BMP inspections for South Carolina construction sites

Any construction activity disturbing one acre or more in South Carolina requires coverage under the SCDHEC Construction General Permit and NPDES permit authorization. The permit sets a fixed inspection schedule: at minimum every seven calendar days during active land disturbance, and within 24 hours of a rainfall event measuring 0.5 inches or greater. Both clocks run independently. A rain event inspection does not reset the weekly schedule.

Drone coverage reaches the full site in a single flight. Silt fence along the perimeter, sediment basins and traps, inlet protection at each drop and curb inlet, stabilized construction entrances, slope stabilization, and any areas of active erosion. One flight captures every BMP location at a consistent point in time, with dated aerial imagery at each one.

Deliverables are organized for direct insertion into a SWPPP inspection log without additional sorting.

Weekly and bi-weekly plans are available for active sites. Rain event inspections are available same-day across most of South Carolina. Call or text before 7 AM for same-day rain event coverage. Deliverables within 48 hours of the flight on standard plans.

For environmental consultants managing multiple permitted sites: we work as a drone documentation subcontractor. You remain the qualified inspector of record and sign the inspection record. We provide the aerial documentation. See SWPPP inspection support for details on multi-site scheduling.

Inspections are required from initial land disturbance through final stabilization, defined under the SCDHEC Construction General Permit as 70% permanent vegetative cover on all disturbed areas or pavement and concrete over all disturbed ground. SCDHEC conducts site inspections and checks that the inspection record is current and complete. A site with failed BMPs and a complete record is in a better position than a site with intact BMPs and a missing one.
