On November 27, 2019, a major loss of containment event occurred that resulted in multiple fires and explosions at the TPC Group (TPC) Port Neches Operations (PNO) facility in Port Neches, Texas. The U.S. Chemical Safety Board released a factual update detailing the incident.

The TPC PNO facility manufactured 1,3-butadiene and raffinate-1. The incident occurred in the facility’s South Unit. The initial explosion resulted in injuries to two TPC employees and a security contractor and caused significant damage to the facility. Following the incident, county officials issued a mandatory 4-mile radius evacuation order, which remained in effect until 10:00 a.m. on November 29, 2019.

Because of the incident, TPC has decided to transition to a “terminal and services” operation while they evaluate and plan to rebuild. As part of this transition, TPC terminated the employment of multiple workers and supervisors.
