The enactment of RCRA was influenced by the need to manage which type of materials?

The Resource Conservation and Recovery Act (RCRA) was enacted primarily to manage hazardous materials. This legislation was designed to ensure the proper management, treatment, storage, and disposal of hazardous waste in the United States. The emphasis on hazardous materials stems from the potential dangers they pose to human health and the environment, including their ability to cause pollution, health risks, and long-term ecological damage if not managed correctly.

The RCRA provides a framework for States to develop waste management programs that can protect the public and the environment from the hazards associated with waste. It also established "cradle-to-grave" regulations for hazardous waste, which means that the management of these materials must be tracked from their generation to their ultimate disposal. This legislation demonstrates a significant shift in environmental policy, focusing on reducing waste and promoting recycling and resource recovery.

Understanding the significance of this act helps underscore the importance of proper hazardous materials management in preventing environmental contamination and ensuring public safety.
