Dakota Access Pipeline Environmental Assessment

Posted: 12/9/2015

Expiration date: 1/8/2016


Summary: Dakota Access, LLC proposes to construct and operate the Dakota Access Pipeline Project which would connect the Bakken and Three Forks crude oil production areas in North Dakota to existing infrastructure in Illinois. In North Dakota, the project crosses federal flowage easements at the Missouri River upstream of Lake Sakakawea in Williams County and federally-owned lands at Lake Oahe in Morton and Emmons counties. The pipeline is 24 inches in diameter where it crosses approximately 2.83 miles of the U.S. Army Corps of Engineers’ flowage easements at the Missouri River and is 30 inches in diameter where it crosses approximately 0.21 miles of federal lands at Lake Oahe.  The Omaha District is seeking public comments on the environmental assessment for these two project areas.
