103.1. General.
(1) Each dwelling, business, or other
			 structure occupied for more than two (2) hours per day shall be provided with
			 an approved method for the treatment and disposal of domestic
			 wastewater.
(2) It shall be the
			 responsibility of the property owner to ensure that a permit to construct and
			 operate any new, upgraded, or expanded onsite wastewater system,
			 nonwater-carried sewage treatment system, wastewater combustion system, or gray
			 water subsurface reuse system is obtained from the Department prior to
			 construction and operation of the system.
(3) No person shall begin construction of a
			 dwelling, business, or other structure to be served by an onsite wastewater
			 system, nonwater-carried sewage treatment system, wastewater combustion system,
			 or gray water subsurface reuse system until a permit to construct and operate
			 such a system is issued by the Department.
Mobile or modular structures intended for occupancy shall not
				be moved onto the site until the permit to construct and operate an onsite
				wastewater system has been issued.
(4) The property owner shall be required to
			 properly operate and maintain in good working order all onsite wastewater
			 system(s) and their parts and to comply with all terms and conditions of a
			 previously issued permit. System parts may include, but are not limited to,
			 sealed watertight tanks, lid(s), piping, aggregate, pump, and pump
			 components.
(5) An onsite
			 wastewater system serving more than one (1) piece of deeded property shall be
			 considered as a community or cluster collection and treatment system and shall
			 comply with the following:
(a) A permit
			 activity will not occur that is inconsistent with a plan or plan amendment
			 approved under section 208(b) of the Clean Water Act unless the Department
			 finds such variance necessary to protect the public's health, safety, and
			 welfare.
(b) If a public entity
			 owns the system, the entity shall be responsible for the operation,
			 maintenance, and replacement of all components unless otherwise approved by the
			 Department. The Department may consider a request from a private entity or
			 person; however, such proposals must be evaluated on a case-by-case basis. The
			 Department will evaluate the capability of long-term, reliable system operation
			 in its evaluation of a permit request.
(c) If the project is owned by a private
			 entity or person, the Department shall require financial assurances for the

			 primary subsurface wastewater infiltration area.

			 of a community onsite wastewater system shall receive a separate Construction
			 Permit under R.61-67.300, Standards for Wastewater Facility
