                     rationale  they state: "Nutrients	The research
                     to  date  had not been  able to develop satisfactory
                     criteria for nutrient levels in open sea water that will
                     not over-stimulate  plankton production.  Thus, a  standard
                     for nutrients is omitted until a basis for such can be
                     found."

 that will cause deleterious or abnormal growths to
 occur on the substrate or to foster biotic growths
 that are harmful to beneficial uses."

-There are no specific criteria for any of the nutrients.
 The narrative statement concerning toxic materials might
 restrict phosphate at levels where damage to aquatic
 life occurred.   This statement is  as follows:   "Toxic
 material:  Free from biocides, toxic or other deleterious
 substances attributable to municipal,  domestic, or
 industrial wastes, or other controllable sources in
 levels,  concentrations or combinations sufficient to
 be harmful to aquatic life."

-The narrative statements concerning taste and odor and
 chemical constituents are the only standards that could
 apply to phosphates.   "Taste and Odor:"  For water
 supply:   "None  other than of natural origin."  Class B
 and C waters:   "None in such concentrations that would
 impair any usuages specifically assigned to this Class
 nor cause taste and odor in edible fish."  Class D:
 "None in such concentrations that  would impair any usages
 specifically assigned to this class."   For coastal and
 Marine waters:   Class A:   "None allowable."

 Class SB,SC, SD:   "None in such concentration that
 would impair any usages specifically assigned to this
 Class and none  that would cause taste  and odor in edible
 fish or  shellfish."

 Chemical constituents (freshwater):  Class A,B,C,  and D.
 'Voters  shall be  free from cheraical  constituents in  con-
 centrations  or  combinations which  would be harmful to
 human, animal,  or aquatic life for the appropriate,  most

 Chemical constituents (coastal and marine):  Class SA:
 "None in concentrations or  combinations  which  would  be
 harmful  to human,  animal,  or  aquatic life or which would
 make the waters unsafe  or unsuitable for fish  or shell-

-The following declaration of policy in 6301, Chapter 63,
 Title 7, Part VII, Delaware Code is:
 "(a) It is declared to be the public policy of the State
 to maintain within its jurisdiction a reasonable quality
 of water consistent with public health and public enjoy-
 ment thereof, the propagation and protection of fish and
 wild life, including birds, mammals, and other terr«-
 estrial and aquatic life, and the industrial development
 of the State.
  (b) It is the purpose of this chapter to safeguard the
 quality of state waters againist pollution by (1) pre-
 venting new pollution in such waters and (2) controlling
 any existing pollution."

 The adopted standards approved by the Secretary with
 certain exceptions and recommendations that could apply
 to phosphates are those concerned with toxic substances
 and taste, odor and color causing substances:  "Toxic
 Substances:   None in concentrations harmful
 (synergistically or otherwise) to humans, fish, shell-
 fish, wildlife and aquatic life.  Taste, Odor and Color
 Causing Substances:  None in concentrations which cause
 tastes, odors, colors, or impart tastes to fish and othei
 aquatic life."

-There are no specific criteria for nutrients such as
 phosphate and no narrative statement directly applicable
 to nutrients such as phosphate.  The only item in the
 water quality standards of Florida, as approved, that
 might be used to protect that States waters from ex<-
 cessive amounts of phosphates and there accompanying
 problems would be the anti-degradation statement.

-There are no specific criteria for nutrients such as
 phosphate, nor is there a narrative statement directly
 concerned with phosphate or other nutrients.

 The following revision of water quality standards
 regarding nutrients was submitted in a letter dated
 December 26, 1967 prior to approval by the Secretary
 from Walter B. Quisenberry, M.I), to Mr  William B.
 Schroeder; "Insert the following section immediately
 preceding the section titled "Wastes from \essels and
 Marinas:"

"Control of Nutrients"

       "Nutrient discharges were pointed out in testimony
 as being a potential problem in several water areas such
 as Kaneohe Bay and Pearl Harbor.  The agency is cognizant
 of this potential problem and nutrient limits have been
 included in the water quality criteria.  At present the
 Agency knows of no practicable methods for the control
 measures when the means to do so become available."

 Hawaii has never adopted and submitted for approval an
 antidegradation statement that also could be used for the
 protection of its high quality waters from problems due
 to excessive nutrients such as phosphates.

-Under the section titled "GENERAL WATER QUALITY STANDARDS
 FOR INTERSTATE STREAMS" is the narrative statement	
 Interstate waters shall not contain:.....Excess nutrients
 of other than natural origin that cause visible slime
 growths or other nuisance aquatic growths.

 There is no specific criteria for nutrients such as
 phosphates and Idaho does not have an approved anti-
 degradation statemtnt to protect existing high quality
 waters from excessive amounts of nutrients such as
 phosphate.

-The water quality standards for the Interstate Waters,
 Wabash River and Tributary Streams Crossing into Indiana,
 Interstate Waters Mississippi River Between Illinois and
 Missouri, Interstate Waters Ohio River and Saline River,
 and the Interstate Waters Mississippi River Common
 Boundary Between Illinois and Iowa do not include
 specific criteria or a narrative statement directly
 concerned with limits for phosphates and other nutrients.
 Specific criteria for phosphate concentrations was
 included in the water quality standards for the following
 interstate waters:

                        PHOSPHATE CRITERIA -  10

Indiana             -There are no specific criteria or  narrative statement
                     limiting phosphate or other nutrient  substances  in  the
                     Indiana water quality standards for any of the inter-
                     state basins other than  the Lake Michigan drainages,
                     unless the antidegradation statement  could be applied
                     for existing high quality waters.

                     Indiana recently revised Official  Regulation SPCIR-1
                     and issued SPCIR-2 which limits the amount of phosphate
                     discharge into the Lake  Michigan and  Lake Erie basins.
                     The limitation is as  follows:
                       1 'Phosphorus Removal In Great Lakes  Tributary Basins :
                        The following municipalities will  be required to pro-
                        vide at least 80 percent reduction of total phosphorus
                        on or before the end  of 1972:

         Single Daily Value or Average - not more than '
         0.04.

-The following narrative statement could, in my opinion,
 be used to limit the amount of phosphate and other
 nutrients in the aquatic environment:

    1. Public Water Supply

       All substances detrimental to treatment processes
       shall be limited to non-detrimental concentrations
       in the surface water.

    2. Aquatic Life

       All substances detrimental to aquatic life shall
       be limited to non-detrimental concentrations in
       the surface waters.

-The only standards regarding the limiting of phosphates
 in the aquatic environment are as follows:

    1. Antidegradation statement - Existirjg high quality
       waters could be protected from damages resulting
       from the discharge of effluent containing high
       phosphate concentrations to the aquatic environ-
       ment .

    2. The general criteria assigned to all  of Kansas
       Interstate Basins  -  "Pollutional substances will be
       maintained below maximum permissible  concentrations
       which would be detrimental for public water supplies
       recreation requirements detrimental for public
       water  supplies,  recreation requirements,  ....and
       other  established  beneficial uses."

-All interstate waters  of Louisiana are assigned a general
criteria which could be  used  to protect  such waters  from
excessive concentrations of phosphates or other nutrients.
This  statement with  slight  variations of  use classifica-
tions is:

       Wastes  after discharge	shall not  create condi-
       tions which will adversely affect public  health or
       use  of  the  water for  the  following  purposes:   domes-
       tic  or  industrial water supply,  propagation of aqua-
       tic  life,  agricultural  water,  recreation,  and  other
       legitimate  uses.
