PHASE I CULTURAL RESOURCE SURVEY OF THE GEORGIA PORTION OF THE SABAL TRAIL PROJECT, STEWART, WEBSTER, TERRELL, LEE, DOUGHERTY, MITCHELL, COLQUITT, BROOKS, AND LOWNDES COUNTIES, GEORGIA DRAFT REPORT – ADDENDUM 5

Saba! Trail Transmission, LLC (Saba! Trail), a joint venture among affiliates of Spectra Energy Partners, LP, NextEra Energy, Inc., and Duke Energy Corporation, has been issued a Certificate of Public Convenience and Necessity by the Federal Energy Regulatory Commission (FERC) pursuant to Section 7( c) of the Natural Gas Act authorizing the construction and operation of the Sabal Trail Project (Project) (FERC Docket No. CP-15-17-000; DA Permit No. SAS-2013-00942; HPD No. HP-1 3 1022-004). The Project involves construction of ca. 480.7 miles of new 36-inch natural gas pipeline (the mainline route) from a Transcontinental Gas Pipeline Company, LLC (Transco) pipeline in Tallapoosa County, Alabama to a new interconnection hub (the Central Florida Hub) in Osceola County, Florida. The Project will also include construction of associated compressor stations, meter and regulating (M&R) stations, and mainline valves (ML Vs), and use of additional temporary work spaces (ATWSs), access roads, and contractor yards. In addition, the Project will include construction of approximately 13.1 miles of new 36-inch diameter pipeline (the Hunters Creek Line) and 21.5 miles of new 24-inch pipeline (the Citrus County Line) in Florida.

Approximately 161.7 miles of the Saba! Trail mainline route are located in Georgia, where the route traverses Stewart, Webster, Terrell, Lee, Dougherty, Mitchell, Colquitt, Brooks, and Lowndes counties. Associated above-ground facilities in Georgia include the Albany Compressor Station as well as eight MLVs and a Launcher/Receiver site, all of which will be located along the route or within the Albany Compressor Station site. In addition, the Project will also involve the use of over 100 access roads and contractor yards in Georgia, as well as a number of A TWSs. The Project Area of Potential Effects (APE) for archaeological resources in Georgia was defined as a 300-ft-wide (ca. 91.44-m-wide) environmental study corridor containing the mainline route, and also includes a 50-ft-wide (ca. 15.24-m-wide) corridor along proposed access roads as well as the footprints of compressor station and M&R station sites and of other support facilities.

A revised draft report (Kosalko et al. 20 15) documenting the initial cultural resources surveys of the Georgia portion of the Project, including the mainline route as well as associated facilities, was submitted to the Historic Preservation Division (HPD) of the (Georgia) Department of Natural Resources (DNR) in May 2015. That report presented the results of surveys conducted by TRC Environmental Corporation (TRC) on behalf of Saba! Trail from September 2013 through July 2014, as well as supplemental surveys requested by the HPD in the same survey areas, which were conducted in February 2015. Addendum reports (Kosalko and Burr 2015a, 20 15b, 20 16; Kosalko and Webb 20 15) covering additional surveys have also been submitted to and reviewed by HPD, and revised drafts of those reports have been submitted. Associated surveys conducted for the Alabama and Florida portions of the Project were reported separately, as were the Phase II archaeological investigations.

This addendum report (Addendum 5) documents previously unreported surveys conducted along the mainline route and at access roads. The archaeological surveys took place in Webster, Colquitt, and Brooks counties, and covered approximately 0.19 miles (0.31 km) of the pipeline route and three access roads. These surveys did not result in identification of any additional archaeological or historic architectural resources, but provided additional information concerning previously identified archaeological site 9B050, which is now recommended ineligible for the National Register of Historic Places.
