An environmental group sued the Trump administration Friday to obtain records related to EPA’s efforts to allow coal plants and large industrial facilities to seek exemptions from clean air standards.

The Environmental Defense Fund filed suit in the U.S. District Court for the District of Columbia after it said EPA failed to produce the documents requested under the Freedom of Information Act.

“The Trump EPA has issued a sweeping invitation to hundreds of large industrial facilities to apply for a pass to pollute, and EPA has not publicly released the requests they received or their responses,” said EDF senior attorney Erin Murphy.

Murphy said the compliance exemptions would allow facilities “to emit more pollutants that cause cancer, heart and lung diseases, and brain damage in babies. People have a right to know if their government plans to allow more dangerous, toxic chemicals into the air they breathe.”
