Narrative
Investigation of the incident remains ongoing. The affected right-of-way contains a third-party pipeline, which also transports refined products. Sampling data of the impacted soils appears inconsistent with a release of product from empco's pipeline. It is unclear at this point whether the subject pinhole anomaly was through-wall prior to sandblasting and cleaning for examination. At this point, it appears the release impacted mainly soil, but intermittent light sheens were observed on an apparent man-made impoundment on santa clara creek, guadalupe county, texas. The pipeline was shut down at 06:15 9/24/14 in the course of normal business. The release was discovered at approximately 10:00 9/24/14. The pipeline was repaired utilizing a full encirclement welded sleeve.
