                            SECTION I

                     SUMMARY AND CONCLUSIONS
Pursuant to Sections 301, 304, 306, 307, and 501 of the Clean
Water Act and the Settlement Agreement in Natural Resources
Defense Council v. Train 8 ERG 2120 (D.D.C. 1976) modified 12 ERG
1833 (D.D.C. 1979), EPA has collected and analyzed data for
plants in the Aluminum Forming Point Source Category.  There are
no existing effluent limitations or performance standards for
this industry.  This document and the administrative record
provide the technical basis for proposing effluent limitations
guidelines for existing direct dischargers, pretreatment stan-
dards for new and existing indirect dischargers, and standards of
performance for new source direct dischargers.

Two hundred seventy-seven plants employing 28,500 people make up
this category.  Of the 277 plants, 58 discharge directly to
rivers, lakes, or streams; 66 discharge to publicly owned treat-
ment works (POTW); and 153 do not discharge process wastewater.

The Agency developed a data collection portfolio (dcp) to collect
information regarding plant size, age, production, the production
processes used, the quantity of process wastewater used and dis-
charged, wastewater treatment in-place, and disposal practices at
plants practicing aluminum forming.  The dcp' s were sent to 580
firms known or believed to perform aluminum forming, 95 percent
of these firms responded,

EPA sampled the raw (untreated) and treated process wastewater at
20 aluminum forming plants.  Screen sampling was performed at
four facilities, each representing one of the major manufacturing
processes of rolling, extruding, forging, and drawing.  Samples
were collected from wastewater sources associated with the major
manufacturing processes, as well as any associated processes,
including cleaning, etching, solution heat treatment, and anneal-
ing, among others.  Each of the samples was analyzed to determine
the presence or absence, and if present, the concentration of 129
toxic priority pollutants, plus conventional and selected noncon-
ventional pollutants.  The remaining 16 plants were sampled to
verify the findings and strengthen the data base.

The Agency examined the rate of production and wastewater genera-
tion reported in the dcp' s for each aluminum forming operation.
These data combined with the wastewater characteristics deter-
mined during sampling became the principle bases for subcatego-
rizing this category.  Based on these data, the most appropriate

-------
approach to subcategorizing this category is by the major manu-
facturing processes.  In addition, a review of the use of lubri-
cants in rolling and drawing showed that these operations needed
to be segmented according to whether neat oils or soaps and emul-
sions are used.  A neat oil is a pure oil which when spent of its
lubricating properties, can be hauled to an oil reclaimer or used
as fuel in the plant.  Emulsions and soaps are mixtures of oils
and water.  When these lubricants are spent, plants can contract
haul them to a disposal site, or treat them to remove the oil and
discharge or reuse the water.  The aluminum forming category is
subcategorized based on manufacturing processes and wastewater
characteristics, resulting in six subcategories:  rolling with
neat oils, rolling with emulsions, extrusion, forging, drawing
with neat oils, and drawing with emulsions or soaps.

Each subcategory is divided into two segments.  The first seg-
ment, called the core, consists of the specific forming operation
and related operations that are an integral part of the forming
process.  The core also includes operations that may be found in
conjunction with the forming operation but do not discharge
wastewater.  The effluent flow from the core for each of the sub-
categories is production normalized or related to the mass of
aluminum processed through the forming operation, and the limita-
tions at BPT and BAT are based on the effluent flow and the
treatment effectiveness.

The second segment of each subcategory consists of ancillary
operations that generate wastewater and when practiced are an
integral part of the aluminum forming process.  These ancillary
operations, such as solution heat treatment, cleaning or etching,
and casting, are practiced to achieve desired characteristics or
finishes on the aluminum products and can be characterized by the
generation of large volumes of wastewater.  Because they are not
found at every plant in a subcategory and they are not always
unique to a specific subcategory, they are not included in the
core.  Instead, a separate limitation is proposed for the waste
streams generated by these ancillary operations and normalized by
the mass of aluminum processed through the ancillary operation.
An aluminum forming plant would be permitted to discharge pollu-
tants equivalent to the sum of the limitations established for
the core and the ancillary operation(s) practiced at the plant.

EPA used the subcategories to study the characteristics of the
untreated wastewater for the purpose of selecting in-plant
control and end-of-pipe treatment options.  The pollutants
present at levels of most significant concentration are:

        Cadmium,
        Chromium,
        Cyanide,

-------
        Copper,
        Lead,
     -  Nickel,
        Zinc,
        Aluminum,
        Oil and grease,
        Suspended solids, and
        Specific toxic organics.

The Agency studied various end-of-pipe technologies to treat the
above pollutants, including:

        Chemical precipitation and sedimentation (lime and
        settle),

        Oil skimming,

        Chromium reduction,

        Cyanide oxidation or precipitation,

        Multimedia filtration,

        Carbon adsorption,

        Reverse osmosis,

        Chemical emulsion breaking, and

        Thermal emulsion breaking.

EPA also studied various types of in-plant controls reported in
the dcp's and observed during sampling.  The in-plant controls
studied included:

        Recycle of contact cooling water and scrubber liquor,

        Countercurrent cascade rinsing,

        Hauling or regeneration of chemical baths for cleaning
        or etching, and

        Alternative fluxing and degassing methods which do not
        require wet scrubbing.

Engineering costs were prepared for each of the treatment options
considered for each plant in the category.  These costs were then
used by the Agency to estimate the impact of implementing the
various options on the industry.  For each subcategory for each
control and treatment option, the number of potential closures,

-------
number of employees affected, and impact on price were estimated.
These results are reported in the Economic Impact Analysis of
Proposed Effluent Limitations and Standards for the Aluminum
Forming Industry.

The Agency has also examined the performance of each control and
treatment option.  The Agency has identified BPT to represent the
average of the best existing technology.  Metals removal based on
lime and settle technology is the basis for the BPT limitations
on zinc, aluminum, and suspended solids, while oil removal by
skimming and chemical emulsion breaking were selected as the
basis for the oil and grease limitation.  Chromium reduction may
be necessary to achieve the limitation on chromium.  Cyanide
removal may be necessary if cyanide is present in wastewaters.

The goal of BAT is to achieve increased levels of toxic pollutant
removal.  For BAT, the Agency selected the same end-of-pipe
treatment as BPT in conjunction with several in-process control
technologies which include recycle of process water from scrub-
bing and contact cooling waste streams, countercurrent cascade
rinsing, regeneration or hauling of chemical baths used for
cleaning or etching, and alternate fluxing and desgassing methods
to achieve zero discharge.  All of the control technologies, as
well as the end-of-pipe treatment, except for cyanide removal,
are currently being applied to aluminum forming process waste-
water.  The Agency is considering promulgating BAT on the basis
of the addition of polishing filters.

BDT, which is the technical basis of NSPS is similar to BAT with
the addition of polishing filters.  In selecting BDT, EPA recog-
nizes that new plants have the opportunity to implement the best
and most efficient manufacturing processes and control and
treatment technology.

For PSES, the Agency selected the same technology as BAT, which
is BPT end-of-pipe treatment in conjunction with several
in-process flow reduction control techniques.  For PSNS, the
Agency selected the same technology as NSPS, which is BPT
end-of-pipe treatment with the addition of polishing filters in
conjunction with several in-process flow reduction control tech-
niques.  The Agency is considering promulgating PSES on the basis
of the addition of polishing filters.

                            SECTION II

                         RECOMMENDATIONS
    EPA has divided the aluminum forming category into six
    subcategories for the purpose of effluent limitations and
    standards.  These subcategories are:

    -  Rolling With Neat Oils
       Rolling With Emulsions
       Extrusion
    -  Forging
       Drawing With Neat Oils
       Drawing With Emulsions or Soaps

    BPT is being proposed based on the treatment effectiveness
    achievable by the application of oil skimming and chemical
    precipitation and sedimentation (lime and settle) technology.
    The following BPT effluent limitations are being proposed for
    existing sources:

    achievable by the application of oil skimming and chemical
    precipitation, sedimentation and filtration (lime,  settle,
    and filter) technology and in-process flow reduction control
    methods.  The following pretreatment standards are  being
    proposed for new sources:

7.  EPA is considering promulgating BAT effluent limitations
    more stringent than the limitations now proposed for BAT.
    The limitations are based upon the treatment effectiveness
    achieved through the control and treatment used to form the
    basis of BAT, with the addition of filtration.   In the event
    that the Agency decides to promulgate these more stringent
    limitations, the following would apply:

8.  EPA is considering promulgating PSES standards more stringent
    than the standards now proposed for PSES.   The standards are
    based upon the treatment effectiveness achieved through the
    control and treatment used to form the basis of PSES,  with
    the addition of filtration.  In the event that the Agency
    decides to promulgate these more stringent standards,  the
    following would apply:

                           SECTION III

                           INTRODUCTION
PURPOSE AND AUTHORITY

The Federal Water Pollution Control Act Amendments of 1972
established a comprehensive program to "restore and maintain the
chemical, physical, and biological integrity of the Nation's
waters," under Section 101(a).  By July 1, 1977, existing indus-
trial dischargers were required to achieve "effluent limitations
requiring the application of the best practicable control tech-
nology currently available" (BPT), under Section 301(b)(1) (A) ;
and by July 1, 1983, these dischargers were required to achieve
"effluent limitations requiring the application of the best
available technology economically achievable .  . . which will
result in reasonable further progress toward the national goal of
eliminating the discharge of all pollutants" (BAT), under Section
301(b)(2)(A).   New industrial direct dischargers were required to
comply with Section 306 new source performance  standards (NSPS),
based on best available demonstrated technology; existing and new
dischargers to publicly owned treatment works (POTW) were subject
to pretreatment standards under Sections 307(b) (PSES) and (c)
(PSNS), respectively, of the Act.  While the requirements for
direct dischargers were to be incorporated into National Pollu-
tant Discharge Elimination System (NPDES) permits issued under
Section 402 of the Act, pretreatment standards were made enforce-
able directly against discharges to a POTW (indirect discharg-
ers).  Although Section 402(a)(1) of the 1972 Act authorized the
setting of NPDES permit requirements for direct dischargers on a
case-by-case basis, Congress intended that, for the most part,
control requirements would be based on the degree of effluent
reduction attainable through the application of BPT and BAT.
Moreover, Sections 304(c) and 306 of the Act required promulga-
tion of regulations for new sources (NSPS); and Sections 304(f),
307(b), and 307(c) required promulgation of regulations for
pretreatment standards.  In addition to these regulations for
designated industry categories, Section 307(a) of the Act
required the Administrator to promulgate effluent standards
applicable to all dischargers of toxic pollutants.  Finally,
Section 301 (a) of the Act authorized the Administrator to pre-
scribe any additional regulations "necessary to carry out his
functions ' under the Act.

EPA was unable to promulgate many of these regulations by the
dates contained in the Act.  In 1976, EPA was sued by several
environmental groups and in settlement of this lawsuit, EPA and
the plaintiffs executed a "Settlement Agreement," which was
approved by the Court.  This Agreement required EPA to develop a
                                79

-------
program and adhere to a schedule for promulgating 21 major
industries' BAT effluent limitations guidelines, pretreatment
standards, and new source performance standards for 65 "priority"
pollutants and classes of pollutants.  See Settlement Agreement
in Natural Resources Defense Council, Inc. v. Train, 8 ERG 2120
(D.D.C. 1976), modified 12 ERG 1833 (D.P.C. 1979).

On December 27, 1977, the President signed into law amendments to
the Federal Water Pollution Control Act (P.L. 95-217).  The Act,
as amended, is commonly referred to as the Clean Water Act.
Although this Act makes several important changes in the federal
water pollution control program, its most significant feature is
its incorporation of several of the basic elements of the Settle-
ment Agreement program for toxic pollution control.  Sections
301(b)(2)(A) and 301 (b) (2) (C) of the Act now require the achieve-
ment, by July 1, 1984, of effluent limitations requiring applica-
tion of BAT for toxic pollutants, including the 65 priority pol-
lutants and classes of pollutants (the same priority pollutants
as listed in Natural Resources Defense Council v. Train), which
Congress declared toxic under Section 307(a) of the Act.  Like-
wise, EPA's programs for new source performance standards and
pretreatment standards are now aimed principally at control of
these toxic pollutants.  Moreover, to strengthen the toxics
control program, Congress added Section 304(e) to the Act,
authorizing the Administrator to prescribe "best management
practices" (BMP) to prevent the release of toxic and hazardous
pollutants from plant site runoff, spillage or leaks, sludge or
waste disposal, and drainage from raw material storage associated
with, or ancillary to, the manufacturing or treatment process.

In keeping with its emphasis on toxic pollutants, the Clean Water
Act also revised the control program for nontoxic pollutants.
Instead of BAT for "conventional  pollutants identified under
Section 304(a)(4) (including biological oxygen demand, suspended
solids, oil and grease, fecal coliform, and pH), the new Section
301 (b)(2)(E) requires achievement, by July 1, 1984, of "effluent
limitations requiring the application of the best conventional
pollutant control technology  (BCT).  The factors considered in
assessing BCT for an industry include a two-part "cost-
reasonableness" test [Section 304(b)(4)(B)], American Paper
Institute v. EPA, 660 F.2d 954 (4th Cir. 1981T  The first part
compares the cost for private industry to reduce its conventional
pollutants with the costs to publicly owned treatment works for
similar levels of reduction in their discharge of pollutants.
The second part examines the cost effectiveness of additional
industrial treatment beyond BPT.  For nontoxic. nonconventional
pollutants, Sections 301(b)(2)(A) and (b)(2)(F) require achieve-
ment of BAT effluent limitations within three years after their
establishment or not later than July 1, 1984.
                                80

-------
The purpose of this report is to provide the supporting technical
data regarding water use, pollutants, and treatment technologies
for BPT, BAT, NSPS, PSES, or PSNS effluent limitations that EPA
is proposing for the aluminum forming category under Sections
301, 304, 306, 307, and 501 of the Clean Water Act.

METHODOLOGY

Approach of Study

EPA gathered and evaluated technical data in the course of
developing these guidelines in order to perform the following
tasks:

     1.  To profile the category with regard to the production,
         manufacturing processes, geographical distribution,
         potential wastewater streams, and discharge mode of
         aluminum forming plants.

     2.  To subcategorize, if necessary, in order to permit
         regulation of the aluminum forming category in an
         equitable and manageable way.  This was done by taking
         all of the factors mentioned above plus others into
         account.

     3.  To characterize wastewater, detailing water use, waste-
         water discharge, and the occurrence of priority, conven-
         tional, and nonconventional pollutants, in waste streams
         from aluminum forming processes.

     4.  To select pollutant parameters — those priority or con-
         ventional pollutants present at significant concentra-
         tions in wastewater streams — that should be considered
         for regulation.

     5.  To consider control and treatment technologies and
         select alternative methods for reducing pollutant dis-
         charge in this category.

     6.  To evaluate the costs of implementing the alternative
         control and treatment technologies.

     7.  To present possible regulatory alternatives.

Data Collection and Methods of Evaluation

Literature Review.  EPA reviewed and evaluated existing litera-
ture for background information to clarify and define various
aspects of the aluminum forming category and to determine general
characteristics and trends in production processes and wastewater
treatment technology.  Review of current literature continued
                                81

-------
throughout the development of these guidelines.  Information
gathered in this review was used, along with information from
other sources as discussed below, in the following specific
areas:

        Introduction (Section III) - description of production
        processes and the associated lubricants and wastewater
        streams.

        Subcategorization (Section IV) - identification of
        differences in manufacturing process technology and their
        potential effect on associated wastewater streams.

        Selection of Pollutant Parameters (Section VI) - infor-
        mation regarding the toxicity and potential sources of
        the pollutants identified in wastewater from aluminum
        forming processes.

        Control and Treatment Technology (Section VII) - infor-
        mation on alternative controls and treatments and
        corresponding effects on pollutant removal.

        Costs (Section VIII) - formulation of the methodology
        and equations for determining the current capital and
        annual costs to apply the selected treatment alterna-
        tives.

Existing Data.  Information related to aluminum forming pro-
cesses, wastewater, or wastewater treatment technology was
compiled from a number of sources.  Technical data gathered for
development of guidelines for related categories, such as the
nonferrous metals category, were reviewed and incorporated into
this guideline, where applicable.

The concentration or mass loading of pollutant parameters in
wastewater effluent discharges are monitored and reported as
required by individual state agencies.  These historical data are
available from NPDES monitoring reports.

Frequent contact has been maintained with industry personnel.
Contributions from these -sources were particularly useful for
clarifying differences in production processes.

Data Collection Portfolios.  The aluminum forming plants were
surveyed to gather information regarding plant size, age and
production, the production processes used, and the quantity,
treatment, and disposal of wastewater generated at these plants.
This information was requested in data collection portfolios
(dcp's) mailed to all companies known or believed to be involved
in the forming of aluminum or aluminum alloys.  The original
mailing list was compiled from the following sources:
                                82

-------
        U.S. Department of Commerce, Directory of Aluminum
        Suppliers in the United States, Revised January 1978.

        Architectural Aluminum Manufacturers Association,
        Membership Directory, 1977.

        Aluminum Foil Containing Manufacturers Association,
        Membership Roster as of May 1, 1978.

        Dun Sc Bradstreet, Inc., Million Dollar Directory, 1978.

In all, dcp's were sent to 580 firms.  Approximately 95 percent
of the companies responded to the survey.  In many cases,
companies contacted were not actually members of the aluminum
forming category as it is defined by the Agency.  Where firms had
aluminum forming operations at more than one location, a dcp was
returned for each plant.  A total of 279 dcp's applicable to the
aluminum forming category were returned.  Two plants have since
ceased aluminum forming operations, therefore, a total of 277
plants were included in the data base.  In cases where the dcp
responses were incomplete or unclear, additional information was
requested by telephone or letter.

The dcp responses were interpreted individually, and the follow-
ing data were documented for future reference and evaluation:

        Company name, plant address, and name of the contact
        listed in the dcp.

        Plant discharge status as direct (to surface water),
        indirect (to POTV), or zero discharge.

        Production process streams present at the plant, as well
        as associated flow rates; production rates; operating
        hours; wastewater treatment, reuse, or disposal methods;
        the quantity and nature of process chemicals; and the
        percent of any soluble oil used in emulsified mixtures.

        Capital and annual treatment costs.

        Availability of pollutant monitoring data provided by the
        plant.

The summary listing of this information provided a consistent,
systematic method of evaluating and summarizing the dcp
responses.  In addition, procedures were developed to simplify
subsequent analyses.  The procedures developed had the following
capabilities:

        Selection and listing of plants containing specific pro-
        duction process streams or treatment technologies.
                                83

-------
        Summation of the number of plants containing specific
        process stream and treatment combinations.

        Calculation of the percent recycle present for specific
        streams and summation of the number of plants recycling
        this stream within various percent recycle ranges.

        Calculation of annual production values associated with
        each process stream and summation of the number of plants
        with these process streams having production values
        within various ranges.

        Calculation of water use and blowdown from individual
        process streams.

The calculated information and summaries were important and
frequently used in the development of this guideline.  Summaries
were used in the category profile, evaluation of subcategoriza-
tion, and analysis of in-place treatment and control technolo-
gies.  Calculated information was used in the determination of
water use and discharge values for the conversion of pollutant
concentrations to mass loadings.

GENERAL PROFILE OF THE ALUMINUM FORMING CATEGORY

There are a number of advantages to using aluminum in a wide
variety of products.  Chief among these are that aluminum is
lightweight, tough, resistant to corrosion, and has high elec-
trical conductivity.  The major uses of aluminum are in the
building and construction industry, transportation industries,
the electrical products industry, and in container and package
manufacturing.

Products manufactured by aluminum forming operations generally
serve as stock for subsequent fabricating operations, as shown in
Figure III-l.  Cast ingots and billets are the starting point for
making sheet and plate, extrusions, forgings, and rod, for use in
drawing operations.  Rolled aluminum sheet and plate can be used
as stock for stampings, can blanks, and roll formed products; as
finished products in building, ship and aircraft construction; or
as foil.  Extrusions can be used as raw stock for forging and
drawing; to fabricate final products, such as bumpers, window
frames, or light standards; or can be sold as final products,
such as beams or extruded tubing.  Forgings are either sold as
consumer products or used as parts in the production of
machinery, aircraft, and engines.

The variety and type of products produced at one location has a
large influence on the production capacity of the forming plant,
the number of people employed, and the amount of water used.  The
                               84

-------
capital intensive investment, large source of energy required,
and specialized labor force involved in making aluminum sheet,
strip, foil,'and plate products limit the number of facilities
available to meet the demand for these sheet products.  Most
sheet products are made at a few large plants owned by major  com-
panies.  Table III-l summarizes data about these and other prod-
ucts of aluminum forming.  A variety of sheet products are often
produced at the same location.  Other products, such as billets
and extrusions, are frequently made in conjunction with the
rolled products at these plants.

Tubes, rod, cable, and wire are produced at sites that range  in
size from very large to small.  On a mass basis most drawn
products are produced by a few large companies or factories,
while the remainder are produced by a number of smaller firms.
Employment varies from a few to several hundred people.

Extrusion and forging processes, which produce a wide variety of
products, do not require large facilities.  Consequently, extru-
sion and forging products are formed at many sites by a number of
companies.  Production and employment at facilities using either
type of process range from small plants with few workers to large
plants with hundreds of employees.  Some extrusion plants have
other forming operations as well.  Forging; however, is usually
performed by plants that are not involved in other processes.

Casting in the aluminum forming category, both continuous and
direct chill, is done prior to another operation, such as rolling
or extrusion.  Aluminum billets or ingots are rarely cast at
aluminum forming plants for sale to other industries or firms.
Stationary casting in this industry usually involves only melted
in-plant scrap aluminum.  The ingots, frequently called pigs  or
sows, produced from stationary casting are normally remelted  and
used as stock for continuous or direct chill casting.

The dcp responses indicate that 156 companies own 277 aluminum
forming plants.  Five of the companies own 22 percent of the
plants, and 16 companies own 42 percent of the production
facilities.

Employment data is given in the dcp responses for 248 plants  (89
percent of the total).  These plants report a total of 28,557
workers involved in aluminum forming.  Employment at the indi-
vidual sites ranges from one to 2,100 people.  The employment
distribution of aluminum forming workers at the 248 plants is:
69 percent employ fewer than 100 people in aluminum forming
operations; 83 percent employ fewer than 200 people in this
capacity; and 95 percent employ fewer than 500 people.

-------
Reported production of formed aluminum at individual plant sites
ranged from  .09 kkg (0.1 ton) to almost 360,000 kkg (400,000
tons) during 1977.  The aluminum forming production distribution
for the 249 plants, for which 1977 production data were availa-
ble , is summarized as follows:   75 percent produced less than
9,000 kkg (10,000 tons); 96 percent produced less than 45,000 kkg
(50,000 tons); and 98 percent produced less than 180,000 kkg
(200,000 tons).

Aluminum forming plants are not limited to any one geographical
location.  As shown in Figure 1II-2, plants are found throughout
most of the United States, but the majority are located east of
the Mississippi River.  Population density is not a limiting
factor in plant location.  Aluminum forming plants tend to be
more common in urban areas, but they are frequently found in
rural areas as well.

The majority of the aluminum forming plants (55 percent) that
reported the age of their facility indicated they were built
since 1957.  Table 1II-2 shows the age distribution of aluminum
forming plants according to their classification as direct, indi-
rect, and zero discharge type.   The dates of most recent modifi-
cation were reported by 230 plants.  The distribution of facili-
ties according to time elapsed since their last major plant
modification is given in Table III-3.  Of the 277 aluminum
forming plants, 44 percent have been modified since 1972.

One hundred fifty-three plants indicated that no wastewater from
aluminum forming operations is discharged to either surface
waters or a POTW.  Of the remaining 124, 58 discharge an effluent
from aluminum forming directly to surface waters, and 66 dis-
charge indirectly, sending aluminum forming effluent through a
POTW.  The volume of aluminum forming wastewater discharged by
plants in this category ranges from 0 to 2,896,000 liters per
hour (0 to 765,000 gal/hr).  The mean volume is approximately
74,000 liters per hour (19,540 gal/hr) for those plants having
discharges.  Two hundred fifty-nine plants supplied wastewater
data.  This is less than the total number of aluminum forming
plants in the category because several plants did not provide
enough information to calculate the flows.  Of these 259 plants,
65 percent reported no wastewater discharge from aluminum forming
operations; 90 percent discharge less than 19,000 liters per hour
(5,000 gal/hr); and 98 percent discharge less than 190,000 liters
per hour (50,000 gal/hr).  There is no correlation between over-
all water use and total aluminum production; however, correla-
tions can be developed between water use or wastewater discharge
and production on a process basis.  This is discussed further in
Section V.
                               86

-------
Sixty plants reported some form of treatment for wastewater from
aluminum forming processes.  Another 13 plants mentioned treat-
ment only for wastes not covered under the aluminum forming
category.  The most common forms of wastewater treatment are pH
adjustment, clarification, gravity oil separation (skimming), and
lagooning.  In-line filtration and cooling towers are frequently
used as wastewater controls.  Oily wastes are separated into oil
and water fractions by emulsion breaking using heat or chemicals.
Gravity separation is frequently used to separate neat oil and
broken emulsions from the water fraction.  The oil portion is
usually removed by a contractor, although some plants dispose of
it by land application, incineration, or lagooning.  Sludges
generally are not thickened, but are disposed of without treat-
ment; however, vacuum and pressure filters, centrifuges, and
drying beds are occasionally used. Sludge disposal methods
include landfill and contractor removal.  Disposal of wastewater
is being accomplished by discharge to surface waters or a POTW,
by contractor removal, or by land application.

ALUMINUM FORMING PROCESSES

Aluminum forming processes, for the purpose of this guideline,
are those manufacturing operations in which aluminum or aluminum
alloys are shaped into semifinished or mill products by hot or
cold working.  These manufacturing operations, called core opera-
tions (see Section IV), include rolling, extruding, forging and
drawing of aluminum.  Associated processes, called ancillary
operations, such as the casting of aluminum alloys for subsequent
forming, heat treatment, cleaning, and etching are also included.

Water is used in combination with oil lubricants, surface pro-
cessing chemicals, and in contact cooling as a part of these
operations in order to achieve specified desired metal character-
istics (i.e., tensile strength, malleability, specific surface
properties).  Water may also be used in wet air pollution control
devices (i.e., wet scrubbers, electrostatic precipitators) to
collect fumes and particulates.  A further discussion of waste-
water sources from aluminum forming processes is presented in
Section V.  Regulatory flow allowances for waste streams under
BPT and BAT are presented and discussed in Sections IX and X,
respectively.

EPA recognizes that plants sometimes combine nonaluminum forming
process and nonprocess wastewater prior to treatment and
discharge.  Pollutant discharge allowances will be established
only for aluminum forming process wastewater, not the nonaluminum
process or nonprocess wastewaters under this regulation.  The
flows and wastewater characteristics are a function of the plant
layout and water handling practices.  As a result, the pollutant
discharge effluent limitation for nonaluminum forming wastewater
                               87

-------
streams will be prepared by the permitting authority.  These
wastewaters are not further discussed in this document or covered
by the regulation.

CORE OPERATIONS

Rolling

The rolling process is used to transform cast aluminum ingot into
any one of a number of intermediate or final products.  Pressure
exerted by the rollers as aluminum is passed between them reduces
the thickness in the metal and may cause work hardening.  Square
ingots cast by the direct chill method described previously are
often used in the production of wire, rod, and bar.  The ingots
are usually reduced by hot rolling to elongated forms, known as
blooms.  Additional hot or cold rolling may be used to produce
rod, bar, or wire.  Rod is defined as having a solid round cross
section 0.95 cm (3/8 inch) or more in diameter.  Bar is also
identified by a cross section with 0.95 cm (3.8 inch) or more
between two parallel sides, but it is not round.  Wire is
characterized by a diameter of less than 0.95 cm (3/8 inch).

Although the design of rolling mills varies considerably, the
principle behind the proces s is es sent ially the s ame.  At the
rolling mill, aluminum is passed through a set of rolls that
reduces the thickness of the metal and increases its length.  Two
common roll configurations are shown in Figure I1I-3.  Multiple
passes through the rolls are usually required, and mills are
frequently designed to allow rolling in the reverse direction.
For wire, rod, and bar products, grooves in the upper and lower
rolls account for the various reductions in cross sectional area.

At sheet mills, ingots are heated to temperatures ranging from
400 to 500°C and hot rolled to form slabs.  Hot rolling is
usually followed by further reduction of thickness on a cold
rolling mill.  The hot rolled product is generally limited to
plate [typically defined as being greater than or equal to 6.3 mm
(0.25 inch) thick].  Cold rolled products are classified as sheet
[from 6.3 to 0.15 mm (0.249 to 0.007 inch) thick] and foil [below
0.15 mm (0.006 inch) thick].

As will be discussed later in this section, heat treatment is
usually required before and between stages of the rolling pro-
ces s.   Ingots are usually made homogeneous in grain structure
prior to hot rolling in order to remove the effects of casting on
the aluminum1s mechanical properties.  Annealing is typically
required between passes or after cold rolling to keep the metal
ductile and remove the effects of work hardening.  The kind and
degree of heat treatment applied depends on the alloy involved,
the nature of the rolling operation, and the properties desired
in the product.

-------
It is necessary to use a cooling and lubricating compound during
rolling to prevent excessive wear on the rolls, to prevent adhe-
sion of aluminum to the rolls, and to maintain a suitable and
uniform rolling temperature.  Oil-in-water emulsions, stabilized
with emulsifying agents such as soaps and other polar organic
materials, are used for this purpose in hot rolling operations.
Emulsion concentrations usually vary between 5 and 10 percent
oil.   Evaporation of the lubricant as it is sprayed on the hot
metal serves to cool the rolling process.  Mist eliminators may
be used to recover rolling emulsions that are dispersed to the
atmosphere.  The emulsions are typically filtered to remove metal
fines and other contaminants and recirculated through the mills.
The use of deionized water to replace evaporative and carryover
losses and the addition of bactericides and antioxidizing agents
are practiced at many plants to increase the life of the emul-
sions.  Nevertheless, the emulsions eventually become rancid or
degraded and must be eliminated from circulation either by con-
tinuous bleed or periodic discharge.  Most cold rolling opera-
tions use mineral oil or kerosene-based lubricants rather than
water-based compounds to avoid staining the aluminum surface;
however, emulsions are used for cold rolling in other countries
and,  to a limited extent, in the United States.  As in hot
rolling, mist eliminators are commonly used to collect cold
rolling mists in order to recover the rolling oils for reuse.

The steel rolls used in hot and cold rolling operations require
periodic machining to remove aluminum buildup and to grind away
any cracks or imperfections that appear on the surface of the
rolls.  Although the survey of the industry indicated that roll
grinding with water is practiced, the use of an oil-in-water
emulsion is much more common.  This emulsion is usually recycled
and periodically discharged after treatment with other emulsified
waste streams at the plant.  Some plants have demonstrated that
the discharge of roll grinding emulsions can be avoided by
in-line removal using magnetic separation of steel fines from the
emulsion or filtration techniques.  With this treatment, the
emulsion can be recycled indefinitely with no bleed stream other
than carryover on the rolls.

Of the plants surveyed, 57 have rolling operations.  Twenty-three
of these discharge wastewater directly to surface water, nine
discharge indirectly through a POTW, and 25 do not discharge
process wastewater.  The geographical location of plants with
aluminum rolling operations is presented in Figure III-4.  The
annual production of rolled aluminum at these plants during 1977
varied from 270 to 580,000 kkg (300 to 640,000 tons), with a mean
value of 200,000 kkg (110,000 tons).  The production distribution
is summarized as follows:  of the 45 rolling operations for which
1977 production data were available, 36 percent produced less
than 18,000 kkg (20,000 tons) of aluminum and aluminum alloys;
73 percent produced less than 90,000 kkg (100,000 tons); and
90 percent produced less than 360,000 kkg (400,000 tons).
                               89

-------
Extrusion

In the extrusion process, high pressures are applied to a cast
billet of aluminum, forcing the metal to flow througji a die ori-
fice.  The resulting product is an elongated shape or tube of
uniform cross sectional area.  Extrusions are manufactured using
either a mechanical or a hydraulic extrusion press.

There are two basic methods of extrusion practiced in the
aluminum forming category:

        direct extrusion, and
        indirect extrusion.

The direct extrusion process is shown schematically in Figure
III-5.  A heated cylindrical billet is placed into the ingot
chamber, and the dummy block and ram are placed into position
behind it.  Pressure is exerted on the ram by hydraulic or
mechanical means, forcing the metal to flow through the die
opening.  The extrusion is sawed off next to the die, and the
dummy block and ingot butt are released.  Hollow shapes are
produced with the use of a mandrel postioned in the die opening
so that the aluminum is forced to flow around it.  A less common
technique, indirect extrusion, is similar, except that in this
method, the die is forced against the billet extruding the metal
in the opposite direction through the ram stem.  A dummy block is
not used in indirect extrusion.

Although aluminum can be extruded cold, it is usually first
heated to a temperature ranging from 375 to 525 C, so that little
work hardening will be imposed on the product.  Heat treatment is
frequently used after extrusion to attain the desired mechanical
properties.  Heat treatment techniques will be described later in
this section.  At some plants, contact cooling of the extrusion,
sometimes called press heat treatment quench, is practiced as it
leaves the press.  This can be done in one of three ways:  with a
water spray near the die, by immersion in a water tank adjacent
to the runout table, or by passing the aluminum through a water
wall.  A third wastewater stream which may be associated with the
extrusion process is dummy block cooling water.  Following an
extrusion, the dummy block drops from the press, and is cooled
before being used again.  Air cooling is most commonly used for
this purpose, but water is used at a few plants to quench the
dummy blocks.

The extrusion process requires the use of a lubricant to prevent
adhesion of the aluminum to the die and ingot container walls.
In hot extrusion, limited amounts of lubricant are applied to the
ram and die face or to the billet ends.  For cold extrusion, the
                               90

-------
container walls, billet surfaces, and die orifice must be lubri-
cated with a thin film of viscous or solid lubricant.  The lubri-
cant most commonly used in extrusion is graphite in an oil or
water base.  A less common technique, spraying liquid nitrogen on
the billet prior to extrusion, is also used.  The nitrogen
vaporizes during the extrusion process and acts as a lubricant.

The steel dies used in the extrusion process require frequent
dressing and repairing to ensure the necessary dimensional pre-
cision and surface quality of the product.  The aluminum that has
adhered to the die orifice is typically removed by soaking the
die in a caustic solution.  The aluminum is dissolved and later
precipitated as aluminum oxide.  The caustic bath is followed by
a water rinse of the dies.  The rinse is frequently discharged as
a wastewater stream.

In all, 163 extrusion plants were identified in this survey.  0£
these, 85 indicated that no wastewater is discharged from alumi-
num forming operations at the plant; 38 identified themselves as
direct dischargers; and 40 indicated indirect discharge of the
process effluent to a POTW.  In subsequent investigation of
extrusion practices, it became apparent that these figures may be
misleading.  At many of the extrusion plants contacted, personnel
did not realize that die cleaning rinse water was considered to
be an aluminum forming wastewater stream as defined in this
study.  For this reason, some of the plants classified as zero
discharge are believed to be discharging this effluent stream
either to surface waters or to a POTW.

The geographical location of the extrusion plants is shown in
Figure III-6.  Annual production of extruded products from these
plants ranged between 6.8 and 68,000 kkg (7.5 and 75,000 tons) in
1977.  The production distribution is summarized as follows:  of
the 157 extrusion operations for which 1977 production data were
available, 58 percent produced less than 4,500 kkg (5,000 tons)
of aluminum and aluminum alloys; 81 percent produced less than
9,000 kkg  (10,000 tons); and 92 percent produced less than 18,000
kkg (20,000 tons).

Forging

Forging is a process in which aluminum is formed, usually hot,
into shapes by employing compressive forces.  The actual forging
process is a dry operation.  There are four basic methods of
forging practiced in the aluminum forming category:

        Closed die forging,
        Open die forging,
        Rolled ring forging, and
        Cold impact extruding.
                               91

-------
In each of these techniques, pressure is exerted on dies or
rolls, forcing the heated stock to take the desired shape.  The
first three methods are shown schematically in Figure III-7.

Closed die forging, the most prevalent method, is accomplished by
hammering or squeezing the aluminum between two steel dies, one
fixed to the hammer or press ram and the other to the anvil.
Forging hammers, mechanical presses, and hydraulic presses can be
used for the closed die forging of aluminum alloys.  The heated
stock is placed in the lower die and, by one or more blows of the
ram, forced to take the shape of the die set.  In closed-die
forging, aluminum is shaped entirely within the cavity created by
these two dies.  The die set comes together to completely enclose
the forging, giving lateral restraining to the flow of the metal.

The process of open die forging is similar to that described
above, but in this method, the shape of the forging is determined
by manually turning the stock and regulating the blows of the
hammer or strokes of the press.  Open die forging requires a
great deal of skill and only simple, roughly shaped forgings can
be produced.  Its use is usually restricted to items produced in
small quantities and to development work where the cost of making
closed type dies is prohibitive.

The process of rolled ring forging is used in the manufacture of
seamless rings.  A hollow cylindrical billet is rotated between a
mandrel and pressure roll to reduce its thickness and increase
its diameter.

The process of impact extruding is performed by placing a cut-off
piece of aluminum in a bottom die.  A top die consisting of a
round or rectangular punch and fastened to the press ram is
driven into the aluminum slug, causing the aluminum to be driven
up around the top punch.  Usually, the aluminum adheres to the
punch and must be stripped off as the press ram rises.

Proper lubrication of the dies is essential in forging aluminum
alloys.  Collodial graphite in either a water or an oil medium is
usually sprayed onto the dies for this purpose.  Particulates and
smoke may be generated from the partial combustion of oil-based
lubricants as they contact the hot forging dies.  In those cases,
air pollution controls may be required.  Baghouses, wet scrub-
bers, and commercially available dry scrubbers are in use at
aluminum forming facilities.

Forging of aluminum alloys is practiced at 16 plants located as
shown in Figure III-8.  Of those plants, 12 discharge aluminum
forming wastewater indirectly to a POTW, and the remaining four
plants have no discharge of process wastewater.  The production
distribution is summarized as follows:  of the 15 forging opera-
tions for which 1977 production data were available, 67 percent
                               92

-------
produced less than 900 kkg (1,000 tons) of aluminum and aluminum
alloys; 80 percent produced less than 4,500 kkg (5,000 tons); and
87 percent produced less than 9,000 kkg (10,000 tons).

Drawing

The term drawing, when it applies to the manufacture of tube,
rod, bar, or wire, refers to the pulling of metal through a die
or succession of dies to reduce its diameter, alter the cross
sectional shape, or increase its hardness.  In the drawing of
aluminum tubing, one end of the extruded tube is swaged to form a
solid point and then passed through the die.  A clamp, known as a
bogie, grips the swaged end of tubing, as shown in Figure III-9.
A mandrel is then inserted into the die orifice, and the tubing
is pulled between the mandrel and die, reducing the outside diam-
eter and the wall thickness of the tubing.  Wire, rod, and bar
drawing is accomplished in a similar manner, but the aluminum is
drawn through a simple die orifice without using a mandrel.

In order to ensure uniform drawing temperatures and avoid exces-
sive wear on the dies and mandrels used, it is essential that a
suitable lubricant be applied during drawing.  A wide variety of
lubricants are used for this purpose.  Heavier draws, which have
a higher reduction in diameter, may require oil-based lubricants,
but oil-in-water emulsions are used for many applications.  Soap
solutions may also be used for some of the lighter draws.  Draw-
ing oils are usually recycled until their lubricating properties
are exhausted.

Intermediate annealing is frequently required between draws in
order to restore the ductility lost by cold working of the drawn
product.  Degreasing of the aluminum may be required to prevent
burning of heavy lubricating oils in the annealing furnaces.

Of the plants surveyed, 77 are involved in the drawing of tube,
wire, rod, and bar.  The geographical location of these plants is
shown in Figure 111-10.  No aluminum forming wastewater is dis-
charged at 51 of the plants.  Of the remainder, 10 discharge
directly to surface water, and 16 discharge indirectly to a POTW.
The production distribution is summarized as follows:  of the 57
drawing operations for which 1977 production data were available,
46 percent produced less than 900 kkg (1,000 tons) of aluminum
and aluminum alloys; 74 percent produced less than 4,500 kkg
(5,000 tons); and 82 percent produced less than 9,000 kkg
(10,000 tons).

Sawing.  Sawing may be required for a number of aluminum forming
processes.  Before ingots can be used as stock for rolling or
extrusion, the ingot may require scalping or sawing to a suitable
length.  Following processes such as rolling, extrusion, and
drawing, the aluminum products may be sawed.  The circular saws
                               93

-------
and band saws used generally require  a  cutting  lubricant  in  order
to minimize friction and act as a coolant.  Oil-in-water  emul-
sions or mineral-based oils are usually applied to  the  sides  of
the blade as a spray.  In some cases, a heavy grease or wax  may
be used as a saw lubricant.  Normally,  saw  oils are not dis-
charged as a wastewater stream.  The  lubricants frequently are
carried over on the product or removed  together with the  saw
chips for reprocessing.  In some cases; however, recycle  and  dis-
charge of a low-volume saw lubricant  stream is  practiced,

Swaging.  Swaging is a forming operation  frequently associated
with drawing.  Swaging is often the initial step in drawing  tube
or wire.  By repeated blows of one or more  pairs of opposing
dies, a solid point is formed.  The point is then inserted
through the drawing die and gripped.  In  a  few  cases, swaging is
used in tube forming without a subsequent drawing operation.
Some lubricants, such as waxes and kerosene, may be used  to
prevent adhesion of the metal or oxide  on the swaging dies.

ANCILLARY OPERATIONS

Casting

Before aluminum alloys can be used for  rolling  or extrusion,  and
subsequently for other aluminum forming operations, they  are  usu-
ally cast into ingots of suitable size  and  shape.   Although
ingots may be prepared at smelters or other forming plants, 85 of
the 277 plants surveyed indicated that  casting  is done on site.
In addition, 30 of the 31 primary aluminum plants surveyed in the
nonferrous metals study indicated that  some form of casting  is
done on site.  Nine of these plants fall  into both  the  aluminum
forming and nonferrous metals categories.  Therefore, 106 primary
reduction and aluminum forming plants have  casting  operations on
site.

The equipment and methods of casting  used at aluminum forming
plants are the same as those employed by  primary plants plus  the
water requirements and waste characteristics are also very simi-
lar.  Casting done at a plant which does both primary aluminum
reduction and aluminum forming will be  subject  to the casting
limitations for primary aluminum if they  cast the aluminum
directly without cooling.  If the aluminum  is a remelted  primary
aluminum product then the casting subsequent to the remelting
will be subject to the aluminum forming limitations.

The aluminum alloys used as the raw materials for casting opera-
tions are sometimes purchased from nearby smelters  and  trans-
ported to the forming plants in the molten  state.   Usually, how-
ever, purchased aluminum ingots are charged together with alloy-
ing elements into melting furnaces at the casting plants.

-------
Several types of furnaces can be used, but reverberatory furnaces
are the most common.  The melting temperatures used range from
650 to 750°C.

At many plants, fluxes are added to the metal in order to reduce
hydrogen contamination, remove oxides, and eliminate undesirable
trace elements.  Solid fluxes, such as hexachloroethane, aluminum
chloride, and anhydrous magnesium chloride, may be used, but it
is more common to bubble gases such as chlorine, nitrogen, argon,
helium, and mixtures of chlorine and inert gases through the
molten metal.  Fluxing is accomplished by inserting a long,
perforated "lance" into the molten liquid and pumping the gas
through it.  This forces the oxides of aluminum back up to the
surface.  The oxides form on top of the metal while it stands in
the crucibles and after it is poured into the furnace, and--being
heavier than pure aluminum—sink down into the molten metal.
Bubbles in the fluxing material surround the aluminum oxide and
carry it up to the surface, where it can be skimmed off with big,
long-handled rakes.

After alloying and fluxing, the metal is allowed to flow into a
second or  holding" compartment of the furnace, which acts as a
reservoir.  When the reservoir of molten metal is sufficiently
full the metal may be drawn off to be cast.

Certain complex reactions occur in the furnace itself and, as a
result, some hydrogen gas is trapped in the molten metal.  So,
just before it moves from the charging furnace to the holding
furnaces, the metal is "degassed" by introducing a combination of
nitrogen and chlorine gas, or chlorine gas alone, or other chemi-
cals.  Although similar to fluxing in its description, degassing
has an entirely different purpose but both may occur in the same
operation.

The fluxing and degassing operations are not the same as the
demagging process used in the manufacture of secondary aluminum.
Like degassing and fluxing, demagging involves bubbling of chlo-
rine gas through molten aluminum, however the constituent to be
removed through demagging is primarily magnesium.  Thus, the
demagging process is a refining process which frequently requires
significantly more chlorine than degassing or fluxing and some
type of wet air pollution control.

One of the problems associated with furnace degassing with
chlorine is the need for air pollution control.  If the alloy
being treated does not contain magnesium, the chlorine gas will
react to form aluminum chloride, which exists as a dense, white
smoke.  The presence of hydrochloric acid in these vapors
necessitates the use of wet scrubbers.  For this reason, other
gases or mixtures of gases may be preferred as degassing agents.
In addition, a number of in-line treatment methods that eliminate
                               95

-------
the need for fluxing when degassing aluminum have recently been
developed and are being adopted by the industry.  For a more
detailed description of these alternatives, see Section VII.  One
of the aluminum forming plants and four primary aluminum plants
with casting operations reported using wet air pollution controls
to treat fumes from their melting furnaces.  Chlorine was
occasionally cited as a degassing agent.

The casting methods used in aluminum forming can be divided into
three classes:

        Direct chill casting,
        Continuous casting, and
        Stationary casting.

The process variations among these techniques affect both the
metallic properties of the aluminum that is cast and the
characteristics of associated wastewater streams.

Direct Chill Casting.  Direct chill casting is performed at 61
aluminum forming plants and is the most widely used method of
casting aluminum for subsequent forming.  Direct chill casting is
characterized by continuous solidification of the metal while it
is being poured.  The length of an ingot cast using this method
is determined by the vertical distance it is allowed to drop
rather than by mold dimensions.

As shown in Figure III-ll , molten aluminum is tapped from the
melting furnace and flows through a distributor channel into a
shallow mold.  Noncontact cooling water circulates within this
mold, causing solidification of the aluminum.  The base of the
mold is attached to a hydraulic cylinder which is gradually
lowered as pouring continues.  As the solidified aluminum leaves
the mold, it is sprayed with contact cooling water to reduce the
temperature of the forming ingot.  The cylinder continues to
descend into a tank of water, causing further cooling of the
ingot as it is immersed.  When the cylinder has reached its
lowest position, pouring stops and the ingot is lifted from the
pit.  The hydraulic cylinder is then raised and positioned for
another casting cycle.

In direct chill casting, lubrication of the mold is required to
ensure proper ingot quality.  Lard or castor oil is usually
applied before casting begins and may be reapplied during the
drop.  Much of the lubricant volatilizes on contact with the
molten aluminum, but contamination of the contact cooling water
with oil and oil residues does occur.

The production distribution is summarized as follows:  of the 56
direct chill casting operations for which 1977 production data
were available, 52 percent produced less than 23,000 kkg (25,000
                               96

-------
tons) of aluminum and aluminum alloys; 73 percent produced less
than 45,000 kkg (50,000 tons); and 89 percent produced less than
180,000 kkg (200,000 tons).  Direct chill casting is also per-
formed by 27 primary aluminum plants covered in the nonferrous
metals survey.  A comparison of production information was made
using production capacity from the two data sets, since the pri-
mary aluminum data was not from 1977.  Of the 18 reduction plants
supplying production capacity data, 28 percent produce less than
90,000 kkg (100,000 tons); 78 percent produce less than 180,000
kkg  (200,000 tons); and 94 percent produce less than 227,000 kkg
(250,000 tons).

Continuous Casting.  Of the aluminum forming category plants sur-
veyed, 15 use continuous casting instead of, or in addition to,
direct chill casting methods.  Unlike direct chill casting, no
restrictions are placed on the length of the casting, and it is
not  necessary to interrupt production to remove the cast product.
The use of continuous casting eliminates or reduces the degree of
subsequent rolling required.

A relatively new technology, continuous casting of aluminum first
came into practice in the late 1950fs.  Since then, improvements
and  modifications have resulted in the increased use of this pro-
cess.  Current applications include the casting of plate, sheet,
foil, and rod.  Because continuous casting affects the mechanical
properties of the aluminum cast, the use of continuous casting is
limited by the alloys used, the nature of subsequent forming
operations, and the desired properties of the finished product.
In applications where continuous casting can be used, the follow-
ing  advantages have been cited:

        Increased flexibility in the dimensions of the cast
        product;

        Low capital costs, as little as 10 to 15 percent of the
        cost of conventional direct chill casting and hot rolling
        methods; and

        Low energy requirements, reducing the amount of energy
        required to produce comparable products by direct chill
        casting and rolling methods by 35 to 80 percent, depend-
        ing on the product being cast.

In addition, the use of continuous casting techniques has been
found to significantly reduce or eliminate the use of contact
cooling water and oil lubricants.

A number of different continuous casting processes are currently
being used in the industry.  Although the methods vary somewhat,
they are similar in principle to one of the three processes dia-
grammed schematically in Figure 111-12.  The most common method
                               97

-------
of continuous sheet casting, shown in Figure 1II-12A, substitutes
a single casting process for the conventional direct chill cast-
ing, scalping, heating, and hot rolling sequence.  The typical
continuous sheet casting line consists of melting and holding
furnaces, a caster, pinch roll, shear, bridle, and coiler.
Molten aluminum flows from the holding furnace through a degas-
sing chamber or filter to the caster headbox.  The level of
molten aluminum maintained in the headbox causes the metal to
flow upwards through the top assembly, which distributes it
uniformly across the width of the casting rolls.  The aluminum
solidifies as it leaves the tip and is further cooled and solidi-
fied as it passes through the internally water-cooled rolls.  It
leaves the caster as a formed sheet and successively passes
through pinch rolls, a shear, and a tension bridle before being
wound into a coil.  The cooling water associated with this method
of continuous sheet casting never comes into contact with the
aluminum metal.

Another method of casting continuous aluminum sheet is shown in
Figure III-12B.  This process is not very common and is limited
due to the mechanical properties of the sheet produced.  Molten
aluminum is poured into a rotating perforated cylinder.  The
droplets formed are air cooled and solidify as they fall.  At '
this point, the pellets may either be removed for temporary stor-
age or charged directly to a preheated chamber, hot rolled into
sheet, and coiled.  This unique process design not only elimi-
nates the use of contact cooling water, but also results in con-
siderable reductions in the amount of noncontact cooling water
required in the production of sheet.

Several methods of wheel casting, similar to the one shown in
Figure III-12C, are currently being used to produce aluminum rod.
Typically, continuous rod is manufactured on an integrated cast-
ing and rolling line consisting of a wheel belt caster, pinch
roll, shear, rolling trains, and a coiler.  A ring mold is set
into the edge of the casting wheel.  The mold is bound peripher-
ally by a continuous belt which loops around the casting wheel
and an associated idler wheel.  As the casting wheel rotates,
aluminum is poured into the mold and solidifies.  After a rota-
tion of approximately 180°, the belt separates from the mold,
releasing the still pliable aluminum bar.  The bar then enters
directly into an in-line rolling mill, where it is rolled into
rod and coiled.  Noncontact cooling water circulating within the
casting wheel is used to control the temperature of the ring
mold.  Cooling of the belt is, for the most part, also accom-
plished by noncontact water, though some plants indicated that
contact with the aluminum bar as it leaves the mold is difficult
to avoid.  Some models are actually designed so that cooling
water circulates within the interior of the wheel and then flows
over the freshly cast bar and onto the belt as the belt separates
from the ring mold.  Because continuous casting incorporates
                               98

-------
casting and rolling into a single process, rolling lubricants may
be required.  Frequently, oil emulsions similar to those used in
conventional hot rolling are used for this purpose.  Graphite
solutions may be suitable for roll lubrication of some continuous
casting processes.  In other instances, aqueous solutions of
magnesia are used.

The production distribution is summarized as follows:  of the 14
continuous casting operations for which 1977 production data were
available, 57 percent produced less than 18,000 kkg  (20,000 tons)
of aluminum and aluminum alloys; 71 percent produced less than
27,000 kkg (30,000 tons); and 100 percent produced less than
36,000 kkg (40,000 tons).  Five plants in the primary aluminum
industry have continuous casting.  Production was compared using
the production capacity rather than actual production since 1977
production was not available.  Of the four plants supplying pro-
duction capacity data, one plant has a capacity less than 22,700
kkg (25,000 tons); two plants have a capacity of 45,000 kkg
(50,000 tons) or less; and no plant has a capacity above 68,000
kkg (75,000 tons).

Stationary Casting.  Stationary casting of aluminum ingots is
practiced at 16 aluminum plants, usually to recycle  in-house
aluminum scrap.  The production distribution is summarized as
follows:  of the 10 stationary 'casting operations for which 1977
production data were available, 50 percent produced  less than
1,800 kkg (2,000 tons) of aluminum and aluminum alloys; 70 per-
cent produced less than 4,500 kkg (5,000 tons); and 90 percent
produced less than 9,000 kkg (10,000 tons).  In the  stationary
casting method, molten aluminum is poured into cast  iron molds
and allowed to air cool.  Lubricants and cooling water are not
required.  Melting and casting procedures are dictated by the
intended use of the ingots produced.  Frequently, the ingots are
used as raw material for subsequent aluminum forming operations
at the plant.  Other plants sell these ingots for reprocessing.

Heat Treatment

Heat treatment is an integral part of aluminum forming practiced
at nearly every plant in the category.  It is frequently used
both in process and as a final step in forming to give the
aluminum alloy the desired mechanical properties.  The general
types of heat treatment applied are the following:

     -  Homogenizing, to increase the workability and help con-
        trol recrystallization and grain growth following
        casting;

        Annealing, to soften work-hardened and heatrtreated
        alloys, relieve stress, and stabilize properties and
        dimensions;
                                99

-------
        Solution heat treatment, to improve mechanical properties
        by maximizing the concentration of hardening constituents
        in solid solution; and

        Artificial aging, to provide hardening by precipitation
        of constituents from solid solution.

Homogenizing, annealing, and aging are dry processes, while solu-
tion heat treatment typically involves significant quantities of
contact cooling water.

In the casting process, large crystals of intermetallic compounds
are distributed heterogeneously throughout the ingot.  Homogeni-
zation of the cast ingot provides a more uniform distribution of
the soluble constituents within the alloy.  By reducing the brit-
tleness caused by casting, homogenization prepares the ingot for
subsequent forming operations.  The need for homogenization and
the time and temperatures required are dependent on the alloy
involved, the ingot size, the method of casting used, and the
nature of the subsequent forming operations.  Typically, the
ingot is heated to a temperature ranging between 425 and 650°C
and held at that temperature for four to 48 hours.  The ingots
are then allowed to air cool.  One plant does use a water mist to
aid final cooling after homogenizing.

Annealing is used by plants in the aluminum forming category to
remove the effects of strain hardening or solution heat treat-
ment.  The alloy is raised to its recrystallization temperature,
typically between 350 and 400°C.  Nonheat-treatable, strain-
hardened alloys need only be held in the furnace until the
annealing temperature is reached; heat-treatable alloys usually
require a detention time of two or three hours.  In continuous
furnaces, the metal is raised to higher temperatures (i,e., 425
to 450°C) and detained in the furnace for 30 to 60 seconds.  Once
removed from the annealing furnace, it is essential that the
heat-treatable alloys be cooled to 250°C or lower at a slow, con-
trolled rate.  After annealing, the aluminum is in a ductile,
more workable condition suitable for subsequent forming opera-
tions.  One plant reported that a water seal was used on its
annealing furnace to maintain the inert atmosphere in the anneal-
ing furnace.  Water circulates through a fibrous material which
provides the seal between the furnace door and the frame.  The
purpose of the water is to prevent scorching of the seal mate-
rial.  Some of the water does pass through the fibrous material
and contacts the metal; however, this water evaporates on
contact.  After discussions with the plant and the furnace
vendor, it was concluded that the furnace seal water is a non-
contact cooling water stream.

Solution heat treatment is accomplished by raising the tempera-
ture of a heat-treatable alloy to the eutectic temperature, where
                               100

-------
it is held for the required length of time and quenched rapidly.
As a result of this process, the metallic constituents in the
alloy are held in a super-saturated solid solution, improving its
mechanical properties.  The metal temperatures recommended for
solution heat treatment of formed aluminum alloys typically range
from 450 to 550 C.  The required length of time the metal must be
held at this temperature varies from one to 48 hours.  In the
case of extrusion, certain aluminum alloys can be solution heat
treated immediately following the extrusion process.  In this
procedure, known as press heat treatment, the metal is extruded
at the required temperatures and quenched with contact cooling
water as it emerges from the die or press.

The quenching techniques used in solution heat treatment are
frequently critical in achieving the desired mechanical proper-
ties.  The sensitivity of alloys to quenching varies, but delays
in transferring the product from the furnace to the quench, a
quenching rate that is incorrect or not uniform, and the quality
of the quenching medium used can all have serious detrimental
effects.  With few exceptions, contact cooling water is used to
quench solution heat treated products.  Immersion-quenching in
contact cooling water, typically ranging from 65 to 100°C, is
used for most aluminum formed products.  Forgings can be quenched
at cooler temperatures (i.e., 60 to 70°C).  Spray or flush
quenching is sometimes used to quench thick products.  Solution
heat treated forgings of certain alloys can be quenched using an
air blast rather than a water medium.  Air quenching can also be
used for certain extrusions following press heat treatment.
Immersion quenching using glycol is often found in  the manufac-
ture of high-performance aeronautical components.  This unusual
operation is critical for achieving desired mechanical proper-
ties, and its use may increase as the demand for high-quality
parts goes up.

Artificial aging, also known as precipitation heat  treatment, is
applied to some aluminum alloys in order to cause precipitation
of super-saturated constituents in the metal.  The  alloy is
heated to a relatively low temperature (i.e., 120 to 200°C) for
several hours and then air cooled.  Artificial aging is fre-
quently used following solution heat treatment to develop the
maximum hardness and ultimate tensile and yield strength in the
metal.  For certain alloys, the mechanical properties are maxi-
mized by sequentially applying solution heat treatment, cold
working, and artificial aging.

At elevated temperatures, the presence of water vapors can dis-
rupt the oxide film on the surface of the product,  especially i£
the atmosphere is also contaminated with ammonia or sulfur com-
pounds.  Possible detrimental effects include surface blistering,
porosity, discoloration, and a decrease in tensile  properties.
When this occurs, it is necessary to control the atmosphere
                               101

-------
within a heat treatment furnace.  A number of techniques can be
used to control the atmosphere.  At some aluminum forming plants,
natural gas is burned to generate an inert atmosphere.  The
resulting flue gases are cooled to remove moisture and are intro-
duced to the heat treatment furnace.  Under the proper condi-
tions, the same fuel that heats the furnace can be used for this
     * i
purpose.  Because of the high sulfur content in most furnace
fuels; however, the off-gases require treatment by wet scrubbers
before they can be used as inert atmosphere for heat treatment.

Cleaning and Etching

A number of chemical or electrochemical treatments may be applied
after the forming of aluminum or aluminum alloy products.  Sol-
vent, acid and alkaline solutions, and detergents can be used to
clean soils such as oil and grease from the aluminum surface.
Acid and alkaline solutions can also be used to etch the product
or brighten its surface.  Deoxidizing and desmutting are accom-
plished with acid solutions.  Surface treatments and their asso-
ciated rinses are usually combined in a single line of successive
tanks.  Wastewater discharge from these lines is typically com-
mingled prior to treatment or discharge.  In some cases, rinse
water from one treatment is reused in the rinse of another.
These treatments may be used for cleaning purposes or to provide
the desired finish for an aluminum formed product, or they may
simply prepare the aluminum surface for subsequent coating by
such processes as anodizing, conversion coating, electroplating,
painting, and porcelain enameling.  A number of different terms
are commonly used in referring to sequences of surface treatments
(e.g., pickling lines, cleaning lines, etch lines, preparation
lines, and pretreatment lines).  The terminology depends, to some
degree,  on the purpose of the lines, but usage varies within the
industry.  In addition, the characteristics of wastewater gener-
ated by surface treatment is determined by the unit components of
the treatment lines rather than the specific purpose of its
application.  In order to simplify discussion, the term cleaning
or etching is used in this document to refer to any surface
treatment processes other than solvent cleaning.

Surface treatment operations performed as an integral part of the
forming process are considered to be within the scope of the
aluminum forming category.  In other words, those surface treat-
ment operations that immediately follow an aluminum forming
operation or precede further forming or working of the aluminum
are considered a part of aluminum forming.

In situations where surface treatment operations are an integral
part of coil coating lines or are not an integral part of the
forming process, (i.e., performed at another site) the waste-
waters will not be considered as aluminum forming wastewaters.
                               102

-------
Solvent Cleaning.  Solvent cleaners are used to remove oil and
grease compounds from the surface of aluminum products.  This
process is usually used to remove cold rolling and drawing
lubricants before products are annealed, finished, or shipped.
There are three basic methods of solvent cleaning:  vapor
degreasing, cold cleaning, and emulsified solvent degreasing.

Vapor degreasing, the predominant method of solvent cleaning in
the aluminum forming industry, uses the hot vapors of chlorinated
solvents to remove oils, greases, and waxes.  In simplest form,
vapor degreasing units consist of an open steel tank similar to
the one shown in Figure III-13A.  Solvent is heated at the bottom
of a steel tank and, as it boils, a hot solvent vapor is gener-
ated.  Because of its higher density, the vapor displaces air and
fills the tank.  Near the top of the tank, condenser coils
provide a cooling zone in which the vapors condense and are
prevented from rising above a fixed level.  When cool aluminum
forming products are lowered into the hot vapor, the solvent con-
denses onto the product, dissolving oils present on the surface.
Vapor degreasing units may also incorporate immersion or spraying
of the hot solvent for more effective cleaning.  Conveyor systems
similar to the one shown in Figure III-13B are used in some
applications.

The solvents most commonly used for vapor degreasing in aluminum
forming are trichloroethylene, 1,1,1-trichloroethane, and per-
chloroethylene.  Selection of the solvent depends on a number of
factors, including solvent boiling point, product dimension, and
alloy makeup; and the nature of the oil, grease, or wax to be
removed.  Stabilizing agents are usually added to the solvents.

Vapor degreasing solvents are frequently recovered by distilla-
tion.  Solvents can be distilled either within the degreasing
unit itself or in a solvent recovery still.  The sludge residue
generated in the recovery process is toxic and may be flammable.
Suitable handling and disposal procedures must be followed and
are discussed in subsequent sections of this report (principally
in Section VII).

Cold cleaning is another solvent cleaning method and involves
hand wiping, spraying, or immersion of metal parts in organic
solvents to remove oil, grease, and other contaminants from the
surface.  A variety of solvents or solvent blends, primarily
petroleums and chlorinated hydrocarbons, are used in cold clean-
ing.  These solvents can be reclaimed by distillation either on
site or by an outside recovery service.  For highly contaminated
solvents; however, reclamation may not be cost effective, and
contract hauling is the disposal method of choice.  In general,
cold cleaning is not as effective as vapor degreasing treatment,
but the costs are considerably lower.
                               103

-------
Emuls ifled solvents can also be used to clean aluminum, but they
are less efficient than pure solvents, and their use is limited
to the removal of light oil and grease.  Reclamation of emulsi-
fied solvents is not economically feasible at this time.
Contract hauling of the spent solvents is the disposal method
practiced by plants in the aluminum forming category.

Due to the toxic nature of many cleaning solvents, emission con-
trols may be required.

Alkaline and Acid Cleaning.  Alkaline cleaning is the most common
method of cleaning aluminum surfaces.  The alkaline solutions
vary in pH and chemical composition.  Inhibitors are frequently
added to minimize or prevent attack on the metal.  Alkaline
cleaners are able to emulsify vegetable and animal oils and
greases to a certain degree and are effective in the removal of
lard, oil, and other such compounds.  Mineral oils and grease, on
the other hand, are not emulsified by alkaline cleaning solutions
and, therefore, are not removed as effectively.

Aluminum products can be cleaned with an alkaline solution either
by immersion or spray.  The solution is usually maintained at a
temperature ranging between 60 and 80°C.  Rinsing, usually with
warm water, should follow the alkaline cleaning process to
prevent the solution from drying on the product.

Acid solutions can also be used for aluminum cleaning, but they
are less effective than either alkaline or solvent cleaning sys-
tems.  Their use is generally limited to the removal of oxides
and smut.  Acid cleaning solutions usually have a pH ranging from
4.0 to 5.7 and temperatures between room temperature and 80 C.
The solutions typically contain one or two acids  (e.g., nitric,
sulfuric, phosphoric, chromic, and hydrofluoric acids).

Chemical and Electrochemical Brightening.  The surface of alumi-
num or aluminum alloys can be chemically or electrochemically
brightened to improve surface smoothness and reflectance.  Chemi-
cal brightening is accomplished by immersing the product in baths
of concentrated or dilute acid solutions.  The acids most com-
monly used for this purpose are sulfuric; nitric; phosphoric;
acetic; and, to a lesser extent, chromic and hydrofluoric.  Other
constituents, such as copper or lead salts, glycerol, and
ethylene glycol, may be added as well.

Aluminum can also be brightened by electrochemical methods.  The
product is immersed in an electrolyte bath, through which direct
current is passed.  The electrolytic solutions are acidic, con-
taining hydrofluoric, phosphoric, chromic, or sulfuric acid, or
they may be alkaline, containing sodium carbonate or trisodium
phosphate.
                               104

-------
Etching.  Chemical etchants are used to reduce or eliminate
scratches and other surface imperfections, to remove oxides, or
to provide surface roughness.  The most widely used etchant is an
aqueous solution of sodium hydroxide.  The concentration and tem-
perature of the caustic bath are carefully controlled to provide
the desired degree of etching.  In general, the sodium hydroxide
concentration ranges from 1 to 15 percent, and the solution is
maintained between 50 and 80°C.  It is important that products
are rinsed immediately following caustic etching.

As a result of etching with a caustic solution, the surface of
the product may be discolored.  Alloying constituents, such as
copper, manganese, and silicon, as well as other impurities in
the metal, are not dissolved in the etchant and form a dark
residual film referred to as smut.  In order to alleviate this
problem, caustic etching is frequently followed by destautting.

For specific aluminum alloys or desired finishes, acid etching
may be used.  Aluminum-silicon alloys are  frequently etched in a
solution containing nitric and hydrofluoric acids.  Fumes
generated by acid etching are corrosive and may constitute a
health hazard requiring suitable air pollution control.  In
general, etching with acids is more expensive, but it may result
in less aluminum loss, which can be an economic advantage.

Desmutting and Deoxidizing.  Acid solutions are used in desmut-
ting and deoxidizing aluminum products.  Desmutting, a process
frequently applied following caustic etching, is accomplished by
immersion in an acid solution that dissolves the residual film.
Although a number of acid solutions can be used to remove smut,
dilute nitric acid is most commonly employed.

Deoxidizers are acid solutions formulated  to remove specific
oxide films and coatings from the aluminum products.  The oxides
may have been formed naturally, or they may result from heat
treatment or other surface treatments.  Deoxidizing solutions can
be composed of a variety of acids, including chromic, phosphoric,
sulfuric, nitric, and hydrofluoric acid.

Anodizing.  Anodizing is either a chemical or an electrolytic
oxidation process which converts the surface of the metal to an
insoluble oxide.  These oxide coatings provide corrosion protec-
tion, decorative surfaces, a base for painting and other coating
processes, as well as special electrical and mechanical proper-
ties.

The majority of anodizing is carried out by immersion of racked
parts in tanks.  Continuous anodizing may be done on large coils
of aluminum in a manner similar to continuous electroplating.
The formation of the oxide occurs (in electrolytic anodizing)
when the parts are made anodic in dilute sulfuric acid or dilute
                               105

-------
chromic acid solutions.  The oxide layer begins formation at the
extreme outer surface, and as the reaction proceeds, the oxide
grows into the metal.  The last formed oxide, known as the bound-
ary layer, is located at the interface between the aluminum and
the oxide.  The boundary is extremely thin and nonporous.  The
sulfuric acid process is typically used for all parts subject to
stress or containing recesses in which the sulfuric acid solution
may be retained and attack the aluminum.  Chromic acid anodic
coatings are more protective than sulfuric acid coatings and have
a relatively thick boundary layer.  For these reasons, a chromic
acid bath is used if a complete rinsing of the part cannot be
achieved.

Chemical Conversion Coating.  This manufacturing operation
includes chromating, phosphating, and passivating.  These coat-
ings are applied to previously deposited metal or basis material
for increased corrosion protection, lubricity, preparation of the
surface for additional coatings, or formulation of a special
surface appearance.  In chromating, a portion of the aluminum is
converted to one of the components of the protective film formed
by the coating solution.  This occurs by reaction with aqueous
solutions containing hexavalent chromium and active organic or
inorganic compounds.  Most of the coatings are applied by
chemical immersion, although a spray or brush treatment can be
used.

Phosphate coatings are used to provide a good base for paints and
other organic coatings, to condition the surfaces for cold form-
ing operations by providing a base for drawing compounds and
lubricants, and to impart corrosion resistance to the aluminum
surface by the coating itself or by providing a suitable base for
rust-preventive oils or waxes.  Phosphate conversion coatings are
formed by the immersion of aluminum in a dilute solution of phos-
phoric acid.  The method of applying the phosphate coating is
dependent upon the size and shape of the part to be coated.
Small parts frequently are coated in barrels immersed in the
phosphating solution.  Large parts may be spray coated or
continuously passed through the phosphating solution.

                            SECTION IV

                    INDUSTRY SUBCATEGORIZATION
Subcategorization should take Into account pertinent industry
characteristics, manufacturing process variations, wastewater
characteristics, and other factors.  Effluent limitations and
standards establish mass limitations on the discharge of pollu-
tants which are applied, through the permit issuance process, to
specific dischargers.  To allow the national standard to be
applied to a wide range of sizes of production units, the mass of
pollutant discharge must be referenced to a unit of production.
This factor is referred to as a production normalizing parameter
and is developed in conjunction with subcategorization.

Division of the category into subcategories provides a mechanism
for addressing process and product variations which result in
distinct wastewater characteristics.  The selection of production
normalizing parameters provides the means for compensating for
differences in production rates among plants with similar
products and processes within a uniform set of mass-based
effluent limitations and standards.

SUBCATEGORIZATION BASIS

Factors Considered

After considering the nature of the various segments of the
aluminum forming industry and their operations, EPA evaluated
possible bases for subcategorization.  These include:

      1.  Raw Materials Used
      2.  Manufacturing Processes
      3.  Wastewater Characteristics
      4.  Products Manufactured
      5.  Water Use
      6.  Water Pollution Control Technology
      7.  Treatment Costs
      8.  Solid Waste Generation and Disposal
      9.  Size of Plant
     10.  Age of Plant
     11.  Number of Employees
     12.  Total Energy Requirements (Manufacturing Process and
          Water Treatment and Control)
     13.  Non-Water Quality Characteristics
     14.  Unique Plant Characteristics
                               123

-------
In addition to considering how the individual  factors  influenced
subcategorization, the interrelationship between different
factors was also evaluated.

After considering the above factors, it was concluded  that the
aluminum forming category is comprised of separate and distinct
processes with enough variability in products  and wastes to
require the division of the industry into a number of  discrete
subcategories.  The individual processes, wastewater characteris-
tics, and treatment effectiveness comprise the most significant
factors in the subcategorization of this complex industry.  The
remaining factors either served to support and substantiate the
subcategorization or were shown to be inappropriate bases for
subcategorization.  Discussion of each of the  factors  is pre-
sented later in this section.

Effluent limitations and standards establishing mass limitations
on the discharge of pollutants are applied to  direct dischargers
through the permit issuance process and to indirect dischargers
by POTW.  The mass limitations are normalized  to some  factor of
production to avoid the possibility of plants  meeting  the
limitations by dilution rather than treatment.  The production
normalizing parameter (PNP) allows for equitable consideration of
all plants, regardless of size or volume of production, because
we assume that the mass of pollutants discharged in the raw
wastewater is dependent on the production processes that generate
the wastewater.  Thus, the wastewater from a given process will
have similar characteristics from plant to plant with  a constant
mass of pollutant generated per an appropriate unit of
production.

To establish effluent limitations that relate  the mass of pollu-
tants discharged to production within the above subcategories,
appropriate PNP's had to be selected.  In this analysis, the
following alternatives were considered:

     1.   mass of aluminum processed
     2.   number of products processed
     3.   area of aluminum processed
     4.   mass of process chemicals used

The evaluation of alternative PNP's, discussed further in this
section, involved consideration of the same factors used in
analyzing subcategorization.

Subcatesorization Factors Considered

Each of the factors considered in developing subcategorization is
discussed below.   In evaluating these factors, the following
items were addressed:   the nature of subcategorization based on
                                124

-------
the factor being considered; the positive and negative aspects of
the potential subcategorization; and the potential PNP' s that
could be used in conjunction with this subcategorization scheme.

Raw Materials.  The raw materials used in the aluminum forming
category can be classified as follows:

        aluminum and aluminum alloys;

        lubricants;

        surface treatment, degreasing, and furnace fluxing
        chemicals; and

        additives to lubricants and cooling water.

At times, the same raw material may take on various effluent
characteristics, and these will require different treatment.  For
example, an oil that is emulsified requires different treatment
than the same oil in a pure state.  Due to process variations and
the proprietary nature of many chemical additives, it is diffi-
cult to establish a production normalizing parameter that
directly relates pollutant discharge to specific process chemi-
cals or lubricants,

Manufacturing Processes.  There are four principal manufacturing
processes used in aluminum forming:  rolling, extrusion, forging,
and drawing.   Since the terminology is common in the aluminum
forming industry, subcategorization using these four processes
would be easily recognized and understood.

Typically,  a company will have only one of these forming opera-
tions at an individual plant site, as tabulated below.  Conse-
quently, all the plant operations associated with that facility
would be regulated under one subcategory.

-------
Subcategorization based on the principal manufacturing processes
does not take into account the wastewater generated by minor or
ancillary production processes.  In many cases, the principal
manufacturing process will contribute only a small fraction of
the plant's total process wastewater.

Wastewater Characteristics and Treatment Technologies.  Using
wastewater characteristics as a criterion, the following sub-
categorization would result:  emulsions; pure oils, also known as
neat oils; oil-in water (nonemulsified) mixtures; and acidic or
basic wastewaters.  The major types of unit operations producing
the identified waste streams are listed below.

This Subcategorization scheme reflects the fact that effective
wastewater pollutant removal is dependent on the wastewater
characteristics and treatment system designed for removal of
these pollutants.  Treatment of emulsified and oil-in-water  (non-
emulsified) wastewaters in the same treatment system is inappro-
priate because additional treatment steps are required to break
emulsions.  Wastewaters generated during the cleaning or etching
of aluminum with an acid or base solution may require pH adjust-
ment with metals removal and may not need to be treated for oil
removal.  Finally, since spent neat oils are pure oil and contain
no water, they may frequently be disposed of by incineration or
contract hauling, thus requiring no treatment.

Products Manufactured.  Another approach to Subcategorization is
based on the products manufactured, as listed below:

The product manufactured is an excellent criterion  for  subcate-
gorization if the waste characterization and production process
to produce a given item are the same  from plant to  plant; how-
ever, this approach is not applicable to the manufacture of  many
aluminum formed products.  For example, rods can be produced by
two different production processes which generate similar waste-
water (i.e., rolling and drawing), the mass of pollutants gener-
ated per unit of rod produced by rolling will be different than
the amount generated by drawing the rod.  Furthermore,  some
products produced by the same process may use different lubri-
cants, therefore generating a waste with different  characteris-
tics.  Strip and sheet, for example,  can be produced by opera-
tions which use either neat or emulsified oils as lubricants.

This approach to subcategorization does not take into account
ancillary operations, such as cleaning or etching,  heat treat-
ment, and casting, that may be found  at any given plant.  All of
these factors make it very difficult  to develop an  equitable
regulation using products manufactured as a basis for
subcategorization.

Process Water Use.  Major differences in water use  (volume of
water applied to a process per mass of product) between
facilities with large and small production could warrant the
development of subcategories.

As will be discussed in Section V, analysis of the  data indicated
that production normalized water use  (i.e., gallons per ton  of
aluminum formed) for a given unit operation is usually  indepen-
dent of production volume.  For example, a large direct chill
casting operation will use about the  same amount of water per ton
of ingot produced as an operation casting much less aluminum by
the same method.  For certain unit operations, there is a trend
for the normalized water use to decrease with increased produc-
tion; however, no distinct break point could be identified to
distinguish between water use at high production and low produc-
tion plants.

-------
Size.  The number of employees and amount of aluminum processed
were used to measure relative sizes of aluminum forming plants.

Wastewaters produced by a production process are largely indepen-
dent of the number of plant employees.  Variations in staff occur
for many reasons, including shift differences, clerical and
administrative support, maintenance workers, efficiency of plant
operations, and market fluctuations.  Due to these and other
factors, the number of employees is constantly fluctuating, mak-
ing it difficult to develop a correlation between the number of
employees and wastewater generation.

Subcategorization based on size in terms of production of
aluminum would group plants by the off-pounds of extrusions,
sheets, rods, etc.  This is a good method of subcategorization
for an economic analysis on this category since plants producing
rod will compete for the same market, and smaller production
plants may have very different characteristics than large produc-
tion plants.  One drawback to this subcategorization approach is
that it does not account for the ancillary operations frequently
performed in conjunction with the forming operation.
	   Aluminum forming is one of the newest large-volume metal
industries.  The demand for aluminum products has grown greatly
since the end of World War II.  Thus, aluminum forming plants are
relatively modern; most are less than 30 years old.  Furthermore,
to remain competitive, plants must be constantly modernized.
Modernization of production equipment, processes, treatment sys-
tems , and air pollution control equipment is undertaken on a con-
tinuous basis throughout the industry.  Data regarding the age
and date of the latest major modification for each plant were
compiled from the dcp responses and summarized in Tables III-2
and I1I-3 (pp. 110  and 111 ), respectively.

Unique Plant Characteristics.  Aluminum forming plants are unique
on the basis of their physical locations and unit operations.
These unit operations are necessary to the manufacturing process,
but vary from plant to plant, depending on the product and
specifications.

Location.  The geographical distribution of the aluminum forming
plants is shown in Figure III-2 (p. 109).  The plants are not
limited to any one geographical location, but they are generally
located east of the Mississippi River, with pockets of plants
located in the western states of Washington, California, and
Texas.  Although some cost savings may be realized for facilities
located in nonurban settings where land is available to install
lagoons, equivalent control of wastewater pollutant discharge can
be achieved by urban plants with the use of physical and chemical
                                128

-------
treatment systems that have smaller land requirements.   Since
most plants are located in the eastern part of the United States
(an area where precipitation exceeds evaporation) or in urban
areas, evaporation and land application of the wastewater are not
commonly used.  Presently, only 27 of the 277 plants evaporate or
apply wastewater to land.

Included in this list are several operations that either do not
discharge a waste stream or discharge small quantities of pollu-
tants.  Furthermore, for subcategories based on these operations,
this approach to subcategorization does not take into account the
different types of oils used for lubrication.  For example, draw-
ing can use a neat oil lubricant or an emulsified oil lubricant.
Waste characteristics and treatment schemes are different for the
two types of oils used.

Subcategory Selection

In selecting the subcategories, the Agency tried to minimize the
number of subcategories, but at the same time provide sufficient
segmentation to account for the differences between processes and
associated wastewater streams.  Because the aluminum forming
category encompasses a variety of operations that generate
wastewaters with differing characteristics, it is necessary to
consider a combination of factors when establishing
subcategorization.

Each of the, factors listed and discussed previously are evaluated
below on the basis of suitability for subcategorizing the
aluminum forming category.

Raw Materials.  The pollutants in the wastewater discharged are
dependent on the raw materials; however, the amount of pollutants
discharged does not directly correlate with the nature of raw
materials used.  Discharge of heavy metals may result from the
presence of these compounds in the aluminum alloy; however, the
amount of metal that enters the wastewater is largely dependent
                                130

-------
on the operation performed on the alloy.  For  instance, etching
the workpiece will result in a higher metal discharge than roll-
ing the workpiece.  Subcategorization solely on the basis of raw
materials was considered inappropriate for this category because
of the difficulty associated with correlating  raw materials with
the discharge of pollutants.

Manufacturing Processes.  Aluminum forming is widely character-
ized by the principal manufacturing processes  of rolling, extrud-
ing, forging, and drawing.  The industry has built plants around
a single production process and is familiar with the terminology.
Pollutant generation can be related to the mass of production
from these processes.  On this basis, subcategorization based on
manufacturing processes is appropriate for this category; how-
ever, the four processes of rolling, extruding, forging, and
drawing do not account for the different lubricants, requiring
different treatments, that can be used for the rolling and
drawing operations.  This approach to subcategorization also
fails to consider the unique properties of the aluminum forming
plants in the variety of ancillary unit operations that may be
present, many of which generate large volumes  of wastewater.
Therefore, the manufacturing processes by themselves are not
suitable for subcategorizing the aluminum forming category.

Wastewater Characteristics.  Wastewater characteristics are very
important in the consideration of appropriate  treatment tech-
nology and form the basis for effluent limitations.  Subcategori-
zation based solely on wastewater characteristics is inappropri-
ate for the aluminum forming category since it is difficult to
develop a production normalizing parameter.  More than one
manufacturing process may generate a waste stream with the same
characteristics, such as rolling and drawing which both can use
neat oils and emulsions.  Volume of wastewater, or in this case
lubricant generated per the mass of aluminum rolled, may vary
greatly with the volume generated per mass of  aluminum drawn.
The purpose of subcategorizing is to allow for equitable regula-
tions across a category and the subcategories must allow for a
normalizing parameter to establish mass limitations.  Wastewater
characteristics alone are inappropriate for subcategorizing the
aluminum forming category.

Products Manufactured.  As discussed previously, the same product
can be manufactured by as many as three of the aluminum forming
operations.  The mass of pollutant generated per unit of product
will be different depending on the type of forming operation
employed.  Subcategorization based on products manufactured does
not account for the ancillary operations, such as cleaning or
etching, heat treatment, and casting, that may be found at any
given plant.  These factors make it very difficult to develop a
reliable effluent limitation using products manufactured as a
basis for the subcategorization.  Thus, this is an inappropriate
                               131

-------
approach for subcategorizing the aluminum  forming  category  to
establish equitable effluent limitations;  however,  subcategoriza-
tion on the basis of products manufactured is  an appropriate
approach for characterizing the industry for an economic  impact
analysis where the emphasis is on a plant's ability to  compete  in
the marketplace.

Process Water Use,  Process water use, when related to  the  mass
of aluminum processed, is fairly constant  regardless  of the pro-
duction volume.  Since no distinct differences in  water use could
be identified between plants with large production volumes  and
plants with small production volumes, the  Agency has  determined
that this approach is inappropriate to subcategorize  the  aluminum
forming category.  Flows which are normalized by some aspect of
production are used to establish effluent  limitations;  variations
in water use or discharge were considered  and  are  discussed in
detail in  Sections V and IX.

Size.  Size in terms of employment is considered to be  an
inappropriate basis for subcategorization  because  it  cannot be
directly related to the generation of wastewater.   Size in  terms
of production is also considered to be inappropriate  for  sub-
categorizing to establish effluent guidelines, since  it does not
account for the wastewaters generated by the ancillary
operations.

Age.  Since most aluminum forming plants have been built  in the
past 30 years and have been modernized frequently,  age  is not a
valid basis for subcategorization.

Location.  Location does not appear to be  a significant factor  on
which to base subcategorization.  Most aluminum forming plants
are located in urban areas ; thus, there is no vast disparity in
land availability between urban and rural  plants.   In addition,
few plants use land application or evaporation to  treat aluminum
forming wastewaters.

Unit Operations.  The principal benefit from using unit opera-
tions as a basis for subcategorization is  that an  appropriate
effluent limitation can be established for each waste stream
generated.  For each regulated pollutant,  a specific  pollutant
mass discharge value could be calculated for each  waste stream
present at the facility.  These values would be summed  to
determine the total mass discharge allowed for that pollutant at
that facility.

The difficulties with this approach are the large  number  of sub-
categories (approximately 25) and the need for a separate pro-
duction normalizing parameter for each subcategory or unit
operation.
                                132

-------
Primarily because of the large number of subcategories and  com-
plications associated with it, subcategorization based on unit
operations alone was not considered to be appropriate.

The aluminum forming category is not well suited to subcategori-
zation using any one of the factors discussed in this section.
By applying a combination of factors, such as manufacturing
processes, unit operations, raw materials, and wastewater
characteristics, the aluminum forming category can be divided
into six subcategories:

     1.  Rolling with Neat Oils
     2.  Rolling with Emulsions
     3.  Extrusion
     4.  Forging
     5.  Drawing with Neat Oils
     6.  Drawing with Emulsions or Soaps

Each manufacturing process consists of the four principle form-
ing operations plus a number o£ ancillary operations.  Each of
these unit operations must be addressed by the limitations  and
standards.  Since not all plants with a given manufacturing
process have the same number of ancillary unit operations,  some
method of equating the plants must be developed.  In addition to
the principle forming operation, there are some ancillary
operations that are unique to the principle forming operations
and others that are necessary to manufacture the final product.
For the purpose of subcategorization, the forming operation and
these closely related ancillary operations are grouped to
comprise a core operation.   Another group of operations is  not
unique to the forming operations, is not always necessary in the
manufacturing process, and does not discharge wastewater.   For
simplification, these are included with the other operations in
the core.  The core thus becomes a distinct regulatory unit that
for the purpose of establishing limits is viewed as a single
source of pollutants.

There are still a number of unit operations that do not fit into
the core.  These operations are not unique to a forming process,
discharge wastewater (usually large volumes), and are not always
necessary to the manufacturing process.   Because these operations
make significant contributions to the pollutant loadings when
they are performed, but they are not performed consistently
throughout the subcategory, they are not included in the core.
Instead, these operations are included in the subcategories as
ancillary operations that for regulatory purposes can be added to
the core when appropriate to limit the pollutant discharges from
aluminum forming plants.

Subcategorization on the basis of the core and ancillary opera-
tions as previously defined does not take into account the
different types of wastes that can be generated by rolling  and
                               133

-------
drawing.  To account for the two types of wastes generated by
rolling and drawing lubricants, four distinct operations were
formed; rolling that uses neat oils, rolling that uses emulsions,
drawing that uses neat oils, and drawing that uses emulsions or
soaps.  These four operations are still identifiable by the
industry and account for the differences in wastewater generated
by the same forming operation.  Furthermore, each can be related
to some unit of production to normalize plant practices and can
be applied to the subcategorization scheme of a core and ancil-
lary operations.  Thus, the manufacturing processes, unit opera-
tions, raw materials, and wastewater characteristics all play an
important part in subcategorizing the aluminum forming category.

Production Normalizing Parameter

In order to ensure equitable regulation of the category, effluent
limitations guidelines and standards of performance have been
established on a pollutant mass discharge basis (i.e., mass of
pollutant discharged per unit of production).  The unit of pro-
duction specified in these regulations is known as a production
normalizing parameter (PNP).  Establishing concentration limita-
tions rather than mass-based limits was considered; however, a
plant that diluted its wastewater would have an advantage in
meeting concentration-based limitations over a plant that con-
served water.  Thus, with concentration limitations a plant might
actually be penalized for having good water conservation
practices.  To avoid this possibility, the mass of pollutants in
the discharge has been related to a specific PNP to establish a
limitation that will limit the pollutant mass discharged
proportionate to an amount of production.

The approach used in selecting the appropriate PNP for a given
subcategory or ancillary operation is two-fold:  achieving a cor-
relation between production and the corresponding discharge of
pollutants and ensuring feasibility and ease of regulation.  Some
of the alternatives considered in specifying the PNP include:

     1,  Mass of aluminum processed,
     2.  Number of finished products manufactured,
     3.  Surface area of aluminum processed, and
     4.  Mass of process chemicals used.

The evaluation of these alternatives is summarized in the dis-
cussion that follows.

Mass of Aluminum Processed.  The aluminum forming industry
typically maintains production records of the pounds of aluminum
processed by an individual unit operation.  Availability of these
production data and lack of data for other production parameters,
such as area of aluminum and number of products, makes this the
most convenient parameter to use.  The aluminum forming dcp
                               134

-------
 requested  three  production  values:  the capacity production rate
 for  the  unit  operation  in question,  the maximum production rate
 achieved in  1977,  and the average production rate for 1977,  all
 in Ib/hr.  The PNP is based on  the  average  production rates
 reported in  the  dcp!s.   In  most cases, the  plants were operating
 their units  at or  near  the  capacity production rate.   The average
 production rate  will correlate  with the mass of pollutants found
 in the wastewater.

 Number of  End Products  Processed.   The number of products pro-
 cessed by  a  given  plant would not account  for the variations in
 size and shape typical  of formed products.   Extrusions,  for
 instance,  are produced  in a wide range of  sizes.  It  would be
 unreasonable  to  expect  the  quenching of a  large extrusion to use
 the  same amount  of water required for a smaller extruded product.

 Surface  Area  of  Aluminum Processed.   The area of aluminum pro-
 cessed is  not generally kept or known by industry.   In some
 cases, such  as forging  of miscellaneous shapes, surface  area data
 would be difficult  to determine.   Surface  area data would be
 difficult  to  collect.   Surface  area  is an  appropriate production
 normalizing parameter for aluminum which has been cleaned or
 etched (for  these  operations, the water use and discharge ought
 to show  a  correlation with  surface  area).

 Mass of  Process  Chemicals Used.   The mass of process  chemicals
 used(e.g., lubricants,  solvents, and cleaning or etching solu-
 tions) is  dependent on  the  processes  which  the aluminum  undergoes
 rather than the  other raw materials  used in the process.

 Selection  of  the Production Normalizing Parameter

 Two of the four  parameters  considered,  number of finished prod-
 ucts and mass of process chemicals are not  appropriate PNP s for
 the aluminum  forming category.   The  number  of finished products
 is inappropriate because of the  lack  of consistency and  uni-
 formity  in the finished  products manufactured by an aluminum
 forming  plant, particularly by  an extrusion or forging plant.
 Also the processes vary  from plant to plant even when producing
 essentially the  same product.   The mass  of  process  chemicals is
 an inappropriate PNP because the mass  of pollutants discharged is
 more directly related to the type of  operation using  the  process
 chemicals  than the amount of these compounds used,  although  the
 process  chemicals frequently enter the  wastewater.

 The surface area of product as  a PNP  would  relate  the mass of
 pollutants discharged to the surface  area of aluminum that con-
 tacts the process wastewater.   This parameter  would be appropri-
 ate for  a number of aluminum forming  operations  that,  produce
wastewater, since the mass  of pollutants entering  the wastewater
 is proportional  to the aluminum  it is  contacted  with.  The Agency
                                135

-------
is not selecting surface area as a production normalizing param-
eter because surface area is not always the most appropriate
parameter, especially in contact cooling situations where the
volume of water used is more closely related to the mass of
product.  Aluminum formed products, especially forged products or
extrusions, also come in a wide variety of shapes and the surface
area of these shapes would be difficult to determine.

The fourth parameter considered is the mass of product.  The
Agency has selected mass as the most appropriate PNP.  The mass
of pollutants can be related to the mass of aluminum processed
and most companies keep production records in terms of mass.  For
the six subcategories, the core operations are closely related to
the principle forming operation and the mass of pollutants gener-
ated from each ought to be dependent on the mass of aluminum
processed through the forming operation.  Thus, there is only one
PNP for each core based on the mass of pollutants processed
through the forming operation.  Each ancillary operation has a
separate PNP based on the mass of aluminum processed through the
ancillary operation.  An example of how the PNP's apply when
establishing mass discharge limits is shown in Section IX.

The PNP for aluminum forming is "off-kilograms" or the kilograms
of product removed from a machine at the end of a process cycle.
In the rolling process aluminum ingot enters the mill to be
processed.  Following one process cycle which may substantially
reduce the ingot's thickness, the aluminum is removed from the
rolling mill where it may be processed through another operation,
such as annealing, sizing, cleaning, or it may simply be stored
before being brought back to the rolling mill for another process
cycle, further reducing the thickness.  The mass of aluminum
removed from the rolling mill after each process cycle multiplied
by the number of process cycles is the PNP for that process.  The
core of each subcategory has one PNP which is based on the mass
of aluminum processed through the principal forming operation.
There is a different PNP for each ancillary operation which is
the mass of aluminum removed from the process following each
process cycle.  For example, the PNP for solution heat treatment
would be the mass of aluminum removed from the contact cooling
water quench that follows solution heat treatment.  In the case
of press heat treatment the PNP is still the mass of aluminum
removed from the contact cooling water quench that immediately
follows extrusion.

DESCRIPTION OF SELECTED SUBCATEGORIES

Subcategory Terminology and Usage

Each subcategory is broken into "core" and "ancillary" opera-
tions.  The core is composed of those operations that always
occur with the subcategory, are dry operations, or are an
                               136

-------
integral part of the manufacturing process. The core  limitation
is based on the mass of aluminum passed through the principle
manufacturing unit. The core limitation does not vary within a
given subcategory and applies to all the plants in that
subcategory.

Operations not included in the core are classified as ancillary
operations.  These are operations involving discharged wastewater
streams of significant pollutant concentrations and flows that
may or may not be present at any one facility.  The ancillary
operations are based on the mass of aluminum processed through
the given ancillary operations.  In other words, the mass of
aluminum cast by the direct chill method is the normalizing
parameter for casting, the mass of aluminum cleaned or etched is
the normalizing parameter for cleaning or etching.  If they are
present, the permit writer adds the appropriate pollutant
limitations to the core limitation to determine the effluent
limitation for the facility as a whole.

The ancillary operation of cleaning or etching shall include all
surface treatment operations, including chemical or electrochemi-
cal anodizing and conversion coating when performed as an inte-
gral part of the aluminum forming process.  A cleaning or etching
operation is defined by the cleaning or etching baths which are
followed by a rinse.  Multiple baths would be considered multiple
cleaning or etching operations only when each bath is followed by
a rinse and a separate limitation would apply to each bath rinse
combination.  Multiple rinses following a single bath will be
regulated by a single limitation.

In the following discussion, the aluminum forming subcategories
are presented on an individual basis.  The core and ancillary
operations included in each subcategory are briefly described,
and the appropriate production normalizing parameters are
identified.

Some plants will include more than one subcategory.   The fre-
quency of plants with more than one subcategory is tabulated
below. In these cases, the subcategories should be used as
building blocks to establish permit limitations.  It should be
noted that in most cases the ancillary operations will be
included with only one subcategory.  The ancillary operation is
associated with the core operation it is most closely associated
with.   As an example, consider a rolling plant which has both
rolling with neat oils and rolling with emulsions.  As one of the
ancillary operations, this plant has direct chill casting.   Since
the casting precedes rolling with emulsions and the rolling with
emulsions operation is. performed on the product of the casting
operation, casting will be considered an ancillary operation only
to the Rolling with Emulsions Subcategory.
                               137

-------
The lists presented in the following discussions provide informa-
tion specific to the subcategory being addressed.  The frequency
of occurrence of ancillary streams looks at each ancillary opera-
tion individually and apart from any other ancillary operations
that may be present at the same plant.  Thus, the sum of the fre-
quencies of the ancillary operations cannot be related to the
number of plants in that subcategory.  The same methods have been
applied to the frequency of subcategory overlap.  Since there are
some plants that will be in more than one subcategory, the sum of
plants in each subcategory will be larger than the number of
plants in the category.

As this table shows, 50 of the plants surveyed in this study are
included in the Rolling with Neat Oils Subcategory.  For the
majority of these plants, the core regulations can be  applied
without alteration because no ancillary streams are present.
However, continuous sheet casting is practiced at 11 plants (22
percent), and cleaning or etching of the rolled product is prac-
ticed at 9 plants (18 percent).  The presence of heat treatment
was reported at only six plants (12 percent).
                              140

-------
Over half of the plants  (33 of 50) associated with this  subcate-
gory were also associated with one or more additional subcate-
gories.  The most common case, overlap with the Rolling with
Emulsions Subcategory, was reported at 19 of the 50 plants  (38
percent).  Frequently, rolling of aluminum with emulsions is
followed by rolling to desired gauge using neat oils.  It is
important to realize that at  these plants, operations such  as
casting were considered to be associated with the emulsion  roll-
ing rather than neat oil rolling for the purpose of subcategori-
zation.  In this way, duplication of streams is avoided.  Seven
of the plants (14 percent) were included in both the Rolling with
Neat Oils and Drawing with Neat Oils subcategories.  In these
cases, the aluminum was usually first rolled and then drawn to
form the desired product.  If the drawn product was then etched
or heat treated, these operations were associated with drawing
with neat oils rather than rolling with neat oils.  In only four
cases (8 percent) was overlap with more than one other
subcategory found to exist.

As discussed in Section III (p. 100 ), the annealing operation
does not use process water.  One of the plants surveyed anneals
aluminum which is rolled with neat oils and derives the inert gas
atmosphere used in its annealing process from furnace off gases.
Because of the sulfur content of furnace fuels, the off gases
require cleaning with wet scrubbers to remove contaminants.
Other plants import cleaned gases or burn natural gas to provide
an inert atmosphere.  Since the Agency believes that this scrub-
ber is necessary to the operation of the annealing furnace,  an
allowance has been included as part of the core of the Rolling
with Neat Oils Subcategory.  For the Rolling with Neat Oils
Subcategory, two core allowances will be established, because
most plants do not have an annealing scrubber liquor flow.
Separate allowances will be established for core waste streams
without an annealing furnace scrubber and for core waste streams
with an annealing furnace scrubber.

Rolling with Emulsions Subcategory

This subcategory is applicable to all wastewater discharges
resulting from or associated with aluminum rolling operations in
which oil-in-water emulsions are used as lubricants.   The unit
operations and associated waste streams covered by this sub-
category and the appropriate production normalizing parameters
are listed below.

Of the plants surveyed in this study, 29 were classified as
belonging to the Rolling with Emulsions Subcategory.  The core
streams in this subcategory include rolling emulsions that are
expected to be present at every plant.  As shown in the preceding
list, the regulation of plants in this subcategory will usually
require consideration of waste streams associated with ancillary
operations.   Direct chill casting is associated with the rolling
operations at 20 of the plants surveyed.  Solution heat treatment
is practiced at eight plants.  Seven plants will also require
regulation of cleaning or etching baths and rinses as an ancil-
lary stream, and two plants will receive an allocation for a
cleaning or etching scrubber liquor discharge.

In all but one case (97 percent), plants in the Rolling with
Emulsions Subcategory were also included in one or more other
subcategories.   The most common case, overlap with the Rolling
with Neat Oils Subcategory, was reported at 19 of the 29 plants
(66 percent).  Frequently, rolling of aluminum with emulsions is
followed by rolling to desired gauge using neat oils.  It is
important to realize that at these plants, operations such as
direct chill casting were considered to be associated with the
emulsion rolling rather than neat oil rolling for the purpose of
subcategorization.   In this way, duplication of streams is
avoided.  Two of the plants (7 percent) were included in both the

The Extrusion Subcategory includes more plants than any other
subcategory, 163, or approximately half of the plants surveyed.
Although an accurate count was not possible from the available
data, extrusion die cleaning is expected to be present at every
extrusion plant, and this operation serves as the principal com-
ponent of the core for this subcategory.

More than half of the plants in this subcategory can be regulated
on the basis of the core allocation alone, but the other facil-
ities will require the consideration of ancillary streams.  As
shown in the preceding list, the most common ancillary operation
is heat treatment (associated with extrusion at 52 of these
plants), followed by direct chill casting  (27 percent) and
cleaning or etching (25 percent).

Although most of the plants in the Extrusion Subcategory (88
percent) are not associated with any other subcategories, some
overlap does occur.  In the most common example, nine of the
extrusion plants (6 percent) are also associated with the Drawing
with Neat Oils Subcategory.

Of the 16 plants identified with the Forging Subcategory, only 1
could be regulated by the core streams alone.  The most common
ancillary streams, cleaning or etching baths and rinses, are each
associated with 81 percent of the forging plants.  Frequently,
more than one ancillary stream was associated with a given plant.
Six of the sixteen forging plants (38 percent) involved at least
three such streams.

Most of the plants in the Forging Subcategory (81 percent) did
not have operations associated with any other subcategory.  No
overlap occurred with only one other subcategory.  Some overlap
did occur, however, with the Extrusion and Drawing subcategories.

The Drawing with Neat Oils Subcategory is the second largest
aluminum forming subcategory and contains 66 of the 277 plants
surveyed in this study.  The majority of the plants in the
Drawing with Neat Oils Subcategory can be regulated on the basis
of the core alone. Heat treatment contact cooling water and
cleaning or etching baths and rinses are the most common ancil-
lary streams in this subcategory.

Frequent overlap with other subcategories was noted.  The most
common case was with the Extrusion Subcategory; nine of the neat
oil drawing plants (14 percent) were found to have extrusion
processes as well.  In all, 36 percent of the plants in the
Drawing with Neat Oils Subcategory were also associated with one
or more other alumminum forming subcategories.

Drawing with Emulsions or Soaps Subcategory

This subcategory is applicable to all wastewater discharges
resulting from or associated with the aluminum drawing operations
which use oil-in-water emulsion or soap solution lubricants.  The

The Drawing with Emulsions or Soaps Subcategory is the smallest
of the aluminum forming subcategories, with only 13 plants.  The
principal core stream in this subcategory, spent emulsions from
drawing with emulsions or soaps, is present at all 13 plants.
For the majority of plants, the core streams accurately describe
all wastewater associated with the subcategory.  At four of the
plants (31 percent), solution heat treatment is applied to the
drawn product.  Continuous rod casting and cleaning or etching
were each reported less frequently.  Consideration of the
appropriate ancillary streams is required for these plants.

Most of the plants (69 percent) are not associated with any other
subcategories.  Overlap with other subcategories was observed at
four of the thirteen plants surveyed (31 percent).

                             SECTION V

             WATER USE AND WASTEWATER  CHARACTERISTICS
This  section presents the analytical  data  that  characterize  the
raw wastewater  and  indicate  the  effectiveness of  various waste-
water treatment processes and the  flow  data that  serve as the
basis for  developing regulatory  flows in the aluminum forming
category.  The  data were obtained  from  three sources:  long-term
or historical data, data collection portfolios  (dcp's), and  sam-
pling and  analysis programs.

DATA  SOURCES

Historical Data

A useful source of long-term or historical data available for
aluminum forming plants are  the Discharge Monitoring Reports
(DMR's) completed as a part of the National Pollutant Discharge
Elimination System  (NPDES).  All applicable DMR's were obtained
through the EPA regional offices and state regulatory agencies
for the year 1977, the last complete year  for which information
was available.  The DMR's present a summary of the analytical
results from a  series of samples taken  during a given month  for
the pollutants designated in the plant's permit.  In general,
minimum, maximum, and average values, in mg/1 or  Ibs/day, are
presented  for such pollutants as total  suspended  solids, alumi-
num,  oil and grease, pH, copper, and zinc.  The samples are
collected  from the plant outfall(s), which represents the dis-
charge(s)  from  the plant.  For facilities with wastewater treat-
ment, the  DMR's provide a measure of the performance of the
treatment  system.  In theory, these data could then serve as a
basis for  characterizing treated wastewater from aluminum forming
plants;  however, there is no influent to treatment information
and too little information on the performance of the plant at the
time  the samples were collected to use  these data in formulating
performance levels of various levels of treatment.  They do serve
as a  set of data that can be used to verify the treatability
performance levels presented in Section VII, Control and
Treatment Technology (Table VII-21, p.  743 ).

Data  Collection Portfolios

The dcp responses supplied the quantity of aluminum produced dur-
ing 1977,  as well as the average production rate  (Ib/hr),  maximum
production rate, and the rate at full capacity for each opera-
tion.   When data were supplied,  the quantity of wastewater pro-
duced by a production process and the quantity of production of
that process were added to the data base.   The average 1977 pro-
duction rate is considered most representative for relating to
                               153

-------
water use and raw waste characteristics, and has been used as the
normalizing basis for calculations.

Data supplied by dcp responses were evaluated, and two flow-to-
production ratios were calculated for each stream.  The two
ratios, water use and wastewater discharge flow, are differenti-
ated by the flow value used in calculation.  Water use is defined
as the volume of water or other fluid (e.g., emulsions, lubri-
cants) required for a given process per mass of aluminum product
and is therefore based on the sura of recycle and make-up flows to
a given process,  Wastewater flow discharged after pretreatment
or recycle (if these are present) is used in calculating the
production normalized flow--the volume of wastewater discharged
from a given process to further treatment, disposal, or discharge
per mass of aluminum produced.  Differences between the water use
and wastewater flows associated with a given stream result from
recycle, evaporation, and carryover on the product.  The produc-
tion values used in calculation correspond to the production
normalizing parameter, PNP, assigned to each stream, as outlined
in Section IV.

The production normalized flows were compiled and statistically
analyzed by stream type.  Where appropriate, an attempt was made
to identify factors that could account for variations in water
use.  This information is summarized in this section.  A similar
analysis of factors affecting the wastewater values is presented
in Sections IX, X, XI, and XII where representative BPT, BAT,
NSPS, and pretreatment discharge flows are selected for use in
calculating the effluent limitations.

The BPT discharge flows were also used to estimate flows at
aluminum forming plants that supplied EPA with only production
data.  The estimated flow was then used to determine the cost of
wastewater treatment at these facilities (see Section VIII).

The methods used in evaluation of wastewater data varied as
dictated by the intended use of the results.  For example, in
Section VI the wastewater data from effluent samples are examined
to select pollutants for consideration in regulating the
category.

Congress directed EPA to regulate pollutant discharges based on a
production normalized basis; that is, kilograms (pounds) of pol-
lutant per metric ton (ton) of production, recognizing that the
mass of pollutants discharged is proportional to the production,
as discussed in Section IV.  Thus, the mass loading data (kg of
pollutant per kkg of production) from sampled plants were
averaged to determine mass loadings typical of the different
wastewater streams.

The concentration of pollutants detected in individual samples
may not be representative of the wastewater stream due to dif-
fering degrees of dilution at each plant.

Sampling and Analysis Program

The sampling and analysis program discussed in this section was
undertaken primarily to implement the Consent Decree and to iden-
tify pollutants of concern in the industry, with emphasis on
toxic pollutants.  Samples were collected at 20 aluminum forming
facilities and subsequently analyzed.

This section summarizes the purpose of the sampling trips and
identifies the sites sampled and parameters analyzed.  It also
presents an overview of sample collection, preservation, and
transportation techniques.  Finally, it describes the pollutant
parameters quantified, the methods of analyses and laboratories
used,  the detectable concentration of each pollutant, and the
general approach used to ensure the reliability of the analytical
data produced.

Site Selection.  The plants sampled were selected to be repre-
sentative of the industry.  Considerations included the number of
operations to be represented, how well each facility represented
the subcategory as indicated by available data, potential prob-
lems in meeting technology-based standards, differences in pro-
duction processes used, and wastewater treatment in place.

Field Sampling.  After selection of the plants to be sampled,
each plant was contacted by telephone, and a letter of notifica-
tion was sent to each plant as to when a visit would be expected.
These inquiries led to acquisition of facility information neces-
sary for efficient on-site sampling.  The information resulted in
selection of the sources of wastewater to be sampled at each
plant.  The sample points included, but were not limited to,
untreated and treated discharges,  process wastewater, and par-
tially treated wastewater.

Sites visited for this sampling program are listed below by sub-
category and letter designation:

     1.  Rolling with Neat Oils -  Plants B, C, D, E, N, P,
         U, and T.

     2.  Rolling with Emulsions -  Plants B, C, D, E, H, P,
         T, and U.

     3.  Extrusion - Plants F, G,  K, L,  N,  R,  V,  and W.
                              155

-------
     4.  Forging - Plants A, J, Q, R, and W.

     5.  Drawing with Neat Oils - Plants E, H, R, and V.

     6,  Drawing with Emulsions or Soaps - Plants S and W.

Sample Collection, Preservation, and Transportation.  Collection,
preservation,and transportation of samples were accomplished in
accordance with procedures outlined in Appendix III of "Sampling
and Analysis Procedures for Screening of Industrial Effluents for
Priority Pollutants" (published by the Environmental Monitoring
and Support Laboratory, Cincinnati, Ohio, March 1977, revised,
April 1977) and in "Sampling Screening Procedure for the
Measurement of Priority Pollutants" (published by the EPA
Effluent Guidelines Division, Washington, D.C., October 1976).
The procedures are summarized in the paragraphs that follow.

Whenever practical, all samples collected at each sampling point
were taken from mid-channel at raid-depth in a turbulent, well-
mixed portion of the waste stream.  Periodically, the temperature
and pH of each waste stream sampled were measured on-site.

Each large composite (Type 1) sample was collected in a new
11.4-liter (3-gallon),  narrow-mouth glass jug that had been
washed with detergent and water, rinsed with tap water, rinsed
with distilled water, rinsed with methylene chloride, and air
dried at room temperature in a dust-free environment.

Before collection of Type 1 samples, new Tygon® tubing was cut to
minimum lengths and installed on the inlet and outlet (suction
and discharge) fittings of the automatic sampler.  Two liters
(2.1 quarts) of blank water, known to be free of organic com-
pounds and brought to the sampling site from the analytical
laboratory, were pumped through the sampler and its attached tub-
ing into the glass jug; the water was then distributed to cover
the interior of the jug and subsequently discarded.

A blank was produced by pumping an additional 3 liters (3.2
quarts) of blank water through the sampler, distributed inside
the glass jug, and poured into a 3.8-liter (1 gallon) sample
bottle that had been cleaned in the same manner as the glass jug.
The blank sample was sealed with a Teflon®-lined cap, labeled,
and packed in ice in a plastic foam-insulated chest.  This sample
subsequently was analyzed to determine any contamination con-
tributed by the automatic sampler.

During collection of each Type 1 sample, the glass jug was packed
in ice in a separate plastic foam-insulated container.  After the
complete composite sample had been collected, it was mixed to
                               156

-------
 provide  a  homogeneous  mixture,  and  two  0.95-liter  (1  quart)
 aliquots were  removed  for  metals  analysis  and  placed  in new
 labeled  plastic  0.95-liter bottles  which had been  rinsed with
 distilled  water.  One  of these  0.95-liter  aliquots  was  sealed
 with a Teflon®-lined cap;  placed  in an  iced, insulated  chest  to
 maintain it  at 4°C  (39°F),  and  shipped  by  air  for  plasma-arc
 metal analysis.   Initially,  the second  sample  was  stabilized  by
 the  addition of  5 ml (0.2  ounce)  of concentrated nitric acid,
 capped and iced  in  the same  manner  as the  first, and  shipped  by
 air  to the contractor's facility  for atomic-absorption  metal
 analysis.

 Because  of subsequent  EPA  notification  that the acid  pH of the
 stabilized sample fell outside  the  limits  permissible under
 Department of  Transportation regulations for air shipment,
 stabilization  of  the second  sample  in the  field was discontinued.
 Instead, this  sample was acid-stabilized at the analytical
 laboratory.

 After removal  of  the two 0.95-liter (1  quart)  metals  aliquots
 from the composite  sample,  the  balance  of  the  sample  in the
 11.4-liter (3  gallon)  glass  jug was  subdivided for  analysis of
 nonvolatile  organics,  asbestos, conventional,  and  nonconventional
 parameters.  If a portion  of this 7.7-liter (2 gallon)  sample was
 requested  by an industry representative for independent analysis,
 a 0.95-liter (1 quart) aliquot  was  placed  in a sample container
 supplied by  the representative.

 Sample Types 2 (cyanide) and 3  (total phenol) were  stored in  new
 bottles  which had been iced  and labeled, 1-liter (33.8  ounce)
 clear plastic  bottles  for Type  2, and 0.47-liter (16  ounce) amber
 glass for  Type 3.  The bottles had  been cleaned by  rinsing with
 distilled  water,  and the samples were preserved as  described
 below.

 To each Type 2 (cyanide) sample, sodium hydroxide was added as
 necessary  to elevate the pH  to  12 or more  (as measured  using pH
 paper).   Where the presence  of  chlorine was suspected,  the sample
 was  tested for chlorine (which would decompose most of  the
 cyanide) by using potassium  iodide/starch  paper.  If  the paper
 turned blue, ascorbic  acid crystals  were slowly added and dis-
 solved until a drop of the sample produced no change  in the color
 of the test  paper.  An additional 0.6 gram (0.021 ounce) of
 ascorbic acid was added, and  the sample bottle was sealed (by a
 Teflon®-lined  cap), labeled,  iced,  and  shipped for analysis.

To each Type 3 (total  phenol) sample, phosphoric acid was added
 as necessary to reduce the pH to 4 or less (as measured using pH
 paper).   Then,  0.5 gram (0.018 ounce) of copper sulfate was added
 to kill  bacteria, and  the sample bottle was sealed  (by  a
 Teflon®-lined cap), labeled,  iced,  and  shipped for analysis.
                               157

-------
Each Type 4 (volatile organics) sample was stored in a new 125-ml
(4.2 ounce) glass bottle that had been rinsed with tap water and
distilled water, heated to 105°C (221°F) for one hour, and
cooled.  This method was also used to prepare the septum and lid
for each bottle.  Each bottle, when used, was filled to overflow-
ing, sealed with a Teflon®-faced silicone septum (Teflon® side
down) and a crimped aluminum cap, labeled, and iced.  Hermetic
sealing was verified by inverting and tapping the sealed con-
tainer to confirm the absence of air bubbles.  (If bubbles were
found, the bottle was opened, a few additional drops of sample
were added, and a new seal was installed.)  Samples were main-
tained hermetically sealed and iced until analyzed.

Wastewater samples were collected in two stages:   screening and
verification.  Ideally, the screening phase involves collection
of samples from every waste stream in the category.  Pollutants
that were not detected during screening were not considered
further in the study.  Because of the tight schedule of this
study, there was not time to analyze all of the samples obtained
during screening before verification sampling began.  Therefore,
verification samples were analyzed for almost all of the toxic
pollutants, as well as selected conventional and nonconventional
pollutants.

Sample Analysis.  Samples were sent by air to one of five labora-
tories:  Cyrus Wm. Rice Division of NUS Corporation of
Pittsburgh, Pennsylvania; ARO, Inc. of Tullahoma, Tennessee;
Systems Science and Software  (SSS) of San Diego,  California:
Spectrix of Houston, Texas; and Radian Corporation of Austin,
Texas.  Screening samples went to Rice; there the samples were
split for metals analysis.  An aliquot of each metal sample
received by Rice was sent to EPA's Chicago laboratory for
inductively coupled argon plasma emission spectrophotometry
(ICAP) analysis; Rice retained an aliquot for atomic absorption
spectrophotometry (AA).  Twenty-two metals were analyzed by ICAP,
and five metals were analyzed by AA, as follows:

                           Thallium
                           Mercury

Many o£ the metals analyzed by ICAP are not  classified as pollu-
tants and are not reported in this document  as pollutants.  They
are considered only because they consume lime and increase  sludge
production in wastewater treatment facilities.

Verification samples went to Radian or ARO when metal analysis
was performed by AA.  Since metals analysis  of screening samples
was complete before verification metals analysis began, Radian
analyzed the samples only for metals shown to be significant  in
the aluminum forming category or those expected to consume  large
amounts of lime.

Some verification samples were sent to System, Science and
Software (SSS), Spectrix, Radian, or Rice, where analysis for the
organic toxic pollutants was done.

Due to their very similar physical and chemical properties, it is
extremely difficult to separate the seven polychlorinated
biphenyls (pollutants 106 to 112) for analytical identification
and quantification.  For that reason, the concentrations of the
polychlorinated biphenyls are reported by the analytical
laboratory in two groups:  one group consists of PCB-1242,
PCB-1254, and PCB-1221; the other group consists of PCB-1232,
PCB-1248, PCB-1260, and PCB-1016.  For convenience,  the first
group will be referred to as PCB-1254 and the second as PCB-1248.

The samples were not analyzed for Pollutant 129, 2,3,7,8-tetra-
chlorodibenzo-p-dioxin (TCDD) because no authentic reference sam-
ple was available to the analytical laboratory.

Past studies by EPA and others have identified many nontoxic
pollutant parameters useful in characterizing industrial waste-
waters and in evaluating treatment process removal efficiencies.
Some of these pollutants may also be selected as reliable indi-
cators of the presence of specific toxic pollutants.  For these
reasons,  a number of nontoxic pollutants were also studied for
the aluminum forming category.   These additional pollutants may
be divided into two general groups:
                               159

-------
     Conventional
Nonconventional
     total suspended solids  (TSS)  chemical oxygen demand  (COD)
     oil and grease                phenols  (total)
     pH                            total organic  carbon  (TOG)
                                   total dissolved solids  (IDS)

Congress has defined the following criteria for the selection of
conventional pollutants:

     (1)  Generally those pollutants which  are naturally
          occurring, biodegradable, oxygen  demanding materials,
          and solids which have characteristics similar  to
          naturally occurring biodegradable substances; or,

     (2)  Include those classes of pollutants which tradi-
          tionally have been the primary focus of wastewater
          control.

In addition, aluminum, calcium, magnesium,  alkalinity, total dis-
solved solids, and sulfate were measured to provide data to
evaluate the cost of lime and settle treatment of certain
wastewater streams.

The analytical quantification levels used in evaluation  of the
sampling data reflect the accuracy of the analytical methods
employed.  Below these concentrations, the  identification  of the
individual compounds is possible, but quantification is diffi-
cult.  Pesticides and PCB's can be analytically quantified at
concentrations above 0.005 mg/1, and other  organic toxic levels
above 0.010 mg/1 levels associated with toxic metals are as
follows:  0.100 mg/1 for antimony; 0.10 mg/1 for arsenic;  1 x
107 fibers/1 for asbestos; 0.010 mg/1 for beryllium; 0.002 mg/1
for cadmium; 0.005 mg/1 for chromium; 0.009 mg/1  for copper;
0.100 mg/1 for cyanide; 0.02 mg/1 for lead; 0.0001 mg/1  for
mercury; 0.005 mg/1 for nickel; 0,010 mg/1  for selenium; 0.020
mg/1 for silver; 0.100 mg/1 for thallium; and 0.050 mg/1 for
zinc.

These detection limits are not the same as published detection
limits for these pollutants by the same analytical methods.  The
detection limits used were reported with the analytical data and
hence are the appropriate limits to apply to the  data.  Detection
limit variation can occur as a result of a  number of laboratory-
specific, equipment-specific, and daily operator-specific
factors.  These factors can include day-to-day differences in
machine calibration, variation in stock solutions, and variation
in operators.

-------
Quality  Control.   Quality  control  measures  used in performing all
analyses  conducted for  this program complied with the  guidelines
given  in  "Handbook for  Analytical  Quality Control in Water  and
Wastewater Laboratories"  (published by EPA  Environmental
Monitoring and Support  Laboratory,  Cincinnati,  Ohio, 1976).   As
part of the  daily  quality  control  program,  blanks (including
sealed samples of  blank water  carried to each sampling site and
returned  unopened,  as well as  samples of blank  water used in  the
field),  standards,  and  spiked  samples were  routinely analyzed
with actual  samples.  As part  of the overall  program,  all
analytical instruments  (such as balances, spectrophotometers,  and
recorders) were routinely  maintained and calibrated.

The atomic-absorption spectrometer  used for metal analysis was
checked to see that it  was operating correctly  and performing
within expected limits.  Appropriate standards  were included
after at  least every 10 samples.  Also, approximately  15 percent
of the analyses were spiked with distilled  water  to assure
recovery  of  the metal of interest.  Reagent blanks were analyzed
for each  metal, and sample values were corrected  if necessary.

WATER USE AND WASTEWATER CHARACTERISTICS

To simplify  the presentation of the sampling  data,  tables were
developed that present  ranges  of concentrations with the number
of samples in which each pollutant  was found  within these ranges.
For each waste stream a frequency  of occurrance table  is pre-
sented for all 129  toxic pollutants.  For those pollutants
detected  above analytically quantifiable concentrations in any
sample of that wastewater stream,  the actual  analytical data  is
presented in a second table.  Where no data is  listed  for a
specific day of sampling, it indicates that the wastewater
samples for  the stream were not collected.

The statistical analysis of data includes some  samples measured
at levels considered not quantifiable.   The base  neutrals, acid
fraction, and volatile  organics are considered  not quantifiable
at concentrations  equal to or less  than 0.010 mg/1.  Below this
level,  organic analytical results are not quantitatively accu-
rate; however, the analyses are useful to indicate the presence
of a particular pollutant.  Nonquantifiable results are desig-
nated in the tables with an asterisk (double  asterisk  for
pesticides).

When calculating averages from the  organic  sample  data, non-
quantifiable results were assumed to be zero.  Organics data
reported as  not detected (ND)  are not averaged.   For example,
three samples reported as ND,  *, 0.021  mg/1 would  average as
0.010 mg/1.

In the following discussion, water use and field sampling data
are presented for each core operation by subcategory.  Discus-
sions of the water use and discharge rates and  field sampling
data for the ancillary operations follows thereafter.  Appro-
priate tubing or background blank and source water concentrations
are presented with the summaries of the sampling data.  Figures

CORE OPERATIONS ASSOCIATED WITH MAJOR FORMING PROCESSES

Rolling

Rolling with Neat Oils Spent Lubricant.  As described in Section
III, the cold rolling of aluminum products typically requires the
use of mineral oil or kerosene-based lubricants.  The oils are
usually recycled with in-line filtration and periodically dis-
posed of by sale to an oil reclaimer or by incineration.  Because
discharge of this stream is not practiced, limited flow data were
available for analysis.  Of the 50 plants surveyed that use neat
oil rolling lubricants, water (oil) use could be calculated for
only four.  These data are presented and summarized in Table V-l.
None of the plants provided sufficient flow data to calculate the
degree of recycle practiced or the discharge flow of this stream.

Toxic pollutant frequency occurence data are presented in Table
V-2.  Wastewater sampling data for neat oil lubricants are
presented in Table V-3.

Rolling with Emulsions Spent Emulsion.  Of the  plants surveyed,
29 rolling operations were identified that use oil-in-water emul-
sions as coolants and lubricants.  Rolling emulsions are typi-
cally recycled using in-line filtration treatment.  Several
plants discharge a bleed stream, but periodic discharge of the
recycled emulsion is more commonly practiced.

Water use, wastewater factors, and percent recyle corresponding
to this stream are summarized In Table V-4.

Toxic pollutant frequency occurrence data are presented in Table
V-5.  Table V-6 summarizes the field sampling data for toxic and
                               162

-------
 selected  conventional  and  nonconventional  pollutants.   This
 stream  is  characterized by high  levels  of  COD  (79.8  to  1,520,000
 mg/1),  TOC (38.0  to  560,000 mg/1),  and  phenolic  compounds  as
 measured  by total phenolics-4AAP (0.210  to 49.0  mg/1).   Several
 toxic organic pollutants were  detected  in  the  spent  emulsions  at
 significant concentrations.  These  included  several  of  the
 polynuclear aromatic hydrocarbons  (PAH)  and  polychlorinated
 biphenyls  (PCBs).

 Roll Grinding Spent  Emulsion.  The  steel rolls used  in  rolling
 operations require periodic machining to remove  aluminum buildup
 and surface imperfections.  In responding  to the dcpfs,  most
 plants  did not  interpret the scope  of aluminum forming  processes
 to include roll grinding.  For this reason,  a  number of plants
 were contacted by telephone to supplement  the  dcp responses.
 Although  the survey  for this stream is not as  complete  as  for  the
 other aluminum forming processes,  it provided  a  basis for  the
 analysis  of water use and  wastewater rates typically associated
 with roll  grinding.  This  information is summarized  in  Table V-7,
 along with the degree of recycle or disposal mode practiced at
 those plants.

 A roll  grinding operation  was  sampled at one facility.   This sam-
 ple was not from an  emulsified stream.  Due  to the nature  of the
 roll grinding operation, it is assumed that  the wastewater char-
 acteristics of the resultant spent emulsions are similar to those
 of the  rolling with  emulsions  spent emulsion waste stream.  Toxic
 pollutant  frequency  occurrence data for the nonemulsified  stream
 are presented in Table V-S.  The field sampling  data are summa-
 rized in Table V-9.  This  waste stream is  characterized  by high
 levels  of  oil and grease (107 mg/1), suspended solids (118 mg/1),
 and COD (230 mg/1).  Only  one of the toxic organic pollutants,
 acrolein, was detected (0.05 »g/l).

 Extrusion

 Extrusion Pie Cleaning Bath*  As discussed in Section III
 (p.91  ),the steel  dies used in extrusion require frequent dres-
 sing to ensure the necessary dimensional precision and  surface
 quality of the product.  The aluminum that has adhered  to  the  die
 orifice is typically removed by soaking the die  in a caustic
 solution.  A few plants indicated that mechanical brushing could
be used to clean very simple dies, but caustic cleaning  is a much
more common practice.  As with roll grinding, it was necessary to
 supplement the survey of die cleaning operations with telephone
 calls to several plants.   Of the 163 extrusion plants, 37  are
known to have die cleaning facilities.  Water use and wastewater
values corresponding to the die cleaning caustic bath were
                               163

-------
calculated for plants for which Information was available.  This
information is presented and statistically summarized in Table
V-10.

Although recycle of the caustic solution, as such, is never
practiced, periodic discharge of these stagnant baths is common.
For this reason, water use  (make-up rate) and wastewater  (dis-
charge rates) are normally  identical.  Variations in the water
use in caustic die cleaning baths may result from the following:

        Intricacy and size  of the die orifice.
        Aluminum alloy being extruded.
        Concentration of caustic used.
        Individual plant practices.

Sufficient information is not available, however, to analyze the
effect of these factors.

Wastewater samples were not collected from extrusion die cleaning
baths during the sampling program.  Due to the nature of the
extrusion die cleaning operation, it is assumed that the waste-
water characteristics of this stream are similar to discharges
from cleaning or etching baths.  Untreated wastewater data for
cleaning and etching baths  are summarized in Tables V-50 and
V-51.

Extrusion Die Cleaning Rinse.  After caustic treatment, the
extrusion dies are rinsed with water.  At some plants, the dies
are simply hosed off; at others, a rinse tank is used for this
purpose.  Most of the plants contacted indicated that rinsing was
required to avoid damage to the die and the material being
extruded.  Water use and wastewater factors could be calculated
for only nine of the thirty plants.  This information is pre-
sented and summarized in Table V-ll.  As can be seen, water use
is small and recycle, as such, is not practiced.  Water use does
not appear to be affected by differences in rinsing method (i.e.,
hose or rinse tank).  Other factors, such as the intricacy of the
dies, concentration of caustic used, aluminum alloy being
extruded, and individual plant practices, could account for
variations in water use.  Sufficient data were not available to
determine the degree of influence of these factors.

Toxic pollutant frequency occurrence data are presented in Table
V-12.  Table V-13 summarizes the field sampling data for toxic
and selected conventional and nonconventional pollutants detected
above the analytically quantifiable levels.  This waste stream is
characterized by high concentrations of aluminum (9.41 to 400
mg/1), dissolved solids (3,230 to 7,200 mg/1), and low concentra-
tions of suspended solids (28 to 120 mg/1) and oil and grease
(<2.9 to 8 mg/1).  Only five of the toxic organic pollutants were
detected during sampling.
                                164

-------
Extrusion Die Cleaning Scrubber Liquor.  Of  the plants  surveyed,
two Indicated the use of wet scrubbers associated with  their die
cleaning operations.  As with the other die  cleaning  streams,
however, this survey may not accurately represent the total
number of plants with this waste stream.  Wet scrubbers may be
required to treat fumes from the caustic die cleaning operation
in order to control air pollution emissions  and ensure  a  safe
working environment.  Water use and wastewater factors  are
calculated in Table V-14.  Toxic pollutant frequency  occurrence
data are presented in Table V-15.  Table V-16 summarizes  the
field sampling data for toxic and selected conventional and
nonconventional pollutants detected above the analytically
quantifiable levels.  This waste stream is characterized  by
relatively high levels of oil and grease (57.6 mg/1) and  dis-
solved solids (330 mg/1).  The toxic metals, when detected, were
present at levels well below their treatability levels.

Extrusion Press Scrubber Liquor.  Of the 163 extrusion  plants
surveyed, two plants reported the use of wet scrubbers  at the
extrusion presses to remove caustic fumes.  These fumes occur as
a result of cleaning aluminum from extrusion presses between
operations.

One of these plants reported sufficient data for the calculation
of wastewater values.  The scrubber at this plant runs  continu-
ously without recycle and has water use and wastewater values of
2,071 1/kkg.   The other plant, while not supplying enough
information to allow calculation of these values, reported that
their scrubber is only run intermittently.  These data appear in
Table V-17.  This waste stream was sampled at only one plant.
Toxic pollutant frequency occurrence data are presented in Table
V-18.  The field sampling data are summarized in Table V-19.  As
can be seen in the table, this stream is characterized by low
levels of suspended solids (5 mg/1) and elevated levels of dis-
solved solids (357 mg/1).  All of the toxic metals were detected
well below their treatability levels.

Extrusion Dummy Block Contact Cooling Water.  As described in
Section III (p.90 ), a dummy block is placed between the ram and
ingot during the direct extrusion process.  After the extrusion
is complete,  the ingot butt and dummy block are released  from the
press.  Typically, the dummy blocks are allowed to air cool; how-
ever, of the 163 extrusion plants, three indicated that water was
used for this purpose.  As can be seen in Table V-20, none of
these plants recycle the cooling water.  Data were available to
calculate water use and wastewater discharge rates for two of the
three plants.
                                165

-------
Toxic pollutant frequency occurrence data are presented in Table
V-21.  Data from wastewater sampling of dummy block cooling water
are presented in Table V-22.  This waste stream is characterized
by elevated concentrations of oil and grease (74 mg/1) and dis-
solved solids (50 mg/1).  Only one toxic organic pollutant
(chloroform) was detected (0.08 mg/1).  None of the toxic metals
were detected.

Forging

There are no core waste streams that are unique to the forging
operation.

Drawing

Drawing with Neat Oils Spent Lubricant.  Of the 277 plants sur-
veyed"]66 draw aluminum products using neat oil lubricants.  Two
plants avoid discharge of this stream by 100 percent recycle of
the drawing oil.  Most of the plants dispose of the spent oil by
incineration or contractor hauling and did not provide the flow
data required to calculate water (oil) use and wastewater dis-
charge (oil) values.  Table V-23 shows the water use and waste-
water values for the plants that supplied sufficient information
for the calculation of these values.

No wastewater samples were collected from neat oils for drawing.

Drawing with Emulsions or Soaps Spent Emulsion.  Of the plants
surveyed, nine draw aluminum products using oil-in-water emul-
sions, and four indicated that soap solutions were used as draw-
ing lubricants.  Water use and wastewater factors calculated for
this stream are presented and summarized in Table V-24.  As can
be seen, the solutions are frequently recycled and discharged
periodically after their lubricating properties are exhausted.
Wastewater discharge factors were calculated for seven of the 13
plants.  As shown in Table V-24, the wastewater discharge rates
associated with these plants vary considerably.  Analysis of the
data has shown that this variation is related to differences in
the dimension of wire being drawn.   The amount of lubricant
required for drawing a given length of wire is roughly the same
for fine and coarse wire.  Since the weight of finer wire is
less, the corresponding production figures will be lower.  As a
result, the wastewater factors calculated as flow per unit
production will be higher for lubricants used in fine wire
drawing than in drawing of coarse wire.

Toxic pollutant frequency occurrence data are presented in Table
V-25.  Table V-26 summarizes the field sampling data for the
toxic and selected conventional and nonconventional pollutants
detected above analytically quantifiable levels.  This waste
                                166

-------
 stream  is  characterized by  extremely high  levels  of  oil  and
 grease  (51,500 mg/1) and the presence  of certain  toxic organic
 pollutants.

 Swaging.   Swaging  is frequently associated with drawing  opera-
 tions and  has been included in the Drawing with Neat Oils
 Subcategory.  Swaging  is used as an initial  step  in  drawing with
 tube or wire.  By repeated blows of one or more pairs of opposing
 dies, a solid point is formed.  This can then be  inserted  through
 the die and gripped for drawing.  In a few cases, swaging  is used
 in tube forming without a subsequent drawing operation.  Some
 lubricants, such as waxes and kerosene, may  be used  to prevent
 adhesion of metal or oxide on the dies.  Discharge of swaging
 lubricants was not reported by any of the  plants  surveyed  in this
 study.

 CORE OPERATIONS NOT ASSOCIATED WITH SPECIFIC MAJOR FORMING
 PROCESSES

 Sawing Spent Lubricant.  Although sawing is  associated with
 nearly all aluminum forming operations, only 12 of the plants
 surveyed reported the use of saw oil emulsions.   Because plants
 frequently failed to mention minor streams that are  not  dis-
 charged, the actual number of plants using saw lubricants  is
 probably much higher.  The lubricants are  frequently recycled
 and,  in most instances, discharge from the system is limited to
 carryover  and disposal by contractor hauling.  Only  three  plants
 reported direct or indirect discharge of saw oils.

Water use  and wastewater factors were calculated  for plants pro-
 viding flow and production data corresponding to  the stream.
These factors are shown and summarized in Table V-27.

Field samples of sawing spent lubricant were not  collected.  Due
 to the nature of the lubricants used in the  sawing operation, it
 is assumed that the wastewater characteristics of this waste
 stream are similar to those of the rolling with emulsions  spent
emulsion waste stream.   These data are presented  in Tables V-5
and V-6.

Decreasing Spent Solvents.   Although 34 solvent degreasing
operations have been identified from dcp responses, no discharge
 is typically associated with this process, and little flow data
were provided.  Vapor degreasing,  the predominant method of sol-
vent cleaning in the aluminum forming industry, is described in
Section III (p. 103 ).   A number of toxic organic pollutants,
 including trichloroethylene, 1,1,1-trichloroethane, and perchlo-
roethylene, are commonly used solvents for vapor  degreasing.  The
solvents are frequently reclaimed by distillation, either  on-site
or by an outside recovery service.
                               167

-------
Toxic pollutant frequency occurrence data are presented in Table
V-28.  Field sampling data for cleaning solvent streams are
summarized in Table V-29.  Besides the presence of volatile
organic pollutants mentioned above, this waste stream is charac-
terized by high levels of oil and grease (2,180 mg/1), COD (330
mg/1), and TOG (143 mg/1).

Annealing Atmosphere Scrubber Liquor.  As described in Section
III  (p. 100 )., annealing is used to soften work-hardened and
solution-heat-treated alloys, to relieve stress, and to stabilize
the  properties and dimensions of the aluminum product.  In some
cases, it is necessary to control the atmosphere within the
annealing furnace.  At elevated temperatures, the presence of
water vapors  can disrupt the oxide film on the surface of the
product,  especially if the atmosphere is also contaminated with
ammonia or sulfur compounds.  Inert gas atmospheres can be used
within the furnace to avoid possible detrimental effects, such as
blistering, discoloration, and a decrease in tensile properties.
At some plants, natural gas is burned to generate an inert atmos-
phere.  At one of the aluminum forming plants surveyed, flue
gases from the burning of fuel to heat the annealing furnace are
used as the furnace atmosphere.  Due to the sulfur content of
furnace fuels; however, the off gases require treatment by wet
scrubbers before they can be used as an inert atmosphere for heat
treatment.  The scrubber in use at this plant was reported to
require a relatively large flow of water which is extensively
recycled (more than 99 percent).  The water use and wastewater
values calculated for this stream are shown in Table V-30.

Toxic pollutant frequency occurrence data are presented in Table
V-31.  Table V-32 summarizes the field sampling data for those
pollutants detected above analytically quantifiable levels.  This
waste stream is characterized by high levels of sulfates if the
furnace fuel has a high sulfur content.

ANCILLARY OPERATIONS

Heat Treatment

Solution and Press Heat Treatment Contact Cooling Water.  Heat
treatment of aluminum products frequently involves the use of a
water quench in order to achieve desired metallic properties.  At
the  277 aluminum forming plants surveyed, 88 solution heat
treatment processes were identified that involve water quenching.

The  field samples from heat treatment quenching processes have
been identified and compiled according to the aluminum forming
operation that it follows (i.e., rolling, forging, drawing, and
extrusion).  Additional differentiation was made between press
and  solution heat treatment of extrusions.   The wastewater
streams and the tables which list the water use, percent recycle,

The water use factors calculated for this stream were analyzed to
determine if a relationship exists between water use requirements
and the type of products being quenched (extrusions, forgings,
etc.) or the method of heat treatment used (e.g., press versus
solution heat treatment of extrusions).  It was determined that
neither of these factors account for the variations in water use.
Heat treatment water requirements are independent of the major
forming process which precedes the heat treatment operation.  The
water requirements are a function of several variables, including
the mass and surface area of the aluminum, the time allowed for
cooling, and the temperature gradient.

Since the water use requirements are independent of the major
forming process which precedes the operation, it is assumed that
the pollutant loadings in the discharged wastewater are also
independent and will be similar for the various heat treatment
operations.  For regulatory purposes the wastewater discharge
values for all the heat treatment operations will be combined
into a single value for all solution and press heat treatment
operations.

Cleaning or Etching Bath.   As described in Section III (p.102 ),
a variety of chemical solutions are used for cleaning purposes or
to provide the desired finish for formed aluminum products.
                               169

-------
These treatments and their associated rinses are usually combined
in a single line of successive tanks. Wastewater discharged from
these lines is typically commingled prior to treatment or
discharge.

The acid, alkaline, and detergent solutions used in cleaning or
etching lines are usually maintained as stagnant baths into which
the products are immersed.  Chemicals are added as required to
make up for losses due to evaporation, carryover, and splash-out.
In this survey, most of the plants with cleaning or etching lines
did not indicate discharge of these chemical dips.  A few plants
reported periodic discharge of cleaning or etching compounds,
usually following treatment.  Other plants indicated that the
chemical dip is hauled periodically by an outside contractor or
disposed of on-site.  Water use and wastewater discharge rates
for this stream are presented in Table V-48.

Table V-49 presents the frequency of occurrence of toxic pol-
lutants for this wastewater stream type.  Table V-50 summarizes
the field sampling data for those pollutants detected above
analytically quantifiable levels.  This waste stream is charac-
terized by high levels of several of the toxic metals, copper,
chromium and lead, oil and grease (7 to 100 mg/1), suspended
solids (1 to 348 mg/1), aluminum (30 to 70,000 mg/1), dissolved
solids (27,600 to 284,000 mg/1), and TOG (1 to 3,550 mg/1).

Cleaning or Etching Rinse.  Rinsing is usually required following
if
successive chemical treatments within cleaning or etching lines.
The most common methods are spray rinsing or immersion in a con-
tinuous-flow rinse tank.  The number of rinses within a given
line varied from plant to plant, depending on the kind of surface
treatment applied,

Water use and wastewater values calculated for the cleaning or
etch lines at aluminum forming plants are shown in Table V-51.
As can be seen, cleaning or etching lines with multiple rinses
tend to have higher water use and wastewater discharge values.
Direct correlations between these factors cannot be established
on the basis of these data.  A more detailed discussion of fac-
tors which could account for variations in wastewater discharge
of this stream is presented in Section IX.  The percent of
recycled rinse water could not be calculated because of the
difficulty in defining the amount of water used.  This was caused
by countercurrent and stagnant rinses, carryover, and other
practices peculiar to the cleaning or etching lines in the
aluminum forming category.

Toxic pollutant frequency occurrence data are presented in Table
V-52.  Table V-53 summarizes the field sampling data for those
pollutants detected above analytically quantifiable levels. This
waste stream, like cleaning or etching baths, is characterized by
                               170

-------
elevated concentrations of the toxic metals, copper,  chromium,
and lead.  In addition, nickel and zinc were present  at high
levels  in many samples.  Oil and grease and suspended solids were
also present at high levels, but lower relative to the baths, as
would be expected.

Cleaning or Etching Scrubber Liquor.  Of the 40 plants with
cleaning and etching lines,six indicated that wet scrubbers are
associated with these operations.  Fumes from caustic or acid
baths may require treatment to control air pollution  emissions
and ensure a safe working environment.  Sufficient flow data were
available to calculate water use from two of the six  plants, and
wastewater values were available from three of the six plants.
This information is summarized and presented in Table V-54.

Toxic pollutant frequency occurrence data are presented in Table
V-55.  Table V-56 summarizes the field sampling data  for those
pollutants detected above the analytically quantifiable levels.
This waste stream is characterized by low levels of contamina-
tion, as exhibited by suspended solids at 12 mg/1.

Forging Scrubber Liquor.  Of the 16 forging plants surveyed,
three indicated that wet scrubbers were used to control
particulates and smoke generated from the partial combustion of
oil-based lubricants in the forging process.  Water use and
wastewater discharge rates are summarized in Table V-57.

Toxic pollutant frequency occurrence data are presented in Table
V-58.  Table V-59 summarizes the field sampling data  for the
toxic and selected conventional and nonconventional pollutants
detected above the analytically quantifiable levels.  This waste
stream is characterized by the presence of eight toxic organic
pollutants, five of which were polynuclear aromatics.  The five
were present at concentrations ranging from 0.018 to  0.075 mg/1.
High levels of oil and grease (162 mg/1), COD (349 mg/1), and
dissolved solids (388 mg/1) are also characteristic of this waste
stream.
Casting

Direct Chill Casting Contact Cooling Water.
surveyed, 61 aluminum forming and
ng water.  Of the plants
27 primary aluminum plants
indicated that they cast aluminum or aluminum alloys using the
direct chill method.  Because the ingot or billet produced by
direct chill casting is used as stock for subsequent rolling or
extrusion, this wastewater stream is considered to be an ancil-
lary stream for the Rolling with Emulsions and Extrusion
Subcategories.

Contact cooling water is used in the direct chill casting method
to spray the ingot or billet as it drops from the m<5ld and then
                               171

-------
to quench it as  it is  immersed  in a cooling tank at the bottom of
the casting pit.  As described  in Section III  (p. 96 ), the cool-
ing water may be contaminated by lubricants applied to the mold
before and during the  casting process.  Some plants discharge
this cooling water stream without recycle, but it is commonly
recirculated through a cooling  tower.  Even with recycle, peri-
odic discharge or the  discharge of a continuous bleed stream is
required to prevent the accumulation of dissolved solids.  Of the
48 aluminum forming plants for which information was available,
30 recycle the contact cooling water stream used in direct chill
casting.  The average  recycle rate at these plants was 96
percent, but the reported values ranged between 50 and 100
percent.

The calculated water use, percent recycle and wastewater values
corresponding to direct chill casting cooling water streams at
aluminum forming plants are presented in Table V-60, along with a
statistical summary of this data.  For comparative purposes, the
calculated water use,  percent recycle, and wastewater values for
primary aluminum plants with direct chill casting operations are
presented in Table V-61.

Toxic pollutant  frequency occurrence data are presented in Table
V-62.  The field sampling data  for those pollutants detected
above analytically quantifiable levels are summarized in Table
V-63.  This waste stream is characterized by the presence of
certain toxic organic  pollutants at levels ranging from 0.500
mg/1 to below the level of detection.  It is also characterized
by elevated levels of  oil and grease (5 to 214 mg/1) and
suspended solids (1 to 220 mg/1).

Continuous Rod Casting Contact Cooling Water.   Three of the
aluminum forming plants surveyed in this study use continuous
casting methods to manufacture aluminum rod for subsequent draw-
ing.  Four primary aluminum plants also have continuous rod
casting operations.  This process, also referred to as Properzi
or wheel casting, is described  in Section III  (p. 98 ).  Although
the cooling water associated with continuous rod casting is, for
the most part, noncontact, some contact with the freshly cast
aluminum bar as it leaves the ring mold is difficult to avoid.
For this reason, the cooling water used in continuous rod casting
operations is classified as an ancillary stream associated with
the Drawing with Neat Oils and Drawing with Emulsions or Soaps
Subcategories.

Water use and wastewater factors corresponding to this stream
could be calculated for only one of the aluminum forming con-
tinuous rod casting plants.  At this facility no recycle of the
cooling water was practiced.  Water use and wastewater rates
could not be calculated for the other aluminum forming plant
                                172

-------
known to recycle and periodically discharge  this  stream.  The
other plant indicated that contact cooling water  was not used.
This information is presented in Table V-64.

No field samples were collected of this  cooling water  stream.
Due to the nature of the continuous rod  casting operation, it is
assumed that the wastewater characteristics  of this stream are
similar to those of the direct chill casting contact cooling
water waste stream.  These data are presented in  Tables V-62 and
V-63.

Continuous Rod Casting Spent Lubricant.  As  discussed  in Section
III (p. 98 ), in continuous casting operations, oil-in-water
emulsions are used as lubricants.  Both  of the rod casting plants
providing information practiced total recycle of  this  stream,
although one aluminum forming plant indicated that periodic dis-
posal was required.  Sufficient flow and production data were not
available to calculate water use or wastewater flows for this
stream.  Some recycle information is presented in Table V-65.

No continuous rod casting lubricant field samples were col-
lected.  Due to the nature of the lubricant used  in the continu-
ous rod casting operation, it is assumed that the wastewater
characteristics of this waste stream are similar  to those of the
rolling with emulsions spent emulsion waste  stream.  These data
are presented in Tables V-5 and V-6.

Continuous Sheet Casting Spent Lubricant.  Of the 277  plants sur-
veyed in the aluminum forming study,11  cast aluminum  sheet pro-
ducts using continuous techniques such as the Hunter or Hazelett
methods.  No plants in the primary aluminum  industry reported
casting aluminum sheet products using continuous  methods.  While
continuous sheet or strip casting uses only noncontact cooling
water,  a few plants indicated that lubricants were required for
the associated rolling line.  Oil-in-water emulsions,  graphite
solutions, and aqueous solutions of magnesia can  be used for this
purpose.  Of the plants surveyed, five reported the use of lubri-
cants in their continuous sheet casting  operations.  The lubri-
cants were always recycled and two of the plants  indicated that
periodic disposal of this stream was required.  Water  use and
wastewater rates of this stream are shown for the plants in Table
V-66.   Other plants reported periodic disposal of the  lubricant,
but provided no flow data.  Six additional facilities  with con-
tinuous sheet casting did not indicate the use of a rolling
lubricant.

No wastewater samples were collected from continuous sheet cast-
ing operations.   Due to the nature of the type of lubricant used
in this operation,  it is assumed that the wastewater character-
istics of this waste stream are similar  to those  of the rolling
                               173

presented  in Tables V-5 and V-6.
These data are
Stationary Casting.  All of the 16 stationary casting  facilities
surveyed  in  the  aluminum forming  study  indicated  that  contact
cooling water is not associated with stationary casting.  Any
water used to cool  the molds  is strictly noncontact.   Small quan-
tities of water  are sometimes sprayed onto the surface of the
molten metal in  stationary casting operations.  Although not
reported to occur in aluminum forming stationary  casting opera-
tions, if contact water is used,  it probably is evaporated and
not discharged.

Degassing Scrubber Liquor.  The purpose, variations, and limita-
tions of metal treatment technologies are described in Section
III (p.  95 ).  While the wastewater sampling program was in
progress, two of the plants visited had wet air pollution control
devices cleaning the degassing fumes.  Since that time, the plant
that was sampled replaced the wet scrubbers with  dry devices.
Only one of the 80 plants with casting operations surveyed in
this study continues to use wet air pollution controls in associ-
ation with their metal treatment operations prior to casting.
Sufficient data were not available from this plant; however, to
calculate the water use or wastewater flow of this stream.  There
have been four plants that have gone to the alternative degassing
air pollution control methods since the draft document was
written.  Eleven primary aluminum plants reported using wet air
pollution controls in their metal treatment operations.  Of
these, four provided enough information to allow  the calculation
of water use values and five gave enough data for wastewater
calculations.  This information is presented in Table V-67.

Toxic pollutant  frequency occurrence data are presented in Table
V-68.   Table V-69 summarizes the field sampling data for those
pollutants detected above analytically quantifiable levels.  This
wastewater is characterized by slightly elevated  levels of
suspended solids (<38 mg/1).

Additional Wastewater Samples

Table V-70 presents the field sampling data for all raw waste
samples not previously presented.  Most of these  samples repre-
sent combined wastewater streams  (e.g., contact cooling water and
noncontact cooling water) or streams not considered in the scope
of this regulation.

Treated Wastewater Samples

Tables V-71 through V-82 present the field sampling data for the
treated wastewater from 12 of the 20 sampled plants.  These
                               174

-------
treated wastewater data have been incorporated into the larger
data base which was used to determine the treatment effectiveness
for different control systems.  The treatability limits selected
for the aluminum forming control options are presented in Section
VII (Control and Treatment Technology)  (Table VII-21, p.  748 ).

Most of the treated wastewater streams analyzed were collected
after some form of oil separation (Streams D-15, E-8, and U-3)
and emulsion breaking process (Streams B-7, C-9, E-9, P-7, and
U-8) (see Figures V-l through V-20).  As expected,  these streams
showed lower concentrations of oil and grease (<100 mg/1) than
found in the influent raw waste streams.  In addition, one stream
(Stream B-8) was sampled after an ultrafiltration process which
removes a large percentage of the oil and grease from the raw
waste.   Also, samples collected after settling ponds, lagoons, or
clarifiers (Streams D-4, E-ll, J-6, K.-5, and Q-4) showed reduced
levels of suspended solids.  Lime and settle system effluents
(Streams D-14 and K-5) had toxic metal concentrations below the
detection limits for most of the toxic metals.

                            Section VI

                SELECTION OF POLLUTANT PARAMETERS
The Agency has studied aluminum forming wastewaters  to determine
the presence or absence  of  toxic, conventional  and selected  non-
conventional pollutants.  The toxic pollutants  and nonconven-
tional pollutants are subject to BAT effluent limitations  and
guidelines.  Conventional pollutants are considered  in establish-
ing BPT, BCT, and NSPS limitations.

One hundred and twenty-nine toxic pollutants (known  as the 129
priority pollutants) were studied pursuant to the requirements of
the Clean Water Act of 1977 (CWA).  These pollutant  parameters,
which are listed in Table VI-1, are members of  the 65 pollutants
and classes of toxic pollutants referred to as  Table 1 in Section
307(a)(1) of the CWA.

From the original list of 129 pollutants, three pollutants have
been deleted in two separate amendments to 40 CFR Subchapter N,
Part 401.  Dichlorodifluoromethane and trichlorofluoromethane
were deleted first (46 FR 2266, January 8, 1981) followed by the
deletion of bis-(chloromethyl) ether (46 FR 10723, February  4,
1981).  The Agency has concluded that deleting  these compounds
will not compromise adequate control over their discharge into
the aquatic environment  and that no adverse effects  on the
aquatic environment or on human health will occur as a result of
deleting them from the list of toxic pollutants.

Past studies by EPA and  others have identified  many  nontoxic pol-
lutant parameters useful in characterizing industrial wastewaters
and in evaluating treatment process removal efficiencies.  Cer-
tain of these and other parameters may also be  selected as reli-
able indicators of the presence of specific toxic pollutants.
For these reasons, a number of nontoxic pollutants were also
studied for the aluminum forming category.

Congress has defined the criteria for the selection  of conven-
tional pollutants (43 FR 32857 January 11, 1980).  These criteria
are:

1.  Generally those pollutants that are naturally occurring,
biodegradable;  oxygen-demanding materials, and  solids that have
characteristics similar to naturally occuring,   biodegradable sub-
stances;  or,

2.  Include those classes of pollutants that traditionally have
been the primary focus of wastewater control.
                               437

-------
The conventional pollutants considered  (total suspended solids,
oil and grease, and pH) traditionally have been studied to char-
acterize industrial wastewaters.  These parameters are especially
useful in evaluating the effectiveness of wastewater treatment
processes.

Several nonconventional pollutants were considered.  These
included aluminum, chemical oxygen demand (COD), phenols (total),
and total organic carbon (TOG).  In addition, calcium, magnesium,
alkalinity, total dissolved solids and sulfate were measured to
provide data to evaluate the cost of chemical precipitation and
sedimentation treatment of certain wastewater streams.  Of these
pollutants, only aluminum was  considered for regulation in
establishing effluent limitations guidelines, since it is the
metal being processed and is found in significant concentration
in all wastewater streams.

RATIONALE FOR SELECTION OF POLLUTANT PARAMETERS

A pollutant that was never detected, or that was never found
above its analytical quantification level, was eliminated from
consideration.  The analytical quantification level for a pollu-
tant is the minimum concentration at which that pollutant can be
reliably measured.  For the toxic pollutants in this study, the
analytical quantification levels are:  0.005 mg/1 for pesticides,
PCB's, chromium, and nickel; 0.010 mg/1 for the remaining organic
toxic pollutants and cyanide,  arsenic, beryllium, and selenium;
10 million fibers per liter (10 MFL) for asbestos; 0.020 mg/1 for
lead and silver; 0.009 mg/1 for copper; 0.002 mg/1 for cadmium;
and 0.0001 mg/1 for mercury.

The pesticide TCDD (2,3,7,8-tetrachloridibenzo-p-dioxin) was not
analyzed for because a standard sample was unavailable to the
analytical laboratories.  Samples collected by the Agency's con-
tractor were not analyzed for  asbestos.  Data on asbestos content
are available for a very small number of samples relevant to this
study as a result of the first phase of a screening program for
asbestos in a wide range of industrial categories.  Of these
samples, only a few appear to  contain asbestos at analytically
significant levels.   A verification sampling plan has not been
developed at this time.

Pollutants which were detected below levels considered achievable
by specific available treatment methods were also eliminated from
further consideration.  For the toxic metals, the chemical
precipitation, sedimentation,  and filtration technology treata-
bility values, which are presented in Section VII (Table VII-21,
                               438

-------
p.  748 ), were used.  For the toxic organic pollutants detected
above  their analytical quantification level, treatability levels
for  activated carbon technology were used.  These treatability
values  represent the most stringent treatment options considered
for  pollutant removal.  This allows for the most conservative
pollutant exclusion based on pollutants detected below treatable
levels.

Waste  streams in the aluminum forming category have been grouped
together into core and ancillary waste streams in the subcate-
gorization scheme, which has been described in Section IV. The
pollutant exclusion procedure was applied for the following:

     (1)   Rolling With Neat Oils Core Waste Streams
     (2)   Rolling With Emulsions Core Waste Streams
     (3)   Extrusion Core Waste Streams
     (4)   Forging Core Waste Streams
     (5)   Drawing With Neat Oils Core Waste Streams
     (6)   Drawing With Emulsions Or Soaps Core Waste Streams
     (7)   Ancillary Waste Streams

Toxic pollutants remaining after the application of the exclusion
process were then selected for further consideration in estab-
lishing specific regulations.

DESCRIPTION OF POLLUTANT PARAMETERS

The  following discussion addresses the pollutant parameters
detected above their analytical quantification level in any
sample  of aluminum forming wastewater.  The description of each
pollutant provides the following information:  the source of the
pollutant; whether it is a naturally occuring element, processed
metal,  or manufactured compound; general physical properties and
the  form of the pollutant; toxic effects of the pollutant in
humans  and other animals; and behavior of the pollutant in a POTW
at concentrations that might be expected from industrial
discharges.

Acenaphthene  (1).  Acenaphthene (1,2-dihydroacenaphthylene, or
1,8-ethylene-naphthalene) is a polynuclear aromatic hydrocarbon
(PAH) with molecular weight of 154 and a formula of Ci2HiQ.

Acenaphthene occurs in coal tar produced during high temperature
coking  of coal.   It has been detected in cigarette smoke and
gasoline exhaust condensates.
The pure compound is a white c
solid at room tempera-
ture with a melting range of 95 C to 97°C and a boiling range of
278°C to 280°C.  Its vapor pressure at room temperature is less
than 0.02 mm Hg.  Acenaphthene is slightly soluble in water (100
                               439

-------
mg/1), but even more  soluble  in  organic  solvents  such as  ethanol,
toluene, and chloroform.  Acenaphthene can  be  oxidized by oxygen
or ozone in the presence of certain  catalysts.   It  is stable
under laboratory conditions.

Acenaphthene is used  as a dye  intermediate,  in the  manufacture of
some plastics, and as an insecticide and fungicide.

So little research has been performed on acenaphthene that its
mammalian and human health effects are virtually  unknown.   The
water quality criterion of 0.02  mg/1 is  recommended to prevent
the adverse effects on humans  due to the organoleptic properties
of acenaphthene in water.

No detailed study of  acenaphthene behavior  in  a POTW is avail-
able.  However, it has been demonstratd  that none of the  organic
toxic pollutants studied so far  can  be broken  down  by biological
treatment processes as readily as fatty  acids,  carbohydrates,  or
proteins.  Many of the toxic  pollutants  have been investigated,
at least in laboratory-scale  studies, at concentrations higher
than those expected to be contained  by most municipal waste -
waters.  General observations  relating molecular  structure to
ease of degradation have been  developed  for all of  the toxic
organic pollutants.

The conclusion reached by study  of the limited data is that bio-
logical treatment produces little or no  degradation of acenaph-
thene.  No evidence is available for drawing conclusions  about
its possible toxic or inhibitory effect  on  POTW operation.

Its water solubility would allow acenaphthene  present in  the
influent to pass through a POTW  into the effluent.   The hydrocar-
bon character of this compound makes it  sufficiently hydrophobic
that adsorption onto  suspended solids and retention in the sludge
may also be a significant route  for  removal of acenaphthene from
the POTW.

Acenaphthene has been demonstrated to affect the  growth of plants
through improper nuclear division and polyploidal chromosome
number.  However, it  is not expected that land  application o£
sewage sludge containing acenaphthene at the low  concentrations
which are to be expectd in a POTW sludge would  result in  any
adverse effects on animals ingesting plants grown in such soil.

Benzene (4).  Benzene (CgHg)  is  a clear,  colorless  liquid
obtained mainly from petroleum feedstocks by several different
processes.  Some is recovered  from light oil obtained from coal
carbonization gases.  It boils at 80 C and has  a  vapor pressure
of 100 mm Hg at 26°C.  It is  slightly soluble  in  water (1.8 g/1
at 25°C) and it dissolves in hydrocarbon solvents.   Annual U.S.
production is three to four million  tons.

Most  of  the  benzene used  in  the  U.S.  goes  into  chemical manufac-
ture.  About half of  that  is  converted  to  ethylbenzene  which is
used  to  make styrene.   Some  benzene  is  used  in  motor fuels.

Benzene  is harmful to human  health according to numerous pub-
lished studies.  Most studies  relate  effects of inhaled benzene
vapors.  These effects  include nausea,  loss  of  muscle coordina-
tion, and excitement, followed by depression and coma.   Death is
usually  the  result of respiratory or  cardiac failure.  Two spe-
cific blood  disorders are  related to  benzene exposure.   One  of
these, acute myelogenous  leukemia, represents a carcinogenic
effect of benzene.  However,  most human exposure data is based on
exposure in  occupational  settings and benzene carcinogenisis is
not considered to be  firmly  established.

Oral administration of  benzene to laboratory animals produced
leukopenia,  a reduction in mumber of  leukocytes  in  the  blood.
Subcutaneous injection  of  benzene-oil solutions  has  produced sug-
gestive, but not conclusive,  evidence of benzene carcinogenisis.

Benzene  demonstrated teratogenic effects in  laboratory  animals,
and mutagenic effects in humans  and other  animals.

For maximum protection  of  human health  from  the  potential carcin-
ogenic effects of exposure to  benzene through ingestion of water
and contaminated aquatic organisms, the  ambient  water concentra-
tion is  zero.  Concentrations  of benzene estimated  to result in
additional lifetime cancer risk at levels  of 10"',  10~°,  and
10-5 are 0.00015 mg/1,  0.0015  mg/1, and  0.015 mg/1,
respectively.

Some studies have been  reported regarding  the behavior  of benzene
in a POTW.  Biochemical oxidation of  benzene under  laboratory
conditions,  at concentrations  of 3 to 10 mg/1, produced 24,  27,
24, and  20 percent degradation in 5,  10, 15,  and 20  days,  respec-
tively,  using unacclimated seed cultures in  fresh water.   Degra-
dation of 58, 67, 76,  and  80 percent  was produced in the  same
time periods using acclimated  seed cultures.  Other  studies  pro-
duced similar results.  Based  on these  data  and  general conclu-
sions relating molecular structure to biochemical oxidation,  it
is expected that biological treatment in a POTW  will remove  ben-
zene readily from the water.   Other reports  indicate that  most
benzene entering a POTW is removed to the  sludge and that  influ-
ent concentrations of 1 g/1 inhibit sludge digestion.   There  is
no information about possible  effects of benzene on  crops  grown
in soils  amended with sludge containing benzene.

Carbon Tetrachloride (6).   Carbon tetrachloride  (CC14),  also
called tetrachloromethane, is  a colorless  liquid produced  primar-
ily by the chlorination of hydrocarbons  - particularly  methane.
                                441

-------
Carbon tetrachlortde boils  at  77°C  and  has  a vapor pressure of 90
mm Hg at 20°C.   It is  slightly soluble  in water  (0.8 gm/1  at
25°C) and soluble in many organic solvents.   Approximately
one-third of a million tons  is produced annually in the U.S.
Carbon tetrachloride, which was displaced by  perchloroethylene as
a dry cleaning agent in the 1930's,  is used principally as  an
intermediate for production of chlorofluoromethanes  for refriger-
ants, aerosols, and blowing agents.   It  is also  used as a grain
fumigant.

Carbon tetrachloride produces a variety  of toxic effects  in
humans.  Ingestion of relatively  large quantities -  greater than
five grams - has frequently proved  fatal.  Symptoms  are burning
sensation in the mouth, esophagus,  and stomach,  followed by
abdominal pains, nausea, diarrhea,  dizziness,  abnormal  pulse,  and
coma.  When death does not occur  immediately,  liver  and kidney
damage are usually found.  Symptoms  of chronic poisoning are not
as well defined.   General fatigue,  headache,  and anxiety have
been observed, accompanied by digestive  tract  and kidney dis-
comfort or pain.

Data concerning teratogenicity and  mutagenicity  of carbon tetra-
chloride are scarce and inconclusive.  However,  carbon  tetrachlo-
ride has been demonstrated to be  carcinogenic  in laboratory
animals.  The liver was the target  organ.

For maximum protection of human health from the  potential carcin-
ogenic effects of exposure to carbon tetrachloride through inges-
tion of water and contaminated aquatic organisms,  the ambient
water concentration of zero.  Concentrations  of  carbon  tetrachlo-
ride estimated to result in additional lifetime  cancer  risk at
risk levels of 10'7, 10'6, and 10"5  are  0.000026 mg/1,
0.00026 mg/1, and 0.0026 mg/1, respectively.

Data on the behavior of carbon tetrachloride  in  a POTW  are  not
available.  Many of the toxic organic pollutants have been  inves-
tigated, at least in laboratory-scale studies, at concentrations
higher than those expected to be  found in most municipal  waste*
waters.   General observations have been  developed relating
molecular structure to ease of degradation for all of the toxic
organic pollutants.  The conclusion  reached by study of the
limited data is that biological treatment produces a moderate
degree of removal of carbon tetrachloride in  a POTW.  No  informa-
tion was found regarding the possible interference of carbon
tetrachloride with treatment processes.  Based on the water
solubility of carbon tetrachloride,  and  the vapor pressure  of
this compound, it is expected that  some  of the undegraded carbon
tetrachloride will pass through to  the POTW effluent and some
will be volatilized in aerobic processes.

Chlorobenzene  (7).   Chlorobenzene  (C^H^Cl),  also called mono-
chlorobenzene  is  a  clear,  colorless,  liquid  manufactured by the
liquid phase chlorination  of  benzene  over a  catalyst.   It boils
at  132°C and has  a  vapor pressure  of  12.5 mm Hg at 25°C.  It is
almost insoluble  in water  (0.5  g/1 at 30 C),  but dissolves in
hydrocarbon solvents.   U.S. annual production is near  150,000
tons.

Principal uses of Chlorobenzene are as  a solvent and as an inter-
mediate for dyes  and pesticides.   Formerly it was used as an
intermediate for  DDT production, but  elimination of production of
that compound  reduced  annual  U.S.  production  requirements for
Chlorobenzene  by  half.

Data on the threat  to  human health posed by  Chlorobenzene are
limited in number.   Laboratory  animals,  administered large doses
of  Chlorobenzene  subcutaneously, died as a result of central
nervous system depression.  At  slightly  lower dose rates, animals
died of liver  or  kidney damage.  Metabolic disturbances occurred
also.  At even lower dose  rates  of orally administered chloroben-
zene similar effects were  observed, but  some  animals survived
longer than at higher  dose rates.   No studies have been reported
regarding evaluation of the teratogenic,  mutagenic,  or carcino-
genic potential of  Chlorobenzene.

For the prevention  of  adverse effects due to  the organoleptic
properties of  Chlorobenzene in  water  the recommended criterion is
0.020 rag/1.

Only limited data are  available  on which to base conclusions
about the behavior  of  Chlorobenzene in a POTW.   Laboratory
studies of the biochemical oxidation  of  Chlorobenzene  have been
carried out at concentrations greater than those expected to
normally be present  in  POTW influent.  Results  showed  the extent
of  degradation to be 25, 28, and 44 percent after 5, 10,  and 20
days, respectively.  In another, similar study  using a phenol-
adapted culture 4 percent  degradation was  observed after 3 hours
with a solution containing 80 mg/1.   On  the basis  of these
results and general  conclusions  about the  relationship of molec-
ular structure to biochemical oxidation,  it is  concluded that
Chlorobenzene remaining intact  is  expected to volatilize from the
POTW in aeration processes.  The estimated half-life of chloro-
benzene in water based  on water  solubility, vapor pressure and
molecular weight is  5.8 hours.

1,1,1-Trichloroethane  (11).  1,1,1-Trichloroethane  is  one of the
two possible trichlorethanes.   It  is  manufactured  by hydrochlori-
nating vinyl chloride to 1,1-dichloroethane which  is then chlori-
nated to the desired product.   1,1,1-Trichloroethane is  a liquid
at room temperature with a vapor pressure  of  96 mm Hg  at  20°C and
a boiling point of  74°C.  Its formula is  CC13CH3.   It  is
                               443

-------
slightly soluble in water  (0.48 g/1) and is very soluble in
organic solvents.  U.S. annual production is greater than one-
third of a million tons.

1,1,1-Trichloroethane is used as an industrial solvent and
degreasing agent.

Most human toxicity data for 1,1,1-trichloroethane relates to
inhalation and dermal exposure routes.  Limited data are avail-
able for determining toxicity of ingested 1,1,1-trichloroethane,
and those data are all for the compound itself, not solutions in
water.  No data are available regarding its toxicity to fish and
aquatic organisms.  For the protection of human health from the
toxic properties of 1,1,1-trichloroethane ingested through the
comsumption of water and fish, the ambient water criterion is
15.7 mg/1.   The criterion is based on bioassays for possible
carcinogenicity.

No detailed study of 1,1,1-trichloroethane behavior in a POTW is
available.   However, it has been demonstrated that none of the
toxic organic pollutants of this type can be broken down by bio-
logical treatment processes as readily as fatty acids, carbohy-
drates, or proteins.

Biochemical oxidation of many of the toxic organic pollutants has
been investigated, at least in laboratory scale studies, at con-
centrations higher than commonly expected in municipal waste-
water.  General observations relating molecular structure to ease
of degradation have been developed for all of these pollutants.
The conclusion reached by study of the limited data is that
biological treatment produces a moderate degree of degradation of
1,1,1-trichloroethane.  No evidence is available for drawing con-
clusions about its possible toxic or inhibitory effect on POTW
operation.   However, for degradation to occur, a fairly constant
input of the compound would be necessary.

Its water solubility would allow 1,1,1-trichloroethane, present
in the influent and not biodegradable, to pass through a POTW
into the effluent.  One factor which has received some attention,
but no detailed study, is the volatilization of the lower molecu-
lar weight organics from a POTW.  If 1,1,1-trichloroethane is not
biodegraded, it will volatilize during aeration processes in the
POTW.

1,1-Dichloroethane (13) .  1,1-Dichloroethane, also called ethyli-
dene dichloride and ethylidene chloride, is a colorless liquid
manufactured by reacting hydrogen chloride with vinyl chloride in
1,1-dichloroethane solution in the presence of a catalyst.  How-
ever, it is reportedly not manufactured commercially in the U.S.
                                444

-------
1,1-Dichloroethane boils at 57°C and has  a vapor  pressure  of  182
mm Hg at 20°C.  It is  slightly  soluble  in water  (5.5  g/1 at 20°C)
and very soluble  in organic solvents.

1,1-Dichloroethane is  used as an extractant  for heat-sensitive
substances and as a solvent for rubber  and silicone grease.

1,1-Dichloroethane is  less toxic than its isomer  (1,2-dichloro-
ethane) , but  its use as an anesthetic has been discontinued
because of marked excitation of the heart.   It causes  central
nervous system depression in humans.  There  are insufficient  data
to derive water quality criteria for 1,1-dichloroethane.

Data on the behavior of 1,1-dichloroethane in a POTW  are not
available.  Many of the toxic organic pollutants  have  been
investigated, at least in laboratory scale studies, at  concen-
trations higher than those expected to  be contained by  most
municipal wastewaters.  General observations have been  developed
relating molecular structure to ease of degradation for all of
the toxic organic pollutants.  The conclusion reached  by study of
the limited data is that biological treatment produces  only a
moderate removal of 1,1-dichloroethane  in a POTW  by degradation.

The high vapor pressure of 1,1-dichloroethane is  expected  to
result  in volatilization of some of the compound  from  aerobic
processes in  a POTW.   Its water solubility will result  in  some of
the 1,1-dichloroethane which enters the POTW leaving  in the
effluent from the POTW.

1,1,2-Trichloroethane  (14).  1,1,2-Trichloroethane is  one  of  the
two possible  trichloroethanes and is sometimes called  ethane  tri-
chloride or vinyl trichloride.  It is used as a solvent for fats,
oils, waxes,  and resins, in the manufacture  of 1,1-dichloro-
ethylene, and as an intermediate in organic  synthesis.

1,1,2-Trichloroethane  is a clear, colorless  liquid at  room tem-
perature with a vapor  pressure of 16.7  mm Hg at 20 C,  and  a boil-
ing point of 113°C.  It is insoluble in water and very  soluble in
organic solvents.  The formula is CHC12CH2C1.

Human toxicity data for 1,1,2-trichloroethane does not  appear in
the literature.  The compound does produce liver  and kidney dam-
age in  laboratory animals after intraperitoneal administration.
No literature data was found concerning teratogenicity  or  muta-
genicity of 1,1,2-trichloroethane.  However, mice treated  with
1,1,2-trichloroethane  showed increased  incidence  of hepatocellu-
lar carcinoma.  Although bioconcentration factors are not  avail-
able for 1,1,2-trichloroethane in fish  and other  freshwater
aquatic organisms, it  is concluded on the basis of octanol-water
partition coefficients that bioconcentration does occur.
                               445

-------
For the maximum protection of human health  from the potential
carcinogenic effects of exposure to 1,1,2-trichloroethane through
ingestion of water and contaminated aquatic organisms,  the ambi-
ent water concentration is zero.  Concentrations of this compound
estimated to result in additional lifetime  cancer  risks at risk
levels of 10-', 10'°, and 10"5 are Q.00006  mg/1, 0.0006
mg/1, and 0.006 mg/1, respectively.   If  contaminated aquatic
organisms alone are consumed, excluding the consumption of water,
the water concentration should be less  than 0.418  mg/1  to keep
the increased lifetime cancer risk below  10~->.  Available data
show that adverse effects on aquatic  life occur at concentrations
higher than those cited for human health  risks.

No detailed study of 1,1,2-trichloroethane  behavior in  a POTW is
available.  However, it is reported that  small amounts  are formed
by chlorination processes and that this compound persists in the
environment (greater than two years) and  it is not biologically
degraded.  This information is not completely consistant with the
conclusions based on laboratory scale biochemical  oxidation
studies and relating molecular structure  to ease of degradation.
That study concluded that biological treatment in  a POTW will
produce moderate removal of 1,1,2-trichloroethane.

The lack of water solubility and the relatively high vapor
pressure may lead to removal of this compound from a POTW by
volatilization.

2,4,6-Trichlorpphenol (21).  2,4,6-Trichlorophenol
(Cl^Cfcl^OH, abbreviated here to 2,4,6-TCP)  is a colorless,
crystalline solid at room temperature.  It  is prepared by the
direct chlorination of phenol.  2,4,6-TCP melts at 68°C and is
slightly soluble in water (0.8 gm/1 at 25°C).  This phenol does
not produce a color with 4-aminoantipyrene, and therefore does
not contribute to the nonconventional pollutant parameter "Total
Phenols."  No data were found on production volumes.

2,4,6-TCP is used as a fungicide, bactericide, glue and wood pre-
servative, and for antimildew treatment.  It is also used for the
manufacture of 2,3,4,6-tetrachlorophenol  and pentachlorophenol.

No data were found on human toxicity effects of 2,4,6-TCP.
Reports of studies with laboratory animals  indicate that
2,4,6-TCP produced convulsions when injected interperitoneally.
Body temperature was elevated also.  The  compound  also produced
inhibition of ATP production in isolated  rat liver mitochondria,
increased mutation rates in one strain of bacteria, and produced
a genetic change in rats.   No studies on  teratogenicity were
found.  Results of a test for carcinogenicity were inconclusive.
                               446

-------
For  the prevention  of  adverse  effects  due  to  the  organoleptic
properties  of 2,4,6-trichlorophenol  in water,  the water  quality
criterion  is 0.100  mg/1.

Although no data were  found  regarding  the  behavior  of  2,4,6-TCP
in a POTW,  studies  of  the biochemical  oxidation of  the compound
have been  made  at laboratory scale at  concentrations higher  than
those normally  expected in municipal wastewaters.   Biochemical
oxidation  of 2,4,6-TCP at 100  mg/1 produced 23 percent degrada-
tion using  a phenol-adapted  acclimated seed culture.   Based  on
these results,  biological treatment  in a POTW  is  expected  to pro-
duce a moderate degree of degradation.  Another study  indicates
that 2,4,6-TCP  may  be  produced in a POTW by chlorination of
phenol during normal chlorination treatment.

Para-chloro-meta-cresol (22).   Para-chloro-meta-cresol
(CICyHgOH)  is thought  to be  a  4-chloro-3-methyl~phenol
(4-chloro-meta-cresol, or 2-chloro-5-hydroxy-toluene), but is
also used by some authorities  to refer to  6-chloro-3-methyl-
phenol (6-chloro-meta-cresol,  or 4-chloro-3-hydroxy-toluene),
depending on whether the chlorine is considered to  be  para to the
methyl or to the hydroxy group.  It is assumed for  the purposes
of this document that  the subject compound is  2-chloro-5-hydroxy-
toluene.  This  compound is a colorless crystalline  solid melting
at 66 to 68°C.  It  is  slightly soluble in  water (3.8 gm/1) and
soluble in  organic  solvents.   This phenol  reacts with  4-amino-
antipyrene  to give  a colored product and therefore  contributes to
the  nonconventional pollutant  parameter designated  "Total
Phenols."  No information on manufacturing methods  or  volumes
produced was found.

Para-chloro-meta cresol (abbreviated here  as PCMC)  is  marketed as
a microbicide,  and was proposed as an  antiseptic and disinfectant
more than 40 years  ago.  It  is used in glues,  gums, paints,  inks,
textiles, and leather goods.   PCMC was found in raw wastewaters
from the die casting quench  operation  from one subcategory of
foundry operations.

Although no human toxicity data are available  for PCMC,  studies
on laboratory animals have demonstrated that this compound is
toxic when  administered subcutaneously and intravenously.  Death
was  preceded by severe muscle  tremors.   At high dosages kidney
damage occurred.  On the other hand,  an unspecified isomer of
chlorocresol,  presumed to be PCMC, is used at a concentration of
0.15 percent to preserve muicous heparin,  a natural product
administered intravenously as  an anticoagulant.  The report  does
not  indicate the total amount  of PCMC  typically received.  No
information was found regarding possible teratogenicity, or
carcinogenicity of PCMC.
                               447

-------
Two reports indicate that PCMC undergoes degradation in biochemi-
cal oxidation treatments carried out at concentrations higher
than are expected to be encountered in POTW influents.  One study
showed 50 percent degradation in 3.5 hours when a phenol-adapted
acclimated seed culture was used with a solution of 60 mg/1 PCMC.
The other study showed 100 percent degradation of a 20 mg/1 solu-
tion of PCMC in two weeks in an aerobic activated sludge test
system.  No degradation of PCMC occurred under anaerobic con-
ditions .

Chloroform (23).  Chloroform also called trichloromethane, is a
colorless liquid manufactured commercially by chlorination of
methane.  Careful control of conditions maximizes chloroform pro-
duction, but other products must be separated.  Chloroform boils
at 61°C and has a vapor pressure of 200 mm Hg at 25°C.  It is
slightly soluble in water (8.22 g/1 at 20°C) and readily soluble
in organic solvents.

Chloroform is used as a solvent and to manufacture refrigerants,
Pharmaceuticals, plastics, and anesthetics.  It is seldom used as
an anesthetic.

Toxic effects of chloroform on humans include central nervous
system depression, gastrointestinal irritation, liver and kidney
damage and possible cardiac sensitization to adrenalin.  Carcino-
genicity has been demonstrated for chloroform on laboratory
animals.

For the maximum protection of human health from the potential
carcinogenic effects of exposure to chloroform through ingestion
of water and contaminated aquatic organisms, the ambient water
concentration is zero.  Concentrations of chloroform estimated to
result in additional lifetime cancer risks at the levels of
10-/, iQ-6^ and iQ-5 were 0.000021 mg/1, 0.00021 mg/1, and
0.0021 mg/1, respectively.

No data are available regarding the behavior of chloroform in a
POTW.  However, the biochemical oxidation of this compound was
studied in one laboratory scale study at concentrations higher
than those expected to be contained by most municipal waste-
waters.  After 5, 10, and 20 days no degradation of chloroform
was observed.  The conclusion reached is that biological treat-
ment produces little or no removal by degradation of chloroform
in a POTW.

The high vapor pressure of chloroform is expected to result in
volatilization of the compound from aerobic treatment steps in a
                               448

-------
POTW.  Remaining  chloroform  is  expected  to pass  through  into  the
POTW effluent.

2-Chlorophenol  (24).  2-Chlorophenol  (C1C6H40H), also  called
ortho-chlorophenol,  is  a  colorless  liquid at  room temperature,
manufactured by direct  chlorination of phenol  followed by  distil-
lation to  separate  it from the  other  principal product,  4-chloro-
phenol.  2-Chlorophenol solidifies  below 7°C  and boils at  176°C.
It is soluble in  water  (28.5 gm/1 at  20°C) and soluble in  several
types of organic  solvents.  This phenol  gives a strong color with
4-aminoantipyrene and therefore contributes to the nonconven-
tional pollutant  parameter "Total Phenols."  Production  statis-
tics could not be found.  2-Chlorophenol is used almost
exclusively as a  chemical intermediate in the production of
pesticides and dyes.  Production of some phenolic resins uses
2-chlorophenol.

Very few data are available on which  to  determine the  toxic
effects of 2-chlorophenol on humans.  The compound is  more toxic
to laboratory mammals when administered  orally than when adminis-
tered subcutaneously or intravenously.   This  affect is attributed
to the fact that  the compound is almost  completely in  the un-ion-
ized state at the low pH of the stomach  and hence is more readily
absorbed into the body.   Initial symptoms are restlessness and
increased respiration rate, followed  by  motor weakness and con-
vulsions induced  by noise or touch.   Coma follows.  Following
lethal doses, kidney, liver, and intestinal damage were  observed.
No studies were found which addressed the teratogenicity or
mutagenicity of 2-chlorophenol.  Studies of 2-chlorophenol as a
promoter of carcinogenic activity of  other carcinogens were
conducted by dermal application.  Results do not bear  a  deter-
minable relationship to results of oral  administration studies.

For the prevention of adverse effects due to the organoleptic
properties of 2-chlorophenol in water, the criterion is  0.0003
mg/1.

Data on the behavior of 2-chlorophenol in a POTW are not avail-
able.   However, laboratory scale studies have been conducted at
concentrations higher than those expected to be found  in munici-
pal wastewaters.  At 1 mg/1 of 2-chlorophenol, an acclimated
culture produced 100 percent degradation by biochemical  oxidation
after 15 days.  Another study showed 45, 70,  and 79 percent
degradation by biochemical oxidation after 5, 10, and  20 days,
respectively.  The conclusion reached by the study of  these
limited data, and general observations on all toxic organic
pollutants relating molecular structure  to ease of biochemcial
oxidation,  is that 2-chlorophenol is removed to a high degree or
                               449

-------
completely by biological treatment in a POTW.  Undegraded
2-chlorophenol is expected to pass through a POTW into the efflu-
ent because of the water solubility.  Some 2-chlorophenol is also
expected to be generated by chlorination treatments of POTW
effluents containing phenol,

1,1-Dichloroethylene (29).  1,1-Dichloroethylene (1,1-DCE), also
called vinylidene chloride, is a clear colorless liquid manufac-
tured by dehydrochlorination of 1,1,2-trichloroethane.  1,1-DCE
has the formula CC12CH2-  It has a boiling point of 32°C, and
a vapor pressure of 591 mm Hg at 25°C.  1,1-DCE is slightly solu-
ble in water (2.5 mg/1) and is soluble in many organic solvents.
U.S. production is in the range of hundreds of thousands of tons
annually.

1,1-DCE is used as a chemical intermediate and for copolymer
coatings or films.  It may enter the wastewater of an industrial
facility as the result of decomposition of 1,1,1-trichloro-
ethylene used in degreasing operations, or by migration from
vinylidene chloride copolymers exposed to the process water.
Human toxicity of 1,1-DCE has not been demonstrated; however, it
is a suspected human carcinogen.  Mammalian toxicity studies have
focused on the liver and kidney damage produced by 1,1-DCE.
Various changes occur in those organs in rats and mice ingesting
1,1-DCE.

For the maximum protection of human health from the potential
carcinogenic effects of exposure to 1,1-dichloroethylene through
ingestion of water and contaminated aquatic organisms, the ambi-
ent water concentration is zero.  The concentration of 1,1-DCE
estimated to result in an additional lifetime cancer risk of 1 in
100,000 is 0.0013 mg/1.

Under laboratory conditions, dichloroethylenes have been shown to
be toxic to fish.  The primary effect of acute toxicity of the
dichloroethylenes is depression of the central nervous system.
The octanol/water partition coefficident of 1,1-DCE indicates it
should not accumulate significantly in animals.

The behavior of 1,1-DCE in a POTW has not been studied.  However,
its very high vapor pressure is expected to result in release of
significant percentages of this material to the atmosphere in any
treatment involving aeration.  Degradation of dichloroethylene in
air is reported to occur, with a half-life of eight weeks.

Biochemical oxidation of many of the toxic organic pollutants has
been investigated in laboratory scale studies at concentrations
higher than would normally be expected in municipal wastewaters.
General observations relating molecular structure to ease of

-------
degradation have been developed for all of these pollutants.  The
conclusion reached by study of the limited data is that biologi-
cal treatment produces little or no degradation of 1,1-dichloro-
ethylene.  No evidence is available for drawing conclusions about
the possible toxic or inhibitory effect of 1,1-DCE on POTW opera-
tion.   Because of water solubility, 1,1-DCE which is not volatil-
ized or degraded is expected to pass through a POTW.  Very little
1,1-DCE is expected to be found in sludge from a POTW.

1,2-trans-Dichloroethylene (30).  1,2-Dichloroethylene (1,2-
trans-DCE) is a clear, colorless liquid with the formula
CHC1CHC1.  1,2-trans-DCE is produced in mixture with the cis-
isomer by chlorination of acetylene.  The cis-isomer has dis-
tinctly different physical properties.  Industrially, the mixture
is used rather than the separate isomers.  1,2-trans-DCE has a
boiling point of 48°C, and a vapor pressure of 234 mm Hg at 25°C.

The principal use of 1,2-dichloroethylene (mixed isomers) is to
produce vinyl chloride.  It is used as a lead scavenger in gaso-
line,  general solvent, and for synthesis of various other organic
chemicals.  When it is used as a solvent, 1,2-trans-DCE can enter
wastewater streams.

Although 1,2-trans-PCE is thought to produce fatty degeneration
of mammalian liver, there are insufficient data on which to base
any ambient water criterion.

In the reported toxicity test of 1,2-trans-DCE on aquatic life,
the compound appeared to be about half as toxic as the other
dichloroethylene (1,1-DCE) on the toxic pollutants list.

The behavior of 1,2-trans-DCE in a POTW has not been studied.
However, its high vapor pressure is expected to result in release
of a significant percentage of this compound to the atmosphere in
any treatment involving aeration.  Degradation of the dichloro-
ethylenes in air is reported to occur, with a half-life of eight
weeks.

Biochemical oxidation of many of the toxic organic pollutants has
been investigated in laboratory scale studies at concentrations
higher than would normally be expected in municipal wastewaters.
General observations relating molecular structure to ease of
degradation have been developed for all of these pollutants.  The
conclusion reached by the study of the limited data is that
biochemical oxidation produces little or no degradation of
1,2-trans-dichloroethylene.   No evidence is available for drawing
conclusions about the possible toxic or inhibitory effect of
1,2-trans-dichloroethylene on POTW operation.   It is expected
that its low molecular weight and degree of water solubility will
                               451

-------
result in 1,2-trans-DCE passing through a POTW  to the effluent if
it is not degraded or volatilized.  Very little 1,2-trans-DCE is
expected to be found in sludge from a POTW.

2,4-Dimethylphenol (34).  2,4-Dimethylphenol  (2,4-DMP), also
called 2,4-xylenol, is a colorless, crystalline solid at room
temperature (25°C), but melts at 27°C to 28°C.  2,4-DMP is
slightly soluble in water and, as a weak acid,  is soluble in
alkaline solutions.  Its vapor pressure is less than 1 mm Hg at
room temperature.

2,4-DMP is a natural product, occurring in coal and petroleum
sources.  It is used commercially as an intermediate for manufac-
ture of pesticides, dye stuffs, plastics and  resins, and surfac-
tants.  It  is found in the water runoff from  asphalt surfaces.
It can find its way into the wastewater of a  manufacturing plant
from any of several adventitious sources.

Analytical procedures specific to this compound are used for its
identification and quantification in wastewaters.  This compound
does not contribute to "Total Phenols" determined by the
4-aminoantipyrene method.

Three methylphenol isomers (cresols) and six  dimethylphenol
isomers (xylenols) generally occur together in  natural products,
industrial processes, commercial products, and phenolic wastes.
Therefore, data are not available for human exposure to 2,4-DMP
alone.  In addition to this, most mammalian tests for toxicity of
individual dimethylphenol isomers have been conducted with
isomers other than 2,4-DMP.

In general, the mixtures of phenol, methylphenols, and dimethyl-
phenols contain compounds which produced acute  poisoning in
laboratory animals.  Symptoms were difficult  breathing, rapid
muscular spasms, disturbance of motor coordination, and asym-
metrical body position.  In a 1977 National Academy of Science
publication the conclusion was reached that,  "In view of the
relative paucity of data on the mutagenicity, carcinogenic!ty,
teratogenicity, and long term oral toxicity of  2,4-dimethyl-
phenol, estimates of the effects of chronic oral exposure at low
levels cannot be made with any confidence."   No ambient water
quality criterion can be set at this time.  In  order to protect
public health, exposure to this compound should be minimized as
soon as possible.

Toxicity data for fish and freshwater aquatic life are limited;
however, in reported studies of 2,4-dimethylphenol at concen-
trations as high as 2 mg/1 no adverse effects were observed.
                               452

-------
The behavior of 2,4-DMP in a POTW has not been  studied.  As  a
weak acid, its behavior may be somewhat dependent on the pH  of
the influent to the POTW.  However, over the normal limited  range
of POTW pH, little effect of pH would be expected.

Biological degradability of 2,4-DMP as determined in one study,
showed 94.5 percent removal based on chemical oxygen demand
(COD).  Thus, substantial removal is expected for this compound.
Another study determined that persistance of 2,4-DMP in the  envi-
ronment is low, and thus any of the compound which remained  in
the sludge or passed through the POTW into the  effluent would be
degraded within moderate length of time (estimated as two months
in the report) .
2 ,4-Dinltrotoluene (35) .  2 ,4-Dinitrotoluene [ (l^^C^HACH^] , a
yellow crystalline compound,  is manufactured as a coproduct with
the 2,6-isomer by nitration of nitrotoluene.   It melts at 71°C.
2 ,4-Dinitrotoluene is insoluble in water (0.27 g/1 at 22°C) and
soluble in a number of organic solvents.  Production data for the
2,4-isomer alone are not available.  The 2,4-and 2,6-isomers are
manufactured in an 80:20 or 65:35 ratio, depending on the process
used.  Annual U.S. commercial production is about 150 thousand
tons of the two isomers.  Unspecified amounts  are produced by the
U.S. government and further nitrated to trinitrotoluene (TNT) for
military use.  The major use of the dinitrotoluene mixture is for
production of toluene diisocyanate used to make polyur ethanes.
Another use is in production of dyestuffs.

The toxic effect of 2 ,4-dinitrotoluene in humans is primarily
methemoglobinemia (a blood condition hindering oxygen transport
by the blood).  Symptoms depend on severity of the disease, but
include cyanosis, dizziness,  pain in joints, headache, and loss
of appetite in workers inhaling the compound.  Laboratory animals
fed oral doses of 2 ,4-dinitrotoluene exhibited many of the same
symptoms.   Aside from the effects in red blood cells, effects are
observed in the nervous system and testes.

Chronic exposure to 2 ,4-dinitrotoluene may produce liver damage
and reversible anemia.  No data were found on  teratogenicity of
this compound.  Mutagenic data are limited and are regarded as
confusing.  Data resulting from studies of carcinogenicity of
2 ,4-dinitrotoluene point to a need for further testing for this
property.

For the maximum protection of human health from the potential
carcinogenic effects of exposure to 2 ,4-dinitrotoluene through
ingestion of water and contaminated aquatic organisms, the ambi-
ent water concentration is zero.   Concentrations  of 2,4-
dinitrotoluene estimated to result in additional lifetime cancer
                               453

-------
risk at risk levels of 1CT7, 10'6, and 1Q5 are 0.0074 mg/1,
0.074 mg/1, and 0.740 mg/1, respectively.

Data on the behavior of 2,4-dinitrotoluene in a POTW are not
available.  However, biochemical oxidation of 2,4-dinitrophenol
was investigated on a laboratory scale.  At 100 mg/1 of 2,4-
dinitrotoluene, a concentration considerably higher than that
expected in municipal wastewaters, biochemical oxidation by an
acclimated, phenol-adapted seed culture produced 52 percent
degradation in three hours.  Based on this limited information
and general observations  relating molecular structure to ease of
degradation for all the toxic organic pollutants, it was con-
cluded that biological treatment in a POTW removes 2,4-dinitro-
toluene to a high degree  or completely.  No information is
available regarding possible interference by 2,4-dinitrotoluene
in POTW treatment processes, or on the possible detrimental
effect on sludge used to  ammend soils in which food crops are
grown.

Ethylbenzene (38).  Ethylbenzene is a colorless, flammable liquid
manufactured commercially from benzene and ethylene.  Approxi-
mately half of the benzene used in the U.S. goes into the manu-
facture of more than three million tons of ethylbenzene annually.
Ethylbenzene boils at 136°C and has a vapor pressure of 7 mm Hg
at 20°C.  It is slightly  soluble in water  (0.14 g/1 at 15°C) and
is very soluble in organic solvents.

About 98 percent of the ethylbenzene produced in the IKS. goes
into the production of styrene, much of which is used in the
plastics and synthetic rubber industries.  Ethylbenzene is a con-
stituent of xylene mixtures used as diluents in the paint indus-
try, agricultural insecticide sprays, and gasoline blends.

Although humans are exposed to ethylbenzene from a variety of
sources in the environment, little information on effects of
ethylbenzene in man or animals is available.  Inhalation can
irritate eyes, affect the respiratory tract, or cause vertigo.
In laboratory animals ethylbenzene exhibited low toxicity.  There
are no data available on  teratogenicity, mutagenicity, or car-
cinogenicity of ethylbenzene.

Criteria are based on data derived from inhalation exposure
limits.  For the protection of human health from the toxic prop-
erties of ethylbenzene ingested through water and contaminated
aquatic organisms, the ambient water quality criterion is 1.1
mg/1.
                               454

-------
The behavior  of  ethylbenzene  in  a POTW has  not been  studied  in
detail.  Laboratory  scale  studies of  the biochemical  oxidation  of
ethylbenzene  at  concentrations greater than would  normally be
found in municipal wastewaters have demonstrated varying  degrees
of degradation.  In  one  study with phenol-acclimated  seed
cultures, 27  percent degradation was  observed in a half day  at
250 mg/1 ethylbenzene.   Another  study at unspecified  conditions
showed 32, 38, and 45 percent degradation after 5, 10, and 20
days, respectively.  Based on these results and general observa-
tions relating molecular structure of degradation, the conclu-
sion is reached  that biological  treatment produces only mod-
erate removal of ethylbenzene in a POTW by  degradation.

Other studies suggest that most of the ethybenzene entering  a
POTW is removed  from the aqueous stream to  the sludge.  The
ethylbenzene  contained in the sludge  removed from the POTW may
volatilize.

Fluoranthene  (39) *  Fluoranthene (1 ,2-benzacenaphthene) is one of
the compounds called polynuclear aromatic hydrocarbons (PAH).  A
pale yellow solid at room temperature, it melts at 111 C  and has
a negligible vapor pressure at 25°C.  Water solubility is low
(0.2 mg/1).  Its molecular formula is
Fluoranthene, along with many other PAH's, is found throughout
the environment.  It is produced by pyrolytic processing of
organic raw materials, such as coal and petroleum, at high tem-
perature (coking processes).  It occurs naturally as a product of
plant biosyntheses.  Cigarette smoke contains fluoranthene.
Although it is not used as the pure compound in industry, it has
been found at relatively higher concentrations (0.002 mg/1) than
most other PAH's in at least one industrial effluent.  Further-
more, in a 1977 EPA survey to determine levels of PAH in U.S.
drinking water supplies, none of the 110 samples analyzed showed
any PAH other than fluoranthene.

Experiments with laboratory animals indicate that fluoranthene
presents a relatively low degree of toxic potential from acute
exposure, including oral administration.  Where death occurred,
no information was reported concerning target organs or specific
cause of death.

There is no eptdemiological evidence to prove that PAH in
general, and fluoranthene, in particular, present in drinking
water are related to the development of cancer.  The only studies
directed toward determining carcinogenicity of fluoranthene have
been skin tests on laboratory animals.   Results of these tests
show that fluoranthene has no activity as a complete carcinogen
(i.e.,  an agent which produces cancer when applied by itself),
                               455

-------
but exhibits significant cocarcinogenicity  (i.e.,  in combination
with a carcinogen, it increases the carcinogenic activity).

Based on the limited animal study data, and following an estab-
lished procedure» the ambient water quality criterion for  fluor-
anthene alone  (not in combination with other PAH)  is determined
to be 200 mg/1 for the protection of human health  from its toxic
properties.

There are no data on the chronic effects of fluoranthene on
freshwater organisms.  One saltwater invertebrate  shows chronic
toxicity at concentrations below 0.016 mg/1.  For  some fresh-
water fish species the concentrations producing acute toxicity
are substantially higher, but data are very limited.

Results of studies of the behavior of fluoranthene in conven-
tional sewage treatment processes found in a POTW  have been
published.  Removal of fluoranthene during primary sedimentation
was found to be 62 to 66 percent (from an initial  value of
0.00323 to 0.04435 mg/1 to a final value of 0.00122 to 0.0146
mg/1), and the removal was 91 to 99 percent (final values  of
0.00028 to 0.00026 mg/1) after biological purification with
activated sludge processes.

A review was made of data on biochemical oxidation of many of the
toxic organic pollutants investigated in laboratory scale  studies
at concentrations higher than would normally be expected in
municipal wastewaters.  General observations relating molecular
structure to ease of degradation have been developed for all of
these pollutants.   The conclusion reached by study of the  limited
data is that biological treatment produces little  or no degrada-
tion of fluoranthene.  The same study, however, concludes  that
fluoranthene would be readily removed by filtration and oil-water
separation and other methods which rely on water insolubility, or
adsorption on other particulate surfaces.  This latter conclusion
is supported by the previously cited study showing significant
removal by primary sedimentation.

No studies were found to give data on either the possible  inter-
ference of fluoranthene with POTW operation, or the persistance
of fluoranthene in sludges or POTW effluent waters.  Several
studies have documented the ubiquity of fluoranthene in the envi-
ronment and it cannot be readily determined if this results from
persistence of anthropogenic fluoranthene or the replacement of
degraded fluoranthene by natural processes such as biosynthesis
in plants.

Methylene Chloride (44).  Methylene chloride, also called  dichlo-
romethane (CH2C12)> is a colorless liquid manufactured by
                               456

-------
chlorination  of methane  or methyl  chloride  followed  by  separation
from the higher chlorinated methanes  formed  as  coproducts.
Methylene chloride boils at 40°C,  and has a  vapor  pressure  of 362
mm Hg at 20°C.  It is slightly soluble  in water (20  g/1 at  20°C)S
and very soluble  in organic solvents.   U.S.  annual production is
about 250,000 tons.

Methylene chloride is a  common industrial solvent  found in
insecticides, metal cleaners, paint, and paint  and varnish
removers.

Methylene chloride is not generally regarded as highly toxic to
humans.  Most human toxicity data  are for exposure by inhalation.
Inhaled methylene chloride acts as a central nervous system
depressant.  There is also evidence that the compound causes
heart failure when large amounts are inhaled.

Methylene chloride does  produce mutation in  tests  for this
effect.  In addition, a  bioassay recognized  for its  extremely
high sensitivity to strong and weak carcinogens produced results
which were marginally significant.  Thus potential carcinogenic
effects of methylene chloride are not confirmed or denied,  but
are under continuous study.  Difficulty in conducting and inter-
preting the test results from the low boiling point  (40°C)  of
methylene chloride which increases the  difficulty  of maintaining
the compound in growth media during incubation  at  37 C; and from
the difficulty of removing all impurities, some of which might
themselves be carcinogenic.

For the protection of human health from the  toxic  properties of
methylene chloride ingested through water and contaminated
aquatic organisms, the ambient water criterion  is  0.002 mg/1.
The behavior of methylene chloride in a POTW has not been studied
in any detail.  However, the biochemical oxidation of this  com-
pound was studied in one laboratory scale study at concentrations
higher than those expected to be contained by most municipal
wastewaters.  After five days no degradation of methylene chlo-
ride was observed.  The  conclusion reached is that biological
treatment produces little or no removal by degradation of
methylene chloride in a POTW.

The high vapor pressure  of methylene chloride is expected to
result in volatilization of the compound from aerobic treatment
steps in a POTW.   It has been reported that  methylene chloride
inhibits anerobic processes in a POTW.  Methylene  chloride  that
is not volatilized in the POTW is expected to pass through  into
the effluent.

-------
Isophorone  (54).  Isophorone is an industrial chemical produced
at a level  of tens of millions of pounds annually in the U.S.
The chemical name for isophorone is 3,5,5-trimethyl-2-cyclohexen-
1-one and it is also known as trimethyl cyclohexanone and
isoacetophorone.  The formula is 0^5(0113)30.  Normally,
it is produced as the gamma isomer; technical grades contain
about 3 percent of the beta isomer (3,5,5-trimethyl-3-cyclohexen-
1-one).  The pure gamma isomer is a water-white  liquid, with
vapor pressure less than 1 mm Hg at room temperature, and a
boiling point of 215.2 C.  It has a camphor- or  peppermint-like
odor and yellows upon standing.  It is  slightly  soluble (12 mg/1)
in water and dissolves in fats and oils.

Isophorone  is synthesized from acetone and is used commercially
as a solvent or cosolvent for finishes, lacquers, polyvinyl and
nitrocellulose resins, pesticides, herbicides, fats, oils, and
gums.  It is also used as a chemical  feedstock.

Because isophorone is an industrially used solvent, most toxicity
data are for inhalation exposure.  Oral administration to labora-
tory animals in two different studies revealed no acute or
chronic effects during 90 days, and no hematological or patholog-
ical abnormalities were reported.  Apparently, no studies have
been completed on the carcinogenicity of isophorone.

Isophorone  does undergo bioconcentration in the  lipids of aquatic
organisms and fish.

Based on subacute data, the ambient water quality criterion for
isophorone  ingested through consumption of water and fish is set
at 460 mg/1 for the protection of human health from its toxic
properties.

Studies of  the effects of isophorone on fish and aquatic organ-
isms reveal relatively low toxicity, compared to some other toxic
pollutants.

The behavior of isophorone in a POTW has not been studied.  How-
ever, the biochemical oxidation of many of the toxic organic
pollutants has been investigated in laboratory scale studies at
concentrations higher than would normally be expected in munici-
pal wastewaters.  General observations relating molecular struc-
ture to ease of degradation have been developed  for all of these
pollutants.  The conclusion reached by the study of the limited
data is that biochemical treatment in a POTW produces moderate
removal of  isophorone.  This conclusion is consistent with the
findings of an experimental study of microbiological degradation
of isophorone which showed about 45 percent oxidation in 15 to 20
days in domestic wastewater, but only 9 percent  in salt water.
                               458

-------
No data were  found on the persistence of  isophorone  in  sewage
sludge.

Naphthalene (55).  Naphthalene is an aromatic hydrocarbon with
two orthocondensed benzene rings and a molecular  formula of
ClO^S-  As such  it is properly classed as a polynuclear
aromatic hydrocarbon (PAH).  Pure naphthalene is  a white crystal-
line solid melting at 80°C.  For a solid, it has  a relatively
high vapor pressure (0.05 mm Hg at 20 C), and moderate water
solubility (19 mg/1 at 20 C).  Napthalene is the  most abundant
single component of coal tar.  Production is more than  a third of
a million tons annually in the U.S.  About three  fourths of the
production is used as feedstock for phthalic anhydride manufac-
ture.  Most of the remaining production goes into manufacture of
insecticide,  dyestuffs, pigments, and pharmaceuticals.  Chlori-
nated and partially hydrogenated naphthalenes are used in some
solvent mixtures.  Naphthalene is also used as a  moth repellent.

Naphthalene,  ingested by humans, has reportedly caused vision
loss (cataracts), hemolytic anemia, and occasionally, renal dis-
ease.  These  effects of naphthalene ingestion are confirmed by
studies on laboratory animals.  No carcinogenicity studies are
available which  can be used to demonstrate carcinogenic activity
for naphthalene.  Naphthalene does bioconcentrate in aquatic
organisms.

For the protection of human health from the toxic properties of
naphthalene ingested through water and through contaminated
aquatic organisms, the ambient water criterion is determined to
be 143 mg/1.

Only a limited number of studies have been conducted to determine
the effects of naphthalene on aquatic organisms.  The data from
those studies show only moderate toxicity.

Naphthalene has been detected in sewage plant effluents at con-
centrations up to 0.022 mg/1 in studies carried out by the U.S.
EPA.   Influent levels were not reported.  The behavior of naph-
thalene in a POTW has not been studied.  However, recent studies
have determined that naphthalene will accumulate  in sediments at
100 times the concentration in overlying water.   These results
suggest that naphthalene will be readily removed  by primary and
secondary settling in a POTW, if it is not biologically degraded.

Biochemical oxidation of many of the toxic organic pollutants has
been investigated in laboratory scale studies at  concentrations
higher than would normally be expected in municipal wastewaters.
General observations relating molecular structure to ease of

degradation have been developed for all of these pollutants.  The
conclusion reached by study of the limited data is that biologi-
cal treatment produces a high removal by degradation of naphthal-
ene.  One recent study has shown that microorganisms can degrade
naphthalene, first to a dihydro compound, and ultimately to
carbon dioxide and water.

4-Nitrophenol (58).  4-Nitrophenol (N02C6H40H), also called
paranitrophenol, is a colorless to yellowish crystalline solid
manufactured commercially by hydrolysis of 4-chloro-nitrobenzene
with aqueous sodium hydroxide.  4-Nitrophenol melts at 114 C.
Vapor pressure is not cited in the usual sources.  4-Nitrophenol
is slightly soluble in water (15 g/1 at 25°C) and soluble in
organic solvents.  This phenol does not react to give a color
with 4-aminoantipyrene, and therefore does not contribute to the
nonconventional pollutant parameter "Total Phenols."  U.S. annual
production is about 20,000 tons.

Paranitrophenol is used to prepare phenetidine, acetaphenetidine,
azo and sulfur dyes, photochemicals, and pesticides.

The toxic effects of 4-nitrophenol on humans have not been exten-
sively studied.  Data from experiments with laboratory animals
indicate that exposure to this compound results in methmoglobi-
nemia (a metabolic disorder of blood), shortness of breath, and
stimulation followed by depression.  Other studies indicate that
the compound acts directly on cell membranes, and inhibits cer-
tain enzyme systems in vitro.  No information regarding potential
   teratogenicity was found.  Available data indicate that this
compound does not pose a mutagentc hazard to humans.  Very
limited data for 4-nitrophenol do not reveal potential
carcinogenic effects, although the compound has been selected by
the national cancer institute for testing under the Carcinogenic
Bioassay Program.

No U.S.  standards for exposure to 4-nitrophenol in ambient water
have been established.

Data on the behavior of 4-nitrophenol in a POTW are not avail-
able.   However, laboratory scale studies have been conducted at
concentrations higher than those expected to be found in munici-
pal wastewaters.  Biochemical oxidation using adapted cultures
from various sources produced 95 percent degradation in three to
six days in one study.  Similar results were reported for other
studies.  Based on these data, and on general observations
relating molecular structure to ease of biological oxidation, it
is concluded that complete or nearly complete removal of
4-nitrophenol occurs during biological treatment in a POTW.
                               460

-------
 2,4.-Dinitrophenol  (59).   2,4-Dinitrophenol  [(NO  )  C  H OH],  a
 yellow  crystalline  solid,  is  manufactured  commercially by
 hydrolysis  of  2,4-dinitro-l-chlorobenzene  with sodium hydroxide.
 2,4-Dinitrophenol sublimes at 114°C.  Vapor  pressure  is  not  cited
 in usual  sources.   It  is  slightly  soluble  in water  (7.0  g/1  at
 25°C) and soluble in organic  solvents.  This phenol does not
 react with  4-aminoantipyrene  and therefore does not contribute  to
 the nonconventional pollutant parameter "Total Phenols." U.S.
 annual  production is about 500 tons.

 2,4-Dinitrophenol is used  to  manufacture sulfur and azo  dyes,
 photochemicals, explosives, and pesticides.

 The toxic effects of 2,4-dinitrophenol in  humans  is generally
 attributed  to  their ability to uncouple oxidative phosphoryla-
 tion.   In brief, this  means that sufficient  2,4-dinitrophenol
 short-circuits cell metabolism by  preventing utilization of
 energy  provided by respiration and glycolysis.  Specific symp-
 toms are  gastrointestinal  disturbances, weakness, dizziness,
 headache, and  loss of weight.   More acute  poisoning includes
 symptoms  such  as:  burning thirst, agitation,  irregular  breath-
 ing, and  abnormally high fever.  This compound also inhibits
 other enzyme systems;  and  acts directly on the cell membrane,
 inhibiting  chloride permeability.  Ingestion of 2,4-dinitrophenol
 also causes cataracts  in humans.

 Based on  available data it appears unlikely  that  2,4-dinitro-
 phenol  poses a teratogenic hazard to humans.   Results  of studies
 of mutagenic activity  of this  compound are inconclusive  as far  as
 humans  are  concerned.  Available data suggest  that  2,4-dinitro-
 phenol  does not possess carcinogenic properties.

 To protect human health from  the adverse effects  of 2,4-dinitro-
 phenol  ingested in contaminated water and  fish, the suggested
 water quality criterion is 0.0686 mg/1 .

 Data on the behavior of 2,4-dinitrophenol  in a POTW are  not
 available.  However, laboratory scale studies  have  been  conducted
 at concentrations higher than  those expected to be  found in
 municipal wastewaters.   Biochemical oxidation  using a phenol-
 adapted seed culture produced  92 percent degradation  in  3.5
hours.   Similar results were reported for  other studies.  Based
 on these  data, and on general  observations relating molecular
 structure to ease of biological oxidation,  it  is  concluded that
 complete  or nearly complete removal of 2,4-dinitrophenol  occurs
 during biological treatment in  a POTW.

N-nitrsodiphenylamine (62).   N-nitrosodiphenylamine
              also called nitrous diphenylamide,  is a
                               461

-------
yellow crystalline solid manufactured by nitrosation of diphenyl-
amine.  It melts at 66 C and is insoluble in water, but soluble
in several organic solvents other than hydrocarbons.  Production
in the U.S. has approached 1,500 tons per year.  The compound is
used as a retarder for rubber vulcanization and as a pesticide
for control of scorch (a fungus disease of plants).

N-nitroso compounds are acutely toxic to every animal species
tested and are also poisonous to humans.  N-nitrosodiphenylamine
toxicity in adult rats lies in the mid range of the values for 60
N-nitroso compounds tested.  Liver damage is the principal toxic
effect.  N-nitrosodiphenylamine, unlike many other N-nitroso-
amines, does not show mutagenic activity.  N-nitrosodiphenylamine
has been reported by several investigations to be non-carcino-
genic.  However, the compound is capable of trans-nitrosation and
could thereby convert other amines to carcinogenic N-nitroso-
amines.  Sixty-seven of 87 N-nitrosoamines studied were reported
to have carcinogenic activity.  No water quality criterion have
been proposed for N-nitrosodiphenylamine.

No data are available on the behavior of N-nitrosodiphenylamine
in a POTW.  Biochemical oxidation of many of the toxic organic
pollutants have been investigated, at least in labgratory scale
studies, at concentrations higher than those expected to be con-
tained in most municipal wastewaters.   General observations have
been developed relating molecular structure to ease of degrada-
tion for all the toxic organic pollutants.  The conclusion
reached by study of the limited data is that biological treatment
produces little or no removal of N-nitrosodiphenylaraine in a
POTW,  No information is available regarding possible interfer-
ence by N-nitrosodiphenylamine in POTW processes, or on the
possible detrimental effect on sludge used to amend soils in
which crops are grown.  However, no interference or detrimental
effects are expected because N-nitroso compounds are widely dis-
tributed in the soil and water environment, at low concentra-
tions, as a result of microbial action on nitrates and
nitrosatable compounds.

Pentachlorophenol (64).   Pentachlorophenol (CfcC^OH) is a
white crystalline solid produced commercially by chlorination of
phenol or polychlorophenols.  U.S. annual production is in excess
of 20,000 tons.  Pentachlorophenol melts at 190°C and is slightly
soluble in water (14 mg/1).  Pentachlorophenol is not detected by
the 4-amino antipyrene method.

Pentachlorophenol is a bactericide and fungicide and is used for
preservation of wood and wood products.  It is competitive with
creosote in that application.  It is also used as a preservative
                               462

in glues,  starches, and photographic papers.
algicide and herbicide.
It is an effective
Although data are available on the human toxicity effects of pen-
tachlorophenol, interpretation of data is  frequently uncertain.
Occupational exposure observations must be examined carefully
because exposure to pentachlorophenol is frequently accompanied
by exposure to other wood preservatives.  Additionally, experi-
mental results and occupational exposure observations must be
examined carefully to make sure that observed effects are pro-
duced by the pentachlorophenol itself and not by the by-products
which usually contaminate pentachlorophenol.

Acute and chronic toxic effects of pentachlorophenol in humans
are similar; muscle weakness, headache, loss of appetite,
abdominal pain, weight loss, and irritation of skin, eyes, and
respiratory tract.  Available literature indicates that penta-
chlorophenol does not accumulate in body tissues to any signifi-
cant extent.  Studies on laboratory animals of distribution of
the compound in body tissues showed the highest levels of penta-
chlorophenol in liver, kidney, and intestine, while the lowest
levels were in brain, fat, muscle, and bone.

Toxic effects of pentachlorophenol in aquatic organisms are much
greater at pH 6 where this weak acid is predominantly in the
undissociated form than at pH 9 where the ionic form predomi-
nates.  Similar results were observed in mammals where oral
lethal doses of pentachlorophenol were lower when the compound
was administered in hydrocarbon solvents (un-ionized form) than
when it was administered as the sodium salt (ionized form) in
water.

There appear to be no significant teratogenic, mutagenic, or car-
cinogenic effects of pentachlorophenol.

For the protection of human health from the toxic properties of
pentachlorophenol ingested through water and through contaminated
aquatic organisms, the ambient water quality criterion is deter-
mined to be 0.140 mg/1.

Only limited data are available for reaching conclusions about
the behavior of pentachlorophenol in a POTW.  Pentachlorophenol
has been found in the influent to a POTW.  In a study of one POTW
the mean removal was 59 percent over a seven day period.  Trickl-
ing filters removed 44 percent at the influent pentachlorophenol,
suggesting that biological degradation occurs.  The same report
compared removal of pentachlorophenol at the same plant and two
additional POTW facilities on a later date and obtained values of
                               463

-------
4.4, 19.5 and 28.6 percent removal, the last value being for the
plant which was 59 percent removal in the original study.  Influ-
ent concentrations of pentachlorophenol ranged from 0.0014 to
0.0046 mg/1.  Other studies, including the general review of data
relating molecular structure to biological oxidation, indicate
that pentachlorophenol is not removed by biological treatment
processes in a POTW.  Anaerobic digestion processes are inhibited
by 0.4 mg/1 pentachlorophenol.

The low water solubility and low volatility of pentachlorophenol
lead to the expectation that most of the compound will remain in
the sludge in a POTW.  The effect on plants grown on land treated
with pentachlorophenol-containing sludge is unpredictable.
Laboratory studies show that this compound affects crop germina-
tion at 5.4 mg/1.  However, photodecomposition of pentachloro-
phenol occurs in sunlight.  The effects of the various breakdown
products which may remain in the soil was not found in the liter-
ture.

Phenol (65).  Phenol, also called hydroxybenzene and carbolic
acid, is a clear, colorless, hygroscopic, deliquescent, crystal-
line solid at room temperature.  Its melting point is 43°C and
its vapor pressure at room temperature is 0.35 mm Hg.  It is very
soluble in water (67 gm/1 at 16°C) and can be dissolved in ben-
zene, oils, and petroleum solids.  Its formula is C6H50H.

Although a small percent of the annual production of phenol is
derived from coal tar as a naturally occuring product, most of
the phenol is synthesized.  Two of the methods are fusion of ben-
zene sulfonate with sodium hydroxide, and oxidation of cumene
followed by cleavage with a catalyst.  Annual production in the
U.S. is in excess of one million tons.  Phenol is generated dur-
ing distillation of wood and the microbiological decomposition of
organic matter in the mammalian intestinal tract.

Phenol is used as a disinfectant, in the manufacture of resins,
dyestuffs, and in pharmaceuticals, and in the photo processing
industry.  In this discussion, phenol is the specific compound
which is separated by methylene chloride extraction of an
acidified sample and identified and quantified by GC/MS.  Phenol
also contributes to the "Total Phenols," discussed elsewhere
which are determined by the 4-AAP colorimetric method.

Phenol exhibits acute and sub-acute toxicity in humans and
laboratory animals.  Acute oral doses of phenol in humans cause
sudden collapse and unconsciousness by its action on the central
nervous system.  Death occurs by respiratory arrest.  Sub-acute
                               464

-------
oral  doses  in  mammals  are  rapidly  absorbed  and  quickly  distri-
buted to various organs, then cleared  from  the  body  by  urinary
excretion and  metabolism.  Long term exposure by  drinking phenol
contaminated water has resulted in statistically  significant
increase in reported cases of diarrhea, mouth sores,  and burning
of the mouth.  In laboratory animals,  long  term oral  administra-
tion  at low levels produced slight liver  and kidney  damage.  No
reports were found regarding carcinogenicity of phenol  adminis-
tered orally - all carcinogenicity studies  were skin  test.

For the protection of human health from phenol  ingested through
water and through contaminated aquatic organisms, the concen-
tration in  water should not exceed 3.4 mg/1.

Fish  and other aquatic organisms demonstrated a wide  range of
sensitivities to phenol concentration.  However,  acute  toxicity
values were at moderate levels when compared to other toxic
organic pollutants.

Data have been developed on the behavior  of phenol in a POTW.
Phenol is biodegradable by biota present  in a POTW.  The ability
of a POTW to treat phenol-bearing  influents depends upon acclima-
tion  of the biota and the constancy of the phenol concentration.
It appears that an induction period is required to build up the
population  of organisms which can  degrade phenol.  Too  large a
concentration will result in upset or pass though in  the POTW,
but the specific level causing upset depends on the  immediate
past history of phenol concentrations in  the influent.  Phenol
levels as high as 200 mg/1 have been treated with 95 percent
removal in  a POTW, but more or less continuous  presence of phenol
is necessary to maintain the population of microorganisms that
degrade phenol.

Phenol which is not degraded is expected  to pass through the POTW
because of  its very high water solubility.  However,  in a POTW
where chlorination is practiced for disinfection of the POTW
effluent,  chlorination of phenol may occur.  The products of that
reaction may be toxic pollutants.

The EPA has developed data on influent and effluent concentra-
tions of total phenols in a study  of 103 POTW facilities.  How-
ever,  the analytical procedure was the 4-AAP method mentioned
earlier and not the GC/MS method specifically for phenol.
Discussion of the study,  which of  course includes phenol, is
presented under the pollutant heading "Total Phenols."

Phthalate Esters (66-71).  Phthalic acid,  or 1,2-benzene-
dicarboxylic acid,  is one of three isomeric benzenedicarboxylic
acids produced by the chemical industry.  The other two isomeric
                               465

-------
forms are called isophthalic and terephthalic acids.  The  formula
for all three acids is C6H4(COOH)2-  Some esters of
phthalic acid are designated as toxic pollutants.  They will be
discussed as a group here, and specific properties of individual
phthalate esters will be discussed afterwards.

Phthalic acid esters are manufactured in the U.S. at an annual
rate in excess of one billion pounds.  They are used as plasti-
cizers - primarily in the production of polyvinyl chloride  (PVC)
resins.  The most widely used phthalate plasticizer is bis
(2-ethylhexyl) phthalate (66) which accounts for nearly one-third
of the phthalate esters produced.  This particular ester is com-
monly referred to as dioctyl phthalate (DOP) and should not be
confused with one of the less used esters, di-n-octyl phthalate
(69), which is also used as a plasticizer.  In addition to  these
two isomeric dioctyl phthalates, four other esters, also used
primarily as plasticizers, are designated as toxic pollutants.
They are:  butyl benzyl phthalate (67), di-n-butyl phthalate
(68), diethyl phthalate (70), and dimethyl phthalate (71).

Industrially, phthalate esters are prepared from phthalic  anhy-
dride and the specific alcohol to form the ester.  Some evidence
is available suggesting that phthalic acid esters also may  be
synthesized by certain plant and animal tissues.  The extent to
which this occurs in nature is not known.

Phthalate esters used as plasticizers can be present in concen-
trations up to 60 percent of the total weight of the PVC plastic.
The plasticizer is not linked by primary chemical bonds to  the
PVC resin.  Rather, it is locked into the structure of intermesh-
ing polymer molecules and held by van der Waals forces.  The
result is that the plasticizer is easily extracted.  Plasticizers
are responsible for the odor associated with new plastic toys or
flexible sheet that has been contained in a sealed package.

Although the phthalate esters are not soluble or are only  very
slightly soluble in water, they do migrate into aqueous solutions
placed in contact with the plastic.  Thus, industrial facilities
with tank linings, wire and cable coverings, tubing, and sheet
flooring of PVC are expected to discharge some phthalate esters
in their raw waste.  In addition to their use as plasticizers,
phthalate esters are used in lubricating oils and pesticide car-
riers.  These also can contribute to industrial discharge  of
phthalate esters.

From the accumulated data on acute toxicity in animals, phtha-
late esters may be considered as having a rather low order of
toxicity.  Human toxicity data are limited.  It is thought  that
                               466

-------
the toxic effects of the esters  is most  likely due  to  one  of  the
metabolic products, in particular the monoester.  Oral acute  tox-
icity in animals is greater  for  the  lower molecular weight esters
than for the higher molecular weight esters.

Orally administered phthalate esters generally produced enlarging
of liver and kidney, and atrophy of  testes  in laboratory animals.
Specific esters produced enlargement of heart and brain, spleen-
itis, and degeneration of central nervous system tissue.

Subacute doses administered  orally to laboratory animals produced
some decrease in growth and  degeneration of the testes.  Chronic
studies in animals showed similar effects to those  found in acute
and subacute studies, but to a much  lower degree.   The same
organs were enlarged, but pathological changes were not usually
detected.

A recent study of several phthalic esters produced  suggestive but
not conclusive evidence that dimethyl and diethyl phthalates have
a cancer liability.  Only four of the six toxic pollutant  esters
were included in the study.  Phthalate esters do bioconcentrate
in fish.  The factors, weighted  for  relative consumption of
various aquatic and marine food  groups, are used to calculate
ambient water quality criteria for four phthalate esters.   The
values are included in the discussion of the specific esters.

Studies of toxicity of phthalate esters in  freshwater and  salt
water organisms are scarce.  A chronic toxicity test with  bis (2-
ethylhexyl) phthalate showed that significant reproductive
impairment occurred at 0.003 mg/1 in the freshwater crustacean,
Daphnia magna.  In acute toxicity studies,  saltwater fish  and
organisms showed sensitivity differences of up to eight-fold to
butyl benzyl, diethyl, and dimethyl phthalates.  This suggests
that each ester must be evaluated individually for  toxic effects.

The behavior of phthalate esters in a POTW has not  been studied.
However, the biochemical oxidation of many  of the toxic organic
pollutants has been investigated in laboratory scale studies at
concentrations higher than would normally be expected in munici-
pal wastewaters.  Three of the phthalate esters were studed.
Bis(2-ethylhexyl) phthalate was  found to be degraded slightly or
not at all and its removal by biological treatment  in a POTW is
expected to be slight or zero.  Di-n-butyl phthalate and diethyl
phthalate were degraded to a moderate degree and their removal by
biological treatment in a POTW is expected  to occur to a moderate
degree.   Using these data and other observations relating molecu-
lar structure to ease of biochemical degradation of other  toxic
organic pollutants, the conclusion was reached that butyl benzyl
                               467

-------
phthalate and dimethyl phthalate would be removed  in a POTW to a
moderate degree by biological treatment.  On the same basis, it
was concluded that di-n-octyl phthalate would be removed to a
slight degree or not at all.  An EPA study of seven POTW facili-
ties revealed that for all but di-n-octyl phthalate, which was
not studied, removals ranged from 62 to 87 percent.

No information was found on possible interference with POTW oper-
ation or the possible effects on sludge by the phthalate esters.
The water insoluble phthalate esters - butyl benzyl and di-n-
octyl phthalate - would tend to remain in sludge, whereas the
other four toxic pollutant phthalate esters with water solubili-
ties ranging from 50 mg/1 to 4.5 mg/1 would probably pass through
into the POTW effluent.

Bis(2-ethylhexyl) phthalate (66).  In addition to the general
remarks and discussion on phthalate esters, specific information
on bis(2-ethylhexyl) phthalate is provided.  Little information
is available about the physical properties of bis(2-ethylhexyl)
phthalate.  It is a liquid boiling at 387°C at 5mm Hg and is
insoluble in water.  Its formula is C6H4(COOC8Hi7)2-
This toxic pollutant constitutes about one-third of the phthalate
ester production in the U.S.  It is commonly referred to as
dioctyl phthalate, or OOP, in the plastics industry where it is
the most extensively used compound for the plasticization of
polyvinyl chloride (PVC).  Bis(2-ethylhexyl) phthalate has been
approved by the FDA for use in plastics in contact with food.
Therefore, it may be found in wastewaters coming in contact with
discarded plastic food wrappers as well as the PVC films and
shapes normally found in industrial plants.  This toxic pollutant
is also a commonly used organic diffusion pump oil, where its low
vapor pressure is an advantage.

For the protection of human health from the toxic properties of
bis(2-ethylhexyl) phthalate ingested through water and through
contaminated aquatic organisms, the ambient water quality criter-
ion is determined to be 15 mg/1.  If contaminated aquatic organ-
isms alone are consumed, excluding the consumption of water, the
ambient water criteria is determined to be 50 mg/1.

Although the behavior of bis(2-ethylhexyl) phthalate in a POTW
has not been studied, biochemical oxidation of this toxic pollu-
tant has been studied on a laboratory scale at concentrations
higher than would normally be expected in municipal wastewater.
In fresh water with a non-acclimated seed culture no biochemical
oxidation was observed after 5, 10, and 20 days.  However, with
an acclimated seed culture, biological oxidation occured to the
extents of 13, 0, 6, and 23 percent of theoretical after 5, 10,
                               468

-------
15 and 20 days, respectively.  Bis(2-ethylhexyl) phthalate
concentrations were 3 to 10 mg/1.  Little or no removal  of
bis(2-ethylhexyl) phthalate by biological treatment  in a POTW  is
expected.

Butyl Benzyl Phthalate  (67).  In addition to the general remarks
and discussion on phthalate esters,  specific information on butyl
benzyl phthalate is provided.  No information was  found  on the
physical properties o£  this compound.

Butyl benzyl phthalate  is used as a  plasticizer for  PVC.  Two
special applications differentiate it from other phthalate
esters.  It is approved by the U.S.  FDA  for food contact in
wrappers and containers; and it is the industry standard for
plasticization of vinyl flooring because it provides stain
resistance.

No ambient water quality criterion is proposed for butyl benzyl
phthalate.

Butyl benzyl phthalate  removal in a  POTW by biological treatment
is expected to occur to a moderate degree.

Di-n-butyl Phthalate (68).  In addition to the general remarks
and discussion on phthalate esters,  specific information on di-
n-butyl phthalate (DBP) is provided.  DBP is a colorless, oil
liquid, boiling at 340 C.  Its water solubility at room  tempera-
ture is reported to be 0.4 g/1 and 4.5 g/1 in two different chem-
istry handbooks.  The formula for DBP, C6H4(COOC4H9>2
is the same as for its isomer, di-isobutyl phthalate.  DBP
production is 1 to 2 percent of total U.S. phthalate ester
production.

Dibutyl phthalate is used to a limited extent as a plasticizer
for polyvinyl chloride  (PVC).  It is not approved for contact
with food.  It is used in liquid lipsticks and as a  diluent for
polysulfide dental impression materials.  DBP is used as a plas-
ticizer for nitrocellulose in making gun powder, and  as  a fuel in
solid propellants for rockets.  Further uses are insecticides,
safety glass manufacture, textile lubricating agents, printing
inks,  adhesives, paper coatings,  and resin solvents.

For protection of human health from  the toxic properties of
dibutyl phthalate ingested through water and through contami-
nated aquatic organisms, the ambient water quality criterion is
determined to be 34 mg/1.  If contaminated aquatic organisms
alone are consumed, excluding the consumption of water,  the
ambient water criterion is 154 mg/1.
                               469

-------
Although the behavior of di-n-butyl phthalate in a POTW has not
been studied, biochemical oxidation of this toxic pollutant has
been studied on a laboratory scale at concentrations higher than
would normally be expected in municipal wastewaters.  Biochemical
oxidation of 35, 43, and 45 percent of theoretical oxidation were
obtained after 5, 10, and 20 days, respectively, using sewage
microorganisms as an unacclimated seed culture.

Biological treatment in a POTW is expected to remove di-n-butyl
phthalate to a moderate degree.

Di-n-octyl phthalate (69).  In addition to the general remarks
and discussion on phthalate esters, specific information on
di-n-octyl phthalate is provided.  Di-n-octyl phthalate is not to
be confused with the isomeric bis(2-ethylhexyl) phthalate which
is commonly referred to in the plastics industry as DOP.  Di-n-
octyl phthalate is a liquid which boils at 220°C at 5 mm Hg.  It
is insoluble in water.  Its molecular formula is CfiH4-
(COOC8Hi7)2-  Its production constitutes about 1 percent of
all phthalate ester production in the U.S.

Industrially, di-n-octyl phthalate is used to plasticize poly-
vinyl chloride (PVC) resins.

No ambient water quality criterion is proposed for di-n-octyl
phthalate.

Biological treatment in a POTW is expected to lead to little or
no removal of di-n-octyl phthalate.

Diethyl phthalate (70).  In addition to the general remarks and
discussion on phthalate esters, specific information on diethyl
phthalate is provided.  Diethyl phthalate, or DEP, is a colorless
liquid boiling at 296 C, and is insoluble in water.  Its molecu-
lar formula is C6H4(COOC2H5)2-  Production of diethyl
phthalate constitutes about 1.5 percent of phthalate ester
production in the U.S.

Diethyl phthalate is approved for use in plastic food containers
by the U.S. FDA.   In addition to its use as a polyvinyl chloride
(PVC) plasticizer, DEP is used to plasticize cellulose nitrate
for gun powder, to dilute polysulfide dental impression materi-
als, and as an accelerator for dyeing triacetate fibers.  An
additional use which would contribute to its wide distribution in
the environment is as an approved special denaturant for ethyl
alcohol.  The alcohol-containing products for which DEP is an
approved denaturant include a wide range of personal care items
such as bath preparations, bay rum, colognes, hair preparations,
                               470

-------
 face and hand creams, perfumes and toilet soaps.  Additionally,
 this denaturant is approved for use in biocides, cleaning  solu-
 tions, disinfectants, insecticides, fungicides, and room deoder-
 ants which have ethyl alcohol as part of the formulation.  It is
 expected, therefore, that people and buildings would have  some
 surface loading of this toxic pollutant which would find its way
 into raw wastewaters.

 For the protection of human health from the toxic properties of
 diethyl phthalate ingested through water and through contaminated
 aquatic organisms, the ambient water quality criterion is  deter-
 mined to be 350 mg/1.  If contaminated aquatic organisms alone
 are consumed, excluding the consumption of water, the ambient
 water criterion is 1,800 mg/1.

Although the behavior of diethyl phthalate in a POTW has not been
 studied, biochemical oxidation of this toxic pollutant has been
 studied on a laboratory scale at concentrations higher than would
 normally be expected in municipal wastewaters.  Biochemical oxi-
 dation of 79, 84, and 89 percent of theoretical was observed
 after 5, 15, and 20 days respectively.  Biological treatment in a
POTW is expected to lead to a moderate degree of removal of
 diethyl phthalate.

Dimethyl Phthalate (71).  In addition to the general remarks and
 discussion on phthalate esters, specific information on dimethyl
phthalate (DMP) is provided.  DMP has the lowest molecular weight
of the phthalate esters - M.W. * 194 compared to M.W. of 391 for
bis(2-ethylhexyl) phthalate.  DMP has a boiling point of 282°C.
It is a colorless liquid, soluble in water to the extent of 5
mg/1.  Its molecular formula is C6H4(C))CH3>2-

Dimethyl phthalate production in the U.S. is just under one per-
cent of total phthalate ester production.  DMP is used to some
extent as a plasticizer in cellulosics; however, its principal
specific use is for dispersion of polyvinylidene fluoride  (PVDF).
PVDF is resistant to most chemicals and finds use as electrical
 insulation, chemical process equipment (particularly pipe), and
 as a case for long-life finishes for exterior metal siding.  Coil
coating techniques are used to apply PVDF dispersions to aluminum
or galvanized steel siding.

For the protection of human health from the toxic properties of
dimethyl phthalate ingested through water and through contami-
nated aquatic organisms, the ambient water criterion is deter-
mined to be 313 mg/1.  If contaminated aquatic organisms alone
are consumed, excluding the consumption of water,  the ambient
water criterion is 2,900 mg/1.
                               471

-------
Based on limited data and observations relating molecular struc-
ture to ease of biochemical degradation of other toxic organic
pollutants, it is expected that dimethyl phthalate will be bio-
chemically oxidized to a lesser extent than domestic sewage by
biological treatment in a POTW.

Polynuclear Aromatic Hydrocarbons (72-84).  The polynuclear aro-
matic hydrocarbons (PAH) selected as toxic pollutants are a group
of 13 compounds consisting of substituted and unsubstituted poly-
cyclic aromatic rings.  The general class of PAH includes hetero-
cyclics, but none of those were selected as toxic pollutants.
PAH are formed as the result of incomplete combustion when
organic compounds are burned with insufficient oxygen.  PAH are
found in coke oven emissions, vehicular emissions, and volatile
products of oil and gas burning.  The compounds chosen as toxic
pollutants are listed with their structural formula and melting
point (m.p.).  All are insoluble in water.

Some of these toxic pollutants have commercial or industrial
uses.  Benzo(a)anthracene, benzo(a)pyrene, chrysene, anthracene,
dibenzo(a,h)anthracene, and pyrene are all used as antioxidants.
Chrysene, acenaphthylene, anthracene, fluorene, phenanthrene, and
pyrene are all used for synthesis of dyestuffs or other organic
chemicals.   3,4-Benzofluoranthrene, benzo(k)fluoranthene, benzo-
(ghi)perylene, and indeno (1,2,3-cd)pyrene have no known indus-
trial uses, according to the results of a recent literature
search.

Several of the PAH toxic pollutants are found in smoked meats, in
smoke flavoring mixtures, in vegetable oils, and in coffee.  Con-
                               473

-------
sequently, they are also found in many drinking water supplies.
The wide distribution of these pollutants in complex mixtures
with the many other PAHs which have not been designated as toxic
pollutants results in exposures by humans that cannot be associ-
ated with specific individual compounds.

The screening and verification analysis procedures used for the
toxic organic pollutants are based on gas chromatography (GC).
Three pairs of the PAH have identical elution times on the column
specified in the protocol, which means that the parameters of the
pair are not differentiated.  For these three pairs [anthracene
(78)  - phenanthrene (81); 3,4-benzofluoranthene (74) - benzo(k)-
flupranthene (75); and benzo(a)anthracene (72) - chrysene (76)]
results are obtained and reported as "either-or."  Either both
are present in the combined concentration reported, or one is
present in the concentration reported.

There are no studies to document the possible carcinogenic risks
to humans by direct ingestion.  Air pollution studies indicate an
excess of lung cancer mortality among workers exposed to large
amounts of PAH containing materials such as coal gas, tars, and
coke-oven emissions.  However, no definite proof exists that the
PAH present in these materials are responsible for the cancers
observed.

Animal studies have demonstrated the toxicity of PAH by oral and
dermal administration.  The carcinogenicity of PAH has been
traced to formation of PAH metabolites which, in turn, lead to
tumor formation.  Because the levels of PAH which induce cancer
are very low, little work has been done on other health hazards
resulting from exposure.  It has been established in animal
studies that tissue damage and systemic toxicity can result from
exposure to non-carcinogenic PAH compounds.

Because there were no studies available regarding chronic oral
exposures to PAH mixtures, proposed water quality criteria were
derived using data on exposure to a single compound.  Two studies
were selected, one involving benzo(a)pyrene ingestion and one
involving dibenzo(a,h)anthracene ingestion.  Both are known
animal carcinogens.

For the maximum protection of human health from the potential
carcinogenic effects of expsure to polynuclear aromatic hydrocar-
bons (PAH) through ingestion of water and contaminated aquatic
organisms, the ambient water concentration is zero.  Concentra-
tions of PAH estimated to result in additional risk of 1 in
100,000 were derived by the EPA and the Agency is considering
setting criteria at an interim target risk level in the range of
10~', 10~6, or 10~5 with corresponding criteria of
0.000000097 mg/1, 0.00000097 mg/1, and 0.0000097 mg/1,
respectively.
                               474

-------
No  standard  toxicity  tests have been  reported  for  freshwater  or
saltwater organisms and any of the 13 PAH  discussed here.

The behavior of PAH in a POTW has received only a  limited  amount
of  study.  It  is  reported that up to  90  percent of PAH  entering a
POTW will be retained in the sludge generated  by conventional
sewage  treatment  processes.  Some of  the PAH can inhibit bac-
terial  growth  when they are present at concentrations as low  as
0.018 mg/1.  Biological treatment in  activated sludge units has
been shown to  reduce the concentration of  phenanthrene  and
anthracene to  some extent; however, a study of biochemical oxi-
dation  of fluorene on a laboratory scale showed no degradation
after 5, 10, and  20 days.  On the basis  of that study and  studies
of other toxic organic pollutants, some  general observations  were
made relating  molecular structure to  ease  of degradation.  Those
observations lead to the conclusion that the 13 PAH selected  to
represent that group as toxic pollutants will  be removed only
slightly or  not at all by biological  treatment methods  in  a POTW.
Based on their water insolubility and tendency to  attach to sedi-
ment particles very little pass through  of PAH to  POTW  effluent
is expected.

No data are  available at this time to support  any  conclusions
about contamination of land by PAH on which sewage sludge  con-
taining PAH  is spread.

Tetrachlproethylene (85).  Tetrachloroethylene (CC12CC12),
also called  perchloroethylene and PCE, is  a colorless,  nonflam-
mable liquid produced mainly by two methods -  chlorination and
pyrolysis of ethane and propane, and oxychlorination of dichloro-
ethane.  U.S.  annual production exceeds  300,000 tons.   PCE boils
at 121°C and has a vapor pressure of 19  mm Hg  at 20°C.  It is
insoluble in water but soluble in organic  solvents.

Approximately  two-thirds of the U.S. production of PCE  is  used
for dry cleaning.  Textile processing and  metal degreasing, in
equal amounts  consume about one-quarter  of the U.S. production.

The principal  toxic effect of PCE on humans is central  nervous
system  depression when the compound is inhaled.  Headache,
fatigue, sleepiness, dizziness, and sensations of  intoxication
are reported.  Severity of effects increases with  vapor concen-
tration.  High integrated exposure (concentration  times duration)
produces kidney and liver damage.  Very  limited data on PCE
ingested by  laboratory animals indicate  liver  damage occurs when
PCE is  administered by that route.  PCE  tends  to distribute to
fat in  mammalian bodies.

One report found in the literature suggests, but does not  con-
clude,  that PCE is teratogenic.  PCE has been  demonstrated to be
a liver carcinogen in B6C3-F1 mice.

For  the maximum protection  of human health  from  the potential
carcinogenic effects of exposure to tetrachlorethylene through
ingestion  of water  and contaminated aquatic  organisms, the  ambi-
ent  water  concentration is  zero.  Concentrations  of tetrachloro-
ethylene estimated  to result in additional  lifetime cancer  risk
levels of  ID'/, iQ-6^ and iQ-5 are Q.000020  mg/1, 0.00020
mg/1, and  0.0020 mg/1, respectively.

No data were found  regarding the behavior of PGE  in a POTW.  Many
of the toxic organic pollutants have been investigated, at  least
in laboratory  scale studies, at concentrations higher than  those
expected to be contained by most municipal wastewaters.  General
observations have been developed relating molecular structure to
ease of degradation for all of the toxic organic  pollutants.  The
conclusions reached by the  study of the limited  data is that
bioloigical treatment produces a moderate removal  of PCE in  a POTW
by degradation.  No information was found to indicate that  PCE
accumulates in the  sludge,  but some PCE is expected to be
adsorbed onto  settling particles.  Some PCE  is expected to  be
volatilized in aerobic treatment processes and little, if any, is
expected to pass through into the effluent  from  the POTW.

Toluene (86).  Toluene is a clear, colorless liquid with a
benzene-like odor.  It is a naturally occuring compound derived
primarily  from petroleum or petrochemical processes.  Some
toluene is obtained from the manufacture of  metallurgical coke.
Toluene is also referred to as totuol, methylbenzene, methacide,
and phenylmethane.  It is an aromatic hydrocarbon with the
formula C6H5CH3.  it boils  at 111 C and has  a vapor pres-
sure of 30 mm Hg at room temperature.  The water  solubility of
toluene is 535 mg/1, and it is miscible with a variety of organic
solvents.   Annual production of toluene in the U.S. is greater
than two million metric tons.  Approximately two-thirds of  the
toluene is converted to benzene and the remaining 30 percent is
divided approximately equally into chemical  manufacture, and use
as a paint solvent and aviation gasoline additive.  An esti-
mated 5,000 metric tons is  discharged to the environment anually
as a constituent in wastewater.

Most data on the effects of toluene in human and other mammals
have been based on inhalation exposure or dermal  contact studies.
There appear to be no reports of oral administration of toluene
to human subjects.  A long  term toxicity study on female rats
revealed no adverse effects on growth, mortality, appearance and
behavior,  organ to body weight ratios, blood-urea nitrogen
levels, bone marrow counts, peripheral blood counts, or morphol-
ogy of major organs.  The effects of inhaled toluene on the cen-
tral nervous system, both at high and low concentrations, have
been studied in humans and  animals.  However, ingested toluene is
expected to be handled differently by the body because it is
absorbed more slowly and must first pass through  the liver  before
                              476

-------
 reaching  the  nervous  system.  Toluene  is  extensively  and  rapidly
 metabolized in the  liver.  One of the  principal  metabolic prod-
 ucts  of toluene  is  benzoic acid, which itself  seems to  have
 little potential to produce tissue injury.

 Toluene does  not appear to be teratogenic in laboratory animals
 or man.   Nor  is  there any conclusive evidence  that toluene is
 mutagenic.  Toluene has not been demonstrated  to be positive in
 any 15: vitro  mutagenicity or carcinogenicity bioassay system,  nor
 to be carcinogenic  in animals or man.

 Toluene has been found in fish caught  in harbor  waters  in the
 vicinity  of petroleum and petrochemical plants.  Bioconcentration
 studies have  not been conducted, but bioconcentration factors
 have been calculated on the basis of the  octanol-water  partition
 coefficient.

 For the protection  of human health from the toxic properties of
 toluene ingested through water and through contaminated aquatic
 organisms, the ambient water criterion is determined  to be 14.3
 mg/1.  If contaminated aquatic organisms  alone are consumed
 excluding the consumption of water, the ambient  water criterion
 is 424 mg/1.  Available data show that the adverse effects on
 aquatic life  occur  at concentrations as low as 5 mg/1.

Acute toxicity tests have been conducted with toluene and a
 variety of freshwater fish and Daphnia magna.  The latter appears
 to be significantly more resistant than fish.  No test  results
have been reported  for the chronic effects of toluene on
 freshwater fish or  invertebrate species.

No detailed study of toluene behavior  in a POTW  is available.
However,  the  biochemical oxidation of  many of the toxic pollu-
tants has been investigated in laboratory scale  studies at
 concentrations greater than those expected to be contained by
most municipal wastewaters.   At toluene concentrations  ranging
 from 3 to 250 mg/1  biochemical oxidation proceeded to 50  percent
of theoretical or greater.  The time period varied from a few
hours to  20 days depending on whether  or not the seed culture was
acclimated.   Phenol adapted acclimated seed cultures  gave the
most rapid and extensive biochemical oxidation.

Based on  study of the limited data, it is expected that toluene
will be biochemically oxidized to a lesser extent than  domestic
 sewage by biological treatment in a POTW.  The volatility  and
relatively low water solubility of toluene lead  to the  expecta-
tion that aeration  processes will remove significant  quantities
of toluene from the POTW.   The EPA studied toluene removal in
seven POTW facilities.  The removals ranged from 40 to  100
percent.   Sludge concentrations of toluene ranged from  54  x
10-3 to 1.85 mg/1.
                             477

Trichloroethylene  (87).  Trichloroethylene  (1,1,2-trichloroethyl-
ene or TCE) is a clear, colorless liquid boiling at 87°C.  It has
a vapor pressure of 77 mm Hg at room temperature and  is slightly
soluble in water (1 gm/1).  U.S. production is  greater than 0.25
million metric tons annually.  It is produced from tetrachloro-
ethane by treatment with lime in the presence of water.

TCE is used for vapor phase degreasing of metal parts, cleaning
and drying electronic  components, as a solvent  for paints, as a
refrigerant, for extraction of oils, fats, and  waxes, and for dry
cleaning.  Its widespread use and relatively high volatility
result in detectable levels in many parts of the environment.

Data on the effects produced by ingested TCE are limited.  Most
studies have been  directed at inhalation exposure.  Nervous sys-
tem disorders and  liver damage are frequent results of inhalation
exposure.  In the  short term exposures, TCE acts as a central
nervous system depressant - it was used as an anesthetic before
its other long term effects were defined.

TCE has been shown to  induce transformation in  a highly sensitive
in vitro Fischer rat embryo cell system (F1706) that  is used for
identifying carcinogens.  Severe and persistent toxicity to the
liver was recently demonstrated when TCE was shown to produce
carcinoma of the liver in mouse strain B6C3F1.  One systematic
study of TCE exposure and the incidence of human cancer was based
on 518 men exposed to TCE.  The authors of that study concluded
that although the  cancer risk to man cannot be  ruled  out, expo-
sure to low levels of TCE probably does not present a very
serious and general cancer hazard.

TCE is bioconcentrated in aquatic species, making the consumption
of such species by humans a significant source  of TCE.  For the
protection of human health from the potential carcinogenic
effects of exposure to trichloroethylene through ingestion of
water and contaminated aquatic organisms, the ambient water con-
centration is zero.  Concentrations of trichloroethylene esti-
mated to result in additional lifetime cancer risks of 10"'}
ID'6, and 10-5 are 2.7 x 10'4 mg/1, 2.7 x 10"3  tng/1,  and
2.7 x 10"2 mg/1, respectively.  If contaminated aquatic organ-
isms alone are consumed, excluding the consumption of water, the
water concentration should be less than 0.807 mg/1 to keep the
additional lifetime cancer risk below 10"-*.

Only a very limited amount of data on the effects of  TCE on
freshwater aquatic life are available.  One species of fish (fat-
head minnows) showed a loss of equilibrium at concentrations
below those resulting in lethal effects.

The behavior of trichloroethylene in a POTW has not been studied.
However, in laboratory scale studies of toxic organic pollutants,
                              478

-------
TCE was  subjected  to  biochemical  oxidation  conditions.  After  5,
10, and  20 days no biochemical oxidation occurred.  On  the basis
of this  study  and  general  observations  relating  molecular struc-
ture to  ease of degradation, the  conclusion is reached  that TGE
would undergo  no removal by biological  treatment  in a POTW.  The
volatility and relatively  low water  solubility of TCE is expected
to result in volatilization of some  of  the TCE in aeration steps
in a POTW.

Polychlorinated Biphenyls  (106 -  112).  Polychlorinated biphenyls
(Ci2HionCln,Hig-nCln  where n can  range  from 1 to  10),
designated PCB s, are chlorinated derivatives of  biphenyls.  The
commercial products are complex mixtures of chlorobiphenyls, but
are no longer produced in  the U.S.   The mixtures  produced for-
merly were characterized by the percentage  chlorination.  Direct
chlorination of biphenyl was used to produce mixtures containing
from 21  to 70 percent chlorine.   Seven  of these  mixtures have
been selected as toxic pollutants:

The arochlors 1221, 1232, 1016, 1242, and 1248 are colorless,
oily liquids; 1254 is a viscous liquid; 1260 is a sticky resin at
room temperature.  Total annual U.S. production of PCB's averaged
about 20,000 tons in 1972 to 1974.

Prior to 1971, PCB's were used in several applications including
plasticizers, heat transfer liquids, hydraulic fluids, lubri-
cants, vacuum pump and compressor fluids, and capacitor and
transformer oils.  After 1970, when PCB use was restricted to
closed systems, the latter two uses were the only commercial
applications.

The toxic effects of PCB's ingested by humans have been reported
to range from acne-like skin eruptions and pigmentation of the
skin to numbness of limbs, hearing and vision problems, and
spasms.  Interpretation of results is complicated by the fact
that the very highly toxic polychlorinated dibenzofurans (PCDF's)
are found in many commercial PCB mixtures.  Photochemical and
                              479

-------
thermal decomposition appear to accelerate the transformation of
PCB's to PCDF's.  Thus the specific effects of PCB's may be
masked by the effects of PCDF's.  However, if PCDF's are fre-
quently present to some extent in any PCB mixture, then their
effects may be properly included in the effects of PCB mixtures.

Studies of effects of PCB's in laboratory animals indicate that
liver and kidney damage, large weight losses, eye discharges, and
interference with some metabolic processes occur frequently.
Teratogenic effects of PCB's in laboratory animals have been
observed, but are rare.  Growth retardations during gestation,
and reproductive failure are more common effects observed in
studies of PCB teratogenicity.  Carcinogenic effects of PCB's
have been studied in laboratory animals with results interpreted
as positive.  Specific reference has been made to liver cancer in
rats in the discussion of water quality criterion formulation.

For the maximum protection of human health from the potential
carcinogenic effects of exposure to PCB's through ingestion of
water and contaminated aquatic organisms, the ambient water con-
centration should be zero.  Concentrations of PCB's estimated to
result in additional lifetime cancer risk at risk levels of
10-', 10-6, and iQ-5 are 0.0000000026 mg/1, 0.000000026
mg/1, and 0.00000026 mg/1, respectively.

The behavior of PCB's in a POTW has received limited study.  Most
PCB's will be removed with sludge.  One study showed removals of
82 to 89 percent, depending on suspended solid removal.  The
PCB's adsorb onto suspended sediments and other particulates.  In
laboratory scale experiments with PCB 1221, 81 percent was
removed by degradation in an activated sludge system in 47 hours.
Biodegradation can form polychlorinated dibenzofurans which are
more toxic than PCB's (as noted earlier).  PCB's at concentra-
tions of 0.1 to 1,000 mg/1 inhibit or enhance bacterial growth
rates, depending on the bacterial culture and the percentage
chlorine in the PCB.  Thus, activated sludge may be inhibited by
PCB's.  Based on studies of bioaccumulation of PCB's in food
crops grown on soils amended with PCB-containing sludge, the U.S.
FDA has recommended a limit of 10 mg PCB/kg dry weight of sludge
used for application to soils bearing food crops.

Antimony (114).   Antimony (chemical name - stibium, symbol Sb),
classified as a non-metal or metalloid, is a silvery white, brit-
tle crystalline solid.  Antimony is found in small ore bodies
throughout the world.  Principal ores are oxides of mixed anti-
mony valences, and an oxysulfide ore.  Complex ores with metals
are important because the antimony is recovered as a by-product.
Antimony melts at 631°C, and is a poor conductor of electricity
and heat.
                              480

-------
Annual U.S. consumption  of primary  antimony  ranges  from  10,000  to
20,000 tons.  About half is consumed  in metal products - mostly
antimonial  lead  for lead acid  storage batteries,  and  about half
in non-metal products.   A principal compound is antimony trioxide
which is used as  a flame retardant  in fabrics, and  as an opaci-
fier in glass, ceramics,  and enamels.  Several antimony  compounds
are used as catalysts  in organic  chemicals synthesis, as fluori-
nating agents (the antimony fluoride), as pigments, and  in fire-
works.  Semiconductor  applications  are economically significant.

Essentially no information on  antimony-induced human  health
effects has been  derived from  community epidemiology  studies.
The available data are in literature  relating effects observed
with therapeutic  or medicinal  uses  of antimony compounds and
industrial exposure studies.   Large therapeutic doses of anti-
monial compounds, usually used to treat schistisomiasis, have
caused severe nausea, vomiting, convulsions, irregular heart
action, liver damage, and skin rashes.  Studies of  acute
industrial antimony poisoning  have  revealed  loss  of appetite,
diarrhea, headache, and  dizziness in  addition to  the  symptoms
found in studies  of therapeutic doses of antimony.

For the protection of human health  from the  toxic properties of
antimony ingested through water and through  contaminated aquatic
organisms the ambient water criterion is determined to be 0.146
mg/1.  If contaminated aquatic organisms are consumed, excluding
the consumption of water, the  ambient water  criterion is deter-
mined to be 45 mg/1.   Available data  show that adverse effects  on
aquatic life occur at concentrations  higher  than  those cited for
human health risks.

Very little information  is available  regarding the  behavior of
antimony in a POTW.  The limited solubility  of most antimony
compounds expected in a  POTW,  i.e., the oxides and  sulfides, sug-
gests that at least part  of the antimony entering a POTW will be
precipitated and incorporated  into the sludge.  However, some
antimony is expected to  remain dissolved and pass through the
POTW into the effluent.   Antimony compounds remaining in the
sludge under anaerobic conditions may be connected  to stibine
(SbH3),  a very soluble and very toxic compound.   There are no
data to show antimony inhibits any POTW processes.  Antimony is
not known to be essential to the growth of plants,  and has been
reported to be moderately toxic.  Therefore, sludge containing
large amounts of antimony could be detrimental to plants if it  is
applied in large amounts  to cropland.

Arsenic (115).  Arsenic  (chemical symbol As), is  classified as  a
non-metal or metalloid.   Elemental arsenic normally exists in the
alpha-crystalline metallic form which is steel gray and  brittle,
and in the beta form which is  dark gray and  amorphous.  Arsenic
sublimes at 615°C.  Arsenic is widely distributed throughout the
                              481

-------
world in a large number of minerals.  The most important commer-
cial source of arsenic is as a by-product from treatment of
copper, lead, cobalt, and gold ores.  Arsenic is usually marketed
as the trioxide  (As203).  Annual U.S. production of the tri-
oxide approaches 40,000 tons.

The principal use of arsenic is in agricultural chemicals  (herbi-
cides) for controlling weeds in cotton fields.  Arsenicals have
various applications in medicinal and vetrinary use, as wood
preservatives, and in semiconductors.

The effects of arsenic in humans were known by the ancient Greeks
and Romans.  The principal toxic effects are gastrointestinal
disturbances.  Breakdown of red blood cells occurs.  Symptoms of
acute poisoning  include vomiting, diarrhea, abdominal pain,
lassitude, dizziness, and headache.  Longer exposure produced
dry, falling hair, brittle, loose nails, eczema, and exfoliation.
Arsenicals also exhibit teratogenic and mutagenic effects in
humans.  Oral administration of arsenic compounds has been
associated clinically with skin cancer for nearly one hundred
years.  Since 1888 numerous studies have linked occupational
exposure and therapeutic administration of arsenic compounds to
increased incidence of respiratory and skin cancer.

For the maximum protection of human health from the potential
carcinogenic effects of exposure to arsenic through ingestion of
water and contaminated aquatic organisms, the ambient water con-
centration is zero.  Concentrations of arsenic estimated to
result in additional lifetime cancer risk levels of 10"',
10"6, and 10-5 are 2.2 x 10-' mg/1, 2.2 x 10'6 mg/1, and
2.2 x 10"5 rag/l, respectively.  If contaminated aquatic organ-
isms alone are consumed, excluding the consumption of water, the
water concentration should be less than 1.75 x 10"^ to keep the
increased lifetime cancer risk below 10"^.  Available data show
that adverse effects on aquatic life occur at concentrations
higher than those cited for human health risks.

A few studies have been made regarding the behavior of arsenic in
a POTW.  One EPA survey of nine POTW facilities reported influent
concentrations ranging from 0.0005 to 0.693 mg/1; effluents from
three a POTW having biological treatment contained 0.0004 to 0.01
mg/1; two POTW facilities showed arsenic removal efficiencies of
50 and 71 percent in biological treatment.  Inhibition of treat-
ment processes by sodium arsenate is reported to occur at 0.1
mg/1 in activated sludge, and 1.6 mg/1 in anaerobic digestion
processes.  In another study based on data from 60 POTW facili-
ties, arsenic in sludge ranged from 1.6 to 65.6 mg/kg and the
median value was 7.8 mg/kg. Arsenic in sludge spread on cropland
may be taken up by plants grown on that land.  Edible plants can
take up arsenic, but normally their growth is inhibited before
the plants are ready for harvest.

Beryllium  (117).  Beryllium is a dark gray metal  of  the  alkaline
earth family.   It is relatively rare, but because of its unique
properties finds widespread use as an alloying element,  espe-
cially for hardening copper which is used in springs, electrical
contacts, and non-sparking tools.  World production  is reported
to be in the range of 250 tons annually.  However, much  more
reaches the environment as emissions from coal burning opera-
tions.  Analysis of coal indicates an average beryllium  content
of 3 ppm and 0.1 to 1.0 percent in coal ash or fly ash.

The principal ores are beryl  (3BeO.Al203«6Si02) and
bertrandite [Be4Si207(OH>2J.  Only two industrial
facilities produce beryllium  in the U.S. because  of  limited
demand and the  highly toxic character.  About two-thirds of the
annual production goes into alloys, 20 percent into  heat sinks,
and 10 percent  into beryllium oxide (BeO) ceramic products.

Beryllium has a specific gravity of 1.846, making it  the lightest
metal with a high melting point (1,350°C).  Beryllium alloys are
corrosion resistant, but the metal corrodes in aqueous environ-
ments.  Most common beryllium compounds are soluble  in water, at
least to the extent necessary to produce a toxic  concentration of
be ry11ium ions.

Most data on toxicity of beryllium is for inhalation  of beryllium
oxide dust.  Some studies on orally administered beryllium in
laboratory animals have been reported.  Despite the  large number
of studies implicating beryllium as a carcinogen, there is no
recorded instance of cancer being produced by ingestion.  How-
ever, a recently convened panel of uninvolved experts concluded
that epidemiologic evidence is suggestive that beryllium is a
carcinogen in man.

In the aquatic environment beryllium is chronically toxic to
aquatic organisms at 0.0053 mg/1.  Water softness has a  large
effect on beryllium toxicity to fish.   In soft water, beryllium
is reportedly 100 times as toxic as in hard water.

For the maximum protection of human health from the potential
carcinogenic effects of exposure to beryllium through ingestion
of water and contaminated aquatic organisms the ambient water
concentration is zero.   Concentrations of beryllium estimated to
result in additional lifetime cancer risk levels of 10"',
lO-o, and iQ-5 are 0.00000068 mg/1, 0.0000068 mg/1, and
0.000068 mg/1, respectively.   If contaminated aquatic organisms
alone are consumed excluding the consumption of water, the con-
centration should be less than 0.00117 mg/1 to keep  the increased
lifetime cancer risk below 10"->.

Information on the behavior of beryllium in a POTW is scarce.
Because beryllium hydroxide is insoluble in water, most beryllium

entering a POTW will probably be in the form of  suspended solids.
As a result most of the beryllium will settle and be removed with
sludge.  However, beryllium has been shown to inhibit several
enzyme systems, to interfere with DNA metabolism in liver, and to
induce chromosomal and mitotic abnormalities.  This intereference
in cellular processes may extend to interfere with biological
treatment processes.  The concentration and effects of beryllium
in sludge which could be applied to cropland has not been
studied.

Cadmium (118).  Cadmium is a relatively rare metallic element
that is seldom found in sufficient quantities in a pure state to
warrant mining or extraction from the earth's surface.  It is
found in trace amounts of about 1 ppm throughout the earth's
crust.  Cadmium is, however, a valuable by-product of zinc pro-
duction.

Cadmium is used primarily as an electroplated metal, and is found
as an impurity in the secondary refining of zinc, lead, and
copper.

Cadmium is an extremely dangerous cumulative toxicant, causing
progressive chronic poisoning in mammals, fish,  and probably
other organisms.  The metal is not excreted.

Toxic effects of cadmium on man have been reported from through-
out the world.  Cadmium may be a factor in the development of
such human pathological conditions as kidney disease, testicular
tumors, hypertension, arteriosclerosis, growth inhibition,
chronic disease of old age, and cancer.  Cadmium is normally
ingested by humans through food and water as well as by breathing
air contaminated by cadmium dust.  Cadmium is cumulative in the
liver, kidney, pancreas, and thyroid of humans and other animals.
A severe bone and kidney syndrome known as itai-itai disease has
been documented in Japan as caused by cadmium ingestion via
drinking water and contaminated irrigation water.  Ingestion of
as little as 0.6 mg/day has produced the disease.  Cadmium acts
synergistically with other metals.  Copper and zinc substantially
increase its toxicity.

Cadmium is concentrated by marine organisms, particularly
molluscs,  which accumulate cadmium in calcareous tissues and in
the viscera.  A concentration factor of 1,000 for cadmium in fish
muscle has been reported, as have concentration  factors of 3,000
in marine plants and up to 29,600 in certain marine animals.  The
eggs and larvae of fish are apparently more sensitive than adult
fish to poisoning by cadmium, and crustaceans appear to be more
sensitive than fish eggs and larvae.

For the protection of human health from the toxic properties of
cadmium ingested through water and through contaminated aquatic
                              484

-------
 organisms,  the  ambient  water  criterion is  determined to be 0.010
 mg/1.  Available  data show  that  adverse effects  on aquatic life
 occur  at  concentrations in  the same  range  as  those cited for
 human  health, and they  are  highly  dependent on water hardness.

 Cadmium is  not  destroyed when it is  introduced into a POTW,  and
 will either pass  through to the  POTW effluent or be incorporated
 into the  POTW sludge.   In addition,  it can interfere with the
 POTW treatment  process.

 In a study  of 189 POTW  facilities, 75  percent of the primary
 plants, 57  percent of the trickling  filter plants,  66 percent of
 the activated sludge plants,  and 62  percent of the biological
 plants allowed  over 90  percent of  the  influent cadmium to pass
 through to  the  POTW effluent.  Only  two of the 189 POTW facili-
 ties allowed less than  20 percent  pass-through,  and none less
 than 10 percent pass-through.  POTW  effluent  concentrations
 ranged from 0.001  to 1.97 mg/1 (mean 0.028 mg/1,  standard
 deviation 0.167 mg/1).

 Cadmium not passed through  the POTW  will be retained in the
 sludge where it is likely to  build up  in concentration.   Cadmium
 contamination of  sewage  sludge limits  its  use on land since  it
 increases the level of  cadmium in  the  soil.   Data show that
 cadmium can be  incorporated into crops,  including vegetables and
 grains, from contaminated soils.   Since the crops themselves show
 no adverse  effects from soils  with levels  up  to  100 mg/kg cad-
 mium, these contaminated crops could have  a significant  impact  on
 human health.   Two Federal  agencies  have already recognized  the
 potential adverse human  health effects  posed  by  the use  of sludge
 on cropland.  The FDA recommends that  sludge  containing  over 30
 mg/kg of  cadmium  should  not be used  on  agricultural land.  Sewage
 sludge contains 3  to 300 mg/kg (dry  basis) of cadmium mean = 10
 mg/kg; median » 16 mg/kg.  The USDA  also recommends placing
 limits on the total cadmium from sludge that  may be applied  to
 land.

 Chromium  (119).   Chromium is an  elemental  metal  usually  found as
 a chromite  (FeO.Cr203).  The  metal is  normally produced  by
 reducing the oxide with  aluminum.  A significant proportion  of
 the chromium used  is in  the form of  compounds  such  as sodium
 dichromate  (Na2Cr04>, and chromic acid  (Cr03)  -  both are
 hexavalent chromium compounds.

 Chromium  is found as an  alloying component of  many  steels  and its
 compounds are used in electroplating baths, and  as  corrosion
 inhibitors for  closed water circulation systems.

The two chromium  forms most frequently  found  in  industry waste-
waters are hexavalent and trivalent  chromium.  Hexavalent  chro-
 mium is the form used for metal  treatments.   Some  of it  is
                               485

-------
reduced to trivalent chromium as part of the process reaction.
The raw wastewater containing both valence states is usually
treated first to reduce remaining hexavalent to trivalent chro-
mium, and second to precipitate the trivalent form as the hydrox-
ide.  The hexavalent form is not removed by lime treatment.

Chromium, in its various valence states, is hazardous to man.  It
can produce lung tumors when inhaled, and induces skin sensitiza-
tions.  Large doses of chromates have corrosive effects on the
intestinal tract and can cause inflammation of the kidneys.
Hexavalent chromium is a known human carcinogen.  Levels of chro-
mate ions that show no effect in man appear to be so low as to
prohibit determination, to date.

The toxicity of chromium salts to fish and other aquatic life
varies widely with the species, temperature, pH, valence of the
chromium, and synergistic or antagonistic effects, especially the
effect of water hardness.  Studies have shown that trivalent
chromium is more toxic to fish of some types than is hexavalent
chromium.  Hexavalent chromium retards growth of one fish species
at 0.0002 mg/1.  Fish food organisms and other lower forms of
aquatic life are extremely sensitive to chromium.  Therefore,
both hexavalent and trivalent chromium must be considered harmful
to particular fish or organisms.

For the protection of human health from the toxic properties of
chromium (except hexavalent chromium) ingested through water and
contaminated aquatic organisms, the ambient water quality crite-
rion is 170 mg/1.  If contaminated aquatic organisms alone are
consumed, excluding the consumption of water, the ambient water
criterion for trivalent chromium is 3,443 mg/1.  The ambient
water quality criterion for hexavalent chromium is recommended to
be identical to the existing drinking water standard for total
chromium which is 0.050 mg/1.

Chromium is not destroyed when treated by a POTW (although the
oxidation state may change), and will either pass through to the
POTW effluent or be incorporated into the POTW sludge.  Both oxi-
dation states can cause POTW treatment inhibition and can also
limit the usefulness of municipal sludge.

Influent concentrations of chromium to POTW facilities have been
observed by EPA to range from 0.005 to 14.0 mg/1, with a median
concentration of 0.1 mg/1.  The efficiencies for removal of chro-
mium by the activated sludge process can vary greatly, depending
on chromium concentration in the influent, and other operating
conditions at the POTW.  Chelation of chromium by organic matter
and dissolution due to the presence of carbonates can cause
deviations from the predicted behavior in treatment systems.
                               486

-------
The  systematic presence  of  chromium  compounds will halt nitrifi-
cation in a POTW  for short  periods,  and most of  the  chromium will
be retained in the  sludge solids.  Hexavalent chromium has been
reported to severely affect the nitrification process, but tri-
valent chromium has little  or no toxicity  to activated sludge,
except at high concentrations.  The  presence of  iron, copper, and
low  pH will increase the toxicity of chromium in a POTW by
releasing the chromium into solution to be ingested  by micro-
organisms in the  POTW.

The  amount of chromium which passes  through to the POTW effluent
depends on the type of treatment processes used  by the POTW.  In
a study of 240 POTW facilities, 56 percent of the primary plants
allowed more than 80 percent pass-through  to POTW effluent.  More
advanced treatment results  in less pass-through.  POTW effluent
concentrations ranged from 0.003 to  3.2 mg/1 total chromium (mean
« 0.197, standard deviation = 0.48),  and from 0.002  to 0.1 mg/1
hexavalent chromium (mean - 0.017, standard deviation - 0.020).

Chromium not passed through the POTW will be retained in the
sludge, where it  is likely to build  up in  concentration.  Sludge
concentrations of total  chromium of  over 20,000  mg/kg (dry basis)
have been observed.  Disposal of sludges containing  very high
concentrations of trivalent chromium can potentially cause prob-
lems in uncontrolled landfills.  Incineration, or similar
destructive oxidation processes, can produce hexavalent chromium
from lower valence states.  Hexavalent chromium  is potentially
more toxic than trivalent chromium.   In cases where  high rates of
chrome sludge application on land are used, distinct growth
inhibition and plant tissue uptake have been noted.

Pretreatment of discharges substantially reduces  the concentra-
tion of chromium  in sludge.   In Buffalo, New York, pretreatment
of electroplating waste  resulted in  a decrease in chromium con-
centrations in POTW sludge  from 2,510 to 1,040 mg/kg.  A similar
reduction occurred in Grand Rapids,  Michigan, POTW facilities
where the chromium concentration in  sludge decreased from 11,000
to 2,700 mg/kg when pretreatment was  made a requirement.

Copper (120).   Copper is a metallic  element that  sometimes is
found free, as the native metal, and is also found in minerals
such as cuprite (Cu20),  malachite [CuC03.Cu(OH)2], azurite
[2CuC03.Cu(OH)2], chalcopyrite (CuFeS2), and bornite
(Cu5Fe§4).   Copper is obtained from  these ores by smelting,
leaching, and electrolysis.   It is used in the plating, electri-
cal,  plumbing,  and heating equipment  industries,  as well as in
insecticides and  fungicides.

Traces of copper  are found in all forms of plant  and animal life,
and the metal  is  an essential trace  element for  nutrition.
Copper is not  considered to be a cumulative systemic poison for
                              487

-------
humans as tt is readily excreted by the body, but it can cause
symptoms of gastroenteritis, with nausea and intestinal irrita-
tions, as relatively low dosages.  The limiting factor in domes-
tic water supplies is taste.  To prevent this adverse organolep-
tic effect of copper in water, a criterion of 1 mg/1 has been
established.

The toxicity of copper to aquatic organisms varies significantly,
not only with the species, but also with the physical and chemi-
cal characteristics of the water, including temperature, hard-
ness, turbidity, and carbon dioxide content.  In hard water, the
toxicity of copper salts may be reduced by the precipitation of
copper carbonate or other insoluble compounds.  The sulfates of
copper and zinc, and of copper and calcium are synergistic in
their toxic effect on fish.

Relatively high concentrations of copper may be tolerated by
adult fish for short periods of time; the critical effect of
copper appears to be its higher toxicity to young or juvenile
fish.  Concentrations of 0.02 to 0.03 mg/1 have proved fatal to
some common fish species.  In general the salmonoids are very
sensitive and the sunfishes are less sensitive to copper.

The recommended criterion to protect freshwater aquatic life is
0.0056 mg/1 as a 24-hour average, and 0.012 mg/1 maximum concen-
tration at a hardness of 50 mg/1 CaC03.  For total recoverable
copper the criterion to protect freshwater aquatic life is 0.0056
mg/1 as a 24-hour average.

Copper salts cause undesirable color reactions in the food indus-
try and cause pitting when deposited on some other metals such as
aluminum and galvanized steel.  To control undesirable taste and
odor quality of ambient water due to the organoleptic properties
of copper, the estimated level is 1.0 mg/1 for total recoverable
copper.

Irrigation water containing more than minute quantities of copper
can be detrimental to certain crops.  Copper appears in all
soils, and its concentration ranges from 10 to 80 ppm.  In soils,
copper occurs in association with hydrous oxides of manganese and
iron, and also as soluble and insoluble complexes with organic
matter.  Copper is essential to the life of plants, and the
normal range of concentration in plant tissue is from 5 to 20
ppm.  Copper concentrations in plants normally do not build up to
high levels when toxicity occurs.  For example, the concentra-
tions of copper in snapbean leaves and pods was less than 50 and
20 mg/kg, respectively, under conditions of severe copper toxic-
ity.  Even under conditions of copper toxicity, most of the
excess copper accumulates in the roots; very little is moved to
the aerial part of the plant.
                               488

-------
 Copper  is  not  destroyed when  treated  by  a POTW,  and will  either
 pass through to the POTW effluent or  be  retained in the POTW
 sludge.  It can interfere with  the POTW  treatment processes  and
 can limit  the  usefulness of municipal sludge.

 The influent concentration of copper  to  a POTW has been observed
 by the  EPA to  range from 0.01 to 1.97 mg/1, with a median concen-
 tration of 0.12 mg/1.  The copper that is removed from the
 influent stream of a POTW is  absorbed on the  sludge or appears  in
 the sludge as  the hydroxide of  the metal.  Bench scale pilot
 studies  have shown that from  about 25 percent to 75 percent  of
 the copper passing through the  activated sludge  process remains
 in solution in the final effluent.  Four-hour slug dosages of
 copper  sulfate in concentrations exceeding 50 mg/1 were reported
 to have  severe effects on the removal efficiency of an unaccli-
 mated system, with the system returning  to normal in about 100
 hours.   Slug dosages of copper  in the form of copper cyanide were
 observed to have much more severe effects on the activated sludge
 system,  but the total system  returned to normal  in 24 hours.

 In a recent study of 268 POTW facilities, the median pass-through
 was over 80 percent for primary plants and 40 to 50 percent  for
 trickling  filter, activated sludge, and  biological treatment
 plants.  POTW effluent concentrations  of copper  ranged from  0.003
 to 1.8 mg/1 (mean 0.126, standard deviation 0.242).

 Copper which does not pass through the POTW will be retained in
 the sludge where it will build up in  concentration.  The  presence
 of excessive levels of copper in sludge  may limit its use on
 cropland.  Sewage sludge contains up  to  16,000 mg/kg of copper,
 with 730 mg/kg as the mean value.  These concentrations are
 significantly greater than those normally found  in soil,  which
 usually  range  from 18 to 80 mg/kg.  Experimental data indicate
 that when  dried sludge is spread over  tillable land, the  copper
 tends to remain in place down to the  depth of the tillage, except
 for copper which is taken up by plants grown in  the soil.  Recent
 investigation has shown that the extractable copper content  of
 sludge-treated soil decreased with time,  which suggests a  rever-
 sion of  copper to less soluble  forms  was occurring.

 Cyanide  (121).   Cyanides are among the most toxic of pollutants
 commonly observed in industrial wastewaters.  Introduction of
 cyanide  into industrial processes is  usually by  dissolution  of
 potassium  cyanide (KCN) or sodium cyanide (NaCN)  in process
waters.  However,  hydrogen cyanide (HCN)  formed  when the  above
 salts are  dissolved in water,  is probably the most acutely lethal
 compound.

The relationship of pH to hydrogen cyanide formation is very
 important.   As  pH is lowered to below 7,  more than 99 percent of
 the cyanide is  present as HCN and less than 1 percent as  cyanide
                               489

-------
ions.  Thus, at neutral pH, that of most living organisms, the
more toxic form of cyanide prevails.

Cyanide ions combine with numerous heavy metal ions to form com-
plexes.  The complexes are in equilibrium with HCN.  Thus, the
stability of the metal-cyanide complex and the pH determine the
concentration of HCN.  Stability o£ the metal-cyanide anion com-
plexes is extremely variable.  Those formed with zinc, copper,
and cadmium are not stable - they rapidly dissociate, with pro-
duction of HCN, in near neutral or acid waters.  Some of the com-
plexes are extremely stable.  Cobaltocyanide is very resistant to
acid distillation in the laboratory.  Iron cyanide complexes are
also stable, but undergo photodecomposition to give HCN upon
exposure to sunlight.  Synergistic effects have been demonstrated
for the metal cyanide complexes making zinc, copper, and cadmium
cyanides more toxic than an equal concentration of sodium
cyanide.

The toxic mechanism of cyanide is essentially an inhibition of
oxygen metabolism, i.e., rendering the tissues incapable of
exchanging oxygen.  The cyanogen compounds are true noncumulative
protoplasmic poisons.  They arrest the activity of all forms of
animal life.  Cyanide shows a very specific type of toxic action.
It inhibits the cytochrome oxidase system.  This system is the
one which facilitates electron transfer from reduced metabolites
to molecular oxygen.  The human body can convert cyanide to a
non-toxic thiocyanate and eliminate it.  However, if the quantity
of cyanide ingested is too great at one time, the inhibition of
oxygen utilization proves fatal before the detoxifying reaction
reduces the cyanide concentration to a safe level.

Cyanides are more toxic to fish than to lower forms of aquatic
organisms such as midge larvae, crustaceans, and mussels.  Toxic-
ity to fish is a function of chemical form and concentration, and
is influenced by the rate of metabolism (temperature), the level
of dissolved oxygen, and pH.  In laboratory studies free cyanide
concentrations ranging from 0.05 to 0.14 mg/1 have been proven to
be fatal to sensitive fish species including trout, bluegill, and
fathead minnows.  Levels above 0.2 mg/1 are rapidly fatal to most
fish species.  Long term sublethal concentrations of cyanide as
low as 0.01 mg/1 have been shown to affect the ability of fish to
function normally, e.g., reproduce, grow, and swim.

For the protection of human health from the toxic properties of
cyanide ingested through water and through contaminated aquatic
organisms, the ambient water quality criterion is determined to
be 0.200 mg/1.

Persistence of cyanide in water is highly variable and depends
upon the chemical form of cyanide in the water, the concentration
of cyanide, and the nature of other constituents.  Cyanide may be
                               490

-------
destroyed by  strong oxidizing agents  such  as permanganate  and
chlorine.  Chlorine is commonly used  to oxidize  strong  cyanide
solutions.  Carbon dioxide  and nitrogen are the  products of  com-
plete oxidation.  But if the reaction is not complete,  the very
toxic compound, cyanogen chloride, may remain  in the  treatment
system and subsequently be  released to the environment.  Partial
chlorination  may occur as part of a POTW treatment, or  during the
disinfection  treatment of surface water for drinking  water prep-
aration.

Cyanides can  interfere with treatment processes  in a  POTW, or
pass through  to ambient waters.  At low concentrations  and with
acclimated microflora, cyanide may be decomposed by microorga-
nisms in anaerobic and aerobic environments or waste  treatment
systems.  However, data indicate that much of  the cyanide  intro-
duced passes  through to the POTW effluent.  The  mean  pass-through
of 14 biological plants was 71 percent.  In a  recent  study of 41
POTW facilities the effluent concentrations ranged from 0.002 to
100 mg/1 (mean - 2.518, standard deviation - 15.6).   Cyanide also
enhances the  toxicity of metals commonly found in POTW  effluents,
including the toxic pollutants cadmium, zinc,  and copper.

Data for Grand Rapids, Michigan, showed a significant decline in
cyanide concentrations downstream from the POTW  after pretreat-
ment regulations were put in force.   Concentrations fell from
0.66 mg/1 before, to 0.01 mg/1 after  pretreatment was required.

Lead (122).  Lead is a soft, malleable, ductile,  blueish-gray,
metallic element, usually obtained from the mineral galena (lead
sulfide, PbS), anglesite (lead sulfate, PbS04>,  or cerussite
(lead carbonate, PbC03).  Because it  is usually  associated with
minerals of zinc, silver, copper, gold, cadmium,  antimony, and
arsenic, special purification methods are frequently  used  before
and after extraction of the metal from the ore concentrate by
sme It ing.

Lead is widely used for its corrosion resistance, sound and
vibration absorption, low melting point (solders), and  relatively
high imperviousness to various forms  of radiation.  Small  amounts
of copper,  antimony and other metals  can be alloyed with lead to
achieve greater hardness, stiffness,  or corrosion resistance than
is afforded by the pure metal.   Lead  compounds are used in glazes
and paints.  About one third of U.S.  lead consumption goes into
storage batteries.   About half of U.S. lead consumption is from
secondary lead recovery.   U.S.  consumption of lead is in the
range of one million tons annually.

Lead ingested by humans produces a variety of toxic effects
including impaired reproductive ability,  disturbances in blood
chemistry,  neurological disorders,  kidney damage, and adverse
cardiovascular effects.  Exposure to  lead in the  diet results in
                               491

-------
permanent increase  in lead levels  in the body.  Most  of  the  lead
entering the body eventually becomes localized in  the bones  where
it accumulates.  Lead is a carcinogen or cocarcinogen in some
species of experimental animals.  Lead is teratogenic in experi-
mental animals.  Mutagenicity data are not available  for lead.

The ambient water quality criterion for lead  is recommended  to be
identical to the existng drinking water standard which is 0.050
mg/1.  Available data show that adverse effects on aquatic life
occur at concentrations as low as 7.5 x 10"4  mg/1  of  total
recoverable lead as a 24-hour average with a  water hardness  of 50
mg/1 as CaC03.

Lead is not destroyed in a POTW, but is passed through to the
effluent or retained in the POTW sludge; it can interfere with
POTW treatment processes and can limit the usefulness of POTW
sludge for application to agricultural croplands.   Threshold con-
centration for inhibition of the activated sludge  process is 0.1
mg/1, and for the nitrification process is 0.5 mg/1.  In a study
of 214 POTW facilities, median pass through values  were  over 80
percent for primary plants and over 60 percent for trickling
filter, activated sludge, and biological process plants.  Lead
concentration in POTW effluents ranged from 0.003  to  1.8 mg/1
(mean = 0.106 mg/1, standard deviation - 0.222).

Application of lead-containing sludge to cropland  should not lead
to uptake by crops under most conditions because normally lead is
strongly bound by soil.  However, under the unusual condition of
low pH (less than 5.5) and low concentrations of labile  phos-
phorus, lead solubility is increased and plants can accumulate
lead.

Mercury (123).  Mercury is an elemental metal rarely  found in
nature as the free metal.  Mercury is unique  among  metals as it
remains a liquid down to about 39 degrees below zero.  It is
relatively inert chemically and is insoluble  in water.   The
principal ore is cinnabar (HgS).

Mercury is used industrially as the metal and as mercurous and
mercuric salts and compounds.  Mercury is used in  several types
of batteries.  Mercury released to the aqueous environment is
subject to biomethylation - conversion to the extremely  toxic
methyl mercury.

Mercury can be introduced into the body through the skin and the
respiratory system as the elemental vapor.  Mercuric salts are
highly toxic to humans and can be absorbed through  the gastro-
intestinal tract.   Fatal doses can vary from 1 to 30 grams.
Chronic toxicity of methyl mercury is evidenced primarily by
neurological symptoms.  Some mercuric salts cause  death  by kidney
failure.
                              492

-------
Mercuric salts are extremely toxic to  fish  and  other  aquatic
life.  Mercuric chloride is more lethal than copper,  hexavalent
chromium, zinc, nickel, and lead towards  fish and  aquatic  life.
In the food cycle, algae containing mercury up  to  100 times the
concentration in the surrounding sea water  are  eaten  by  fish
which further concentrate the mercury.  Predators  that eat the
fish in turn concentrate the mercury even further.

For the protection of human health from the toxic  properties of
mercury ingested through water and through contaminated  aquatic
organisms the ambient water criterion  is  determined to be  0.0002
mg/1.

Mercury is not destroyed when treated  by  a POTW, and  will  either
pass through to the POTW effluent or be incorporated  into  the
POTW sludge.  At low concentrations it may reduce  POTW removal
efficiencies, and at high concentrations  it may upset the  POTW
operation.

The influent concentrations of mercury to a POTW have been
observed by the EPA to range from 0.002 to 0.24 mg/1, with a
median concentration of 0.001 mg/1.  Mercury has been reported in
the literature to have inhibiting effects upon  an  activated
sludge POTW at levels as low as 0.1 mg/1.  At 5 mg/1  of  mercury,
losses of COD removal efficiency of 14 to 40 percent  have  been
reported, while at 10 mg/1 loss of removal of 59 percent has been
reported.  Upset of an activated sludge POTW is reported in the
literature to occur near 200 mg/1.  The anaerobic  digestion pro-
cess is much less affected by the presence of mercury, with
inhibitory effects being reported at 1,365 mg/1.

In a study of 22 POTW facilities having secondary  treatment, the
range of removal of mercury from the influent to the  POTW  ranged
from 4 to 99 percent with median removal  of 41 percent.  Thus
significant pass through of mercury may occur.

In sludges, mercury content may be high if industrial sources of
mercury contamination are present.  Little is known about  the
form in which mercury occurs in sludge.   Mercury may  undergo
biological methylation in sediments, but  no methylation has been
observed in soils, mud, or sewage sludge.

The mercury content of soils not receiving additions  of POTW
sewage sludge lie in the range from 0.01  to 0.5 mg/kg.  In soils
receiving POTW sludges for protracted periods,  the concentration
of mercury has been observed to approach  1.0 mg/kg.   In the soil,
mercury enters into reactions with the exchange complex of clay
and organic fractions, forming both ionic and covalent bonds.
Chemical and microbiological degradation  of mercurials can take
place side by side in the soil, and the products - ionic or
molecular - are retained by organic matter and  clay or may be
                              493

-------
volatilized  if  gaseous.  Because  of  the high  affinity  between
mercury and  the solid soil surfaces, mercury  persists  in  the

Mercury can  enter plants through  the roots, it  can  readily move
to other parts  of the plant, and  it  has been  reported  to  cause
injury to plants.   In many plants mercury  concentrations  range
from 0.01 to 0.20 mg/kg, but when plants are  supplied  with high
levels of mercury,  these concentrations can exceed  0.5 mg/kg.
Bioconcentration occurs in animals ingesting  mercury in food.

Nickel (124).   Nickel is seldom found in nature as  the pure ele-
mental metal.   It is a relatively plentiful element and is widely
distributed  throughout the earth s crust.  It occurs in marine
organisms and is found in the oceans.  The chief  commercial ores
for nickel are  pentlandite [ (Fe,Ni)9Sg] > and  a  lateritic  ore
consisting of hydrated nickel-iron-magnesium  silicate.

Nickel has many and varied uses.  It is used  in alloys and as the
pure metal.  Nickel salts are used for electroplating  baths.

The toxicity of nickel to man is thought to be very low,  and sys-
temic poisoning of human beings by nickel  or  nickel salts is
almost unknown.  In non-human mammals nickel  acts to inhibit
insulin release, depress growth, and reduce cholesterol.  A high
incidence of cancer of the lung and  nose has  been reported in
humans engaged  in the refining of nickel.

Nickel salts can kill fish at very low concentrations.  However,
nickel has been found to be less toxic to  some fish than  copper,
zinc, and iron.  Nickel is present in coastal and open ocean
water at concentrations in the range of 0.0001 to 0.006 mg/1
although the most common values are  0.002  to  0.003  mg/1.  Marine
animals contain up to 0.4 mg/1 and marine  plants contain  up to 3
mg/1.  Higher nickel concentrations  have been reported to cause
reduction in photosynthetic activity of the giant kelp.   A low
concentration was found to kill oyster eggs.

For the protection of human health based on the toxic  properties
of nickel ingested through water and through  contaminated aquatic
organisms, the  ambient water criterion is  determined to be 0.0134
mg/1.  If contaminated aquatic organisms are  consumed, excluding
consumption  of  water, the ambient water criterion is determined
to be 0.100 mg/1.  Available data show that adverse effects on
aquatic life occur for total recoverable nickel concentrations as
low as 0.0071 mg/1 as a 24-hour average.

Nickel is not destroyed when treated in a  POTW, but will  either
pass through to the POTW effluent or be retained in the POTW
sludge.  It can interfere with POTW  treatment processes and can
also limit the  usefulness of municipal sludge.
                               494

-------
Nickel  salts have  caused  inhibition of  the biochemical  oxidation
of sewage in a POTW.  In  a pilot plant,  slug doses of nickel
significantly reduced normal  treatment  efficiencies  for a  few
hours,  but the plant acclimated itself  somewhat to the  slug dos-
age and appeared to achieve normal treatment efficiencies  within
40 hours.  It has  been reported that the anaerobic digestion pro-
cess  is inhibited  only by high concentrations  of nickel, while  a
low concentration  of nickel inhibits the nitrification  process.

The influent concentration of nickel to  a POTW has been observed
by the  EPA to range from 0.01 to 3.19 mg/1, with a median  of 0.33
mg/1.   In a study  of 190 POTW facilities, nickel pass-through was
greater than 90 percent for 82 percent  of the  primary plants.
Median  pass-through for trickling filter, activated  sludge, and
biological process plants was greater than 80 percent.   POTW
effluent concentrations ranged from 0.002 to 40 mg/1 (mean *
0.410,  standard deviation • 3.279).

Nickel  not passed  through the POTW will be incorporated into the
sludge.  In a recent two-year study of eight cities, four  of the
cities  had median  nickel  concentrations  of over 350 mg/kg, and
two were over 1 ,000 mg/kg.  The maximum nickel concentration
observed was 4,010 mg/kg.

Nickel  is found in nearly all soils, plants, and waters.   Nickel
has no known essential function in plants.  In soils, nickel
typically is found in the range from 10  to 100 mg/kg.   Various
environerantal exposures to nickel appear to correlate with
increased incidence of tumors in man.  For example, cancer in the
maxillary antrum of snuff users may result from using plant
materials grown on soil high  in nickel.

Nickel  toxicity may develop in plants from application  of  sewage
sludge  on acid soils.  Nickel has caused reduction of yields for
a variety of crops including oats, mustard, turnips, and cabbage.
In one  study nickel decreased the yields of oats significantly  at
100 mg/kg.

Whether nickel exerts a toxic effect on plants depends  on  several
soil factors, the  amount of nickel applied, and the contents of
other metals in the sludge.  Unlike copper and zinc, which are
more available from inorganic sources than from sludge,  nickel
uptake  by plants seems to be promoted by the presence of the
organic matter in  sludge.  Soil treatments, such as liming,
reduce  the solubility of nickel.   Toxicity of nickel to  plants  is
enhanced in acidic soils.

Selenium (125).   Selenium (chemical symbol Se) is a non-metallic
element existing in several allotropic forms.  Gray selenium,
which has a metallic appearance,  is the stable form at  ordinary
temperatures and melts at 220°C.   Selenium is a major component
                               495

-------
of 38 minerals and a minor component of 37 others found in
various parts of the world.  Most selenium is obtained as a
by-product of precious metals recovery from electrolytic copper
refinery slimes.  U.S. annual production at one time reached one
million pounds.

Principal uses of selenium are in semi-conductors, pigments,
decoloring of glass, zerography, and metallurgy.  It also is used
to produce ruby glass used in signal lights.  Several selenium
compounds are important oxidizing agents in the synthesis of
organic chemicals and drug products.

While results of some studies suggest that selenium may be an
essential element in human nutrition, the toxic effects of
selenium in humans are well established.  Lassitude, loss of
hair, discoloration and loss of fingernails are symptoms of
selenium poisoning.  In a fatal case of ingestion of a larger
dose of selenium acid, peripheral vascular collapse, pulmonary
edema, and coma occurred.  Selenium produces mutagenic and tera-
togenic effects, but it has not been established as exhibiting
carcinogenic activity.

For the protection of human health from the toxic properties of
selenium ingested through water and through contaminated aquatic
organisms, the ambient water criterion is determined to be 0.010
mg/1, i.e., the same as the drinking water standard.  Available
data show that adverse effects on aquatic life occur at concen-
trations higher than that cited for human toxicity.

Very few data are available regarding the behavior of selenium in
a POTW.  One EPA survey of 103 POTW facilities revealed one POTW
using biological treatment and having selenium in the influent.
Influent concentration was 0.0025 mg/1, effluent concentration
was 0.0016 mg/1, giving a removal of 37 percent.  It is not known
to be inhibitory to POTW processes.  In another study, sludge
from POTW facilities in 16 cities was found to contain from 1.8
to 8.7 mg/kg selenium, compared to 0.01 to 2 mg/kg in untreated
soil.  These concentrations of selenium in sludge present a
potential hazard for humans or other mammals eating crops grown
on soil treated with selenium-containing sludge.

Silver (126).  Silver is a soft, lustrous, white metal that is
insoluble in water and alkali.  In nature, silver is found in the
elemental state (native silver) and combined in ores such as
argentite (Ag2S), horn silver (AgCl), proustite (Ag3AsS3),
and pyrargyrite (Ag3SbS3).  Silver is used extensively in
several industries, among them electroplating.

Metallic silver is not considered to be toxic, but most of its
salts are toxic to a large number of organisms.  Upon ingestion
                               496

-------
 by  humans,  many silver salts  are  absorbed in the circulatory sys-
 tem and  deposited  in  various  body tissues,  resulting in general-
 ized or  sometimes  localized gray  pigmentation of the skin and
 mucous membranes known as  argyria.  There is no  known method for
 removing silver from  the tissues  once  it  is deposited,  and the
 effect is cumulative.

 Silver is recognized  as  a  bactericide  and doses  from 0.000001  to
 0.0005 mg/1 have been reported  as sufficient to  sterilize water.
 The criterion  for  ambient  water to  protect  human health from the
 toxic properties of silver ingested through water and through
 contaminated aquatic  organisms  is 0,010 mg/1.

 The chronic toxic  effects  of  silver on the  aquatic environment
 have  not been  given as much attention  as  many other heavy metals.
 Data  from existing literature support  the fact that silver is
 very  toxic  to  aquatic organisms.   Despite the fact that silver is
 nearly the  most toxic of the heavy  metals,  there are insufficient
 data  to  adequately evaluate even  the effects of  hardness on
 silver toxicity.   There  are no  data available  on the toxicity  of
 different forms of silver.

 There is no available literature  on the incidental removal of
 silver by a POTV.  An incidental  removal  of about 50 percent is
 assumed  as  being representative.  This is the  highest average
 incidental  removal of any  metal for which data are available.
 (Copper has been indicated to have  a median incidental  removal
 rate  of 49  percent.)

 Bioaccumulation and concentration of silver from sewage sludge
 has not been studied  to  any great degree.   There is  some  indica-
 tion  that silver could be bioaccumulated  in mushrooms to  the
 extent that there  could  be adverse  physiological effects  on
humans if they consumed  large quantities  of mushrooms grown in
 silver enriched soil.  The effect,  however,  would tend  to be
unpleasant rather than fatal.

There is little summary  data available on the  quantity  of silver
 discharged  to  a POTW.  Presumably there would  be a tendency to
 limit its discharge from a manufacturing  facility because of its
high  intrinsic value.

Thallium (127).  Thallium  (Tl) is a soft, silver-white,  dense,
 malleable metal.  Five major minerals contain  15  to  85  percent
 thallium, but  they are not of commercial  importance  because the
metal is produced in  sufficient quantity  as  a  by-product  of lead-
 zinc  smelting  of sulfide ores.  Thallium  melts at 304°C.   U.S.
annual production of thallium and its compounds  is estimated to
be 1,500 pounds.

Industrial uses of thallium include the manufacture  of  alloys,
electronic devices and special glass.   Thallium  catalysts  are
used  for industrial organic syntheses.
                               497

-------
Acute thallium poisoning in humans has been widely described.
Gastrointestinal pains and diarrhea are followed by abnormal
sensation in the legs and arms, dizziness, and, later, loss of
hair.  The central nervous system is also affected.  Somnolence,
delerlum or coma may occur.  Studies on the teratogenicity of
thallium appear inconclusive; no studies on mutagenicity were
found; and no published reports on carcinogenicity of  thallium
were found.

For the protection of human health from the toxic properties of
thallium ingested through water and contaminated aquatic
organisms, the ambient water criterion is 0.004 mg/1.

No reports were found regarding the behavior of thallium in a
POTW.  It will not be degraded, therefore It must pass through to
the effluent or be removed with the sludge.  However,  since the
sulfide (TlS) is very insoluble, if appreciable sulfide is
present dissolved thallium in the influent to a POTW may be pre-
cipitated into the sludge.  Subsequent use of sludge bearing
thallium compounds as a soil amendment to crop bearing soils may
result in uptake of this element by food plants.  Several leafy
garden crops (cabbage, lettuce, leek, and endive) exhibit rela-
tively higher concentrations of thallium than other foods such as
meat.

Zinc (128).  Zinc occurs abundantly in the earth's crust, con-
centrated in ores.  It is readily refined into the pure, stable,
silver-white metal.  In addition to Its use in alloys, zinc is
used as a protective coating on steel.  It is applied by hot dip-
ing (i.e., dipping the steel in molten zinc) or by electroplat-
ing.

Zinc can have an adverse effect on man and animals at high con-
centrations.  Zinc at concentrations in excess of 5 mg/1 causes
an undesirable taste which persists through conventional treat-
ment.  For the prevention of adverse effects due to these organo-
leptic properties of zinc, 5 mg/1 was adopted for the  ambient
water criterion.   Available data show that adverse effects on
aquatic life occur at concentrations as low as 0.047 mg/1 as a
24-hour average.

Toxic concentrations of zinc compounds cause adverse changes in
the morphology and physiology of fish.  Lethal concentrations in
the range of O.I mg/1 have been reported.  Acutely toxic concen-
trations induce cellular breakdown of the gills, and possibly the
clogging of the gills with mucous.  Chronically toxic concentra-
tions of zinc compounds cause general enfeeblement and widespread
histological changes to many organs, but not to gills.  Abnormal
swimming behavior has been reported at 0.04 mg/1.  Growth and
maturation are retarded by zinc.  It has been observed that the
effects of zinc poisoning may not become apparent immediately, so
that fish removed from zinc-contaminated water may die as long as
48 hours after removal.
                               498

-------
In general,  salmonoids are most  sensitive  to  elemental zinc  in
soft water;  the rainbow trout is the most  sensitive in hard
waters.  A complex relationship  exists between zinc concentra-
tion, dissolved zinc concentration, pH, temperature, and calcium
and magnesium concentration.  Prediction of harmful effects  has
been less than reliable and controlled studies have not been
extensively  documented.

The major concern with zinc compounds in marine waters is not
with acute lethal effects, but rather with the long-term sub-
lethal effects of the metallic compounds and  complexes.  Zinc
accumulates  in some marine species, and marine animals contain
zinc in the  range of 6 to 1,500 mg/kg.  From  the point of view of
acute lethal effects, invertebrate marine  animals seem to be the
most sensitive organism tested.

Toxicities of zinc in nutrient solutions have been demonstrated
for a number of plants.  A variety of fresh water plants tested
manifested harmful symptoms at concentrations of 0.030 to 21.6
mg/1.  Zinc sulfate has also been found to be lethal to many
plants and it could impair agricultural uses  of the water.

Zinc is not destroyed when treated by a POTW, but will either
pass through to the POTW effluent or be retained in the POTW
sludge.  It  can interfere with treatment processes in the POTW
and can also limit the usefulness of municipal sludge.

In slug doses, and particularly in the presence of copper, dis-
solved zinc can interfere with or seriously disrupt the operation
of POTW biological processes by reducing overall removal effi-
ciencies, largely as a result of the toxicity of the metal to
biological organisms.  However, zinc solids in the form of
hydroxides or sulfides do not appear to interfere with biological
treatment processes, on the basis of available data.  Such solids
accumulate in the sludge.

The influent concentrations of zinc to a POTW has been observed
by the EPA to range from 0.017 to 3.91 mg/1, with a median con-
centration of 0.33 mg/1.   Primary treatment is not efficient in
removing zinc; however, the microbial floe of secondary treatment
readily adsorbs zinc.

In a study of 258 POTW facilities, the median pass-through values
were 70 to 88 percent for primary plants, 50 to 60 percent for
trickling filter and biological process plants, and 30 to 40 per-
cent for activated process plants.  POTW effluent concentrations
of zinc ranged from 0.003 to 3.6 mg/1 (mean = 0.330, standard
deviation - 0.464).

The zinc which does not pass through the POTW is retained in the
sludge.  The presence of zinc in sludge may limit its use on
                               499

-------
cropland.  Sewage sludge contains 72 to over 30,000 mg/kg of
zinc, with 3,366 mg/kg as the mean value.  These concentrations
are significantly greater than those normally found in soil,
which range from 0 to 195 mg/kg, with 94 mg/kg being a common
level.  Therefore, application of sewage sludge to soil will
generally increase the concentration of zinc in the soil.  Zinc
can be toxic to plants, depending upon soil pH.  Lettuce, toma-
toes, turnips, mustard, kale, and beets are especially sensitive
to zinc contamination.

Aluminum.  Aluminum, a nonconventional pollutant, is an abundant
silvery white metal comprising 8.1 percent of the earth's crust,
but never found in a free state.  The principal ore for aluminum
is bauxite from which alumina (A1203) is extracted.  Aluminum
metal is produced by electrolysis of the alumina in the cryolite
bath.

Aluminum metal is relatively corrosion resistant because it forms
a protective oxide film on the surface which prevents corrosion
under many conditions.  Electrolytic action of other metals in
contact with aluminum and strong acids and alkalis can break down
the oxide layer causing rapid corrosion to occur.

Aluminum is light, malleable, ductile, possesses high thermal and
electrical conductivity, and is non-magnetic.  It can be formed,
machined or cast.  Aluminum is used in the construction, trans-
portation, and container industries and competes with iron and
steel in these markets.

There are no reported adverse physiological effects on man from
low concentrations of aluminum in drinking water, however, large
concentrations of aluminum in the human body are alledged to
cause changes in behavior.  Salts of aluminum are used as coagu-
lants in water treatment, and in limited quantities do not have
any adverse effects on POTW operations.  Some aluminum salts are
soluble, however, mildly alkaline conditions cause precipitation
of aluminum as hydroxide.  The precipitation of aluminum hydrox-
ide can have an adverse effect on rooted aquatics and inverte-
brate benthos.
Oil and Grease.
tant parameter.
components are:
Oil and grease are taken together as one pollu-
This is a conventional pollutant and some of its
     1.  Light Hydrocarbons - These include light fuels such as
gasoline, kerosene, and jet fuel, and miscellaneous solvents used
for industrial processing, degreasing, or cleaning purposes.  The
presence of these light hydrocarbons may make the removal of
other heavier oil wastes more difficult.

     2.  Heavy Hydrocarbons, Fuels, and Tars - These include the
crude oils, diesel oils, //6 fuel oil, residual oils, slop oils,
and in some cases, asphalt and road tar.
                               500

-------
     3.  Lubricants and Cutting Fluids  - These  generally  fall
into two classes:  non-emulsifiable oils such as  lubricating oils
and greases and  emulsifiable oils  such  as water soluble oils,
rolling oils, cutting oils, and drawing compounds.  Emulsifiable
oils may contain fat, soap, or various  other additives.

     4.  Vegetable and Animal Fats and Oils - These originate
primarily from processing of foods and natural  products.

These compounds  can settle or float and may exist as  solids or
liquids depending upon factors such as method of use, production
process, and temperature of water.

Oil and grease even in small quantities cause troublesome taste
and odor problems.  Scum lines from these agents are  produced on
water treatment  basin walls and other containers.  Fish and water
fowl are adversely affected by oils in their habitat.  Oil emul-
sions may adhere to the gills of fish causing suffocation, and
the flesh of fish is tainted when microorganisms that were
exposed to waste oil are eaten.  Deposition of  oil in the bottom
sediments of water can serve to inhibit normal  benthic growth.
Oil and grease exhibit an oxygen demand.

Many of the toxic organic pollutants will be found distributed
between the oil  phase and the aqueous phase in  industrial waste-
waters.  The presence of phenols, PCS's, PAH's, and almost any
other organic pollutant in the oil and grease make characteriza-
tion of this parameter almost impossible.  However, all of these
other organics add to the objectionable nature  of the oil and
grease.

Levels of oil and grease which are toxic to aquatic organisms
vary greatly, depending on the type and the species susceptibil-
ity.  However,  it has been reported that crude  oil in concentra-
tions as low as 0.3 mg/1 is extremely toxic to  freshwater fish.
It has been recommended that public water supply sources be
essentially free from oil and grease.

Oil and grease in quantities of 100 1/sq km show up as a sheen on
the surface of a body of water.  The presence of oil slicks
decreases the aesthetic value of a waterway.

Oil and grease is compatible with a POTW activated sludge process
in limited quantity.   However,  slug loadings or high concentra-
tions of oil and grease interfere with biological treatment
processes.   The oils coat surfaces and solid particles, prevent-
ing access of oxygen, and sealing in some microorganisms.   Land
spreading of POTW sludge containing oil and grease uncontaminated
by toxic pollutants is not expected to affect crops grown on the
treated land, or animals eating those crops.
                               501

-------
pH.  Although not a  specific pollutant, pH  is  related  to  the
acidity or alkalinity of a wastewater stream.  It is not, how-
ever, a measure of either.  The term pH is  used  to describe the
hydrogen ion concentration (or activity) present in a  given solu-
tion.  Values for pH range from 0 to 14, and these numbers are
the negative logarithms of the hydrogen ion concentrations.  A pH
of 7 indicates neutrality.  Solutions with  a pH  above  7 are alka-
line, while those solutions with a pH below 7  are acidic.  The
relationship of pH and acidity and alkalinity  is not necessarily
linear or direct.  Knowledge of the water pH is useful in deter-
mining necessary measures for corrosion control, sanitation, and
disinfection.  Its value is also necessary  in  the treatment of
industrial wastewaters to determine amounts of chemicals  required
to remove pollutants and to measure their effectiveness.  Removal
of pollutants, especially dissolved solids  is  affected by the pH
of the wastewater.

Waters with a pH below 6.0 are corrosive to water works struc-
tures, distribution  lines, and household plumbing fixtures and
can thus add constituents to drinking water such as iron, copper,
zinc, cadmium, and lead.  The hydrogen ion  concentration  can
affect the taste of the water, and at a low pH water tastes sour.
The bactericidal effect of chlorine is weakened  as the pH
increases, and it is advantageous to keep the  pH close to 7.0.
This is significant  for providing safe drinking water.

Extremes of pH or rapid pH changes can exert stress conditions or
kill aquatic life outright.  Even moderate  changes from accept-
able criteria limits of pH are deleterious  to  some species.

The relative toxicity to aquatic life of many  materials is
increased by changes in the water pH.  For  example, metallocya-
nide complexes can increase a thousand-fold in toxicity with a
drop of 1.5 pH units.

Because of the universal nature of pH and its  effect on water
 Duality and treatment, it is selected as a  pollutant parameter
 or many industry categories.  A neutral pH range (approximately
6 to 9) is generally desired because either extreme beyond this
range has a deleterious effect on receiving waters or  the pollu-
tant nature of other wastewater constituents.

Pretreatment for regulation of pH is covered by  the "General Pre-
treatment Regulations for Existing and New  Sources of  Pollution,"
40 CFR 403.5.  This  section prohibits the discharge to a  POTW of
"pollutants which will cause corrosive structural damage  to the
POTW but in no case discharges with pH lower than 5.0  unless the
works is specially designed to accommodate  such discharges."

Total Suspended Solids (TSS).  Suspended solids  include both
organic and inorganic materials.  The inorganic  compounds include
sand, silt, and clay.  The organic fraction Includes such materi-
als as grease, oil,  tar, and animal and vegetable waste products.
                               502

-------
These  solids may  settle  out rapidly,  and bottom  deposits  are
often  a mixture of both  organic and inorganic  solids.  Solids  may
be suspended in water  for a time and  then  settle  to  the bed of
the stream or lake.  These solids discharged with man's wastes
may be inert, slowly biodegradable materials,  or  rapidly  decom-
posable substances.  While in suspension  suspended  solids
increase the turbidity of the water,  reduce light penetration,
and impair the photosynthetic activity of  aquatic plants.

Suspended solids  in water interfere with many  industrial  pro-
cesses and cause  foaming in boilers and incrustations on  equip-
ment exposed to such water, especially as  the  temperature rises.
They are undesirable in  process water used in  the manufacture  of
steel, in the textile industry, in laundries,  in  dyeing,  and in
cooling systems.

Solids in suspension are aesthetically displeasing.  When they
settle to form sludge deposits on the stream or lake bed, they
are often damaging to the life in the water.   Solids, when trans-
formed to sludge  deposit, may do a variety of  damaging things,
including blanketing the stream or lake bed and thereby destroy-
ing the living spaces for those benthic organisms that would
otherwise occupy  the habitat.  When of an  organic nature, solids
use a portion or  all of  the dissolved oxygen available in the
area.  Organic materials also serve as a food  source for
sludgeworms and associated organisms.

Disregarding any  toxic effect attributable to  substances  leached
out by water, suspended  solids may kill fish and  shellfish by
causing abrasive  injuries and by clogging  the  gills and respira-
tory passages of  various aquatic fauna.  Indirectly, suspended
solids are inimical to aquatic life because they  screen out
light, and they promote  and maintain  the development of noxious
conditions through oxygen depletion.  This results in the killing
of fish and fish  food organisms.  Suspended solids also reduce
the recreational value of the water.

Total suspended solids is a traditional pollutant which is com-
patible with a well-run  POTW.  This pollutant with the exception
of those components which are described elsewhere in this sec-
tion, e.g., heavy metal  components, does not interfere with the
operation of a POTW.   However, since a considerable portion of
the innocuous TSS may be inseparably bound to  the constituents
which do interfere with POTW operation, or produce unusable
sludge, or subsequently  dissolve to produce unacceptable POTW
effluent,  TSS may be considered a toxic waste.

POLLUTANT SELECTION FOR CORE WASTE STREAMS

The pollutant selection procedure was performed for the following
core groups of waste streams to select those toxic pollutants
that would be considered for establishing regulations for these
core wastewater stream groups:

     Rolling with Neat Oils Core Waste Streams
     Rolling with Emulsions Gore Waste Streams
     Extrusion Core Waste Streams
     Forging Core Waste Streams
     Drawing with Neat Oils Core Waste Streams
     Drawing with Emulsions or Soaps Core Waste Streams

Rolling with Neat Oils Core Waste Streams

The following waste streams will receive a pollutant discharge
allocation in the core of the Rolling with Neat Oils Subcategory:

     Roll Grinding Spent Emulsion
     Annealing Furnace Atmosphere Scrubber Liquor
     Sawing Spent Lubricant
     Miscellaneous Nondescript Wastewater Sources

The annealing furnace atmosphere scrubber liquor waste stream had
no toxic pollutants detected above the level considered achiev-
able by specific available treatment methods.   No specific
pollutant data were considered for the miscellaneous nondescript
wastewater sources.  The Agency did not sample the roll grinding
spent emulsion and sawing spent lubricant.  However, the charac-
teristics of these wastes are determined to be the same as the
rolling spent emulsion.  All three processes,  rolling, roll
grinding and sawing, require a lubricant to prevent excess wear
on the metal against metal surfaces and to aid by cooling the
surfaces.  Since the properties of the lubricants required are
similar between these three processes, the formulations for each
ought to be similar, therefore, the characteristics o£ one are
transferable to another.

Pollutants Never Detected.  The toxic pollutants listed below
were not detected in any samples from these wastewater streams;
therefore, they were not selected for consideration in
establishing regulations for these wastewater streams.

Rolling with Emulsions Core Waste Streams

The following waste streams will receive a pollutant discharge
allocation in the core of the Rolling with Emulsions Subcategory:

     Rolling with Emulsions Spent Emulsions
     Roll Grinding Spent Emulsions
     Sawing Spent Lubricants
     Miscellaneous Nondescript Wastewater Sources

No specific pollutant data were considered for the miscellaneous
nondescript wastewater sources.  Due to a lack of data,  the
rolling with emulsions spent emulsions, the roll grinding spent
emulsion, and the sawing spent lubricant are considered to be
similar.  The same pollutant selection is considered equally
applicable to both of these waste streams.  As discussed previ-
ously, the Agency did not sample the roll grinding spent emulsion
and sawing spent lubricant.  However, the characteristics of
these wastes are determined to be the same as the rolling spent
emulsion, therefore, the characteristics of rolling spent emul-
sions are transferable to the roll grinding spent emulsion and
the sawing spent emulsion.

Extrusion Core Waste Streams

The following waste streams will receive a pollutant discharge
allocation in the core of the Extrusion Subcategory:

     Extrusion Die Cleaning Bath
     Extrusion Die Cleaning Rinse
     Extrusion Die Cleaning or Press Scrubber Liquor
     Sawing Spent Lubricant
     Miscellaneous Nondescript Wastewater Sources
                               519

-------
No specific pollutant data were considered for the miscellaneous
nondescript wastewater sources.  For the extrusion die cleaning
or press scrubber liquor, no toxic metals were detected above
their analytical quantification level and above the level con-
sidered achievable by specific available treatment methods.  Due
to a lack of data, the toxic organics in the extrusion die clean-
ing or press scrubber liquor and the cleaning or etching scrubber
liquor are considered to be similar.  The same pollutant selec-
tion is considered equally applicable to both of these waste
streams.  As will be discussed in the section on pollutant selec-
tion for ancillary waste streams, no toxic organics were selected
for consideration in establishing regulations for the cleaning or
etching scrubber liquor wastewater stream.  Due to a lack of
data, the extrusion die cleaning bath and the cleaning or etching
bath are considered to be similar.  The same pollutant selection
is considered equally applicable to both of these waste streams.
As will be discussed in the section on pollutant selection for
ancillary waste streams, cadmium, chromium, copper, cyanide,
lead, nickel, and zinc were selected for consideration in estab-
lishing regulations for the cleaning or etching bath wastewater
stream.  As discussed previously, the Agency did not sample the
sawing spent emulsion.  The characteristics of this waste are
determined to be the same as the rolling spent emulsion, there-
fore, the characteristics of rolling spent emulsions are trans-
ferable to the sawing spent emulsion,

allocation in the core of the Drawing With Emulsions or Soaps
Subcateogry:

     Drawing With Emulsions or Soaps Spent Lubricants
     Sawing Spent Lubricants
     Miscellaneous Non-Descript Wastewater Sources

No specific pollutant data were considered for the miscellaneous
non-descript wastewater sources.  Drawing with emulsions or soaps
spent lubricants were only sampled at one facility; however, the
volatile organics and toxic metals were not analyzed in that
sample.  As discussed previously, the Agency did not sample the
sawing spent emulsion.  The characteristics of this waste are
determined to be the same as the rolling spent emulsion, there-
fore,  the characteristics of rolling spent emulsions are trans-
ferable to the sawing spent emulsion.  Due to a lack of data for
volatile organics and toxic metals in the drawing with emulsions
or soaps spent lubricants, the data used in the selection process
was for the rolling with emulsions spent emulsions and drawing
with emulsions or soaps spent lubricants wastewater streams
combined together.
