Narrative
On 9/14/2020 at approximately 9:30am while conducting a DOT inspection of the10 inch mainline valve at mile marker (3.0). The main line valve's 1 inch water drain port plug was being removed to drain water when the plug abruptly disengaged the threads and 3 barrels of product was released. The operator called the supervisor and was instructed to temporarily plug the opening to stop the flow of product. The product flowed off the property onto another operator's property. No public or private property was impacted. Additional resources arrived with a new water drain plug. The new plug was installed, and the product was cleaned up. The soil was remediated on site and clean soil was brought in. In this type of valve, water dropout can collect on the bottom of the valve and is the reason for the drain plug. Over time the plug deteriorated. The valve is drained every six months along with the DOT mainline valve inspections. They will be continued to be operated and drained every six months and replaced as needed.
