During storage on farm, slurry emits methane and when manure is spread on fields it emits nitrous oxide and causes nitrogen pollution of land and water.

The 2003 rule established "non-numerical best management practices" (BMPs) for CAFOs that apply both to the "production areas" (e.g. the animal confinement area and the manure storage area) and, for the first time ever, to the "land application area" (land to which manure and other animal waste is applied as fertilizer).
