INTRODUCTION

This  digest  is  compiled to provide general information to the public as well
as  to  Federal,  State,  and  local  officials.  It contains excerpts from the
individual   Federal-State   water  quality  standards  establishing  pollutant
specific  criteria  for interstate surface waters.  The water quality standards
program  is  implemented  by  the  U.  S. Environmental Protection Agency where
responsibility   for   providing   water   quality  recommendations,  approving
State-adopted  standards  for  interstate  waters,  evaluating adherence to the
standards,  and  overseeing  enforcement  of  standards  compliance,  has  been
mandated by Congress.

Standards,  a nationwide strategy for surface water quality management, contain
three  major  elements:  the use (recreation, drinking water, fish and wildlife
propagation,  industrial,  or  agricultural) to be made of the navigable water;
criteria  to  protect  these  uses; and an antidegradation statement to protect
existing high quality waters, from degradation by the addition of pollutants.
Guidance  for the development of standards by individual States is contained in
two  EPA documents entitled Water Quality Standards Handbook (1983) and Quality
Criteria for Water (1986).

Iron  is  an essential trace element required by both plants and animals.  Iron
containing  waters  usually  result  from mine drainage and discharges from the
production  of  steel.    In low concentrations iron does not exhibit any toxic
effect  on  aquatic organisms.  However, when in sufficient concentration, iron
will  produce a gel or floe, which is detrimental to fish and aquatic habitats.
Iron,  is  also  known  to affect the taste of water and stain laundered clothes
and plumbing fixtures.

The 1986 Quality Criteria for Water recommends the following:
                                               •»     •»
    0.3 mg/1 for domestic water supplies (welfare)

    1.0 mg/1 for freshwater aquatic life

Since  water  quality  standards  are  revised  from  time  to  time, following
procedures  set forth in the Clean Water Act, individual entries in this digest
may  be  superseded.    This digest will be updated periodically.  Because this
publication  is  intended  for use only as a general information reference, the
reader  needs  to  refer  to  the  current  approved water quality standards to
obtain  the latest information for special purposes and applications. These can
be  obtained  from . the  State  water  pollution  control  agencies  or the EPA
Regional Offices.

General  criteria:    All surface waters shall be free,
at  all  times,  from the harmful effects of substances
that   originate   from  artificial  sources  and  that
produce   any   public   health   hazards  or  nuisance
conditions,   or  impairment  of  uses.    The  harmful
effects   may   result  from  any  concentration  of  a
substance  that  causes  toxic  effects,  alone  or  in
combination    with   other   artificial   or   natural
substances.    Such  substances  shall  be  limited  to
concentrations  in the receiving water that will not be
harmful to human, animal, or plant life.

Toxic substances narrative:
(ii) The  waters  of  the state shall not be toxic as a
result  of  the  effects of substances originating from
artificial  sources,  whether  alone  or in combination
with other artificial or natural substances.

terms  of  toxic  levels  in  fish, published in "Water
Quality  Criteria"  (National  Academy  of Engineering,
1973),  which  is hereby adopted by reference, shall be
used   as  guidelines  in  assessing  toxicity .due  to
bibaccumulation.

(iv)  When  criteria for single compounds have not been
published  or  are incomplete, or when complex mixtures
can   result  in  interactions  among  substances,  the
department   shall   utilize   laboratory   and   field
bioassessment   methods  and  procedures  to  establish
site-specific water quality criteria.

Any   concentration  of  a  substance  from  artificial
sources  that,  alone  or  in  combination  with  other
artificial  or natural substances, causes toxic effects
on    humans    shall   be   limited   to   non-harmful
concentrations.

Substances     that     can    bioaccumulate    through
bioconcentration  or  biomagnification  to toxic levels
in  aquatic life, semiaquatic life or wildlife consumed
by  humans  shall  be  limited  in  surface  waters  to

water,   (either   alone   or   in   combination,  when
affirmatively  demonstrated  to be non-bioaccumulative)
when  not  specified  elsewhere  in this Section, shall
not  exceed the concentration specified by the fraction
of  the  96-hour  LC50 value which predicts a no effect
chronic  level (as determined by the use of established
acute/chronic  ratios).  If an acceptable acute/chronic
ratio  is  not  available,  then  that  toxic substance
shall  not  exceed  one-one  hundredth  (0.01)  of  the
96-hour  LC50  or  if  it is affirmatively demonstrated
that  a toxic substance has a half-life of less than 96
hours   or   is   not   bioaccumulative,   the  maximum
concentration  shall not exceed one-twentieth (0.05) of
the  96-hour LC50.  If it is affirmatively demonstrated
that  the  standard for a particular toxic substance as
specified  in  Rule  .0211  or .0212 of this Section is

the director.

Action  Levels for toxic substances [Rule .0211(b)(4) ]:
If  the  levels of any of the substances listed in this
Paragraph  (which are generally not bioaccumulative and
have  variable  toxicity  to  aquatic  life  because of
chemical   form,   solubility,  stream  characteristics
and/or    associated    waste    characteristics)   are
determined  by the waste load allocation to be exceeded
in   a   receiving  water  by  a  discharge  under  the
specified  low  flow  criterion  for  toxic  substances
(Rule  .0206),  the  discharger  will  be  required  to
monitor  the  chemical and/or biological effects of the
discharge  as  part  of the NPDES permit; efforts shall
be  made  by  all  dischargers  to  reduce or eliminate
these  substances from their effluents; after receiving
such  monitoring data for discharge, the substance will
be  limited to the level listed in this Paragraph or an
appropriate  toxicity  limit  will be set as determined
using the requirements of Rule .0208(a).

                        demonstrated  to  the Board that a higher concentration
                        has  no  adverse  effect,  chronic  or  acute,  on  the
                        intended uses of the water body in question.

                        General  considerations:    (1)  All  methods of sample
                        collection,   preservation,   and   analysis   used  to
                        determine  compliance  with these standards shall be in
                        accordance  with those specified in the current edition
                        of Standard Methods for the Examination of Water and
                        Vastewater  or  methods  specified by the EPA in 40 CFR
                        Part 136, as appropriate.
                          Samples  should  be  collected at approximately equal
                        intervals   and   under   those   conditions  of  tide,
                        rainfall,  and  time  of  day  when  pollution  is most
                        likely to be a maximum.

                          (2)  Whenever  natural  conditions  are  of  a  lower
                        quality  than  an  assigned water quality criteria,  the
                        natural  conditions  shall constitute the water quality
                        criteria.

                          (3)  Whenever 2 numeric criteria are in conflict,  the
                        more  stringent  criteria  shall  constitute   the water
                        quality criteria.

                          (4)  Pollutant discharges to either surface or ground
                        waters  shall  be  controlled so as to protect not only
