Environmentalists cry foul as 'Alberta Clipper' tries to pile on more sail.

摘要

Canadian pipeline company Enbridge has announced plans to increase die capacity of its Alberta Clipper Pipeline diat runs IK mi (1.6 km) from Hardisty, Alberta (Canada) to Superior, Wisconsin (US.) The $159MM project involves adding pumping stations to increase the pressure on the 36-in (0.91-m) pipe—pressure that the company says the pipe was designed to handle, as Enbridge had the expansion in mind when the line was originally installed in 2010—to increase capacity by 40% to 800K b/d.
