Irrigation means application of water to land areas to supply the water needs of
Excavation zone means the volume containing the tank system and backfill material bounded by the ground surface, walls, and floor of the pit and trenches into which the UST system is placed at the time of installation.
Irrigation System means such major, medium and minor irrigation system for harnessing water for irrigation and other allied uses from Government source and includes reservoirs, open head channels, diversion systems, lift irrigation schemes, anicuts, tanks, wells and the like.
Sanitary landfill means an engineered land burial facility for the disposal of household waste that is so located, designed, constructed, and operated to contain and isolate the waste so that it does not pose a substantial present or potential hazard to human health or the environment. A sanitary landfill also may receive other types of solid wastes, such as commercial solid waste, nonhazardous sludge, hazardous waste from conditionally exempt small quantity generators, construction, demolition, or debris waste and nonhazardous industrial solid waste. See 9VAC20-81 (Solid Waste Management Regulations) for further definitions of these terms.
Irrigation efficiency (IE) means the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The irrigation efficiency for purposes of this ordinance are 0.75 for overhead spray devices and 0.81 for drip systems.
Drip irrigation means any non-spray low volume irrigation system utilizing emission devices with a flow rate measured in gallons per hour. Low volume irrigation systems are specifically designed to apply small volumes of water slowly at or near the root zone of plants.
Sanitary Sewer Overflow or “SSO” means any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from the sanitary sewer system. SSOs include:
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Irrigation district means a local district that operates under and is subject to the provisions of this chapter and Chapter 2a, Part 5, Irrigation District Act, including an entity that was created and operated as an irrigation district under the law in effect before April 30, 2007.
Sanitary Sewage means wastewaters from residential, commercial and industrial sources introduced by direct connection to the sewerage collection system tributary to the treatment works including non-excessive inflow/infiltration sources.
overlay zone means a mapped overlay superimposed on one or more established zoning areas which may be used to impose supplemental restrictions on uses in these areas or permit uses otherwise disallowed;
Sanitary sewerage means a system of public sewers for carrying off waste water and refuse, but excluding sewage treatment facilities, septic tanks, and leach fields owned or operated by the licensee or registrant.
Loading Zone means a parking stall which is set aside for use by commercial vehicles if there is a sign referable to that stall marked ‘Loading Zone’;
Underground storage means storage of hazardous liquid in a subsurface stratum or formation of the earth.
Water Surface Elevation (WSE means the height, in relation to mean sea level, of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.
Underground source of drinking water means an aquifer or its portion:
Surface water means all water which is open to the atmosphere and subject to surface runoff.
Drainage means the movement of water to a place of disposal, whether by way of the natural characteristics of the ground surface or by artificial means;
Sanitary Sewer System means all facilities, includ- ing approved LOSS, used in the collection, transmission, storage, treatment, or discharge of any waterborne waste, whether domestic in origin or a combination of domestic, commercial, or industrial wastewater. LOSS are only consid- ered sanitary sewer systems if they are designed to serve urban densities. Sanitary sewer system is also commonly known as public sewer system.
Water surface elevation means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929, the North American Vertical Datum (NAVD) of 1988, or other datum, where specified, of floods of various magnitudes and frequencies in the floodplains of riverine areas.
Drainage area means a geographic area within which stormwater, sediments, or dissolved materials drain to a particular receiving waterbody or to a particular point along a receiving waterbody.
Underground storage tank or “UST” means any one or combination of tanks (including underground pipes connected thereto) that is used to contain an accumulation of regulated substances, and the volume of which (including the volume of underground pipes connected thereto) is 10 percent or more beneath the surface of the ground. This term does not include any:
Curbside “Curb” means that portion of the right-of-way adjacent to paved or traveled roadways, including the end of a driveway, curb line or alley line. Containers will be placed as close to the roadway as practicable without interfering with or endangering the movement of vehicles or pedestrians.
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
Channel migration zone (CMZ) means the area where the active channel of a stream is prone to move and this results in a potential near-term loss of riparian function and associated habitat adjacent to the stream, except as modified by a permanent levee or dike. For this purpose, near-term means the time scale required to grow a mature forest. (See board manual section 2 for descriptions and illustrations of CMZs and delineation guidelines.)
Sanitary Sewer means a sewer which carries sewage and to which storm, surface, and ground waters are not intentionally admitted.
