Narrative
At approximately 9:15 pm on saturday 10/29/2016 mov 3400 on the wcii pump #2(p-3352) had an un-commanded closure. The controller on duty commanded the valve open at 9:21 pm and the valve was fully opened by 9:22 pm. Shortly after reporting to duty, the day controller noticed an imbalance on the over/short for wcii pipeline. The controller contacted the control center manager at 6:45 am and it was decided to shut wcii pipeline down. By 7:00 am shutdown was complete. The leak was confirmed at 7:38 am by roger pfeifer, a company employee who was conducting his daily station check. Roger contacted the control center at 7:38 am to lockout pump #2 (p-3352). All internal,state and federal agencies were notified and acme environmental, osro, was contacted to muster personnel and equipment to the site. It was determined by pipeline over & short analysis that approximately 1,722 bbls of dj basin derived crude oil was released to the environment from an outboard seal failure on pump 2 (p-3352) at sharon springs station. Less than 20 bbls of free oil were recovered at the site. Crude oil was released to soil in ne portion of the station, along highway 27 kdot row east of the station fence and approximately 500 feet north of the station fence in two streams. One stream was approximately 510 feet in length on the mills property and the other stream was approximately 350 feet long on the highway 27 kdot row. The environmental cleanup, as approved by the kdhe, consisted of a large scale dig and haul operation that removed approximately 14,000 cubic yards of impacted soil. The mills property and kdot row was cleaned up to residential standards. Company property is being cleaned up to non-residential standards. Excavated soil has been transported to the hanson ranch for land farming under the approval and authorization of the kdhe. Proposed action plan: 1. Modify the pump control program (system wide) as follows: a) add the missing sequence start command contact. B) add an unintended suction valve closure shutdown. 2. Remove the "sequence start" command from scada until programing changes are made system wide. 3, add a redundant seal leak detection system that will detect pressure (system wide). 4. Install fully enclosed seal covers (system wide). 5. Add a valve closure discrete bit and updated the control center alarm dictionary (system wide). This includes training of the control center operators. 6 clean up continues at the station with approximately 98% recovery. The final total contaminated soil removed was 14,474 yards.
