Air Quality

Motor vehicles, while an essential mode of transportation in a rural state like Vermont, are a major source of air pollutants that are associated with a variety of public health and environmental threats. A vehicle that possesses malfunctioning emission control systems can emit 50% more pollution than when it was originally manufactured.

This SIP revision is to protect and improve visibility levels in Federal Class I Areas in Vermont as well as in other states affected by air contaminant emissions originating in Vermont.  The only Class I Area in Vermont is the Lye Brook Wilderness Area within the Green Mountain National Forest.  This SIP revision establishes the progress goal and long term strategy for the second ten-year regional haze planning period (2018 – 2028) to achieve the goal of reaching natural background visibility levels by 2064.
