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.

reports of survey analyses of water of all types
effluents, drinking water, surface water, etc.
in the U.S. and abroad, and includes 5500 entries

.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.
(c) Chemical production and number of plants involved
in manufacturing v/as a consideration made.

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.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
SUBJECT:Revised List of Priority Pollutants DATE:
FROM: William Telliard, Chief ^XS ' T Q 1077
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
technical evaluations required under the BAT review.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
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.

PUBLICATION OF TOXIC POUUTANT LIST
.. Pursuant to section 307(a)(l) of the
Federal Water Pollution Control Act
as amended by section 53(a) of the
Clean Water Act of 1977 (Pub. L. 95-
217). the Administrator is required to
-------
r>ubllsli the list of toxic pollutants con-
rf of those listed In Table 1 of
immlttee Print No. 95-30 of the
e of Representatives Committee
on Public Works and Transportation
no later than 30 days after the enact-
','merit of the Act. Nine of the 65 listed
.pollutants (aldrln/dleldrln, benzldine.
cyanldi!. cadmium, DDT, endrln, mer-
. cury, PCBs, and toxaphSne) were pre-
viously listed as toxic pollutants by
the Agency (38 J^R 243/4. September
7. 1073) and toxic pollutant effluent
slamlHrUs have been promulgated for
six of these (42 FR 2538\January 12.
1977, and 42 FR 6532, February 2.
1977).
The list of 65 toxic pollutants was
developed originally by a multi-discl-
" plinary task force of scientists. Follow-
ing submission to the Environmental
' Protection Agency of the conclusions
