Question

which of the following laws established the environmental protection agency (epa) to enforce federal laws that involve the environment?
the american recovery and reinvestment act (2009)
the resource conservation and recovery act (1984)
the resource recovery act (1970)
the national environmental policy act (1970)

Explanation:

The National Environmental Policy Act (NEPA) of 1970 was a significant piece of environmental legislation. It was one of the first laws to address environmental protection at the federal level in the United States. While it didn't directly "create" the EPA in the sense of being the sole law for its establishment, NEPA was a foundational environmental law passed in 1970. The EPA was established in 1970 as well, and NEPA was part of the broader environmental regulatory push that led to the creation of the EPA to enforce environmental - related federal laws.
The American Recovery and Reinvestment Act (2009) was mainly about economic stimulus. The Resource Conservation and Recovery Act (1984) was focused on waste management (especially hazardous waste). The Resource Recovery Act (1970) was more about solid waste management and resource recovery from waste, not the overall enforcement of environmental laws which is the EPA's main role.

Answer:

The National Environmental Policy Act (1970)
