The Coast Guard has reopened all shipping lanes of the Houston Ship Channel to daylight-hour traffic, Bloomberg reports. Shipping traffic in the channel has mostly ground to a halt since a Saturday vessel collision that caused about 4,000 barrels of fuel oil to spill into the channel and Galveston Bay. A representative from Houston Ship Pilots told Bloomberg traffic would be “back to normal” once nighttime traffic resumes in a couple of days. ExxonMobil’s Baytown refinery has resumed receiving crude oil shipments. Other major refiners in the area have not commented publicly about how the spill has affected their operations.
