Imperial built a Power Plant on the east bank of Oyster Creek in 1920. It is the grey building that is still standing. (See the aerial below.) They built a new power plant on the west bank within the refinery complex in 1938, leaving the old building for other uses. One of its uses was a union hall.
The following photos were taken in the hall during May 1960 at a ceremony celebrating a National Safety Council award Imperial had won.
