NOx release at Austin Powder


There has been a release of nitrogen oxides from Austin Powder’s Red Diamond plant in Ohio. The company says that the decomposition of nitric acid caused the incident due to elevated temperatures inside a 5,000-gallon storage tank. This led to a visible release of nitrogen oxide gas, which was vented through the plant’s built-in safety systems. Austin Powder says that its team activated emergency response protocols and notified the Ohio Environmental Protection Agency (EPA). Air quality modelling conducted at the property’s fence line confirmed that NOx levels remained below health-hazard thresholds. The company is conducting an internal investigation to determine the root cause of the temperature rise that led to the gas release.
