Narrative
On 9/22/2016, an operator of an agriculture field spraying rig reported to US that his spray boom struck an above-ground blowdown riser, at a main line valve location, and caused CO2 to be released into the atmosphere. The spray rig operator was instructed to leave the immediate area and move to a designated area to wait for chaparral midstream personnel to arrive. Chaparral midstream personnel arrived at the affected valve site location, confirmed the existence of a CO2 leak immediately downstream of mlv 1 , and secured the area. The release did not result in explosion, fire, death, personal injury, significant property damage, or pollution of any water body, and was confined to chaparral property at the valve location. The damaged blowdown riser was isolated by closing the upstream and downstream valves, and that isolated segment was then blown down using the blowdown riser at mlv 2. The damaged blowdown riser was repaired by replacing the flange and connection. X-ray of all welds on the replacement joint was accepted. Later that same day, the air in the affected segment was purged with CO2, and was returned to service in a safe manner without incident.
