1. CASE STUDY EXAMPLE Work Process Flow Charts

2. WORK IDENTIFICATION / WORK ORDER PROCESSING Review Notification Asset Coordinator Notification complete and accurate? Work request needed? If not, send back to Identifier SAP EZ-notification Enter Notification Shift Supervisor / Designee Hang Work ID Tag Maintenance Coordinator/Designee Routine? Capital work? TAR? If not Routine, give feedback to Identifier Determine How It Will Be Worked Asset Coordinator Determine if it will be worked under blanket MO Asset Coordinator Reference Blanket Order Policy (EBB) Operator Performs Maintenance If not, record all relevant information for quality notification input Can Operator Perform Work? Shift Supervisor Shift supervisor responsible for declaring Emergency/Urgent status Troubleshoot with team Determine if work is required Determine Urgency Shift Supervisor Operator Performs Maintenance Operator performs Maintenance if possible If not, go to next step Operator Investigate Problem Gather problem information then contact supervisor What is the problem/opportunity? Where is it (asset location/identifier)? When does it occur (related process operation, etc.)? How much is it occurring (minor vibration, large rate of drip, leak, break, etc.)? How often (all the time, sometimes, rarely)? Note: If it is suspected an Emergency condition, go directly to next step Identifier Identify Work Everyone is responsible to ID work (early) Early work ID is safer and less costly Everyone Hang ID Tag as close to the problem area as possible

3. Notification in SAP Planner reviews new approved notifications in SAP. Assures job description is adequate. Create M.O. with planner group 0 Minimum 2-3 days prior to allow for detailed planning. Planner ROUTINE MAINTENANCE WORK PLANNING PROCESS Field Scope Job Planner visits work site to assemble information for plan. Materials, tools, equipment, and craft resources needed Supervisors/Job Reps may also be asked to review job Safety requirements must be observed Planner/Supervisor Planner works with Supervisor to determine job note need The Planner contacts the Unit Maintenance Engineer to create job note if needed. Job Note Request Planner/Supervisor/UME Search SAP database to find existing job template if available. Plan as new if not available The Planner copies the template into the new maintenance order The maintenance order can be updated with additional details, job steps, etc. Update status to planner group 1 Plan The Job Planner The Planner enters detailed tasks into SAP with correct work centers Work centers are used in SAP to determine what crafts will work each task Multiple tasks are entered for operators as well as crafts Craft Assignments Entered Into SAP Planner Determine Who Will Perform Job Planner/Supervisor Non-core work is tasked to contractor The Planner and Supervisor determine if contractors will be needed to perform the work The Planner enters stock and non-stock materials into the plan Procurement Coordinators are asked to help procure materials when needed Planner will use the VAM (Vendor Agreement Management) tool when buying non-stock items Materials, Tools, Equipment Into SAP Planner The Planner will determine if the work is budgeted before releasing the order for work. If the work is Not in the budget, a variance will need to be created and approved. Release material requisitions. Event Based Budget Review QA/QC Requirements Identified Unit inspectors are notified when work will be performed The Planner will include steps for inspection and quality control in the estimate Planner/Unit Inspector The Planner will initiate permits for all tasks on the order that require one The Planner will contact the correct Maint. Supv. / Job Rep. to begin the risk assessment Appropriate level of risk assessment and permit creation occurs Detailed Job Package Assembled Planner Minimum Job Plan Requirements - Complete SAP printed M.O. - Primary & secondary crafts - Labor estimates - Description of job steps - Status of materials & locations - QA/QC requirements - Repair specifications - Location of work Maintain ready to schedule file Update status to planner group 2 Permit is Initiated Planner/Maint. Supv/Job Rep

4. ROUTINE MAINTENANCE WORK - DAILY SCHEDULING PROCESS Update Current Day’s Schedule Planner reviews current day schedule with completed work and work that will carry over to the next day Updates are made in the current tools Planner Preparation for Unit Daily Scheduling Meeting Scheduler, Maintenance Supervisor, and Planner provide the Asset Coord. with MO status information in preparation for the Unit Daily Scheduling Meeting Scheduler Mandatory attendees: Asset Coordinator (Team Leader), Maintenance Supervisor, Planner, Maintenance Coordinator, Operations Supervisor Attendees as appropriate: Unit Engineer, Inspections, Capital Project Reps, Job Rep’s etc. Conduct Unit Daily Scheduling Meeting Planner, Supervisor, Asset Coordinator Address Resource Issues Planner Planner contacts Maintenance Supervisor to support manpower requirements Planner contacts scheduler to make necessary changes. For break-in-work, EBB and financial controls requirements, resource availability (materials, manpower, and rentals), this must be fulfilled prior to adding jobs to the daily schedule Scheduler reruns schedule for deviations (additions / deletions) Address Schedule Deviations Scheduler Scheduler runs final schedule for approved work The Planner updates the backlog per final resource decision Run Final Schedule And Update Backlog Scheduler, Planner Scheduler sends email notice of schedule availability to site teams Notification of Schedule Availability Scheduler Operations and Maintenance Supv./Job Rep. verify permit readiness by reviewing risk assessment, initiated ATW and associated permits Permit Creation Operations / Maint, Supervisor / Job Rep.

5. Ready to Work Backlog Planner sends a copy of the RTW backlog to the unit team members Planner WEEKLY WORK SCHEDULING PROCESS Finalize Schedule Scheduler makes changes to schedule resulting from the weekly meeting Scheduler makes schedule available on the website no later than Thursday at 4:00 pm Weekly Scheduling Meeting Select jobs for weekly schedule that meet the unit requirements for safe optimal operation Considerations for selection: LOTO Priority Equip. Availability Carry over work Critical trips & alarms PM’s Budget Backlog Updated RIME priorities Planner codes scheduled Maint. Orders in SAP by 2:30 pm Planner, Maint. Supv, Main.t Coord, Shift Supv, Asset Coord. Scheduler downloads coded Maint. Orders from SAP into P3e draft schedule Scheduler incorporates TAR, Tank TAR, infrastructure, and capital projects schedules into the P3e draft schedule Scheduler Creates Schedule Scheduler Site Wide Scheduling Meeting Planning Scheduling Supt. /Asset Coords, TAR and Routine Planning & Scheduling Leads, Shift Director, Schedulers Planning Superintendent facilitates a high level review to gain consensus on what will be worked on at a high level Attendees commit to schedules Scheduler Resource Validation & Update Scheduler levels resources noting any conflicts because of resource or CoW issues Scheduler contacts unit planner where resource restrictions are found Planner contacts asset coordinator for review Asset Coordinator prepares to discuss issues around resource allocation Scheduler, Planner, Asset Coordinator

6. ROUTINE MAINTENANCE WORK EXECUTION AND ACCEPTANCE PROCESS Operator, contractor crew rep and job rep (contractor work) sign the ATW Work Crew Rep or job rep (contractor work) or responsible operator review the Permit Pack and conducts pre-job safety review with everyone in the work crew.
