Sulfuric Acid Leak in Channelview: Officials Provide Update on Environmental Monitoring and Response

Sulfuric Acid Release Incident

• ⚠️ A significant release of approximately one million gallons of sulfuric acid occurred early Saturday morning in Channelview.
• 💥 The incident began when a walkway collapsed, rupturing a pipeline and causing a valve failure at a BWC terminals facility.
• 🚢 The leak impacted a portion of the Houston Ship Channel, affecting two docked ships, though the channel remains open.

Public Safety and Air Monitoring

• 💨 Initial concerns focused on air quality, with Harris County Pollution Control conducting extensive monitoring.
• 🚫 One high reading was determined to be an error, and subsequent readings in surrounding communities have been fine, attributed to distance and dissipation.
• 📍 A perimeter has been established to ensure the safety of first responders and neighboring facilities.
• 🧑‍⚕️ Forty-four individuals were checked and released, with two transported for evaluation and subsequently released.

Environmental Impact Assessment

• 🌊 The sulfuric acid is diluting in the Ship Channel, and there are no immediate concerns for recreational water users.
• 🐠 Monitoring for impacts on aquatic life is ongoing, with no sightings of dead fish reported thus far.
• 🔬 The incident is still considered ongoing, though significantly abated, with investigators assessing the cause and potential actions.

Response and Collaboration

• 🤝 A unified command involving federal, state, and local agencies, including the US Coast Guard, EPA, and TCEQ, is managing the response.
• 🗣️ BWC terminals is cooperating with authorities, conducting its own monitoring, and working on remediation efforts.
• 🛠️ The company stated it has not experienced a similar incident before and is working with authorities on evacuation procedures.

Material Hazard and Mitigation

• 🧪 The released material is identified as approximately 98% pure spent sulfuric acid, a hazardous substance.
• 🌡️ The reaction of sulfuric acid with water is exothermic, creating water vapor and other byproducts like SO2, which was monitored.
• 💧 Due to the product's solubility in water, traditional containment methods like booms are ineffective; mitigation focuses on managing the source and allowing for natural dilution and dissipation.
