Current through Vol. 41, No. 20, July 1, 2024
(a)
General.
The rules in this Subchapter provide protocols
										which shall be used on and after October 1, 2000 to determine whether certain beneficial uses of waters of
										the state designated in OAC 785:45 are being supported. Such determinations shall be made only to the extent
										that pertinent provisions of OAC 785:45 apply to a waterbody or its designated uses. The rules in this
										Subchapter are not intended and should not be construed to limit any actions by federal or state agencies or
										citizens to prevent pollution or to limit remedies to abate pollution from a single incident or activity or
										series of incidents or activities.
(b)
Significance of
										assessment that a use is other than fully supported.
A determination based upon application of the
										rules in this Subchapter that a waterbody's beneficial use is not supported or is partially supported creates
										a presumption that the use is impaired or not attained for that waterbody and that the waterbody segment is a
										water quality limited segment.
(c)
Agency discretion to
										consider additional data.
An agency with jurisdiction may consider other relevant data meeting the
										requirements of this Subchapter in addition to that required by the rules in this Subchapter for any
										particular parameter to determine full support or non-support.

"Screening level"
means an evaluation threshold based upon
											  criteria prescribed in OAC 785:45 to protect a designated beneficial use.

Oklahoma Administrative Code › Title 785 - Oklahoma Water Resources Board › Chapter 46 - Implementation of Oklahoma's Water Quality Standards › Subchapter 15 - Use Support Assessment Protocols › Section 785:46-15-3 - Data requirements

Current through Vol. 41, No. 20, July 1, 2024
(a)
General.
In order to determine whether a given beneficial
										use of a waterbody is supported, scientific data from the waterbody shall be used as prescribed in this
										Section. Data shall be collected and analyzed in a manner consistent with testing procedures provided in
										785:45-1-4 or practices that are institutionally recognized and
										appropriate for the parameter of concern and documented in accordance with 785:46-15-3(g). All existing data
										available for a waterbody shall be used in the analysis, subject to the spatial, temporal and other
										requirements of this Section.
(b)
Spatial coverage.
(1)
General for streams.
The spatial extent of assessment of
										use support in terms of stream miles shall be determined after taking into account existing data, spatial
										distribution of monitoring sites, sources of pollution and influence of tributaries. Major hydrological
										features, such as the confluence of a major tributary or a dam, may limit the spatial extent of an assessment
										based on one station.
(2)
Non-wadable streams.
Unless it is demonstrated to the contrary, a single monitoring site shall be considered representative of no
										more than 25 stream miles for non-wadable streams.
(3)
Wadable streams.
Unless it is demonstrated to the contrary, a single monitoring site shall be
										considered representative of no more than 10 stream miles for wadable streams.
(4)
Lakes.
The spatial extent of assessment of use support in
										terms of lake surface acres shall be estimated based on the spatial distribution of monitoring sites having
										the requisite number of samples, sources of pollution, influence of tributaries and best professional
										judgment. Arms or portions of lake may be treated separately from the main body of a lake. Unless it is
										demonstrated to the contrary, a single site shall be considered representative of an entire lake or an arm of
										no more than two hundred and fifty surface acres in size.
(5)
Spatial limitation for sampling sites.
For purposes of this Subchapter, observations, samples,
										and other data shall not be taken within any regulatory mixing zone.

Current through Vol. 41, No. 20, July 1, 2024
(a)
General.
The protocols prescribed in this Section shall
										apply whenever the more specific protocols prescribed elsewhere in this Subchapter do not apply.
(b)
Short term average numerical parameters.
(1) Short term average numerical parameters are based upon exposure periods
										of less than seven days. Short term average parameters to which this Section applies include, but are not
										limited to, sample standards and turbidity.
(2) A beneficial use
										shall be deemed to be fully supported for a given parameter whose criterion is based upon a short term
										average if 10% or less of the samples for that parameter exceed the applicable screening level prescribed in
										this Subchapter.
(3) A beneficial use shall be deemed to be fully
										supported but threatened if the use is supported currently but the appropriate state environmental agency
										determines that available data indicate that during the next five years the use may become not supported due
										to anticipated sources or adverse trends of pollution not prevented or controlled. If data from the preceding
										two year period indicate a trend away from impairment, the appropriate agency shall remove the threatened
										status.
(4) A beneficial use shall be deemed to be not supported
										for a given parameter whose criterion is based upon a short term average if at least 10% of the samples for
										that parameter exceed the applicable screening level prescribed in this Subchapter.

Current through Vol. 41, No. 20, July 1, 2024
(a)
Scope.
The provisions of this
										Section shall be used to determine whether the subcategory of Primary Body Contact of the beneficial use of
										Recreation designated in OAC 785:45 for a waterbody is supported during the recreation season from May 1
										through September 30 each year. Where data exist for multiple bacterial indicators on the same waterbody or
										waterbody segment, the determination of use support shall be based upon the use and application of all
										applicable tests and data.
(b)
Escherichia coli
										(
E. coli
).
(1) The Primary Body
										Contact Recreation subcategory designated for a waterbody shall be deemed to be fully supported with respect
										to
E. coli
if the geometric mean of 126 colonies per 100 ml is met. These values are based
										upon all samples collected over the recreation period in accordance with OAC
										785:46-15-3(c).
(2) The Primary Body Contact Recreation subcategory designated for a
										waterbody shall be deemed to be not supported with respect to
E. coli
if the geometric mean
										of 126 colonies per 100 ml is not met. These values are based upon all samples collected over the recreation
										period in accordance with OAC
										785:46-15-3(c).
