Text For Citation: 01 Item/Group: 006 Hazard: REFINERY

29 CFR 1910.119(e)(1): The process hazard analysis is not appropriate to the complexity of the process and does not identify, evaluate, and address the control of the hazards involved in the process: (a)This violation occurred on or about January 27, 2009, and times prior thereto, where the employer's process hazard analysis's conducted in 1994,1999 and 2009 for the LPG Storage Tank 201 (installed on July 1990) did not address whether or not the pressure relief valve vented to a safe location. The employer did not conduct a plume dispersion model or calculations of the worst case flammable vapor cloud scenario to determine if the pressure relief valve on the LPG Storage Tank 201 vented to a safe location. The LPG Tank has a maximum capacity of 72,700 gallons (water capacity) with a pressure relief valve located on the top of the pressure vessel. A parking area, abandoned administrative building and operators break room is within 236 feet of the LPG storage tank. This condition exposed employees to a fire and explosion hazard. Pursuant to 29 CFR 1903.19(d), within 10 calendar days of the date of this citation, the employer must submit documentation showing that it is in compliance with the standard, including describing the steps it is taking to ensure that LPG Tank 201 vents to a safe location and how this information will be included in the PHA.
