Contaminated soil means soil that meets all of the following criteria:
Soil means all unconsolidated mineral and organic material of any origin.
Topsoil means a varying depth (up to 300 mm) of the soil profile irrespective of the fertility, appearance, structure, agricultural potential, fertility and composition of the soil;
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
Hydric soil means a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part.
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.
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.
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;
Drywell means an unlined or partially lined underground pit (regardless of geometry) into which drainage from roofs, basement floors, water softeners or other non-wastewater sources is discharged and from which the liquid seeps into the surrounding soil.
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.
Tailings means material rejected from a mill after most of the valuable minerals have been extracted.
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.
Sedimentation means a process for removal of solids before filtration by gravity or separation.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
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;
Reservoir means a porous and permeable underground formation containing a natural accumulation of producible oil or gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs.
Underground storage means storage of hazardous liquid in a subsurface stratum or formation of the earth.
Navigable waters ’ means the waters of the United States, including the territorial sea;
Biomass means the biodegradable fraction of products, waste and residues from biological origin from agriculture (including vegetal and animal substances), forestry and related industries including fisheries and aquaculture, as well as the biodegradable fraction of industrial and municipal waste;
Combustion turbine means an enclosed fossil or other fuel-fired device that is comprised of a compressor, a combustor, and a turbine, and in which the flue gas resulting from the combustion of fuel in the combustor passes through the turbine, rotating the turbine.
Potable means water suitable for drinking by the public.
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 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”.)
Underground mining means all methods of mining other than surface mining.
Sediment means solid material, mineral or organic, that is in suspension, is being transported, or has been moved from its site of origin by air, water or gravity as a product of erosion.
