The Oregon Department of Environmental Quality has issued Zenith Energy’s air quality permit, allowing the controversial company to continue storing and loading crude oil and renewable fuels at a hub in Northwest Portland.

State regulators issued the permit on Thursday after evaluating more than 800 written and 60 verbal comments, many of them opposing the permit. Zenith needed the permit approval to continue operations at the Critical Energy Infrastructure hub on the Willamette River.
