M/395 - Waste

This Technical Report gives additional and specific information on sampling for testing of waste from the extractive industry to support the development of appropriate sampling plans. This supplementary guidance to EN 14899 is required because waste from the extractive industry differs considerably from the waste types and sampling scenarios covered in the existing technical reports (CEN/TR 15310-1 to -5) that support the Framework Standard. This guidance document should be used in conjunction with EN 14899 and its supporting technical reports CEN/TR 15310-1 to -5. The approach to sampling described in this document is primarily focused on the requirements to undertake mineralogical and geochemical testing of the waste. Whilst much of the background information provided is also relevant to geotechnical investigations there may be important additional requirements or differences in approach for determining relevant physical parameters. For example, many geotechnical parameters are determined using field tests, which are not discussed in this document. References to alternative source documentation are provided. The guidance provided in this document applies only to above-ground exposure to radio-nuclides present in the undisturbed earth crust and not to the production, processing, handling use, holding, storage, transport, or disposal of radioactive substances that are or have been processed for their radioactive, fissile or fertile properties. This Technical Report provides some discussion of current best practice, but is not exhaustive. To clarify the text, the document provides a number of worked examples in the Annexes.

This Technical Report gives guidance and recommendations on the application of methods for the
characterization of waste from extractive industries (as defined in Article 2 of Directive 2006/21/EC) , i.e. wastes resulting from the prospecting, extraction, treatment and storage of mineral resources and the working of quarries. The document covers characterization methods for both physical and geochemical properties and also other significant aspects, from planning to interpretation and reporting. The main purpose of the document is to aid the extractive industry and regulatory agencies in the member states in understanding how to perform waste characterization for planned, active and closed extractive operations. The document includes a discussion on when and why characterization may be needed and on the contexts within which characterization data may need to be applied. However, it does not cover information on how to apply these characterization results, e.g. for dam design or closure planning. For guidance on how to use characterization results correctly for predictive modelling or design purposes references are made to other sources of information. The extractive industry covers many different sectors with very different waste categories and characterization may be carried out with many different objectives. For this reason, a guidance document on characterization cannot be prescriptive or provide generally applicable instructions on how waste characterization should be performed in each and every case.

This European standard specifies methods to determine the potential of sulfide bearing materials for the formation of acidic drainage. Specified are methods for determining both the acid potential (AP) and the neutralisation potential (NP) of the material. From these results the net neutralisation potential (NNP) and the neutralisation potential ratio (NPR) are calculated. This European standard is applicable to all sulfide bearing wastes from the extractive industries excluding wastes which will have pH < 2 in the initial step of the procedure described in 8.2.3.

This Technical Report describes the performance and evaluation of kinetic tests for sulfidic waste material that, according to previous testing (primarily acid base accounting), is likely to go acidic or when the result of such testing is inconclusive. This Technical Report also covers the issue of drainage from sulfidic material that is likely to be well buffered but that will produce a neutral drainage potentially affected by sulfide mineral oxidation. This Technical Report will not include aspects of sampling and testing that are already covered in the overall guidance document for characterisation of extractive waste (CEN/TR 16376) or in the guidance document on sampling of wastes from extractive industries (CEN/TR 16365).
