The Houston Ship Channel reopened after closing Thursday because of a leak of 500 gallons of a chemical compound.
The chemical was benzene, a compound found in crude oil, and the U.S. Coast Guard and the Harris County Hazardous Material Response Team are investigating just how the spill occurred.
The spill came from the tanker Maritime Jingan, moored at the Vopak Terminal.
The Vessel Traffic Service closed a portion of the Houston Ship Channel between the Lynchburg Ferry Crossing and Carpenters Bayou at 12:20 p.m. That portion reopened at 2:40 p.m.
Officials identified the spill around noon. The leak ended up quickly secured and only a small portion of the benzene entered the water, according to the U.S. Coast Guard.
