A National Pollutant Discharge Elimination System (NPDES) Storm Water permit is required for projects where how many acres of land will be disturbed?

A National Pollutant Discharge Elimination System (NPDES) Storm Water permit is required for projects that disturb one or more acres of land. The correct answer states that a permit is needed for projects where between 1 to 5 acres will be disturbed. This requirement is set to help manage the potential for stormwater runoff, which can carry pollutants into water bodies, thus helping to protect water quality.

Understanding the threshold of one acre as the minimum for requiring an NPDES permit is crucial for contractors and developers, as it points to the legal requirements they must comply with when planning land disturbance activities. This permitting process ensures that appropriate measures are taken to control erosion and sediment runoff, safeguarding the environment during construction activities. The other ranges presented do not accurately reflect the regulation, as they either fall below or do not fully encompass the correct range for permitting under the NPDES guidelines.
