"Greens Challenge Trump’s Rollback Of Coal Ash Standards"

"Environmental groups are suing the Trump administration for rolling back parts of a major regulation governing how companies store coal ash.

The groups, led by Earthjustice, filed their lawsuit Monday against the Environmental Protection Agency (EPA) in the U.S. Court of Appeals for the District of Columbia Circuit.

The original 2015 rule from the Obama administration was the first national regulation regarding disposal of coal ash, a black sludge leftover from burning coal that contains concentrated levels of heavy metals like arsenic, cadmium and chromium. Coal ash storage ponds are often adjacent to waterways, since coal-fired power plants need cooling water."
