What to know about the pipeline fire burning for a third day in Houston's suburbs

DEER PARK, Texas (AP) — A pipeline fire that forced hundreds of people to flee their homes in the Houston suburbs burned for a third day Wednesday, with no official timeline for when it might be extinguished.

Authorities have offered few details about what prompted the driver of an SUV to hit an aboveground valve on the pipeline on Monday, sparking the blaze.

Here are some things to know about the situation with the pipeline fire:

Officials say the underground pipeline, which runs under high-voltage power lines in a grassy corridor between a Walmart and a residential neighborhood in Deer Park, was damaged when the SUV driver left the store's parking lot, entered the wide grassy area and went through a fence surrounding the valve equipment.

Authorities have offered few details on what caused the vehicle to hit the pipeline valve, the identity of the driver or what happened to them. The pipeline company on Wednesday called it an accident. Deer Park officials said preliminary investigations by police and FBI agents found no evidence of a terrorist attack.

Deer Park police won't be able to reach the burned-out vehicle until the flame has been extinguished. Once the area is safe, the department will be able to continue its investigation and confirm specifics, city spokesperson Kaitlyn Bluejacket said in an email Wednesday.

The valve equipment appears to have been protected by a chain-link fence topped with barbed wire. The pipeline's operator has not responded to questions about any other safety protections that were in place.

Energy Transfer is the Dallas-based owner of the pipeline, a 20-inch-wide (50-centemeter-wide) conduit that runs for miles through the Houston area.

It carries natural gas liquids through the suburbs of Deer Park and La Porte, both of which are southeast of Houston. Energy Transfer said the fire had diminished overnight and was continuing to “safely burn itself out” on Wednesday.

Energy Transfer also built the Dakota Access Pipeline, which has been at the center of protests and legal battles. The company’s executive chairman, Kelcy Warren, has given millions of dollars in campaign contributions to Republican Texas Gov. Greg Abbott.

Energy Transfer said its crews were working Wednesday to install specialized isolation equipment on both sides of the damaged section that will help extinguish the fire.

Once the equipment is installed, which could take several hours of welding, the isolated section of the pipeline will be purged with nitrogen, which will extinguish the fire, company and local officials said. After that, damaged components can be repaired.

“The safest way to manage this process is to let the products burn off,” Energy Transfer said.

Authorities evacuated nearly 1,000 homes at one point and ordered people in nearby schools to shelter in place. Hundreds of customers lost power. Officials said Wednesday afternoon that only two customers remained without electricity in the Deer Park and La Porte area. Repairs to all of the power distribution lines affected by the fire had been completed.

Deer Park's statement said Energy Transfer was “prioritizing the safety of the community and environment as it implements its emergency response plan.”

By late Tuesday, about 400 evacuees remained, and some expressed frustration over being forced to quickly flee and not being given any timeline for when they will be able to return.

“We literally walked out with the clothes on our backs, the pets, and just left the neighborhood with no idea where we were going,” said Kristina Reff, who lives near the fire. “That was frustrating.”

Energy Transfer and Harris County officials have said that air quality monitoring shows no immediate risk to individuals, despite the huge tower of billowing flame that shot hundreds of feet into the air, creating thick black smoke that hovered over the area.

Houston is the nation’s petrochemical heartland and is home to a cluster of refineries and plants and thousands of miles of pipelines. Explosions and fires are a familiar sight, and some have been deadly, raising recurring questions about industry efforts to protect the public and the environment.

DENVER (AP) — A Frontier Airlines plane hit and killed a pedestrian on the runway of the Denver International Airport during takeoff, airport authorities said, sparking an engine fire and forcing passengers to evacuate.

The plane, on route from Denver to Los Angeles International Airport, “reported striking a pedestrian during takeoff at DEN at approximately 11:19 p.m. on Friday," the airport's official X account wrote.

A spokesperson for the airport said the pedestrian, who jumped a perimeter fence, has died. They said the unidentified person was hit two minutes after entering the airport. The person is not believed to be an airport employee.

“We're stopping on the runway,” the pilot tells the control tower according to the site ATC.com. “We just hit somebody. We have an engine fire.”

The pilot tells the air traffic controller they have “231 souls” on board and that an “individual was walking across the runway.”

The air traffic controller responds that they are “rolling the trucks now" before the pilot tells the tower they “have smoke in the aircraft. We are going to evacuate on the runway.”

Frontier Airlines said in a statement flight 4345 was the one involved in the collision and that “smoke was reported in the cabin and the pilots aborted takeoff.” It was not clear whether the smoke was linked to the crash with the pedestrian.

“The Airbus A321 was carrying 224 passengers and seven crew members,” the airline said. “We are investigating this incident and gathering more information in coordination with the airport and other safety authorities.”

Passengers were then evacuated via slides and the emergency crew bused them to the terminal. The airport spokesperson said 12 passengers suffered minor injuries and five were taken to local hospitals.

Denver Airport said the National Transportation Safety Board had been notified and that runway 17L, where the incident took place, will remain closed while an investigation is conducted. It is expected to open later today.

The pedestrian death came a day after a Delta Air Lines employee was killed while on the job at the Orlando International Airport. In a statement, the airline said the employee was killed Thursday night without providing details of the incident nor the name of the employee.

“We are focused on extending our full support to family and taking care of our Orlando team during this difficult time,” the airline said. "We are working with local authorities as a full investigation gets underway to determine what occurred.”
