When they first showed the location of the tanks, I did a little research and found diagrams of similar sized crude oil tanks outlining the features and measurements. I don’t know for sure if the tanks were exactly the same size, but the manhole measurements were 18”-21”.
Is the 18-21 number the diameter or the circumference? Because some said the tanks had 8 inch diameter which is a 25 inch circumference.
