                                  ABSTRACT

          Investigations of on-land disposal of process and pollution
control residuals from the United States metal smelting and refining
industry were conducted.  This volume presents the results of studies of
the U.S. ferrous smelting and refining industry including iron and steel
(SIC 3312), iron and steel foundries (SIC 332), ferroalloys (SIC 3313),
and primary metal products not elsewhere classified (SIC 3399).   Volume
II of this report includes the results of investigations of hazardous
waste generation and treatment and disposal in the primary and secondary
nonferrous smelting and refining industry.  Volume I summarizes major
findings in both ferrous and nonferrous categories.  Characteristics of
each industry sector, including plant locations, production capacities,
and smelting and refining processes, have been identified and described.

          Land-disposed or stored residuals, including slags, dusts, and
sludges, have been identified and characterized by physical and chemical
properties.  State, regional and national estimates have been made of
the total quantities of land-disposed or stored residuals and potentially
hazardous constituents thereof.

          Current methods employed by the ferrous metals industry for
the disposal or storage of process and pollution control residuals on
land are described.  Principal methods include lagocn storage of sludges,
and open dumping of slags, sludges and dusts.  Methods of residual
treatment and disposal considered suitable for adequate health and
environmental protection have been provided.  Finally, the costs incurred
by typical plants in each smelting and refining category for current and
environmentally sound residual disposal or storage on land have been
estimated.

                                CONCLUSIONS

          The ferrous smelting and refining industry disposes or stores
large quantities of process and pollution control residuals on land.
These residuals are predominantly inorganic slags, sludges, and dusts
containing oxides and other compounds of iron, silicates, and trace
metals.  The only highly organic sludge encountered is decanter tar
sludge from iron and steel industry byproduct coke plants.  In addition
to slags, sludges and dusts, the iron and steel foundries dispose of
significant quantities of waste sand on land.  Significant quantities of
acid waste pickle liquor and waste oil are produced at iron and steel
plants and usually handled by contract disposal services for reclamation
or disposal.

          The principal potentially hazardous constituents found in
ferrous smelting and refining residuals are heavy metals including
chrome, copper, zinc, lead, and nickel, and fluorides.  Coke plant
wastes contain phenols, cyanides, ammonia, oils and greases.  Phenol and
cyanide appear to a much lesser extent in blast furnace dust and wet
scrubber sludges as well.  Foundry sands may contain phenol as a result
of the use of phenolic binders which are not degraded by process heat.
Some mill scales from steel plant rolling mills contain significant
amounts of oils and grease.

          The predominant practice used j.n the ferroalloy and iron and
steel industries for the disposal of non-recyclable slag and dust resi-
duals is open dumping.  Because the iron and steel industry generally
dewaters sludges before disposal, sludges are more often open dumped
rather than contained in lagoons.  The foundry industry produces relatively
small quantities of sludge and generally mixes them with waste sands and
dusts before land disposal.  The ferroalloy industry is more likely to
employ lagoons for containment of sludges.

          The iron and steel industry generally reclaims iron from slags
before land disposal or sale as road ballast or aggregate.  A much
higher percentage of blast furnace slag is sold because of lower density
and greater chemical stability than basic oxygen or electric furnace
slag.  Approximately 80% of mill scales generated in steel mills is
recycled to recover iron value.  Blast furnace dust is normally recycled
to sinter or blast furnaces while basic oxygen furnace dust is occasionally
recycled to sinter.   The high zinc content of electric furnace dust and
many basic oxygen furnace (EOF) dusts generally makes it impractical to
recycle these dusts.  The industry is attempting to develop technology
for accepting greater quantities of dusts and sludges as sinter or blast
furnace inputs.  In a similar manner the ferroalloy industry which
generally cannot accept dusts as furnace inputs because of trace metal
contamination is exploring technology for greater recycling of dusts.

-------
          The foundry industry directly recycles significant quantities of
moiii sund and reclaims significant quantities nf core sand for recycle.

          The presence of potentially hazardous constituents in slags,
Siudges, sands, and dusts has been shown including heavy metal and fluorides.
Solubility tests described in Appendix B of this report indicates that
some of these hazardous constituents may be leached from some wastes.
In general, slags were found to solubilize to a lesser extent than sludges
..,- uusts.  Process wastes have been categorized us potentially hazardous
or not hazardous based on the results of the solubility tests and con-
sideration pf physical (i.e. particle size) and chemical properties.

          Practices to protect ground and surface waters in the event of
demonstrated significant leaching of potentially hazardous constituents
include the use of lined lagoons for storage or permanent disposal of
sludges.  Leachable sludges which are dredged or pumped from lagoons or
settling pits and dumped on land can often be chemically "fixed" so that
leaching of heavy metals is prevented according to fixing chemical manu-
facturers.  Alternatively, sealing of soil in disposal areas with bentonite
or other sealants should prevent leachate percolation.

          For those slags, dusts, sludges, and or other land-disposed
or stored solid residues shown to, or suspected to solubilize toxic con-
stituents significantly, then soil sealing of disposal or storage areas
would be needed.  Collection of runoff from disposal dumps containing slags,
sludges or dusts with leachable heavy metals or other potentially hazardous
constituents may he needed.  Collected runoff would require treatment
before discharge or retention and evaporation in lagoons.

          Costs lor present and environmentally .nleijuaU1 potentially
hazardous wa •, 1 c treatment and disposal are given tor each smelting and
refining category.

                                INTRODUCTION

          This report is the result of study commissioned by the U.S.
Environmental Protection Agency to assess "Industrial Hazardous Waste
Practices in the Smelting and Refining Industry.   Concurrently, the
DSl.l'A is pursuing similar studies of other industry categories.  This
program is intended to provide the USEPA with as detailed and pertinent
information on the generation, management, treatment, disposal, and
costs related to wastes considered to be "potentially hazardous."
Such information will be used by the USEPA in developing guidelines or
standards for the management of hazardous wastes.

          Throughout this report whenever the terms "hazardous wastes" or
"potentially hazardous wastes" are used,  it should be kept in mind that
no final judgements are intended as to such classification.  It is
recognized and understood that additional information will be required
as to the actual fate of such materials in a given "disposal" or "manage-
ment" environment before a final definition of "hazardous waste" evolves
and is used.  As an example, for certain of the waste streams identified
in this report, the USEPA is currently supporting other studies designed
to investigate leaching characteristics in various soil and moisture con-
di tions.

                    FERROUS METAL SMELTING AND REFINING
          This section presents the results of investigations and analyses
of on-land disposal or storage of process and pollution control residuals
from the United States ferrous smelting and refining industry including
iron and steel,, iron and steel foundries, ferroalloys and ferrous metals
not elsewhere classified such as metal powders.  Characteristics of each
industry sector including plant locations, production capacities and
smelting and refining processes have been identified and described.

          Land disposed or stored residuals including slags, dusts, sands
and sludges have been identified and characterized physically and chemically.
State, regional and national estimates have been made of the total quantities
of land disposed or stored residuals and potentially hazardous constituents
thereof for 1974, 1977, and 1983.

          Current methods employed by the ferrous metals industry for the
disposal or storage of process and pollution control residuals on land
are described.  Principal methods include lagoon storage of sludges and
open dumping of slags, sludges, dusts and sands.  Methods of residual treat-
ment and disposal considered suitabls for adequate health and environmental
protection have been provided.  Finally, the costs incurred by typical
plants in each primary smelting and refining industry for current and
environmentally sound residual disposal or storage on land have been esti-
mated.

1.0       IRON AND STEEL

I.i.       INDUSTRY CHARACTERIZATION

          The United States steel industry is very large.  The industry
ranks third in the nation, behind the automotive and petroleum industries,
in the value of its total shipments and, with approximately 487,000
employees, is second only to the automotive industry in the number of
people on the direct payroll.   Over the decade since 1962, steel industry
?;.ies have increased 60%, from sales of $14.0 to over $22.0 billion
(.Ref. 1).  Steel mills may range from comparatively small plants to
completely integrated steel complexes.  Even the smallest of plants will
generally represent a fair sized industrial complex.  Because of the
wide product range, the operations will vary with each facility.

          Approximately ninety-two per cent of the 1972 total United
States annual steel ingot production was produced by fifteen major steel
corporations.  This total also represents 22.5% of the world total of
556,875,000 metric tons (625,000,000 tons).  Table 1 presents the pro-
duction breakdown by corporation.  Tables 2 and 3 list the number of
si eel plants by state, EPA regional, and national total iron and steel
capacity.  The capacity by each of the three major steel producing modes
(i.e. basic oxygen furnace, open hearth furnace, and electric furnace)
nre also given in these tables.

          Three basic steps are involved in the production of steel.
First, coal is converted to coke.  Second, coke is then combined with
iron ore and limestone and fired in a blast furnace to produce iron.
Third, the iron is purified into steel in either an open hearth or basic
oxygen,  or furnaces.  Electric furnaces remelt and refine predominantly
scrap iron and steel.  Further refinements include degassing by subjecting
the steel to a high vacuum.  Molten steel is usually cast into ingot
molds but the use of a process called continous casting is increasing
steadily.  These processes are discussed in more detail in Section 1.2.

          Coke plants are operated as parts of integrated steel mills to
supply the coke necessary for the production of iron in blast furnaces.
Nearly all coke plants today are byproduct plants, i.e., products such
as coke oven gas, coal tar, crude and refined light oils, ammonium
sulfato, anhydrous ammonia, ammonia liquor, and naphthalene, are produced
in mill it ion to coko.  A very smull portion of coke  is also produced in
the beehive coke process.  A byproduct coke plain consists essentially
of the ovens in which bituminous coal is heated, out of contact with
air, to drive off the volatile components.  The residue remaining in the
ovens is coke; the volatile components are recovered and processed in
the byproduct plant to produce tar, light oils, and other materials of
potential value, including coke oven gas.

] 2       WASTE CHARACTERIZATION

          This section contains descriptions of production technology at
iron and steel plants and the resultant byproducts or wastes which are
«, ithrr recycled, handled by contract disposers, or disposed of on site.
Estimates are given for the quantities of wastes and potentially hazardous
constituents thereof which are disposed of on land, either in lagoons or
dumps.

1.2.1     Process Descriptions

          Integrated steel mills perform all the operations required to
convert the principal raw materials of iron ore, limestone, and coal
into finished steel products.  The principal operations consist of raw
material processing, iron making, steel making, primary rolling or
roughing, and hot and cold finishing.  Additional operations might
include forging, annealing, tempering, tin plating and galvanizing.  The
interrelationships between the operations carried out in a typical large
integrated steel plant are shown in the flow diagram of Figure 1.
Smaller plants might lack the facilities for some of the operations
 ;hown,  such as sintering, continuous casting, tin plating and galvanizing.
The major operations are described in the following paragraphs.

          Sintering.   The sintering operation takes natural fine iron
ores and metallic fines derived from residues of other steel plant faci-
lities  (e.g., flue dust from the blast furnace and scale from hot rolling
mills)  and fuses them into pieces large enough to be charged into the
blast furnaces.  In a typical sintering machine the fine material is
mixed with coke breeze or powdered coal and spread on a moving bed.  The
mixture is ignited as it passes under an intense flame.  The reaction is
sustained by the combustion of the coke or coal as air is drawn downward
through the bed.  At combustion temperatures, the particles fuse together
into n caked layer which is usually quenched with air and broken into
pieces of the desired size.  Particulates collected by one or more of a
variety of emission control systems are generally recycled back into the
sintering process.  Therefore, no significant amounts of wastes are
generated at sintering plants.

          Coke .uid Byprodui 1  Product ion.   I'okr MTVI'S both .is a t'uol
and as a reducing agent in the making of iron.  To produce the required
coke, bituminous coal is heated to drive off Uiu volalile components.
Two methods of producing metallurgical coke are in use today, the byproduct
method and the beehive process, although the beehive process accounts
for less than two percent of all metallurgical coke produced.

          In the beehive process, the volatile components are burned
through the addition of control Jud amounts of .11 r  into the- coking chambers.
The heat generated by burning of the combustible volatilcs provides
energy for maintaining the distillation process.

          In the byproduct process, no air is admittea , o the coking
chambers, the heat for distillation being provided by the combustior, - *•
rue, gas in contact with the walls of the coke ovens.  The volatile^
dri/en off during distillation are piped from the coke ovens and processed
fer recovery of useful byproducts.  After coking is completed (16 to 24
r'n.-rs), the hot coke is pushed from the ovens into a waiting car which
transfers it to a quenching tower where it is cooled by water sprays.

          Iron and Steel Making.   In iron and steel making, fluxes are
I'.ilc'ed which combine with impurities to form slag   Fluxes include lime-
stone, lime, dolomite, und fluorspar.  Linn.- is often made onsite at the
steel plant by the calcination of 1imestono.  The dusts meliorated in tho
required crushing, screening, and handling of tho matorinls are generally
collected and recycled.

    i      Blast Furnace.   Almost all of the b;
-------
All three furnaces use limestone and/or fluorspar fluxes to facilitate
the removal of impurities as slag.

          For control of emissions from basic oxygen furnaces, the use
of high energy wet scrubbers appears to be predominant.  Of the ton
steel plants visited during this program, seven plants had EOF furnaces;
and of these plants, six were controlled by wet scrubbers.  One plant
used a dry electrostatic precipitator preceded by a wet spray system for
gas cooling.

          Five of the plants visited had electric furnaces.  Three of
these plants used dry baghouses for dust collection.  The other two used
a wet scrubber followed by a clarifier and vacuum filter for handling
the scrubber water.

          Four of the plants had open hearth furnaces and, in all cases,
emission control was handled by dry electrostatic precipitators.

          Thus, wastes from steel making consist of slag for all furnace
types, and dusts and/or sludges, depending on the type of furnace and
the associated emission control system.  For BOF furnaces, sludges
appear to be the most common form of pollution control waste, while for
electric furnaces and open hearths dry dust appears to be most common.
In addition to the above wastes, particulates called "kish" are released
to the air during the pouring of the molten pig iron.  In BOF shops,
thi^ material is commonly collected in baghouses.

          Ingot Molding and Rolling.   Molten steel is tapped from the
steel making furnaces into teeming ladles and then transferred to a
teeming area or to a continous casting area.  In the teeming area, the
molten steel is poured into ingot molds.  Upon solidification, the
ingots are placed in soaking pits to bring them to the desired uniform
temperature.  They are then rolled into billets, blooms, or slabs which
are blocks having different shapes and weights.  Wastes consist of slag
that accumulated at the bottoms of the soaking pits, scale generated in
the rolling operations and sludges from treatment of scale pit water.

          Continous Casting.   In continous casting, the molten steel in the
teeming ladles is cast directly into billets, blooms, or slabs, thereby
eliminating the need for ingot molds, soaking pits and primary rolling
described in the next paragraph.  As the castings leave the molds, they
are sprayed with cooling water.  As a result of coming in direct contact
with the steel, this water contains fine scale that is removed as sludge
during treatment of the water.  Coarser scale accumulates in settling nits.

          Rolling.    The billets, blooms, and slabs formed in the roughing
mill or in the continous caster are sent to the hot rolling mills where
they are converted into a wide variety of finished or semi-finished products,
including bars, rods, tubes, rails, structured shapes, sheets, and plates.
These hot rolling operations produce scale which is collected in pits.
Sometimes surface defects in billets, blooms and slabs are removed prior

I.::. :      DL sc >• Ljpjtioji of Waste Streams

          'I'h'r-- section describes the typos (if wastes associated with
«.-:.•(!', ct t>*,' ste<--l making processes previous I v described.  Generation
factors for each type of wastes are given as well as an assessment of
their potential environmental hazard.

-""i"' iJiid Byproduct Plants.   Wastes generated rcom coke and byproduct
cuke plants include waste ammonia liquor, ammonia still lime sludge and
decant or tank tar.  The relative amounts of t.'.ese wastes will vary
considerably from plant to plant depending on the specific design of the
byproduct recovery plant.

          W.'istc Ammoiua_ Li quor.    Ammonia is recovered from coke gas by
one of two methods.  In some plants ammonia is recovered in the form of
ammonium sulfate by passing the coke gas through dilute sulfuric acid.
'liii:-, produces a waste ammonia liquor generated at a rate of 190 kg/MT of
coke- produced or 125 kg/MT of steel produced based on the use of 0.66 MT
of c.oke for 1 ton of steel.  Waste ammonia liquor contains significant
con.c entrations of phenol and cyanide and is therefore considered potentially
hazardous.

          Ammonia Still Lime Sludge.   At other plants ammonia is removed
initially from the coke oven gas by spray cooling and scrubbing and sold
as a concentrated ammonia liquor.  Concentration of the liquor is achieved
in a ammonia still which produces a waste lime sludge formed as a result
of adding milk of lime to decompose ammonium salts.  Ammonia still lime
sludge along with decanter tank tar to be described is generated at a
rate of 0.28 kg/MT of finished steel product (dry weight).  This sludge
will contain significant concentrations of cyanide, phenol, and oils and
greases.  In solubility tests described in Appendix B ammonia still lime
sludge was found to leach significant concentrations of phenol and
cyanide (198 ppm Cn, 20 ppm phenol).  It is therefore considered potentially
hazardous.

          Decanter Tank Tar.   The spray cooling of coke oven gases also
condenses tars which are sent to a decanter tank where  lighter recoverable
oil fractions are decanted off.   The heavier tar goal-rated at a rate of
.'.3 kf,/MT steel along with ammoni.i still lime ;.lndi;c  is ^ent to open
dumps.  In solubility tests described in Appendix B de-cantur tank tar
was found to leach significant concentrations of phenol (500 ppm) and
oil and grease (198 ppm) and is therefore considered potentially hazardous.

          Wastes generated from iron and steel making include slags,
sludges and dusts.  The quantities and nature M" these residuals are
described in the following paragraphs as well as an assessment of their
hazardousness or non-hazardousness.

Blast Furnace.   Residuals from blast furnace processing of iron ore to
produce molten iron metal include slag, dus;s from dry air emissions
controls or sludge from wet air emissions controls.

                                     16

-------
          Slu£.   Blast furnace slag  is generated at a rate of 348 kg/MT
of  iron outjnit from the blast furnace or 250 kg/MT of finished stool.
It  is normally granulated by quenching the molten slap, with water.  This
produces sand size to  large chunks of a hard vesicular slug containing
predominantly silica,  lime, iron, sulfur and traces of minor metals
including chromium, manganese,  lead, copper and zinc.  In solubility
tests described in Appendix B blast furnace slag did not leach toxic
constituents in significant concentrations and is therefore not con-
sidered potentially hazardous.

          Oust.   Dust from dry emissions controls on blast furnaces
including baghouses and electrostatic precipitators is predominantly
iron oxide, silica and lime but contains significant concentrations of
chromium, copper, manganese, nickel, lead and zinc.  Concentrations of
these metals is significantly higher in dusts than in slag.  It is
generated at a rate of 16.2 kg/MT of blast furnace iron output or 11.7
kg/MT of steel product.   In solubility tests described in Appendix B
blast furnace dust did not leach toxic heavy metals significantly and is
therefore not considered  potentially hazardous at this time.

          S ludge.   Sludge from wet emissions controls on blast furnaces
including wet electrostatic precipitators, venturi scrubbers, and spray
towers is also predominantly iron oxide, silica and lime and contains
significant concentrations of the trace metals chromium, copper, manganese,
nickel, lead and zinc.  Concentrations of these metals is significantly
higher in sludges than in slags.  It is generated at a rate of 24.4 kg
per metric ton of blast furnace iron output or 17.6 kg/MT of steel (dry
weights] .   In solubility  tests described in Appendix B blast furnace
sludge was not found to leach toxic constituents in significant concentrations
and is therefore not considered a potentially hazardous waste.

Basic Oxygen Furnace (BOF) .   Residuals from BOF processing of iron,
scrap and alloying metals to produce steel while reducing carbon sulfur,
phosphorus and other impurities, include slag, dusts and sludges.
                  A dense slag containing large amounts of silica, iron and
 lime, minor amounts of sulfur and phosphorus and significant concentrations
of the trace metals chromium, copper, manganese, nickel, lead and zinc is
generated at a rate of 145 kg/MT of steel output.  In solubility tests des-
cribed in Appendix B blast furnace slag was not found to leach significant
concentrations of toxic constituents and is therefore not considered poten-
tially hazardous.

          I)i£st.   Fine dust from dry air emissions controls is mainly iron
oxide, silica oxide and lime but also contains significant concentrations
of trace metals  including chrome, copper, manganese, nickel, lead and zinc.
Dust is generated at a rate of 16 kg/NTT of steel product.  Data indicates
zinc and lead are more concentrated in dusts and sludges whereas chrome
tends to stay with slag.   In solubility tests described in Appendix B
BOF sludge did not leach appreciable concentrations of toxic constituents.
The low solubility of BOF sludge indicates that dust will also not leach
                                     17

-------
     r icai'.tiv,  Por this reason BOF dust is not considered potentially
     dous at this time.

          Sludgj.;.   Sludge from wet control of air emissions from BOF's
is a]so predominantly  iron oxides, silica oxide and lime with small but
significant concentrations of the trace metals r.hrome, copper, manganese,
iK'kel, lead and zinc.  It is generated at a rate of 17.3 kg/MT of steel
,,-roJuct (dry weight).  In solubility tests described in Appendix B BOF
sludge did not leach significant concentrations of toxic constituents
and is therefore not considered potentially hazardous at this time.

Open Hearth Furnaces.   Residuals generated from open hearth furnaces
include slag, dusts and sludges.

          Slaji-   A dense, hard slag is generated at a rate of 243 kg/NTT
of sti'ol product..  It  is mainly iron oxides, silica oxide and lime, with
minor amounts of sulfur and phosphorus compounds.  Trace metals present
in significant concentrations include chromium, copper, manganese,
nickel, lead and zinc.  In solubility tests described in Appendix B
toxic constituents did not leach to a significant extent.  Open hearth
slag Is therefore not considered hazardous at this time.

          Dust.   Dust from dry emissions control is generated at a rate
of 13.7 kg/MT of steel product.  It is predominantly iron oxides, silica
oxides and lime but contains significant concentrations of chrome,
copper, manganese, nickel, lead and zinc.  As with BOF furnaces data
indicates that lead zinc, and to a lesser extent copper concentrate to a
greater extent in dusts whereas chrome stays with the slag.  Solubility
tests described in Appendix B showed no appreciable leaching of toxic
constituents.  For this reason open hearth dust is not considered potentially
hazardous at this time.

          Sludge.   None of the plants visited or surveyed during this
study used wet emissions controls on open hearth furnaces.  Thus no
generation factors could be developed or chemical analyses made.  The
sludge would be similar in composition to dust and would not be expected
to leach significantly so as to be considered hazardous.

I-ledric Furnaces.   Residuals from electric furnaces include slag, dust
and sludge.

          Slag.   A dense hard slag is generated at a rate of 120 kg/NfT
of steel.   It is composed principally of iron, silica and calcium compounds
with minor amounts of sulfur and phosphorus compounds.  Trace metals
include chromium, copper, manganese, nickel, lead, and zinc.  In solubility
tests described in Appendix B toxic constituents did not leach significantly.
Electric furnace slag is therefore considered non-hazardous at the
present time.
                                     18

-------
                  Dust from dry emissions controls is generated at a
 rate of  1J.K kg/Ml' of steel.   It is principally iron and silica oxides
 ;nid lime witli significant concentrations of the trace metals chromium,
 copper, manganese, nickel, lead, and  zinc.  Zinc, lead and copper are
 much more concentrated in dusts and sludges than in slag.  In solubility
 tests described in Appendix B  lead was found to leach at appreciable
 concentrations  (150 ppm).  Electric furnace dust is therefore considered
 potentially hazardous.

          Sjudge.   Sludge from wet emissions controls is generated at a
 rate of 8.7 kg/MT of steel product.   It is comprised principally of iron
 and silica oxides and lime and contains significant concentrations of
 the trace metals chromium, copper, manganese, nickel, lead and zinc.  In
 solubility tests described in Appendix B electric furnace sludge leached
 chromium (94 ppm) and lead (2.0 ppm)  in significant concentrations.
 Floctric furnace sludge  is therefore  considered potentially hazardous at
 this time.

 Soaking Pits.   Soaking  pit slag of gravel to boulder size is generated
 at a rate of 35.2 kg/MT  of steel.  It is composed principally of iron
 and contains significant concentrations of trace metals including
 chromium, copper, manganese, nickel,  lead and zinc.  In solubility tests
 described in Appendix B  this slag did not leach significant concentrations
 of toxic metals.  It is  therefore considered non-hazardous at this time.

 Mill Sludges.   Mill sludges are produced from a number of steel plant
 facilities as a result of water pollution control operations,,  Generation
 factors for various mill sludges are as follows:

 Primary Mills (production of ingots,  slabs, billets  1.87 kg/MT steel
 Continuous Casting Mill  -  0.104 kg/MT steel
 Hot Rolling Mill - 1.74  kg/MT steel
 Cold Rolling Mill - O.lb kg/MT steel
 Tin Plating Mill - 5.32  kg/MT steel
 Galvanizing Mill  10.8 kg/MT steel

          Samples of two of the above types of sludges were obtained and
 chemically analyzed including hot rolling mill sludge and tin plating
mill sludge.  Both of these sludges contained significant concentrations
 of trace metals including chromium, copper, manganese, nickel, lead,
 zinc and oil and grease.

          Solubility tests were not conducted on mill sludges.  They are
believed to be susceptible to leaching of oil and grease and quite
possibly some toxic metals because of the presence of these constituents
and fine size of sludge particulates.
                                     19

-------
Mi]_.' bj._j_Lf.-s    Mill scales containing over 50% iron are generated froti*
the L\,[ Lowing mi 1 Is :

          Primary Mills  44.9 kg/MT steel
          Continuous Casting Mills  8.7 kg/MT steel
          Mot Rolling Mills  18.3 kg/Ml1 steel
          Cold Rolling Mills  0.052 kg/Ml steej

          Mill scales contain over 50% iron a& well as small but significant
concentrations of trace metals including chromium, copper, manganese,
nickel, lead and zinc.  Mill scales can also contain as much as 0.4% oil
and grease. Oil and grease can be leached from mill scale and pose a
threat of ground water contamination.  For this reason mill scales are
considered potentially hazardous at this time.

l'k-klo_ I,iq_uors.   Acid pickle liquors (HOI, H~SO.) are used in cold
rolling mills and galvanising mills to clean iron and steel metal surfaces.
Spent uc ul is generated at a rate of 22.8 kg/MT steel from cold rolling
mills and S.17 kg/MT steel from galvanizing mills.  Waste pickle liquor
lontains  about 4-bl, acidity and large concentrations of dissolved and
.uibponded iron.  Chromium, copper, nickel, lead and zinc are also present
in minor concentration (less than 20 ppm).  The high acidity (pH less
th;'n 1.0) of waste pickle liquor and resultant solubilization of toxic
metal constituents are reasons  why waste  pickle  liquor  is  considered
potentially hazardous.

1.2.3     Waste Quantities

          During the conduct of this study, intensive sampling and
chemical  analyses .of steel plant residuals were carried out.  Ten steel
plants located in the North Central and Great Lakes region of the United
States provided personnel to obtain daily samples of steel plant production
and pollution control residuals, including slags, sludges, dusts, scales,
and pickle liquor.  These samples were shipped to the Calspan Laboratory
at Buffalo, New York, where the daily samples were composited into
weekly samples and then chemically analyzed.  Steel plant residuals were
therefore well characterized as to average chemical content and variability
in composition.  Results of chemical analyses from the ten steel plants
are given in Appendix A.

          Table 5 gives generation factors for the various residuals
from iron and steel production as well as concentration factors for
potentially hazardous constituents.  These factors were computed by
averaging aii available data collected from the 10 iron and steel plants
visited on generation rates and chemical analyses data from collected
residuals samples of slacs, sludges, dusts and other wastes.

          Using the residuals generation factors given in Table 5 the
yearly amount of residuals generated from a typical integrated steel
plant producing 2,500,000 MT of molten steel as described in Table 4
were estimated.  Quantities of potentially hazardous constituents were
also calculated for the typical integrated plant.  These estimates are
given in Table 6.                    20

          Using state-by-state production capacities as previously given
and waste generation and hazardous constituent factors per unit of
product as previously given in Table 5 estimates were made of the state,
regional, and national land-disposed wastes and hazardous constituents
from iron and steel production.  These estimates are given in Tables 7a
to 71 for 1974, 1977 and 1983.  E-xtrapolations of waste quantities to
1977 and 1983 were based on an annual growth rate of the steel industry
(and accompanying residuals generation) of 2.1% from 1974-1977 and 2.5%
from 1974 to 1977.  This compares with annual growth of 2.5% predicted
by the  industry over the same period (Reference 9).

          Tables 7a to 7e contain estimates of the total quantity of
slags from all sources (blast furnace, BOF, open hearth, electric furnaces,
soafcjng pit) which are or which will be generated in the iron and steel
industry in 1974, 1977, and 1983.  Although practices may vary widely
from plant to plant it is estimated that approximately 90% of generated
slag is processed for recovery of contained iron and steel and then sold
for use as road fill building aggregate and other purposes.  It may be
stored  for many months before use.  The remainder is open dumped.

          Tables 7d through 7f gives estimates of sludges generated from
all sources in the iron and steel industry for the years 1974, 1977, and
1983.  Approximately 55 percent of the total sludge generation originates
from wet scrubbers of the blast furnace and is considered non-hazardous.
Approximately 70% of blast furnace sludge is recycled to the sinter strand
for recovery of iron.

          Approximately 20% of the sludge estimated in Tables 7a to 7c
originates from wet emissions controls on BOF furnaces, 10% of which is
recycled to sinter strands.  In total some 75% of estimated sludge
generated is from blast furnaces plus BOF furnaces and is not considered
potentially hazardous.

          The remaining 25% of the sludge estimates given in Tables 7d
through 7f consists of sludges from electric furnaces, galvanizing mills,
primary and secondary rolling mills, lime pit sludges, and tin mill
sludges.  These sludges are considered potentially hazardous.

          Tables 7g through 7i contain estimates of the total quantities
of dust generated by the iron and steel industry for 1974, 1977 and 1983
through dry emissions controls on blast furnaces.  Approximately 57% of
the state,  regional and national estimates consists of blast furnace
dust.   Approximately 90% of blast furnace dust is recycled to the sinter
for iron reclamation with the remainder being placed on land dumps.
Blast furnace dust is not considered potentially hazardous.

          Approximately 12% of the dust generated in the iron and steel
industry is from electric furnaces and is considered potentially hazard-
ous.   Electric furnace dust is not presently recycled.  The remaining 31%
of the dust  quantity estimates given in Tables 7g through 7i consist
predominantly of BOF dust with a small percentage of open hearth dust.
BOF dust and open hearth dust are not considered potentially hazardous.
                                     2.S

-------
          Tables 7j through 71 contain estimates of quantities of scalt
    .-atod i" tin' iron aod steel industry from hot rolling mill, cold
rolling mills, primary mills, and continuous casting mills.  It is esti-
mated tli.it MO'i of mill sealos uro recycled for roclumat ton of  iron
co i, int.  The presence of high contents of oil and grease prevents
complete recycle, and for the same reason causes mill scales to be a
danger to the environment, and be considered potentially hazardous.

          Tables 7m through 7o contain estimates of the quantities of
spe.it pickle liquor (dilute solutions of sulfuric or hydrochloric acid
containing iron oxide and iron metal particles and traces of other
metals) generated in the iron and steel industry.  They are normally
disposed of by contract disposal services but may be regenerated for
reuse.  Pickling liquors are considered potentially hazardous.

          Generation of slags, sludges, and dusts follows production
patterns.  The largest producers of total iron and steel residuals and
potentially hazardous wastes from the iron and steel industry  are the
states of Pennsylvania, Ohio, and Indiana followed by Illinois, Michigan
and New York in that order.  Alabama, West Virginia, California, and
Utah aiso generate significant quantities of total and hazardous wastes.

1.3       TREATMENT DISPOSAL TECHNOLOGY

1.3.1.    Current Treatment and Disposal Practices

          This section will describe the prevalent methods used by the
iron and steel industry for the treatment and disposal of all  waste
types be they considered hazardous or non-hazardous.  Sections 1.3,2
through 1.3.4 will present more detailed discussions of the technologies
used to treat and/or dispose of those waste streams which are  considered
to be potentially hazardous.  Waste types are discussed with reference
to the plant facilities from which they originate.

Coke Plant.    Land disposed wastes from the coke plant of an integrated
steel facility includes waste ammonia liquor, anunonia still lime sludge
and decanter tank tar.  All of these wastes are considered potentially
hazardous because of the presence of phenols, and cyanides which are
susceptible to leaching.  The ususal treatment of waste ammonia liquor
is input to biological waste-water treatment plants.  This is environ-
mentally acceptable since the toxic constituents (phenol, cyanide) will
be detoxified in the bjologicul treatment.  Sonietimcs this waste is dis-
posed of in deep wells.

          Ammonia still lime '.ludge and decanter tank tar are  normally
disposed of by open dumping which is not environmentally acceptable
because of the suspei ti li i1ity ID leaching of phenol, cyanide and oils.

Blast Furnace.   Residuals from blast furnaces include slag, dust from

many months or years before use for these purposes,  i;i;io dust contain'-
significant eo centration of  iron and is normally  sent to sinter strand
to ',r agglomerated prior to reprocessing for iron  recovery.  Sludge  from
wet emissions control is also sent to the sinter facility for agglomera-
ti.,. ..riM- to reprocessing for iron recovery.

          All of the blast furnace residuals (i.e. slag, dust, sludge) are
considered non- hazardous.  Fluorides may leach to  the extent of a few parts
oer million from these materials which is noi considered sufficient  to pose
an environmental threat.
™-_li!jL£l1^f£2.>   Residuals from basic oxygen  furnaces include slag,
dusts t*rom dry emissions controls, sludges from wet  emissions controls and
kish from metal pouring.  Basic oxygen furnace slag  is usually open dumped
after recovery of metal lies.  This practice is adequate since basic oxygen
furnace slag is not considered potentially hazardous at the present
time.

          Dusts and sludges from emissions controls  are usually open dumped
as is kish.  This practice is adequate since none of these wastes are con-
sidered potentially hazardous at the present time.

Open Hearth Furnaces.  Slag from open hearth furnaces is usually open
dumped after processing for recovery of metal lies.   Open hearth dusts from
emissions controls are open dumped and are often wetted down before dis-
posal to prevent blowing. At some steel plants open  hearth dusts and BOF
dusts are recycled to the sinter.  Disposal practices are adequate since
these wastes are considered non-hazardous at the present time.

Electric Furnaces.   Residuals from electric furnaces include slag, dusts
from dry emissions controls and sludge from wet emissions control.  Slag
is usually open dumped after recovery of metallic^.  .-'• small amount of
slag (approximately 101,) is used as road fill or railroad track ballast.
These methods are adequate since electric furnace slug is not considered
potentially hazardous.

          Dusts from dry emissions control and sludge from wet emissions
control can leach potentially hazardous heavy metals as previously dis-
cussed.  Open dumping of these wastes as currently practiced is environ-
mentally inadequate.

Soaking Pits.   Slag is the only waste generated at  the soaking pits.
It is generally broken into chunks and hauled to open dumps.  This practice
is adequate since this waste is not considered potentially hazardous.

Mill Sludges.   This category of residuals includes  sludges from various
mill operations at an integrated steel plant including primary mills
which produce ingots, slabs and other primary steel  shapes, continuous
casting mills, hot rolling mills, cold rolling mills, galvanizing mills,
and tin plating mills.  Sludges from these nulls are produced as a result
of water pollution control operations including oil  and grease removal,
flocculation and settling of particulates, and pi I adjustment.
                                     42

-------
          All of the above sludges are considered potentially hazardous
because of possible leaching of hazardous constituents including chro-
mium, copper, nickel, lead, zinc and oil and grease.

          Currently the most prevalent management, of the above sludges
is open dumping except for tin plating sludges which arc put in unlined
lagoons.  These practices are inadequate because of the danger of toxic
heavy metal  leaching through permeable soils to groundwater.

Mill Scales.   Mill scales containing over 50% iron are generated in
primary and  hot rolling mills, continuous casting mills, and cold rolling
mills.  Scales from primary and hot rolling mills and continous casting
mills are recycled to the sinter or blast furnace for iron recovery.
This practice is environmentally sound since land disposal is precluded.

          Scale from cold rolling mills is often highly contaminated
with oil which discourages recycle to the sinter because of hydrocarbon
emissions in the sinter.  Normal disposal is by open dumping.  This
practice is  not environmentally adequate because of the possible movement
of oil and grease through permeable soils to groundwaters or surface
waters.

1'Lckle Liquors.   Currently the prevalent practice employed by steel
plants for handling of waste pickle liquor is the service of outside
contract disposal services who generally neutralize the acid before
disposal in  unlined lagoons.  Disposal in unlined lagoons is inadequate
if heavy metals leach from the sludge formed from neutralization and
percolate through permeable soils to groundwater.

1.3.2     Present Treatment and Disposal Technology (Level I)

Coke Plant.   Wastes from coking operations and associated byproduct
production which are considered potentially hazardous include waste
ammonia liquor, ammonia still lime sludge and decanter tank tar.  Treatment
of ammonia liquor in a biological treatment plant is adequate since des-
truction of potentially hazardous constituents (i.e. phenol, cyanide) is
achieved.  Inputs of these wastes to the biological treatment plant must
be sufficiently dilute so as to not interfere with normal biological
activity.  Deep well disposal of waste ammonia liquor is adequate only
when done according to EPA guidelines as stated in EPA Administrator's
Decision Statement No.  5 dated February 6, 1973 (Reference 10).

          Ammonia still lime sludge and decanter tank tar are presently
open dumped.  This practice is environmentally inadequate because of the
danger of toxics including phenol,  ammonia, or cyanide leaching and
percolating to ground or surface water.

Electric Furnaces.    Residuals from electric furnaces which are con-
sidered potentially hazardous include emission control dusts and sludges.
Present disposal of dusts and sludges is open dumping.  This practice is
environmentally inadequate because of the danger of heavy metal leaching
through permeable soils to groundwater or surface water.

                                     43

                Potentially hazardous sludges are generated from wate,
  _
pollution control operations in primary mills, continuous casting mills,
hot roir:iig mills, cold rolling mills, galvanizing mills and tin plating
mil's.  Present treatment and disposal is open dumping which is environ-
T.e-r'Tilly inadequate because of the threat of heavy metal and oil or grease
Mill S^JJjjJ^-   Potentially hazardous mill sculoi nro generated in primary
,iixl hot rolling mills, continuous casting mills and cold rolling mills.
The .scale from all of these operations excepting cold rolling mills is
normally recycled to the sinter for iron recovery and is environmentally
adequate.  Highly oil contaminated scale from cold rolling mills is
presently open dumped.  This practice is not environmentally adequate.

Pickle Liquor.   Present treatment and disposal technology generally
consists of disposal by contract disposal companies who neutralize the
acid pickle liquor and leave the neutralization sludge in unlined lagoons.
Some steel plants dispose of pickle liquor by deep weJl disposal.  The
use of unlined lagoons is not environmentally adequate because of the
danger of toxic heavy metal leaching through permeable soils to groundwater
or surface waters.  Deep well disposal is adequate when done in accordance
with HPA guidelines.

1.3.3     Best Technology Currently Employed (Level II)

Coke Plant.   Level II technology for treatment and disposal of waste
ammonia liquor, ammonia still lime sludge and decanter tank tar is the
same as Level I and is inadequate except for deep well disposal of
pickle liquors which is adequate.

Electric Furnaces.   Level II technology for treatment and disposal of
potentially hazardous electric furnace dusts and sludges is the same as
Level I (i.e. open dumping) and is inadequate.

Mill Sludges.   At approximately 5% of the steel plants sludges from
primary and hot rolling mills are recycled through the sinter for iron
recovery.  This precludes land disposal and is therefore environmentally
adequate.

          Colt! rolling mill and galvanizing mill shuh'rs .m> open dumped
which is inadequate for environmental protection.

          At  some plants tin plating mill water treatment sludge is
reprocessed for tin recovery.  This is environmentally adequate.

Mill Scales.   Level II treatment and disposal tcchnolog) for mill
scales from primary mills , continuous casting mills, hot rolling mills,
and cold rolling mills is the same as Level I.
                                     44

-------
Pickle Liquors.   At a few steel plants spent pickling liquor is processed
for reclamation of sulfuric acid or hydrochloric acid and reuse in the
pickling operations.  The iron oxide or iron sulfate residues can be
recycled for recovery of iron.  This practice is environmentally adequate.
Deep well disposal of pickle liquors according to EPA guidelines is
adequate.

1. .3.4     Technology to Provide Adequate Health and Environmental
          Protection (Level III)

Coke Plant..    Biological treatment of waste ammonia liquor from the
byproduct coke plant will detoxify toxic constituents including phenol,
cyanide, and ammonia if present in low concentrations.  Solvent recovery
and ammonia stripping will normally precede biological treatment of
ammonia liquor.  Deep well disposal of pickle liquors in accordance with
L;PA guidelines is adequate for environmental protection.

          Sealing of permeable soils at dump sites to prevent leaching
of phenol, cyanide, or ammonia from lime sludge or decanter tank tar, or
collection and treatment of leachate constitutes Level III treatment and
disposal technology.

1:1ectric Furnaces.   Sealing of permeable soils at dump sites for disposal
of sludge or dust, from control of emissions from electric furnaces or
collection and treatment of leachate will be necessary for adequate
environmental protection.

Mill Sludges.   If primary or hot rolling mill sludges are not recycled
to the sinter, chemical fixation would be required prior to open dumping.
Chemical fixation of cold rolling and galvanizing sludges would be
required before open dumping.

          Metal reclamation from tin plating sludge would qualify as
Level III technology.   If this sludge is lagoon disposed, the use of
lined lagoons would be needed for adequate environmental protection.

Mill Scales.    If mill scales are recycled to the sinter adequate environ-
mental protection is assured.   If mill scales are open dumped the use of
bentonite or other soil sealants would be required to prevent percolation
of toxic heavy metals or oil and grease,or collection and treatment of
leachate would be necessary.

Pickle Liquor.    Processing of spent pickle liquor to reclaim hydrochloric
or sulfuric acid and metallic value (i.e.  iron),or deep well disposal
according to EPA guidelines is Level III technology.

          Tables 8a through 8f summarize features of Levels I, II and
III treatment and disposal technologies for potentially hazardous wastes
from the iron and steel smelting and refining industry.

i.-i       COST ?t:,AifSIS

          In the last section various treatment and disposal technologies
currently employed or considered for adequate health and environmental
protection were described.  Tjie costs of implementing this technology for
n typical integrated iron and steel mill complex are estimated in this
sect;on.  Costs of land disposal from individual operations such as steel
fur ;r^fs and rolling mills are also given.  The exemplary plant has an
annual capacity of 2,500,000 MT of steel and is assumed to operated 350
days per year.  Facilities at the plant include the operations given in
Table 4 and generate the wastes listed previously in Table 5.  All disposal
 dtts are situated on semi-industrial land.

          Dust

          Dust results from blast furnace, basic oxygen furnace and
electric furnace operations.  Dust from the blast furnaces is recycled
to the sinter plant.  No disposal cost is incurred.  The dust-from the
basic oxygen furnace operations amounts to only 288 MT (222 m )/year.
It is not considered hazardous.

Electric Furnace Dust.   Dust from the electric furnaces considered poten-
tially hazardous (7,500 MT or 4165 m /yr) is hauled to an on-site dump.
This requires 1 hr/day of front loader and truck time plus 40 hrs/yr of
nulldozer time at the dump.  The dust is piled to a height of 5 m.  The
dump area is sized to hold 20 years of waste and extends over 1.7 ha.

          Sludge wastes are generated by all operations except by the
electric furnaces  (where a dry control system is assumed) and the soaking
pits.

Coke Oven Sludge.   Ammonia still  lime sludge (6,160 NfT or 5,135 m /yr) is
produced at  the coke ovens.  The sludge is disposed at a dump.  One hr/day
of  frontloader and truck time are  needed for loading and transporting the
sludge and 50 hrs/yr of bulldozer  time at the dump site.  The sludge is
piled to a height of 5 m.  The dump occupies 2.1 hectares and accommodates
20  years of  waste sludge.

Primary and Other Hot Rolling Mill Sludge.   The primary and other hot
rolling mills produce 5739 MT of sludge per year.  The scale wastes
generated by these operations are recycled to sinter on the blast furnace.
However, about 2 percent of the scale, containing oil contaminants, is
skimmed off and disposed with the sludge.

          The total yearly waste disposed is about 7,750 MT or 4840 m .
Loading and hauling require 1 hr/day of front loader and truck time, and
50 hrs/yr of bulldozer time is assigned at the dumpe site.  The dump
occupies 1.9 ha.

          Scale

          Scale is produced by primary and hot rolling mills and the cold
rolling mills.  Practically all of the scale of the former is recycled to
sinter or blast furnaces.  No disposal costs are incurred.  Scale from the
cold rolling mill is land disposed together with the sludge from that opera
tion.  No separate costs are incurred.
          Waste pickle liquor results from cold rolling and galvanizing mill
operations.  The liquor is treated and disposed of by an outside contractor
at a cost of $10.55/m  ($.04/gal).

          No capital costs are incurred.  The annual cost is $149,010.

          Waste Ammonia Liquor

          Waste ammonia liquor is normally not land disposed.  It is normally
detoxified in a biological treatment plant as a minor flow.  Occasionally it
is disposed of in deep wells.  The associated costs of deep well disposal
were not ascertained since no land disposal is considered as Levels I, II and
III treatment and disposal technology.

          Dust

          Dust disposal and associated costs are the same for Level II as
Level 1.

          Sludge

          Sludge from the Mast furnaces, basic oxygen furnaces and primary
and hot rolling mills can be recycled to sinter depending on its composition.

          Tin plating mill sludge in some plants has a sufficiently high
metal content so that it can be sold to an outside contractor for metal
reclamation.  We were unable to obtain information on prices paid by
reclaimers for the sludge.  This treatment method would eliminate the need
for the lagoon specified for Level I and its associated costs.  Level II
treatment for the other sludges is the same as for Level I.

          Waste PickJe Liquor

          Acid regeneration is the Level II treatment for waste pickle
liquor.  Reference 2 indicates a cost of $13/nf of waste treated.  This
cost is included as an annual cost.  It includes the amortization of capital
treatment plant investment.  Acid regeneration results in an annual cost
of $183,610 which is about a $35,000 increase over the Level I treatment cost.

          Incremental changes resulting from the implementation of Level II
technology are shown below.

          Level III treatment of waste pickle liquor consists either of
acid regeneration or neutralizing the waste by lime treatment, allow for
settling of the sludge in a lined lagoon followed by chemical fixation and
land disposal of the sludge.  Acid regeneration involves no additional costs
beyond those listed under Level II treatment.  Costs for the other alternative
is shown in Table 9.

          The total annual waste liquor.amounts to 15,100 MT.  This results
in the formation of 6,285 MT or 4,910 m .of sludge.  The selected lagoon size
Is 10,000 m  and it assumed that 4,910 m  of sludge are dredged annually.
The removed sludge is chemically fixed and hauled to a dump site.

          A J3(> I/min slurry pump is used for dredging.  The pump is operated
3f»0 lirs/yr and 400 hours of labor are assigned to its operation.  Loading
and hauling of the sludge to the dump site requires 2t>5 hrs/yr of front
loader and truck time and 50 hrs/yr of bulldozer time at the sludge dump.

the waste pickle liquor is considered part of the water treatment system
and its cost is not included.

          Summary costs for Level I, II and III waste treatments for an
integrated steel plant are given in Table 10.  Annual costs for Levels I
and II disposal of potentially hazardous wastes are estimated as $7,570,000
which represents less than 0.1% of the estimated 1973 sales value.
Annual costs for Level III technology (i.e. adequate for environmental
protection) are estimated as $12,930,000 or 0.15% of estimated 1973 sales
value.

1.0       IRON AND STHEL TOUNDRUiS

.M       INDUSTRY CHARACTERIZATION

          Die three major groupings of ferrous castings are gray and
auci.i.'t, iron castings, malleable iron castings, and steel castings.  While                   ^
specific procedures might vary from foundry to foundry, the overall opera-
tions for producting castings of all three types are essentially the same
tnd include metal melting and pouring, casting shakeout and cleaning and
ti'iishing.

          There are about 2000 foundries in the U.S. producing ferrous
castings.   There is great variability in plant si'.e with monthly capacities                  ^
ranging from 20 net tons to over 10,000 net tons.* It is important to note
that only about 60 percent of all castings produced in the United States
are covered under SIC 332 (Iron and Steel Foundries).  The remaining 40
percent are produced under other SIC categories, such as SIC 3714  (Motor
Vehicles), SIC 3541 (Machine Tools), etc.
                                                                                             •
          The production data and waste data presented in this report
represents only those operations covered under SIC 332 which are within
the primary metal smelting and refining industry.

          The 1973-74 directory of members of the Gray and Ductile Iron
Founders Society, Inc. lists 186 foundries.  The monthly average production                  9
of these foundries was calculated to be about 1125 MT of finished  castings
giving an average annual production of 13,500 MT.  Using data from "The
Metal Casting Industry Census Guide" (1972 Edition, published by Penton
Publishing Co., Cleveland, Ohio), the average annual production for all
gray and ductile iron foundries (an estimated 1300 to 1500 foundries) was
calculated to be about 9,250 MT.  Thus, a reasonable capacity figure for                      ^
a typical gray and ductile iron foundry plant would be about 11,000 net
tons per year.

          Steel foundries average about 5,440 MT of capacity per year and
malleable iron foundries average about 12,700 MT per year.                                   ^ i

          Table 11 gives state by state, regional, and national shipments                      *
of the various type of ferrous castings for 1973.  These figures are                           ;
believed to reflect 1973 capacity.  Iron and Steel foundries                                 , <
are concentrated in states heavy in manufacture of iron and steel  and                          \
automobiles and heavy industrial equipment which are principal consumers                       I
of foundry castings.                                                                           i

          While specific procedures might vary from foundry to foundry,
i he iwrall operations Tor producing  iron castings, malleable iron
<.;.ting;., arid stvol castings arc essentially the same and include:  sand
preparation, mold and core making, metal melting and pouring, casting
shakeout, and cleaning and finishing.  The interrelationship between
major operations in a typical foundry is shown in Figure 2.  Also shown
are the major sources of solid wastes.  Although not all foundries
practice sand reclamation, its use has become sufficiently widespread in
the industry to require its inclusion in Figure 2.

          Clay bonded molding sands are prepared by mixing silica sand,
organic additives, bentonite clay and water together.  Some foundries
use olivine, zircon, chromite, biasill or other aggregates instead of
silica sand.  Carbonaceous material in the amount of 2 to 10 percent is
also added to the molding sand as may be required to impart special
properties.  Materials in this category include finely ground bituminous
coal, ground corn flower, fuel oil, and finely ground cellulose material.

          The molds are made by packing the molding sand around previously
made patterns to form the required shapes.  For castings having hollows
or recesses, cores are required to complete the mold.  Since the cores
must be removed after the castings have solidified, the core sands have
special properties that facilitate their removal.  The desired properties
are achieved through the use of special binders, the most common of
which are: (1) combinations of vegetable, fish and petroleum oils; (2)
phenol formaldehyde resin, (3) sodium silicate; (4) phenolic isocyanate;
(5) alkyd isocyanate; and (6) mixtures of urea and furfural alcohols.
The first item is generally baked to promote hardening, and items 2 and
6 are generally heat-cured.  The difference is that baking is done at
the rate of approximately one hour per inch of thickness while curing is
done in a matter of 30 to 60 seconds at approximately the same temperature.
In the case of sodium silicate binders, hardening is achieved by forcing
CO  gas through the sand.  For the isocyanate binders setting occurs at
room temperature through the use of special catalysts.  For the urea-
furfural alcohol binders, setting is possible at room temperature or
higher depending on the type of catalyst used.  With the successful use
of the newer core binders that do not require high temperatures for
setting, it appears that fewer and fewer foundries will continue the
practice of core baking.

          In addition to special binders, certain other materials are
frequently used in preparing core sands.  These include:  iron oxide,
ground corn flour;  water soluble compounds of wood sugar; coke pitch;
and ground hardwood cellulose.   Those materials facilitate removal ol"
cores.

          Once the cores are formed and cured, they are integrated with the
final molds which are then transferred to the metal pouring area.  Molten
metal of the desired composition is prepared in one of several different
types of commonly used furnaces.  Charge materials for the cupola furnace
usually consist of a flux material, coke, and metallics.  Electric arc or
induction furnaces do not require coke.  Typical fluxes include  limestone
(CaCO,), fluorspar (mostly CaF,), and soda ash (Na C)_).  The metallic
charge consists mainly of external scrap and some internally generated
scrap.  For producing gray and ductile iron castings, cupolas and electric
induction furnaces are the most widely used, with cupolas accounting for
an estimated 60 to 65 percent of total production.  Reverberatory furnaces
account for one percent or less of gray and ductile iron castings.  Most
malleable iron castings are produced in cupolas and electric induction
furnaces, although a number of air furnaces are still in operation.  Electric
arc furnaces account for almost all of the steel castings produced with
electric induction furnaces accounting for probably less than 5  percent.

          The molten metal is tapped from the furnaces into ladles and
poured into the waiting molds.  After the castings have solidified they
are separated from the molds in the shakeout area.  The separated castings
arc then cooled prior to cleaning and finishing.  Cleaning and finishing
operations include shot blasting, chipping and grinding.

          Following casting shakeout, the mold and core sands are screened.
Larger remnants of undisintegrated cores (core butts) and larger chunks of
molding sand are transferred to a disposal area.  Most of the molding sand,
along with the degraded core sand, proceed directly back to molding sand
preparation without going through sand reclamation (i.e., this sand is
recycled, rather than being reclaimed).  In some foundries a portion of
this return sand is bypassed through a reclamation system and then returned
i.o either Lhu core or molding sand mixing operation.  In the case of no-bake
sands, most of the sand from the shakeout may be returned through the sand
reclamation unit before recoating.  Excess sand is sent to landfill.

2.2.2     Description of Waste Streams

          The major types of solid wastes generated at iron and  steel
foundries were indicated in Figure 2.  The general types of waste generated
are essentially independent of the type of metal being cast and  the type
of furnace in use.   On the other hand, metal type and furnace type can
affect the quantities of waste produced.  The numbers in parentheses in
Figure 2 indicate the amounts of waste in each category expressed as kilo-
grams of waste per ton of metal melted.  The numbers correspond  to an
average plant producing iron in a cupola.  The values are given  on the
basis of a ton of metal me1 tod rather than on the basis of a ton of finished
castings, because yield factors (weight of finished casting/weight of metal
melted) vary depending <>;i the- foundry and tho type of metal cast.  For
iron (gray,  ductile and malleable) the yield factor is generally in the
r.ui^f of ().() to 0.7,  while for .steel values of 0.5 are common.   For the
purpose of computing total waste quantities for an average iron  foundry,
                                     75

-------
a yield factor of 0.65 would be reasonable.  Thus, a typical iron founo.--/
woul.i molt about 11,000/0.65 - 16,900 tons of metal per year (15,300
iT.etiic tons/year).

.Hi!1" ^'L''J    As stated previously and shown in Figure 2 there are two
types of waste sand.  One type is the clay bonded molding sand used in
interior parts of the mold.  Combined product!-*" of the two types of
wute sand is 330 kg/MT of cast product.  AJthough these sands have
>KxTerent organic additives as described on ,-^e ?2 the organic fractions
are burned and charred during the pouring of molten metal leaving principally
sand coated with carbon residues and traces of metal compounds including
copper, lead, chromium and zinc.  Solubility tests on spent foundry sand
us described in Appendix B did not show significant leaching of heavy
metals or phi-no 1.  For this reason foundry sands are not considered
potentially hazardous at this time.

Core Butts.    After the metal pouring process most of the sand is devoid
of binder and has little aggregation.  Quite often portions of the core
sand retain its binder.  It is removed as large chunks known as core
butts and brought to dumping areas.  Core butts are generated at a rate
oi" 48.1 kg/MT of casted metal.  Although solubility testing on core
butts was not conducted it is not expected to leach to a greater extent
than spent sand.  Core butts are therefore not considered potentially
hazardous at this time.

Dust.   Dust is generated at a rate of 31.7 kg/MT of foundry product
from the sand reclamation process and from baghouuses on metal milling
furnaces.  Dust will principally be silica oxides and iron oxides with
traces of heavy metals including lead, cadmium, copper chromium, nickel,
and zinc.  Solubility tests on foundry dust as described in Appendix B
did not show significant leaching of potentially hazardous metals.  For
this reason foundry dust is not considered potentially hazardous at this
time.

Sludges.   Wet scrubbers used to scrub emissions from metal pouring
operations produces a wastewater which in turn produces a sludge at a
rate of 18.2 kg/MT cast metal product.  This sludge will contain iron
for the most part along with traces of cadmium, copper, chromium, nickel,
lead and zinc.  Solubility tests were not conducted on sludges.  They
would be expected to be of similar composition and nature as furnace
dusts however which were studied in solubility tests as described in
Appendix B.   Since the dusts did not leach significant concentrations of
toxic constituents sludge was assumed to be of a similar solubility and
therefore is considered as not potentially hazardous at this time.

Slag.   Slag from iron and scrap steel furnace smelting is produced at a
rate of 56.3 kg/MT of finished iron and steel casting.  The gravel size
to sand size pieces of slag contains iron, lime and soda ash principally,
with small traces of heavy metals including cadmium, copper, chromium,
nickel, lead and zinc.  Solubility tests as described in Appendix B did
not show significant leaching of potentially toxic constituents.  For
this reason furnace slag from iron and steel foundries is not considered
hazardous at this time.

-------
I Jonrswei'piii^r..    Cleanup of floor;, in core making r\,oms results in
•liuuly floor sweepings ;it a rate of  11.8 kg/MT of product.  This is
assumed similar to other waste sands and therefore non-hazardous at this
time.  Solubility tests were not conducted on floor sweepings.

Refract or ios.   Broken and weathered brick refractories from metal
melting furnaces are generated at a rate of 10 kg/MT of finished castings.
These bricks are predominantly highly insoluble fired clay ceramic and
are not considered potentially hazardous.

          Appendix A gives analyses of iron and steel foundry wastes
including sands, dust and slag.

2.2.3     Waste Quantities

          Table 12 gives generation factors for the various residuals
from iron and steel foundry production as well as concentration factors
for potentially hazardous constituents.  The waste' residual factors
given in Table 12 are estimated average values for all foundries in each
of the three major foundry categories.  In developing the waste factors,
consideration was given to the different types of furnaces used in each
metal category and to tho different typos of furnace omission control
systems,  For example, gray and ductile iron is made in cupola furnaces
and electric induction furnaces in the ratio of about 3 to 2.  Control
for cupola furnace emissions is devided about equally between wet and
dry systems, while electric induction furnaces generally require no
emission control.

          In generating the overall waste factors, the computation of
sludges, and dusts and slag accounted for the percentage of castings
within a given category made from a specific type of furnace with a
specific type of control by weighing the waste factors for specific
combinations according to the frequency of their occurrence.

          Table 13 presents the amounts of wastes and the amounts of
specific potentially hazardous constituents generated annually for an
average plant in each of the three major foundry categories.  The amounts
shown were calculated using the waste factors given in Table 12 and
taking the following average annual production figures for finished
castings for each type of foundry:  (a) gray and ductile iron foundries -
10,000 metric tons, (b) malleable iron foundries - 12,700 metric tons;
and (c)  steel foundries - 5,400 metric tons.

          The quantity of waste generated by ferroalloy plants on a state-
by-stiite basis arc given in Table 14 for 1974, 1977, and 1983.  The quantities
of sludges and dusts arc based directly on information derived from a solid
waste survey sponsored by the Ferroalloy Association in which the quantities
of wastes from furnace emission control were tabulated for each state for each
type of ferroalloy.  The sludges result from the collection of furnace
emissions using wet scrubbing systems.  The dusts represent the furnace
                                     77

emissions collected by dry control systems.  The amounts of individual
constituents were calculated by multiplying the total waste figures by
the concentration values derived from laboratory analyses of waste
samples collected at several plants.

          An alternative approach for comniling sludge and dusts values
for each state might be to multiply tuc, waste generation factors given
in Table 12 by the production figures on a state-by-state basis.  This
approach was not used since state production figures were not directly
available for each type of ferroalloy and the numbers of plants using
each type (wet/dry) of control system was not known.

          The waste slag quantities were calculated by multiplying the
slag generation factors obtained from plant visits  (see Table 12) by the
state production figures for each type of ferroalloy as estimated from
the sludge and dust values obtained from in the ferroalloy survey and
from furnace- emission data contained in Reference 7.  The sums of the
sludge and dust values were divided by the furnace emission factors for
each ferroalloy category for each state to obtain production estimates.
The state production estimates for each ferroalloy were then summed and
compared with published national figures.  The individual state figures
were then adjusted as appropriate so that the national figures agreed.
The slag constituent values for each state were obtained by multiplying
the total slag values for each alloy type by the concentration values
determined through the analyses of collected slag samples, and summing
over all alloys.

2.3       TREATMENT AND DISPOSAL TECHNOLOGY

2-3-1     Current Treatment and Disposal Practices

Slag.   Slag which originates from the metal smelting furnaces is open
dumped.  This practice is considered environmentally adequate at this
time in the absence of significant leaching of toxic constituents as
ascertained in solubility tests as described in Appendix B.

Waste Sand.    Waste sand from cores and molds may either be reclaimed
for making new molds or disposed of in open dumps.  Open dumping is
considered environmentally acceptable at this time in the absence of
significant leaching of toxic constituents as ascertained in solubility
tests described in Appendix B.

Coro Butts.    Ciorv butts containing non-degraded sands ami binders are
also open dumped.   Although solubility tests were not conducted on core
butts they are not considered potentially hazardous at this time.
Solubility testing on core butts is needed to confirm non-leachability.
                                     95

-------
Sludges.   Sludges originating from wet scrubbing of furnace emissions
is generally mixed with dry sands, dusts or other dry wastes and open
dumped along with these wastes.  This practice is considered environ-
mentally adequate at this time in the absence of significant leaching of
toxic constituents as ascertained in solubility tests described in
Appendix B.

Dusts.   Dusts originating from sand reclaiming or control of emissions
from furnaces are open dumped.  This practice is considerad environmentally
acceptable at this time in the absence of significant leaching of toxic
constituents as ascertained in solubility tests described in Appendix B.

Refractories.   The broken, or eroded brick refractories from furnaces
are open dumped and are considered non-hazardous.  Open dumping is
considered environmentally acceptable.

Floor Sweepings.   Sweepings from the core making room are principally
sand and are not considered potentially hazardous at this time.  Solu-
bility tests were not conducted on sweepings but are needed to confirm
designation as non-hazardous.

          Since all of the wastes from iron and steel foundries are
considered non-hazardous at this time Levels I, II and III technology

2.4       COST ANALYSIS

          Because none of the iron and steel foundry wastes have been
considered potentially hazardous based on available evidence at this
time there are no costs attributable to hazardous waste disposal.

 3.0       PRIMARY SMELTING AND REFINING OF FERROALLOYS  (SIC 3313)

 3.1       INDUSTRY CHARACTERIZATION

          Ferroalloy is the generic term for alloys consisting of iron
 and one or more other metals.  Ferroalloys are used in  steel production
 as alloying elements and deoxidants.

          The major types of ferroalloys produced are ferromanganese,
 silicon manganese, ferrosilicon, ferrochrome and silvery iron.  The 1972
 production of the ferroalloys and percent of total ferroalloy production
 for that year are as follows:  (Reference 6)

          Ferromanganese           726,416 MT           32%
          Silicomanganese          139,014              6%
          Ferrosilicon             767,505              33%
          Ferrochrome              319,611              14%
          Silvery Iron             147,940              61,
          Other                    206,294              9%

          Total U.S. ferroalloy production in 1971 and  1972 was 2,114,733
 and 2,292,153 MT respectively.  Production of the above alloys comprises
 over 90% of the industry.  Ferroalloys produced in minor quantities
 (approximately 9% of total) are ferronickel, ferrophosphorus, ferrotitanium,
 ferrocolumbian, ferrotungsten and ferromolybdenum.

          U.S. producers of ferroalloys are listed in Table 15.  Table
 16 gives ferroalloy plants by process by state, EPA region and nationally.
 There is insufficient information available to estimate state by state
 and regional production capacities.  Total value of U.S. ferroalloy
 shipments in 1973 was $720,542,000 (Ref. 8).

 3.2       WASTE CHARACTERIZATION

          This section contains descriptions of production technology at
 ferroalloy plants and the resultant byproducts or wastes which are
 either recycled directly or disposed of on land.  Estimates are given
 for the quantities of wastes and potentially hazardous constituents
 thereof which are disposed of on land either in lagoons or open dumps.

 3.2.1     Process Descriptions

          Because of the common coproduction of ferromanganese and
 silicoman^anese within the same plants and close similarities in pro-
duction technology these ferroalloys will be treated together.  Production
of ferrosilicon,  ferrochrome, and ferronickel will be dealth with separately.

          Ferromanganese and Silicomanganese.   The assumed plant has a
daily capacity of 236 metric tons (260 short tons) of ferromanganese and
74 metric tons (82 short tons) of Silicomanganese.  Ferromanganese is
produced in two furnaces.   The Silicomanganese is produced in a single

                                   97

furnace.  Annual production is given as 81,100 metric tons (89,400 short
tons] of ferromanganese and 25,400 metric tons (28,000 short tons) of
silicomanganese on the hasis of an 11.3 month operating year for each of
the three furnaces.

          Raw materials for the production of standard ferromanganese (80%
Mn and 6.5% C, with the balance mostly iron) consist of manganese ore, coke,
mill scale and melted ferromanganese.  The input materials are sized,
mixed together and introduced into the furnaces directly over the molten
bath.  An overall flow sheet is shown in Figure 3.  The furnaces are of
the open submerged-arc type having three vertical Soderberg-type electrodes
arranged in a triangle.  The ends of the electrodes protrude 5 to 6 feet
below the molten bath material.  A paste, consisting of coke and pitch,
is fed into the electrode shells from the top.  As the paste descends,
it is baked into a solid mass by the heat of the furnace.

          The molten ferromanganese collects at the bottom of the furnace
and is tapped into ladles for transfer to a cooling area.  Slag is decanted
from the top of the ladles, and the product is poured into a cooling bed
in layers, a process called layer casting.  The solidified product is broken
into pieces and sized for sale.  The ferromanganese slag is rich in manganese
and most of it is used as charge material for silicomanganese production.

          The silicomanganese is also made in an open submerged-arc furnace
whose general operation is similar to that of the ferromanganese furnaces.
The process flow diagram is shown in Figure 3.  Input materials for silico-
manganese production consist of coal, coke, manganese ore, ferromanganese
slag, quartz, mill scale, dolomite, and remelt.  The molten silicomanganese
is tapped from the furnace into ladles, and the slag is decanted off.  The
product is cast into layers prior to final sizing.  The slag cannot be
recycled within the plant so most of it is sold to contractors for use as
road fill.  Some is sent to an on-s i to. disposaj .'irea.

          The air emissions for all three furnaces are controlled by wet
scrubber systems.  The emissions scrubwater from the ferromanganese furnaces
with solids amounting to 150.6 kg/MT of product is lime treated and-clarified.

          Ferrosilicon.   There are three major types of ferrosilicon
produced in the United States:  75% FeSi, 50% FeSi, and 16-22% FeSi, where
the percentages indicate the amount of silicon in the product.  The 16-22%
FeSi type is commonly called silvery pig iron and accounts for about 20
percent of the total ferrosilicon production.

          Most of the ferrosilicon produced in the United States is made in
electric submerged-arc furnaces.  An average furnace size might be about
15 megawatts with a daily capacity of 37 MT (41 tons) to 65 MT (72 tons),
depending on whether the furnace produces 75% FeSi or 50% FeSi.  The energy
required for 75% FeSi production is about 75% greater than that required for
50% FeSi production.  Specifically, the production of 75% FeSi requires
only 5.5 mw-hr per MT.  Input materials for ferrosilicon production consist
of quartzite, scrap steel, coal, and coke.

          I• er-rochrome Product urn.    Ferroehrome is made in two grades, high
carbon (HCj  and low carbon (LC).   Most of the ferrochrome produced in the
United States is of the high carbon type,  Input mate-rials consist of chromium
ore, quartzitc, limestone, coal and coke.  The electrical energy required
to produce (HC) ferrochrome averages about 4.6 megawatt-hours per metric ton
of product.   Furnace emissions average 168 kg of particulates per metric
ton of product  (335 Ib/ton) for either high or low carbon ferrochrome.  An
average ferrochrome furnace might be rated at 20 megawatts.  Thus, the
average furnace would produce about 104 metric tons (115 short tons) of
ferrochrome  per day.

          Fc-rronickel.    There is only one ferronickel producing plant in
the United States located at Riddle, Oregon.  Nickel ore is mined at the
top of a mountain and transported to the plant by tram cars.

          The plant operates around-the-clock producing approximately 23,600
metric tons  (26,000 short tons) of ferronickel (50% Fe, 50% Ni) annually.
Reduction of the nickel ore is accomplished by mixing the melted nickel ore
with ferrosilicon (48% silicon).   The required ferrosilicon is produced in
the same plant at the rate of about 20,620 metric tons (22,730 short tons)
per year.

          The sequence of operations for producing ferronickel consists of
ore mining and preparation, melting, reduction, and refining.  A flow
diagram is presented in Figure 4.   The mined ore is first dried and then
screened into three fractions.  The coarser, low grade rock is diverted to
a reject ore pile for possible use in the future if an economical process
for nickel extraction can be developed.  The ore fraction in the 5/16" to
3/4" range is crushed and temporarily stored.  The-5/16" fraction is
further screened to remove the fines which are stored separately.  The
coar.scr retained ore fractions arc calcined and the fines are roasted.
The coarse and  fine fractions arc- then transferred to hot ore bin.s from
which they are gravity fed to the furnaces.  Ore melting i^ curried out in
four JO,000  KVA electric furiures.  The molten nickel ore  i - rapped into
ladles and vigorously mixed with ferrosilicon which acts as the reducing
agent.  Mixing is accomplished by transferring the molten mixture back and
forth between two ladles.  During the reduction process, a fraction of the
ferronickel  is removed from the ladle at regular intervals and introduced
into two small electric furnaces for refining.  Other input materials for
the refining operations are limestone, dolomite, fluorspar, iron ore, and
coarse concentrates from the skull plant.

          The skull plant processes slag from the refining furnaces, metal
spills and residues from the ladles (called skulls) to produce concentrates
of high metal content that are recycled to the refining furnaces and to the
ferrosilicon furnace.  A hammer mill pulverizes the input materials and
the coarser  metal-rich fraction is removed magnetically.  The finer tailings
are slurried with water and piped to a tailings pilo.

          l;errosiI icon is produced in a 15,000 KVA electric furnace with
input maUn-iuls consisting of quarrz, iron turnings, coke, wood chips, and
•.kul I plant  concentrates.  All t'orrosilicon produced is cast, crushed and
used for reduction of tho nickel ore.

          The molten slag generated during the reduction of the nickel ore
is granulated by high pressure water sprays and transferred to the slag
pile by conveyor belt.  The fines derived from granulation of the slag are
carried in the water stream to settling ponds (or lagoons).

3.2.2     Description of Waste Streams

l-erromanganese and Silicomanganese

          Slags.   A dense vesicular slag is generated from ferromanganese
production at a rate of 600 kg/NTT ferromanganese product.  Approximately
360 kg/MT of the 600 kg/MT generated is used as an input to the silica-
manganese furnace.  The remaining 240 kg/NTT is stored on the ground for
possible future use in Silicomanganese production.

          In the production of Silicomanganese a glassy textured slag is
generated at a rate of 1100 kg/MT of Silicomanganese product.  Of this
amount approximately 785 kg/MT product is sold for road base with 315 kg/MT
product disposed of in open dumps.

          Major constituents of ferromanganese and Silicomanganese slag
are manganese, manganese oxide, silica, alumina, calcium oxide and magnesium
oxide.  Trace metals in these slags include chromium, copper, lead and zinc.

          In solubility tests described in Appendix B there was no leaching
of toxic heavy metals at greater than 0.2 ppm from either  ferromanganese or
iiiiv.oi.:aiiganese slag.  For this reason in addition to the  dense nature of
the  - la;; ,,ferromanganese and Silicomanganese slags are not considered hazardous
at this time.

          Dusts and Sludges.   Depending on whether wet or dry emissions
controls are used on furnaces, dusts or sludges are produced.  Figure 3
illustrates emissions control residuals using wet scrubbers.  Emissions
from the ferromanganese furnaces are generated at a rate of 167.4 kg/MT
of product.   Ninety percent of these emissions or ISO.6 kg/MT product are
captured in wet scrubbing systems.  The scrubber water is  lime treated and
clarified.   Underflow sludge from the clarifier is generated at a dry
weight rate of 164.8 kg/MT product and settled in a lagoon.

          Emissions from the silico-manganese furnace are  generated at a
rate of 109 kg/MT Silicomanganese product.  Ninety percent of the emissions
are captured in wet scrubbers as shown in Figure 3 and sent to a settling
basin at a rate of 98.5 kg/MT product.  Solids are collected in the settling
basin, dredged several times per week and trucked to an on-site open dump
at a rate of 7-1 kg/MT product.
                                     104

-------
          Overflow from the settling basin carries 23 kg of dry solids /MT
product to the lagoon.  Solids from the lagoon are periodically dredged and
open ilumpud -it w rate of  1K7.H kg/MT of product.

          In solubility tests described in Appendix B, dusts and sludges
from silicomanganese emissions control leached lead at approximately  1.3 ppm.
Ferromanganese dusts leached 110 ppm zinc and 560 ppm lead.  For these reasons,
along with the fine particulate nature of these wastes, sludges and dust,
residuals from ferromanganese and silicomanganese production are considered
potentially hazardous at  this time.

Ferrosilicon

          Dust.   The production of ferrosilicon generates no slag.   Therefore,
control of furnace emissions produces the only significant solid waste.  While
dry-and-wet emissions control systems are utilized, dry type systems  are more
prevalent.  Furnace emissions average about 450 kg/NTT (900 Ib/ton) for
75"s FeSi and 225 kg/MT (450 Ib/ton) for 50% FeSi. Thus, for furnaces  controlled
by bughouse collection systems the average quantity of collected dry  dust will
vary between 405 kg/MT product and 202.5 kg/MT product depending on the type
of FeSi being made.  An overall hooding and capture efficiency of 90  percent
is assumed.  The collected dusts are trucked to a land disposal area  for
open dumping.

          In solubility tests described in Appendix B there was no leaching
of toxic heavy metals greater than 0.3 ppm from ferrosilicon baghouse dust.
Sludge would be expected  to behave similarly.  For this reason dusts  and
sludges from ferrosilicon production are not considered potentially hazardous
at this time.

Ferrochrome

          Slag.   In ferrochrome production the slag-to-product ratio is
estimated to vary from 1.5 to 2.0.  Therefore the slag generation factor is
approximately 1750 kg/MT of ferrochrome product.  The slag occurs in  dense 4
to 6 inch diameter clumps and has a vesicular surface.  The slag is either
open dumped or processed to produce two or more fractions and sold for use
in road building.

          In solubility tests described in Appendix B, there was insignificant
leaching of toxic constituents from ferrochrome slag.  This slag is therefore
not considered potentially hazardous at this time.
                  Available data show that both wet and dry emissions controls
systems are used in ferrochrome production.  If the furnace emissions are
controlled by a dry system 151 kg of dust per MT of ferrochrome product will
be collected on the assumption that the overall hooding and collection
efficiency is 90%.  The collected dust is usually trucked to an on-site
dump for final disposal.
                                     105

-------
          In solubility tests described in Appendix B it was found that
dusts from ferrochrome production leached over 100 ppm chrome and around
1 ppm lead.  For this reason dust from ferrochrome emissions control is
considered potentially hazardous at this time.
                    For a wet collection system operating at an overall
capture efficiency of 90*, the same weight of particulates would be contained
in the scrubber water as were captured by the dry system.  The scrubber water
would be piped to a settling basin to allow the particulates to settle.  An
estimated 97% or 146.5 kg/MT product of the solids would be retained in the
settling basin.  Accumulated bottom sediments in the settling basin would be
pumped out or clammed out periodically and dumped on adjacent land areas.

          As discussed previously ferrochrome dust released chrome and lead
In solubility tests.  Sludge would be expected to behave similarly and is
therefore considered potentially hazardous at this time.

Ferronickel

          Slag.   Granulated slag from the reduction operation is generated
at a rate of 31 MT/MT production, a very high ratio of waste to product.
Accumulation of this sla& since the plant began operation in H)54 has produced
a huge slag pile covering many acres and extending up to a height of 100 feet
or greater.  A very small fraction of the slag is purchased by a local con-
tractor for road base.

          So.Uds are carried from the slag granulation operation into a large
lagoon (approximately 12 acres) at a rate of 697 kg/MT ferronickel product
(see Figure 4 ) .  Sludge amounting to 576 kg/MT product is dredged once a year
from the lagoon and open dumped on land adjacent to the lagoon.  Overflow
from the settling lagoon is diverted to a second lagoon which is not dredged.

          In solubility tests described in Appendix B zinc leached from slag
at 2.0 ppm and lead at 1.0 ppm.  The fines from this slag (i.e. sludge) how-
ever, did not leach toxic heavy metal constituents beyond 0.3 ppm in the
solubility tests.  For this reason slag and slag fines (sludge) are not con-
sidered hazardous at this time.

          Skul 1 V t ant Tai ] ing s .   Tailings from the skull plant as shown in
Figure 4 are generated at the high rate of 5.3 MT/MT product.  The tailings
are piped to the tailings pile at the rate of 360 MT (400 short tons) per day.
Water runoff from the tailings pile is diverted to the lagoon which receives
slag granulation water.  Since the skull plant began operation the skull
plant tailings pile has grown to an impressive area and height but is dwarfed
by the mountainous slag pile.

          In solubility tests described in Appendix B, skull plant tailings
leached copper and zinc at approximately 50 ppm.  For this reason skull plant
tailings are considered potentially hazardous at this time.
                                     106

-------
          busts.   Dusts collected during ore preparation including drying,
crushing, calcining and roasting are fed to the furnaces so no significant
solid waste accumulates from control of emissions from these operations.

          Dusts from the electric turnace are captured in baghouses and
recycled to the furnaces with the exception of dust collected from the
ferrosilicon furnace.  The ferrosili.on dusts are collected at the rate
of 84 kg/MT product, wetted to preven; blowing, and disposed of in the
slag pile.

          In solubility tests described in Appendix B ferrosilicon furnace
dust did not leach any toxic heavy metals greater than 0.3 ppm and is
therefore considered non- hazardous.

3.2.3     Waste Quantities

          A number of ferroalloy plants were visited and samples of waste
residuals obtained for subsequent chemical analyses.  These analyses are
given in Appendix A.  From these analyses and data provided by individual
plants on quantities of wastes, waste generation and constituent concentra-
tion factors were developed.  These factors are given in Table 17.  Using the
generation and concentration factors in Table 17 the yearly generation of
waste residuals from typical plants have been estimated.  These estimates
are given in Table 18 for typical plants producing the various ferroalloys
(FeMn, SiMn, FeSi, FeCr, FeNi).  Based on plant capacities, data supplied
by individual plants, and chemical analyses of collected samples, estimates
of the total quantities of land disposed wastes and potentially hazardous
constituents thereof have been made on state by state, EPA regional, and
national levels.  This data is tabulated in Table 19 for 1974, 1977 and
1983.  Estimates for growth, in ferroalloy capacity by 1983 is approximately
4%.  Inherent error in estimated waste quantities does not warrant meaningful
increased 1977 and 1983 projections at this growth rate.

          Oregon with only two ferroalloy plants generates the greatest
amount of slag and sludge than other states with ferroalloy industries.  This
is a result of the ferronickel plant which generates very large quantities of
waste per unit of product.  Ohio which has 8 ferroalloy plants generates the
second largest quantity of slag and sludge and the greatest quantity of dusts.

3.3       TREATMENT AND DISPOSAL TECHNOLOGY

3.3.1     Current Treatment and Disposal Practices

Ferromanganese and Silicomanganese

          Slag.   Slag from the ferromanganese furnace which is not used
as charge material in Silicomanganese production (approximately 40% of total
slag) is stored on land for possible future use.  Approximately 30% of
residual slag from Silicomanganese furnaces which is not able to be sold as
road fill is open dumped.   Open dumping or salo as roadfill are environmentally
.HlcquaJc sinro forromariKanose and silicomangaru'se slags are not considered
potentially hazardous at this Lime.

          Sludges and Dusts.   At the present time lime treated scrub-
water from ferromanganese furnace emissions control and wet scrubber
sludge from silicomanganese emissions control is settled in lagoons or
settling basins.  Settled sediments are periodically dredged and dumped
on land.  Dusts are either directly dumped on land or wetted before
dumping to prevent blowing.  The present methods of disposing of sludges
or dusts are considered inadequate because of the danger of leaching of
lead and zinc.

Ferrosilicon

          Dusts and Sludges.   Collected dust from ferrosilicon furnaces
is usually trucked to on-site open dump areas.  Dust is wetted down to
prevent blowing from the truck while being transported.  If wet emissions
control is used a sludge is generated ^hich is open dumped.  Open dumping
of dust or sludge is environmentally acceptable since they are not con-
sidered hazardous at this time.

Ferrochrome

          Slag.   Electric furnace slag is open dumped or sold for use
in road building.  These practices are environmentally adequate since
solubility tests indicated that ferrochrome furnace slag is non-hazardous
at this time.

          Dusts and Sludge.   Either dusts or scrubber water is generated
from emissions control on ferrochrome electric furnaces depending on the
method of air pollution control practiced.  Dusts are open dumped while
scrubber waters are put in unlined lagoons with periodic dredging of
settled sediments.  Dredged sediments are open dumped.  Current practices
of dust and sludge disposal are considered inadequate because of the
possibility of chrome and lead leaching.

Ferronickel
          Slag.   Granulated slags from reduction furnaces are presently
open dumped.  This practice is adequate since ferronickel slag is not
considered hazardous at this time.

          Skull Plant Tailings.   Skull plant tailings are currently open
dumped.  This practice is not considered adequate because of evidence of
zinc and copper leaching at approximately 50 ppm in solubility tests.

          Sludges.   Sludges result from settling of slag granulation
water and skull plant tailing water in an unlined lagoon.  The sludges
are dredged from the lagoon and open dumped.  The sludge from slag granu-
lation is not considered potentially hazardous while that from skull plant
tailings is considered potentially hazardous.  Since they accumulate in the
same lagoon, the entire sludge volume must be considered hazardous at this
time and the use of an unlined lagoon as not acceptable.
                                     113

-------
          Dust .    The only land disposed dust from ferronickel production is
the emission control dust from the associated ferrosilicon furnace.  This
dust is open dumped on land, an environmentally acceptable practice since
ferrosilicon dust is not considered potentially hazardous at this time.

          Levels of treatment and disposal technology for those ferroalloy
wastes which are considered potentially hazardous are discussed in the
following sections.

3.3.J     Present Treatment and Disposal Technology (Level I)

Ferroinanganese and Silicomanganese

          Sludges and Dust.   Lime treated scrubwater from ferromanganese
furnace emissions controls and wet scrubber sludge from silicomanganese
emissions control is settled in lagoons or settling basins.  Settled
sediments are dredged and open dumped.  Dusts are either open dumped directly
or wetted before open dumping.  These practices are inadequate because of
the possibility of heavy metal leaching and subsequent percolation through
permeable soils to groundwater.

settled in un lined lagoons with periodic dredging of settled sediments.
Dredged sediments are open dumped.  These practices are  inadequate because

          SKul. j^ I'Jant Tailings.   Skull plant tailings are presently  open
dumped.  This is not adequate since solubility tests indicate  leaching  of
zinc and copper which could percolate through permeable soils  to groundwater.

          Sludges.   Sludges from skull plant tailings water accumulates
in a lagoon along with sludge from slag granulation water.  Sludge  is
periodically dredged and open dumped.  The lagoon is unlined.  The  use  of
an unlined lagoon and open dumping of dredged sludge are considered in-
adequate because of the danger of heavy metal leaching through permeable
soils to groundwater.

3.3.4     Technology To Provide Adequate Health And Environmental
          Protection (Level III)

Ferromanganese and Silicomanganese

          Sludges and Dust.   The use of lined lagoons would be required for
settling of sludges.  Dredged sludges would need chemical fixation before
dumping on land to prevent heavy metal leaching.  Ground upon which dusts are
disposed would require soil sealing to prevent percolation of potentially
hazardous constituents.

Ferronickel

          Skull Plant Tailings.   The ground area for disposal of skull
plant tailings would require sealing with bentonite or other sealant to
prevent percolation of leachate.  Runoff water would be collected and
diverted to the lagoon.

          Sludges.   The lagoon receiving sludge from the skull plant
tailings pile and slag granulation would require a lining.  Dredged lagoon
sediments would be dried and disposed of in sealed soil areas.

          Tables 20a through 20e summarize features of Levels I, II and III
treatment and disposal technology for those wastes from the ferroalloy
industry which are considered potentially hazardous at this time.

3.4       COST ANALYSIS

          In the last section, various treatment and disposal technologies
currently employed or considered for adequate health and environment pro-
tection were described.  The costs for implementing this technology for
typical plants is considered in this section.  Costs are given separately
for plants producing ferromanganese and silicomanganese, ferrosilicon,
ferrochrome,  and ferronickel.

3.4.1     Cost of Present Treatment and Disposal  Technology (Level  T)

          Ferromanganese and Silicomanganese.    The typical plant produces
81,000 MT of ferromanganese and 25,400 MT of Silicomanganese operating
about 345 days/year.

          Effluents from both operations go to a lagoon.   It has a
volume of 10,700 m  and allows for 4 days of residence.   Its design
characteristics are:

          Volume              10,700 m3
          Bottom width            38 m
          Top width               50 m
          Bottom length           75 m
          Top length              87 m
          Total depth              3 m
          Depth of excavation   1.15 m
          Circumference          286 m.
          Dike volume          3,546 nu
          Dike surface         3,921 m
          Total width             63 m
          Total length           101 m
          Required area          .65 ha

          The daily inflow into the lagoon contains 40.6 MT of solids which
form about 29 m  of sludge.  This requires that the lagoon is dredged about
1.9 times/yr assuming that it is dredged when half filled with sludge.
This requires about 380 hours of dragline time based on a capacity of 27 m /yr
of frontloader and truck time.  The lagoon is located on semi-industrial
land.

          Scrubber water from the Silicomanganese furnace flows through a
concrete-lined settling pit before entering the lagoon.   The pit is sized
to allow a settling time of 30 minutes.  About ^K.7 Nfl of .solids are
removed weekly from the pit and trucked to the on-site dump.  This operation
is estimated to require 80 hours of truck and backhoe time/yr.

          Capital and annual costs of Level 1  treatment and disposal
technology are given in Table 21.

          Ferrochrome.   The selected plant produces 62,790 MT of ferro-
chrome/year operating 345 days.  Two types of wastes are generated.  One
is furnace slag (non-hazardous) which is open dumped or sold for use in
road building.  The other consists of wastes collected by air emission
control systems considered hazardous.  Both dry and wet systems are
employed for handling the latter waste, and costs are developed for both
systems.

          The dry system results in tha collection of 15.7 M7  >f dust/day
with a density of 500 Kg/m  .  The dust is transported to an op-site dump,
which requires 2 hrs/day of frontloader and truck time.

          In the wet system, the scrubber water is piped to a  lagoon.
The lagoon, like all other waste disposal facilities is assumed located
on semi-industrial land.  Inflow into the lagoon is at a rate  of 80 I/sec.
The lagoon size allows for 4 days detention.  Its characteristics are:

          Volume                        27,550 m3
          Bottom width                      63 m

          Total width                       90 m
          Total length                     153 m
          Required area                    1,4 ha

      ,   About 15.2 WT of solids settle in the lagoon daily which form
12.7 m  of sludge.  Dredging is required only once every three years.
On the average, 4,150 m  of sludge are dredged annually which  represents
220 hours of frontloader and truck time.

          The sludge dump is designed to accommodate lagoon sludge
dredged over a 20-year period.

          Capital and annual costs of Level I treatment and disposal
technology are given in Table 22.                                       .

          Ferrosilicon.   Since there are no hazardous wastes  believed
associated with ferrosilicon production at this time, there are no costs
associated with hazardous waste treatment and disposal.

          Ferronickel.   The model plant produces 23,600 NTT of ferronickel
operating 365 days/year.  Ferrosilicon required for the reduction of
nickel is produced in the same plant at a rate of about 20,620 MT/yr.
The only wastes associated with ferronickel production which is believed
hazardous is skull plant tailings and associated sludge.

          Tailings from the skull plant are piped to a tailings pile.
Solids accumulate at a rate of about 360 NTT/day.  The water from the
tailings slurry drains into a lagoon which also receives water and
solids from slag granulation.   The tailings have an estimated  density of
1,300 kg/m .  Thus, about 275 m  of solids form daily and 100,375 m
annually.  The accumulation over a 20-year period amounts to about
2,000,000 m .   This will require a 7 ha area given that the tailings are
built-up to a height of 30 m.

          Solids carried into the settling lagoons accumulate at an estimated
rate of 13,600 MT/yr.  The sludge formed has a wet density of 1,260 Kg/m'
and a dry density of 1,390 Kg/m .  Most of the solids settle in the first of
two lagoons (Lagoon A).  The overflow from Lagoon A goes to the second lagoon
^Lagoon B).  The characteristics ot i.he lagoons are:

          Lagoon A is dredged once per year at which time about 10,800 m
of sludge is removed.  This requires about 400 hours of dragline time.  The
sludge is then deposited on adjacent land.  The transport is estimated to
require 520 hours of frontloader and truck time annually.
                                                           3                3
          In a dry state, sludge removed amounts to 9,785 m /yr or 195,700 m
in 20 years.  This will require a 2 ha area if the built-up is to 10 m.

          All dust except those from the ferrosilicon furnace are recycled.
The latter are not considered hazardous and therefore have no hazardous
waste disposal costs attributed to their disposal.

          Altogether, about 680,000 m  of solids are deposited on land
each year.  This is estimated to require 6,800 hrs of bulldozer time yearly
for spreading, shaping and compacting.  Capital and annual costs of Level I
treatment and disposal technology are given in Table 23.

          Ferromanganese and Silicomanganese.   The lagoon is lined and the
accumulated sludge is removed hy pumping instead of dredging.  The sludge
is chemically fixed prior to being deposited at the slag dump.  The slurry
pump is operated about 720 hrs/yr, and 1,000 labor hours are assigned for its
operation.  The use of the slurry pump eliminates the use of the dragline.

          Capital and annual costs are given in Table 24.

          Forrochrome.   The lagoon is lined, and the sludge or slurried
dust  is removed by pumping instead of dredging.  The sludge is chemically
fixed prior to being deposited at the dump.  The dump surface is sealed and
colli-rtion ditches installed, together with a pump and piping.  The slurry
pump is operated about 300 hrs/yr and 450 hrs are assigned for its operation.
The use of the slurry pump eliminates use of the dragline.  Capital and annual
costs arc given in Table 25.

          l-'orronickcl.   Both lagoons are lined and the accumulated sludge
is removed from Lagoon A by pumping instead of dredging.  The slurry pump
used for this purpose is operated about 765 hrs/yr and 1,000 labor hours
are assigned for its operation.  The use of the slurry pump eliminates the
need for the dragline.

          The pumped sludge is deposited on a sealed .25 hectare area
adjacent to Lagoon A for drying.  The runoff is collected in ditches and
then flows by gravity into Lagoon B.  The dried sludge is then hauled to
dump where the ground has been sealed.

          The tailings from the skull plant are deposited on sealed ground
and collection ditches are constructed at the dump site.  The capital and
annual costs of Level III treatment and disposal technology are given in
Table 2(>.

          Tables 27 Through 29 summarize the capital and annual costs for
Levels I, 11 ;md III treatment and disposal technologies for hazardous
land disposed waste from the U.S. ferroalloys industry.  Costs arc given per
metric ton of dry and wet wastes  (i.e. sludges) and per metric ton of
product.   Cumulative total industry costs for each ferroalloy sector to
meet Levels I, II and 111 treatment and disposal technology are also given.
Costs for each type of waste and  total costs for each ferroalloy sector are
also expressed as percentages of  product selling prices.

          Estimated 1973 annualized industry costs for Levels I and II
treatment and disposal technology of potentially hazardous wastes from
ferromanganese and silicomanganese production are $250,000 or 0.2% of
estimated national sales value.   The industry cost of Level III treatment
and disposal technology  (adequate for environmental protection) is estimated
as $1,310,000 or 0.8% of estimated national sales value.

          Assuming that wet systems are used for emissions control for
ferrochrome production the industry annualized costs for Levels I and II
treatment and disposal technology are estimated as $110,000 or 0.07% of
estimated national sales.  The industry annual cost of Level III technology
using wet emissions controls is estimated as $560,000 or 0.36% of 1973                      4
national sales.

          The estimated annual cost for Level I and II treatment and
disposal technology for potentially hazardous waste from the one United
States ferronickel plant is $60,000 or 0.18% of estimated 1973 sales
value.  Estimated annual costs for Level III treatment and disposal tech-                   -
nology are $160,000 or 0.48% of estimated national sales.
