The meetings will deal with the scope of an upcoming environmental review. Sandpiper would carry North Dakota light crude to Enbridge's terminal in Superior, Wisconsin, while the Line 3 replacement would carry Canadian tar sands oil to Superior, sharing much of the same route as Sandpiper.
Regulators have prepared a draft laying out what the environmental review would cover and a tentative schedule. The Public Utilities Commission will use the review in deciding if the pipelines are needed and what route they should take.
The meetings run from April 15-May 11 in communities along the planned route, and May 9 in St. Paul.
