§ 44-55-822 — Preliminary tract evaluation; issuance of preliminary and final subdivision approval letters; determination of suitability for use of onsite wastewater systems.

(A)(1) The Department of Health and Environmental Control may issue a preliminary tract evaluation for tracts of land that may be developed in the future. For purposes of this section, a tract of land is any tract of land that is not yet divided into individual lots for the immediate or future purpose of building development. A preliminary tract evaluation will determine whether a tract of land is conceptually appropriate for the use of onsite wastewater systems. If the proposed subdivision is found to be suitable for onsite waste treatment systems, the department shall issue a preliminary subdivision approval letter. (2) When conducting a preliminary tract evaluation, the department shall consider a variety of factors including, but not limited to, soil maps, boundary plat, and distance to the nearest sewer line. The department may determine what documents and other supporting materials must be submitted with an application for a preliminary tract evaluation. When making a determination on a preliminary tract evaluation, the department may receive and consider information and data on soil from registered soil classifiers and other site conditions from engineers. (B)(1) The Department of Health and Environmental Control may issue a preliminary subdivision approval letter for subdivisions where the use of onsite wastewater systems is proposed as the method of sewage treatment and disposal. For purposes of this section, a subdivision is any tract of land divided into five or more lots for the immediate or future purpose of building development where onsite wastewater systems are to be considered except where all of the lots are five acres or larger, regardless of the number of lots. (2) The department must not issue a final subdivision approval letter for a residential subdivision for which it has approval responsibility without first conducting a soil suitability test on each lot in the proposed subdivision. The suitability test must determine if the soil conditions on each lot meet the requirements of regulation to support the use of an onsite wastewater system. The department shall issue permits on each approved lot within the subdivision if all of the conditions for permitting have been met pursuant to regulation. Following the completion of the soil suitability test for each lot as submitted by the developer, the department shall issue a final subdivision approval letter indicating the approval or disapproval for each lot in the proposed subdivision. (3) The department shall provide space on its "Application for Subdivision of Real Estate", or another applicable form in use, for the developer of the proposed subdivision to indicate the typical setback on the lots and the typical size house that is anticipated to be built in the proposed subdivision. Changes in the house size, addition of landscaping features, addition of structures, addition of impervious materials or other site alterations could jeopardize permitting a septic tank system for a proposed lot. If the septic permit application is denied for any reason, the department shall inform the subdivision lot owner if any corrective measures could be taken to remedy the problem and lead to the issuance of a septic tank permit.
