The Minnesota Department of Natural Resources has opened a public comment period for pending Enbridge’s Line 3 oil pipeline permits.

The DNR will take comments for 60 days, from March 18 through 4:30 p.m. on May 17.

The agency is weighing 10 different permits for the proposed pipeline.

Comments can be submitted online at mndnr.gov/line3 or mailed to the Department of Natural Resources, Attn: Line 3 Pipeline Replacement Applications, 500 Lafayette Road, St. Paul, MN 55155.

While the Minnesota Public Utilities Commission has fully approved a certificate of need and route permit for Line 3, numerous other permits are still being weighed by other organizations.

Permitting will likely conclude in November, the state said earlier this month. Enbridge now hopes to construct the pipeline in 2020.

The controversial pipeline is set to replace the 50-year-old Line 3 and carry 760,000 barrels of oil per day from Alberta to the Enbridge terminal in Superior.
