Final answer:
The law that bans the disposal of hazardous waste in landfills and requires incineration is the Resource Conservation and Recovery Act (RCRA), which was enforced by the EPA and amended in 1984.
Step-by-step explanation:
The law you are referring to that banned the disposal of hazardous waste in landfills and required that waste to be incinerated, enforced by the Environmental Protection Agency (EPA) and amended in 1984, is the Resource Conservation and Recovery Act (RCRA).
This act set up a framework for the proper management of hazardous waste to ensure that it is managed safely from 'cradle to grave,' which includes the creation, transportation, treatment, storage, and disposal of hazardous waste. This was a crucial step in hazardous waste regulation, considering the importance of both resource conservation and the protection of human health and the environment.
The RCRA helped to establish a comprehensive regulatory program which affected how hazardous waste was handled across the nation. The act was instrumental in moving the management of hazardous waste towards methods such as recycling, treatment, and the controlled use of incinerators, significantly contributing to the conservation of resources and the mitigation of environmental health risks related to improper waste management.
