As we repair our Crude Unit, we are providing these periodic updates to keep you informed about important issues, updates and progress.

We are moving forward with the permitted repair work to our refinery’s Crude Unit, which was damaged in the August 6th fire, and look forward to returning it to full operation with enhanced safety and reliability early next year.

Last week, we submitted a detailed report on repairs to the Crude Unit to the Bay Area Air Quality Management District (BAAQMD) and the City of Richmond. As outlined in the letter, all repairs and replacement equipment and materials for the damaged portion of the Crude Unit will meet or exceed applicable industry standards and codes. The steps we are taking will upgrade certain components of the Crude Unit, enhance our inspection processes and reduce potential sources for emissions. There will be no change in use or increase in throughput from these repairs.

As we work through this repair methodically and diligently, Chevron is doing so in a way that will further enhance our refinery’s overall safety, reliability and environmental performance.

Operational excellence is at the center of everything we do and our commitment to minimizing our impact on the environment is widely recognized. We work with more than 30 federal, state and local regulatory agencies to ensure that the refinery meets or exceeds stringent environmental standards for air, water and waste. For example:

• We have reduced Crude Unit NOx emissions by 95% since the late 1970s.
• At the Crude Unit, energy efficiency upgrades over the last five years have resulted in the reduction of over 12,000 Metric Tonnes per year of greenhouse gas emissions.
• Our Flare Minimization Plan has led to an 87% reduction in sulfur dioxide from flaring events from the 2004-2007 average.
• We are consistently ranked among the best West Coast refineries (1st in 2008 and 2nd in 2010) in energy efficiency.
• Over 60% of the water we use is reclaimed water. With a recent partnership between Chevron and the East Bay Municipal Utility District to purify and use reclaimed water, enough fresh water is freed up to supply 16,000 homes (46,000 people).

The Richmond Refinery is an important contributor to meeting the energy demands of Northern California. We look forward to returning the refinery to full production so it can provide the product and economic benefits that are so vital to the local and regional economy.

We will keep you updated about the status of our Crude Unit repairs and look forward to continuing to hear from you in the future.
