Current through Register Vol. 51, No. 1, July 1, 2024
RELATES TO: KRS 211.350-211.380,
				211.990(2)
NECESSITY, FUNCTION, AND CONFORMITY:
				KRS
				211.350 to
				211.380
				directs the cabinet to regulate the construction, installation, or alteration
				of on-site sewage disposal systems except for systems with a surface discharge.
				The purpose of this administrative regulation is to establish minimum component
				standards including design, construction, and materials specifications for
				on-site sewage disposal systems in Kentucky in order to protect the public
				health.
Section 1. Citation of
			 Administrative Regulation. This administrative regulation may be cited as the
			 "Construction standards for components of on-site sewage disposal
			 systems."
Section 2. Definitions.
			 As used in this administrative regulation the following terms shall have the
			 meanings set forth below:
(1) "Approved" means
			 that which has been considered acceptable to the cabinet.
(2) "Cabinet" means the Cabinet for Human
			 Resources and includes its authorized agents.
(3) "Component" means any device used in the
			 construction, installation or alteration of an on-site sewage disposal system
			 which forms an integral part of that system, and is necessary to its proper
			 operation and maintenance. It includes, but is not limited to:
(a) Sewage pretreatment units, holding tanks,
			 grease traps, pump or dosing tanks, and necessary equipment and
			 appurtenances;
(b) Distribution
			 boxes, alternating valves, filters, and similar devices; and
(c) Piping, fittings, valves, and leaching
			 chambers.
(4) "Effluent"
			 means the liquid discharge of a septic tank or other sewage pretreatment
			 unit.
(5) "Gravelless pipe" means
			 large diameter perforated piping designed for use in lateral field trenches
			 without the use of trench rock or gravel fill material. Such pipe includes a
			 mandatory overwrap or encasing of synthetic filter material meeting specific
			 criteria.
(6) "Grease" means fats
			 or oils of animal, vegetable, or mineral origin, separately or in colloidal or
			 dissolved states in combination with soaps, detergents, and/or food
			 particles.
(7) "Grease trap" means
			 a component designed to separate grease and its constituents from the
			 wastewater stream, provide for storage of separated grease, and discharge the
			 remaining wastewater for treatment.
(8) "Lateral field" means the area in which
			 the subsurface soil absorption system is installed and is a general term for
			 the system itself.
(9) "Low
			 pressure pipe system" means an on-site sewage disposal system consisting of a
			 sewage pretreatment unit, a dosing tank with pump(s) or siphon(s), a
			 pressurized supply line, manifold, and lateral lines, and necessary control
			 devices and appurtenances.
(10)
			 "Leaching chamber" means a specially designed component for use in lateral
			 field trenches or beds, with or without the use of trench rock or gravel fill
			 material, which forms an open bottomed chamber or cavern over the subsurface
			 soil absorption surface, and which interlocks with other such chambers to
			 obtain the necessary absorption surface area.
(11) "On-site sewage disposal system" means a
			 complete system installed on a parcel of land, under the control or ownership
			 of any person, which accepts sewage for treatment and ultimate disposal under
			 the surface of the ground. The common terms "on-site sewage system" or "on-site
			 system" also have the same meaning. This definition includes, but is not
			 limited to, the following:
(a) A conventional
			 system consisting of a sewage pretreatment unit(s), distribution box(es), and
			 lateral piping within rock-filled trenches or beds;
(b) A modified system consisting of a
			 conventional system enhanced by shallower trench or bed placement, artificial
			 drainage systems, dosing, alternating lateral fields, fill soil over the
			 lateral field, or other necessary modifications to the site, system or
			 wasteload to overcome site limitations;
(c) An alternative system consisting of a
			 sewage pretreatment unit(s), necessary site modifications, wasteload
			 modifications, and a subsurface soil absorption system using other methods and
			 technologies than a conventional or modified system to overcome site
			 limitations;
(d) Cluster systems
			 which accept effluent from more than one (1) structure's or facility's sewage
			 pretreatment unit(s) and transport the collected effluent through a sewer
			 system to one (1) or more common subsurface soil absorption system(s) of
			 conventional, modified or alternative design; and
(e) A holding tank which provides limited
			 pretreatment and storage for off-site disposal where site limitations preclude
			 immediate installation of a subsurface soil absorption system, or connection to
			 a municipal sewer.
(12)
			 "Person" means any individual, firm, association, organization, partnership,
			 business trust, corporation, company or governmental unit.
(13) "Secretary" means the Secretary for the
			 Cabinet for Human Resources.
(14)
			 "Sewage pretreatment unit" means a watertight sewage treatment structure
			 designed and constructed to receive raw sewage, separate solids from liquids,
			 digest organic matter through a period of retention, and allow clarified
			 effluent to discharge to a subsurface soil absorption system. Such pretreatment
			 units fall into three (3) basic categories:
(a) Septic tanks - which rely predominantly
			 on anaerobic bacterial action for treatment;
(b) Aerobic units - which introduce
			 atmospheric air into the sewage to promote treatment by aerobic bacteria;
			 and
(c) Combination units - which
			 provide treatment through both anaerobic and aerobic bacterial action and/or
			 mechanical filtering, ozonation or ultraviolet irradiation.
(15) "Subsurface soil absorption
			 system" means that portion of an on-site sewage disposal system which accepts
			 effluent from a sewage pretreatment unit(s) for further treatment by microbial,
			 plant and animal life within the soil, as well as treatment by filtration,
			 chemical decomposition and bonding within the soil itself, and consists of:
(a) Devices, components, and piping to
			 transport effluent under pressure or by gravity flow, and distribute the
			 effluent to the soil absorption surfaces;
(b) Trenches, beds, chambers, mounds,
			 lagoons, artificial marshes, etc., separately or in combination, which form or
			 enclose the soil absorption surfaces;
(c) Rock, gravel, or other fill materials
			 required within the system, including barrier materials, and fill soil within
			 or over the system; and
(d)
			 Artificial drainage systems, and other necessary site or soil
			 modifications.
