Subsidence monitoring is a crucial component to understanding cavern integrity of salt storage caverns. This report looks at the historical and current subsidence monitoring program and includes interpretation of the data from the Bayou Choctaw Strategic Petroleum Reserve site. The current monitoring program consists of an annual elevation survey as well as GPS and tiltmeter instruments above both Cavern 4 and Cavern 20. This year's level and rod survey indicates little subsidence across the site. In addition, the GPS and tiltmeter instruments do not indicate any substantial movement above caverns 4 and 20. As such, there is no reason to indicate any of the caverns at Bayou Choctaw have lost integrity.
