Narrative
On 7/24/2015 at 14:15 a contract crew damaged a buried tubing line during excavation near the line 02 unit 5 discharge valve inside houston station. The 3/8 inch armor-coated tubing was connected to unit 5 case pressure instrumentation. The tubing was struck by a mini excavator and pulled apart, releasing 80 gallons of diesel fuel before it was isolated. Internal notifications were made and a technician and contractor crew working at the site immediately started clean up and repair activities. Temporary repairs were completed by 15:00 and the line was restarted at 15:20. Final cleanup efforts were completed by 18:50. All released product was contained on company property in the immediate area. No immediate state, local or federal agency notifications were required due to the volume released and that it was contained on company property. A post-accident drug and alcohol test was conducted on the contract operator of the mini excavator.
