Oklahoma Administrative Code › Title 252 - Department of Environmental Quality › Chapter 616 - Industrial Wastewater Systems › Subchapter 1 - Introduction › Section 252:616-1-2 - Definitions

Current through Vol. 41, No. 20, July 1, 2024
The following words and terms, when used in this Chapter,
				  shall have the following meaning, unless the context clearly indicates
				  otherwise:
"Beneficial use"
means in the context of land
				  application the use of sludge or wastewater through land application for the
				  purpose of soil conditioning, crop vegetative fertilization, or erosion
				  control, or the use of wastewater for dust suppression where fugitive dust
				  control would otherwise be an air quality problem, in a manner which does not
				  pollute or tend to pollute waters of the state of Oklahoma, the environment or
				  pose a risk to human health.
"Berm"
means a man-made barrier designed to
				  control waste and/or stormwater within a surface impoundment or to retard or
				  contain runoff in a given area.
"Bypass"
means the intentional or unintentional
				  diversion of waste streams from any portion of a facility.
"Cathodic protection"
means protecting a metal
				  from electrochemical corrosion or rusting by using it as the cathode of a cell
				  with a sacrificial anode.
"Cell"
means a part of a surface impoundment
				  system that shares a vertical concrete wall with another part of the surface
				  impoundment area.
"DEQ"
means the Oklahoma Department of
				  Environmental Quality.
"Engineer"
means a professional engineer
				  registered in the state of Oklahoma.
"Flow-through surface impoundment"
means a
				  surface impoundment designed and constructed with an outfall structure which
				  allows the controlled discharge of wastewater out of the impoundment.
"Freeboard"
means the vertical distance from the
				  surface water or sludge/solids level to the overflow elevation (outfall
				  structure or the lowest part of the surrounding berm) in a surface impoundment.
"Hydraulic conductivity"
means the coefficient
				  of proportionality that describes the rate at which a fluid can move through a
				  permeable medium. It is a function of both the medium and of the fluid flowing
				  through it; also defined as the quantity of water that will flow through a unit
				  cross-sectional area of porous material per unit of time under a hydraulic
				  gradient of 1.00 (measured at right angles to the direction of flow) at a
				  specified temperature.
"Industrial wastewater treatment permit"
shall
				  include any permit for construction, operation, treatment, storage or disposal
				  required under this Chapter.
"Land application"
means the controlled
				  application of treated industrial wastewater or sludge onto the land surface
				  for beneficial use.
"Liner"
means a barrier which is designed,
				  constructed and installed in a surface impoundment and which has appropriate
				  chemical and physical properties to ensure that such structures control the
				  seepage or release of waste and wastewater from the impoundment.
"Monitoring well"
means all borings, wells,
				  piezometers, or other means of retrieving a soil, waste, wastewater or vapor
				  sample from the subsurface.
"Oklahoma Water Quality Standards"
means the
				  rules promulgated by the DEQ and contained in OAC 252:730 which classify waters
				  of the state, designate beneficial uses for which the various waters of the
				  State shall be maintained and protected, and prescribe the water quality
				  standards required to sustain designated uses.
"OPDES"
means the Oklahoma Pollution Discharge
				  Elimination System Act at 27A O.S. § 2-6-201
et
				  seq
.
"Operator"
means the person responsible for the
				  maintenance and operation of a surface impoundment, or disposal or wastewater
				  treatment system and responsible for keeping records and providing reports to
				  the DEQ.
"Outfall"
means the point where monitoring shall
				  occur for the purpose of evaluating compliance with rules, permits or orders of
				  the DEQ.
"Person"
means any individual, company,
				  corporation, government agency, municipality, or any other entity.
"Permeability"
means the rate at which liquids
				  pass through soil or other materials in a specified direction.
"Receiving water"
means that portion of any
				  waters of the State into which wastewater is or may be released, leached, or
				  discharged.
"Sanitary wastewater"
means and includes but is
				  not limited to wastewater from drinking fountains, showers, toilets,
				  lavatories, and kitchens.
"Surface impoundment"
means a native soil or
				  lined basin either below or above ground level which is designed, maintained
				  and/or operated to store, recycle, treat and/or dispose of industrial
				  wastewater or stormwater, and shall include but is not limited to lagoons,
				  excavations, basins, diked areas, and pits.
"Synthetic liner"
means a manufactured liner
				  material composed of plastics, resins or other flexible materials, which is
				  designed and manufactured to be used to control the seepage or release of waste
				  through the liner material.
"Tank system"
means any subsurface disposal
				  system which involves the storage and treatment of wastewater.
"Total retention surface impoundment"
means a
				  surface impoundment designed and constructed without an outfall
				  structure.
" U.S.C."
means United States Code.
"Waste class"
means the following classification
				  of wastewater, including stormwater:
(A) Class I: containing or suspected to
				contain pollutants for which the toxicity, concentration and volume pose a
				significant risk of harm to humans, aquatic life, wildlife or the environment,
				either through high potential to migrate in groundwater or the likelihood, if
				discharged, to significantly degrade the beneficial uses of the receiving water
				as designated in the Oklahoma Water Quality Standards. These wastewaters
				require the most restrictive environmental protection measures.
(B) Class II: containing or suspected to
				contain pollutants for which the toxicity, concentration and volume pose a
				moderate risk of harm to humans, aquatic life, wildlife, or the environment,
				either through the potential to migrate in groundwater or a reasonable
				possibility, if discharged, to degrade the beneficial uses of the receiving
				water as designated in the Oklahoma Water Quality Standards.
(C) Class III: containing or suspected to
				contain pollutants which do not pose a substantial risk of harm to humans,
				aquatic life, wildlife, or the environment because of a relative immobility in
				groundwater or a general lack of direct toxicity, and which are not likely, if
				discharged, to degrade the beneficial uses of the receiving water as designated
				in the Oklahoma Water Quality Standards.
(D) Class IV: containing only sanitary
				wastewater from industrial facilities. Class IV wastewaters are not subject to
				this Chapter, but are governed by OAC 252:641 (under 5,000 gpd) or by OAC
				252:656 (5,000 gpd or more).
(E)
				Class V: industrial wastewater not otherwise classified.
"Waste containment system"
means storage tanks,
				  containers and other storage reservoirs, transfer lines, pumps, fittings,
				  overfill prevention devices, and any associated anticorrosion measures and leak
				  prevention or detection systems.
