ANCHORAGE, Alaska - State officials have increased the size of an oil leak on the North Slope.
Officials on Wednesday said an oily mist was sprayed over 33 acres of snow-covered tundra and 2 acres of gravel pad because of a pipeline failure. Initial reports said 27 acres of tundra were affected.
Authorities say the release of natural gas and water containing crude oil was found during routine inspections Monday. The spray was active for about two hours before the line was isolated and depressurized.
Crews are working in two shifts to clean the area of oil
The spill happened at the BP Exploration (Alaska) west operating area in Prudhoe Bay, at H Pad Well 8.
