Regulations governing animal waste storage are primarily a state-level issue. Protecting water resources from animal waste contamination will depend upon how effective state-level animal waste regulations are in encouraging livestock producers to handle waste appropriately. Survey results from North Dakota indicate beef cattle feeding operations do not always comply with state regulations requiring adoption of manure storage BMP's. This is most likely due to incomplete inspection schedules by the regulatory agency. Statistical results suggest herd size plays a much larger role than regulation in promoting adoption of manure storage BMP's.
