THE COUNCIL,

HAVING REGARD to Article 5 a) of the Convention on the Organisation for Economic Co-operation and Development of 14 December 1960;

HAVING REGARD to the Decision-Recommendation of the Council of 1 February 1984 on Transfrontier Movements of Hazardous Waste [C(83)180(Final)];

HAVING REGARD to the Decision-Recommendation of the Council of 5 June 1986 on Exports of Hazardous Wastes from the OECD Area [C(86)64(Final)];

HAVING REGARD to the Resolution of the Council of 20 June 1985 on International Co-operation Concerning Transfrontier Movements of Hazardous Wastes, by which it has been decided to develop an international system for effective control of transfrontier movements of hazardous wastes [C(85)100];

CONVINCED that the development of such a system requires a clear delineation of the wastes to be included in the system;

On the proposal of the Environment Committee;

I. DECIDES that for the purpose of implementing the above-mentioned Council Acts on the control of transfrontier movements of hazardous wastes involving any Member country:

a) The terms "wastes" and "disposal" shall be defined as specified in the Annex, which is an integral part of this Decision;

b) Those wastes which are referred to in the above-mentioned Council Acts as Hazardous Wastes shall consist of:

i) A core list of wastes as specified in the Annex; and

ii) All other wastes which are considered to be or are legally defined as hazardous wastes in the Member country from which these wastes are exported or in the Member country into which these wastes are imported¹;

c) Member countries shall ensure that the wastes subject to control are classified in the manner specified in the Annex unless these wastes are subject to a transfrontier movement which takes place entirely among the parties to a bilateral or multilateral agreement or arrangement specifying a different method of classification².

II. DECIDES that the definitions of Waste and Hazardous Waste contained in the above-mentioned Council Acts are hereby repealed.

III. INSTRUCTS the Environment Committee:

a) To take account of this Decision in developing the draft international agreement referred to in the Resolution on International Co-operation Concerning Transfrontier Movements of Hazardous Wastes [C(85)100];

b) To report to the Council after an appropriate period not exceeding three years on the implementation of this Decision and to make any proposals it deems necessary for revisions of the Annex in the light of experience gained in its implementation.

Annex

A series of seven tables serves to define and classify the wastes to be controlled when subject to transfrontier movements. The tables cover the following:

Table Y Core List of Wastes to be Controlled

Table 1 Reasons why Materials are intended for Disposal

Table 2 Disposal Operations

Table 3 Generic Types of Potentially Hazardous Wastes

Table 4 Constituents of Potentially Hazardous Wastes

Table 5 List of Hazardous Characteristics

Table 6 Activities which may generate Potentially Hazardous Wastes

Definitions

For the purposes of this Decision:

1. WASTES are materials other than radioactive materials intended for DISPOSAL, for reasons specified in Table 1.

2. DISPOSAL means any of the operations specified in Table 2.

Core List

For the purposes of this Decision those wastes which belong to any of the categories described in Table Y shall be controlled unless such wastes do not possess any of the hazardous characteristics listed in Table 5.

Classification - International Waste Identification Code

Tables 1 to 6 contain code numbers which, taken together, provide a means of complete characterisation of wastes, through an International Waste Identification Code, in order to facilitate their control from generation to disposal.

The International Waste Identification Code (IWIC) is obtained as follows:

1. Choose the one or at most two major reason(s) why the wastes are intended for disposal from the list in Table 1. Mark down the reason(s) as Q... plus the code number(s).

2. Indicate the method which has been selected for disposal of the wastes by choosing the one operation from Table 2 which most closely describes the fate intended for the wastes. Mark down as D... or R... plus the code number from Table 2.A or Table 2.B as appropriate.

3. Decide whether the wastes are liquid (L), sludge (P) or solid (S). Powders are considered to be solids.

4. Select from Table 3, the one descriptor which most closely describes the generic form of the wastes. Mark down this descriptor as L..., P... or S... plus the code number.

5. Examine Table 4; either the wastes do or do not contain one or more of the constituents listed. If none, mark down as code "CO". If one, mark down the appropriate code number. If more than one, then the best estimate for the group of no more than three entries in terms of descending hazard should be made. This estimate is meant to be qualitative and based upon the best judgment of the generator of the wastes; physical testing is not implied.

6. Select from Table 5 the one or at most two major potential hazard(s) presented by the wastes. Mark down as H... plus the code number(s).

7. Select from Table 6 the most appropriate single activity generating the wastes. Mark down as A... plus the code number.

8. The order of the International Waste Identification Code is the same as Tables 1 through 6. Main heads of the coding system are set off by double oblique lines. Where more than one entry from a specific Table is applicable, the plus sign (+) is used to separate the codes for each such entry:

Q__+__//D,R__//L,P,S__//C__+__+__//H__+__//A__

TABLE 5: LIST OF HAZARDOUS CHARACTERISTICS

(revised May 1994)

Code Number⁶ Characteristics

H1 Explosive: An explosive substance or waste is a solid or liquid substance or waste (or mixture of substances or wastes) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.

H3 Flammable liquids: The word "flammable" has the same meaning as "inflammable". Flammable liquids are liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (for example, paints, varnishes, lacquers, etc. but not including substances or wastes otherwise classified on account of their dangerous characteristics) which give off a flammable vapour at temperatures of not more than 60.50° C, closed-cup test, or not more than 65.60° C, open-cup test. (Since the results of open-cup tests and of closed-cup tests are not strictly comparable and even individual results by the same test are often variable, regulations varying from the above figures to make allowance for such differences would be within the spirit of this definition.)

H4.1 Flammable Solids: Solids, or waste solids, other than those classed as explosives, which under conditions encountered in transport are readily combustible, or may cause or contribute to fire through friction.

H4.2 Substances or Wastes Liable to Spontaneous Combustion: Substances or wastes which are liable to spontaneous heating under normal conditions encountered in transport, or to heating up in contact with air, and being then liable to catch fire.

H4.3 Substances or Wastes which, in Contact with Water Emit Inflammable Gases: Substances or wastes which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities.

H5.1 Oxidizing: Substances or wastes which, while in themselves not necessarily combustible, may, generally by yielding oxygen, cause or contribute to, the combustion of other materials.

H5.2 Organic Peroxides: Organic substances or wastes which contain the bivalent -0-0- structure are thermally unstable substances which may undergo exothermic self-accelerating decomposition.

H6.1 Poisonous (Acute): Substances or wastes liable either to cause death or serious injury or to harm human health if swallowed or inhaled or by skin contact.

H6.2 Infectious substances: Substances or wastes containing viable micro organisms or their toxins which are known or suspected to cause disease in animals or humans.

H8 Corrosives: Substances or wastes which, by chemical action, will cause severe damage when in contact with living tissue, or, in case of leakage, will materially damage, or even destroy, other goods or the means of transport; they may also cause other hazards.

H10 Liberation of toxic gases in contact with air or water: Substances or wastes which, by interaction with air or water, are liable to give off toxic gases in dangerous quantities.

H11 Toxic (Delayed or chronic): Substances or wastes which, if they are inhaled or ingested or if they penetrate the skin, may involve delayed or chronic effects, including carcinogenicity.

H12 Ecotoxic: Substances or wastes which if released present or may present immediate or delayed adverse impacts to the environment by means of bioaccumulation and/or toxic effects upon biotic systems.

H13 Capable, by any means, after disposal, of yielding another material, e.g, leachate, which possesses any of the characteristics listed above.

The potential hazards posed by certain types of wastes are not yet fully documented; objective tests to define quantitatively these hazards do not exist. Further research is necessary in order to develop means to characterise potential hazards posed to man and/or the environment by these wastes. Standardized tests have been derived with respect to pure substances and materials. Many Member countries have developed tests which can be applied to materials destined for disposal by means of operations listed in Table 2 in order to decide if these materials exhibit any of the characteristics listed in Table 5.
