A. Low POP content
(a) Disposal of wastes with a high POP content, including waste stockpiles, should be a priority;
(b) Availability of treatment capacity;
(c) Limit values within national legislation are relevant;
(d) Availability of analytical methods; and
(e) Lack of knowledge and data;
the following provisional definitions for low POP content should be applied:
(a) PCBs: 50 mg/kg;9
(b) PCDDs and PCDFs: 15 g TEQ/kg;10
(c) Aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, HCB, mirex and toxaphene: 50 mg/kg for each.11
B. Levels of destruction and irreversible transformation
(a) Both destruction efficiency12 (DE) and destruction removal efficiency13 (DRE) are a function of the initial POP content and do not cover formation of unintentionally produced POPs during destruction or irreversible transformation;
(b) DE is an important criterion for helping to assess technologies for destruction and irreversible transformation, but can be difficult to measure in a reproducible and comparable manner, especially on a regular basis;
(c) DRE considers only emissions to air;
(d) BAT and BEP set safe design and operating conditions, including expected destruction efficiencies, in particular circumstances on a technology by technology basis;
(e) BAT and BEP have not been identified for all disposal methods;
(f) Existence of pertinent national legislation and international rules, standards and guidelines;
(g) Lack of knowledge and data;
The following provisional definition for levels of destruction and irreversible transformation, based upon absolute levels (i.e., waste output streams of treatment processes) should be applied:
(a) Atmospheric emissions:
PCDDs and PCDFs: 0.1 ng TEQ/Nm3;14
All other POPs: pertinent national legislation and international rules, standards and guidelines, examples of pertinent national legislation can be found in annex II;
(b) Aqueous releases: pertinent national legislation and international rules, standards and guidelines, examples of pertinent national legislation can be found in annex II;
(c) Solid residues: POP contents should be below the low POP contents defined in section A above of this chapter. However, if the POP content of unintentionally produced PCDD/PCDFs is above the low POP content defined in section A, the solid residues should be treated in accordance with section IV.G.
In addition, technologies for destruction and irreversible transformation should be operated in accordance with BAT and BEP.
C. Methods that constitute environmentally sound disposal
