Paraco has three spots for LPG tank car unloading on their siding; located at 44 Kroemer Ave., Riverhead. The eight white tanks have a capacity of 30,000 gallons of propane, but are not filled all the way to allow for expansion. I was told they are filled with about 28,000 gallons. Info: Steve Rothaug
Steve: Thanks for the overhead photo. It is interesting and can answer jhdeasy's question.
@jhdeasy: From the photo, I would say each tank can hold 30,000 gallons. The tank cars in the photo look to be cars for liquid propane service. Their capacities vary but a standard is 33,000 gallons apiece. They appear to be about the same size of each storage tank.
