Southern Natural Gas Company LLC, Gwinvi - Gas Pipeline in New Hebron, Mississippi

Southern Natural Gas Company LLC, Gwinvi is a gas pipeline facility located at 1064 Sonat Road in New Hebron, Jefferson Davis County, Mississippi, United States. The facility is operational and classified under NAICS codes 221210 (Natural Gas Distribution) and 486210 (Pipeline Transportation of Natural Gas), indicating its role in both local distribution and interstate transmission. The facility operates under the regulatory oversight of the Pipeline and Hazardous Materials Safety Administration (PHMSA) and the Department of Transportation (DOT), specifically 49 CFR Part 192 for gas pipelines. This regulatory framework mandates rigorous safety standards including pipeline integrity management, corrosion control, and emergency response protocols. As part of the Southern Natural Gas system, this facility contributes to a major natural gas pipeline network serving the southeastern United States. The Gwinvi facility supports regional energy infrastructure by transporting natural gas to industrial, commercial, and residential consumers in Mississippi and beyond. Its location in a rural area of Jefferson Davis County minimizes proximity to dense populations, though pipeline safety remains a priority through regular inspections and cathodic protection systems. The facility's operational status ensures continued reliability in the natural gas supply chain.

The facility is situated in a rural area of Mississippi, near the Pearl River watershed. Pipeline operations involve the transport of natural gas, which poses risks of leaks or ruptures that could affect local waterways and ecosystems. Regulatory requirements under PHMSA mandate leak detection, corrosion prevention, and spill response plans to mitigate environmental impact. The surrounding land use is primarily agricultural and forested, with limited population density, reducing potential exposure to communities.
