Superior Terminal Mainline Optimization Project

Press Operations — Wed, 11 Mar 2026 15:43:00 GMT

The purpose of this notice is to advise the public that the following request associated with Enbridge Energy’s Superior Terminal Mainline Optimization Project has been submitted for a Department of the Army (DA) permit under the provisions of Section 404 of the Clean Water Act. In Executive Order (EO) 14156 the President declared a national emergency under the National Emergencies Act (50 U.S.C. 1621) based upon the finding that the United States’ insufficient energy production, transportation, refining, and generation constitutes an unusual and extraordinary threat to our Nation’s economy, national security, and foreign policy. The U.S. Army Corps of Engineers (Corps), St. Paul District has found that this permit request meets the terms of EO 14156 and is therefore subject to special emergency permitting procedures to address an energy supply situation which would result in an unacceptable hazard to life, a significant loss of property, or an immediate, unforeseen, and significant economic hardship if corrective action requiring a permit is not undertaken within a time period less than the normal time needed to process the application under standard procedures. The St. Paul District will implement the special processing procedures approved by Mississippi Valley Division in accordance with 33 CFR § 325.2(e)(4). The applicant proposes to discharge fill material in waters of the United States associated with construction activities for the Superior Terminal Mainline Optimization project. The applicant proposes to undertake this project at its Superior Terminal as part of a broader initiative to optimize transportation of crude oil to support the delivery of energy in North America. The project consists of installing water‑based cooling towers and associated equipment to support temperature maintenance of crude oil received from Line 67 and Line 93 within preferred storage tank operating ranges, thereby limiting emissions. The cooling towers will operate as an open loop, non‑contact cooling water system. No direct discharge to surface waters or wetlands is proposed.
