Nuisance odor strategy

State laws prohibit businesses from emitting odors which cause a nuisance. DEQ is responsible for implementing those laws. To help us in that effort, DEQ has developed a strategy for responding to odor complaints.
The strategy emphasizes early odor detection, voluntary cooperation and the rapid resolution of nuisance conditions related to odors. The Nuisance Odor Strategy Report describes the strategy.
