On June 14, 2021, at approximately 6:50 a.m., an accidental release of mineral oil occurred. The mineral oil ignited, causing a fire. The event resulted in $380 million in property damage and the permanent closure of the facility. Before the incident, the facility employed approximately 200 people.
Leading up to the incident, the facility had hired a contractor to replace insulation on its heating oil piping system. To reach a portion of this piping, the contractor used a scissor lift. As the contractor began raising the scissor lift near the work location, the top guardrail of the lift impacted a section of a ½-inch piping assembly that included a valve. This threaded piping was connected to a four-inch pipe containing mineral oil, which was part of a hot oil system that provided heating for
other process equipment.
