Environmental concerns being addressed by this rule include both ecological and human health effects. Manure from stockpiles, lagoons, or excessive land application can reach waterways through runoff, erosion, spills, or via groundwater.

This pollution can kill fish and shellfish, cause excess algae growth, harm m…
