"The Tennessee Valley Authority has long argued it shouldn't be required to limit the toxic metals that its coal-fired power plant dumps into the Cumberland River.
The Cumberland Fossil Plant's unusually large wastewater discharges, the federally owned utility maintained, merits a Clean Water Act exemption.
Without one, TVA said, the plant would be stuck — unfairly — with hefty compliance costs.
That argument failed to sway the Obama-led EPA, but it scored with Trump administration regulators who wrote an exemption for "high flows" into regulations proposed this month for water used to clean coal plants' air filters."
