Crews are assessing the amount of diesel fuel that has leaked into the water near the site of where the fishing vessel Pappy's Pride and 600-foot tanker Bow Fortune collided, Galveston County officials said.
The county learned fuel from Pappy's Pride had leaked Wednesday morning, county spokesman Zach Davidson said.
Crews are working conduct cleanup operations as quickly as possible, Galveston County Judge Mark Henry said Wednesday afternoon.
Crews are still searching for two missing people, officials said.
The ship channel is still closed to boat traffic to the Port of Galveston, Texas City and Houston, officials said.
Update, 12 p.m.
The search for two missing mariners has shut down all traffic in the Houston and Galveston Ship Channels, according to the Coast Guard Vessel Traffic Service.
The Coast Guard has shut down the channels for search and rescue and salvage operations to occur, said Steve Nerheim, the director of the vessel service.
The channels were closed in the hours after the collision on Tuesday night, officials said.
The closure means that cruise ships can't leave the Port of Galveston and that chemical and oil tankers traffic can't go to the Port of Texas City.
Search and rescue teams are still looking for two crew members who fell overboard after their fishing vessel collided with a petrochemical tanker near the Galveston jetties late Tuesday, according to the U.S. Coast Guard.
The crash happened when the 81-foot Pappy’s Pride and the 600-foot tanker Bow Fortune collided in fog just before 3:30 p.m., capsizing the smaller boat and sending four of its crew overboard, U.S. Coast Guard Petty Officer 2nd Class Johanna Strickland said.
One of boat crew members died Tuesday and one was taken a University of Texas Medical Branch hospital before 6 p.m., Galveston Island Beach Patrol Chief Peter Davis said.
The crew of a good Samaritan vessel and of a Coast Guard medium response boat had pulled two of the crew members from the water and transferred them to emergency medical services personnel, according to the Coast Guard.
The surviving crew member was taken to the hospital with a broken leg, he said.
The Coast Guard, the beach patrol, the Galveston County Sheriff’s Office were searching Wednesday for the two still missing, Davis said.
The cause of the crash is under investigation, Strickland said.
Lingering fog Wednesday was impeding the search, Davis said.
