Underground storage means storage of hazardous liquid in a subsurface stratum or formation of the earth.
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:
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.
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.
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.
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.
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.
Surface water means all water which is open to the atmosphere and subject to surface runoff.
Underground storage tank system means an underground storage tank and the connected underground piping, underground ancillary equipment, and containment system, if any.
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.
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.
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
Storage area means any location, facility, or vehicle which is used to store, to transport, or to secure a radiographic exposure device, a storage container, or a sealed source when it is not in use and which is locked or has a physical barrier to prevent accidental exposure, tampering with, or unauthorized removal of the device, container, or source.
Impervious surface means a surface that has been covered with a layer of material so that it is highly resistant to infiltration by water.
Landing area means that part of a movement area intended for the landing or take-off of aircraft;
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.

Accessible surface means surface of equipment or of an equipment part that can be easily or accidentally touched by persons without the use of a tool.
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.
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.
Basement means any area of the building having its floor subgrade (below ground level) on all sides.
Aboveground tank means a device meeting the definition of tank that is situated in such a way that the entire surface area of the tank is completely above the plane of the adjacent surrounding surface and the entire surface area of the tank (including the tank bottom) is able to be visually inspected.
mining areas means the areas delineated and coloured red on the Plan marked “A” initialled by or on behalf of the parties hereto for the purposes of identification;
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’;
Soil means all unconsolidated mineral and organic material of any origin.
Wellhead protection area means the surface and subsurface area surrounding a water well or well field that supplies a public water system through which contaminants are reasonably likely to migrate toward the water well or well field.
