Document Description
The proposed Project will replace the existing fuel tank located at the ISD Oat Mountain Microwave Station inside the Southern California Gas Company Aliso Canyon facility. The above-ground tank, which has reached the end of its service life, provides fuel to the emergency generator in the event of a loss of commercial power. The microwave station is key to County communications, and a new fire-rated fuel tank would help to ensure the continued site operation in the event of the loss of commercial power.
