Current through Register Vol. 13, July 5, 2024
(1)
				The provisions of (2) through (5) apply only to existing non-public sewage
				systems in proposed subdivisions. Facilities previously approved under Title

				and rules promulgated thereunder.
(2) If an existing sewage treatment system is
				present, the department shall review the adequacy of the existing system for
				the proposed use and the capability of the existing system to operate without
				risk to public health and without pollution of state waters. To assist the
				department in making this determination, the applicant shall submit the
				following information, together with fees as provided in ARM 17.36.802:
(a) evidence demonstrating the proper
				hydraulic functioning of each existing system;
(b) evidence as to whether each existing

(c) a parcel that will be affected
				by a proposed boundary line adjustment, if the parcel has existing facilities
				for water supply, wastewater disposal, storm drainage, or solid waste disposal
				that were not subject to review, and have not been reviewed, under Title 76,
				chapter 4, part 1, MCA, and if:
(i) no
				facilities, other than those in existence prior to the boundary line
				adjustment, or those that were previously approved as replacements for the
				existing facilities, will be constructed on the parcel;
(ii) existing facilities on the parcel
				complied with state and local laws and regulations, including permit
				requirements, which were applicable at the time of installation; and

Current through Register Vol. 13, July 5, 2024
(1) Except as
				provided in (2) and (3), treatment and disposal of gray water must be by means
				of a wastewater treatment system that meets all of the requirements of this
				subchapter and applicable department circulars. Gray water reuse within a
				building or residence for uses such as toilet flushing is permitted without a
				permit under this subchapter, provided that the gray water is ultimately
				disposed of by means of a wastewater treatment system that is in compliance
				with this subchapter and applicable department circulars.
(2) Gray water may be used for irrigation as
				provided in (3). If a gray water irrigation system meets all of the
				requirements in (3), the system is not subject to the requirements of ARM
				17.36.914,
				17.36.916, and
				17.36.918.
(3) Gray water that is collected separately
				from sewage flow and that does not contain industrial chemicals, hazardous
				wastes, or wastewater from toilets may be used for irrigation, if the following
				requirements are met:
(a) prior to
				installation, a gray water irrigation system must obtain a permit under this
				subchapter;
(b) gray water
				irrigation must be subsurface, using a collection and application system that
				is designed, installed, and used in accordance with Department Circular
				DEQ-4;
(c) as provided in
				75-5-326, MCA, gray water may not
				be used to irrigate plants to be consumed by humans, and gray water systems may
				not be located in a floodplain, as defined in
				76-5-103, MCA. For purposes of
				this rule, "plants to be consumed by humans" does not include nut and fruit
				trees;
(d) there must be a minimum
				vertical separation of four feet of natural soil between the point of gray
				water application and a limiting layer, as defined in ARM
				17.36.912;
(e) gray water irrigation may not occur
				within:
(i) 100 feet of wells;
(ii) 100 feet of surface water;
(iii) 100 feet of a flood plain; or
(iv) two feet of a property line;
(f) gray water from kitchens may
				be used for irrigation only where a waste segregation system is used. For
				purposes of this rule, a "waste segregation system" consists of dry disposal of
				toilet waste by a method such as composting, chemical, dehydrating, or
				incinerator treatment, with a separate disposal method for gray
				water;
(g) if required under Title

Current through Register Vol. 13, July 5, 2024
(1) For the
				purposes of this rule, "significant deficiency" means any defect in design,
				operation, or maintenance of a public water supply system or public sewage
				system, or a failure or malfunction of the system, that the department
				determines causes, or has the potential to cause, the introduction of fecal,
				chemical, or other contamination into a drinking water supply or a source of
				ice. The term also includes practices and conditions that hinder the
				determination of the source or potential source of contamination, such as
				improper sample locations or sample taps.
(2) If the department determines that a
				significant deficiency exists with a public water supply system or a public
				sewage system, the department shall provide written notice to the system owner.
				The system owner shall correct the deficiency in accordance with a plan and
				timeframe approved by the department.
(3) If the department has reason to believe
				that a significant deficiency or sanitary defect may exist with a public water
				supply system or a public sewage system, the department may request the system
				owner to provide additional information to assist the department in making a
				final determination. The system owner shall provide the department with the
				requested information. If the system owner fails to supply the requested
				information, the department may make a determination based on available
				information about the potential risk of contamination from the system to
				drinking water or a source of ice, and the department may require the system
				owner to take measures that the department determines are appropriate to
				prevent contamination.
