S.C. Code Regs. § ch. 61, 61-56, 61-56.400, app 61-56.400.T
(1) Wastewater combustion systems may be considered when a proposed site is unsuitable for the issuance of an onsite wastewater system permit under the system standards in Appendices A through R. A wastewater combustion system shall be designed, installed, maintained, and operated without endangering public health, the environment, or creating a nuisance.
(2) With the application for a permit to construct, all applicants seeking to install a wastewater combustion system must submit to the Department plans from a Registered Professional Engineer licensed in South Carolina that describe the design and installation of the proposed wastewater combustion system and demonstrate the following:
(a) The system complies with all local codes and ordinances.
(b) CSA Group certification of the wastewater combustion system in the United States.
(c) The system must be of adequate size to handle the wastewater volume and peak flow generated by the structure.
(d) Compartment and appurtenances are insect and vector-proof and have continuous exterior ventilation.
(e) All liquid wastewater produced must be sent to the combustion system. Liquid wastewater must not be sent to an onsite wastewater system or held in a storage system to be pumped and hauled.
(f) Methods for training the owner/operator in the proper use, function, and maintenance of the system including safe handling and disposal methods for any residue generated by the system.
(g) All manufacturer recommendations for installation, operation, and maintenance will be followed.
(3) Applicants seeking to install a wastewater combustion system for toilet wastes in conjunction with an onsite wastewater system for treatment of gray water generated by the structure must:
(a) Submit to the Department plans from a Registered Professional Engineer licensed in South Carolina that meet the requirements of Appendix T, paragraphs (2)(a) through (g), for all toilet wastes; and
(b) Apply for and obtain a Department permit to construct and approval to operate an onsite wastewater system for treatment of gray water. This system must meet all permit, licensing, and onsite wastewater system requirements under this regulation, except that the initial system size may be reduced by twenty-five (25) percent.
(4) A licensed installer is not required for the installation of a wastewater combustion system under this standard. However, engineering certifications using the applicable Department form must be submitted to the Department before the Department will issue an approval to operate a system under this standard.
