Mississippi Crossing Project is a pipeline project that is planned to be developed to address natural gas demand and support distribution in Southeast region of the US, especially in the states of Mississippi, Alabama, and Georgia.
The project is being developed by Tennessee Gas Pipeline (TGP) Company, a unit of energy infrastructure company Kinder Morgan.
Recommended White Papers
In November 2024, TGP filed a request seeking approval to use the Federal Energy Regulatory Commission’s (FERC) pre-filing process for the pipeline.
The company took the Final Investment Decision (FID) on Mississippi Crossing Project (MSX) in December 2024.
The FID was announced after the company finalised long-term, binding transportation agreements with customers for the full capacity of the pipeline.
The construction of the 206-mile-long pipeline is expected to entail an investment of around $1.4bn. This investment forms part of Kinder Morgan’s $3.1bn expansion strategy, which includes the SNG South System 4 Expansion.
Subject to necessary permits and clearances, the project is expected to begin services in November 2028.
The pipeline, stretching from Mississippi to Alabama, will be connected to the existing TGP system and third-party pipelines, enabling access to key supply basins.
In August 2024, environmental, safety, and public awareness training of field crews was carried out. Civil and environmental surveys were undertaken in September 2024 and is expected to continue through February 2025.
Mississippi Crossing Project Route
The Mississippi Crossing Project will begin near Greenville, Mississippi and conclude near Butler in Alabama.
It will pass through Humphreys, Sunflower, Washington, Attala, Holmes, Clarke, Leake, Newton, Lauderdale and Neshoba counties in Mississippi, and Choctaw County in Alabama.
The pipeline will transport natural gas from Tennessee Gas Pipeline’s (TGP) 100 Line near Greenville to Southern Natural Gas Company (SNG) south mainline near Rose Hill/Meridian, Mississippi and to Transcontinental Gas Pipe Line Company’s (Transco) Station 85 near Butler.
The new pipeline will also have lateral interconnections with Texas Eastern Transmission and Texas Gas Transmission near Kosciusko, Mississippi.
Mississippi Crossing Project Infrastructure
The MSX Project will involve laying approximately 206 miles of greenfield pipeline.
This will include around 178 miles of 42-inch diameter natural gas pipeline passing through Humphreys, Sunflower, Washington, Attala, Holmes, Clarke, Leake, Newton, Lauderdale, and Neshoba counties in Mississippi.
A 6-mile long 36-inch diameter natural gas pipeline section will be in Humphreys and Sunflower counties, Mississippi.
The final section will be 22-mile long 36-inch diameter pipeline passing through Clarke County, Mississippi and Choctaw County, Alabama.
The project will feature three new compressor stations with a combined capacity of 183,000 horsepower. The stations will be situated in Humphreys, Attala, and Lauderdale counties.
There will be four new meter stations with tap, metering, heating, flow control, and communications facilities, at interconnections with other pipeline systems.
Additionally, the system will include three overpressure protection facilities with clamp on meters.
Once complete, the MSX project will enable the transportation of approximately 1.5 billion cubic feet per day (Bcf/d) of natural gas.
The project will create 750 temporary construction jobs and 15 permanent roles.
Contractors Involved
TGP involved Environmental Consultants (SWCA) as the primary contractor for managing the environmental aspects of the pipeline project.
This includes natural and cultural resource surveys, preparation of the draft ER and the final ER, federal and state permit applications, environmental justice analysis for the Project area, and Waters of the United States (WOTUS), cultural resource, and threatened and endangered species consultations.
TRC Pipeline Services will provide right-of-way services for the Mississippi Crossing Project related to land ownership, notifications of surveys, and eventual acquisition of rights-of-way/easements among others.
TKE Engineering and Design was hired for civil surveys, while Trinity Consultants will carry out an analysis of the air emission impacts for the project.
