In March 2006, corrosion of a BP Exploration Alaska (BPXA) oil transit pipeline in Prudhoe Bay transporting oil to the Trans-Alaska Pipeline led to a five-day leak and the largest oil spill on Alaska's North Slope.[112] According to the Alaska Department of Environmental Conservation (ADEC), a total of 212,252 US gallons (5,053.6 bbl; 803.46 m3) of oil was spilled, covering 2 acres (0.81 ha) of the North Slope.[113] BP admitted that cost-cutting measures had resulted in a lapse in monitoring and maintenance of the pipeline and the consequent leak.
