The plunging price for natural gas, as well as for solar and wind energy, have pushed utilities to move toward cleaner burning fuels, regardless of federal regulations.
Michelle Bloodworth, president of the American Coalition for Clean Coal Electricity, a trade group that represents coal producers, called the new rule a marked departure from the "gross overreach" of the Obama administration and said it should prevent a host of premature coal-plant retirements.
The EPA said it "empowers states, promotes energy independence, and facilitates economic growth and job creation".
One thing Trump's Affordable Clean Energy rule will do is likely to allow older coal plants to hang on a bit longer than they would've otherwise.
Trump has already vowed to pull the USA out of the Paris climate agreement as he pushes to revive the coal industry.
"Tuesday's move opens a public-comment period on the proposal before any final approval by the president".
"A coal plant that operates more efficiently may be called upon to run more hours, increasing the total amount of Carbon dioxide emitted overall", Lissa Lynch, an attorney for the Natural Resources Defense Council, said in a statement.
The U.S. Environmental Protection Agency (EPA) proposal would give states wide latitude for determining how to cut greenhouse gases from the power sector, a key contributor in the U.S.to climate change. Survey results showed that 72 percent of those responding to the survey said coal may become obsolete in the decades ahead.

Trump's efforts to save coal have included everything from moving to pull out of the Paris Agreement on climate change to using national security law to propose intervening in electricity markets to protect coal. Earlier in August, they announced plans to scale back fuel efficiency requirements for cars; past year, they pulled out of the Paris agreement on climate change.
A technical analysis released by the EPA suggests that the new plan would decrease carbon dioxide emissions by no more than 2% compared to doing nothing.
Environmental advocates and the architects of former President Barack Obama's ambitious plan derided the Trump administration's proposed replacement as political pandering and said it represented a US retreat from the global fight against climate change.
For states, acting EPA Administrator Andrew Wheeler said it eliminates federal oversight in a way that would leave room for environmental considerations while at the same time advancing Trump's goal of energy dominance.
Trump can deny these truths all he likes, but they aren't going away, and neither is the dire threat of climate change, which is why we need a strong policy like the Clean Power Plan.
By 2030, carbon dioxide levels would be 0.7 percent to 1.5 percent lower than they would have without any regulation in place, it said, a reduction of 12 million to 24 million metric tons. We speak with Mary Anne Hitt, director of the Sierra Club Beyond Coal Campaign.
The Obama administration used a new reading of the Clean Air Act to implement the new and expansive rules.
Obama's energy plan aimed to usher in the strictest anti-pollution measures in history on power plants, but was put on hold in 2016 by the US Supreme Court. "Environmental regulation in many cases is one of the leading causes of the decline in emissions that we observed over the past twenty years", said Reed Walker, an associate professor at UC Berkeley who co-authored a recent study that found regulation to be a key factor in reducing emissions in the manufacturing sector, even with increasing output.
Trump, who has scheduled a rally on Tuesday in coal-producing state West Virginia, has vowed to end what he termed "the war on coal" and boost domestic fossil fuels production.
