Idaho Administrative Code › Title IDAPA 58 - Environmental Quality, Department of › Rule 58.01.08 - IDAHO RULES FOR PUBLIC DRINKING WATER SYSTEMS › Section 58.01.08.003 - DEFINITIONS

Current through August 31, 2023
The definitions set forth in
				40 CFR
				141.2 are herein incorporated by reference
				except for the definition of the terms "action level," "disinfection,"
				"noncommunity water system," and "person." (3-24-22)
01.
Action Level
. The
			 concentration of lead or copper in water that determines, in some cases,
			 whether a water system must install corrosion control treatment, monitor source
			 water, replace lead service lines, or undertake a public education program.
			 (3-24-22)
02.
Administrator
. The Administrator of the United States
			 Environmental Protection Agency. (3-24-22)
03.
Annual Samples
. Samples that
			 are required once per calendar year. (3-24-22)
04.
Annular Opening
. As used in
			 well construction, this term refers to the nominal inside diameter of the
			 borehole minus the outside diameter of the casing divided by two (2).
			 (3-24-22)
05.
Aquifer
.
			 A geological formation of permeable saturated material, such as rock, sand,
			 gravel, etc., capable of yielding an economic quantity of water to wells and
			 springs. (3-24-22)
06.
Average Day Demand
. The volume of water used by a system on an
			 average day based on a one (1) year period. See also the definition of Water
			 Demand in these rules. (3-24-22)
07.
Backflow
. The reverse from
			 normal flow direction in a plumbing system or water system caused by back
			 pressure or back siphonage. (3-24-22)
08.
Bag Filters
. Pressure-driven
			 separation devices that remove particulate matter larger than one (1)
			 micrometer using an engineered porous filtration media. They are typically
			 constructed of a non-rigid, fabric filtration media housed in a pressure vessel
			 in which the direction of flow is from the inside of the bag to the outside.
			 (3-24-22)
09.
Bank
			 Filtration
. A water treatment process that uses a well to recover
			 surface water that has naturally infiltrated into ground water through a river
			 bed or bank(s). Infiltration is typically enhanced by the hydraulic gradient
			 imposed by a nearby pumping water supply or other well(s). (3-24-22)
10.
Board
. The Idaho Board of
			 Environmental Quality. (3-24-22)
11.
Capacity
. The capabilities
			 required of a public drinking water system in order to achieve and maintain
			 compliance with these rules and the requirements of the federal Safe Drinking
			 Water Act. It is divided into three (3) main elements: (3-24-22)
a. Technical capacity means the system has
			 the physical infrastructure to consistently meet drinking water quality
			 standards and treatment requirements and is able to meet the requirements of
			 routine and emergency operations. It further means the ability of system
			 personnel to adequately operate and maintain the system and to otherwise
			 implement technical knowledge. Training of operator(s) is required, as
			 appropriate, for the system size and complexity. (3-24-22)
b. Financial capacity means the financial
			 resources of the water system, including an appropriate budget; rate structure;
			 cash reserves sufficient for current operation and maintenance, future needs
			 and emergency situations; and adequate fiscal controls. (3-24-22)
c. Managerial capacity means that the
			 management structure of the water system embodies the aspects of water system
			 operations, including, but not limited to; (3-24-22)
i. Short and long range planning;
			 (3-24-22)
ii. Personnel management;
			 (3-24-22)
iii. Fiduciary
			 responsibility; (3-24-22)
iv.
			 Emergency response; (3-24-22)
v.
			 Customer responsiveness; (3-24-22)
vi. Source water protection;
			 (3-24-22)
vii. Administrative
			 functions such as billing and consumer awareness; and (3-24-22)
viii. Ability to meet the intent of the
			 federal Safe Drinking Water Act. (3-24-22)
