Pipeline markers indicate the need for extra care around natural gas transmission pipelines and some distribution lines.
These markers are usually found at roadways, railroad crossings, and other points along the pipeline route. For security purposes, pipeline markers do not show the exact location, path, depth, or number of natural gas pipelines in the area. In addition, pipelines may not follow a straight path between markers.
The markers provide a toll-free number for reporting problems 24 hours a day, 7 days a week.
Call this number if you notice any unusual or suspicious activities nearby or if you see construction-related activity and no utility personnel are on-site.
Like pipeline markers, online maps indicate the approximate locations of major natural gas pipelines.
To view these maps, visit the National Pipeline Mapping System website.
Pipeline markers and maps indicate only the general location of pipelines. Never use them as a substitute for notifying 811 to have all utility lines in your dig area located and marked.
