Five major U.S. metro areas, including Denver, could be required to develop plans for reducing air pollution after the U.S. Environmental Protection Agency determined they have failed to meet air quality standards for ground-level ozone. The proposed EPA designations for metro Chicago, Dallas, Denver, New York City and Houston also could tighten permitting rules for certain projects in those areas as their air quality is reclassified from “serious” to “severe.” 

“[Owners] are not going to want to put a new source in an area that is in serious non-attainment.”

Under the federal Clean Air Act, states need to implement measures to curtail smog and protect public health when EPA reclassifies areas. Moreover, federal dollars can be withheld for transportation projects until an area is able to sufficiently reduce ground-level ozone to within National Ambient Air Quality Standards limits.

HNTB to Perform DIA Environmental Review Denver International Airport has hired HNTB Corp. to prepare an environmental assessment for the airport’s proposed seventh runway project. The runway will be the first to be built at the Denver airport since 2003.
