All waste generators must ensure that the waste they generate is classified in accordance with SANS 10234. Generators of hazardous waste must ensure that a safety data sheet for the hazardous waste is prepared in accordance with SANS 10234.

The main impact of the new NEMWA waste regulations is that mining waste (residues and deposits), which was previously exempt from the waste classification system, is now classified as a “waste”’ according the new waste classification and management regulations. This means that mining waste now has to be disposed of at a facility which complies with the NEMWA Norms and Standards which sets out the barrier requirements for the various types of waste.

The result will be that all waste or by-products which includes mining deposits and residues must be classified according to the regulations, irrespective of the potential impact or lack of impact on the water resources. The classification of the waste will determine the barrier requirements of a facility for that specific type of waste.

The scope of work for a Waste Classification will entail the following:

  • Sampling, Analysis and Assessment of Waste Type
    • Analysing and classification of samples according to waste classification regulations and assessment done in accordance with the National Norms and Standards for the Assessment of Waste for Landfill Disposal (GN 635 of 23 August 2013)
  • Recommended methods of disposal

      GCS will recommend the appropriate method of disposal and the type of facility to be used for the disposal of waste. This barrier design recommendation for the disposal facility will be done in accordance with the National Norms and Standards for the Disposal of Waste to Landfill (GN 636 of 23 August 2013)

  • Development of Material Safety Data Sheet (MSDS) as described in SANS 10234 which will include:
    • Source and Composition of Waste
    • Hazardous Identification
    • Physical and chemical properties
    • Toxicological and ecological effects
    • Transport
    • Disposal options
    • First aid/firefighting measures
    • Handling and storage
  • Development of Manifest System
    • A standard waste manifest document will be developed for use by the client to ensure safe handling of waste from generation to end disposal.
  • Compilation of report
    • A Classification report with recommendations will be compiled and will include the supporting documents as mentioned in the above tasks i.e. original laboratory results
