Narrative
At approximately 7:30 on 5/10/2018 oneok field representative was contacted by contract crew working at oenok's new fall creek junction site to report vapors coming from a 1/2" pipe nipple on a double block and bleed valve on the meter skid. Oneok representative arrived on site at approximately 8:00 am and isolated the valve and removed and replaced the failed pipe nipple. An elevated access platform had been installed prior to heavy rain in the area and as a result of the rainfall, settled in the dirt, allowing the side of the platform to contact the pipe nipple on the double block and bleed valve which caused the nipple to crack causing the release of hydrocarbons. The platform was modified and relocated to prevent a repeat of this type of accident.
