ABSTRACT:
This report reviews legislation which affects the management of coal-use residues in IEA Coal Research member countries. In the past, disposal of residues was not considered a problem in many countries.

Greater environmental awareness has resulted in increasingly stringent legislation to control all aspects of coal utilisation, including disposal and utilisation of residues. Water pollution caused by leaching is the primary concern associated with residues.

Legislation developed in one country frequently becomes the model for policy in other nations. The report examines the approach towards legislation in IEA Coal Research member countries, and considers the following aspects:

  • the sources and types of residues and disposal issues;
  • Ieaching tests and their limitations;
  • Iegislation used to classify residues for disposal;
  • regulations and guidelines concerned with handling and disposal practices; and
  • regulations that affect utilisation options.

The utilisation of coal inevitably produces large quantities of residues. Most residues from coal combustion and utilisation are considered non-hazardous under current disposal legislation. However, residues from some combustion technologies and some types of FGD residue may require special consideration before disposal is allowed. The successful management of coal-use residues requires knowledge of the legislative constraints that control the use and disposal of such materials in various countries.
