Lessons Learned Opportunities for improvement broken down and summarized in 4 categories –Process Improvement – Information Management and Direction –Organization – Design and Integration –Infrastructure – Facilities and Technology –Training and Skills - Functional Capability

Lessons Learned Process Improvements –Use phased ramp-up of crisis management team based on situation –Develop and follow robust documentation process –Develop and use an action item tracking process –Assure situation briefing are given to all involved people –Stay in process

Lessons Learned Organization –Integrate all levels of response into a single organization (One Plan) –Train personnel on different roles and responsibilities –Drill the emergency response organization

Lessons Learned Infrastructure –Identify remote operations centers in advance of event –Improve availability of emergency response plans in EOC –Develop and communicate response objectives to entire team quickly –Utilize networked software to provide equal access to all information by all team members –Develop and implement de-mob checklists for emergency response teams

Lessons Learned Training and Skills –Provide training on software used to capture and manage information –Train business units on setting objectives and directing the team –Keep training content current and provide in a timely manner.

Upstream

Upstream Actions Hurricane Preparation and Evacuation procedures updated based on hurricane experience Performance study conducted on Gulf of Mexico Magnolia Platform Equipment modification completed on Magnolia Platform Each new Louisiana inland water platform design is now evaluated from a risk/benefit basis to build at a height equal to the 100 year flood level

Magnolia Platform The Magnolia field was discovered in 1999 (1 st production 2004) and is located 165 miles south of the Louisiana coastline in Garden Banks blocks 783 and 784. Magnolia is located in almost 4,700 feet of water. Magnolia had no major equipment failures – and that was in spite of Hurricane Rita’s eye wall passing within 25 miles of the facility.

Equipment Changes on Magnolia Platform Gulf of Mexico platforms have installed storm latches to all doors to prevent doors being blown open resulting in water/wind damage to the interior. Also installed wind diffusers for the Auxiliary Generators to prevent overheating & shutdowns caused by hurricane force winds.

Magnolia Platform Performance Study Study conducted by an external engineering group (Houston Offshore Engineering) Study assumed Magnolia Platform exposed to a direct hit by a “Rita” type hurricane Conclusion of the study was that even though environmental conditions were significantly higher than design criteria Platform would withstand storm without loss of integrity –No over tensions of tendons –No periods of tendons going slack Highest wave crest would be one foot below bottom of deck

Downstream Actions Conduct annual hurricane plan drills before season commences Conduct audits during season to verify level of preparedness Setup dedicated employee storm communication hotline Load hurricane plans in Incident Action Plan software (same as used by IMAT) Identify, dedicate on site response equipment for use at any of the Gulf Coast facilities Remove critical electric motors prior to storm

Gulf Coast Recovery Equipment Plan Gulf Coast recovery equipment identified at the end of 1 st quarter Identified recovery equipment is procured in 2 nd quarter Equipment will be housed and maintained at Sweeny Refinery Transportation is charged with moving equipment Permits to allow transport of equipment will be filed prior to storm Proper equipment to unload portable equipment at site will be identified One hurricane plan coordinator will be designated for Gulf Coast region

Refinery Specific Actions Lake Charles Refinery Upgrade overhead electrical system in tank farm area (5 year plan) Evaluating options to reduce water intrusion in selected sub stations. Sweeny Refinery Manage hurricane response equipment for the Gulf Coast area Pursuing agreements with local maintenance contractor to provide housing repair assistance

Refinery Specific Actions Alliance Refinery Operations Control and Maintenance Field Office buildings upgraded to withstand 200 MPH winds Mississippi River levee evaluated –Corp of Engineers allow a levee height of 16 feet and will not permit any height increases –Height of levee at 2 points of washout during Katrina were 14 feet in height due to pipe way crossing –Discussions underway with the Corp to allow increase in height to 16 feet Project approved to increase water pump off capability All future motor control centers and instrument buildings will be elevated to protect from rising water Instrument upgrade project is open architecture which allows easy replacement in the event of damage Decision and Risk Analysis currently underway to develop best protection scenario for the refinery
