ExxonMobil paid $616,000 to resolve alleged environmental violations stemming from an April 2013 fire at the company’s oil refinery in Beaumont, Texas, which occurred when workers used a torch to remove bolts from the top of a device called a heat exchanger. An inspection following the incident disclosed violations of the Clean Air Act and of the regulations known as the Chemical Accident Prevention Provisions. In addition to the civil penalty, Exxon also agreed to hire an independent auditor to conduct a compliance audit at the refinery, and to purchase a hazardous materials incident command vehicle, valued at $730,000, for the Beaumont fire department.
