Are erosion controls required after construction is complete?

Controls must remain in place until permanent stabilization is achieved, typically 70 percent vegetative cover. After that, post-construction stormwater controls take over.

Can my contractor ignore controls during dry weather?

No. State rules require functional sediment controls regardless of current weather, since storm events can occur without warning. Inspections continue weekly.

Who can be penalized for sediment violations?

The permittee, owner, and operator can each be liable. DHEC may pursue any responsible party for civil penalties and corrective action.

Full Breakdown

Under SC Code Title 48, Chapter 14 and Regulation 72-300, all land disturbance of one acre or greater requires implementation of erosion and sediment control best management practices including silt fences, sediment basins, stabilized construction entrances, and prompt seeding or stabilization. The SC DHEC Stormwater BMP Manual specifies technical design criteria that must be met. Sites must maintain controls until permanent stabilization of 70 percent vegetative cover. Inspections are required at minimum every seven days and after rain events of 0.5 inches or more.

Violations & Penalties

Failure to implement controls is enforceable by DHEC with civil penalties up to $1,000 per day per violation. Stop-work orders and mandatory restoration may be ordered. Repeat violators face escalated enforcement.
