2009/360/EC: Commission Decision of 30 April 2009 completing the technical requirements for waste characterisation laid down by Directive 2006/21/EC of the European Parliament and of the Council on the management of waste from extractive industries (notified under document number C(2009) 3013)

• CELEX: Directive 2006/21/EC
• Articles: 4

Article 1 Waste characterisation

1.   Member States shall ensure that the waste characterisation to be carried out by operators in the extractive industries complies with this Decision.

2.   Waste characterisation shall cover the following categories of information as specified in the Annex:

(a)

background information;

(b)

geological background of deposit to be exploited;

(c)

nature of the waste and its intended handling;

(d)

geotechnical behaviour of the waste;

(e)

geochemical characteristics and behaviour of the waste.

3.   The criteria for defining inert waste laid down in Decision 2009/359/EC shall be taken into account for the purpose of assessing the geochemical behaviour of waste. Where, on the basis of those criteria, waste is considered to be ‘inert’, it shall be only subject to the relevant part of geochemical testing referred to in point 5 of the Annex.

Article 2 Collection and evaluation of information

1.   Information and data necessary for the waste characterisation shall be collected in the order set out in paragraphs 2 to 5.

2.   Existing investigations and studies, including existing permits, geological surveys, similar sites, lists of inert waste, appropriate certification schemes, European or national standards for similar material, which satisfy the technical requirements set out in the Annex shall be used.

3.   The quality and representativity of all information shall be evaluated and possible missing information shall be identified.

4.   Where information necessary for the characterisation of the waste is missing, a sampling plan shall be drawn up in accordance with standard EN 14899 and samples shall be taken in accordance with that sampling plan. Sampling plans shall be based on identified information as necessary, including:

(a)

purpose of data collection,

(b)

testing programme and sampling requirements,

(c)

sampling situations, including sampling from drill-cores, excavation face, conveyor belt, heap, pond, or other relevant situation,

(d)

procedures and recommendations for sample numbers, size, mass, description and handling.

The reliability and quality of the sampling results shall be evaluated.

5.   The results of the characterisation process shall be evaluated. Where necessary, additional information shall be collected following the same methodology. The final result shall feed into the waste management plan.

Article 3

This Decision is addressed to the Member States.

ANNEX

ANNEX

TECHNICAL REQUIREMENTS FOR WASTE CHARACTERISATION

1.    Background information

Review and understanding of the general background and objectives of the extractive operation.

Collection of general information about:

—

prospecting, extraction, or processing activity,

—

type and description of method of extraction and process applied,

—

nature of the intended product.

2.    Geological background of deposit to be exploited

Identification of the waste units to be exposed by extraction and processing by providing relevant information on:

—

nature of surrounding rocks, their chemistry and mineralogy, including hydrothermal alteration of mineralised rocks and barren rocks,

—

nature of deposit, including mineralised rocks or rock-bearing mineralisation,

—

mineralisation typology, their chemistry and mineralogy, including physical properties such as density, porosity, particle size distribution, water content, covering worked minerals, gangue minerals, hydrothermal newly-formed minerals,

—

size and geometry of deposit,

—

weathering and supergene alteration from the chemical and mineralogical point of view.

3.    The waste and its intended handling

Description of the nature of all the wastes occurring in each prospecting, extraction and processing operation, including overburden, waste rock and tailings, by providing information on the following elements:

—

origin of the waste in the extraction site and the process generating that waste such as prospecting, extraction, milling, concentration,

—

quantity of the waste,

—

description of the waste transport system,

—

description of the chemical substances to be used during treatment,

—

classification of the waste according to Commission decision 2000/532/EC  ( 1 ) , including hazardous properties,

—

type of intended waste facility, final form of exposure of the waste and method of deposition of the waste into the facility.

4.    Geotechnical behaviour of waste

Identification of the suitable parameters for assessing the intrinsic physical characteristics of the waste taking into account the type of waste facility.

Relevant parameters to be considered are: granulometry, plasticity, density and water content, degree of compaction, shear strength and angle of friction, permeability and void ratio, compressibility and consolidation.

5.    Geochemical characteristics and behaviour of the waste

Specification of the chemical and mineralogical characteristics of the waste, and of any additives or residuals remaining in the waste.

Prediction of drainage chemistry over time for each type of waste, taking into account its intended handling, in particular:

—

evaluation of metals, oxyanion and salt leachability over time by pH dependence leaching test, and/or percolation test and/or time-dependent release and/or other suitable testing,

—

for sulphide-containing waste, static or kinetic tests shall be carried out in order to determine acid-rock drainage and metal leaching over time.
