PG&E Gas Control Evolution of Philosophy and Culture 11
New Control Room Training Philosophy
New Control Room Training Philosophy Golden Rules: Operate the Pipeline Safely (Know your MAOPs) Meet Minimum Pressures Make Scheduled Rates (Volumes) Operate System Efficiently
New Control Room Training Philosophy We need a training program for the operators, by the operators
New Control Room Training Philosophy Regimented Learning Objectives Gas Basics and Fundamentals Built with Operator Qualified Control Room Personnel, Engineering and Maintenance Experts Geographic-based Gas Operations System training Operational Controls Philosophy Alarm Philosophy and Management Console specific role and responsibility focused Gas system oriented training for normal, abnormal, and emergency operating conditions Certified Technical Trainers (CTT+) deliver instructor led training
New Control Room Training Philosophy Task Analysis Learning Objectives Knowledge & Skill Assessments Content
New Control Room Training Philosophy Leak Scenario Training Lessons Learned, Simulation and Hypothetical Drills Situational Awareness
A Change in Culture No Regrets! Operator Involvement Active Communication
A Change in Culture Stop the Work! Speak up culture! Field Training Boot Camp Corrective Action Program (CAP)

Scenario: L-300A Dig In incident November 13, 2015 15:32 T=0 Dig In, line rupture, MP 271 Bakersfield Tap Pressure 15:43 T=11 Remote close Bakersfield Tap MP 284. 16:10 T=38 L-300A Pressure < 50 psig. 15:42 T=10 Phone call from Bakersfield Division reporting line hit. 15:32 T=0 Dig In, line rupture, MP 271 Kern River flow PGE to SOCAL Kern River Pressure PLS-4A D/S Pressure 15:33 T=1 Kern River Station Backflow Alarm MP 281. 15:37 T=5 Kern River Station Remote Shut in Division busy closing manual valves closer to leak. 15:44 T=12 Remote close PLS-4. Kern River flow SOCAL to PGE 0.8 Hi Hi 0.1 Hi 15:33 T=1 Kern River Station Backflow Alarms Initial pressure drop rates, psi/min: MP 284 Bakersfield Tap = 12 MP 281 Kern = 50 MP 271 Rupture MP 256 PLS-4A = 9
Leak Scenario: Severe line rupture near Monroe Station 2c. College Ave flow alarm not configured. 1. Multiple SCADA Lo Lo alarms could occur: Adobe = 250 psig (one alarm) Cotati = 230 psig (one alarm) Monroe = 200 psig (4 alarms) Madrone = 230 psig (6 alarms) Santa Rosa Compressor = 195 psig (2 alarms) 2b. Nearest U/S flow meters are at Adobe: M-1 on16 L-21D Hi Hi = 2.7 MMSCFH. M-3 on l2 L-21C Hi Hi = 2.7 MMSCFH. Leak and Alarm Scenario #1 Severe line rupture near Monroe, not sure which side. 2a. The flow meter at SR compressor should indicate whether the leak is U/S or D/S of the compressor station. 3. Multiple RCV alarms occur: V-16, V-51.41, V-8 alarm at 160 psig and/or -10 psi/min. Six RCV alarms at Madrone might also be received. Alarm Alarm Alarm

Telvent SCADA System Gas Control upgraded SCADA system from Citect to Telvent based on the CFR 192.631 CRM to incorporate API 1165 Recommended Practice for Pipeline SCADA Displays. Using grayscale background, clear images for common objects and actions, and color only when necessary, the displays provide high level of situational awareness. Benefits of upgrading the SCADA systems provides a higher level of safety by providing better situational awareness and improving operational efficiency 32
