        The following list of compounds are recommended for  use  in defining
        Appendix A of the Consent Decree.  In compiling this list every
        attempt has been made to compile v/ith the spirit and language of
        the Consent Decree, while providing the necessary specificity
        required in a scientific program.  The recommended list  of Priority
        Pollutants contains the following:

              1.   Every specific compound called for in the agreement
                   is present and marked with an asterisk.

              2.   The list contains all those compounds which were
                   specifically named or referred to in describing a
                   group or class of compounds.

              3.   The ambiquous compounds or classes ]of compounds
                   which were named in the agreement are- included in the  '
                   list.  The non-specific groups or. classes are under-   .
                   lined.  Below, each group or class is a recommended
                   specific compounds representative of the  group.  In
                   selecting the specific compounds the following
                   rational and considerations were used.

                  . (a)  The frequency of occurance of the compound
                        in water.  In. order to make this evaluation
                        the reference ("Frequency of Organic Compounds
                        Identified in Water" by Shackelford  and  Keith)
                        was used.  This compilation is  incomplete;
                        reports of compounds found during some monitoring
                        operations were purposely deleted because they would
                        have' biased the data, e.g., data on  pesticides  -
                        and PCB's is particularly incomplete. On the other
                        hand, the compilation is biased toward compounds
                        of recent concern in drinking water, such as the
                        halomethanes; there was no practical way to remove
                        this bias.  There is also a geographic bias resulting
                        from differences in magnitudes  of monitoring activities;
                        e.g., the southeastern U.S. in disproportionately
                        represented.  Nevertheless, this data base is currently
                        the most comprehensive list of organic chemicals  that

TO:     Robert B. Schaffer, Director
        Effluent Guidelines Division
        In the settlement of several cases in the District  Court for the
        District of Columbia, the Environmental  Protection  Agency has
        agreed to review and revise regulations  based on  the  Best
        Available Technology Economically Achievable (BAT), New Source
        Performance Standards, and Pretreatroent  Standards for 21
        industrial categories.

        In this revision, consideration is to be given to the application
        of limitations of a list of 65 chemicals and chemical classes
        appearing in Appendix A'of the Settlement Agreement with the
        National Resources Defense Council (NRDC).  In order  to enable
        the Division to conduct a scientific study of industrial
        discharges, the various parameters in Appendix A  were further
        defined.  Without this information as a  point.Oif  reference, the
        analytical portion of the BAT review would be unmanagable given
        the limited time schedules and resources of the Agency.  This
        package contains background documents illustrating  the rationale
        of a working list of nonambiguous compounds which are derived
        from Appendix A.  These materials are generally referred to as
        priority pollutants.  The priority pollutants are specific
        compounds.  The Agency has established this unambiguous list of
        129 compounds  (including those specific  compounds named in the
        consent decree), which it believes fulfills the requirements of
        the court order and can be analytically  determined.  Moreover,
        these memoranda reflect the comments and suggestions  made by an
        Advisory Committee of NRDC (as well as EPA's concerns).

        Documents included in this package are:  A Rationale for
        Recommended List of Priority Pollutants, November 19, 1976, with-
        list of 123 priority pollutants; Revised List of  Priority
        Pollutants, April 26, 1977 (the green list) and Selection of
        Rationale (the blue list).  Also included is a memorandum titled,
        "Defining Asbestos for the BAT Review".   This paper recommends a
        definition of asbestos in effluents for  the express purpose of
        conducting Effluent Guidelines' BAT technical studies.

          of 1296 different organic compounds.  The compilation
         .represents 1S9 different geographic locations or
          literature references.  All the compounds except
          those specifically designated in the Consent Decree  -
          which are marked with an asterisk have been reported
          with a frequency of 5% or more of the total number
          of listings for that class of compounds.

     (b)  The availability of chemical standards for purpose or
          qucntitiations was considered a requiremer.t for
          inclusion on the list.  Therefore, every specific
          compound shown there is at least one vendor who
          can available to supply a chemical standard.

     (e)  In selection of the specific compound consideration
          was given so each subclass or group of compounds v/as

4.   In addition the following general assumptions were made  '
     in compiling the list:

     (a)  Polynuclear aromatic hydrocarbons are traditionally
          considered unsubstituted compounds.  Therefore,
          alkylnaphthaler.es and alkylbiphenyls were omitted
          from this section.

     (b). Chlorobiphenyls were also emitted because they would
          come under the PCS classification.

     (•c)  Heterocyclic polynuclear aroma tics  (e.g., dibenzofursn)
          were also omitted from consideration because PAH's
          traditionally contain only carbon and hydrogen.

     (d)  Phenol for the purposes of clearity are those compounds
          which are measured bly the 4-aminoantipyrine method.

        Energy and  Mining  Branch     >                                     /J"

TO-.     Robert B. Schaffer,  Director
        Effluent  Guidelines  Division
        With  the  onset of the BAT Toxic  Review, a list of recommended
        nonambiguous compounds (called priority pollutants) was developed.
        The purpose o* this list was  to  define the various parameters and
        compounds of concern in order to carry out a scientific study.  This
        list  was  then submitted to representatives of the Advisory Committee
        of NRDC for their comment and their suggestions.  Upon review by the
        Agency of comments and questions received from NRDC the following memo
        was writte-n to reflect Agency thinking on specific points of interest-
        Also  enclosed is a revised list  of priority pollutants which reflects
        changes resulting from NRDC's comments.  It was explained to NRDC at
        the time  of our meeting that  the recommended' list of priority
        pollutants was certainly not  the total known chemical world and that
        it was simply being used as a frame of reference for the purpose of
        the present BAT review.  The  list was prepared with this thought in
        mind  and  with the additional  consideration that the Agency intends to
        save, for further study, the  spectral tapes which will result from the
        screening analysis, together  with the extracts from the various
        samples.   Realizing that we have the opportunity to go back and
        reevaluate some of the earlier decisions made, comments received from
        NRDC  were considered in this  light.

        We would  like to now address  the specific points raised by NRDC in our
        meeting and answer them individually.

        1.  Comments presented under  the heading Chlorinated Benzenes.

            There, were some questions raised with regard to the absence of
            1,2,3,- and 1,3,5-trichlorobenzene from the list of compounds for
            direct consideration.  Both  of the compounds in question did not
            meet  the general criteria that was set down for consideration'in
            developing the list.  Both the frequency of occurance and
            reporting in the environment were far less than five percent of
            the total reported times  (one of the guidelines used in the
    farm 1320-4 <(?•». 6-72)

-------
    selection of the various compounds).  It should also be noted that
    we did include on the list compounds which have similar structure
    and morphology.  If these two particular compounds are present,
    they could be evaluated at a later date, if necessary.  The
    selection.of the gas-chromotographic columns and preparation
    techniques would certainly remove from solution these two
    compounds.  Therefore they would be available for evaluation
    either in the extract or on the spectral tape.

2.  Chloroalkyl Ethers

    A question was raised on the absence of 2-chloroethyl methy ether
    from the  list of priority pollutants.  It should be noted that
    this particular compound, at present, has no supplier of an
    analytical standard.  The availability of an analytical standard
    is one of the prime criterias which has been used for inclusion on
    the list.  Again th-i's sister compound has been included and if
    present,  would be seen on the spectral tapes or in the
    concentrate.  We feel that this is adequately covered at the
    present time.

3.  Phthalate Esters                         .
                                             , i                      ...
   .This particular category of organic compounds provoked a number of
    consents  and questions from the Advisory Board.  This is a
    volumnious group of organic compounds.  Those that were presented
    were the  most commonly occurring and also probably the most
    prevalent in the environment.  Specific concern was expressed for
    the following; the first being di-n-octyl phthalate which has been
    suggested as a substitute for PCB's.  Upon review, the Agency
    finds that this is a valid concern and therefore we have added it
    to the list of concerned compounds.  Also there was an expression
    of concern over the di-n-propyl phthalate and its exclusion.  At
    the present time there is no analytical standard available for
    this compound, but since it's sister compound is included we feel
    that this compound is adequately covered.  The question of the
    diisobutyl phthalate compound which has really only been seen five
    times in  all the literature was questioned.  It is not a very
    common compound and it is not readily available.  We feel that it
    is not one that we are directly concerned with under this initial
    screening phase of the study.  Likewise diisodecyl phthalate
    compound  was only seen twice in the environment from the
    literature available and we feel that it also doesn't merit
    addition  to the list at this time.  Furthermore, the compound
    diisooctyl phthalate for which there is presently no analytical

-------
standard available, was not included and would not be included at
this time.

PCB's - The original list of priority pollutants contained two
specific arochlor compounds.  The Advisory Committee expressed
some concern over the lack of one or another additional comoounds
and felt very strongly that they should be included on the list.
Primarily  in response to their strong feeling and concern, the
Agency feels that the inclusion of the additional five PCB's for
review and evaluation under the initial program can be justified.
They have  now been  added to the list.

There was  a question raised as to the number of compounds that
were considered  but for which there were no analytical standards
available.  A list  of these compounds is provided in Attachment A
of this memo.  It should be noted that while analytical standards
were not available  for these compounds they also did not meet the
other criterias  established for selection by the Agency at this
time.  Most of them have occurred-at a frequency of less than five
percent of the reported times and therefore would not have been
included anyhow.                           ;
                                           I "i	"
It should  be noted  that the revised list of priority pollutants
contains a number of chances in nomenclature Since the naming of
organic compounds takes several forms we have concluded that we
shall use  the standard reference procedure.  The changes in the
names to the standard naming procedure is reflected in Attachment
B for this particular version of the priority pollutant list.
This list  of revised priority pollutants is shown in Attachment C.
Attachment C reflects the changes made by the Agency in response
to NRDC's  comments  and questions.  We feel that it is both
inclusive  and specific enough that we may carry out the necessary

SUBJECT: Defining Asbestos  for  the BAT Review                  DATE:  .
        —                                                           WAY 131977

FROM:    William A.  Telliard
         Chief, Energy  and  Mining

TO:      Robert B. Schaffer
         D1rector
         Effluent Guidelines  Division
         In an  attempt to  clarify the requirement for the determination
         and quantification  of asbestos in effluent discharges with the
         consent decree, the Energy and Mining Branch has undertaken the
         task of attempting  to define, for the Division, asbestos as it
         relates to our program needs.  It should be understood that
         asbestos  is a generic term that applies to a variety of
         commercially useful hydrated silicate minerals which may or may
         not have  a fibrous  structure.  Table 1 of this memo contains a
         list of some six  common minerals which could be defined as'
         asbestos  type minerals.  The forms represented i'n the table
         express both the  fibrous or asbestiform and the nonfibrous form
         of these  minerals.   Over the last few years, considerable
         controversy has arisen as regards the definition of asbestos.
         The confusion is  partially due to the mineralogical and
         geological definitions versus the environmental and public health
         use of the term.   It is our attempt to define for the purpose of
         the BAT review a  useable definition as it relates to effluent
         discharges.

         A considerable amount of data has been established relating
         health effects and  fibrous asbestos taken in through inhalation
         by various working  groups.  However, there is divided medical
         opinion on the effect of fibrous asbestos as it relates to oral
         injestion and the formation of carcinomas.  The majority of the
         data  that has been  established and presented in the literature
         does  revolve around the asbestos of the fibrous form  or
         asbestiform material.  There is a considerable amount of
         disagreement between various government agencies as well as the
         industry  on what  is an asbestos fiber?  Therefore, we have a two
         part  definition problem, the first being what shall we consider
         to be asbestos? and the second dealing with what shall we
         consider  to be a  fiber?  All of the definitions dealing with the
 EPA Form 1320-4 («••». 4-72)

-------
term fiber  have  raised a great deal of concern.  Many interested
parties have  contended that the relationship of length and
diameter was  not adequate enough to determine a fiber and that in
fact, what  was being observed as a fiber was simply a cleavage
fragment resulting  from the handling or processing of a
nonfibrous  crystaline material.

At present  there are a number of government agencies who are
attempting  to regulate asbestos materials.  Among these are: the
National Institute  for Occupational Safety and Health (NIOSH),
the Occupational  Safety and Health Adminstration (OSHA), the
Mining Enforcement  and Safety Administration (MESA), Federal Mine
Safety Advisory  Committee (FMSAC), and EPA.  In addition,
supplying technical assistance and evaluation is the U.S.
Geological  Survey,  the U.S. Bureau of Mines, and the Bureau of
Standards.  All  of  these agencies have made attempts at defining
what constitutes asbestos.

In an attempt to perhaps to sidestep the fiber question, EPA's
air programs  office uses the corxierical asbestos definition which
defines those compounds in which asbestos is the primary
constituent and  not one in which asbestos is ,a contaminant.
While this  would lend itself primarily for regulation of asbestos
mines and fiber  board manufacture, it does not deal with
operations  such  as  Reserved Mining.

Since there are  so  many other government agencies involved in
this question, a meeting was held on March 11, sponsored by the
Energy and  Mining Branch, to attempt to define asbestos.
Representatives  from the U.S Geological Survey, Bureau of Mines,
the Bureau  of Standards and.respresentatives from both our Duluth
Lab and the Athens  Lab (which has been developing a measurement
method for  asbestos) were present.  Table 2 of this memo contains
a list of the attendees of that meeting and the agency which they
represented.  After considerable discussion, one conclusion was
reached.  There  was general agreement that chrysotile was
probably the  most common form of asbestos and considered by all
those present to be the most representative of asbestiform
materials.

It becomes  apparent then that not only is the question of what is
asbestos  in dispute, but also the question of what is an asbestos
fiber.  Both  questions are open to scientific and medical
discussion  at this  point.  Based on the foregoing conditions and
comments we would like to make the following recommendations:

-------
Recorrmendations

We recommend  that for the purpose of our BAT review the  terra
asbestos shall mean chrysotile.  Chrysotile is the most  commonly
found form  of asbestos and at present there are background  levels
of asbestos in both Canadian and U.S. surface waters that vary
between 10+5  and 10-7 fiber per liter.  The majority, if not  all
of these fibers, are chrysotile.  Chrysotile is a fibrous form  of
serpentine  and it accounts for 95% of the world's asbestos
consumption.  It is the most common form used in construction,
and installation.  Furthermore, it is the most common form  found
in the aquatic environment.

While this  does not resolve question of what is asbestos, as  it
relates to  mining, I believe by restricting our review of
asbestos to chrysotile for the other 20 industries, this would
more than adequately cover the field.  There are a number of
proposed analytical methods for determining chrysotile which
could lend  themselves to quantifying this particular material.
It is therefore, our recommendation that for,the purpose of the
BAT review  that asbestos be defined as chrysotile and that  our
measurements  and quantifications be based on its present or
absence.
