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.

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.
