LITTLE ROCK — Entergy Arkansas said Friday it is proposing to shut down Arkansas’ largest coal-fired power plant in 13 years.

LITTLE ROCK — Entergy Arkansas said Friday it is proposing to shut down Arkansas’ largest coal-fired power plant in 13 years.


In comments filed with the U.S. Environmental Protection Agency, the utility said it is proposing to cease operations at the White Bluff plant in Redfield. One of the units at the plant would shut down in 2027 and the second would shut down in 2028 under the proposal.


The company said it is "prepared to take an enforceable commitment to that effect."


Entergy filed the comments in response to the EPA’s proposed Regional Haze Rule plan, which seeks to improve visibility at national parks and wildlife areas by reducing power plant emissions.


The EPA has proposed that Entergy install controls for sulfur dioxide emissions at the White Bluff plant, as well as at Entergy’s Lake Catherine plant in Malvern, which runs on natural gas and oil.


In its comments Friday, Entergy said the EPA underestimated the cost to install the controls at the White Bluff plant and asked it to revise its proposed compliance plan to take into account the planned shutdown of the plant.


Glen Hooks, director of the Arkansas chapter of the Sierra Club, called the proposal a potential "giant step forward" for the state environmentally.


"At the same time, Entergy is building big solar farm as well that’s hopefully going to open in the next year," he said. "So our state’s largest utility is shutting down, or wants to shut down, our biggest coal plant and build solar at the same time. It’s a huge deal."


The Sierra Club will push for the shutdown to happen sooner than Entergy has proposed, he said.


A spokeswoman for Entergy did not immediately return a call Friday afternoon seeking comment.
