Plains & Eastern EIS

Project Update

During the public comment period on the Draft Environmental Impact Statement (EIS), the Department of Energy (DOE) received numerous comments requesting re-routing of the high voltage direct current (HVDC) Applicant Proposed Route or HVDC alternative routes. For each request, DOE reviewed the information supplied with the comment and coordinated with the applicant (Clean Line) to determine the feasibility of developing a route variation to avoid areas where new information indicated a potential conflict that could be avoided (e.g., previously unknown residences or structures, or environmentally or culturally sensitive areas). 

In some instances, variations were either not feasible or the variations were potentially feasible, but provided no added benefit or reduction in potential environmental impacts. In these instances, no variation was adopted. In several instances, based on the new information, a route variation that could avoid potential conflicts and lessen the potential environmental impact of the Applicant Proposed Route was developed. In these instances, route variations were proposed. The route variations that DOE is carrying forward into the Final EIS are available here

The Arkansas Converter Station Alternative and Tennessee Converter Station Siting Areas have been reduced in size as a result of engineering design work performed by the Applicant. These modifications, which DOE has reviewed and is carrying forward into the Final EIS, are available here.  

The Final EIS will provide a detailed description of each route variation and reductions in size of the Arkansas Converter Station Alternative and Tennessee Converter Station Siting Areas and discuss the potential environmental impacts associated with each.

Brief Project Overview

The Applicant Proposed Project would include an overhead ± 600 kilovolt high voltage direct current (HVDC) electric transmission system and associated facilities with the capacity to deliver approximately 3,500 megawatts primarily from renewable energy generation facilities in the Oklahoma and Texas Panhandle regions to load-serving entities in the Mid-South and southeastern United States via an interconnection with Tennessee Valley Authority in Tennessee. Major facilities associated with the Applicant Proposed Project consist of converter stations in Oklahoma and Tennessee, an approximate 720-mile HVDC transmission line, an alternating current (AC) collection system, and access roads.

Pursuant to NEPA, DOE has identified and analyzed potential environmental impacts for several alternatives in addition to the Applicant Proposed Project, including alternative routes for the HVDC transmission line and adding a converter station in Arkansas (to deliver power to the Arkansas electrical grid).

For more information, please see the Project Description webpage or Chapter 2 of the Draft EIS.

ended on April 20, 2015. Comments received after this date will be considered to the extent practicable. The U.S. Department of Energy (DOE) hosted 15 public hearings in January and February 2015 and held a 120-day comment period to receive comments on the Draft EIS.

DOE will now consider the comments received and prepare a Final EIS, which will include a Comment Response Document. The availability of the Final EIS will be announced in the Federal Register by the U.S. Environmental Protection Agency, and the Final EIS will be posted on this website and the DOE NEPA Website.

Announcements

During the public comment period on the Draft Environmental Impact Statement (EIS), the Department of Energy (DOE) received numerous comments requesting re-routing of the high voltage direct current (HVDC) Applicant Proposed Route or HVDC alternative routes. As a result DOE developed route variations. Reductions in size of the Arkansas Converter Station Alternative and Tennessee Converter Station Siting Areas have occurred as a result of engineering design work performed by the Applicant.

The comment period for the Draft Environmental Impact Statement (EIS) for the Plains & Eastern Clean Line Transmission Project (DOE/EIS–0486; Draft EIS) ended on April 20, 2015. Comments received after this date will be considered to the extent practicable.
