A. A 4.03
				  General Permit allows for the use of a composting toilet with less than 3000
				  gallons per day design flow
1. Definition.
				  For purposes of this Section, "composting toilet" means a manufactured turnkey
				  or kit form treatment technology that receives human waste from a waterless
				  toilet directly into an aerobic composting chamber where dehydration and
				  biological activity reduce the waste volume and the content of nutrients and
				  harmful microorganisms to an appropriate level for later disposal at the site
				  or by other means.
2. An applicant
				  may use a composting toilet if:
a. Limited
				  water availability prevents use of other types of on-site wastewater treatment
				  facilities,
b. Environmental
				  constraints prevent the discharge of wastewater or nutrients to a sensitive
				  area,
c. Inadequate space prevents
				  use of other systems,
d. Severe
				  site limitations exist that make other forms of treatment or disposal
				  unacceptable, or
e. The applicant
				  desires maximum water conservation.
3. A permittee may use a composting toilet
				  only if:
a. Wastewater is managed as provided
				  in this Section and, if gray water is separated and reused, the gray water
				  reuse complies with18 A.A.C. 9, Article 7; and
b. Soil conditions support subsurface
				  disposal of all wastewater sources.

1. Definition. For purposes of this Section,
				  a "pressure distribution system" means a tank, pump, controls, and piping that
				  conducts wastewater under pressure in controlled amounts and intervals to a bed
				  or trench or other means of distribution authorized by a general permit for an
				  on-site wastewater treatment facility.
2. An applicant may use a pressure

				  Definition. For purposes of this Section, a "gravelless trench" means a
				  disposal technology characterized by installation of a proprietary pipe and
				  geocomposite or other substitute media into native soil instead of the
				  distribution pipe and aggregate fill used in a trench allowed in
				  R18-9-E302.
2. A permittee may use
				  a gravelless trench if suitable gravel or volcanic rock aggregate is
				  unavailable, excessively expensive, or if adverse site conditions make movement
