Underground Pipeline Markers
Natural gas companies, including Nicor Gas, install above ground pipeline markers to indicate the approximate location of buried large diameter, high pressure gas transmission lines. These line markers display the name of the pipeline operator and the telephone number where the operator can be reached in case of an emergency. Line markers are placed at public road crossings except in urban areas. Pipeline markers and warning signs indicate only the presence of a pipeline. They should not be used or relied upon to determine the exact location of the pipeline.
What We Do To Keep You Safe
Our Gas Control Operations Center continuously monitors the flow of natural gas through our pipelines and any changes in operating conditions. Our employees have the ability to adjust flows and operation pressures, and to shut off natural gas flowing in our larger pipelines.
