Inspection and enforcement can be divided into two distinct categories, during construction and post construction. Construction inspection ensures that the storm drainage systems, stormwater management facilities and erosion and sediment control measures are constructed and installed in accordance with the approved C-SWPPP and OS-SWPPP. All construction inspection shall conform as outlined in the most current SCDHEC NPDES General Permit for Stormwater Discharges for Construction Activities. In addition, the following apply:
(a) No stage of work, related to the construction of stormwater management facilities, shall proceed the next preceding stage of work, according to the sequence specified in the approved staged construction and inspection control schedule until it is inspected and approved.
(b) The permittee shall notify the Land Development Division before commencing any work to implement the OS-SWPPP and upon completion of the work.
(c) Third party inspections, by a qualified individual who is independent of the owner must comply as outlined in the most current SCDHEC’s NPDES General Permit for Stormwater Discharges from Construction Activities or may be required at the discretion of the Director at sites that have compliance problems and at sites where stormwater discharges to environmental sensitive waters (such as waters classified as Trout Waters, Outstanding Resource Waters, Shellfish Harvesting Waters, etc.).
(d) Once construction is complete, a final inspection will be conducted, and as-built documentation will be submitted to show that the constructed project meets the requirements of the approved C-SWPPP and OS-SWPPP. At this point the land disturbance permit is closed and the responsibility for the operation and maintenance of the storm drainage systems and stormwater management facilities is transferred from the operator to the persons responsible for maintenance.
(e) The operator shall provide an “as-built” plan certified by a registered professional to be submitted upon completing of the stormwater management facilities included in the C-SWPPP. The registered professional shall certify that:
(1) The facilities have been constructed as shown on the “as-built” plan; and
(2) The facilities meet the approved C-SWPPP or achieve the function for which they were designed.
(f) Acceptable “as-built” plans shall be submitted prior to:
(1) The use or occupancy of any commercial or industrial site.
(2) Final acceptance of any road into the Official County Road Inventory.
(3) Release of any performance security held by the County.
(4) Approval of a new C-SWPPP if the plan proposes to use an existing stormwater management facilities that does not have an acceptable “as-built” plan on file at the Land Development Division’s office.
(5) Approval and/or acceptance for recording of map plat or drawing, the intent of which is to cause a division of a single parcel of land into 2 or more parcels.
(g) The Director shall report the performance of any non-performing Certified Erosion and Sediment Control Inspector to the South Carolina Department of Health and Environmental Control and to Clemson University for appropriate action.
(h) After construction is complete the persons responsible for maintenance are required to conduct periodic inspections of the stormwater management facilities, features or BMPs. Inspections must be documented and maintenance for future verification. The County will conduct periodic post-construction compliance inspections. During the compliance inspections the persons responsible for maintenance may be required to provide copies of their inspection and maintenance activities documentation to the County.
