Signs of a Gas Leak

Natural gas is non-toxic, colorless, odorless and lighter than air. An odor is added to help you detect a potential gas leak. Signs include:

  • A rotten egg odor.
  • Discolored or dead vegetation over or near the pipeline.
  • A hissing, whistling or roaring sound near a gas appliance or pipeline.
  • Dirt/debris blowing into air; persistent bubbles in water-covered areas.
  • Flames (if a leak has ignited).

If a Leak Occurs

  • Leave the area immediately and warn others to stay away.
  • From a safe place, call SCE&G at 1-800-815-0083 and 911.

What NOT to Do If You Suspect a Leak

  • Do not try to turn natural gas valves on or off.
  • Do not smoke, use a lighter or strike a match.
  • Do not use any electric switch, telephone or cell phone, garage door opener or flashlight as they can cause sparks and ignite gas.
  • Do not start or stop nearby vehicles, machinery, or things that may spark.

Pipeline Safety

South Carolina state law requires that you call 811 at least three full working days before digging, and wait for technicians to mark utility lines on your property at no cost to you. If you hit an SCE&G pipeline while digging, call 1-800-815-0083 immediately.

If a pipeline is located on or near your property:

  • It is illegal to tamper with or remove SCE&G's pipeline markers.
  • Permanent structures such as storage buildings, sheds, swimming pools, or bodies of water may not be built within the right-of-way.
  • Trees may not be planted within the right-of-way.
  • Changing the ground elevation by either adding or removing soil from the right-of-way is not permitted.
SCE&G Pipeline Marker

SCE&G pipelines are located along roadways, private property and rights-of-ways that provide access to operate and maintain the system. To prevent others from digging into pipelines, SCE&G places markers at regular intervals along pipeline corridors—visible where pipelines cross roadways, streams, some property lines and other locations. The markers may not identify the exact location of the pipeline, and the absence of a pipeline marker does not mean there is not an underground pipeline. Always call 811 before digging.

Pipeline Inspections

SCE&G inspects natural gas pipelines regularly and follows the stringent requirements of the 2002 Pipeline Safety Improvement Act. Inspections may occur more frequently if the pipeline is located near densely populated areas. Usually, no interruption of service is caused by inspections. However, if repairs are needed, customers could be impacted. Property owners will be notified if work is required on their property, and all attempts will be made to minimize service disruptions.
