MAP's Assessment and Listing Process is driven by Vermont's State Water Quality Standards. In 2017, DEC completed a review and update of the Vermont Water Quality Standards. A triennial review of state water quality standards is required by the federal Clean Water Act. See Triennial Review below for more information.
