  22.  “Settled open feedlot effluent” or “settled effluent” means a combination of manure, precipitation-induced runoff, or other runoff originating from an open feedlot after its settleable solids have been removed.
  23.  “Settled open feedlot effluent basin” or “basin” means an impoundment which is part of an open feedlot operation, if the primary function of the impoundment is to collect and store settled open feedlot effluent.
  24.  “Solids settling facility” means a basin, terrace, diversion, or other structure or solids removal method which is part of an open feedlot operation and which is designed and operated to remove settleable solids from open feedlot effluent. A “solids settling facility” does not include a basin, terrace, diversion, or other structure or solids removal method which retains the liquid portion of open feedlot effluent for more than seven consecutive days following a precipitation event.
  25.  “Stockpile” means to store solids from an open feedlot operation outside of an open feedlot operation structure or outside of an area that drains to an open feedlot operation structure.
