If you are involved with building construction, demolition, or renovation, your company creates construction and demolition (C&D) debris. These materials can consist of three types of waste: (1) Inert or nonhazardous waste; (2) hazardous waste as regulated by the U.S. Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA); and (3) items that contain hazardous components that might be regulated by some states. Most C&D debris is nonhazardous and is not regulated by EPA. Under RCRA, however, if you generate hazardous waste you are required to follow certain procedures when generating, storing, transporting, or disposing of it. In addition, many states have specific definitions of C&D debris that effectively determine what materials are allowed to be disposed of in nonhazardous waste landfills, C&D landfills, or incinerators. Even if federal or state regulations do not apply to your business, you should make efforts to keep the hazardous components of the wastes you generate out of landfills to conserve natural resources and protect human health and the environment. Follow the suggestions outlined in this issue for ways to reduce, reuse, and recycle your waste.
