HOTSPOT. An area where land use or activities generate highly contaminated runoff, with concentrations of pollutants in excess of those typically found in stormwater.
HYDROLOGIC SOIL GROUP (HSG). A natural resource conservation service classification system in which soils are categorized into 4 runoff potential groups. The groups range from A soils, with high permeability and little runoff production, to D soils, which have low permeability rates and produce much more runoff.
IMPERVIOUS COVER. Those surfaces that cannot effectively infiltrate rainfall (e.g., building rooftops, pavement, sidewalks, driveways, and the like).
INDUSTRIAL STORMWATER PERMIT. A national 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 specifies on-site pollution control strategies.
INFILTRATION. The process of percolating stormwater into the subsoil.
INFILTRATION FACILITY. Any structure or device designed to infiltrate retained water to the subsurface. These facilities may be above grade or below grade.
JESSAMINE COUNTY MS4 COMMITTEE (JCMS4C). A committee appointed by the Jessamine County Fiscal Court whose purpose is to monitor the Jessamine County MS4 program.
JURISDICTIONAL WETLAND. An 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 DISTURBANCE ACTIVITY. Any activity which changes the volume or peak flow discharge rate of rainfall runoff from the land surface. This may include the grading, digging, cutting, scraping, or excavating of soil, placement of fill materials, paving, construction, substantial removal of vegetation, or any activity which bares soil or rock or involves the diversion or piping of any natural or man-made watercourse.
MAINTENANCE AGREEMENT. A legally recorded document that acts as a property deed restriction, and which provides for long-term maintenance of stormwater management plan.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES). The program administered by the United States Environmental Protection Agency to eliminate or reduce pollutant discharges to the water of the United States. In Kentucky, known as the Kentucky Pollutant Discharge Elimination System (KPDES).
NON-POINT SOURCE POLLUTION. Pollution 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.
ONE HUNDRED YEAR FLOODPLAIN. The area of land adjacent to a stream that is subject to inundation during a storm event which has a 1% chance of being equaled or exceeded in any given year.
ON-SITE FACILITY. A stormwater management measure located within the subject property boundary described in the permit application for land development activity.
POLLUTANT. Dredged spoil, solid waste, incinerator residue, sewage, sewage sludge, garbage, chemical, biological or radioactive materials, heat, wrecked or discarded equipment, rock, sand, soil, industrial, municipal or agricultural waste, and any substance resulting from the development, processing, or recovery of any natural resource which may be discharged into water. (See KRS 224.01-010(35))
POLLUTION. Any contamination or alteration of the physical, chemical, or biological properties of any waters that will render the waters harmful or detrimental to: public health, safety or welfare; domestic, commercial, industrial, agricultural, recreational, or other legitimate beneficial uses; livestock, wild animals, or birds; fish or other aquatic life.
RECHARGE. The replenishment of underground water reserves.
RUNOFF. The water resulting from precipitation that is not absorbed by the soil.
SEDIMENT. Soils or other surficial materials transported or deposited by the action of wind, water, ice, or gravity as a product of erosion.
STOP WORK ORDER. A cease and desist order issued which requires that all construction activity on a site be stopped.
STORMWATER. Means stormwater runoff, snow melt runoff, surface runoff and drainage.
STORMWATER MANAGEMENT. The use of structural or non-structural practices that are designed to reduce stormwater runoff pollutant loads, discharge volumes, peak flow discharge rates and detrimental changes in stream temperature that affect water quality and habitat.
STORMWATER MANAGEMENT PLAN (SWMPL). An overall plan for a development which uses structural or non-structural practices designed to reduce stormwater runoff pollutant loads, discharge volumes, peak flow discharge rates and detrimental changes in stream temperature that affect water quality and habitat meeting the requirements of this chapter.
STORMWATER MANAGEMENT PRACTICES (SWMPR). Measures, either structural or nonstructural, that are determined to be the most effective, practical means of preventing or reducing stormwater runoff pollutant loads, discharge volumes, peak flow discharge rates and detrimental changes in stream temperature that affect water quality and habitat meeting the requirements of this chapter.
STORMWATER POLLUTION PREVENTION PLAN (SWPPP). A site-specific, written document required for submission of the KPDES Notice of Intent (NOI) and this chapter. The SWPPP is utilized during construction and for post-construction conditions to identify potential sources of pollution, describe practices to reduce pollutants in stormwater discharges, and identify implementation procedures to maintain compliance with the current general permit.
