Any deliberate mixing of prohibited hazardous waste with soil that changes its treatment classification (i.e., from waste to contaminated soil) is riot allowed under the dilution prohibition in section 66268.3 of this division. "Soil -pore liquid" means the liquid contained in openings between particles of soil in the unsaturated zone "Solid Waste Management Unit" means any unit at a hazardous waste facilityfrom which hazardous constituents might migrate, irrespective of whether the units were intended for the management of wastes, including but not limited to: containers, tanks, surface impoundments, waste piles, land treatment units, landfills, incinerators and underground injection wells. "Soluble threshold limit concentration" or "STLC" means the concentration of a solubilized and extractable bioaccumulative or persistent toxic substance which, if equaled or exceeded in a waste or waste extract determined pursuant to Appendix II of chapter 11 of this division renders the waste hazardous. "Sorb" means to either adsorb or absorb, or both. "Sorbent" means a material that is used to soak up free liquids by either adsorption or absorption, or both. See also "Sorb".

"Sump" means any pit or reservoir that meets the definition of tank and those troughs/trenches connected to it that serve to collect hazardous waste for transport to hazardous waste storage, treatment, or disposal facilities; except that as used in the landfill, surface impoundment, and waste pile rules, "sump" means any lined pit or reservoir that serves to collect liquids drained from a leachate collection and removal system or leak detection system for subsequent removal from the system. "Surface impoundment" or "impoundment" means a facility or part of a facility which is a natural topographic depression, man-made excavation or diked area formed primarily of earthen materials (although it may be lined with man-made materials), which is designed to hold an accumulation of liquid wastes or wastes containing free liquids, and which is not an injection well. Examples of surface impoundments are holding, storage, settling, and aeration pits, ponds and lagoons. "Surge control tank" means a pipe or storage reservoir sufficient in capacityto contain the surging liquid discharge of the process tank to which it is connected. "Surplus material" means an unused raw material or commercial product obtained by a person who intended to use or sell it, but who no longer needs it, and who transfers ownership of it to another person for use in a manner for which the material or product is commonly used.
