Air Quality Monitoring: TPC Port Neches Incident

Our ambient air monitoring network routinely collects data from stationary monitors around the Beaumont area. However in response to the TPC Port Neches Plant fire, our environmental investigators are conducting hand-held monitoring in the Port Neches area.

Near real-time data are publicly available.

Posted 7:45 p.m. Nov 29
On Nov. 28, 1,3-Butadiene levels were monitored in the range of 0.0 ppb to 5.64 ppb.
As of 1:00 pm, Nov. 29, the maximum level of 1,3-Butadiene observed at the stationary monitor four miles west of the incident was 32.17 ppb, at 7:00 am. Other levels detected have been in the range of 0.00 ppb to 10.60 ppb. All 1,3-Butadiene concentrations observed at this monitor since the incident have remained well below concentrations of short-term health concern or odorous levels. Other volatile organic compounds monitored at this site have remained well below levels of health concern.

Posted 2:40 p.m. Nov. 27: 1,3-Butadiene levels at the continuous stationary monitor, located approximately four miles west of the incident, remain at or near zero parts per billion. Therefore, these concentrations are well below concentrations of health concern or odorous levels. In addition, the other volatile organic compounds monitored at this site have remained well below levels of health concern.
