Conversely, the more expensive concrete structures are often constructed with a smaller storage volume, hence requiring spring and fall emptying. The pumping operation will trigger the release of very unpleasant odours. Reducing the number of times the manure storage is emptied and field applied is a good approach towards decreasing seasonal inconveniences related to odours for neighbours. Large separation distances allow the dilution of odours under normal climatic conditions. Maintaining large distances between the closest neighbors and a manure storage structure, and siting it such that predominant spring, summer and fall winds usually blow odours away from them, are very good ways to prevent future nuisance problems when planning new operations.
Large setbacks ensures dilution of odours to non-offensive levels in most situations.
Since larger storage structures have a larger surface area for odour emissions, setbacks must be greater for larger operations. Section 6 lists minimum separation distances recommended for siting manure storage structures. Bottom loading of the manure storage - Pumping the manure from the housing to under the liquid manure surface minimizes turbulence in the storage structure and reduces the frequency of offensive odour emissions during the year. Alternatively, it will require a few additional components to the manure handling system. Shelterbelts - Again, shelterbelts will greatly help in diffusing and diluting odours emitted by manure storage structures.
