Which regulatory agency sets the minimum manhole cover diameter as specified in 2008?

• A. TCEQ
• B. EPA
• C. OSHA
• D. DOT

Answer: (A)

The requirement is set by the regulator responsible for state wastewater facility design. In Texas, that is the Texas Commission on Environmental Quality (TCEQ). TCEQ develops and enforces the design criteria for municipal wastewater systems, including details like the minimum manhole cover diameter referenced in 2008. This kind of specification ensures consistent access, safety, and maintenance across systems.

The other agencies regulate different areas: EPA handles federal environmental protections, OSHA focuses on workplace safety, and DOT deals with transportation safety. None of them prescribe specific manhole dimensions for Texas wastewater infrastructure, which is why the regulatory body in this question is TCEQ.
