Operator of two Cook Inlet crude tankers asks the state to renew their spill plan
Fairwater Tankers Alaska has asked the state to renew the oil spill plan for two tankers that carry North Slope crude up Cook Inlet to Nikiski. The Alaska Department of Environmental Conservation opened public comment Tuesday.
Under state law, the tankers can't operate in state waters without an approved plan, and the plan has to be submitted for renewal every five years. It has to show the company has enough resources lined up to prevent a spill and to respond to what regulators call a "realistic maximum discharge." The current plan expires Aug. 2, 2027.
The tankers, the California and the Washington, load crude at the Valdez Marine Terminal, at the end of the trans-Alaska pipeline, and make about 12 runs a year across the Gulf of Alaska and up the inlet, according to the department's public notice. They're usually in state waters for at least 48 hours on the way from Valdez.
They unload at the Kenai Pipe Line Company dock, about 11 miles north of Kenai. Crude that arrives there is pumped into the Kenai refinery's storage tanks, according to a 2022 state permit notice. Marathon Petroleum, which runs the refinery, says it processes mainly Alaska crude into gasoline, distillates, asphalt and other products.

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.
