Idaho Administrative Code › Title IDAPA 58 - Environmental Quality, Department of › Rule 58.01.16 - WASTEWATER RULES › Section 58.01.16.010 - DEFINITIONS

Current through August 31, 2023
For the purpose of the rules contained in IDAPA 58.01.16,
				"Wastewater Rules," the following definitions apply: (3-31-22)
01.
Available
. Based on public
			 wastewater system size, complexity, and variation in raw waste, a licensed
			 wastewater operator must be on site, on call, or able to be contacted as needed
			 to initiate the appropriate action for normal or emergency conditions in a
			 timely manner. (3-31-22)
02.
Adequate Emergency Storage Capacity
. The emergency storage capacity of a
			 lift station wet well is the volume of the wet well measured between the high
			 water alarm and the gravity sewer invert into the wet well. The collection
			 system shall not be used in the calculation for emergency storage. For the
			 purpose of this definition, "adequate" is defined as twice the estimated
			 emergency response time multiplied by the peak hour flow to the wet well. The
			 high water alarm shall be placed at an elevation below the wet well invert
			 sufficient to achieve the defined volumetric emergency storage capacity.
			 (3-31-22)
03.
Average Day
			 Flow
. The average day flow is the average of daily volumes to be
			 received for a continuous twelve (12) month period expressed as a volume per
			 unit time. However, the average day flow for design purposes for facilities
			 having critical seasonal high hydraulic loading periods, such as recreational
			 areas or industrial facilities, shall be based on the average day flow during
			 the seasonal period. See also the definition of Wastewater Flows.
			 (3-31-22)
04.
Beneficial
			 Use
. Any of the various uses which may be made of the water of Idaho,
			 including, but not limited to, domestic water supplies, industrial water
			 supplies, agricultural water supplies, navigation, recreation in and on the
			 water, wildlife habitat, and aesthetics. The beneficial use is dependent upon
			 actual use, the ability of the water to support a non-existing use either now
			 or in the future, and its likelihood of being used in a given manner. The use
			 of water for the purpose of wastewater dilution or as a receiving water for a
			 waste treatment facility effluent is not a beneficial use. (3-31-22)
05.
Biochemical Oxygen Demand
			 (BOD)
. The measure of the amount of oxygen necessary to satisfy the
			 biochemical oxidation requirements of organic materials at the time the sample
			 is collected; unless otherwise specified, this term will mean the five (5) day
			 BOD incubated at twenty (20) degrees C. (3-31-22)
06.
Blackwaste
. Human body
			 waste, such as excreta or urine. This includes toilet paper and other products
			 used in the practice of personal hygiene. (3-31-22)
07.
Blackwater
. A wastewater
			 whose principal pollutant is blackwaste; a combination of blackwaste and water.
			 (3-31-22)
08.
Board
.
			 The Idaho Board of Environmental Quality. (3-31-22)
09.
Capacity
. The capabilities
			 required of a wastewater system in order to achieve and maintain compliance
			 with these rules. It is divided into three (3) main elements: (3-31-22)
a. Technical capacity means the system has
			 the physical infrastructure to safely collect wastewater and consistently meet
			 discharge 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. (3-31-22)
b. Financial capacity means the financial
			 resources of the wastewater system, including an appropriate budget; rate
			 structure; cash reserves sufficient for current operation and maintenance,
			 future needs and emergency situations; and adequate fiscal controls.
			 (3-31-22)
c. Managerial capacity
			 means that the management structure of the wastewater system embodies the
			 aspects of wastewater system operations, including, but not limited to;
			 (3-31-22)
i. Short and long range planning;
			 (3-31-22)
ii. Personnel management;
			 (3-31-22)
iii. Fiduciary
			 responsibility; (3-31-22)
iv.
			 Emergency response; (3-31-22)
v.
			 Customer responsiveness; and (3-31-22)
vi. Administrative functions such as billing
			 and consumer awareness. (3-31-22)
