Clean Air Act.
“The Clean Power Plan departed from this practice by instead setting carbon dioxide emission guidelines for existing power plants that can only realistically be effected by measures that cannot be employed to, for, or at a particular source,” the document says.
In his previous role as attorney general of Oklahoma, EPA Administrator Scott Pruitt joined leaders of roughly two dozen other states in arguing the Clean Power Plan violated federal law by imposing broad energy market changes instead of individual requirements on specific power plants.
The administration’s rationale suggests any replacement will have to focus on what can be done at individual power plants, which would lead to more modest requirements on utilities.
The administration will take two separate steps: repealing and then, possibly, replacing.
First, in coming days, it will issue its proposed rule to rescind the earlier regulation. Later, it will issue a formal notice asking the public to comment on whether the EPA can or should develop a replacement rule — and, if so, what options are legal, feasible and appropriate for curbing emissions of power plants. That could mean requiring modest efficiency upgrades or the installation of carbon-capture technology at the sites.
The EPA has not determined whether it will promulgate a new rule to regulate greenhouse gas emissions, according to the documents.
The Trump administration is set to argue that repealing the Clean Power Plan could spare an estimated $33 billion in compliance costs in 2030. Details of that economic analysis were not immediately available.
The Environmental Protection Agency declined to comment on the authenticity of the documents.
“The Obama administration pushed the bounds of their authority so far that the Supreme Court issued a stay — the first in history — to prevent the so-called ‘Clean Power Plan’ from taking effect,” EPA spokeswoman Liz Bowman said by email. “Any replacement rule that the Trump administration proposes will be done carefully and properly within the confines of the law.”
