Text For Citation: 01 Item/Group: 011 Hazard: REFINERY

29 CFR 1910.119(d)(3)(ii): The employer did not document that equipment complies with recognized and generally accepted good engineering practices (RAGAGEP): The employer does not ensure that process safety information pertaining to the equipment in the process contains documentation that all equipment complies with RAGAGEP. The conditions were observed, as noted in (a) through (c) below, on or about February 4, 2009, and at times prior to and thereafter, at the Sinclair Tulsa Refinery. a) In the CDU: The employer does not document that the FA-24 knockout drum vent stack complies with RAGAGEP where it does not determine vent stack height is appropriate according to radiant heat levels; does not determine mitigation measures for hazards other than vapor cloud explosion such as exposure to H2S; and does not ensure prevention of flashback by using a purging media other than steam. The FA-24 vent stack is not compliant with RAGAGEP such as API 521, Pressure-relieving and Depressuring Systems. b) In the FCCU: The new control building housing multiple refinery units (Scanfiner/FCCU/Alky) was designed for blast overpressures; however, the employer has not documented its compliance regarding the control room's role as a safe haven during emergency releases of flammable or toxic materials. The positive pressure control system lacks system equipment such as hydrocarbon or toxic (hydrogen sulfide) detectors to shut down the intake of contaminated air. The control room is not compliant with RAGAGEP such as API 752 Management of Hazards Associated with Location of Process Plant Buildings. c) In the FCCU: The employer does not document that atmospheric releases from relief system equipment, such as, relief valves on the E-1 Fractionator (309, 312, 358, 359, 2077, 2078, 2079, 2281, 2283, 2861), E-5 Splitter (2763, 2764), F-4 Fractionator Reflux Drum (2781, 2782), F-11 Debutanizer Reflux Drum (2765, 2766), F-12 Splitter Reflux Drum (2768, 2769) are discharged to safe locations in compliance with RAGAGEP such as API 521. Pursuant to 29 CFR 1903.19, within ten (10) calendar days of the date of this citation, the employer must submit an abatement plan describing the actions it is taking to ensure equipment in the process is compliant with RAGAGEP.
