Sec. 650.205  Definitions.

    Erosion control measures and practices are actions that are taken to 
inhibit the dislodging and transporting of soil particles by water or 
wind, including actions that limit the area of exposed soil and minimize 
the time the soil is exposed.
    Permanent erosion and sediment control measures and practices are 
installations and design features of a construction project which remain 
in place and in service after completion of the project.
    Pollutants are substances, including sediment, which cause 
deterioration of water quality when added to surface or ground waters in 
sufficient quantity.
    Sediment control measures and practices are actions taken to control 
the deposition of sediments resulting from surface runoff.
    Temporary erosion and sediment control measures and practices are 
actions taken on an interim basis during construction to minimize the 
disturbance, transportation, and unwanted deposition of sediment.
