Who must review plans for final approval before a new sewer can be constructed?

• A. county commissioner
• B. city sewer inspector
• C. EPA
• D. water commission

Answer: (C)

Plans for a new sewer are reviewed to ensure federal environmental standards will be met and that the project won’t threaten public health or water quality. The Environmental Protection Agency has the final say to approve such plans, especially when federal funds are involved or the project could affect waters under federal regulation. Local officials like a county commissioner or a city sewer inspector handle funding decisions, permits, and on-site checks, but they don’t grant final construction approval. A water commission usually oversees operation and rates, not plan approvals. So the EPA is the correct agency to give final approval for a new sewer project.
