The Financial Post reports in its Monday edition that in a string of towns across Kansas, Iowa and South Dakota, local officials are scrutinizing pipeline extensions. An Associated Press item inside the Post says that while TransCanada's Keystone XL project awaits a final decision, lesser-known developments that quietly added more than 11,600 miles of pipeline to the nation's domestic oil network, dwarfing Keystone. Over all, the network has increased by almost a quarter in the last decade. In Minnesota, local opponents succeeded last year in getting state regulators to consider rerouting a 616-mile pipeline proposed by Enbridge around pristine lakes and forests, delaying it for at least a year. More typical, though, was an Enbridge project to double the capacity of a 285-mile stretch of pipeline in Michigan. Groups like the Michigan Coalition Against Tar Sands fought the proposal, but the Michigan Public Service Commission ruled the project acceptable, and the expansion went ahead. "I'm telling people I don't think it's going to stop," said Paul Stolen, a retired state biologist who has been working with groups opposing the Enbridge project in Minnesota. "I think it's going to escalate and get bigger."
