After the shutdown, BP pledged to replace 26 kilometres (16 mi) of its Alaskan oil transit pipelines[124][125] and the company completed work on the 16 miles (26 km) of new pipeline by the end of 2008.[126] In November 2007, BP Exploration, Alaska pleaded guilty to negligent discharge of oil, a misdemeanor under the federal Clean Water Act and was fined US$20 million.[127] There was no charge brought for the smaller spill in August 2006 due to BP's quick response and clean-up.[114] On 16 October 2007, ADEC officials reported a "toxic spill" from a BP pipeline in Prudhoe Bay comprising 2,000 US gallons (7,600 l; 1,700 imp gal) of primarily methanol (methyl alcohol) mixed with crude oil and water, which spilled onto a gravel pad and frozen tundra pond.[128]
