DENVER (AP) - Environmental groups opposed to Colorado’s proposed $1.2 billion expansion of Interstate 70 in northeast Denver have filed a federal lawsuit in an attempt to stop the project.

The Denver Post reports ( ) that other groups have joined the Sierra Club’s lawsuit challenging new Environmental Protection Agency Clean Air Act requirements that are being used to justify the expansion. The lawsuit was filed in the U.S. Court of Appeals for the District of Columbia Circuit.

The Colorado Department of Transportation says increased emissions from traffic on the expanded I-70 would not violate the new Clean Air Act requirements, though old standards would have disqualified the project from receiving federal funds. Under the new guideline, multiple high pollution days in a row would not be counted against the standard.

An EPA spokeswoman declined to comment.
