"The Environmental Protection Agency notified Missouri environmental regulators this month that the state’s plan for overseeing the disposal of toxic waste from coal-fired power plants is not strong enough to protect human health and the environment.
In a recent letter to the Missouri Department of Natural Resources, EPA officials noted several provisions in the state’s plan that are weaker than the 2015 federal coal ash rule. Some allow the Missouri Department of Natural Resources to waive requirements for utility companies to clean up groundwater contamination or even monitor groundwater for toxic chemicals if they can show that it doesn’t affect drinking-water supplies or harm the environment.
Environmentalists and utility companies have disagreed over whether the MDNR’s proposed coal ash regulations will be strong enough to address contamination that’s been detected near many coal ash ponds and landfills in Missouri. The number of comments EPA has made about the state’s plan is unusual, said Andy Knott, a representative for the Sierra Club’s Beyond Coal campaign."
