OMAHA, Neb . --
OMAHA, Neb. – The U.S. Army Corps of Engineers, Omaha District is seeking public comments as part of a draft environmental assessment for a proposal to perform maintenance activities to prevent scour on the existing Tesoro High Plains Pipeline Company, LLC, 12-inch Ramberg to Mandan pipeline system. This system runs underneath and on Federal lands including Lake Sakakawea in McKenzie and Williams counties in North Dakota.
The draft EA analyzes the environmental impacts of completing maintenance and stabilization activities to prevent damage to an existing crude oil pipeline which was constructed in the 1950s, and has been exposed to erosion from wave, wind and ice action.
The proposed project would utilize a combination of riprap and grout bags to provide the required depth of cover, 48-inches, and stabilization to approximately 1,375 linear feet of existing pipeline. The work would take place at the north and south shore of Lake Sakakawea in North Dakota.
The draft EA is available at: www.nwo.usace.army.mil/Missions/Civil-Works/Planning/Project-Reports/
Comments can be mailed to: U.S. Army Corps of Engineers, Omaha District; CENWO-PMA-C; ATTN: John Shelman; 1616 Capitol Avenue; Omaha, NE 68102-4901. Comments can also be emailed to: email@example.com. Comments must be postmarked or received no later than March 24, 2021.
This draft EA is consistent with the National Environmental Policy Act of 1969, as amended, the Council on Environmental Quality’s regulations for implementing NEPA (40 CFR 1500-1508), the Corps’ regulations for implementing NEPA (33 CFR 325 and Engineering Regulation 200-2-2) and other applicable environmental laws and regulations. The analysis was completed by a third party, which is allowed in accordance with CFR 1506.5(b).
