At what temperature threshold should wastes be discharged into a cooling basin?

• A. 100 Degrees Fahrenheit
• B. 120 Degrees Fahrenheit
• C. 140 Degrees Fahrenheit
• D. 180 Degrees Fahrenheit

Answer: (C)

Hot waste needs to be cooled before it’s discharged to protect aquatic life and downstream equipment, and a cooling basin serves that purpose by letting the heat dissipate before final release. The set point of 140 degrees Fahrenheit is used as the trigger: once waste reaches this temperature, it should be routed to a cooling basin to bring the temperature down prior to discharge. Lower temperatures like 100 or 120 degrees are already within safe discharge ranges and don’t require routing to cooling basins, while a much higher temperature such as 180 degrees would clearly demand cooling too, but the defined threshold used in practice is 140.
