Treatment

Definition(s)

Treatment

Treatment―as applied to Type A Facilities (defined herein), excluding Transfer Stations, treatment shall be defined as any method, technique, or process capable of hanging the physical and/or chemical characterization or composition of E and P Waste so as to reclaim salvageable hydrocarbons, process reusable material, reduce waste volume (volume reduction), neutralize waste, reduce §549 criteria concentration(s) or otherwise render the waste more suitable for handling, storage, transportation, and/or disposal.

Treatment

Any method, technique, or process, including neutralization, designed to change the physical, chemical, or biological character or composition of any hazardous waste so as to neutralize such waste, to recover energy or material resources from the waste, or to render such waste non-hazardous or less hazardous, safer to transport, store, or dispose of, amenable for recovery or storage, or reduced in volume. The term does not include any activity that might otherwise be considered treatment that is exempt from regulation under this section (such as neutralization of caustic or acidic fluids in an elementary neutralization unit).

Treatment Zone

Treatment Zone

Definition(s)

Treatment Zone

Treatment Zone―the soil profile in a land treatment cell that is located wholly above the saturated zone and within which degradation, transformation, or immobilization of E and P Waste constituents occurs. The treatment zone is subdivided as follows.
  1. Waste Treatment Zone (WTZ)―the active E and P Waste treatment area consisting solely of the E and P Waste solids applied to a land treatment cell during the application phase, exists entirely above grade (original cell bottom), and whose actual depth depends on the solids content of the E and P Waste applied. For monitoring purposes the WTZ represents the 0-24" depth increment.
  2. Upper Treatment Zone (UTZ)―the E and P Waste/native soil (original cell bottom) interface in a land treatment cell where some disturbance occurs as a result of E and P Waste treatment/manipulation. For monitoring purposes, the UTZ represents the 24-36" depth increment.
  3. Lower Treatment Zone (LTZ)―the zone beneath the UTZ in a land treatment cell from approximately 36-54" (or to the top of the subsurface drainage system) which remains undisturbed throughout the life of a land treatment cell.

Underground Source of Drinking Water (USDW)

An aquifer or its portion which supplies any public water supply system or currently supplies drinking water for human consumption or which contains sufficient water to supply a public water system or has a total dissolved solids (TDS) concentration of less than 10,000 mg/l. The EPA may exempt an aquifer if it will not serve as a source of drinking water in the future because it is economically or technically impractical to recover the water or to render it fit for human consumption or because the aquifer produces or is expected to commercially produce minerals, hydrocarbons, or geothermal energy. While the EPA defines a USDW as containing less than 10,000 mg/l TDS, certain states, such as California and Texas, have adopted a producing and injection well surface pipe protection standard for fresh water aquifers that contain less than 3,000 mg/l TDS.
