(B) For the purposes of these Rules, a cabin located on a campsite in a
campground is not a building or structure.
(C) For the purposes of these Rules, a remote hut used by outdoor
recreationists with no connection to a water source, no connection to a
wastewater system (other than a composting or incinerating toilet that does
not yield a liquid, provided its contents are disposed of in compliance with
§ 1-929), and accessible only by foot or water, is not a building or
structure.

buildings; condominiums; apartments; mobile homes; hospitals; nursing
homes; motels; hotels; restaurants; filling stations; boarding houses;

(75) Primitive Camp – means a living unit, the occupancy of which neither exceeds 3
consecutive weeks per calendar year nor exceeds a total of 60 days per calendar
year, that has no interior plumbing except for one sink with water. Primitive
camps may contain a composting or incinerating toilet that does not yield a liquid
provided its contents are disposed of in compliance with § 1-929.

§ 1-304 Permit Exemption (3) The construction of a primitive camp, provided:
(A) the primitive camp is on a lot with no other buildings or structures and
with no campground; or
(B) the primitive camp is on a lot with a single-family residence but no other
buildings or structures and no campground.

§ 1-929 Disposal of Contents of Composting or Incinerating Toilets
(a) The contents of a composting or incinerating toilet, provided the toilet does not yield a
liquid, may be disposed of as directed in Subsection (c).
(b) The installation and use of composting or incinerating toilets does not create an
exemption from any requirement of these Rules, including the requirement that all
buildings or structures have wastewater systems that comply with the technical standards
in this Subchapter and Subchapters 8 and 10, for the disposal of all other wastewater from
the building or structure.
(c) The contents removed from a composting or incinerating toilet shall be disposed of in the
following manner:
(1) If disposed of on the same lot on which the toilet is located, the contents shall be
disposed of by shallow burial at a location approved by the Secretary in a permit,
provided the location meets the following requirements:
(A) complies with the isolation distances and isolation zones required pursuant
to § 1-912 for locating an in-ground leachfield; and
(B) maintains a 3-foot separation between the bottom of the excavation for the
contents to the seasonal high-water table and a 4-foot separation between
the bottom of excavation for the contents to bedrock.
(2) If not disposed of on the same lot on which the toilet is located, the contents shall
be disposed of:
(A) at a certified landfill; or
(B) in accordance with the Vermont Solid Waste Management Rules.

§ 1-928 Holding Tanks
(a) The Secretary shall approve the use of holding and pump out tanks as a wastewater
system serving a building or structure in lieu of a soil-based wastewater system or
sanitary sewer service line that conveys wastewater to a wastewater treatment facility or
indirect discharge system when all of the following requirements are met:
(1) The building or structure:
(A) is existing or proposed and is publicly owned; or
(B) is existing and owned by a charitable, religious, or nonprofit organization.
(2) The plan for construction and operation of the holding and pump out tank shall
not result in a public health hazard or environmental damage.
(3) A designer demonstrates that an economically feasible means of meeting current
standards is significantly costlier than wastewater holding and pump out tanks,
based on a projected 20-year life of the project.
(4) The design flows do not exceed 600 gallons per day.
(5) If the building or structure is owned by a charitable, religious, or nonprofit
organization, the applicant agrees to post a bond or other financial surety, prior to
construction of the holding and pump out tank, sufficient to finance maintenance
of the holding and pump out tank for the life of the system which shall be at least
20 years.
