Oregon’s Land Use Board of Appeals on Wednesday rejected Portland’s limits on the expansion of fossil fuel infrastructure in the city, saying the ordinance violated the commerce clause of the U.S. Constitution. The ordinance was passed last December and was the signature legacy of Portland Mayor Charlie Hales. The ordinance was born after the city decided against making zoning changes to accommodate a $500 million propane export terminal proposed by a Canadian energy company, Pembina Pipeline Corp., at the Port of Portland’s Terminal 6. Hales originally supported that project, but reversed course after a groundswell of public opposition that focused on the public safety, environmental and climate change impacts of large fossil fuel facilities. The Portland Business Alliance joined fuel suppliers to appeal to the state Land Use Board of Appeals.
