(Portland, OR)  --  A proposed pipeline terminal is closer to making its way to Portland, despite protests from hundreds of demonstrators.  The city's Planning and Sustainability Commission has voted to amend a zoning code in order to allow the Pembina Pipeline terminal.  Demonstrators gathered yesterday outside the commission's public hearing to rally against the pipeline.  Pembina, which is based in Canada, is hoping to bring 37-thousand barrels of propane via pipeline through the Port of Portland, have it stored here, then transfer it by ship to Asia.
