§ 54.48 ODOR MITIGATION.
   (A)    The use of odor modeling to analyze feedlot odors and make recommendations for odor management may be necessary for an expansion or modification of an existing animal feedlot pursuant to § 54.46(D)(2), a CUP, or variance request. For the purpose of this section, measuring for an odor rating shall be achieved by using OFFSET -- or another feedlot odor measuring tool recommended by the University of Minnesota and approved by the County Feedlot Officer.  
   (B)   New liquid manure storage facilities, for swine feedlots over 300 animal units, shall not be constructed unless the facility will be covered, with an approved cover, for the purpose of odor mitigation. The cover shall be in place and maintained from May 1 through November 1.
   (C)   New barns, including modifications of barns, with shallow or deep pits, must be constructed using approved biofiltration air systems, or approved equivalent (i.e., University of Minnesota approved systems).
   (D)   Feedlots requiring a liquid manure storage facility, for the purpose of pollution abatement, may be exempt from this section, if so determined by action of the Board of Commissioners.
