The Air Quality Division of the Department of Environmental Quality (DEQ) of the State of Oregon has recently released a proposal for an Odor Nuisance Strategy Report. and is asking for feedback about it. This proposal is based on several parameters, the so-called "Nuisance Factors" which are the tools used by the Environmental officers to deal with odor complaints.
DEQ last updated its nuisance rules as part of a process improvement effort in 2001. At this time DEQ is proposing a strategy to implement the existing rules. The Oregon Administrative rule on nuisance (OAR 340-208-0310) (Appendix A) describes multiple factors for DEQ to consider when determining if a nuisance exists.
