By Steve Early for Counter Punch - Five years ago, my wife and I moved to Richmond, CA and soon learned about the local emergency response protocol known as “shelter in place.” When large fires break out in Bay Area refineries, like the century old Chevron facility near our house, first a siren sounds. Then public officials direct everyone nearby to take cover inside. Doors must be closed, windows taped shut, if possible, and air conditioning turned off. August 6th is the fifth anniversary of such self-help efforts in Richmond. On that day in 2012, we looked up and saw an eruption worthy of Mount Vesuvius. Due to pipe corrosion and lax maintenance practices, a Chevron processing unit sprang a leak. The escaping petroleum vapor reached an ignition source. This led to a raging fire that Contra Costa County (home to four refineries) classified as a “Level 3 incident,” posing the highest level of danger. Nineteen oil workers narrowly escaped death at the scene of the accident. It sent a towering plume of toxic smoke over much of the East Bay and fifteen thousand refinery neighbors in search of medical attention for respiratory complaints, While local property values took a hit, Chevron stayed on track to make $25 billion in profits that year.
