313-18 <br /> D. Specific Criteria For Temporary,Unconfined Conservation BMPs shall be used above stacking <br /> Stacks of Manure and Derivatives Outside the sites to divert overland flow,and below stacking <br /> Animal Production Area sites to provide containment or buffering to <br /> downstream channels and lakes. <br /> This includes solid type manure and derivatives <br /> that are deposited for subsequent loading and The maximum amount of manure that is stacked <br /> spreading.Waste material having less than 16% on any one field shall be limited to the nutrient <br /> solids shall not be stacked in the field.Storage of needs of fields adjacent to the stacking site in <br /> these materials shall be in facilities meeting the accordance with a 590 nutrient management <br /> criteria in section V.B.1 and 2.Criteria for plan. <br /> unconfined waste stacks are shown in Table 10. <br /> Table 10-Temporary,Unconfined Stacks of Manure and Derivatives Outside the Animal Production Area <br /> 1.
