Enterprise Products Operating LLC Dixie PL Hydrotest Pipeline, Dexter, Mississippi | Refined Product Pipeline Infrastructure

The Enterprise Products Operating LLC Dixie PL Hydrotest pipeline segment spans from milepost 315.0 to milepost 367.5 in Dexter, Walthall County, Mississippi. This refined product pipeline is part of the extensive Dixie Pipeline system, which transports propane and other natural gas liquids across the southeastern United States. The facility is operational and falls under the regulatory oversight of the Pipeline and Hazardous Materials Safety Administration (PHMSA) and DOT 49 CFR Part 195 for hazardous liquid pipelines. As a refined product pipeline, this segment is designed to safely transport petroleum products such as gasoline, diesel, and jet fuel. The pipeline infrastructure includes cathodic protection systems to prevent corrosion and is subject to regular hydrostatic testing to ensure integrity. The 52.5-mile segment is part of a larger network that connects refineries and distribution terminals, supporting regional fuel supply. The pipeline plays a critical role in the energy infrastructure of Mississippi and the broader Gulf Coast region. It facilitates the efficient movement of refined products from refining centers to consumer markets, contributing to energy security and economic activity. The facility's location in a rural area with proximity to waterways necessitates robust environmental safeguards to prevent spills and protect local ecosystems.

The pipeline segment traverses rural areas in Walthall County, Mississippi, near the Pearl River watershed. Proximity to waterways and agricultural land requires careful monitoring to prevent leaks that could impact water quality and soil. The region's humid subtropical climate with heavy rainfall increases erosion and corrosion risks, making cathodic protection and regular inspections essential for environmental protection.
