Dense Slurry Coal Ash Management: Full Compliance, Lower Cost, Less Risk

摘要

The Environmental Protection Agency's (EPA) newly enacted Coal Combustion Residuals (CCR) rules and proposed Effluent Limitations Guidelines (ELG) will significantly impact waste management practices in the coal-fired power industry. The new rules will regulate fly ash settling ponds out of existence; regulate the location, design, operation, and closure requirements for impoundments; and impose new requirements for wastewater. Traditional "dry ash" management techniques satisfy the rules' proposed requirements, but they suffer from inherent technical deficiencies and pose prohibitive costs.
