              FILE - In this photo taken by a drone, cleanup continues in the area where the ruptured Keystone pipeline dumped oil into a creek in Washington County, Kan., on Dec. 9, 2022. A faulty weld at a bend in an oil pipeline contributed to a spill that dumped nearly 13,000 bathtubs' worth of crude oil into a northeastern Kansas creek, the pipeline's operator said Thursday, Feb. 9, 2023, estimating the cost of cleaning it up at $480 million.
