The U.S. Environmental Protection Agency (EPA) encourages the use of coal combustion products (CCPs) in highway construction projects such as in concrete, road base, embankments, flowable fill, and other beneficial applications. The increased use of these materials, which would otherwise be discarded as waste, can reduce greenhouse gases in the atmosphere, reduce energy consumption, and conserve natural resources. Some applications, such as road embankments and other non-encapsulated (loose) uses, may require the evaluation of local hydrogeological conditions to ensure protection of human health and the environment. To encourage the increased use of coal combustion products, EPA, the Department of Energy, and the Federal Highway Administration, along with the American Coal Ash Association and the Utility Solid Waste Activities Group, are co-sponsoring the Coal Combustion Products Partnership (C2P2). The purpose of C2P2 is to foster the beneficial uses of coal combustion products. This booklet is intended to help users and the public understand both the environmental benefits and potential impacts of using coal combustion products in various applications. EPA and the National Academy of Sciences are evaluating the use of coal combustion products as mine-fill and will address this issue separately.
