>"On May 29, 2020, the largest fuel storage tank at Norilsk Heat and Power Plant No. 3 (HPP-3) burst at the bottom and spewed 6.5 million gallons of diesel fuel into the Daldykan River. From there it seeped into the Ambarnaya River, Lake Pyasino, the Pyasina River, and finally into the Kara Sea. It was the largest oil spill in Arctic history."
