Keystone would transport crude oil from the tar sands regions of the Canadian West, across parts of the U.S. Midwest and down to refineries on the Gulf Coast for potential export overseas. The House of Representatives on Friday passed a bill expediting construction of the pipeline, which has been delayed for years because of political opposition and concerns about its environmental impact. The Senate will consider a similar measure on Tuesday.
Some critics contend that the pipeline could cause gas prices to rise, especially in the Midwest.That's because the oil that would be transported is not intended for American consumers. Rather, the Canadian oil currently sent to refineries in Illinois, Ohio and elsewhere in the Midwest would end up being diverted to Keystone, chiefly for export to markets overseas.
