Transcontinental Gas Pipe Line Co., LLC - 145-21 Valve Setting is a gas pipeline facility located at 7720 NC 73, Stanley, Lincoln County, North Carolina. It is part of the Transcontinental Gas Pipe Line (Transco) system, one of the largest natural gas pipeline networks in the United States, spanning over 10,000 miles. This valve setting serves as a control point for gas flow and pressure regulation along the pipeline. The facility operates under the regulatory framework of the US Pipeline and Hazardous Materials Safety Administration (PHMSA) and Department of Transportation (DOT) 49 CFR Part 192, which governs the safe transportation of natural gas. The NAICS code 486210 indicates it is classified as pipeline transportation of natural gas. Typical valve settings on the Transco system include automated valves for emergency shutdown and pressure monitoring. This valve setting plays a critical role in maintaining the integrity and reliability of the Transco pipeline, which supplies natural gas to markets in the southeastern United States. Its location in Lincoln County places it within a region with moderate population density, requiring adherence to strict safety standards for pipeline operation and maintenance.

The facility is situated in a rural area near Stanley, North Carolina, with proximity to Lake Norman and the Catawba River watershed. Pipeline infrastructure in this region must manage risks related to waterway crossings and soil erosion. The commodity transported (natural gas) poses low environmental risk compared to hazardous liquids, but methane leakage is a concern. Cathodic protection systems are typically employed to prevent corrosion, and regular inspections are mandated by PHMSA.
