Call before you dig  

Do not assume you already know the location or depth of a pipeline. Pipeline markers may not indicate its precise location. Please contact your local One Call Center at least 48 hours before starting the work. The Common Ground Alliance provides state-specific information and a list of best practices. Learn more about local pipelines from the National Pipeline Mapping System.

If you make any contact—however minor—with one of our pipelines during your excavation work, please call us immediately at 1-800-537-5200, so we can check for possible damage. Thank you for helping all of us remain safe.
