A report analyzing the potential vulnerabilities of natural gas storage facilities and ways to address them was released this week by a group of states organized by the Interstate Oil and Gas Compact Commission and Ground Water Protection Council.
There are currently more than 400 active underground gas storage facilities in the U.S. with more than 80 percent of the country's gas storage in depleted oil or natural gas reservoirs.
The 130-page report, “Underground Gas Storage Regulatory Considerations” is intended to provide a resource for regulatory agencies and includes input from experts in academia, industry, non-profit organizations, and other state and federal agencies. It addresses the regulatory framework of underground gas storage, risk management, state permitting, well drilling and construction, well integrity, reservoir integrity, monitoring, and emergency response planning among other topics.
“A lot of thought and expertise went into this report,” said Hal Fitch, co-chair of the group and division director for Michigan’s Oil, Gas, and Minerals Division, Department of Environmental Quality. “We believe it will be a great resource for state and federal agencies as they work to enhance their oversight of gas storage in the U.S.”
