Energy Transfer releases first emissions report from La Porte pipeline fire
Adam Zuvanich / Houston Public MediaA pipeline explosion in La Porte has resulted in several businesses and schools evacuating as emergency responders try to contain the fire.After burning for four straight days, the owner of the pipeline that burst Monday in La Porte has released their first report on what chemicals could have been released into the air as a result. According to the company's report, submitted to the Texas Commission on Environmental Quality, the pipeline fire emitted the following chemicals during a 10-hour period on Monday. 330,621 pounds of Volatile Organic Compounds (VOC) 68,780 pounds of Nitrous Oxide (NOx) 143,278 pounds of N-pentane 108,408 pounds of Isobutane 137,310 pounds of Carbon Monoxide This is only the initial, conservative, report and the company said a final one will provide further details. Currently, no date has been released for when it might be released. The pipeline fire began Monday morning around 10 a.m. after a vehicle drove through a fence and struck the above-ground pipeline valve, according to the City of Deer Park Emergency Management Office. On Thursday, officials announced that human remains were discovered inside the SUV that reportedly struck the pipeline. Four people, including a firefighter, were also injured as a result of the fire. A criminal investigation is ongoing into the incident, terrorism was eliminated early on as a possible motive. Air Alliance Houston, a public health advocacy organization, released a statement regarding the initial report and said that some of the chemicals are known to have possible adverse health effects. Air Alliance said the U.S. Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration both identify N-pentane and Isobutane as a special health hazard substance that can irritate the nose, throat, eyes, skin and lungs. According to an EPA report on N-pentane, the chemical could pose a danger to humans and animals. However, the EPA's website says the report should be considered preliminary since the data regarding N-pentane's toxicity is limited. Gunnar Schade, a professor at Texas A&M University's Department of Atmospheric Sciences, told Houston Public Media that there were likely many more pollutants than the ones listed in the initial report. "The compounds listed would be the ones straightforwardly assumed for reasons of combustion," he said in a statement. "It appears the assumption was made that methane, ethane, and propane were completely combusted. ... As was obvious from the video footage, large amounts of soot were also produced, which is both a strong warming agent and consists of potentially harmful particulate matter." Schade also said that formaldehyde and benzene, two even more toxic chemicals compared to butanes and pentanes could have been produced by the flame as a result of incomplete combustion. On Tuesday morning, before the release of the preliminary report, the La Porte Office of Emergency Management released a statement on social media stating that multiple agencies were on the scene monitoring the air. "A third-party air monitor contracted by Energy Transfer and Harris County HazMat has checked San Jacinto College and both La Porte ISD campuses to ensure the safety of students and staff," the statement said. "At this time, there are no significant health concerns for the community." At 7:10 p.m. Thursday, the City of Deer Park and the City of La Porte released a joint statement announcing that the fire had been extinguished. "Energy Transfer, Harris County Pollution Control and third-party vendors hired by the county continue air monitoring activities," the Thursday statement said. "The Texas Department of Emergency Management (TDEM) has been in the [area] this week and will return on Monday to walk the affected areas and visit with the public about the remaining needs." Officials also announced Thursday evening that the majority of residents and business owners had been able to return to their homes and/or workplaces.
The pipeline fire burned for four days and resulted in the death of one person and the injury of four others.
