    1. Introduction


A. Scope

  1. The present general technical guidelines provide guidance for the environmentally sound management (ESM) of wastes consisting of, containing or contaminated with persistent organic pollutants (POPs), pursuant to decisions IV/17, V/26, VI/23, VII/13 and VIII/16 of the Conference of the Parties to the Basel Convention on the Control of Transboundary Movement of Hazardous Wastes and Their Disposal, I/4, II/10, III/8, IV/11 and V/12 of the Open-ended Working Group of the Basel Convention, resolution 5 of the Conference of Plenipotentiaries to the Stockholm Convention on Persistent Organic Pollutants, decisions INC-6/5 and INC-7/6 of the Intergovernmental Negotiating Committee for an International Legally Binding Instrument for Implementing Action on Certain Persistent Organic Pollutants and decisions SC-1/21and SC-2/6 of the Conference of the Parties to the Stockholm Convention.

  2. Specific technical guidelines on wastes consisting of, containing or contaminated with the following categories of POPs have been developed:

(a) Polychlorinated biphenyls (PCBs); this technical guideline also covers polychlorinated terphenyls (PCTs) and polybrominated biphenyls (PBBs), which are subject to the Basel Convention but are not POPs subject to the Stockholm Convention;

(b) The pesticide POPs aldrin, chlordane, dieldrin, endrin, heptachlor, hexachlorobenzene (HCB),1 mirex and toxaphene, and HCB as an industrial chemical;

(c) 1,1,1-Trichloro-2,2-bis(4-chlorophenyl)ethane (DDT);

(d) Unintentionally produced polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), HCB and PCBs.

  1. The guidance provided within this document is intended to serve as a stand-alone general guidance and also as what might be termed an “umbrella” guide to be used in conjunction with the specific technical guidelines.

  2. To these ends, the present general technical guidelines provide:

  1. General guidance on the management of wastes consisting of, containing or contaminated with POPs; and

  2. A framework for addressing issues referred to in Article 6, paragraph 2 of the Stockholm Convention (see subsection II.B.2 of the present guidelines on waste related provisions of the Stockholm Convention).

  1. Considerations pertaining to the environmentally sound disposal of wastes consisting of, containing or contaminated with POPs discussed in these guidelines include pre-treatment since it may be important when determining the disposal method. The guidelines also provide guidance on reducing or eliminating releases to the environment from waste disposal and treatment processes.

  2. It should be noted that guidance on best available techniques (BAT) and best environmental practices (BEP) as they apply to the prevention or minimization of the formation and release of unintentional POPs from the anthropogenic sources listed in Annex C of the Stockholm Convention is provided by the Stockholm Convention. It should also be noted that there are draft guidelines on best available techniques and provisional guidance on best environmental practices relevant to Article 5 and Annex C of the Stockholm Convention on Persistent Organic Pollutants. Those guidelines were finalized by the Stockholm Convention Expert Group on Best Available Techniques and Best Environmental Practices in November 2006. A final version of the guidelines is expected to be adopted by the Conference of the Parties of the Stockholm Convention at its third meeting, in 2007.

B. About POPs2

  1. Most of the quantities of POPs are of anthropogenic origin. For some POPs, such as those listed in Annex C of the Stockholm Convention, some quantities are also generated by natural processes.

  2. The characteristics of POPs (toxicity, persistence and bioaccumulation), the potential for their long range transport, and their ubiquitous presence throughout the world in ecosystems and in humans were the impetus for the creation of the Stockholm Convention. As well, as noted in chapter II, section A, subsection 2 below, wastes consisting of, containing or contaminated with POPs are listed as wastes in Annexes I and VIII of the Basel Convention.

  3. Improper treatment or disposal of a waste consisting of, containing or contaminated with POPs can lead to releases of POPs. Some disposal technologies can also lead to the unintentional formation and release of POPs.
