The terms used in this chapter or in documents prepared or reviewed under this chapter shall have the meanings as set forth:
AGRICULTURAL ACTIVITYThe activity of an active farm, including grazing and watering livestock, irrigating crops, harvesting crops, using land for growing agricultural products, and cutting timber for sale, but shall not include the operation of a dude ranch or similar operation, or the construction of new structures associated with agricultural activities.
BUILDINGAny structure, either temporary or permanent, having walls and a roof, designed for the shelter of any person, animal, or property, and occupying more than 100 square feet of area.
CATCH BASIN (drain inlet)A structure which allows the entry of surface runoff into a storm sewer by connection to the storm sewer.
CHANNELA natural or artificial watercourse with a definite bed and banks that conducts continuously or periodically flowing water.
CLEARINGAny activity that removes the vegetative surface cover.
DEDICATIONThe deliberate appropriation of property by its owner for general public use.
DEPARTMENTThe New York State Department of Environmental Conservation.
DESIGN MANUALThe New York State Stormwater Design Manual, most recent version, including applicable updates, that serves as the official guide for stormwater management principles, methods and practices.
DETENTION STRUCTUREA permanent stormwater management structure whose primary purpose is to temporarily store stormwater runoff. A detention structure may be dry during nonstorm events or may have a permanent pool of water.
DEVELOPERA person who undertakes land development activities.
EROSION CONTROL MANUALThe most recent version of the New York Standards and Specifications for Erosion and Sediment Control manual, commonly known as the "Blue Book."
FIRST FLUSHThe delivery of a disproportionately large load of pollutants during the early part of storms due to the rapid runoff of accumulated pollutants. The first flush is defined as the runoff generated from the first 1/2 inch of runoff from the entire site from land which has been made less pervious than the predevelopment conditions though land grading and/or construction/development activities.
GRADINGExcavation or fill of material, including the resulting conditions thereof.
IMPERVIOUS COVERThose surfaces, improvements and structures that cannot effectively infiltrate rainfall, snowmelt and water (e.g., building rooftops, pavement, sidewalks, driveways, etc.).
INDUSTRIAL STORMWATER PERMITA State Pollutant Discharge Elimination System permit issued to a commercial industry or group of industries which regulates the pollutant levels associated with industrial stormwater discharges or specific on-site pollution control strategies.
INFILTRATIONThe process of percolating water into the subsoil.
JURISDICTIONAL WETLANDAn area that is inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support a prevalence of vegetation typically adapted for life in saturated soil conditions, commonly known as "hydrophytic vegetation."
LAND DEVELOPMENT ACTIVITYConstruction activity, including clearing, grading, excavating, soil disturbance or placement of fill, that results in land disturbance of equal to or greater than one acre or activities disturbing less than one acre of total land area that is part of a larger common plan of development or sale, even though multiple separate and distinct land development activities may take place at different times on different schedules.
LANDOWNERThe legal or beneficial owner of land, including those holding the right to purchase or lease the land, or any other person holding proprietary rights in the land.
MAINTENANCE AGREEMENTA legally recorded document that acts as a property deed restriction, and which provides for long-term maintenance of stormwater management practices.
NONPOINT SOURCE POLLUTIONPollution from any source other than from any discernible, confined, and discrete conveyances, and shall include, but not be limited to, pollutants from agricultural, silvicultural, mining, construction, subsurface disposal and urban runoff sources.
PHASINGDeveloping a parcel of land in distinct pieces or parts, with the stabilization of each place completed before the development of the next.
POLLUTANT OF CONCERNSediment or a water quality measurement that addresses sediment (such as total suspended solids, turbidity or siltation) and any other pollutant that has been identified as a cause of impairment of any water body that will receive a discharge from the land development activity.
RECHARGEThe replenishment of underground water reserves.
RETENTIONA practice designed to store stormwater runoff by collection as a permanent pool of water without release except by means of evaporation, infiltration, or attenuated release when runoff volumes exceed the storage capacity of the pool.
SEDIMENTSolid material, both mineral and organic, that is in suspension, is being transported, or has been removed from its site of origin by erosion.
SENSITIVE AREASCold water fisheries, shellfish beds, swimming beaches, groundwater recharge areas, water supply reservoirs, habitats for threatened, endangered or special concern species, critical environmental areas designated by the municipality.
STABILIZATIONThe use of practices that prevent exposed soil from eroding.
STOP-WORK ORDERAn order issued which requires that all construction activity on a site be stopped.
STORMWATERRainwater surface runoff, snowmelt and drainage.
STORMWATER HOTSPOTA land use or activity that generates higher concentrations of hydrocarbons, trace metals or toxicants than are found in typical stormwater runoff, based on monitoring studies.
STORMWATER MANAGEMENTThe use of structural or nonstructural practices that are designed to reduce stormwater runoff and mitigate its adverse impacts on property, natural resources and the environment.
STORMWATER MANAGEMENT FACILITYOne or a sense of stormwater management practices installed, stabilized and operated for the purpose of controlling stormwater runoff.
STORMWATER MANAGEMENT OFFICERAn employee or officer designated by the municipality to accept and review stormwater pollution prevention plans, forward the plans to the applicable municipal board and inspect stormwater management practices.
STORMWATER MANAGEMENT PRACTICES (SMPs)Measures, either structural or nonstructural, that are determined to be the most effective, practical means of preventing flood damage and preventing or reducing point source or nonpoint source pollution inputs to stormwater runoff and water bodies.
STRIPPINGAny activity which removes or significantly disturbs trees, brush, grass, or any other kind of vegetation.
SURFACE WATERS OF THE STATE OF NEW YORKLakes, bays, sounds, ponds, impounding reservoirs, springs, wells, rivers, streams, creeks, estuaries, marshes, inlets, canals, the Atlantic Ocean within the territorial seas of the State of New York and all other bodies of surface water, natural or artificial, inland or coastal, fresh or salt, public or private (except those private waters that do not combine or effect a junction with natural surface or underground waters), which are wholly or partially within or bordering the state or within its jurisdiction. Storm sewers and waste treatment systems, including treatment ponds or lagoons which also meet the criteria of this definition are not waters of the state. This exclusion applies only to man-made bodies of water which neither were originally created in waters of the state (such as a disposal area in wetlands) nor resulted from impoundment of waters of the state.
SWALEA natural depression or wide shallow ditch used to route or filter runoff.
WATERCOURSEA permanent or intermittent stream or other body of water, either natural or man-made, which gathers or carries surface water.
WATERSHEDA region or area contributing stormwater ultimately to a particular watercourse or body of water.
WATERWAYA channel that directs surface runoff to a watercourse or to the public storm drain.
