Answer: (A)

NPDES stands for National Pollutant Discharge Elimination System. This program was established under the Clean Water Act to regulate discharges of pollutants into the waters of the United States. The NPDES permits are essential for controlling water pollution and ensuring that wastewater treatment facilities and other discharge sources adhere to specific standards for environmental protection. By requiring permits, the NPDES ensures that pollutants are managed in a way that protects water quality and aquatic ecosystems, thereby contributing to public health and environmental safety. This regulatory framework is crucial for maintaining the integrity of the nation’s water resources.
