Current through Register Vol. 43, No. 39, September 26, 2024
(a)
Criteria development guidance. The development of surface water quality
criteria for substances not listed in these standards shall be guided by water
quality criteria published by the EPA. If the department finds that the
criteria listed in this regulation are underprotective or overprotective for a
given surface water segment, appropriate site-specific criteria may be
developed and applied by the department, in accordance with
K.A.R.
28-16-28f, using bioassessment methods or
other related scientific procedures, including those procedures consistent with
the EPA's "water quality standards handbook," second edition, as published in
August 1994, or other department-approved methods.
(b) General criteria for surface waters. The
following criteria shall apply to all surface waters, regardless of
classification:
(1) Surface waters shall be
free, at all times, from the harmful effects of substances that originate from
artificial sources of pollution and that produce any public health hazard,
nuisance condition, or impairment of a designated use.
(2) Hazardous materials derived from
artificial sources, including toxic substances, radioactive isotopes, and
infectious microorganisms derived from point sources or nonpoint sources, shall
not occur in surface waters at concentrations or in combinations that
jeopardize the public health or the survival or well-being of livestock,
domestic animals, terrestrial wildlife, or aquatic or semiaquatic
life.
(3) Surface waters shall be
free of all discarded solid materials, including trash, garbage, rubbish,
offal, grass clippings, discarded building or construction materials, car
bodies, tires, wire, and other unwanted or discarded materials. The placement
of stone and concrete rubble for bank stabilization shall be acceptable to the
department if all other required permits are obtained before
placement.
(4) Surface waters shall
be free of floating debris, scum, foam, froth, and other floating materials
directly or indirectly attributable to artificial sources of
pollution.
(5) Oil and grease from
artificial sources shall not cause any visible film or sheen to form upon the
surface of the water or upon submerged substrate or adjoining shorelines, nor
shall these materials cause a sludge or emulsion to be deposited beneath the
surface of the water or upon the adjoining shorelines.
(6) Surface waters shall be free of deposits
of sludge or fine solids attributable to artificial sources of
pollution.
(7) Taste-producing and
odor-producing substances from artificial sources shall not occur in surface
waters at concentrations that interfere with the production of potable water by
conventional water treatment processes, that impart an unpalatable flavor to
edible aquatic or semiaquatic life or terrestrial wildlife, or that result in
noticeable odors in the vicinity of surface waters.
(8) The natural appearance of surface waters
shall not be altered by the addition of color-producing or turbidityproducing
substances from artificial sources.
(9) In stream segments where background
concentrations of naturally occurring substances, including chlorides and
sulfates, exceed the water quality criteria listed in table 1a of the "Kansas
surface water quality standards: tables of numeric criteria," as adopted by
reference in subsection (e), the existing water quality shall be maintained,
and the newly established numeric criteria shall be the background
concentration. Background concentrations shall be established using the methods
outlined in the "Kansas implementation procedures: surface water quality
standards," as adopted by reference in
K.A.R.
28-16-28b, and available upon request from
the department.
(c)
Application of criteria for designated uses of surface waters.
(1) The numeric criteria in tables 1a, 1b,
1c, and 1d of the "Kansas surface water quality standards: tables of numeric
criteria" shall not apply if the critical low flow is less than 0.03 cubic
meter per second (1.0 cubic foot per second) for waters designated as expected
aquatic life use waters and restricted aquatic life use waters, unless studies
conducted or approved by the department show that water present during periods
of no flow, or flow below critical low flow, provides important refuges for
aquatic life and permits biological recolonization of intermittently flowing
segments.
(2) The numeric criteria
in tables 1a, 1b, 1c, and 1d of the "Kansas surface water quality standards:
tables of numeric criteria" shall not apply if the critical low flow is less
than 0.003 cubic meter per second (0.1 cubic foot per second) for waters
designated as special aquatic life use waters, unless studies conducted or
approved by the department show that water present during periods of no flow,
or flow below critical low flow, provides important refuges for aquatic life
and permits biological recolonization of intermittently flowing
segments.
(d) Criteria
for designated uses of surface waters. The following criteria shall apply to
all classified surface waters for the indicated designated uses:
(1) Agricultural water supply use. The water
quality criteria for irrigation and livestock watering specified in table 1a of
the "Kansas surface water quality standards: tables of numeric criteria" shall
not be exceeded outside of mixing zones due to artificial sources of
pollution.
(2) Aquatic life support
use.
(A) Nutrients. The introduction of plant
nutrients into streams, lakes, or wetlands from artificial sources shall be
controlled to prevent the accelerated succession or replacement of aquatic
biota or the production of undesirable quantities or kinds of aquatic
life.
(B) Suspended solids.
Suspended solids added to surface waters by artificial sources shall not
interfere with the behavior, reproduction, physical habitat, or other factors
related to the survival and propagation of aquatic or semiaquatic life or
terrestrial wildlife. In the application of this provision, suspended solids
associated with discharges of presedimentation sludge from water treatment
facilities shall be deemed noninjurious to aquatic and semiaquatic life and
terrestrial wildlife if these discharges do not violate the requirements of
paragraphs (b)(6) and (8) and paragraph (d)(2)(D).
(C) Temperature.
(i) Heat from artificial sources shall not be
added to a surface water in excess of the amount that will raise the
temperature of the water beyond the mixing zone more than 3°C above natural
conditions. Additionally, a discharge to a receiving water shall not lower the
temperature of the water beyond the mixing zone more than 3°C below natural
conditions. The normal daily and seasonal temperature variations occurring
within a surface water before the addition of heated or cooled water from
artificial sources shall be maintained.
(ii) Temperature criteria applicable to
industrial cooling water recycling reservoirs that meet the requirements for
classification specified in
K.A.R.
28-16-28d shall be established by the
secretary on a case-by-case basis to protect the public health, safety, or the
environment.
(D) Toxic
substances.
(i) Conditions of acute toxicity
shall not occur in classified surface waters outside of zones of initial
dilution, nor shall conditions of chronic toxicity occur in classified surface
waters outside of mixing zones.
(ii) Acute criteria for the aquatic life
support use specified in tables 1a, 1b, and 1c of the "Kansas surface water
quality standards: tables of numeric criteria" shall apply beyond the zone of
initial dilution. Chronic criteria for the aquatic life support use specified
in tables 1a, 1b, and 1d of the "Kansas surface water quality standards: tables
of numeric criteria" shall apply beyond the mixing zone.
(iii) If a discharge contains a toxic
substance that lacks any published criteria for the aquatic life support use,
or if a discharge contains a mixture of toxic substances capable of additive or
synergistic interactions, bioassessment methods and procedures shall be
specified by the department to establish whole-effluent toxicity limitations
that are consistent with paragraph (d)(2)(D)(i).
(3) Domestic water supply use.
(A) Except as provided in paragraph
(d)(3)(B), the criteria listed in table 1a of the "Kansas surface water quality
standards: tables of numeric criteria" for domestic water supply use shall not
be exceeded at any point of domestic water supply diversion.
(B) In stream segments where background
concentrations of naturally occurring substances, including chlorides and
sulfates, exceed the domestic water supply criteria listed in table 1a of the
"Kansas surface water quality standards: tables of numeric criteria," due to
intrusion of mineralized groundwater, the existing water quality shall be
maintained, and the newly established numeric criteria for domestic water
supply shall be the background concentration. Background concentrations shall
be established using the methods outlined in the "Kansas implementation
procedures: surface water quality standards," which is adopted in
K.A.R.
28-16-28b.
(C) Any substance derived from an artificial
source that, alone or in combination with other synthetic or naturally
occurring substances, causes toxic, carcinogenic, teratogenic, or mutagenic
effects in humans shall be limited to nonharmful concentrations in surface
waters. Unless site-specific water quality conditions warrant the promulgation
of more protective criteria under the provisions of subsection (a) of this
regulation and
K.A.R.
28-16-28f, maximum contaminant levels for
toxic, carcinogenic, teratogenic, or mutagenic substances specified in
40 C.F.R.
141.11,
141.13,
and
141.61
through
141.66,
as in effect on July 1, 2012, shall be deemed nonharmful.
(D) The introduction of plant nutrients into
surface waters designated for domestic water supply use shall be controlled to
prevent interference with the production of drinking water.
(4) Food procurement use.
(A) Criteria listed in table 1a of the
"Kansas surface water quality standards: tables of numeric criteria" for food
procurement use shall not be exceeded outside of a mixing zone due to any
artificial source of pollution.
(B)
Substances that can bioaccumulate in the tissues of edible aquatic or
semiaquatic life or wildlife through bioconcentration or biomagnification shall
be limited in surface waters to concentrations that result in no harm to human
consumers of these tissues. For bioaccumulative carcinogens, surface water
concentrations corresponding to a cancer risk level of less than 0.000001
(10-6) in human consumers of aquatic or semiaquatic
life or wildlife shall be deemed nonharmful by the department and adopted as
food procurement criteria. Average rates of tissue consumption and lifetime
exposure shall be assumed by the department in the estimation of the cancer
risk level.
(5)
Groundwater recharge use. In surface waters designated for the groundwater
recharge use, water quality shall be such that, at a minimum, degradation of
groundwater quality does not occur. Degradation shall include any statistically
significant increase in the concentration of any chemical or radiological
contaminant or infectious microorganism in groundwater resulting from surface
water infiltration or injection.
(6) Industrial water supply use. Surface
water quality criteria for industrial water supplies shall be determined by the
secretary on a case-by-case basis to protect the public health, safety, or the
environment.
(7) Recreational use.
(A) General. The introduction of plant
nutrients into surface waters designated for primary or secondary contact
recreational use shall be controlled to prevent the development of
objectionable concentrations of algae or algal by-products or nuisance growths
of submersed, floating, or emergent aquatic vegetation.
(B) Primary contact recreation for classified
surface waters other than classified stream segments. A single sample maximum
or a geometric mean of at least five samples collected during separate 24-hour
periods within a 30-day period shall not exceed the criteria in table 1j of the
"Kansas surface water quality standards: tables of numeric criteria" beyond the
mixing zone.
(C) Secondary contact
recreational use for classified surface waters other than classified stream
segments. A single sample maximum or a geometric mean of at least five samples
collected during separate 24-hour periods within a 30-day period shall not
exceed the criteria in table 1j of the "Kansas surface water quality standards:
tables of numeric criteria" beyond the mixing zone.
(D) Primary contact recreation for classified
stream segments. At least five samples shall be collected during separate
24-hour periods within a 30-day period. A geometric mean analysis of these
samples shall not exceed the criteria in table 1i of the "Kansas surface water
quality standards: tables of numeric criteria" beyond the mixing
zone.
(E) Secondary contact
recreation for classified stream segments. The following criteria shall be in
effect from January 1 through December 31 of each year:
(i) At least five samples shall be collected
during separate 24-hour periods within a 30-day period.
(ii) A geometric mean analysis of the samples
specified in paragraph (d)(7)(E)(i) shall not exceed the criteria in table 1i
of the "Kansas surface water quality standards: tables of numeric criteria"
beyond the mixing zone.
(F) Wastewater disinfection. Wastewater
effluent shall be disinfected if the department determines that the discharge
of nondisinfected wastewater constitutes an actual or potential threat to
public health. Situations that constitute an actual or potential threat to
public health shall include instances in which there is a reasonable potential
for the discharge to exceed the applicable criteria supporting the assigned
recreational use designation or if a water body is known or likely to be used
for either of the following:
(i) Primary or
secondary contact recreation; or
(ii) any domestic water supply.
(8) Multiple uses. If a
classified stream segment or classified surface water other than a classified
stream segment is designated for more than one designated use according to
K.A.R.
28-16-28d, the water quality of the
classified stream segment or classified surface water other than a classified
stream segment shall meet the most stringent of the applicable water quality
criteria.
(e) Tables. The
numeric criteria for the designated uses of classified surface waters shall be
the numeric criteria specified in the department's "Kansas surface water
quality standards: tables of numeric criteria," dated March 2, 2021, which is
hereby adopted by reference.
