dec.alaska.gov ↗Alaska
The Alaska Department of Environmental Conservation, known as DEC, is the State of Alaska agency that regulates environmental quality across the state. It issues permits for air emissions, wastewater discharges and the filling of wetlands. It also oversees oil spill prevention and response, contaminated site cleanup and food safety inspections.
Much of its work runs through permits that open for public comment before they are issued or renewed. Recurring questions concern discharge permits for municipal sewage plants, seafood processors and cruise ships, air permits for North Slope oil fields and industrial sites, spill plans for fuel terminals and platforms, and PFAS contamination in drinking water. How long facilities operate under expired or violated permits, and how the department enforces them, also returns often.
DEC works alongside other state agencies such as the Department of Natural Resources and the Department of Fish and Game. Its decisions reach communities from Kodiak and Ketchikan to Fairbanks and the Mat-Su, wherever a plant discharges to water or a project fills wetlands.
