Mr. R. Glenn Lunger, PE, Manager Power Market at FLSmidth, Inc. Pneumatic Transport – observed that wet conveying and storage of combustion products appears to be on the brink of extinction with proposed regulation of coal combustion residuals and water usage. There are many considerations that need to be addressed in retrofitted and new dry conveying systems as utilities kick off mitigation projects. FLSmidth has been providing a number of dry pneumatic conveying solutions for combustion products for over 40 years. The costs of the conversion are likely to be only a few million dollars.

EPA Has the Ball by Tom Adams, American Coal Ash Association - Hot Topic Hour January 13, 2011
Tom Adams, Executive Director American Coal Ash Association (ACAA), explains that there is a wide range of opinion on what the impact of a hazardous waste regulation would be on the future of beneficial use of CCP. The agency believes it can exempt preferred beneficial uses from any hazardous waste regulations, and markets for those preferred beneficial uses will be unaffected, at the least, or flourish as generators will invest in technologies to make their CCP more attractive to the end users. In over eighteen months of discussions with CCP marketers, project owners, engineers and architects, contractors, material producers and other stakeholders, the ACAA has determined that the U.S. EPA is wrong in its prediction of market behavior. The stigma of association with hazardous waste regulations and potential liability exposure are primary concerns in the marketplace.

Joshua R. More, Partner Schiff Hardin LLP, described how in working with state regulators a utility was able to close an unlined surface impoundment. Like most states, surface impoundments in Illinois are regulated under groundwater quality rules. These rules provide for protection of groundwater quality and do not specifically address design or closure standards for surface impoundments. The Illinois Environmental Protection Agency initially proposed to regulate the closure of surface impoundments under the landfill rules. However, the landfill rules were promulgated after many of the CCR impoundments in Illinois were built, specifically exclude surface impoundments and include numerous design criteria that are impractical for surface impoundments. Therefore, the utility and its legal team, supported by technical analyses from its environmental consulting team, worked with the state to develop a set of site-specific rules governing closure of a CCR impoundment. The site specific rule has become the model for closing CCR impoundments in the State of Illinois.
