Port of Longview commissioners Tuesday approved the sale of $7.43 million of general tax bonds, which will pay for construction of Berth 9, the purchase of 35 acres from Simpson Timber Co. and other port projects. The bonds are being sold at a 4.7 percent fixed interest rate, about average for the port, said Kathy Oberg, finance director. Port officials say they don’t need to raise taxes to finance the bonds. The port is building the $5.1 million Berth 9 to service a $200 million grain terminal.
