BP has started to clean up a half-acre area fouled by oil that leaked from a flow line that carries oil and water to a processing center on Alaska’s North Slope, according to AP:
The pipe, which is about 5 feet off the ground, was not in operation when the leak was discovered. The oil and water leaking from the pipe is congealing and freezing in a cone-shaped pile, [a BP spokesman] said.
The Alaska Department of Environmental Conservation estimates the spill area at about a quarter-acre. The estimate includes an area that was “misted” with oil.
