"Six Northeastern U.S. states and New York City have sued the Trump administration over its refusal to toughen smog restrictions in industrial states that blow pollution across their borders, officials said on Thursday.
The lawsuit is the latest of several filed by Democratic-led or -leaning states challenging U.S. President Donald Trump’s environmental policies, many of which are aimed at reducing the regulatory burden on business.
At issue is an update to the “Good Neighbor Provision” of the Clean Air Act, a requirement that the U.S. Environmental Protection Agency (EPA) step in when smog emissions from states prevent their downwind neighbors from meeting federal smog health standards. The provision was introduced by the administration of former President Barack Obama. "
