Which entities can be considered a 'Person' under the Clean Water Act?

• A. Governments at any level
• B. Only individuals and corporations
• C. Only private businesses
• D. Only state governments

Answer: (A)

The question tests how broadly the Clean Water Act defines the term “person.” In the CWA, “person” is not limited to individuals or private companies. The statute uses a broad definition that includes individuals, corporations, municipalities, states, and the United States government or its agencies or instrumentalities. This broad definition matters because the Act’s permit and enforcement mechanisms—such as who must obtain NPDES permits and who can be held liable for violations—apply to any entity that falls under that definition. Since governments at federal, state, and local levels can own or operate point sources and agencies can act as polluters or permittees, they are considered “persons” under the Act. That’s why the option stating governments at any level is the best answer.

The other choices are too narrow because they exclude important categories that the statute includes, such as government entities, federal or local agencies, or public authorities, which can all be subject to the Act’s requirements as “persons.”
