Tyler County Emergency Management Coordinator Dale Freeman says just under 20,000 gallons of oil have spilled into Otter Creek off County Road 2590. Tyler County officials were alerted to the spill Saturday by residents who noticed the oil in Otter creek.
Otter Creek feeds Russell Creek and Russell feeds the Neches River.
Oil has spread into Russell Creek, but Freeman believes the leak was discovered before any oil could reach the Neches.
The pipeline is owned by Sunoco Logistics and the company says the leak has been patched up and oil is no longer flowing through the pipeline.
Sunoco sent a statement to 12News via email saying "We will perform a thorough investigation into the cause of the incident. Right now, our priorities are the safety of the community, our employees and contractors, and the protection and restoration of the environment."
The Environmental Protection Agency and the Texas Commission on Environmental Quality are helping with the clean up. Crews have been ordered to work around the clock until it is complete.
