DEER PARK, Texas – Officials maintained Monday that the air remains safe as a fire at a Deer Park chemical facility is still burning more than 24 hours after it started.

The fire at the Intercontinental Terminal Co. facility started with two tanks about 10:30 a.m. Sunday and spread to an additional five tanks by Monday morning. Officials said Monday afternoon that the number of tanks burning was down to six, and three of those are starting to "settle down."

However, a temporary loss of water pressure overnight caused the blaze to spread to two additional tanks, bringing the total back up to eight Tuesday morning.

Harris County Judge Lina Hidalgo, flanked by other county officials, said that both station and mobile air quality monitoring is being conducted to determine when the public might need to be warned. ITC officials identified the company conducting mobile monitoring as the Center for Toxicology and Environmental Health, LLC.

Jeff Lindner, the county’s meteorologist, said that winds blowing from the east are pushing the plume to the west. He said that the plume was at an elevation of nearly 4,000 feet above Houston, but that will likely lower to about 400 feet by Tuesday morning.

Lindner said that the quality of the air would become a problem if the plume made it to the ground.

According to officials at ITC, the chemicals that are burning are components of gasoline. One of the tanks also contains a chemical called naphtha that is a component of nail polish remover and paint thinner.

Despite the black smoke pouring from the plant, ITC officials insist that the air is safe.

“We continue monitoring the air quality in and around the area, in several locations, as of this time, they’re still within normal range,” said Davis Wascome, vice president of operations for ITC. “It’s something that we’re monitoring.”

Deer Park officials lifted a shelter-in-place order for residents in the aftermath of the fire, saying no air quality tests have exceeded action levels.

Fire officials said the blaze will continue to burn until the fuel is gone or removed from the tank. That process is underway at one of the tanks.

“Pumping operations to reduce the amount of combustible material in the tank containing naphtha are ongoing,” said Alice Richardson, spokeswoman for ITC.
