Text For Citation: 01 Item/Group: 005 Hazard: REFINERY

29 CFR 1910.119(d)(3)(ii): The employer does not document that the equipment in the process complied with recognized and generally accepted good engineering practices: (a) This violation occurred on or about January 27, 2009, and times prior thereto,where the employer did not comply with RAGAGEP (i.e. API 521 Sec. 4.3, 4.4, 4.5) when it failed to evaluate (e.g., calculations and/or plume dispersion model modeling) whether releases from relief system equipment discharged to safe locations. The worst case flammable vapor cloud scenario was not evaluated 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, operator's break room, and operator's control room are 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. (b) This violation occurred on or about January 27, 2009, and times prior thereto, where the employer located its steam discharge for the pressure relief valve of steam line E-D- 2-118 eight inches from an employee work area. The discharge point was approximately four feet above the work location and plant steam is 135 Pounds. If the pressure relief valve functioned as designed scalding steam could be released into the employees work areas. Employees could suffer burns from the discharging steam plume. This condition exposed employees to the hazard of burns from steam. 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 the pressure relief valve from steam discharge line E-D-2-118 does not discharge into an employee work area.
