29 CFR 1910.119(d)(3)(i)[B] Information pertaining to the equipment in the process shall include: Piping and instrument diagrams (P&ID's); A. The employer did not ensure that information pertaining to equipment in the process, specifically piping and instrument diagrams (P&ID's), was complete and accurate. This violation was identified during inspections of the facility from November 2009 to March 2010, Silver Eagle Refining Inc., 2355 South 110 West, Woods Cross, UT, 84087. On 11/19/2009, P&ID Drawings for all Process Units were requested. The employer responded by providing: i.P&IDs 03-PR-PID-0001 thru 03-PR-PID-0026 for the MDDW Unit (MDDW CSB 1DOCC4.3. 0143 thru MDDW CSB 1DOCC4.3. 0167), and ii.P&IDs 01-PR-PID-0001 thru 01-PR-PID-0031 for the #1 Crude Unit (MDDW 1- UOSH21 0001 thru MDDW 1-UOSH21 0026), and iii.P&IDs 02-PR-PID-0001 thru 02-PR-PID-0018 for the #2 Crude Unit (MDDW 1- UOSH21 0027 thru MDDW 1-UOSH21 0043), and iv.P&IDs 05-PR-PID-0001 thru 05-PR-PID-0040 for the Reformer Unit (MDDW 1- UOSH 0044 thru MDDW 1-UOSH21 0076). Documents provided as 1-UOSH-21 did not include a legend explaining all symbols used to represent valves, controls, piping fittings, etc. By not identifying current symbols on the P&ID's, employees may not be able to locate critical equipment in the field. In the event of an emergency, employees can be exposed to serious injury or death should they not be able to locate critical pieces of equipment. This may be a system-wide occurrence that requires evaluation of all piping and instrument diagrams (P&ID's) throughout the facility.

The employer did not ensure that information pertaining to equipment in the process, specifically piping and instrument diagrams (P&ID's), was complete and accurate. This violation was identified during inspections of the facility from November 2009 to March 2010, Silver Eagle Refining Inc., 2355 South 110 West, Woods Cross, UT, 84087. While performing field verifications, an isolation valve just downstream of PSV 39425 in the MDDW Unit was not symbolically represented on Drawing No.: 03-PR-PID-0004, (MDDW CSB 1DOC4.3 0146). In addition, the P&ID did not state that this valve was to be car- sealed open as it was downstream of a PSV that did not relieve to the atmosphere. By not maintaining complete and accurate P&ID's, in the event of an emergency, employees can be exposed to serious injury or death should they not be able to locate critical pieces of equipment. This may be a system-wide occurrence that requires evaluation of all piping and instrument diagrams (P&ID's) throughout the facility.

The employer did not ensure that information pertaining to equipment in the process, specifically piping and instrument diagrams (P&ID's), was complete and accurate. This violation was identified during inspections of the facility from November 2009 to March 2010, Silver Eagle Refining Inc., 2355 South 110 West, Woods Cross, UT, 84087. While performing field verifications, an isolation valve (#36092) and a check valve (#36093) upstream of PSV 39425 in the MDDW Unit were found that were symbolically misrepresented on Drawing No. 03-PR-PID-0004, (MDDW CSB 1DOC4.3 0146). The schematic configuration on the P&ID showed the gate valve upstream of the check valve. The actual arrangement was the gate valve was downstream of the check valve. By not maintaining complete and accurate P&ID's, in the event of an emergency, employees can be exposed to serious injury or death should they not be able to locate critical pieces of equipment. This may be a system-wide occurrence that requires evaluation of all piping and instrument diagrams (P&ID's) throughout the facility.
