South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-56 - ONSITE WASTEWATER SYSTEMS › Section 61-56.400 - Appendices of Standards for Permitted Systems › Appendix 61-56.400.S - Nonwater-Carried Sewage Treatment Systems

Current through Register Vol. 48, No. 6, June 28, 2024
(1) The permitting of nonwater-carried sewage treatment
				  systems, such as a biological, composting, or incinerating toilet, may be
				  considered for toilet wastes when a proposed site is unsuitable for the
				  issuance of an onsite wastewater system permit under the system standards in
				  Appendices A through R. Nonwater-carried sewage treatment systems 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 nonwater-carried sewage treatment 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
				  nonwater-carried sewage treatment system and demonstrate the following:
(a) The system complies with all local codes and
				  ordinances.
(b) All products and processes meet applicable National
				  Sanitation Foundation (NSF) Standards and American National Standards Institute
				  (ANSI) Standard 41 and bear the seal of approval of the NSF or an equivalent
				  testing and certification program.
(c) Compartment and appurtenances are insect and vector-proof
				  and have continuous exterior ventilation.
(d) There will be no liquid wastewater produced by the
				  system.
(e) 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.
(f) All manufacturer recommendations for installation,
				  operation, and maintenance will be followed.
(3) Applicants seeking to install a nonwater-carried sewage
				  treatment system at a site where water under pressure will be connected to the
				  structure and gray water is generated (from showers, sinks, etc.), but where
				  nonwater-carried sewage treatment systems will be the only means for toilet
				  waste disposal, must:
(a) Submit plans from a Registered Professional Engineer
				  licensed in South Carolina that meet the requirements of Appendix S, paragraphs
				  (2)(a) through (f), 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 nonwater-carried sewage treatment 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.
