Discharges from industrial users to POTW prohibited by the Clean Water Act are pollutants that tend to cause what hazard?

• A. Fire or explosion hazard in the sewer or POTW
• B. Corrosive damage to pipes
• C. Excessive odor generation
• D. Water discoloration

Answer: (A)

The main idea is that some industrial wastes are ignitable or reactive, and when they’re discharged into a sewer or treatment plant, they can create a fire or explosion hazard. In a POTW, vapors can accumulate, reactive chemicals can ignite, and combustible gases can form in underground sewers or digesters, posing serious danger to workers and to the facility. The Clean Water Act prohibits discharges that tend to cause such fire or explosion hazards to protect people and infrastructure. Corrosive damage to pipes, odors, or discoloration are valid concerns for wastewater systems, but they describe different problems (material damage, nuisance, or aesthetics) rather than the specific fire/explosion hazard highlighted by this prohibition.
