A valid SCDHEC septic system permit must be submitted to the city for new construction, substantial improvement, change in occupancy, or renovation that increases the number of bedrooms. The number of bedrooms allowed shall be determined as defined by this chapter so the system will not be undersized.
(A) Permit required.
(1) The number of bedrooms must correspond to the number of gallons per day of approved flow indicated on the SCDHEC permit application at a rate of 120 gallons per day, per bedroom.
(2) A permit to construct the system must be issued by SCDHEC before construction on the structure or the septic system can begin.
(3) The proposed system must be located adjacent to the most landward SCDHEC septic setback and as landward as possible unless the property owner can demonstrate that the area is unsuitable. In no instance shall a building permit be issued for a structure for which the proposed septic system is located within the dune management area.
(B) Certificate of final approval. The owner must receive a SCDHEC certificate of final approval to operate the system before the city can issue a certificate of occupancy (CO.).
(C) Survey required. Any application for a change of occupancy, new construction, substantial improvement, or renovation which relies on a SCDHEC approved septic permit dated prior to January 1, 2007 shall require a survey which:
(1) Is stamped by a licensed SC surveyor or engineer;
(2) Shows the location of all components of the proposed septic system;
(3) Indicates the nearest distance from any portion of the septic system to the baseline or a critical line. Any baseline or critical line indicated on the survey must be certified by SCDHEC OCRM;
(4) Clearly displays the setbacks required by SCDHEC at date of original approval of the septic permit; and
(5) Shows all proposed parking areas.
