NPDES stands for which system?

• A. National Pollutant Discharge Elimination System
• B. National Pollution and Discharge Emission System
• C. National Program for Discharge and Erosion
• D. National Pollutant Disposal and Emission System

Answer: (A)

NPDES is the permit system under the Clean Water Act that regulates discharges of pollutants into waters of the United States. The full form stands for National Pollutant Discharge Elimination System, which reflects the program’s purpose: to control and limit pollutant discharges through permits. The other wording doesn’t fit the official name—“Emission” would be more about air releases, and “Erosion” or “Disposal” don’t describe this water-permit framework. In practice, projects like construction sites use NPDES permits to manage sediment and erosion in runoff, linking the acronym directly to how we protect water quality from discharges.
