At approximately 0200 (local) 27DEC25, there was a sulphuric acid release at Black Water Contanda Jacinto Port.  At the moment the amount is unknown but there is the potential for a couple thousand gallons.  The material falls under the I category on the respiratory irritant scale which signifies substances/processes damaging the airways by causing inflammation, triggering cough/sneeze reflexes, or leading to systems like wheezing, congestion, or shortness of breath, affecting nose, throat, and lungs.  Based of a plume diagram prediction from the National Weather Service, with the winds being out of the south west, the plume is possible to reach Carpenters Bayou, Old River, and San Jacinto River.  Vessel Traffic Service Houston Galveston recommends keeping all crew members inside near the affected area. VTS will not accept any vessels transits into the Jacinto Port Slip until further notice.

Very respectfully,
