the regulations as critically important. These reliability ele-
ments include:
• Data management and action plans for both risk man-
agement and emergency response.
• Exposure, including proximity to infrastructure and
previous blowout events at the site.
• Reservoir and cavern integrity, including adequate top
and side seals for pressure integrity.
• Area-of-review monitoring, including surface methane, observation wells, and induced seismicity.
• Operations, including management of change and
training of operational personnel.
