1. "Aerobic" means able to live, grow, or take place only when free oxygen is present.

5. "BTEX" means the total chemical constituents benzene, toluene, ethyl benzene, and total xylenes.

6. "Chemical oxidation" means a chemical reaction that increases the oxygen content in a compound or a reaction in which an element or ion loses electrons, resulting in a more positive valence.

7. "Class I soil" means soil contaminated with one or more of the following contaminants: gasoline, jet fuels, diesel fuels, kerosene, distillate fuel oils (number one and number two fuel oils), and other contaminants as approved by the Department for this classification.

8. "Class II soil" means soil contaminated with one or more of the following contaminants: combination fuel oils (number three and number four fuel oils), residual fuel oils (number five and number six fuel oils), virgin lubricating oils, used oils, weathered oils, other petroleum based products not listed in Class I, and other contaminants as approved by the Department for this classification.

9. "Class III soil" means soil contaminated with any contaminant other than those listed under Class I or Class II.

10. "Composting" means treatment of contaminated soil by aerobic biodegradation of contaminants in an above ground, contained, or uncontained environment.

11. "Contaminated soil" means soil and soil-like material containing contaminants at a concentration that the Department has deemed poses a potential threat to human health and/or the environment and that does not constitute a hazardous waste, as defined by RCRA, the SCHWMA, and the Regulations promulgated pursuant thereto, as amended.

12. "Department" means the South Carolina Department of Health and Environmental Control.

13. "Existing facility" means those facilities in place and operating on the effective date of this regulation.

14. "Ex-situ" means the 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, Physical/Chemical Methods," EPA Publication SW-846, as incorporated by reference in R.61-79.260.11.

38. "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.

41. "Virgin oil" means oil that has never been used or weathered.

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.
