Runoff Control A large part of the waste associated with many livestock operations includes contaminated runoff from open animal holding areas. Reducing the amount of precipitation that contacts animal waste is a first step, and managing the stormwater that does contact manure is also essential. Runoff from upgradient of the facility should be directed around the areas with manure. Livestock housing and related buildings should have gutters to keep rainwater out of the manure waste stream. Runoff from holding areas can be directed into vegetative buffer strips, grass buffers, or trenches with sorptive material (e.g., bark), or directed overland or in perforated pipes underground to allow soil treatment of the runoff. In some cases, such as outdoor cattle feed lots, runoff from the holding pens is directed downhill to a storage lagoon. Runoff control is described in the following:
