For a general guide, with respect to fish
toxicity, receiving waters outside the
mixing zones should not have a concentration
B of nonpersis tent toxic materials exceeding
1/10 of ~he 96-hour TLm, where the bioassay -
.
is mace using rish indigenous to tne receivinc
B ' waters. Similarly, for persistent toxicants,
M the concentrations should not exceed 1/20
of the 95 -hour TLm.
I
In general, for evaluations of toxicity,
bioassay techniques will be selected as
B suited to the purpose at hand. However,
M bioassays. will be conducted under wa~er
quality conditions (-emperature , hardness,
B ' pH , salinity, dissolved oxygen, etc.) which
B approximate those of che stream as closely
I
_ 9 . As detailed studies are completed, limiting
nutrients identified, and the feasibility
B of. controlling excessive standing crops

nutrient limitations is determined, it is

as practical.

anticipated that nutrient standards - will
be established on ,t:he surface waters of the
State. Such decisions will be made on a
case-by-case basis by the Board after proper
hearing and public participation. The
establishment7of a schedule for decisions
as to the need for nutrient standards for
specific waters and what standards should be
adopted is not feasible at: this time.
10. The surface waters of the Stace shall be
maintained so that no oil, grease, or related
residue will produce a visible ^fiim of oil
or globules of grease on the surface, or
coa- the banks and bctcoms of the watercourse
VII. Numerical Criteria
~ The numerical criteria apoly to the specific
waters identified. Stream standards apply only to
waters where standards are established and specifically
apply with respect to substances attributed to waste
discharges or the activities of man as opposed to
natural phenomena.

I
Chemical concentration parameters, with the
exception of dissolved oxygen and pH, apply to the
m approximate mid-point of the segm.errt with reasonable
im gradients applying toward segment boundaries. The
numerical values shown reorasent arithmetic average
conditions over a period of one year.- whenever an
B unusual chemical concentration is found/ an investiga-
tion of its origin will be made and such action as is
warranted initiated. Salinity levels in estuarine
B areas are discussed in. Section X, 3, Sstuarine Salinity
The dissolved oxygen values are minimum.
values which are apolicable excect as cualified in
Section VIII. For short periods of time, diurnal
variations of 1.0 mg/1 below the standard specified
M in the table shall be allowed for not more ~han 3
hours during any 24-hour period.
. __ The pH range represents maximum and minimum
B conditions throughout the segment except as qualified
in Section VIII.
The temperature limitations are intended to
B be applied with judgment and are applicable ~o the
waters specifically identified herein with the cuali-

standards are composed of two parts_, a maximum tempera-
ature and a maximum temperature differential attribtu-
able to heated effluents.
Natural high temperatures, in excess of 96°?,
occur regularly in Texas waters during the summer
'
months. For example, 2.3% of United States Geological
Survev measurements made during the summer months on
the Double Mountain Fork of the Brazos River near
\
Aspermont, Texas/ during the period 1953 through 1971
exceeded 96°?. It is consequently concluded -hat the
90°F maximum temperature suggested by- the'National
-S . ,*
' UV
Technical Advisory Committee is not applicable to
Texas conditions.
Tidal River Reaches, Bay and Gulf Wafers:
Fall/ Winter/ Spring Summer
Maximum Temp. Diff. 4°F 1.5°F
.Maximum Temperature 95°? 95'F
Bacteriological water quality standards
consist of two parts: (1) a measure of general quality,
and (2) a limit on variations from the general quality.
For all waters excepc gulf and bay waters,
the measure of general quality is the logarithmic mean

(geometric mean) of fecal coiiform determinations.
The number specified in the tables applies -o the
logarithmic mean (geometric mean) of data from a
representative sampling of not less than 5 samples
collected over not more than 30 cays. All aspects
of the sampling shall be such that a truly represen-
tative rasul- is obtained. For rou~ine observation
and evaluation of water quality, lesser numbers of
samples collected over longer oeriods will be used.
In bay waters (exclusive of bay waters in the buffer
zone), the number specified in -he tables aooiies to
the median total coliform density as specified in che
"National Shellfish Sanitation Program Manual of
Operation, Part 1, Sani.-a.tion of Shellfish Growing
Areas," 1965 Revision, or lacest revision.
The limit on variations from the general
bacteriological quality on all waters except gulf and
bay wafers is a fecal coliform density which shall not
be equaled or exceeded in more than 10% of che
samples. This dens it*/ is twice the numerical criteria
specified in the table. In the instance of gulf and
bay waters (exclusive of the buffer zone), the criteria
for shellfish growing water shall apply.
-------
Buffer Zones in 3ay and Gulf Waters
For all bay and gulf waters/ exclusive of
those contained, in river or coastal basins as defined
in Section IV, a buffer zone of 1,000 feet measured
from the shoreline at_ordinary high ride is hereby
established. In this zone/ the bacteriological require-
ments enumerated in other sections of these standards
shall not apply. In these zones, the logarithmic mean
(geometric mean) density of 'fecal coliform organisms
shall not exceed 200/100 ml, nor shall more than 10%
of -che total samples exceed 400/100 ml. The foregoing
percentages are applicable when examining data from
not less than 5 samples collected over noc more than
30 days. For routine observation and evalua-ion of
water crualitv, lesser numbers of samoles collected
over loncer oeriods will be used.

Antidegradaticu Statement
It is the policy of the Louisiana Stream Control
Commission that all interstate waters and intrastace waters,
portions thereof, and coastal waters whose existing quality
exceed the approved water quality standards will be maintaine;
at their existing high quality unless the stata chooses after
full satisfaction of the intergovernmental coordination and
public participation provisions of the State Continuing
Planning^ Process to allow lower water quality as a. result of
necessary and justifiable econoniic and/or social development,
and further that s-ach changes will not interfere with or
become injurious to the existing instrean water uses. The
Louisiana Stream Control Ccimission will disapprove any waste
discharge that will cause wacer quality degradetion' of inter-
state waters and intrastate waters, portions thereof, and
the coastal waters of Louisiana below the standards adopted
by the State of Louisiana and approved by the United States
Environmental Protection Agency without complying with the
Federal and Stata of Louisiana laws applicable to the
attainment of water quality standards.

Any industrial, public or private project or development
that would constitute a new source of pollution
or an increased source of po-ilu~ion to any of the waters
in Louisiana will be required, as part of the initial project
design, to provide the highest and best degree of waste treat-
ment available under existing technology consistent with the
best practice in the area affected under the condition applicable
to the nro^ect or deveic ir.ent Further there shall be achieved
the highest statutory and regulatory requirements for ail
existing point sources and feasible management or regulatory
programs pursuant to Section 203 of Public Law 92-500 for
nonpoint sources, both existing and proposed. Additionally,
no degradation shall be allowed in high quality waters which
constitute an outstanding national resource, such as waters
of national and state parks and wildlife refuges, waters in
the scate scenic rivers system and waters of exceptional
recreational or ecological significance. This policy and
implementation method shall be consistent with Secticn 315
of 92-500 (Re: thermal discharges). Consistent with the
provision of the Federal Water Pollution Con-rol Act as
amended (1972) the Louisiana Stream Control Commission will
informed of its activities and will furnish the 'Jniied
States Environmental Protection Agency informational
reports, in such form as the Administrator of the United
States Environmental Protection Agency may, from time to
time, reasonably require to carry out: his function under
-------
the Federal Water Pollution Control Act Amendments of 1972.
The Louisiana Scream. Control Commission will consult and
cooperate with the United States Environmental Protection
Agency on matters that are proper consideration of the
Federal Agency; the United States Environmental Protection
Agency will reciprocate in matters ihat are a proper con-
sideration of the Louisiana Stream Control Commission.
General Criteria
The following ceneral criteria are acolicable to the
surface waters of the State of Louisiana and specifically
apply with respect to substances attributed to waste dis-
charges or the activities of man as opposed to natural
ohencmena. " '
Natural waters may, on occasion, have characteristics
outside the limits established, by these criteria; in which
case, these criteria do not aopiy. The criteria adcoted
herein relate to the condition of water as affected by
waste discharges or man's activities.
These general criteria do not supercade specific ax-
ceotions to any one or more of the foliowinc if the exception
is specifically stated in a specific water quality standard.
Ail waters of the state shall be capable of supporting_
desirable diversified acruatic life consisting of i,£icenou3
-'/>'
species of fish, shell fish and wildlife.

The waters of the state shall be maintained
in an aesthetically attractive condition and
shall ir.aet the generally accepted aesthetic
qua!ifications.
All waters shall be free from substances attributable
to. wastewater or other discharges that:
(1) settle to form objectionable deposits; -
(2) float as debris, scum, ail, or other matter.
to form nuisances;
(3) produce objectionable color, odor, taste, or
turbidity;
(4) injure or are toxic or produce advers physiological
response in humans, animals, fish, shellfish,
wildlife, or plants; and,
(5) produce undesirable or nuisance aquatic life.
True color shall net be increased to the extent that
it will interfere with present usage and projected
future use of the streams and water bodies.
(1) waters shall be virtually free from substances
producting objectionable color for aesthetic
' purposes;
(2} the source of supply should not exceed 75 color units
on the platinumrcobal t scale for domestic water
supplies; and
(3) increased color (in combination with turbidity) shall!
not reduce the depth of light penetration by more

visible turbidity, solids or scum, nor shall there
be any formation of slimes, bottom deposits or
s-ludge "banks attributable to waste discharges from
municipal, industrial, or other sources including
agricultural practices.
Settleable and suspended solids shall not reduce
the depth of light penetration by mere than
10 percent from the seasonably established
norm.
(4) TASTE AMD ODOR Tasta and odor producing substances shall be
limited to concentrations in the waters of the
state that wilT not interfere 'with the production -
of potable water by reasonable water treatment
methods, or impart unpalatable flavor to food
fish, including shellfish, or result in offensive
odors arising from the waters, or otherwise
interfere with the reasonable use of the waters.
(5) TOXIC SUBSTANCES None present in quantities that alone or in
combination will be toxic to animal or plant life.
In all cases the level shall not exceed the
TIM 95/10. Sicassay techniques will be used in
evaluating toxicity utilizing iretncds and species

WATER USE! CLASSIFICATION:
Policy:
It is the policy of the State of Louisiana that all state waters
should be protected for recreational uses in and/or on the water and
for the preservation and propagation of desirable species of aquatic
biota such as indigenecus species of fish,she! 1 fish and wildlife.
Use and value of water for public water supplies, agricultural, industrial,
and other purposes as well as navigation, shall also be considered in
setting standards, but in no case, except as provided below, shall
the criteria supporting these uses be permitted to interfere with
recreational uses and the preservation of indigenous soecies of fish, shell-
fish, wildlife and desirable species of other aquatic biota.
Recreational uses will be specified as either "primary con-act" or
"secondary contact." Desirable species of fish, shellfish, wildlife and
other aquatic biota will be specified as '''fresh warm water," or "marine
waters." All future designations of stream uses and their associated
criteria must, at a minimum, adhere to these classifications except as
provided below.
Exceoticns:
Some waters, because of naturally occurring poor quality, man-made
pollution or technological limitations .mcy qualify for an excepted classi-
fication. This determination, however, will be made on a case-by-case
basis following the analysis of each such area. In a"! cases where
exceptions are proposed the concurrence of the Regional Administrator of
the United States SnvironmentalProtection A-sncv will first be obtained.
-------
-In any case where the exception is based on technological 1 imi taticns , the
exception will be temporary , i.e., the exception will be reviewed at least
every tnree years as required by Section 303 (c) of Public Lav/ 32-500 to
determine the possibility of upgrading.
In applying this policy, the terms "recreational uses" and "desirable
species of aquatic biota11 will be given common sense application. The
existence of man-made pollution will be reviewed as a problem to be
solved, not as an impediment against assigning, this use classification.
"Desirabl e Scecies of Aquatic Biota" refers to a diverse and naturally
occurring range of aquatic biota and not to species that exist in the area
in question in disproportionate numbers as a result of marr's waste dis-
charges.
The most stringent criteria specified for each parameter shall be

CLASS 8.: FISH, WILDLIFE AND QTf!£R AQUATIC AND SEMI -AQUATIC LIFE, SECONDARY
CONTACT RECREATION AND OTHER USES
A surface raw water source, suitable for the growth and propagation of
fish, other aquatic and semi -aquatic life bo'h marine and fresh water;
waterfowl, fur bearers; and wildlife. This water may be used for warm
water fish habitat, wildlife habitat, and other similar uses. This
water is also suitable for secondary waier contact recreation such as
fishing, wading, boating, or activities where ingestion of the water 'is
not probable or as a raw water source public water supply, agricultural,
industrial and navigational uses.
Criteria for Class A and 3 are equal to or more stringent than "hose
\
applicable for public water supply use as stated in the report of the
National Technical Advisory Committee to the Secretary of the Interior on
the Water Quality Criteria. However, when a water boyy is' used as 'a public
" -*. '
* > * \^f'
water supply it shall be identified as such in the standards for the
stream and/or segment where the use occurs.
NUMERICAL CRITERIA
These numerical criteria apply to the specific waters of Louisiana
identified in the tables, their navigable cr'bucaries, distributaries and
ancillary streams and waterbcdies (unless such tributaries, distributaries
and ancillary streams or wa~erbodies are specifically identified and nave
numerical standards listed in -his book) and specifically apply with respect
to substances or conditions attributed to waste discharges or activities
of man as opposed to natural phenomena.
pH- The pM range represents minimum and maximum conditions throughout the
segment with reasonable gradients applying cowards segment boundaries.

In all cases the pH shall fall within the range of 5.0 to- 9.0 unless
otherwise specified in the tables. i\'o discharge of wastes shall cause
the pH of the water body to vary by more than one (1) pH unit within
the specified pH range for that segment where the discharge occurs.
(This does not apply in the Mixing Zp_r,e_.)
CHLORIDES, SULFATES & DISSOLVED SOLI OS-
Values for these parameters apply to the approximate midooint of the
stream segment with reasonable gradients applying towards segment
boundaries. Values listed in the standards in general represent the
arithmetic mean of existing data plus one standard deviation.
DISSOLVED GXYGEN-
The following Dissolved Oxygen values represent minimum values for the type
of water specified. These values shall apply at all times except in
naturally dystrcphic waters or where natural conditions cause the
Dissolved Oxygen to be depressed. For short periods of time,
diurnal variations below the standard soecified may occur. However,
no waste discharge or activity of man shall lov.'er the Dissolved Oxygen
concentration to trie point where the-diurnal variation falls oelcw
the specified minimum.
FRESH WA7ER-
For a diversified warm water biota including game fish, the daily D.O.
concentration shall be above 5 ,mg/l assuming normal seasonal and daily
variations are above this concentration. However, they may range
between 5 and 4 mg/1 for short periods of time during a 24-hcur period,
provided the water quality is favorable in all otner,respects.
eSTUARINE S'ATER-
Dissolved oxygen concentrations in estuaries and tidal tributaries shall
not be less than ^mg/1 at any time or place except in naturally
dystrcphic waters, or where natural conditions cause D.O. to be
depressed.
COASTAL WATER-
Dissolved Oxygen concentration in sur-'ace coastal waters shall be
greater than 3mg/l except when the uov.'el lings and other natural
phenomena .may cause this value to be depressed.
TEMPERATURE-
The temperature standards enumerated in the tables, in most cases,
represent maximum values obtained from existing data. However, in a
few cases a limited number of unusually high temperatures in the range
of 3^-28" have been deleted as it is felt that tnase values were
recorded during conditions of unseasonably high temperatures and/or
unusually low flows or water levels, and, therefore, do not represent
normal maximum temoeraturss.
-------
In order to protect a diversified warn water biota including gams
fish, the following temnerature criteria shall apoly (except
when natural conditions cause the temperature to be raised above
these 1imits).
The standard shall consist" of tv/o parts, a temperature differential
and a maximum temperature. The temperature differential represents
the maximum perrnissable rise above ambient conditions. There
shall be no addition of artificial heat once the ambient
temperature reaches the maximum temperature specified in the
standards.
FRESH WATER- Temperature differential
> \
1} Maximum of 53F (2.S°C) rise above ambient for streams and
rivers.
2) Maximum of 3°F (1.7aC) rise above ambient for lakes and
reservoirs.
MAXIMUM TEMPERATURE- 903C (32.2°C) except where otherwise
listed in the tables or due to natural conditions.
ESTUARIES AND COASTAL WATERS - Temperature differential
-s
*,.
1) Maximum of -3F (2.2>3C) rise above amoierb"'during the period
October through May.
2} Maximum l.S°F (C.33°C) during the period June through
September.
MAXIMUM TEMPERATURE - 95°F (35'C) excect when natural conditions
elevate temperature above this level.
These temperature criteria shall not apply to privately owned
reservoirs, or reservoirs constructed solely for industrial cooling purposes.

or a combination of both in order to achieve the stream sanitary quality
required for the most restrictive stream water usage.
The tables in this .document listing applicable criteria for each
individual Louisiana stream segment designate one of the following four
standards as applicable according to present and anticipated usage of the
segment waters:
Standard =1 PRIMARY CONTACT RECREATION- 3ased or, a minimum of not less
than 5 samples taken over not: more than a 20-day period,
the fecal conform content shall not exceed a log'mean of
2QQ/10Q ml. nor snail more than 10 percent of the total
samples during any 30-day period exceed 400/100 ml.
Standard = 2 SECONDARY CONTACT RECREATION- 3ased on\ a minimum of not
less than 5 samples taken over not more 'tnan a 30-day
period, the fecal coliform content shall not exceed a log
mean of 1,000/lOCml. nor shall more than 10 percent of tne
total samples during any 30-day period equal or exceed
2,000/lOCml. 1
A.
Standard .v.3 PUBLIC WATER SUPPLY- The monthly arithmetic average of
total coliform MPN (most procaole number) shall not exceed
10,000/lOCml. nor shall the monthly arithmetic average of
fecal coliforms exceed 2,000/lCCml.
Standard =4 SHELLFISH PROPAGATION- The monthly total coliform meaiar,
MPN (most probable number) shall not exceed 70 oer ICCml.
and not more than 10 percent of the samples ordinarily
exceed an MPN of 22C/'lCCnil .
-------
APPLICATION OF STANDARDS
Flow Conditions: Except where indicated below the water
quality standards specified herein shall apply during all flow conditions.
Chem i c a1 Par ame t e rs: The chemical parameters (except Dissolved
Oxygen) represent maximum values for the segment specified in the tables.
These standards shall apply at all times except when natural conditions
cause them to be exceeded.
Pis solved_0xycen: The Dissolved Oxygen values represent minimuml
values for the type of water specified. These values shall apply at all times
except in naturally ays trophic waters or where natural conditions cause the |
Dissolved Gxycan to be depressed; for short periods of time diurnal variations
below the standard specified may occur. However, no waste discharge or activicy
of man shall lower the Dissolved Oxygen concentration to the point where |
diurnal variation falls below the specified minimum. .
TefHoerature: - The temoeracure standards reoresenu maximum
I
values and shall apply in all cases except when unusual natural conditions .
of extremely low flow and unseasonably high temperatures may cause the establisnec
temperature standard to be exceeded. There shall be no addition of artificial I
heat once the ambient temperature reaches the maximum specified in the standards.
I
General Criteria and Other I
Parameters: The general criteria and other criteria no" '
specifically discussed above shall apply at all times except when natural
conditions may cause the standard to be exceeded.
I
-------
mm Mixing Zones: The total area and/or volume of a stream
assigned to mixing zones will be limited to that which will: (1) not interfere
| with biological communities or populations of important species to a degree
| which is damaging to the ecosystem; (2) not diminish other beneficial uses
disorooortionatelv.
I
Zones of Passage: In river streams, reservoirs, lakes, estuaries
and coastal waters, zones of passage are continuous water routes of the volume,
H area and quality necessary to allow passage of free-swimming and drifting
organisms with no significant effects produced on their populations. These zones
. must be provided wherever mixing zones are allowed.
Because of varying local physical and chemical
conditions and biological phenomena no single value can be given on the percentac
of river (or stream) width necessary to allow passage of criticial free-swimming
and drifting organisms so that negligible or no effects are produced on their
populations. As a guideline and except when otherwise specified by the Louisiana
H Stream Control Commission in a valid waste discharge permit the Mixing Zone will
be limited to no more than 1/4 of the cross sectional area and/or volume cf rlcw
of stream or estuary, lea vine at least 3/4 free as a zone of oassage.
I
I
C.A-C.I I I i
he water quality standards will not apply to:
(1) Effluents
(2) With the exception of- the general criteria the water quality criteria
will not apply to water in mixing zones as defined above or in a valid
waste discharge permit from the Louisiana Stream Control Commission an
a National Pollution Discharge Elimination System Permit.

B. "Off-shore waters" means all coastal waters beyond the limits defined
for "near shore waters."
C "Coastal waters" includes "near shore waters," "off-shore waters,"
and all waters that are subject to the ebb and flow of the tide.
D. "Best available demonstrated pollution control technology" means that
treatment or control necessary to achieve requirements established
pursuant to statutes and regulations of the State of Hawaii and to the
Federal Water Pollution Control Act, as amended.
Section 3. CLASSIFICATION OF WATER USES
A. Classification of Coastal Water Uses
Coastal waters are classified in accordance with the uses to be
protected in each class as follows:
1. Class A A waters
The uses to be protected in this class of waters are oceanographic
research, the support and propagation of shellfish and other marine
life, conservation of coral reefs and wilderness areas, compatible
recreation, and aesthetic enjoyment.
It is the objective of this class of waters that they remain in as nearly
their natural, pristine state as possible with an absolute minimum of
pollution from any source. To die extent possible, the wilderness
character of such areas shall be protected. No zones of mixing will
be permitted in these waters.
The classification of any water area as Class AA shall not preclude
other uses of such waters compatible widi these objectives and in
conformance with the standards applicable to them.
2. Class A waters
The uses to be protected in this class of waters are recreational
(including fishing, swimming, badiing, and other water-contact
sports), aesthetic enjoyment, and the support and propagation of
aquatic life.
It is die objective for this class of waters that their use for recrea-
tional purposes and aesthetic enjoyment not be limited in any way.
Such waters shall be kept clean of any trash, solid materials or oils,
and shall not act as receiving waters for any effluent which has not
received the best degree of treatment or control practicable under
existing technology and compatible with the standards established for
this class.
3. Class B waters
The uses to be protected in this class of waters are small boat
harbors, commercial and industrial shipping, bait fishing, compatible
recreation, die support and propagation of aquatic life, and aesthetic
enj ovm.eru.--~ -

It is the objective for this class of waters that discharges of any
pollutant be controlled to the maximum degree possible and that
sewage and industrial effluents receive the best degree of treatment
control practicable under existing technology and compatible with the
standards established for this class.
The Class B designation shall apply only to a limited area next to
boat docking facilities in bays and harbors. The rest of the water area
in such bay or harbor shall be Class A unless given some other speci-
fic designation in Section 5.
B. Classification of Fresh Water Uses
Fresh waters are classified in accordance with die uses to be protected
as follows:
1. Class 1 waters ; _.
The uses to be protected in this class of waters are drinking; water
supply, food processing, die support and propagation of aquatic
life, and compatible recreation.
It is the objective of this class of waters that they remain in as
nearly their natural state as possible with an absolute minimum of
pollution from any source. To die extent possible, die wilderness
character of such areas shall be protected. Waste discharges into these
waters are prohibited.
2. Class 2 waters
The uses to be protected in this class of waters are bathing, swim-
ming, the support and propagation of aquatic life, compatible recrea-
tion, and agricultural and industrial water supply.
It is the objective for this class of waters that their use for
recreational purposes, propagation of fish and odier aquatic life,_,and
agricultural and industrial water supply not be limited in any way.
Such waters shall be kept clean of trash, solid materials or oils, andr
shall not act as receiving waters for any effluent which has: not re-.
ceived the best degree of treatment or control practicable under
existing technology and compatible with the standards established
for diis class.
Section 4. ZONES OF MIXING : I
Zones of mixing for die assimilation of municipal, agricultural,.and
trial discharges which have received die best degree of treatment or control prac-
ticable under existing technology are recognized as necessary..-_ - ::: 7-__
' It is the objective of this limited zone to provide for a current realistic
means of control over such discharges and at the same time achieve the highest-
attainable level of water quality. i .... - _ - -

GENERAL POLICY OF WATER QUALITY STANDARDS
It is the public policy of this state to conserve the waters of the state, -and to
protect, maintain, and improve the quality thereof for drinking water supply,
and food processing, for the growth, support and propagation of shellfish, fish
and other desirable species of marine and aquatic life, for oceanographic
research, for the conservation of coral reefs and wilderness areas, and for
domestic, agricultural, industrial, recreational, and other legitimate uses; and to
provide that no waste be discharged into any waters of this state without first
being given the degree of treatment necessary to protect the legitimate bene-
ficial uses of such waters; and to provide for the prevention, abatement, and
control of new and existing water pollution; and to cooperate with the federal
government in carrying out these objectives.
Therefore, waters whose qualities are higher than established Water Quality
Standards shall not be lowered in quality unless it has been affirmatively
demonstrated to the Director that such change is justifiable as a result of
necessary economic or social development and will not interfere with or
become injurious to any assigned uses made of, or presently in, such waters.
Any industrial, public, or private project or development which could constitute a
new source of pollution or an increased source of pollution will be required, as
part of the initial project design to provide the highest and best degree of waste
treatment practicable under existing technology. In implementing the policy of
this paragraph as it relates to water under federal jurisdiction, the Administrator
of the Environmental Protection Agency will be kept advised and provided with
such information as he will need from time to time to protect the interests of the
United States and the authority of the Administrator in maintaining high
quality of the waters of the United States.

2. Floating debris, oil, grease, scum, and other floating materials;
3. Substances in amounts sufficient to produce taste or odor in the water
or detectable off-flavor in the flesh of fish, or in amounts sufficient
to produce objectionable color, turbidity, or other conditions in the
receiving waters;
4. High temperature, biocides, pathogenic organisms, toxic, corrosive,
or othe"r deleterious substances at levels or combinations sufficient to
be toxic or harmful to human, animal, plant or aquatic life .or in
amounts sufficient to interfere with any beneficial use of the water.
As a minimum, evaluation by use of a 96-hour bioassay as described in
the most recent edition of Standard Methods for the Examination
of Water and Wastewater shall be conducted. Survival of test or-
ganisms shall not be less than that in controls which utilize appro-
priate experimental water;
5. Substances and conditions or combinations thereof in concentrations
which produce undesirable aquatic life. :
All waters shall also be free from soil particles resulting from erosion
on land involved in earthwork, such as the construction of public works;
highways; subdivisions; recreational, commercial, or industrial develop-
ments; or the cultivation and management of agricultural lands. This
standard shall be deemed met if it can be shown that the land on
which the erosion occurred or is occurring is being managed in accord-
ance with soil conservation practices acceptable to the Director, and that
a comprehensive conservation program is being actively pursued, or that
the discharge has received the best degree of treatment or control
practicable under existing technology. The determination of compliance
with the standard shall be made by the Director, consistent with the
Hawaii Administrative Procedure Act and the Rules of Practice and

in accumulation of radioactivity in plants or
animals that result in a hazard to humans or
harm to aquatic life.
The concentration of radioactive materials
present in fresh, estuarine, and marine waters
shall be less than those that would require restric-

These water quality criteria are baaed upon the best currently available data.
It is possible that studies planned to be made in connection with the implementa-
tion program may prove them to be either inadequate or unattainable. For this
reason, they will be subject to periodic review and, where necessary, to change.
Any change will be made only after public hearing, held in compliance with the
Hawaii Administrative Procedure Act and the Rules of Practice and Procedure of
the Department of Health.
Section 7. ESTABLISHMENT, RENEWAL, AND TERMINATION
OF ZONES OF MIXING
A. Every application for a zone of mixing shall be made on forms furnished
by the Director and shall be accompanied by a complete and detailed
description of present.conditions, how present conditions do not con-
form to standards, and such other information as the Director may
prescribe by rules and regulations.
B. Each application for a zone of mixing shall be reviewed in light of the
descriptions, statements, plans, histories, and other supporting informa-
tion as may be submitted upon the request of the Director, and the effect
or probable effect upon the water quality standards established pursuant
to this Chapter.
C. Whenever an application is approved, the Director shall establish the
zone of mixing taking into account protected uses of the body of water,
existing natural conditions of the receiving water, character of the ef-
fluent, and the adequacy of the design of the outfall and diffuser system
to achieve maximum dispersion and assimilation of the treated or con-
trolled waste widi a minimum of undesirable or noticeable effect on the
receiving water.
D. Approval of a zone of mixing shall be made only after a public hearing is
held by the Director in the county where the source is situated in accord-
ance with the Hawaii Administrative Procedure Act and the Rules of
Practice and Procedure of the Department of Health.
E. No zone of mixing shall be granted by the Director unless the application
and the supporting information clearly show that:
l.The continuation of the function or operation involved in the dis-
charge by the granting of the zone of mixing is in the public interest;
and
2. The discharge occurring or proposed to occur does not substantially
endanger human health or safety; and
3. Compliance with the existing water quality standards from which a
zone of mixing is sought would produce serious hardships without
equal or greater benefits to the public; and
4. The discharge occurrine or nronn«*»r) m

classified, and has received the best degree of treatment or control
practicable under existing technology or, in die case of die proposed
discharge, will receive die best available demonstrated pollution con-
trol technology, processes and operating methods.
F. Any zone of mixing or renewal diereof shall he granted widiin die
requirements of this section and for time periods and under conditions
consistent with die reasons dierefore and widiin die following limita-
tions:
1. If die zone of mixing is granted on die ground diat diere is no
practicable means known or available for die adequate prevention,
control, or abatement of die discharge involved, it shall be only until
die necessary means for prevention, control, or abatement become
practicable and subject to die taking of any substitute or alternate
measures diat die Director may prescribe. No renewal of a zone of
mixing granted under diis subsection shall be allowed widiout a
diorough review of known and available means of preventing, con-
trolling, or abating die discharge involved.
2. The Director may issue a zone of mixing for a period not exceeding
five years.
3. Every zone of mixing granted under this section shall include, but not
limited to, conditions requiring die grantee to perform effluent and
receiving water sampling and report die results of each sampling to
the Director, and a program of research to develop practicable alterna-
tives to die mediods of treatment or control in use by die grantee may
be required if such research is deemed prudent by die Director.
G. Any zone of mixing granted pursuant to diis section may be renewed
from time to time on terms and conditions and for periods not exceeding
"five years which would be appropriate on initial granting of a zone of
mixing; provided diat die applicant for renewal had met all- of the
conditions specified in die immediately preceding zone of mixing; aiid
provided furdier, diat die renewal, and die zone of mixing established
in pursuance thereof, shall provide for discharge not greater in quantity
of mass emissions than diat attained pursuant to the terms of the im-
mediately preceding zone of mixing at its expiration. No renewal shall
be granted except on application therefore. Any such application shall
be made at least sixty days prior to the expiration of the zone of mixing.
H. No zone of mixing granted pursuant to this part shall be construed to
prevent or limit die application of any emergency provisions and pro-
cedures provided by law.
I. The establishment of any zone of mixing shall be subject to the con-
currence of die U.S. Environmental Protection Agency. --~
]. The Director, on his own motion, or upon die application of any^person,
shall terminate a zone of mixing, if after a hearing, he shall determine"
-------
that the water area does not meet the basic standards applicable to all
water areas or that the zone of mixing granted will unreasonably inter-
fere with any actual or probable use of the water area or that the dis-
charge does not receive the best degree of treatment or control prac-
ticable under existing technology or that the new discharge did not
receive the best available demonstrated pollution control technology,
processes, and operating methods. Such termination shall be made
only after a hearing held by the Director on the island where the area
is situated in accordance with the Hawaii Administrative Procedure Act
and the Rules of Practice and Procedure of the Department of Health.
Upon such termination the standards of water quality applicable thereto
shall be those established for the water as otherwise classified.
K. Upon expiration of the period stated in the designation, the zone of
mixing shall automatically terminate and no rights shall become vested
in the designee.
Section 8. SEVERABILITY
If any provision of this Chapter, or its application to any person or circum-
stance, is held invalid, the application of such provision to other persons or
circumstances, and the remainder of this Chapter, shall not be affected thereby.
Section 9. EFFECTIVE DATE
This Chapter shall be effective 60 days after approval by the Governor.

TRUST TERRITORY OF THE PACIFIC ISLANDS
(Release No. 17-73)
PART 1 QFNERAL PROVISIONS
1.1 Under and by virtue of the provisions of Public Law
4C-78 of the Trust Territory, these Regulations and any further
Amendments, and any other applicable laws, the following Water
Quality Standards are hereby promulgated:
PART 2 ' POLICY
2.1 It is the policy of the Trust Territory of the Pacific
Islands that:
(a) All sewage and all wastes prior to discharge will receive the
best practicable treatment or control unless it can be demonstrated
that a lesser degree of treatment or control will provide water
quality commensurate with the uses of waters of the Territory, and
(b) Waters whose existing quality is better tfran the established""
standards as of the date on which such standards become effective
will be maintained at their existing high quality. These and other
waters of the Territory mil not be lowered in quality ^unless and
until it has been affirmatively demonstrated to the Environmental
Protection Board or its designee, and the Administrator of the -
Environmental Protection Agency that such change is justifiable as
a result of necessary economic or social development and will not
Interfere with or become injurious to any assigned-'uses made-of, or '"
presently possible, in such waters. Any industrial/ public :or-"private-
project or development which would constitute a new source of pollution
or an." increased source of pollution to high quality waters'will be
required, as part of the initial project design, to -provide the
highest- and best degree of waste treatment available under existing
technology.
(c) No direct discharges of sewage or other wastes from other than
natural causes, treated or untreated, will be permitted -into- fresh: -
.surface waters, or. fresh.ground waters of the Territory.
(d) .Discharge of any hazardous substance, such as pesticides,"herbi-
cides, etc., into any waters of the Territory is prohibited.

PAST "II WATER USES - IDENTIFICATION OF WATER FOR BENEFICIAL USES
11.1 Fresh Water. The topography and geology of the six
administrative districts in the Trust Territory vary. The 'Jlow islands"-
of Majuro are composed of low, sandy platforms, Saipan is "basically '
limestone and low sandy areas; Truk, Ponape, Palau and Yap are of
volcanic origin. In the "low islands" of Majuro, "Saipan, and similar
areas. there are no rivers. Rainfall readily percolates" through" the ~
porous coraline limestone formations to form fresh" water lenses
the major sources of water supply for these islands. On the "high "- :
volcanic islands in Ponape, Truk, Palau and Yap the soils are ~ " ,.
impermeable, resulting in numerous rivers, streams and ;a natural- ~~_ ' :
lake in Palau. Water supplies are obtained from these streams or -
springs. ;~j - = -'-'--
Realizing the expanding need for fresh, palatable
water, and the unique water sources for the various islands, it is ------ -_-
necessary to classify ail fresh surface and ground waters; for -public - : :
and domestic water supply purposes, propagation of 'fish and "aquatic-- '_-
life, esthetic enjoyment and recreation. Other beneficial uses - \2~~~
for these 'waters are industrial and agricultural water supplies.- -
11.2 Near-Shore Waters. All near- shore waters shall be
protected for industrial water supplies, propagation of~fish and-
other aquatic life (including waters reserved for -conservation of '---
native marine biota, shellfish propagation, and commerical-and sport
fishing), esthetic enjoyment and recreation. Unless otherwise -
specified, the following near-shore waters shall be -protected for-
navigation (seafaring vessels and small craft), in addition to -----
uses listed above. MqlAVqi Harbor (Palau), Tomil "Harbor- (Yap ),; ------
Tanapag Harbor (Saipan), Oror en Newacho Harbor ( Truk),-- Ponape ; '
Harbor (Ponape), and Majuro Harbor, immediately adjacent to -the
dock.- r (Refer to Figures A, B, C, D, E, and F respectively^} -"All ':'
other waters in, around, and adjacent to docks and piers_not "listed-
above ah«n be protected for qmali boats navigation ,:r ~ :~ ~'_ ~-~
, - ----_- To the extent that most of the lagoons in the district
centers are highly polluted, fishing, wading or swimming in waters --"
reserved for recreation and also known to be polluted shall "bepro- --
hibited until such time that they have been brought ^in'domplianie7"' -
.with quality standards. All possible efforts shaij: ^be "made- via --
news media and other means to inform the people of -the ^condition xif _
these waters. -~ ---- - .....
-------
11.3 Off-Shore Waters. In recognition of the multiple
uses (industrial water supply, propagation of fish and other aquatic
life and wildlife, esthetic enjoyment, recreation, and navigation)
made of off-shore waters, the risks of occasional ingestion by humans,
and need for protection to the maximum erfcent feasible for all uses,
the most stringent standards of those previously described shall
apply to these waters.
11.4 Waters for Other Purposes. For precautionary measures
against accidental ingestion of pathogens or chemicals attributed"""""".'
to sewage discharge, fishing or swimming within close proximity
of any sewage outfall inside a lagoon or inner reef is prohibited.

STATEMENT P.- POLICY
It snail bs the pus lie policy of Gu2.-a TO:
~'~
!. conserve, protect, raintain, and improve 7,19 quality
for or inking water susply anc food processing, for t.-.a c.-avth and
propagation of aquatic life, for marine research and for t.-.e
conservation of coral rests and wilserness areas, a~d for ccoestic,
agricultural, cstrcnercial , industrial, recreational and ot->er
lagitinate uses;
2. provide that no pollutant dischargs into any waters is allowed,
unless (a) the discharge first receives processing wnich will
assure the pollutant removal or provide the control technology
necessary to protect the legitimate beneficial uses of the waters,
and (b) the discharge meets the effluent limitations established for
that discharge; and
3. provide for the prevention, abatement and control of new and existing
water pol I ution.
Further, unser terms of U.S. Public Law 92-500, it is the national goal
that:
I. the discharge of pollutants Into navigable waters be eliminated by
1965;
2. wharavar attainable, an interim goal of water quality, wr.ich provides
for the protection and propagation of fish, shellfish and wildlife,
and provides for recreation in and on the water, be achieved by July
I, 1983; enc!
3. the discharge of toxic pollutants in toxic amounts be prohibited.
Therefore, pursuant to the authority contained in the Water Pollution Control
Act (Section 9950.5 Cb) and (e) of Chapter II, Title X of trie Govameant
Code of Guam), which authorized the formulation of standards of water purity
and classification of water according to the trast beneficial uses of such
waters, the Guam Environmental Prorsction Agency hereby proposes to adopt
the following standards of water quality for Guam.
»
Waters whose existing qualiry was betrer than the establishsd srandards, as
of April 1963, will oe maintained at the sane htgn qual i ty-.exisTir.s at -that
tiir.s.
Waters whose existing qual iry is less tnan the esrabl ished sTancarcs for
their use due to the presence of substances, conditions, or ca-bi.-.ations
thereof attributable to domestic, corrsrcial and industrial disc.iarg»s or
agricultural, construction and other land-use practices, shall be Irproved
to ccnply with the establisned standarcs. ; "
Waters will r.ot be lowered in quality unless sncJ until it has isen affirr.a-
tlvaly demonstrated to the Board of Directors of The Guam Envirc.-rental
Prorection Agercy tnat such a change is justff iasle as a rssul- of recassar\'
social, envi ronnsntal , or economic development and will not ir.Terfe-e wirn or
Decore injurious TO any usas /nade of, or potenrialiy possible, in such warers.
Any industrial, public or private project or ceveiossant, which '-ould const irjte
3 ne- or increassc sour-a of pollution, will require, as osrt of the iniTia!
project dasign, provision for the pollutant reroval or control technology
nacesssr- y to protect tne designatec use of recsivt.tc waters o- r.sir.tain tns
existing high cuB.'ity of the receiving waters.

CATEGORIES CF WATERS - The follow ing categories of waters ralate to
the different liquid components of tn» hysrslogic cycie. ;
A. Coastal Wafers
!. Category AA Waters
The uses to be protected in this category of waters are marine
research, propagation of aquatic life (particularly coral
reef organisms), conservation of wilderness areas, aesthetic
enjoyment, and such recreational activities as do not inpair
tha other estaolished uses. This category of waters shall
remain free from polluTion attricutaale to domestic, cccwercial,
and Industrial discharges or agricultural, construction and
other I and-use practices trat ir.pair their protected use. No
pollutant discharges wi11 oe permittee Therein. V/heraver
recreational facilities cu.-rs.it ly exist in these areas, such as
Tarague Seach, such uses ir.ay conrinue with their pol iuTant Impacts
control lee to prevent destruction of other water uses.
The categorization of any water area as Category AA shall not
preclude other uses of such waters compatible with these
objectives and In conforaance with the standards applicable
to them.
2. Category A Waters
The uses to be protected in this category of waters are recrea-
tion (including swimming, surfing, skin and SCUSA diving,
skiing, and other primary contact'sports), aesthetic snjoyr.er.t,
propagation of aquatic and associated wildlife, cccRercial,
Industrial, and navigational uses. It is the objective that
discharges of any pollutant be controlled to the degree
necessary to protect the waters for their specified uses.
B. Fresh Waters
I. Category I Waters are defined as all grouncwatsrs.
la. This suocategory Is the basal water lens and the perched
water systems. Sasal water lens refers to fresh ground-
water which is In hydraulic continuity with sea water en
which it floats; perched water systetns refer to fresh
groundwatsrs in aquifers whose inpsrr.sab!e lower
boundaries lie above sea level.
Zone la-1; Waters within this use-zone are those that
are currently used or potentially cevelopable as drinking
water resources. Waters within this zone shall be protected
for use as drinking watar.
Zone Ia-JT; '"'atars rfitnia tr.is jsa-ro.-.e ars Tr.cse i-hat
are proven to be r.ot potentially developable as a drinking
water resource. . Trese waTers (ray flow inno adjoining
coastal waters and acT as a buffer to prevent da.-rage to
inland arinking water resources by the intrusion of salt
water. Within this zone, treated waste may be discharged
if it is positively csmsnstrated That suca discharge will
not adversely affecT crour.swaters tnat are eiTher currently
or potentially ieveissaila for drinking water. Zone (s-H.
shall be defined as all crcu.-.a,vaters bar.aters descending vertically to
waters identified as ia waters. The use of these v,atsrs is
replenishment of la waters TO ensure The quality and quantity
of drinking nater resources necsssar'/ to supply tne current
and future neecs of tr.a pecs I e of Guam. Three use-zones
ars estaslishec witnin this suscatsgory.
27
-------
Zone !b-I (Conservation Zone). G.-ound'-aTars wiv'hin this
zone rapienish ia-l waters. They shal I os kapr fra* frcn
pollution. The watershed shall be raintainec as a
conservation area. No pollutanr discharges will ba permitted.
Lands within boundaries identified as It-J v.hic.1 are owned
by the Government of Guass snail be Kair.tsi.-.ad at tneir
current lane usa. Privately owned !a.ias shall is mai-tained
at tnair psraitred osnsiTies ar.d uses as of rr.e effective
date of these standards.
t
Zone Jb-n (Resource Zone). Groundwaters' witnin this zone
replenish la warars that are developable for drinking
watsr. Pollutant discr.arges, shall be treated to the degree
necessary TO prorect la waters for this uis.
Zone Ib-iiL(Hecharje Zone). GroundwaTers within this zone
replenish waters that are not economically developable for
drinking water use and are, therefore, catecoriied for
treared discnarga. Discharges within this zone shall be
treated to the extant necessary to protect la-H waters for
their categorized use.
2. Category 2 Waters are defined as alt surface fresh waters. Thare
are three suasategories.
2s. This subcatsgory is cocposad of waters that flew contin-jcusly
over the land surface in a defined chznnsi or bad, such as
streams a.-d rivers.
2t>. This suocategory is composed of standing waters in basins
such as lakes, rarshes, swairps, end ponds, either natural or
nan-siade.
Two use-zones ere established for 2s and 2s waters. '
Zones 2a-I and 2b-i: The uses for these zones are drinking
water resources, conservation of wilderness areas, and
propagation and preservation of aquatic life and aesthetic
enjoyment. It is the objective that these waTers shall
ta kept free of substances or conditions attributable to
domestic, commercial and industrial discharges, or agricultural,
construction or other land-use practicss that impair their
use. No pollutant discharges will be psrairted. A (nanageffient
progran shall be implemented for any watershed of waters
categorized as 2a-I or 2b-l.
Lands within boundaries i-dentified as 2s-I and 23! which -are
owned by the Government of Guarn shall be naintained at their
currant lar.d-asa. Privately o>isd lanes =fi;I 1 05 .Tiainrainad
at their ps.-nittad densities snd cses as OT the «rfa.=Tive
cat* of thes* stanoards.
Zones 2a-S and 2b-3: The uses for these zones are prirsary
body contact recreation, aesthetic enjoyrr3.it, protection
and propagation of aauatic life; co.--9rcia,r, agricultural,
and industrial watsr supply- Waste discharcss shall ba
controlled to the degree necessary to p.-ctscT tress uses.
2c. This sutcategory comprises all waters flowing over the land,
either as unconfinad sheet ru.-off, or as runoff confined to
channels witn ints.-r.irtsnt flew. Tr.sse warers shall ta
kept frea from poll-tior. associated with r.iiT.an iar.d-use
activities to tha extent that tha cJesicnatsd uses of waters
receiving 2c waters ars not impaired.
3. Crir.kir.g Weter
All public and dcmesTic water supplies used for husan consurotion,
either directly or indirectly Through focd or bavaraca processing,
are categorized as "Drinking Warsr." These warers shaiI be Treated
as necessary to provide watar of good quality for cc.TSjr^ticn by the
people of Gu2.T. Specific standards asolicasia Ta ^-;-^;«^ ,.-*~^*-

C. Estuaries
Esruarfes are defined as zones of interaction between near-snore
waters and rivers wirhin w.iicn tidal action and river flew bring
about mixing of fresh and salt water.
s
The waters of Estuaries are prcrectea for propagation of aquatic
and assocfarad wildlife, agriculture, csr.-3.-c i a r ana industrial
water supply and recreation.
During periods of nonral river flow, estuaries are usually
characterized by stratified csndiTisns and to* velocity prsfilas
with resultant limited mixing cnaracreristies snd extenced
flushing tines. Estuary waters, therefore, are highly sensitive
to dsgrac'arion by poMutants. Discharges of any pollutanrs
incampatiole with tna above cesigr.ated uses sfis!! not ss permitted
in Esmaries.
H. WATER QUALITY CRITERIA -
A. General Criteria Applicable to all Territorial Watars.

C. Pollurant discharges shall be controlled so as to protect not only
the waters receiving the discharge directly, but also these waters
into which the initial receiving waters may flow.
0. Whenever the natural conditions are of a lower c/Jality t.-.ar. the
criteria assigned, the narura! conditions shall constitute the
water quality criteria.
V. EFFLUENT LIMITATIONS
A. General Criteria
Effluent shall be fully and homogeneously dispersed and nixed insofar
as practical with receiving waters. Use of 8 I imiTed rr.ixing zone
nay be permitted on receipt of satisfactory evlcance t^.at such a
zone is necessary and will not adversely affect the designated uses
of the receiving waters.
Consideration will be given to reasonable dispersion tir.e and distance
to allow mixing of affluent ani receiving waters. Such cisTence shall
be defined and controlled as required by the Asjr.inistnror. Wherever
nixing zones are allowed, zones of passage, i.e., ss.trinuous water
routes of the volume, area and quality necessary to allow passage of
free-swimning and drifting organises with no significant effects
producsd on tt;siripopulations, snail bs provided.
The Agency reserves the right to amend or extend the fo! lowing criteria
as improved standard methods are developed or revisions consistent
with the enhancement of water quality are
I. All sewage shall receive at least complete secondary treatment as
provided by conventional treatment processes before discharge
to waters of the Territory. Industrial wats.-s and or.-.sr wastes
shall receive treatment or corrective action equivalent to that
received by ccnplsre seccncary sswags treatment. Nsrwithstanding
the abovs, a higher degres of tresrment r.ay te rerjired as
oeterrr.ined by rhe Agency ro eliminate or prave.rr pollution of
waters of the Territory.
2. Dilution of the effluent frc.ii any westewater so^rc= is not
acceptable as a method of treatment of wastes in orcar to r.eet the
standaras ser forth in rnis Section. Rstner, ir snail be 7,13
obligation of any person discharging pollutanrs of sr,y kind TO trie-
v.aters of the Terrtrory to provide -me bast ;ol!uT3.ir removal or

ableness, and sound engineering judgement. In raking determina-
_- tions as to what degre* of treatmsnT is the best pollutant
reiroval or control within tne meaning of this paragraph, any
person shall consider the following:
a) ths degree of wasre reduction that can be achieved by
process Changs, improved houseXaepira, and recovery
of incividual waste componenrs for rauss; and
b) whether individual proesss wastawatsr streams should bs
segregated or combinee.
3. Measurement of pollutant concentrations to determine compliance
with the effluent limiTarions s.-all be cade by tne discharger
at the point immediately following the final treatment process
and before mixing with other waters. Points of msasuranent
shall be designated by the Acsncy in an individual permit,
after consideration of the elsrsnrs contained In this section.
If necessary, the concentrations so measured shall oe recomputed
to exclude the effect of any dilution that is improper under
this standard.
4. Every person discharging effluent to the watsrs of the Territory
shalI submit operating reports to tne Agency ar a frequency
to be determined by the Agency. Such reporrs shall contain
information regarding the quantity of effluent discharged, and
the concentrations of those physical, chemical, bacteriological
and radiological parameters which shall be specified by'the
Agency; and any additional information the Agency ray reasonably
require,
5. In addition to other requirements no effluent shall, aione, or
in combination with other sources', causa a violation of any
applicable Water Quality Standard. When the Agency finds that
a discharge that would ccsply with effluent limitations contained
in Section V.A.I, would causa or is causing a violation of
Water Quality Standards, the Administrator shall take appropriate
sctlon under Section 570*3 of the Water Pollution Control Act
to require the discharge to msef whatever effluent limits are
necessary to ensure ccmpliance with the Water Quality Standards.
When such a violation is caused by the cumulative effect of more
than one source, several sources may be joined in a schedule
of compliance. Measures necessary for effluent reductions
will tw determined on tne basis of technical feasibility, economic
reasonableness, and fairness to ail dischargers.
3. Mixing Zones in Receiving Waters
The water quality criteria in Section U shall apply within a
mixing zone unless specific sltarr.sta criteria ire apcrovsd by tne
Administrator for specified parameters. Tne mixing zone shall be
defined by specified 1 ir.ear distance, volume or area, discharge
location, maximum fiow, and maximum concentrations of important
constituents which are determined on a caseby-case basis using the
fol lo-'lrg criteria: :"
II. Mixing zones shall b« as small as practicable and shall r.ot be
of such sire or shape as -= cause cr confributs to the impairment

or shore!ina configuration, ths mixing velocities, anc other
hydro logic and orv/aiccrar-nic cr.arzcTerisTics;
b) present and anticipsrad future use of the body of water;
-------
c) present and anticipated future qualiTy of 77:9 oooy of
water; and
d) the ratio of the maximum flow rats of waste :airg discharged
to Trie lowest recorded flow rats of the receiving WS
2. An sdecuara rone of passage shall exist a- at! tises for tne move-
ment or drift of aquatic I ife.
3. Where two or more nixing zones ara in cicse prcxi-s.'Ty, They shall
be so defined that a continuous zone of passage for aquatic life
is ava i I sale.
>
4. Mixing zones shall not intersect any area of a-y vaT8"s in such
a rannar that the maintenance of aquatic life ir. Tne body of
water as a wnole *ould oe adversely affecTai.
5. The discharge shall not violate the basic standards applicable
to a 1 1 waters nor shall it unreasonably inter- fare with any
actual or probable use of the waters witnir TT.S cixing zon«,
C. Prohibited Discharges
No parson shal I cause or permit:
I. the discharge of any wasTes or wastewaters regardless of volu«»,
unless authorized by tne Ad.Tiinistrator under Sacrion 57045 of the
Water Pol lution Control Act or unless subject to control or
modification required by a schedule of compliance established
by the GE?A 2oard of Directors;

content at saturation, in accordance with Figure
4-1.
A review of recent studies of dissolved oxygen
concentrations in San Francisco Say-'3'' indi-
cates that the average concentration in portions
of the Say not s,gnifi'cant!y affected by man's
activitias acorcximat^s 35 c^rcent or the sa'ura-
tion concentration. This value appears relatively
constant throughout the Say system with minor
variations; for example; day time concentrations
in the 3'ea upstream of Carquinez Strait are
usually h inner than 35 percent due to aicai
activity. Applyng 35 percent of the saturation
concentration together with the above require-
ments for a minimum dissolved oxygen concen-
tration of not :ess than 5.3 m.g/!, results in
maintenance- . in applica-
tion t ^ m o e r a t u r ° ^nd cnioride concent ration a r a
determined at the location where the dissolveo
oxygen sample is obtained. These .measurements
permit determination of the saturation concen-
trations.
The disscived oxygen objective departs from, tp.e
interim 3!an statement for fresh waters and
enclosed bays in wording but not in philosophy;
the above wording is more closely tied to the
natural habitat recognizing the resilience inherent
in estabi shed aquatic life populations and tne
need for more str.ct control as natural oxygen
values accroach min'mum values for aquatic -ife
sustenance and crcpagaticn. The specific case of
the California Ocean Plan :s also relevant here, :or
this plan spec:f:es that d'ssoived oxygen shall not
be dsoressed icr0 "han 1C o^rcenc from ~r^r
which occurs naturaiiv. Thus the conceot ern-
cod'ed in the 3CjSCt:ve is consistent with the

4. Regional 3oards may, in accordance with Section 31o(a) of
the Federal Water Pollution Control Act of 1972, and
subsequent federal regulations including 40 CFR 122, grant
ah exception to Specific Water Quality Objectives in this
Plan. Prior to becoming effective, such exceptions and
alternative less stringent requirements must receive the
concurrence of the State Board.
5. Natural wa.er temperature will be compared with waste
discharge temperature by near-simultaneous measurements
accurate to within 1°F. In lieu of near-simultaneous
measurements, measurements may be mace under calculated
conditions of constant waste discharge and receivinc water

The State 'Water Resources Control Board and the California
Regional Water Quality Control Boards will administer this |
plan by establishing waste discharge requirements for dis-
charcres of elevated temperature wastes.
I
2- This plan is effective as of the date of adoption by the
State Water Resources Control Board and the sections
pertaining to temperature control in each of the policies |
and plans for the individual interstate and coastal waters
shall be void and superseded by ail applicable provisions
of this plan. |
3. Existing and future dischargers of thermal waste shall
conduct a study to define the effect of the discharge on
beneficial uses and, for existing discharces/ determine
I
design and operating changes which would be necessary to
achieve compliance with 'the provisions of this olan.
Waste discharge requirements ror existing elevated tamtjera-
ture wastes shall be reviewed to determine the need for I
studies of the effect of the discharge, on beneficial uses,
changes in monitoring programs and revision of waste .
discharge requirements. - I
Ail waste discharge requirements shall include a time
schedule which assures compliance with water quality ' I
objectives by July 1, 1977, unless the discharger can
demonstrate that a longer time schedule is required to
complete construction of necessary facilities; or, in I
accordance with any time schedule contained in guidelines
promulgated pursuant to Section 304ib) of the Federal
Water Pollution Control Act. ' I
5. Proposed dischargers of elevated temperature wastes may be
required by the Regional Board, to submit such studies orior
to the establishment of waste discharge requirements. 'The
Regional Board shall include in its recruiremants appropriate
post-discharge studies by the discharger.
7. The scops of any necessary studies shall be as outlined bv
the Regional Board and shall be designed to include the
following as applicable to an individual discharge:
A. Existing conditions in the acuatic environment.
3. Effects of the existing discharge on beneficial uses.
C. Predicted conditions in the aquatic environment w_-.-i
waste discharge facilities designed and operated in
compliance with the provisions of this oian.

order to deterraine compliance with effluent or receiving
water temperature (or heat) retirements.
Furtherore, for- significant thermal discharges as
determined by the Regional Board or State, Regional
3cards shall recruire expanded ccnitoring programs, to
be carried out either on a continuous or periodic basis,
designed to assess whether the source continues to crovide
adequate protection to beneficial uses (including the
protection and propagation of a balanced indigenous
com_TvUnity of fish, shellfish, and wildlife, in and on
the body of water into which the discharge is mace).
When periodic expanded monitoring programs are specified,
the frequency of the program shall reflect the probable
impact of the discharge.
9, The State Board or Regional Board may recruire a discharger ( s )
to pay a public agency or other appropriate person an amount

A.I The discharger has previously failed
out monitoring programs in a manner satisfactory
to the State Board or Regional Board, or;
3. More than a single facility, under separate
"ownerships, may significantly affect the thermal
characteristics of the body of water, and the
owners of such facilities are unable to reach
agreement on a cooperative program within a
reasonable time oeriod specified bv the State
Board or Regional Board.

department: shall adhere ~^> -he following procedure:
(1) if wa-ers have more than one classifica-
tion, -he rncsc serin gent wa-ter quality criterion of
all the classifications shall apply; and
(2) if a tributary water either receives a
sewage waste discharge or industrial 'waste discharge,
or has a lower classification than the confluence
water, and ihe tributary water affeczs the cualicy of
the confluence water, che rnosc stringer.- wa~er cuali-y

wii" be dece^~ined. The mixinc zone will be li-mited
to a volume of the receiving wacer that will
(A) not interfere with biological
corrraunitias or populations of important: species
to a degree which is damaging to the ecosystem, and

establish wacar quality standards for'surface waters of the
State of Washington pursuant to the provisions of chao-er
SO,48 RCW and the policies and purposes thereof.
AMENDATORY SECTION
WAC 173-201-020 WATER USE AND QUALITY CRITERIA. The water'
use and qualify criteria set forth in WAC 173-201-035 through
173-201-050 are established in concordance with present and
potential water uses of said sur^a.c_a waters and in considera-
tion of the natural water quality potential and limi-a-ions
of the sane. Nonetheless, the dynamic nature of ~he orocesa
is also recognized. Hence, frecuent review of ~hese uses
and criteria is anticipated; and revisions will be under-
taken as additional informa~ion is developed.
