Additional Cultural Resources Investigation of the ETNG/SONAT Interconnect Project Catoosa County, Georgia

This document reports on a Phase I archaeological survey conducted for the revised project areas to the proposed ETNG/SONAT Interconnect Project (see attached alignment sheets and topographic maps). The revisions include a pipeline route realignment, an access road extension, and a minor access road realignment. The archaeological survey of the original part of the project has previously been documented in a report prepared by Garrow Bc Associates, Inc. (Garrow) entitled Cultural Resources Investigation of the ETNG/SONAT Interconnect Project, Hamilton County, Tennessee and Catoosa County, Georgia, dated December, 1994 by Joe D. Dunn. This report constitutes an addendum to the original report. The proposed realignment of approximately 0.85 miles is located in Catoosa County, Georgia between State Route 2 and Interstate 75 (Figure 1). It extends from survey milepost (BEEP.) 6.95 (centerline station 366~90) to Me end of the original pipeline alignment at the proposed SONAT interconnect (see alignment sheet 3). The proposed metering facility site location has shifted slightly to the east in conjunction with the realignment. An approximate 1,800-foot extension to the use of an existing access road identified in the original report is also proposed in association with the realigned right-of-way (labeled as Access Road A us Figure 1). A minor realignment of an access road at M.P 3.4 is also proposed (Figure 2). This access road will be realigned 25 50 feet to the south of the previous alignment (see alignment sheet 2). The archaeological survey for these sections was conducted between January 6 and 9, 1995 by personnel from Garrow's Atlanta, Georgia office. John Hutchings from KING provided field assistance. The field crew conducted a surface survey of the entire length of the proposed right-of-way, associated work spaces, Me meter station area, and the new access road locations. Shovel test pits were excavated at 3D meter intervals in all sections that were not too steep, too wet, or previously disturbed. All areas that were not shovel tested were documented and justified in the field notes. The survey identified three prehistoric archaeological sites (9CT46, 47, and 48) and one prehistoric isolated find One Site was located in Me proposed new pipeline right-of-way at Station 370~70, and the other two sites and the isolated find were found on Access Road ~ Sites 9CT46 and 9CT47 and the isolated find were found to be low density, disturbed lithic scatters and our conclusion is that they are not significant. Site 9CT48 may be potentially significant, but Access Road A was modified to completely avoid the site, so no further studies are needed at this time.
