// Strategic Significance
Chevron Richmond is the largest refinery on the West Coast processing 240,000 barrels per day. The August 6 2012 refinery fire sent a toxic plume over Richmond causing 15,000 residents to seek medical treatment in one of the worst US refinery accidents of the decade. The refinery sits in a densely populated urban area with serious earthquake and fire risk.
// Civilian Impact Assessment
Richmond with 116,000 residents surrounds the refinery. The 2012 fire sent 15,000 people to hospitals. The urban location means any major accident directly affects dense residential neighborhoods. Hayward Fault earthquake risk creates compound industrial hazmat scenario.
