Waterless toilet systems have been shown to be capable of deactivating and/or killing pathogens through the internal processes. Due to external conditions or operational irregularities, the conditions in the system may not always be optimal for pathogen destruction. Improper handling and disposal of the end product could adversely impact public health by allowing transmission of a variety of enteric disease and parasitic illnesses. The end product of composting must therefore be transported and disposed or reused in a manner that does not create a public health nuisance and is in accordance with the requirements of the Operation and Maintenance Manual and the following requirements:
(a) On-site disposal of the end product from a waterless toilet system shall be prohibited in the following areas:
(1) Shallow subsurface disposal in present or planned food crop growing areas or dairy pasture.
(2) Area subject to seasonal runoff or areas seasonally inundated by water.
(3) Areas within 50 feet of ephemeral streams or 100 feet of perennial streams.
(b) The following methods of end product disposal/reuse are acceptable:
(1) Direct burial on site with a minimum of eighteen (18) inches of compacted soil with a five (5) foot separation to seasonal high ground water.
(2) Disposal into an approved OWTS.
(3) Transportation by a licensed septage hauler to an approved wastewater treatment facility capable of accepting human waste.
(4) End product may be permitted to be used on site around ornamental shrubs, flowers, trees, or fruit trees and shall be mixed with soil or mulch and covered with no less than three inches of cover material. Depositing end product from a waterless toilet system around any edible vegetable or vegetation is prohibited.
(5) End product disposal shall be carried out by methods in subsection (b)(1), (b)(2), or (b)(3) of this section whenever an individual using a waterless toilet has a communicable disease which can be transmitted by human waste contamination of food or water.
(c) All the above reuse methods except subsection (b)(3) of this section shall be limited to the site on which the humus is generated and processed.
