Which regulation governs the use of fumigants at the federal level?

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is the primary regulation that governs the use of fumigants at the federal level. FIFRA establishes the framework for the registration, distribution, and use of pesticides (which include fumigants) to ensure that they meet safety standards and do not pose unreasonable risks to human health or the environment. This act gives the Environmental Protection Agency (EPA) the authority to regulate pesticide products, including fumigants, by requiring that they be tested for effectiveness and safety before they can be marketed and used.

The other options do not specifically govern the use of fumigants. The Clean Water Act focuses on water quality and pollution control, the National Environmental Policy Act is concerned with environmental assessments and impact statements for federal projects, and the Endangered Species Act is aimed at protecting threatened and endangered species and their habitats. While these laws may intersect with pesticide use, they are not the primary legislation governing fumigants specifically.
