Energy Transfer gave an update late Monday evening, hours after the blast off in the 9000 block of Spencer Highway.
As of 10 p.m., the company said flames were still burning but reduced. It added that no air monitoring issues were reported.
The update comes after Deer Park police said that an SUV hit an above-ground pipeline valve. Preliminary reports also suggests no terroristic activity and that it was an isolated incident, police added.
According to police, the SUV drove through a fence on the west side of a nearby Walmart parking lot in the 9000 block of Spencer Highway. The vehicle entered the adjacent pipeline right-of-way and hit the valve.
Police are working to identify the vehicle and the driver.
The resultant explosion started in Deer Park and then spread south under Spencer Highway to La Porte, as the highway separates Deer Park to the north and La Porte to the south.
Multiple agencies responded to the scene, including the Deer Park Office of Emergency Management, which handled the west side of the fire, and La Porte, which handled the east side.
Energy Transfer, the company that owns the pipeline, said liquid natural gas is burning, and it will be hours before the fire burns off.
Energy Transfer sent Eyewitness News the following statement:
"We experienced an incident this morning in La Porte, Texas, at a valve station along Spencer Highway for a 20" natural gas liquids line that resulted in a fire. There are no reports of injuries at this time. The LaPorte Fire Department is on the scene and has evacuated all homes and businesses within a half mile of the incident site. The line has been isolated so that the residual product in the line can safely burn itself out. We have no timeline at this point on how long that process will take, but we are working closely with local authorities. We are aware of early reports indicating that an unknown passenger car entered our right-of-way and struck the value location. Air monitoring equipment is in the process of being set up in the area. We will continue to release details as they become available."

A Deer Park official told ABC13's Daniela Hurtado that four people were injured from the event, including a firefighter for minor injuries. The four also includes two hospitalizations and two heat-related injuries.
The flames grew at one point, creating smaller grass fires that crews are working to keep under control. City officials said the impact zone is about 1/2 mile from the fire itself.
During a press conference, Deer Park Mayor Jerry Mouton said the fire is in a contained area, but local authorities have implemented evacuations and shelter-in-place orders for nearby areas, including HEB, Walmart, Heritage Elementary, College Park Elementary, James H. Baker, San Jacinto College.

The adjacent property is owned by Coastal Industrial Water Authority. However, the company's executive director told Eyewitness News that "the fire is not associated with CWA."
As for air monitoring, Harris County Precinct 2 shared that it plans to display live readings soon on its dashboard. When the measurements are taken, they will populate the map using the aforementioned link.
Keep in mind that the readings you will see are meant to be a comparison based on historical "base readings." They are not a determination of how good or bad the air quality is, but rather a way to see spikes in the hourly readings, Harris County Pollution Control said.
According to Harris County Property Records, the fire is happening on or right near a CenterPoint-owned property.
"CenterPoint Energy is monitoring the incident on Spencer Highway in LaPorte, which is unrelated to the company's natural gas operations or equipment. We are also cooperating with first responders. Putting safety first, the public should avoid this area until further notice from local emergency officials. When it is safe to do so, our electric crews will go into the area to assess the damage to our transmission and distribution power lines, poles and equipment and begin restoring service to impacted customers as safely and quickly as possible," CenterPoint told ABC13 in a statement.

Therefore, we are unable to transport those children home by bus.
