"Air curtain incinerator" means an incinerator that operates by forcefully projecting a curtain of air across an open chamber or pit in which combustion occurs. Incinerators of this type can be constructed above or below ground and with or without refractory walls and floor. Air curtain incinerators are not to be confused with conventional combustion devices with enclosed fireboxes and controlled air technology such as mass burn, modular, and fluidized bed combustors.

"Automobile graveyard" means any lot or place that is exposed to the weather and upon which more than five motor vehicles of any kind, incapable of being operated, and that it would not be economically practical to make operative, are placed, located or found.

"Clean burning waste" means waste that is not prohibited to be burned under this chapter and that consists only of (i) 100% wood waste, (ii) 100% clean lumber or clean wood, (iii) 100% yard waste, or (iv) 100% mixture of only any combination of wood waste, clean lumber, clean wood or yard waste.

"Clean lumber" means wood or wood products that have been cut or shaped and include wet, air-dried, and kiln-dried wood products. Clean lumber does not include wood products that have been painted, pigment-stained, or pressure-treated by compounds such as chromate copper arsenate, pentachlorophenol, and creosote.

"Clean wood" means uncontaminated natural or untreated wood. Clean wood includes, but is not limited to, byproducts of harvesting activities conducted for forest management or commercial logging, or mill residues consisting of bark, chips, edgings, sawdust, shavings or slabs. It does not include wood that has been treated, adulterated, or chemically changed in some way; treated with glues, binders or resins; or painted, stained or coated.

"Commercial waste" means all solid waste generated by establishments engaged in business operations other than manufacturing or construction. This category includes, but is not limited to, waste resulting from the operation of stores, markets, office buildings, restaurants and shopping centers.

"Construction waste" means solid waste that is produced or generated during construction, remodeling, or repair of pavements, houses, commercial buildings and other structures. Construction waste consists of lumber, wire, sheetrock, broken brick, shingles, glass, pipes, concrete, and metal and plastics if the metal or plastics are a part of the materials of construction or empty containers for such materials. Paints, coatings, solvents, asbestos, any liquid, compressed gases or semi-liquids, and garbage are not construction wastes and the disposal of such materials shall be in accordance with the regulations of the Virginia Waste Management Board.

"Debris waste" or "vegetative debris" means wastes resulting from land clearing operations. Debris wastes include but are not limited to stumps, wood, brush, leaves, soil and road spoils.

"Demolition waste" means that solid waste that is produced by the destruction of structures, or their foundations, or both, and includes the same materials as construction waste.

"Garbage" means readily putrescible discarded materials composed of animal, vegetable or other organic matter.

"Hazardous waste" means a "hazardous waste" as described in 9VAC20-60 (Virginia Hazardous Waste Management Regulations).

"Household waste" means any waste material, including garbage, trash and refuse derived from households. For purposes of this regulation, households include single and multiple residences, hotels and motels, bunkhouses, ranger stations, crew quarters, campgrounds, picnic grounds and day-use recreation areas. Household wastes do not include sanitary waste in septic tanks (septage) that is regulated by other state agencies.

"Industrial waste" means any solid waste generated by manufacturing or industrial process that is not a regulated hazardous waste. Such waste may include but is not limited to waste resulting from the following manufacturing processes: electric power generation; fertilizer/agricultural chemicals; food and related products/byproducts; inorganic chemicals; iron and steel manufacturing; leather and leather products; nonferrous metals manufacturing/foundries; organic chemicals; plastics and resins manufacturing; pulp and paper industry; rubber and miscellaneous plastic products; stone, glass, clay and concrete products; textile manufacturing; transportation equipment; and water treatment. This term does not include mining waste or oil and gas waste.

"Junk" means old or scrap copper, brass, rope, rags, batteries, paper, trash, rubber, debris, waste, or junked, dismantled, or wrecked automobiles, or parts thereof, iron, steel, and other old or scrap ferrous or nonferrous material.

"Junkyard" means an establishment or place of business that is maintained, operated, or used for storing, keeping, buying, or selling junk, or for the maintenance or operation of an automobile graveyard, and the term shall include garbage dumps and sanitary landfills.

"Landfill" means a sanitary landfill, an industrial waste landfill, or a construction/demolition/debris landfill. See Part I (9VAC20-81-10 et seq.) of 9VAC20-81 (Solid Waste Management Regulations) for further definitions of these terms.

"Local landfill" means any landfill located within the jurisdiction of a local government.

"Open burning" means the combustion of solid waste without:

1. Control of combustion air to maintain adequate temperature for efficient combustion;

2. Containment of the combustion reaction in an enclosed device to provide sufficient residence time and mixing for complete combustion; and

3. Control of the combustion products' emission.

"Open pit incinerator" means a device used to burn waste for the primary purpose of reducing the volume by removing combustible matter. Such devices function by directing a curtain of air at an angle across the top of a trench or similarly enclosed space, thus reducing the amount of combustion byproducts emitted into the atmosphere. The term also includes trench burners, air curtain incinerators and over draft incinerators.

"Refuse" means all solid waste products having the characteristics of solids rather than liquids and that are composed wholly or partially of materials such as garbage, trash, rubbish, litter, residues from clean up of spills or contamination or other discarded materials.

"Regular burn site" means state controlled property where burning conducted by the Virginia Department of Transportation is expected to occur greater than once per year.

"Salvage operation" means any operation consisting of a business, trade or industry participating in salvaging or reclaiming any product or material, such as, but not limited to, reprocessing of used motor oils, metals, chemicals, shipping containers or drums, and specifically including automobile graveyards and junkyards.

"Sanitary landfill" means an engineered land burial facility for the disposal of household waste that 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, or debris waste and nonhazardous industrial solid waste. See Part I (9VAC20-81-10 et seq.) of 9VAC20-81 (Solid Waste Management Regulations) for further definitions of these terms.

"Smoke" means small gas-borne particulate matter consisting mostly, but not exclusively, of carbon, ash and other material in concentrations sufficient to form a visible plume.

"Special incineration device" means an open pit incinerator, conical or teepee burner, or any other device specifically designed to provide good combustion performance.
