This Ozarks At Large report by Jacqueline Froelich focuses on the battle between Oklahoma and Arkansas over pollution, primarily phosphorus, of the Illinois River by Arkansas poultry producers. While not directly related to hog CAFOs, it does show how industry will attempt to weaken and undermine efforts to protect water quality. The warning for me is that when phosphorus levels (or other pollutants) rise in the Buffalo attributable to C & H hog farm, industry will inevitably attempt to establish "tolerable" levels. This explains ADEQ's comments that CAFOs will no doubt have an impact on the Buffalo, and other waters of the state, but the issue for them is where "impact" causes "harm". Who gets to define "harm"?
