Section 570.102 Definitions
Except as hereinafter stated,
and unless a different meaning of the term is clear from its context, the
definitions of terms used in this document shall be the same as those used in
the Environmental Protection Act and Illinois Pollution Control Board Regulations,
Chapter 3 – Water Pollution (Title 35, Subtitle C, Chapter 1) and Chapter 5 –
Livestock Wastes:
Distribution Manifold: A device designed, constructed and
maintained to provide uniform sheet flow of settling basin effluent across the
width of a runoff field application area.
Effluent Transport System (ETS): A non-perforated pipe or
other device designed, constructed, and maintained to transport settling basin
effluent to a junction box and distribution manifold.
Field Application Area (FAA): A vegetated area designed,
constructed, and maintained to remove sediment, organic matter, and other
pollutants from livestock management facility runoff by settling, dilution,
absorption, adsorption, infiltration, assimilation, and other processes.
Junction Box: A device designed, constructed, and maintained
to dissipate the energy of the anticipated hydraulic jump from the effluent
transport system discharge and to proportionally split the flow to the
distribution manifold(s).
Livestock Waste: Livestock excreta and associated feed
losses; bedding; wash waters; sprinkling waters from livestock cooling; solids
removed from settling basins, lagoons, or holding ponds; precipitation polluted
by falling on or flowing onto an animal feeding operation; and other materials
polluted by livestock.
Runoff Field Application System: Those collective
constructions or devices, except sewers, used to collect, pump, settle, store,
and land apply feedlot runoff which include, but are not limited to, settling
basin, effluent transport system, junction box, distribution manifold, and
field application area.
Settling Basin: A basin designed, constructed, and
maintained to remove settleable solids in feedlot runoff by gravity.
SI: Soil infiltration rate (inches per hour).
VR: volume of feedlot runoff to be infiltrated by the field
application area (cubic feet).
QF: Design flow rate (gallons per minute) over the field
application area at ½ inch depth of flow for a 2 hour contact time.
