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.

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.
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:
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.
Subsurface tracer study means the release of a substance tagged with radioactive material for the purpose of tracing the movement or position of the tagged substance in the well-bore or adjacent formation.
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.
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
Soil means all unconsolidated mineral and organic material of any origin.
Building Square Footage or "BSF" means the square footage of assessable internal living space of a Unit, exclusive of any carports, walkways, garages, overhangs, patios, enclosed patios, detached accessory structure, other structures not used as living space, or any other square footage excluded under Government Code Section 65995 as determined by reference to the Building Permit for such Unit.
Aboveground storage tank shall have the meaning ascribed to such term in Section 6901 et seq., as amended, of RCRA, or any applicable state or local statute, law, ordinance, code, rule, regulation, order ruling, or decree governing aboveground storage tanks.
Underground storage tank system means an underground storage tank and the connected underground piping, underground ancillary equipment, and containment system, if any.
Transboundary movement means any movement of hazardous wastes or other wastes from an area under the national jurisdiction of one State to or through an area under the national jurisdiction of another State or to or through an area not under the national jurisdiction of any State, provided at least two States are involved in the movement;

Underground storage means storage of gas in a subsurface stratum or formation of the earth.
Project Site(s) means the place(s) specified in the SCC for the supply and installation of the System.
Area of shallow flooding means a designated AO or AH Zone on a community's Flood Insurance Rate Map (FIRM) with one percent or greater annual chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate; and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
Invasive plant species means species of plants not historically found in California that spread outside cultivated areas and can damage environmental or economic resources. Invasive species may be regulated by county agricultural agencies as noxious species. Lists of invasive plants are maintained at the California Invasive Plant Inventory and USDA invasive and noxious weeds database.
Uppermost aquifer means the geologic formation nearest the natural ground surface that is an aquifer, as well as lower aquifers that are hydraulically interconnected with this aquifer within the facility's property boundary.
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;
Impact surface means an interior or exterior surface that is subject to damage by repeated sudden force such as certain parts of door frames.
Storage tank means an aboveground storage tank or underground storage tank as defined by this Regulation.
Project site, where applicable, means the place indicated in bidding documents.
