Dickinson Bayou will remain closed until further notice while clean up crews work to remove a waste mixture from the water surface, police spokesman Sgt. Tim Cromie said.
Less than 250 gallons of a substance — a mixture of oily water, sulfonate solution and emulsifiers — spilled Saturday from a broken valve at the Calumet Penreco refinery, 4401 Park Ave., in Dickinson, Cromie said.
Police said the substance spilled as the result of a valve that froze during last week’s icy weather. The waste mixture is nonflammable and nonhazardous, Cromie said.
Response teams have placed containment booms east of the refinery and near Paul Hopkins Park, completely across the bayou, Cromie said. The bayou is closed to watercraft, he said.
Police don’t have an exact estimate of cleanup time, Cromie said.
