Narrative
The landowner (mr. Danny spencer) was conducting grading activities across a drainage ditch on his property, when he struck an active m6 midstream llc, natural gas gathering pipeline. The excavation activities resulted in a puncture of the affected gathering pipeline and resulted in natural gas and associated condensate/produced water to be released to the atmosphere and surrounding area. Due to mr. Spencer's grading activities, there was no way to know the depth of the pipe prior to the excavation. There was a pipeline sign near the area that appeared to have been removed from the row, approximately 300 feet from the line strike. The affected pipeline was isolated and blown down and the damaged section has been removed from service.
