Narrative
Operator personnel discovered product pooling in the concrete pig barrel containment at approximately 12:01 am. At the time, it was believed approximately 1 gallon of product was released. Following further investigation, it was determined at 6:45 am that approximately 2 bbls of product had been released into the containment pad and onto the surrounding gravel. A newly-installed thermal relief valve on the p91 pig barrel had leaked-by, allowing product into a shared drain system. The drain system was blocked by blasting media from a recent painting project and backed up into the pig barrel containment. The relief was isolated and repaired, product cleaned up, and the drain line cleared and verified open.
