Natural Gas Storage

Dominion Energy owns and operates one of the nation’s largest natural gas storage systems with about 1 trillion cubic feet of storage capacity. The storage assets are located in New York, Ohio, Pennsylvania, Utah, West Virginia, and Wyoming. For more information about natural gas storage wells and their locations, please visit your state’s environmental agency website below.


Storage Well-Specific Safety Information

Natural Gas Wellhead
  • For your safety, we require permanent structures to be kept a minimum of 100 feet from natural gas wells unless otherwise specified in the easement agreement.
  • Be aware that most of Dominion Energy's wells have pipelines connected to them. It would be a good practice to familiarize yourself with the safety regulations and recommended practices associated with natural gas pipelines.
  • If you suspect a problem, please call the local Dominion Energy 24-hr emergency number:
    • Dominion Energy Ohio - 1-800-535-3000.

Program Strategy - Integrity Management

Dominion Energy supports a culture of integrity management in order to align itself with the spirit of the regulation. In compliance with 49 CFR Part §192.12, we will support storage asset integrity activities with (1) a written Storage Integrity Management Program, (2) analysis, and (3) the evaluation and performance improvements necessary to manage risks to the integrity of our storage systems.

Storage Integrity Management Program

Dominion Energy has always placed a high priority on safety and compliance. We embrace the goals of improving natural gas storage safety and raising the public confidence with natural gas storage as it continues to ensure safe operations of its infrastructure, and comply with the federal requirements for a storage integrity management program. A full background of the Interim Final Rule is found on the PHMSA Underground Natural Gas Storage webpage.


Recognizing a Leak

Sight: Discolored or abnormally dry soil/vegetation, continuous bubbling in wet or flooded areas, and vaporous fogs or blowing dirt around a well or pipeline area can all be signs of a release. Dead or discolored plants in an otherwise healthy area of vegetation or frozen ground in warm weather are other possible signs. Natural gas is colorless, but vapor and ground frosting may be visible at high pressures.

Sound: Volume can range from a quiet hissing to a loud roar depending on the size of the leak and pressure of the system.

Smell: A rotten egg odor will sometimes accompany natural gas leaks. Gas in transmission pipelines and wells are not required to contain odorant, though many companies do transport odorized natural gas.

Actions to Take if a Leak Occurs

  • Leave the area immediately, heading upwind. Do not touch, breathe or contact leaking liquids or gases.
  • Do not light a match, start and engine, use a telephone, operate on/off switches or do anything that may create a spark.
  • From a safe location, call 911 or your local emergency response number and then the pipeline company. Be ready to provide your name, telephone number, a description of the leak and its location.
  • Do not drive or enter a leak or vapor cloud area. Do not attempt to stop the leak by operating storage well equipment. Warn others if necessary. Remember, report even a scrape or dent on well equipment or a pipeline to the company. If not promptly reported or repaired, it could result in a future leak or serious incident.
