Representatives from 3 Rivers Energy Partners attended the Planning and Zoning Commission meeting on Feb. 4 to provide updates on the facility’s progress, cleanup efforts, and safety measures following a tank rupture at the anaerobic digester on Sept. 10, 2024.
3 Rivers General Manager Marshall Miller said an investigation revealed a bolt failure was the primary cause of the rupture. He added that an ongoing lawsuit addresses the failure, and the company is working internally to prevent similar incidents.
One concern discussed was the safety measures in place regarding gas lines near Moore County High School. Gas lines on Goodbranch Road are 770 feet from the school, while those along Highway 55 are 720 feet away.
Miller assured board members that both lines are equipped with remotely controlled shutoff valves, which can be activated quickly in the event of a leak.
Current safety recommendations advise sheltering in place rather than evacuating in the case of a gas-related emergency.
3 Rivers also is consulting with environmental specialist Tony Grow on the strategic placement of a safety berm. The company anticipates purchasing the adjoining Dickey farm on Goodbranch Road, where a surge wall would help contain potential spills.
Additionally, vegetation buffers will be established at both ends of the property to provide an added layer of environmental protection. Miller emphasized that 3 Rivers remains committed to environmental responsibility and cooperation with county officials to ensure the safe and successful completion of its projects.
Moore County is finalizing a contract with Grow Environmental Solutions to oversee environmental compliance for the 3 Rivers project and the Silicon Ranch solar farm development. Committee chairman Dexter Golden noted the contract was near completion.
