NORTH CHARLESTON – The state agency that owns and operates the Port of Charleston is temporarily halting operations at its underutilized Leatherman Terminal here to save money in the face of a global trade slowdown. The S.C. State Ports Authority said on Thursday that the container terminal's shutdown will be complete by Aug. 1 and will continue for an undetermined period. Currently, five Mediterranean Shipping Co. vessels make weekly calls at Leatherman.
