State Narrative Language For: Antidegradation
Where Hater quality exceeds levels necessary to protect beneficial uses, that quality shall be fully maintain-
ed and protected. Water quality may be lowered orvly if the state finds, after full satisfaction of the
intergovernmental coordination and public participation provisions of 10 CSR 20-6.020, that such loitered Hater
quality is necessary to allow important economic and social development. The state shall assure that there
shall be achieved the highest statutory and regulatory requirements for all nen and existing point sources and
all cost-effective and reasonable best management practices for nonpoint source control before allowing any
lowering of water quality. Such lowered water quality would only be allowable provided that:
(1) Existing instream uses are fully maintained and protected.
(2) No public health hazard is created; and
(3) There is no lowered water quality in outstanding natural resource waters or outstanding state resource
waters
State Narrative Language For: Toxics
The waters of the state shall be free from substances or conditions that have a harmful effect on human,
animal, or aquatic life.
(later contaainants shall not cause the limits in Table A in the Missouri Water Quality Standards for the toxic
fore of eetals and other toxic substances to be exceeded. Concentrations of such substances in bottom
sediaents or waters shall not harm benthic organisms and shall not accumulate through the food chain in
harsful concentrations, nor shall Food and Drug Administration maximum fish tissue levels for fish consumption
be exceeded. Wore stringent criteria lay be imposed if there is evidence of additive or synergistic effects.
Effluent toxicity studies or site-specific instreat biological studies performed, recognized, or sanctioned by
the commission may be used to develop alternative effluent limits not based on Table A values.
Persistent, bioaccumulative, man-made toxic substances are not allowed in waters of the state.
Other potentially toxic substances for which sufficient toxicity data are not available may not be released to
waters of the state until safe levels are demonstrated through adequate bioassay studies.
State Narrative Language For: Free From
All waters of the State at all times shall be:
A. Free from substances that will cause the formation of putrescent or otherwise objectionable bottom
deposits, -
8. Free froe oil, scum and floating debris in sufficient amounts to be unsightly or deleterious.
C. Free fro« materials that cause color, odor, or other conditions in such degree as to create a nuisance. ,
D. Free fron substances or conditions that have a harmful effect on human, animal, or aquatic life.
State Narrative Language For: Mixing Zones
A. The mixing zones shall be exempted from the specific criteria for those substances that are rendered
non-toxic by dilution, dissipation, or rapid transformation. Acutely toxic concentrations of substances are
not allowed in the nixing zone. The mixing zone shall not overlap another mixing zone in such a manner that
SD-1

the laintenance of aquatic life in the body of Mater as a whole Mould be adversely affected.
B. In determining the size and location of the mixing zone for any discharge, the folloMing characteristics
lust be considered:
i. The size of the river, the volute of discharge, the streai bank configuration, the mixing velocities, and
other hydrologic or physiographic characteristics;
ii. The present and anticipated future uses of the Mater, including type of aquatic life supported; and
iii. The dilution ratio, that is, the ratio of the seven (7)-day once-in-ten (lO)-year IOM floM of the
receiving streai to the average dry weather flow of the discharge.
C. Zones of passage must be provided wherever mixing zones are allowed. As a guideline, at least three
quarters of the cross-sectional area or volume of flow of a stream should be left free as a zone of passage,,

Application of water to cropland or directly to plants that may be used for
huian or livestock consumption. Occasional supplemental irrigation, rather than
continuous irrigation, is assuted.
Maintenance of conditions to support health in livestock and wildlife.
Maintenance of conditions to sustain wart-water fish and other wart-water
aquatic life, including critical stages of reproduction and early life. It will
include wart-water sport fishing.
Maintenance of conditions to support the propagation or stocking of trout.
Activities in which there is direct huian contact with the raw surface water to
the point of complete body subtergence. The raw water tay be ingested
accidentally and certain sensitive body organs, such as the eyes, ears, and the
nose will be exposed to the water. Although the water tay be ingested
accidentally, it is not intended to be used as a potable supply unless
acceptable treatment is applied. Hater so designated is intended to be used for
swiiting, water skiing or skin diving.
Maintenance of a raw water supply which will yield potable water by public
water treattent facilities.
Hater to support various industrial uses; since quality needs will vary by
industry, no specific criteria are set in these standards.
Aquatic life criteria and Food and Drug Administration limits for fish
consumption are applicable.
Activities in which very little contact with water is assuted.
Streats that taintain permanent flow even in drought periods.
Standing water reaches of Class P Streats, including itpoundtents.
Streams that may cease flow in dry periods, but maintain permanent pools which
support aquatic life.
