New York Attorney General Letitia James announced Wednesday the state is joining a lawsuit being filed against the U.S. Environmental Protection Agency, alleging it failed to address air pollution problems.

James and attorneys general in multiple states allege the EPA is in violation of the Clean Air Act for not taking action on the pollution coming from other states in the region.

The lawsuit points to seven upwind states, including Illinois, Michigan, and Virginia, are causing harmful air pollutants to contaminate New York's air.

It also says that this is the reason the state has not been able to meet federal Clean Air Act standards.

"The transport of air pollution from upwind states continues to threaten the health and safety of New Yorkers," James said in a statement. "The federal government’s refusal to enforce the Good Neighbor Provision of the Clean Air Act allows the smog caused by upwind air pollution to go unaddressed."

The federal Court of Appeals for the D.C. Circuit ruled in October last year that the EPA needed to find a fix to keep air pollutants from traveling from state to state. They also ruled that the EPA develop the "Good Neighbor Provision."

New York officials, however, believe the EPA is yet to fully take action to address the issue.

This lawsuit also includes New Jersey, Connecticut, Delaware and Massachusetts as well as the city of New York.
