Take a stroll, or bike ride, or drive by the Zenith Energy Portland Terminal, 5501 NW Front Ave. Notice the smell, the poor air quality. Maybe it's making you cough, or feel sick? Then, contact the DEQ and file an “Odor Complaint”. https://www.oregon.gov/deq/aq/Pages/Nuisance-Odor.aspx
Let them know of your displeasure.
Zenith sucks. We all know it. The DEQ knows it. Even Zenith's executives probably know it. But imagine what it is like to live near that. Or to work at the site. We need to remind the folks with the power to do something.
