DEER PARK, Texas — For many, it's a sight they are used to. For others, it can be alarming at first.
No emergency action was in place, but the night sky was glowing around the Shell Deer Park plant southeast of Houston overnight.
Some viewers as far away as I-10 and the 610 West Loop reported being able to see the glow.
Early Tuesday morning, the plant was conducing flaring. Flare stacks are used to burn off chemicals to relieve pressure in the facility, sometimes caused by power outages.
This time around the plant said the flaring was caused by "work activities."
Shell Deer Park posted the following message to its Facebook page:
"We are performing work activities that may cause flaring. We are taking steps to minimize any noise, light, or smoke associated with this flaring activity. There is no threat to the community or our industry neighbors. We apologize for any inconvenience our flaring activity might cause our neighbors."
