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.
Impoundment means a closed basin, naturally formed or artificially built, which is dammed or excavated for the retention of water, sediment, or waste.
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.
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”.)
Tank means an enclosed space which is formed by the permanent structure of a ship and which is designed for the carriage of liquid in bulk.
Storage Facility means a facility used for the stocking of natural gas and owned and/or operated by a natural gas undertaking, including the part of LNG facilities used for storage but excluding the portion used for production operations, and excluding facilities reserved exclusively for transmission system operators in carrying out their functions;
Storage means any keeping or retention of tangible personal property for use, consumption or
Underground area means an underground room, such as a basement, cellar, shaft or vault, providing enough space for physical inspection of the exterior of the tank situated on or above the surface of the floor.
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;
Easement Area means the area of the servient lot marked on the survey-strata plan as being subject to the relevant easement; and
Storage tank means an aboveground storage tank or underground storage tank as defined by this Regulation.
Underground tank means a device meeting the definition of tank whose entire surface area is totally below the surface of and covered by the ground.
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:
Sanitary landfill means an engineered land burial facility for the disposal of household waste which 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 debris, and nonhazardous industrial solid waste.
Regulated impervious surface means any of the following, alone or in combination:
Stockpile means material, including, but not limited to, surface overburden, rock, or lean ore, that in the process of mining and beneficiation or treatment has been removed from the earth and stored on the surface. Stockpile does not include materials that are being treated in the production of metallic products and the metallic product that has been produced by that operation.
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).
Slug loading means any pollutant, including oxygen demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration as to cause interference in the POTW.
stacked bicycle parking space means a horizontal bicycle parking space that is positioned above or below another bicycle parking space and equipped with a mechanical device providing floor level access to both bicycle parking spaces.
Loading Space means an off-street space or berth on the same lot or parcel with a building or use, or contiguous to a group of buildings or uses, for the temporary parking of a vehicle while loading or unloading persons, merchandise or materials, and which space or berth abuts on a street, alley or other appropriate means of access.
Basement means any area of the building having its floor subgrade (below ground level) on all sides.
Underground storage tank system means an underground storage tank and the connected underground piping, underground ancillary equipment, and containment system, if any.
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.
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:
Loading means the quantity of a specific substance present per unit of surface area, such as the amount of lead in micrograms contained in the dust collected from a certain surface area divided by the surface area in square feet or square meters.
