Erosion and sediment control
Your county conservation district (for DEP)
Any earth disturbance needs erosion and sediment control practices (BMPs). A written erosion and sediment control plan is required once the disturbance reaches 5,000 square feet (or if the work could discharge to a High Quality or Exceptional Value water), and it must be kept on site. Disturbing 1 acre or more generally needs an NPDES permit for construction stormwater. County conservation districts review these plans and may charge a review fee.
