Narrative
On 4/10/2016, a land owner reported to US a smoke-like substance emanating from the ground near our buried texok CO2 pipeline. Operator personnel located and confirmed the existence of a CO2 leak and observed some dry ice over the row that was sublimating into a gaseous state. The area surrounding the leak was secured and the release did not result in explosion, fire, death, personal injury, significant property damage, or pollution of any water body, and was confined to the pipeline right of way. The CO2 source plant was notified and shutdown, and the leaking pipeline segment was isolated by closing the upstream and downstream valves. On 4/11/2016, the affected segment was blown down by opening above-ground blowdown valves near the upstream and downstream valves. Upon excavation on 4/11/2016, three dime-sized areas of missing coating were observed on the fbe-coated pipe that was installed in 2010. Also, a small crack two inches in length was found along the longitudinal seam of the pipe, starting about three inches away from a girth weld. The entire pipe joint containing the missing coating areas and the crack was cutout and removed, and was replaced with pre-tested pipe. X-ray of both welds on the replacement joint was accepted. On 4/13/2016, the pipeline was purged with CO2 by opening the upstream valve. Once purging was completed, valves were opened and the CO2 source plant was restarted, returning the pipeline to regular service in a safe manner. The dig hole was backfilled without incident.
