The three states on the Delmarva Peninsula have joined 19 others in a suit against the easing of restrictions on coal-fired power plants.
The U.S. Environmental Protection Agency has put in a new rules that allows states more latitude in upgrading such facilities.
The suit argues that does not meaningfully replace the greenhouse gas emissions from the power plants as required under the Clean Air Act.
WBOC reports that Maryland Attorney General Brian Frosh chastised the administration saying that EPA is prioritizing the coal industry over clean, renewable energy.
He warned that the new regulation would do long-lasting damage to public health and accelerate climate change.
