— CITGO Corpuse Christi Refinery Reports SO₂ Emission

CITGO reported a sulfur dioxide (SO₂) emission event at its 167,000 bpd Corpus Christi West refinery, according to an initial incident report filed with the Texas Commission on Environmental Quality on Thursday (7/16).

The event lasted approximately one hour and 40 minutes, beginning at midnight and ending at 1:40 a.m. on July 15, 2026.

According to the filing, a third-party fuel gas processing facility shut down unexpectedly, triggering flaring at the West Plant. The flaring released SO₂ through the facility’s process/emergency flare, identified as unit 573-ME1. Preliminary investigation confirmed the SO₂ emissions exceeded the reportable quantity threshold.

CITGO stated that it followed its fuel gas balance procedure in response to the incident to minimize emissions and bring the flaring event to an end.

The incident remains listed as open in the TCEQ reporting system. No injuries or additional contaminants were reported in the initial filing.
