Odor Nuisance Determination
On Aug. 15, 2018, DEQ issued Daimler a notice of suspected odor nuisance
. The notice provides Daimler the opportunity to enter into a Best Work Practices Agreement with DEQ to reduce odors from the facility. If Daimler does not agree to reduce odors, DEQ will pursue enforcement. Daimler has 20 days to respond to DEQ.
This decision is based on data gathered over a five-year period, including data from DEQ's air monitoring stations, DEQ odor studies, and information from DEQ's complaints system, as well as odor data collected by the University of Portland and submitted to DEQ.
