Which state agency has authority over environmental matters, including regulation of wastewater systems?

• A. TWDB
• B. TDEQ
• C. TCEQ
• D. TDHHS

Answer: (C)

In Texas, environmental regulation, including oversight of wastewater systems, is handled by the Texas Commission on Environmental Quality. This agency issues permits for wastewater treatment facilities, regulates discharges to surface and groundwater, enforces water quality standards, and runs programs that address pretreatment for industrial users. It also works with the federal EPA to implement state and national environmental rules.

The other options serve different purposes: the Texas Water Development Board focuses on planning and funding water infrastructure, not regulation; the Texas Department of Health and Human Services handles public health programs rather than wastewater regulation. The environmental regulatory authority in Texas is the Texas Commission on Environmental Quality.
