Coal Combustion Residuals

Proposed Rule

EPA is proposing to regulate coal ash to address the risks from the disposal of the wastes generated by electric utilities and independent power producers.

Coal Combustion Residuals (CCR), also referred to as Coal Combustion Products (CCP), are the materials produced primarily from the combustion of coal in coal-fired power plants. CCRs include the following materials:

The characteristics and physical properties of CCRs vary. In general, the size, shape, chemical composition and performance criteria of these materials determines their beneficial reuse as a component of building materials or as a replacement for other virgin materials such as sand, gravel, or gypsum.

Beneficially using CCRs can generate significant environmental, economic, and performance benefits, and provides an excellent example of EPA's Sustainable Materials Management Program implementation.
