Narrative
This report details a pinhole leak discovered in a swampy/marshy area near the neches river in orange county, texas. Bubbles near a pipeline marker was reported to the operations control center. Empco employees attempted to access the area by convential boat but were unable to reach the site. Empco employees secured an airboat to and were able to locate the bubbles. The release was originally thought to be from an ethylene pipeline but was later determined to be from a propylene line. The logistics associated with getting people and equipment to the site drove the cost of the response higher than normal. Also included is the cost of flaring approximately 6.5 miles of 6 inch pipe. 5/10/16 - adjusted lat/lon, due to typo on original report
