Northeast Energy Direct Project; Docket No. CP16-21-000 Supplemental Filing -- Tennessee’s Response to (1) Scoping Comments (October 2 through 16, 2015), and (2) the Commission’s Comments on Draft Environmental Report Dear Ms. Bose: On November 20, 2015, Tennessee Gas Pipeline Company, L.L.C. (“Tennessee”) filed with the Federal Energy Regulatory Commission an application for a certificate of public convenience and necessity (“Application”) for the proposed Northeast Energy Direct Project (“Project”) in the above-referenced docket. On December 7, 2015, the Commission issued a Notice of Application for the Project. Tennessee’s Response to Scoping Comments In the Notice of Intent to Prepare an Environmental Impact Statement for the Planned Northeast Energy Direct Project, Request for Comments on Environmental Issues, and Notice of Public Scoping Meetings, issued on June 30, 2015 in Docket No. PF14-22-000, the Commission established a scoping period through August 31, 2015 for the Project. The scoping period for the Project was extended until October 16, 2015 by the Commission in the Notice of Public Scoping Meeting for the Northeast Energy Direct Project, and Extension of Scoping Period, issued September 3, 2015 in Docket No. PF14-22-000. A matrix that included Tennessee’s responses to scoping comments was provided as Attachment A to the transmittal letter for the Application. In the transmittal letter, Tennessee noted that the matrix included responses to scoping comments filed with the Commission between June 30, 2015 and October 1, 2015, and that it would file responses to scoping comments filed between October 2, 2015 and October 16, 2015 (the conclusion of the scoping period) with the Commission no later than December 21, 2015. Included as Attachment A to this filing are Tennessee’s responses to scoping comments filed with the Commission between October 2, 2015 and October 16, 2015. Since many of the scoping comments reflect similar issues or themes, Tennessee has provided a combined response Federal Energy Regulatory Commission December 21, 2015 Page 2 to such comments, rather than providing a specific unique response to every scoping comment. For scoping comments that present unique issues, a specific response is provided. Tennessee’s Response to the Commission’s Comments on Draft Tennessee also included with the Application a matrix (filed as Attachment B to the transmittal letter) that addressed comments from Commission Staff, dated (1) February 27, 2015 (draft Resource Reports 1 and 10, filed November 5, 2014 and updated on December 8, 2014); (2) May 15, 2015 (first draft Environmental Report, filed on March 13, 2015) and (3) October 8, 2015 (second draft Environmental Report, filed on July 24, 2015). Tennessee noted in the matrix that certain responses to the Commission Staff comments would be submitted in a supplemental filing to be filed no later than December 21, 2015. Tennessee now submits a matrix responding to the remaining Commission Staff comments as Attachment B to this filing. The matrix includes either the response to the Commission Staff comment or a reference to the location in the Application or Environmental Report where the response to the Commission Staff comment may be found. In accordance with the Commission’s filing requirements, Tennessee is submitting this Application with the Commission’s Secretary through the eFiling system. Tennessee is also providing complete copies of this Application to the Office of Energy Projects.
