Sulfuric Acid Leak at BWC Near Channelview

Sulfuric Acid Leak at BWC Near Channelview: Containment Failure Reaches Houston Ship Channel

A major spent sulfuric acid release at BWC Terminals’ Jacintoport-area facility near Channelview triggered a large hazmat response early December 27, 2025. Officials and company statements described a 25,000-barrel tank holding roughly 1 million gallons, with most of the product reportedly captured in on-site containment. An unknown amount exited secondary containment through drainage and entered the Houston Ship Channel, prompting federal, state, and local response and ongoing monitoring.

Incident Details

• Date: December 27, 2025

• Location: BWC Terminals (Jacintoport facility area), near the 16300 block of Jacintoport Blvd / 16335 Peninsula St, Houston, TX 77015

• Incident type: Spent sulfuric acid release and off-site impact concern

• What failed (reported): A catwalk or overhead walkway collapsed, damaging a sulfuric acid line and leading to a large release

• Volume (reported): Tank contained about 1 million gallons; officials described a “million-gallon” scale release, with most reportedly contained on-site

• Waterway impact: Unknown amount entered the Houston Ship Channel (via drainage/secondary containment exit)

• Health impact: 44 evaluated, 2 transported for respiratory issues (per local reporting)

• Response agencies: Channelview Fire Department/Fire District hazmat, Harris County, TCEQ, EPA Region 6, and U.S. Coast Guard

• Protective actions: Ship crews evacuated and a shelter-in-place for surrounding businesses was implemented (per EPA)

Incident Report

According to EPA’s incident profile, the National Response Center notified EPA Region 6 around 2:30 a.m. of a release of spent sulfuric acid from BWC Terminals. TCEQ reported off-site air impacts to nearby industrial facilities. Two ship crews in the immediate vicinity were evacuated, and surrounding businesses were placed under shelter-in-place.

Local reporting described the initiating event as a catwalk or walkway collapse that damaged a sulfuric acid line connected to a 25,000-barrel storage tank. Officials publicly referenced a tank volume of roughly 1 million gallons. Company statements indicated the majority of material went into the facility’s designated containment area, but some product entered water at the Jacintoport slip/Houston Ship Channel, with the exact amount not publicly confirmed.

EPA reported that community air monitoring for sulfur dioxide (SO2) did not exceed the incident action level during monitoring.

Why This Is a Serious Ship Channel Event

“Contained” does not mean “harmless.”

A million-gallon scale acid release is a process safety failure with real consequences:

• Workers can be injured by corrosive exposure and inhalation.

• Waterways can be impacted even when “most” is contained.

• Communities and ship crews deserve immediate, transparent answers about what entered the channel, how far it traveled, and what monitoring shows over time.

What We Still Need Answered

• What exactly caused the catwalk or walkway failure, and was it preventable?

• Why could material exit secondary containment through drainage into the Ship Channel?

• What is the confirmed volume that entered water, and what are the results of ongoing ecological monitoring?

If You Were Exposed or Worked Nearby

• Get evaluated if you had respiratory irritation, coughing, burning eyes, or throat pain.

• Document the timeline: where you were, wind direction, symptoms, and any medical visits.

• Preserve evidence: photos, texts, shift details, job assignment, and witness names.

• Do not downplay “minor” exposure. Chemical injuries can worsen after the initial event.

Key Takeaways

• A spent sulfuric acid release occurred at BWC Terminals near Channelview on Dec. 27, 2025.

• The facility involved a tank holding roughly 1 million gallons, with most reportedly contained, but an unknown amount entered the Houston Ship Channel.

• Ship crews were evacuated and surrounding businesses shelter-in-place was implemented, per EPA.

• Officials reported dozens evaluated and two transported for respiratory issues.

• The public deserves clear findings on the structural failure, containment design, and confirmed environmental impact.

Resumen en Español

El 27 de diciembre de 2025, ocurrió una fuga grande de ácido sulfúrico usado en una instalación de BWC Terminals cerca de Channelview. Reportes oficiales indican que el químico salió de un sistema asociado con un tanque de gran capacidad (aproximadamente 1 millón de galones). La empresa dijo que la mayor parte quedó dentro del área de contención, pero una cantidad no confirmada llegó al Houston Ship Channel por drenaje.

Si estuviste cerca y presentas tos, ardor en garganta, ojos irritados o dificultad para respirar, busca atención médica y documenta lo ocurrido.
