				excavation of contaminated soil from its original location followed by
				treatment off-site.
15. "Facility"
				means all contiguous land, structures, other appurtenances and improvements on
				the land used for treating and storing waste. A facility may consist of several
				treatment, storage, or disposal operational units.
16. "Generator" means any person whose act or
				process produces or results in contaminated soil.
17. "Incineration" means an ex-situ
				technology that uses heating to volatilize and combust organic
				constituents.
18. "In-situ" means
				the treatment of contaminated soil on-site without excavation of the
				soil.
19. "Leachate" means a liquid
				that has passed through or emerged from contaminated soil and contains soluble,
				suspended, or miscible materials removed from such soil.
20. "Low-Temperature Thermal Desorption"
				(LTTD), also known as "low-temperature thermal volatilization," "thermal
				stripping," and "soil roasting," means the ex-situ technology that uses heat to
				physically separate contaminants from excavated soil. Vaporized hydrocarbons
				may require treatment in a secondary treatment unit, such as an afterburner,
				prior to atmospheric discharge.
21.
				"New facility" means those treatment facilities not in place and operating on
				the effective date of this regulation.
22. "Off-site" means a location other than
				the property on which the contamination of the soil occurred and any contiguous
				property under the same ownership.
23. "On-site" means the property on which the
				contamination of the soil occurred and all contiguous property under the same
				ownership.
24. "Open-dumping" means
				any unpermitted solid waste disposal activity.
25. "Owner/operator" means the person who
				owns the land on which a solid waste management facility is located or the
				person who is responsible for the overall operation of the facility, or both.
25. "PAH" means polynuclear
				aromatic hydrocarbons
26. "Person"
				means an individual, corporation, company, association, partnership, unit of
				local government, state agency, federal agency, or other legal
				entity.
27. "Prepared beds" means a
				contained area above ground where soil can be tilled or variously manipulated
				to increase biological treatment, i.e., contained land farming.
28. "RD&D Permit" means a research,
				development and demonstration permit issued pursuant to R.61-107.10.
29. "Residence" means any structure, all or
				part of which is designed or used for human habitation, that has received a
				final permit for electricity, permanent potable water supply, permanent sewage
				disposal, and a certificate of occupancy, if required by the local
				government.
30. "Road base" means
				that portion of road construction which is over-lain with a permanent
				impervious surface.
31. "Shipment"
				means all soil from the same release area.
32. "Soil-like material" means material,
				man-made or naturally occurring, that has good absorption capabilities and is
				used to absorb and bulk solid waste spills, e.g., kaolin clay, bentonite, kitty
				litter, sand, vermiculite.
33.
				"Soil slurry reactor" means biological or chemical treatment of soil by making
				a mixture with water and treating in a contained vessel.
34. "Soil treatment facility" means a
				facility that treats contaminated soil and soil-like material.
35. "Soil venting," means a method to remove
				volatile and semi-volatile contaminants from soil. A positive or negative air
				pressure is applied either passively or actively to soil to remove vapors which
				are appropriately treated.
36.
				"Soil washing" means an ex-situ process to mechanically scrub soil to remove
				contaminants. Soft particles are separated from soil in an aqueous-based
				system. The wash water may be augmented with leaching agents, surfactants, pH
				adjustment or chelating agents.
37.
				"TCLP" means Toxicity Characteristic Leaching Procedure, a laboratory test used
				to determine if a substance is a hazardous waste due to leachability. The TCLP
				(Method 1311) is published in "Test Methods for Evaluating Solid Waste,

				reference in R.61-79.260.11.

				"TPH" means total petroleum hydrocarbons.
39. "Treatment" means the off-site
				manipulation of contaminated soil in a confined and regulated environment to
				bring the soil into compliance with standards established in this
				regulation.
40. "Used Oil" means
				any oil that has been refined from crude oil or synthetic oil that has been
				used, and as a result of such use is contaminated by physical or chemical
				impurities.

42. "Waste profile sheet" means a form filled
				out by the waste generator outlining specific information regarding the
				generator, generator's site location, generating process information, and a
				full waste characterization. This includes describing the chemical and physical
				(solid, liquid, or gas) characteristics of the solid waste, a description of
				the waste including a list of the chemical contaminants in the waste,
				analytical testing certification, quantity, and container size for proper
				disposal. The generator shall submit the waste profile sheet to the treatment
				facility for approval prior to shipment of soil pursuant to this
				regulation.
43. "Weathered oil"
				means oil that has been exposed to leaching and low-level biodegradation or
				biotransformation and soil chemical reactions for extended periods of time,
				resulting in a contaminant chemical composition that is no longer virgin
				oil.
