Looking back, Delaware River Stevedores pulled out of Southport because "the initial cost estimates of doing the terminal were hundreds of millions of dollars," said DRS president Robert Palaima, the operator of Tioga terminal. "It's a great location, but a site that required a lot of fill. Economically, it was hard to put more than two berths there just because of the geology. You'd need pretty good throughput to spend upwards of $300 million. For private money, you had to be dead certain you had strong commitments from customers to do that," Palaima said.
