The American Society of Agricultural and Biological Engineers, has initiated a revision to ASAE EP379.3, Control of Manure Odors.  

A committee will focus on the separation distances currently included Section 6.2.1. Feedback from users of the standard has suggested elimination of specific stated separation distances. Instead, users would prefer research-based computer modules that include various physical and chemical considerations as well as the number and type of animal operation.

If you are interested in becoming involved with the revision of the separation distance standard, contact Scott Cedarquist at ASABE, 269-429-0300, cedarq@asabe.org.
