Dalton Expansion Project Final Phase I report Addendum 3: Bartow, Carroll, Coweta, Douglas, Gordon, Murray, Paulding, and Whitfield Counties, Georgia

This report is an addendum to the Dalton Expansion Project report detailing results of the additional Phase I survey work carried out from November 2015 through July 2016. The additional work was conducted as the result of numerous planned reroutes and gaining access to previously inaccessible portions of the corridor and workspace. The original Phase I survey document was submitted to the Federal Energy Regulatory Commission (FERC) and to the Georgia Historic Preservation Division (HPD) in May 2015. The purpose of the investigation was to locate, identify, and evaluate any archaeological properties in the Area of Potential Effect (APE) of the proposed undertaking. An APE is defined as "the geographic area or areas within which an undertaking mi=3y directly or indirectly cause changes in the character or use of historic properties, if any such properties exist" (36 CFR Part 800.16[d]).

During the Phase I investigations, survey was conducted within parcels to which access was granted before the time of survey. In this document parcels are discussed by their Project specific parcel number, which is separate from their tax or other identification numbers. During the current survey, an approximate distance of 32.24 miles was surveyed. These were either areas to which access had not been previously granted, or they were surveyed as the result of the most recent reroutes. At the time of survey, 29 parcels within the survey corridor were inaccessible due to land ownership and other issues, accounting for a total of 6.3 miles of workspace and wider corridor. A total of 19 archaeological occurrences were investigated, including 15 archaeological sites and four Isolated Finds (IFs) located within the project corridor (see Table 1 and Table 2). All four IFs are considered ineligible for the NRHP, due to their extremely low potential to produce additional archaeological data.

Of the 15 archaeological sites, four were previously recorded and were revisited as part of this survey. Site 9BR1132 was recommended as eligible for the NRHP after Phase II testing and was revisited due to an avoidance plan that shifted the route to the east of the site. Additional shovel tests expanded the survey boundary, but the portion of the site within the workspace was determined to lack data potential. The current reroute avoids the area of the site that retains integrity and the potential for additional significant data recovery. As a result, no further work is recommended in conjunction with this Project and a determination of no adverse effect is recommended.
