Farrow-to-finish
Farrow-to-finish is typically a confinement operation where pigs are bred and raised to their slaughter weight, usually 225-300 pounds. Facilities with a capacity of 2,500 or more swine are considered by the EPA to be concentrated animal feeding operations (CAFOs) subject to point source pollution permit requirements. Other types of hog operations include farrow-to-feeder pig, feeder pig-to-finish, weanling-to-feeder pig, and farrow-to-weanling.

Point Source Pollution
A point source of pollution is a single identifiable source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries (such as nonpoint source or area source). The sources are called ''point sources'' because in mathematical modeling, they can be approximated as a mathematical point to simplify analysis. Pollution point sources are identical to other physics, engineering, optics, and chemistry point sources and include: * Air pollution from an industrial source (rather than an airport or a road, considered a line source, or a forest fire, which is considered an area source, or volume source) *Water pollution from factories, power plants, municipal sewage treatment plants and some farms (''see'' concentrated animal feeding operation). The U.S. Clean Water Act also defines municipal separate storm sewer systems and industrial stormwater discharges (such as construction sites) as point so ...
