EPA Chief: States Cannot Block Ohio Train Derailment Waste.

The Environmental Protection Agency (EPA) has stated that it is "impermissible" for states to block contaminated waste from a toxic train derailment in Ohio. Some states have sought to block shipments of the type of waste that certified facilities routinely handle every day. The EPA has said that blocking the shipments was likely in violation of federal law, as well as the Commerce Clause of the U.S. Constitution, which limits the power of states to stop the movement of hazardous waste. The EPA expects the rail operator to pursue legal action if it is unable to ship the waste to certified disposal facilities.
