Which regulation is crucial for managing industrial stormwater discharge?

The Clean Water Act is the primary regulation that governs the management of industrial stormwater discharge. This act aims to restore and maintain the integrity of the nation's waters by preventing point source pollution, which includes discharges from identifiable sources such as industrial facilities. Under this act, facilities that discharge stormwater associated with industrial activity are required to obtain a National Pollutant Discharge Elimination System (NPDES) permit, ensuring they follow specific guidelines and practices to minimize pollution.

The other regulations listed serve different purposes. The Resource Conservation and Recovery Act focuses on the management of hazardous waste, while the National Environmental Policy Act requires federal agencies to assess the environmental impact of their proposed actions. The Endangered Species Act is aimed at the conservation of threatened and endangered plants and animals and their habitats. Hence, while all these laws are important for environmental protection, the Clean Water Act is specifically integral to addressing industrial stormwater discharges.
