 Docket Nos. CP06-470-000, et al. 

TO THE PARTY ADDRESSED: 

The staff of the Federal Energy Regulatory Commission (FERC or Commission) in 

cooperation with the U.S. Army Corps of Engineers (COE); U.S. Coast Guard (Coast 

Guard); and the National Oceanic and Atmospheric Administration, National Marine 

Fisheries Service has prepared this final Environmental Impact Statement (EIS) for the 

Elba III Project. The project is proposed by Southern Natural Gas Company (Southern) 

and its subsidiaries Southern LNG Inc. (Southern LNG) and Elba Express Company, 

L.L.C. (EEC). The proposed facilities consist of an expansion of Southern LNG's 

existing onshore Elba Island Liquefied Natural Gas (LNG) Import Terminal on the 

Savannah River in Georgia and construction and operation of the Elba Express Pipeline - 

a natural gas pipeline with compression and other appurtenant facilities in various 

counties in Georgia and South Carolina. 

The final EIS was prepared to satisfy the requirements of the National Environmental 

Policy Act of 1969 (NEPA). Its purpose is to inform the Commission, the public, and 

other permitting agencies about the potential adverse and beneficial environmental 

impacts associated with the proposed project. It also recommends practical, reasonable, 

and appropriate mitigation measures which would avoid or reduce significant adverse 

impacts to the maximum extent practicable and, where feasible, to less than significant 

levels. 

In addition to the proposed action, the final EIS evaluates alternatives, including 

alternative energy sources, system alternatives, alternative sites for the LNG import 

terminal, alternative designs, pipeline alternatives, and alternatives to the Coast Guard 

Letter of Recommendation (LOR) action. The final EIS concludes that the Elba III 

Project could result in limited significant adverse environmental impact. However, if the 

project is constructed and operated in accordance with applicable laws and regulations, 

Southern LNG and EEC’s proposed mitigation, and the additional mitigation 

recommendations (see section 5), it would be an environmentally acceptable action. 

Proposed Facilities - Elba Terminal Expansion 

Southern LNG plans to construct and operate an expansion of its existing LNG import 

terminal on Elba Island near Savannah, in Chatham County, Georgia. The expansion 

would (a) more than double the terminal’s LNG storage capacity by adding 405,000 cubic 
Docket Nos. CP06-470-000, et al. - 2 -

meters (m3

) of new storage; (b) substantially increase the facility’s existing vaporization 

capacity; (c) upgrade the terminal’s send-out meter station capacity by an additional 900 

million cubic feet per day (MMcfd); and (d) modify the terminal’s LNG tanker berthing 

and unloading facilities to accommodate larger tankers and provide simultaneous 

unloading of two LNG tankers. Terminal expansion would entail an increase in the 

frequency (and potentially the size) of LNG vessels using the Savannah River transit 

route. All of the planned facilities would be located entirely within the existing 190-acre 

facility site on Elba Island. 

The LNG terminal expansion would be constructed in two phases, A and B. Phase A 

would be completed as early as January 2010 and would include the following facilities: 

a. one new 200,000 m3

 (1.25 million barrels) LNG storage tank, one associated boiloff gas condenser, and three boil-off gas compressors; 

b. three submerged combustion vaporizers, each with a peak capacity of 180 MMcfd 

(providing a total peak send-out capacity of 1,755 MMcfd for the full facility at the 

completion of phase A); and 

c. modifications to the unloading docks to accommodate new, larger LNG tankers 

and to allow simultaneous unloading of two LNG tankers. The modifications to 

the dual berthing slip include: 

• adding four mooring dolphins (two for each berth); 

• dredging approximately 72,000 cubic yards of material from the slope at the 

back of the existing slip (and disposing of dredged material into the existing 

spoil disposal area adjacent to the terminal); and 

• installing a sheet pile bulkhead at the back of the slip. 

These modifications would allow the slip to accommodate larger LNG tankers 

with an approximate overall length of 345 meters (m) (compared to the current 288 

m), breadth of 55 m (currently 49 m), design laden draft of 12.0 m (currently 11.7 

m), and displacement of 177,000 metric tons (currently 128,000 metric tons). Slip 

modifications are designed to accommodate LNG vessels capable of transporting 

up to 266,000 m3 of LNG, although carriers currently in service and delivering to 

the Elba terminal typically transport between 125,000 and 145,000 m3

. 

Phase B would be completed no later than December 2012 and would include the 

following facilities: 

a. one new 200,000 m3

 LNG storage tank; and 
Docket Nos. CP06-470-000, et al. - 3 -

b. three submerged combustion vaporizers (two for service and one spare), each with 

a peak send-out capacity of 360 MMcfd (providing a total peak send-out capacity 

of 2,115 MMcfd for the full facility at the completion of phase B). 

Each of the two phases would include all necessary ancillary equipment including related 

pumps, piping, controls and appurtenances, and associated systems (electrical, 

mechanical, civil, instrumentation, hazard detection, and fire protection) and buildings 

necessary to accommodate the associated tanks and vaporizer units. Southern LNG 

estimates that following the expansion, the terminal would receive LNG shipments about 

every 5 to 10 days, depending on natural gas demand and LNG carrier size. 

Elba Express Pipeline 

EEC plans to construct and operate about 188 miles of new natural gas pipeline and 

appurtenant facilities in Georgia and South Carolina. The pipeline would be constructed 

in two phases, extending between an interconnection with Southern near Port Wentworth, 

Chatham County, Georgia on the southern end and an interconnection with 

Transcontinental Gas Pipe Line Corporation (Transco) in Anderson County, South 

Carolina on the northern end. 

The first phase is proposed to be placed in service no later than July 2011 with a design 

capacity of 945 MMcfd, and would consist of: 

a. the “Southern Segment,” which includes about 104.8 miles of 42-inch-diameter 

pipeline extending from Port Wentworth to the existing Southern Wrens 

Compressor Station (Wrens) in Jefferson County, Georgia (to be collocated in a 

corridor with existing Southern pipelines); and 

b. the “Northern Segment,” which includes about 10 miles of 42-inch-diameter 

pipeline and 72.3 miles of 36-inch-diameter pipeline extending from Wrens to 

interconnections with Transco in Hart County, Georgia, and Anderson County, 

South Carolina. 

The second phase would also involve construction and operation of a new compressor 

station of about 10,000 horsepower near Millen, Jenkins County, Georgia. The 

compressor station would increase the pipeline design capacity by 230 MMcfd to a total 

of 1,175 MMcfd, and is proposed to be placed in service no later than January 2013. 

The Coast Guard has assessed potential risks to navigation safety and port security 

associated with the proposed project. The Coast Guard’s safety and security assessment 

is documented in the Captain of the Port’s Waterway Suitability Report (WSR). The final 

EIS includes an analysis of the environmental impacts related to the Coast Guard’s LOR 

regarding the suitability of the Savannah River for more frequent and larger LNG vessel 

operations. 
Docket Nos. CP06-470-000, et al. - 4 -

The Coast Guard Captain of the Port will issue an LOR to Southern LNG and the 

appropriate federal, state and local agencies, in accordance with 33 C.F.R. § 127.009. 

The LOR, which will be based on the Coast Guard’s WSR, is an official determination 

regarding the suitability or unsuitability of the waterway to support the proposed terminal 

expansion and associated LNG marine traffic. The Coast Guard intends to adopt all or 

portions of this EIS to serve as the NEPA analysis for the LOR. The LOR will not be 

issued until after the NEPA process has been completed.
