Project Summary

Tennessee Gas Pipeline Company (“Tennessee”), a subsidiary of El Paso Corporation, plans to increase the capacity of its 300 Line to transport new diversified natural gas supplies, including newly accessed Appalachian and Marcellus shale gas to serve the growing demand for interstate natural gas transmission service in the northeastern United States. The 300 Line Project (“Project”) involves the installation of seven looping segments in Pennsylvania and New Jersey totaling approximately 128 miles of 30-inch pipeline, and the addition of approximately 55,000 horsepower (“HP”) following the installation of two new compressor stations and upgrades at seven existing compressor stations. The additional HP will be constructed at two new compressor stations to be located in northwestern Pennsylvania, at two existing compressor stations in Pennsylvania, and at an existing compressor station in New Jersey. Additionally, Tennessee will upgrade or restage compressors at three existing stations, and add a filter separator to one existing compressor station. At the same time, to capture efficiencies and increase reliability, Tennessee will replace HP at four of the previously mentioned existing compressor stations.

Upon completion, Tennessee expects that the Project will increase natural gas delivery capacity in the region by approximately 350,000 dekatherms per day. The Project will provide access to diversified natural gas supplies from Gulf Coast, Appalachian, Rockies, and Marcellus Shale supply areas with gas deliveries to points along Tennessee’s mainline system and to various interconnections with other pipelines in northern New Jersey, as well as deliveries into jointly owned local distribution company facilities at an existing interconnect with Consolidated Edison in White Plains, New York.

To minimize impacts from construction, the planned pipeline route will generally follow an existing Tennessee pipeline corridor wherever practicable. Tennessee expects its construction efforts will meet all applicable local, state, and federal regulatory safety requirements and environmental regulations.

Tennessee held two open seasons for this Project (one in 2008 and one in 2009) and has executed a binding Precedent Agreement with a shipper for the full capacity of the Project. In October 2008, Tennessee submitted its request to the Federal Energy Regulatory Commission (FERC) to use its pre-filing process, which was granted in November 2008. As part of the pre-filing process, Tennessee conducted nine open house meetings in the Pennsylvania and New Jersey counties that will be affected by the Project, and participated in three FERC scoping meetings. On July 17, 2009, Tennessee filed its certificate application requesting FERC approval of the Project.

Following receipt of all applicable approvals, construction may begin in the second half of 2010. The Project is planned to be in service by November 2011. Tennessee expects its outreach efforts will continue throughout the construction phase of the Project.

Tennessee has been serving the northeastern United States for more than 50 years. The success of this Project will continue to build upon Tennessee’s long tradition of providing reliable energy service to the region. The Project will support Tennessee’s commitment to serve growing markets with safe and reliable deliveries of natural gas.

El Paso Corporation provides natural gas and related energy products in a safe, efficient, and dependable manner. El Paso owns North America’s largest interstate natural gas pipeline system and one of North America’s largest independent natural gas producers.
