DEER PARK, TX – Today, the first report from the Energy Transfer pipeline breach and fire was filed with the Texas Commission on Environmental Quality (TCEQ) (see Air Emission Event Report Database Incident 429855). This is the community’s first view into what has been leaking into the air since Monday morning.

Air Alliance Houston is expecting further data from the company, but our review of their first report shows:

• 330,621 pounds of Volatile Organic Compounds (VOC) and 68,780 pounds of Nitrous Oxide (NOx) were emitted, which can combine with sunlight to produce Ozone.
• 143,278 pounds of N-pentane and 108,408 pounds of Isobutane were emitted, both certified Special Health Hazard Substances by multiple federal agencies, including the US-EPA and OSHA. Exposure can cause irritation to the nose, throat, eyes, skin, and lungs.
• 137,310 pounds of Carbon Monoxide, caused by incomplete combustion of the gas in the pipeline. When emitted outdoors, Carbon Monoxide is less likely to impact human health; however, it is a heat-trapping gas and one of the Criteria Air Pollutants regulated by the US-EPA.

It should be noted that these data are self-reported from Energy Transfer and not verified by a third-party. Based on the company’s own account, these numbers are “conservative,” and final emissions amounts will likely be higher. Regardless, it is clear that a significant amount of chemicals were leaked into the air as a result of this pipeline breach, calling into question early statements made by the company and by some local officials that there is “no harm” to air quality.

People in the vicinity of the incident should continue to take precautions. If community members are feeling any adverse or unusual health effects, please consult a medical professional.
