This map shows the general locations of Southern California Gas Company owned or operated Gas Transmission Pipelines and High Pressure (greater than 60 pounds per square inch) Gas Distribution Mains. Lower pressure distribution mains and smaller service lines connected to the gas meters at homes and businesses are not shown.
NPMS data consists of gas transmission pipelines and hazardous liquid trunklines. It does not contain gathering or distribution pipelines, such as lines which deliver gas to a customer's home. Therefore, not all pipelines in an area will be visible.
