9. Nuisance Odor Background • There has been ongoing public concern about permitted facility odor nuisances. • A nuisance substantially and unreasonably interferes with individual use and enjoyment of real property. • Due to increasing density and housing located near businesses, DEQ has been receiving more nuisance complaints. • State laws prohibit businesses from emitting odors that cause a nuisance. DEQ is responsible for implementing those laws. • DEQ wants a reliable and defensible way to apply our nuisance strategy rules to odor complaints related to facilities with air, water and waste permits.

Nuisance Odor Backgroundcontinued • April 2013: DEQ land, air and water team developed an improved strategy to investigate, analyze and respond to odor complaints and nuisance odor conditions. • The strategy is based on existing regulations for odor complaints from permitted facilities. • May - July 2013: DEQ gathered public input. • August 2013: DEQ incorporated input and finalized the strategy.
