This photo, taken from Van Nuys City Hall, 8th floor, looking northeast, shows the Valley steam plant in Sun Valley, at left, on January 31, 1955. The haze from the stack is caused when the burners are changed from gas to oil. Management says the operation is well under the maximum permitted by the Smog Control district, according to William Mason, project engineer. He said that "some smog does escape when we burn oil instead of gas. This change is necessary when the gas supply is too low." However, more than $4,000,000 is being invested in smog prevention devices at the plant.
