The second draft of the BREF (Best Available Techniques (BAT) Reference Document ) on Intensive Rearing of Poultry and Pigs (IRPP) has been issued on 01/08/2013 and the word "odour" appears 487 times. This is a measure of the importance of the odour management in this BREF. For example, in the recently reviewed and final Draft of the BREF Document for the Production of Pulp, Paper and Board, the word odours appears 148 times. 

   This is a good opportunity to revise the Draft and send some comments concerning the odour management field, for those of you who are involved in odour regulations. Surprisingly, there is no "odour unit" reference in the final draft of the BREF on the Production of Pulp, Paper and Board ⁽¹⁾, therefore there is just a tangential treatment of one of the major problems of these activities.

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.
