Current through Vol. 41, No. 20, July 1, 2024
(a)
List of
				  subcategories.
The narrative and numerical criteria in this section are
				  designed to maintain and protect the beneficial use classification of "Fish and
				  Wildlife Propagation". This classification encompasses several subcategories
				  which are capable of sustaining different climax communities of fish and
				  shellfish. These subcategories are Habitat Limited Aquatic Community, Warm
				  Water Aquatic Community, Cool Water Aquatic Community (Excluding Lake Waters),
				  and Trout Fishery (Put and Take).
(b)
Habitat Limited Aquatic Community
				  subcategory.
(1) Habitat limited
				  aquatic community means a subcategory of the beneficial use "Fish and Wildlife
				  Propagation" where the water chemistry and habitat are not adequate to support
				  a "Warm Water Aquatic Community" because:
(A)
				  Naturally occurring water chemistry prevents the attainment of the use;
				  or
(B) Naturally occurring
				  ephemeral, intermittent or low flow conditions or water levels prevent the
				  attainment of the use, unless these conditions may be compensated for by the
				  discharge of a sufficient volume of effluent to enable uses to be met;
				  or
(C) Human caused conditions or
				  sources of pollution prevent the attainment of the use and cannot be remedied
				  or would cause more environmental damage to correct than to leave in place;
				  or
(D) Dams, diversions or other
				  types of hydrologic modifications preclude the attainment of the use, and it is
				  not feasible to restore the waterbody to its original condition or to operate
				  such modification in a way that would result in the attainment of the use;
				  or
(E) Physical conditions related
				  to the natural features of the waterbody, such as the lack of a proper
				  substrate, cover, flow, depth, pools, riffles, and the like, unrelated to water
				  quality, preclude attainment of the "Warm Water Aquatic Community" beneficial
				  use.

Current through Vol. 41, No. 20, July 1, 2024
(a) To be aesthetically enjoyable, the
				  surface waters of the state must be free from floating materials and suspended
				  substances that produce objectionable color and turbidity.
(b) The water must also be free from noxious
				  odors and tastes, from materials that settle to form objectionable deposits,
				  and discharges that produce undesirable effects or are a nuisance to aquatic
				  life.
(c) The following criteria
				  apply to protect this use:
(1)
Color.
Surface waters of the state shall be virtually free from
				  all coloring materials which produce an aesthetically unpleasant
				  appearance.
(2)
Total
				  phosphorus criterion applicable to designated Scenic River reaches of Mountain
				  Fork River; Lee Creek and Little Lee Creek.
The thirty (30) day
				  geometric mean total phosphorus concentration shall not exceed 0.037 mg/L. The
				  criterion stated in this subparagraph applies in addition to, and shall be
				  construed as to be consistent with, any other provision of this Chapter which
				  may be applicable to such waters.
(3)
Total phosphorus criterion
				  applicable to designated Scenic River reaches of Illinois River, Flint Creek,
				  and Barren Fork Creek.
The total phosphorus six month rolling average of
				  0.037 mg/L shall not be exceeded more than once in a one-year period and not
				  more than three times in a five-year period. The criterion stated in this
				  subparagraph applies in addition to, and shall be construed so as to be
				  consistent with, any other provision of this Chapter which may be applicable to
				  such waters.

Current through Vol. 41, No. 20, July 1, 2024
(a)
General.
The surface waters of the state shall be maintained so
				  that toxicity does not inhibit ingestion of fish and shellfish by humans. The
				  numerical criteria and values for substances listed in the column "Fish
				  Consumption" in Table 2 of Appendix G of this Chapter shall apply to surface
				  waters designated as Warm Water Aquatic Community, Cool Water Aquatic
				  Community, or Trout Fishery.
(b)
Water column criteria to protect for the consumption of fish
				  flesh.
The water column numerical criteria (total recoverable)
				  identified in the "Fish Consumption" column in Table 2 of Appendix G protect
				  human health for the consumption of fish, shellfish and aquatic life. Water
				  column numerical criteria to protect human health for human consumption of fish
				  flesh are considered long-term average standards. For purposes of permitting
				  discharges for attainment of these standards, the permitting authority shall
				  use long-term average receiving stream flows and complete mixing of effluent
				  and receiving water to determine appropriate permit limits.
(c)
Fish tissue levels.
Surface
				  waters of the state shall be maintained to prevent bio-concentration of toxic
				  substances in fish, shellfish, or other aquatic organisms to levels that become
				  a risk to human health.

				and protected, unless it is demonstrated to the State that any lowering of
				groundwater quality:
(1) After an analysis of
				alternatives, is necessary to accommodate important economic and social
				development and is in the public interest; and
(2) Protective measures sufficient to protect
				beneficial uses shall be maintained at all times.

Current through Vol. 41, No. 20, July 1, 2024
(a)
Classifications.
Classification of all groundwater shall be designated as follows:
(1)
(Class I):
				RESERVED
(2)
General
				Use Groundwater (Class II):
These are groundwaters which have good
				quality due to natural conditions and generally have a mean concentration of
				total dissolved solids of less than 3,000 milligrams per liter.
(3)
Limited Use Groundwater (Class
				III):
These are groundwaters which have poor quality due to natural
				conditions and generally have a mean concentration of total dissolved solids of
				greater than or equal to 3000 milligrams per liter but less than 5000
				milligrams per liter.
(4)
Highly Mineralized Treatable Groundwater (Class IV):
These are
				groundwaters which have very poor quality due to natural conditions and
				generally have a mean concentration of total dissolved solids of greater than
				or equal to 5000 milligrams per liter but less than 10,000 milligrams per
				liter.
Oklahoma Administrative Code › Title 252 - Department of Environmental Quality › Chapter 730 - Oklahoma's Water Quality Standards › Subchapter 7 - Groundwater Quality Standards › Section 252:730-7-4 - Criteria for groundwater quality protection

Current through Vol. 41, No. 20, July 1, 2024
(a) Groundwaters
				of the state support many different beneficial uses. The criteria below do not
				require improvement over naturally occurring background concentrations. When
				naturally occurring background concentrations exceed the criterion for a given
				parameter, the naturally occurring background concentration may be utilized as
				a criterion, if suitable. If a given parameter has more than one criterion
				associated with it, the most stringent criteria shall apply to ensure
				beneficial use protection.
(b) The
				following criteria apply to all groundwaters for the protection of beneficial
				uses except those groundwaters specifically referenced in OAC
				252:730-7-4(c).
(1) The groundwaters of the state shall be
				maintained to prevent alteration of their chemical properties by harmful
				substances not naturally found in groundwater.
(2) Protective measures adequate to preserve
				and protect background quality of the groundwater and existing and designated
				groundwater basin classifications shall be maintained at all times.
(3) Protective measures shall also be
				sufficient to minimize the impact of pollutants on groundwater
				quality.
(4) The concentration of
				any synthetic substance or any substance not naturally occurring in that
				location shall not exceed the PQL in an unpolluted groundwater sample using
				laboratory technology. If the concentration found in the test sample exceeds
				the PQL, or if other substances in the groundwater are found in concentrations
				greater than those found in background conditions, that groundwater shall be
				deemed to be polluted and corrective action may be required.
Oklahoma Administrative Code › Title 252 - Department of Environmental Quality › Chapter 730 - Oklahoma's Water Quality Standards › Subchapter 7 - Groundwater Quality Standards › Section 252:730-7-5 - Corrective action

Current through Vol. 41, No. 20, July 1, 2024
(a) Groundwater
				that has been polluted as a result of human activities shall be restored to a
				quality that will support the beneficial uses designated in OAC
				252:730-7-3 for that groundwater,
				or as otherwise specified in a site-specific remediation plan approved by an
				agency of competent jurisdiction.
(b) Measures to remedy, control or abate
				groundwater pollution caused by any person shall be the responsibility of each
				state environmental agency within its jurisdictional areas. Such measures shall
				be prescribed in the Water Quality Standards Implementation Plan of each such
				agency. When regulating activities that have the potential to contaminate
				groundwater from the surface, state environmental agencies shall consider the
				vulnerability level of an affected hydrogeologic basin (for example, more
				stringent measures such as siting limitations, lagoon liners, or additional
				monitoring wells may be required to protect groundwater in hydrogeologic basins
				with High or Very High vulnerability levels).
