June 22, 2023



In accordance with Section 401 of the federal Clean Water Act (33 U.S.C. Par. 1251 et seq.), certification that Title 117 – Nebraska Surface Water Quality Standards (Nebraska Administrative Code) will not be violated has been applied for to the Nebraska Department of Environment and Energy (NDEE) by the persons listed below for discharges requiring Federal permits or licenses.

Tallgrass Energy Partners, LP has applied for a Section 404 permit from the U.S. Army Corps of Engineers (USACE) to conduct activities in Waters of the United States. The proposed project requires state Water Quality Certification in accordance with Clean Water Act (CWA) Section 401(a)(1), which states that:

(1) Any applicant for a Federal license or permit to conduct any activity including, but not limited to, the construction or operation of facilities, which may result in any discharge into the navigable waters, shall provide the licensing or permitting agency a certification from the State in which the discharge originates or will originate, or, if appropriate, from the interstate water pollution control agency having jurisdiction over the navigable waters at the point where the discharge originates or will originate, that any such discharge will comply with the applicable provisions of sections 301, 302, 303, 306, and 307 of this title.

Tallgrass Energy Partners, L.P. (Tallgrass) is seeking a nationwide permit to build two pipelines in central Nebraska. Tallgrass owns Trailblazer Pipeline Company, LLC (TPC) and its subsidiary owns 75% of Rockies Express Pipeline, LLC (REX). These two companies, TPC and REX, are applicants for the Trailblazer Conversion Project. This project will require the construction of two new natural gas lateral pipeline segments totaling approximately 41 miles. The REX Lateral to TPC East pipeline will be located in Jefferson County, Nebraska between Steele City and Swanton. The REX Lateral to TPC Adams pipeline will be located in Webster and Adams Counties between Campbell and Hastings. Additionally, there will be construction by REX of 5 new interconnect booster compressor stations at existing Trailblazer Pipeline facilities, installation of station piping at 4 existing Trailblazer Pipeline meter stations, expansion of 1 existing meter station between REX Pipeline and Trailblazer Pipeline, and construction of 2 new REX meter stations.

The applicant has stated that the potential impacts to aquatic resources may occur from the construction of the 2 pipeline segments due to open trench excavation within aquatic resources and horizontal boring under 1 aquatic resource. Temporary impacts to 20 separate wetland features (1.343 acres) and 26 riverine features (0.384 acres) are anticipated. No permanent impacts are anticipated.

In order to evaluate the impacts of these permits on the water resources of the State of Nebraska, NDEE encourages interested citizens to submit favorable or unfavorable written comments.
