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.
