(18) Erosion and Sediment Control: A system of structural and vegetative measures that minimize soil erosion and off-site sediment pollution.
(19) Farm: Land or water devoted to agriculture as defined by Section 303.01 of the Ohio Revised Code, wherein states "Agriculture includes farming; ranching; aquaculture; horticulture; viticulture; animal husbandry, including, but not limited to the care and raising of livestock, equine and fur-bearing animals; poultry husbandry and the production of poultry and poultry products; dairy production; the production of field crops, tobacco, fruits, vegetables, nursery stock, ornamental shrubs, ornamental trees, flowers, sod, or mushrooms; timber; pasturage; any combination of the foregoing; the processing, drying, storage, and marketing of agriculture products when those activities are conducted in conjunction with, but are secondary to such husbandry or production".
(20) Grassed Waterway: A broad or shallow natural watercourse or constructed channel, covered with erosion-resistant grasses or similar vegetative cover, used to convey surface water.
(21) Impervious: Not allowing infiltration.
(22) Landslide: Rapid movement down-slope of a mass of soil.

(25) Retention Structure: A permanent stormwater management facility that provides for the storage of runoff by means of a permanent pool of water.
(26) Run-off: The portion of rainfall, melted snow, or irrigation water that flows across the ground surface and is eventually returned to streams.
(27) Sediment: Soils or other surface materials that can be transported or deposited by the action of wind, water, ice or gravity as a product of erosion (sedimentation).
(28) Sediment Basin: A barrier or other suitable retention structure built across an area of water flow to intercept run-off and allow transported sediment to settle and be retained, prior to discharge into waters of the State.
(29) Sediment Pollution: Degradation of waters of the state by sediment as a result of failure to apply management or conservation practices to abate wind or water soil erosion, specifically in conjunction with earth-disturbing activities on land used or being developed for commercial, industrial, residential or other non-farm purposes.
(30) Sloughing: A slip or downward movement of an extended layer of soil resulting from the undermining action of water or the earth-disturbing activity of man.
