  It  is the policy of the Environiental flanagement Commission to lain tain,  protect,  and  enhance mater quality

  approve any project or development   nhich  would result in the significant degradation  of  waters whose existing
  quality is better than the assigned  nater  quality standards, unless such degradation  is  found by  the coimiss-
  ion  to be justifiaBle to provide necessary economic ind social development.  In  such  cases,  those pollution  r
  control leasures necessary to  aaintain  high iater quality"nil be required  where  physically and  economically
  feasible.  Prior to approval of; my  project or deveiopient which nil result in  the significant degradation of
  »ater quality, the commission  nil  solicit, through public notice or public hearing or both, comments from the ,
  public and intergovernmental agencies  relative to.the project or development  and  anticipated water quality
  degradation.   In"cases.where  the project  or development,  requires a HPDES penit,  the Environmental Hanagement
  'Commission shall publish in conjunction nth the public notices required by 15 HCAC 2H .0109U)  (regarding
  application for NPDES penit]  and 15 NCAC.2H .0109(b)  (regarding a public hearing  on MPDE3 .perilt application)

  iore,  the  commission shall considsr the present  wd inticioated usage of said wter, including  any. uses  not   •
  specified  by  the assigned  classification   (such  as outstanding national resource wters or  »aters.of exceot-
   ional-Mter. quality)'and  nil not'allo» degradation'of  hign  quality  «aters  belon the »ater-.quality-necessary
   to isintain existing  and  anticioatefl uses.  In uoleienting  this policy,  the comssion nil keep the United
   States  tnvironiental  Protection Agency informed  and »ill  provide it  nth such inforiatioh as it nil  need in
   discharging  its  responsibility under  the Clean Hater Act,  33 U.S.C. 466 et. seq.

   ~he'concentration  of  toxic  substances  in  the receiving *ater,  (either, alone or in combination, »nen  aff.in-
   atively demonstrated  to be  non-bioaccumulative)  »hen  not  specified elswhere in this  Section, shall not  exceed
   the concentration  specified by  the  fraction of the 96-hour LC50  value  »hich 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 LCSO or if it  is
    affirmatively demonstrated  that a toxic substance has a half-life  of less  than  96  hours  or  is not bioaccumu-
  .lative, the maximum concentration shall.not exceed one-txentieth (0.05]  of the  96-hour LCSO.  If it is
    affirmatively demonstrated  that the standard  for a particular toxic substance   as  specified in Rule .0211 or
    .0212 of this Section'is inappropriate  for a  specific stream segment,  the commission  lay revise  the applicable
    standard on a case-by-case  basis in accordance nth the provisions of  Section  143-T214.1  of  the Seneral
    Statutes of North Carolina.           ..                           ,        • •'•  •

State   Narrative  Language  Pars   Low   Flow
  The  governing  flow criterion for water quality standards except toxic substances,  generally shall  be the
  unnui average flow for a period of seven consecutive days tint has an average recurrence of once in
  10 years (7810).
  These governing criteria are  established  specifically for setting effluent  Imitations jnd for the design of
 mstiwater treatient facilities.   In addition,  the governing flow  also  establishes a  value below whicn
 deviations froi water quality standards can be anticipated.

State   Narrative   Language   For:   Mixing   Zones
 A imng zone lay  be established  in  the area  of i discharge  in  order to provide reasonable opportunity  for tne
 nxture af the  wastewater  with  the receiving  waters.   The liiits of such lixing zones  will  be defined by  the
 division on a case-by-case basis  after consideration  of  the  lagnitude and  character of  the  waste discharge and
 the size and character  of  the receiving waters.   Such  rones  shall  not:
 (1)  Prevent free  passage  of fish  around  or  cause fish  mortality  within the  mixing zone,
 {21  Result in  offensive conditions,                                                               ...
 (3)  Produce undesirable aouatic  life  or  result  in  i  dowinance  of  nuisance species outside  of  the  assigned
 nxing zone.                                            ->                               .

 IB addition,  a  imng zone shall  not  be assigned  for  fecal coliform organises   in  waters classified  'ft-lt1,
