  "text": "In order to reduce ammonia emissions to air from a slurry store, BAT is to use a combination of the techniques given below.\nA description of the techniques is given in Sections 4.6.1 and 4.12.3.\nTechnique\nApplicability\na\nAppropriate design and management of the slurry store by using a combination of the following techniques:\n1.\nReduce the ratio between the emitting surface area and the volume of the slurry store;\nMay not be generally applicable to existing stores.\nExcessively high slurry stores may not be applicable due to increased costs and safety risks.\n2.\nReduce wind velocity and air exchange on the slurry surface by operating the store at a lower level of fill;\nMay not be generally applicable to existing stores.\n3.\nMinimise stirring of slurry.\nGenerally applicable.\nb\nCover the slurry store. For this purpose, one of the following techniques may be used:\n1.\nRigid cover;\nMay not be applicable to existing plants due to economic considerations and structural limitations to withstand the extra load.\n2.\nFlexible covers;\nFlexible covers are not applicable to areas where prevailing weather conditions can compromise their structure.\n3.\nFloating covers such as:\nplastic pellets;\nlight bulk materials;\nfloating flexible covers;\ngeometrical plastic tiles;\nair-inflated cover;\nnatural crust;\nstraw.\nThe use of plastic pellets, light bulk materials and geometrical plastic tiles is not applicable to naturally crusting slurries.\nAgitation of the slurry during stirring, filling and emptying may preclude the use of some floating materials which may cause sedimentation or blockages in the pumps.\nNatural crust formation may not be applicable to cold climates and/or to slurry with low dry matter content.\nNatural crust is not applicable to stores where stirring, filling and/or discharging of slurry renders the natural crust unstable.\nc\nSlurry acidification.\nGenerally applicable.",
