(a)

1. (1) A composting toilet is a device specifically designed to retain and process body wastes and, in some cases, household garbage by biological degradation.

2. (2)

   1. (A) The process may be either thermophilic or mesophilic, depending on the design of the toilet.
   2. (B) Thermophilic devices are normally smaller and require some type of energy input to maintain the desired temperature.
   3. (C) Mesophilic devices rely on the heat produced by the biological process to maintain the required temperature.
3. (3) Whether or not a device can accept household garbage is dependent on product design and intended use.

4. (4)

   1. (A) An incinerating toilet is a device designed to reduce body wastes, both urine and feces, to an ash residue.
   2. (B) The type of energy used to incinerate wastes is dependent upon the design of the device used.

(b)

1. (1) Only premanufactured composting or incinerating toilets authorized by the Department of Health shall be utilized in the onsite wastewater system.
2. (2) Under National Sanitation Foundation standard 41, composting and incinerating devices shall be evaluated by an American National Standards Institute-approved laboratory.
