wetted surface means that area of a solid waste disposal cell or trench excavation surface that is in contact with solid or liquid waste;
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.
Pervious surface means an area that releases as runoff a small portion of the precipitation that falls on it. Lawns, gardens, parks, forests or other similar vegetated areas are examples of surfaces that typically are pervious.
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.
Impervious surface means a surface that has been covered with a layer of material so that it is highly resistant to infiltration by water.
Contaminated site means a site where there is a confirmed presence, caused by man, of hazardous substances of such a level that they pose a significant risk to human health or the environment taking into account current and approved future use of the land;
Surface impoundment or "impoundment" means a facility or part of a facility which is a natural topographic depression, man-made excavation, or diked area formed primarily of earthen materials (although it may be lined with man-made materials), which is designed to hold an accumulation of liquid wastes or wastes containing free liquids, and which is not an injection well. Examples of surface impoundments are holding, storage, settling, and aeration pits, ponds, and lagoons.
Soil means all unconsolidated mineral and organic material of any origin.
Contaminated soil means soil that meets all of the following criteria:
Contaminate means the addition of sediment, any other pollutant or waste, or any illicit or prohibited discharge.
Surface water means all water which is open to the atmosphere and subject to surface runoff.
Groundwater means all water, which is below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil.
Hazardous Materials Contamination means contamination (whether now existing or hereafter occurring) of the improvements, buildings, facilities, personalty, soil, groundwater, air or other elements on or of the relevant property by Hazardous Materials, or any derivatives thereof, or on or of any other property as a result of Hazardous Materials, or any derivatives thereof, generated on, emanating from or disposed of in connection with the relevant property.
Infiltrative surface means designated interface where effluent moves from distribution media or a distribution product into treatment media or original soil. In standard trench or bed systems this will be the interface of the distribution media or product and in-situ soil. Two separate infiltrative surfaces will exist in a mound system and an unlined sand filter, one at the interface of the distribution media and fill sand, the other at the interface of the fill sand and in-situ soil.
Surface mining means mining by removing the overburden lying above the natural deposits and excavating directly from the natural deposits exposed, or by excavating directly from deposits lying exposed in their natural state and shall include dredge operations conducted in or on natural waterways or artificially created waterways within the state.
Mine drainage means any drainage, and any water pumped or siphoned, from an active mining area or a post-mining area. The abbreviation “ml/l” means milliliters per liter.
Contamination means the presence of, or Release on, under, from or to the environment of any Hazardous Substance, except the routine storage and use of Hazardous Substances from time to time in the ordinary course of business, in compliance with Environmental Laws and with good commercial practice.
Environmental Contamination means the introduction or presence of Hazardous Materials at such levels, quantities or location, or of such form or character, as to constitute a violation of federal, state or local laws or regulations, and present a material risk under federal, state or local laws and regulations that the Premises will not be available or usable for the purposes contemplated by this Agreement.
Underground injection means the subsurface emplacement of fluids through a bored, drilled or driven well; or through a dug well, where the depth of the dug well is greater than the largest surface dimension. (See also “injection well”.)
Building site means a plot of land held for building purposes, whether any building is actually erected thereupon or not, and includes the open ground or courtyard enclosed by, or adjacent to, any building erected thereupon;
impermeable surface means a surface or pavement constructed and maintained to a standard sufficient to prevent the transmission of liquids beyond the pavement surface, and should be read in conjunction with the term “sealed drainage system” (below).
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
Contaminated means the actual existence on or under any real property of Hazardous Substances, if the existence of such Hazardous Substances triggers a requirement to perform any investigatory, remedial, removal or other response action under any Environmental Laws or if such response action legally could be required by any governmental authority; "Facility" means any property currently owned, leased or occupied by the Company.
Excavation means the mechanical removal of earth material.
Geologically hazardous areas means areas that because of their susceptibility to erosion, sliding, earthquake, or other geological events, are not suited to the siting of commercial, residential, or industrial development consistent with public health or safety concerns.
Lead-contaminated dust means surface dust that contains an area or mass concentration of lead at or in excess of levels identified by the Environmental Protection Agency pursuant to § 403 of TSCA (15 U.S.C. § 2683).
Underground facility means any item which shall be buried or placed below ground for use in connection with the storage or conveyance of water, sewage, electronic, telephone or telegraphic communications, electric energy, oil, gas or other substances, and shall include, but not be limited to pipes, sewers, conduits, cables, valves, lines, wires, manholes, attachments and those portions of poles and their attachments below ground.
