Is a National Pollutant Discharge Elimination System permit required for projects disturbing an acre or more of land?
No
Yes
Only if in urban areas
Only during certain seasons
The correct answer is: Yes
A National Pollutant Discharge Elimination System (NPDES) permit is indeed required for construction projects that disturb an acre or more of land. This requirement is part of the regulations aimed at controlling water pollution under the Clean Water Act. When a construction site disturbs a significant amount of land, it can lead to stormwater runoff that carries pollutants into waterways, potentially harming the environment. Obtaining an NPDES permit helps ensure that proper erosion and sediment control measures are implemented, minimizing the impact on water quality. This is a universal requirement, regardless of the area - urban or rural - and is not contingent on the season. Therefore, for any construction activity that meets the land disturbance threshold, securing an NPDES permit is a critical step in complying with environmental regulations.
