29 CFR 1910.119(d)(3)(i)(D): Process safety information pertaining to the equipment in the process did not include the relief system design and design basis: The employer operates an atmospheric blowdown drum when there is incomplete original and updated design and design basis information. This violation was observed on or about February 4, 2009 in the Crude Unit, where the employer operates FA-24, an atmospheric blowdown drum, without complete original and updated design and design basis information. Pursuant to 29 CFR 1903.19, within ten (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 document original and updated design and design basis process safety information pertaining to FA-24, the Crude Unit atmospheric blowdown drum. Process safety information on the FA-24 blowdown drum must include design and design basis information such as, but not limited to, the physical and chemical properties of materials relieved to the blowdown drum, a definition of the loadings to be handled, the exit velocity of gasses/vapors released from the vent stack, design basis/worst case scenario for maximum liquid-vapor releases to the blowdown, the geographic locations of the devices and valves releasing to the blowdown, the design residence time of the vapor and liquid in the drum, the design basis for the vapor - liquid separation for the drum, the design basis for the exit velocities for the vent stack, and the nature of other, lesser hazards related to smaller releases not related to the design "worst-case" scenario such as the release of toxic (e.g., H2S) and corrosive chemicals.
