WASHINGTON (AP) — The Trump administration is considering rewriting another Obama-era rule controlling hazardous emissions from coal-fired power plants, this one on mercury and other pollutants.
Environmental Protection Agency spokeswoman Molly Block said Wednesday that the agency is still preparing its proposal for consideration by the White House’s Office of Management and Budget and that there are few details to release.
The EPA is looking at whether the 2012 rule on power plant emissions was necessary, among other issues, Block said.
The Obama administration rule set limits for emissions of mercury, arsenic and other toxic air pollutants from coal- and oil-fired power plants. The U.S. Energy Information Administration said last year that almost all the country’s coal-fired power plants were now in compliance with the 2012 rule.
