Observed excessive slumping, erosion, or movement of biosolids is to be corrected within 24 hours. Any ponding at the site is to be corrected and any malodor shall be addressed in accordance with the odor control plan. The certified land applier shall maintain documentation of the inspections of staged biosolids; and

11. Staged biosolids shall be managed so as to prevent adverse impacts to water quality or public health.
