                                  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 lagoon 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 in 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
d'ewaters 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 (BOF) 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
mold sand and reclaims significant quantities of core sand for recycle.

          The presence of potentially hazardous constituents in slags,
sludges, 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
or dusts.  Process wastes have been categorized as 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 be needed.  Collected runoff would require treatment
before discharge or retention and evaporation in lagoons.

          Costs for present and environmentally adequate potentially
hazardous waste treatment and disposal are given for each smelting and
refining catego.ry.

                                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
USEPA 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 "potentially1hazardous."
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-
ditions.

                    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 suitable 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

1.1       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
sales 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
steel 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)
are 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
sulfate, anhydrous ammonia, ammonia liquor, and naphthalene, are produced
in addition to coke.  A very small portion of coke is also produced in
the beehive coke process.   A byproduct coke plant 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.

1.2       WASTE CHARACTERIZATION

          This section contains descriptions of production technology at
iron and steel plants and the resultant byproducts or wastes which are
either 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 night
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
shown, 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 a 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 and Byproduct Production.   Coke serves both as a fuel
and as a reducing agent in the making of iron. "To produce the required
coke, bituminous coal is heated to drive off the volatile 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 controlled amounts of air into the coking chambers.
The heat generated by burning of the combustible volatiles provides
energy for maintaining the distillation process.

-------
          In the byproduct process, no air, is admitted to the coking
chambers, the heat for distillation being provided by the combustion of
fuel gas in contact with the walls of the coke ovens.  The' volatiles
driven off during distillation are piped from the coke ovens and processed
for recovery of useful byproducts.  After coking is completed (16 to 24
hours), 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
added which combine with impurities to form slag.  Fluxes include lime-
stone, lime, dolomite, and fluorspar.  Lirae is often made onsite at the
steel plant by the calcination of limestone.  The dusts generated in the
required crushing, screening, and handling of the materials are generally
collected and recycled.

          Blast Furnace.   Almost all of the basic iron required for
steel making is produced in blast furnaces.  Input materials, consisting
of iron ore, sinter, coke, and fluxes (primarily limestone), are charged
into the top of the furnace.  Air preheated to 1400 to 2100 F (760 to
1150 C) is forced into the bottom of the furnace,  the coke reacts with
the oxygen in the air to produce carbon monoxide which, in turn, reduces
the ore to metallic iron which settles to the bottom.  The molten iron
is tapped off into transfer ladles known as submarine cars for transfer
to the steel making shop.  Slag is drawn off at the surface of the
molten metal.

          The hot gases leaving the top of the blast furnace have' fuel
value and are commonly used in the blast furnace stoves to preheat the
incoming air and for underfiring the coke ovens.  Prior to use, the
gases are cleaned by passing them first through a dust catcher to remove
the coarser particulates and then through a wet scrubber.  Electrostatic
precipitators are also used at some plants.  The water from the wet
scrubber system is generally piped to a clarifier where the particulates
settle to form a sludge or slurry which is subsequently'dewatered, often
by a vacuum filter system.  Thus, the wastes derived from blast furnace
operations generally consist of slag, flue dust and sludge. •

          Steel Making.   For making steel, three different furnace
types are in use:  the basic oxygen furnace (EOF], the electric furnace,
and the open hearth furnace.  As stated previously, open hearth furnaces
are gradually being phased out and being replaced by BOF's.  Electric
furnaces are particularly well suited for making high quality and alloy
steels because of better control on operating conditions such as tempera-
ture and oxygen input.

          The metal charge to the basic oxygen furnace consists of about
70 percent molten iron and 30 percent cold steel scrap.  The open hearth
generally operates with a metal charge of SO percent molten iron and 50
percent scrap, although it can also accept a metal charge of 100 percent
scrap.  The charge to electric furnaces is predominantly.cold scrap.
                                     12

-------
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 ten
steel plants visited during this program, seven plants had BOF 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,
this 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 eontinous 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 eontinous 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 coining 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 pits.

          Rolling.    The billets,  blooms,  and slabs formed in the roughing
mill or in the eontinous 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
                                     13

-------
to .rolling by automatic or hand scarfing, an operation in which oxygen, under
pressure is directed at the surface.  Grinding and chipping are also used
for removing surface defects.  Thus, scarfing scale and grinding and chipping
residues are additional wastes generated at the rolling mills.

          Hot rolling is often followed by cold-rolling and cold-forming
operations.  Prior to cold processing, the steel is pickled by passing it
through vats of hydrochloric or sulfuric acid solution to clean the surface.
Waste pickle liquor is sometimes disposed of directly on land and, therefore,
constitutes a waste of interest to this program.  Neutralisation of the waste
pickle liquor is sometimes accompanied by the formation of sludges which are
also land disposed.

          In cold rolling, sheet steel becomes hardened and usually requires
annealing (i.e. softening by heat treatment).  Coils .of sheet steel are
annealed by heating them in a controlled atmosphere.  After cooling, the
annealed steel is then generally passed through a temper mill which gives
it the desired hardness, flatness, and surface quality.  No wastes are
generated in the annealing and tempering operations.  .

          Coating and Plating.   Further processing of the sheet steel
might include coating the surface with nonferrous metal, paint, or other
coatings.  Two common coating operations, tin plating and galvanizing,
are included in the flow diagram of Figure 1.  One common method of tin
plating involves electrolytic deposition.  The steel is first washed and
scrubbed and then cleaned in a dilute acid solution.  It is then passed
through an electrolytic solution, washed, and rinsed.  The coated sheets
are then heated so the tin flows to form a surface coating of high luster.
Finally, the surface is water quenched, electrochemically treated, and
coated with oil.  In galvanizing, the sheet steel is cleaned, heated,
dipped in molten zinc, cooled, and chemically treated.  In galvanizing and
tin plating, sludges are generated containing residuals from the cleaning
lines and from neutralization of the acid rinse water.'

Capacity of Typical Plant

          For the typical plant an annual capacity of 2,500,000 metric
tons of molten steel was selected..  This value is slightly greater than
the average ingot steel production for 45 of the major steel making plants
in the United States,  Facilities at the typical plant consist of a sinter
plant, blast furnaces, basic oxygen furnaces, electric furnaces, coke ovens,
a continuous caster, primary  (or roughing) mills, other hot rolling mills
(hot strip, bar, etc.), cold mills, annealing and tempering mills, a tin
plating mill and a galvanizing mill.  Table 4 gives the annual production
figures for each major facility at the typical plant.  The figures are
generally internally consistent, but in any one plant the relative amounts
of products of different types will vary as will the amount of home scrap
produced.  In addition, intermediate products such as blooms, billets or
slabs might be purchased and/or sold in any given year, so that the
ratio of weight of finished products-to-weight of steel produced will vary,

 1.2.2     Description of Waste Streams

           This section describes the types of wastes associated with
 each of the steel making processes previously described.   Generation
 factors for each type of wastes are given as well'as an assessment of
 their potential environmental hazard.

 Coke and_ jyproduct Plants.    Wastes generated from coke and byproduct
 coke plants include waste ammonia liquor, ammonia still lime sludge'and
 decanter tank tar.  The relative amounts of these wastes will vary
 considerably from plant to plant depending on the specific design of the
 byproduct recovery plant.

           Waste ^Ammonia Liquor.   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.
 This 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 WT
 of coke for-1 ton of steel.  Waste ammonia liquor contains significant
 concentrations 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 generated at a rate of
 2.3 kg/MT steel along with ammonia still lime sludge is sent to open
 dumps.  In solubility tests described  in Appendix B decanter 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 includ'e slags,
• sludges and dusts.  The quantities and nature of 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, dusts from dry air emissions
 controls or sludge from wet air emissions controls.

                                      16

-------
          Slag.    Blast  furnace  slag  is generated at  a rate of  348 kg/OT
 of  iron -output  from  the  blast  furnace or 250-kg/WT -of finished -steel.
 It  is normally  granulated by quenching the molten slag with water.  This
 produces  sand size to  large chunks of a hard vesicular slag 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.

          Dust.    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/WT 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.

          Sludge.    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 (EOF).    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.

          Slag_.    A dense slag containing large amounts of silica, iron and
 lime, minor amounts of sulfur  and phosphorus and significant concentration's-
 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.

          Dust.    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/hfT 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

-------
 significantly.   For this reason BOF dust  is not  considered potentially
 hazardous at  this  time.

          Sludge.   Sludge  from wet control of air emissions from BOF's
 is also predominantly  iron  oxides, silica oxide  and  lime with small but
 significant concentrations  of the trace metals chrome, copper, manganese,
 nickel, lead 'and zinc.  It  is generated at a rate of 17.3 kg/MT of steel
 product (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.

          Slag.    A dense,  hard slag is generated at a rate of 243 kg/MT
 of steel 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.

 Electric Furnaces. *  Residuals from electric'furnaces include slag, dust
'and sludge.

          Slag.   A dense hard slag is generated at  a rate of 120 kg/Ml
 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.   Dust from dry emissions controls is generated at a
rate of 12.^8 kg/MT of steel.  It is principally iron and silica oxides
and lime with 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,

          Sludge.   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 line.  In
solubility tests described in Appendix B'electric furnace sludge leached
chromium (94 ppm) and lead (2.0 ppm) in significant concentrations.
Electric 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/Ml" steel
Cold Rolling Mill - 0.16 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

-------
Mill- Scales.  .Mill scales .containing-over 50% iron axe generated from
the following mills:

          Primary Mills  44.9 kg/MT steel
          Continuous Casting Mills '8.7 kg/MT steel
          Hot Rolling Mills  18.3 kg/MT steel
          Cold Rolling Mills  0.052 kg/MT steel

          Mill scales contain over 501 iron as 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.

Pickle Liquors.   Acid pickle liquors (HCli H.SO.) are used in cold
rolling mills and galvanizing mills to clean iron and steel metal surfaces.
Spent acid is generated at a rate of 22.8 kg/MT steel from cold rolling
mills and 5.17 kg/MT steel from galvanizing mills.  Waste pickle liquor
contains about 4-6% acidity and large concentrations of dissolved and'
suspended iron.  Chromium, copper, nickel, lead and zinc are also present
in minor concentration (less than 20 ppm).  The high acidity (pH less
than 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 all available data collected from the 10 iron and steel plants
visited on generation rates and chemical analyses data from collected
residuals samples of slags, 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

                       *Quantities calculated from generation and concentration
                        factors given in Table 5 based on  annual production figures
                        given in Table 4.  Divide by 365 to obtain daily quantities.
                        Multiply by 1.1 to convert to short tons.

-------
          Using  state-by-state production, capacities  as previously given
.and -waste -generation-and hazardous constituent  factors per unit* of
product as previously  given  in Tabl'e  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,.  Extrapolations  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 2.51 predicted
by the industry  over the same-period  (Reference 9).

         , Tables 7a to  7c contain estimates of  the total quantity of
slags from all sources  {blast furnace, EOF, open hearth, electric furnaces,
soaking 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 EOF 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 198'3
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 hot presently recycled.  The remaining 31%
of the dust quantity estitnates_-given in Tables 7g through 7i consist
predominantly of BOF dust with a small-percentage of  open hearth dust.
EOF dust and open hearth dust are not considered potentially hazardous.
                                     25

-------
          Tables 7j through 71 contain estimates of quantities of scale
generated in the iron and steel industry from hot rolling mill, cold
rolling mills, primary mills, and continuous casting mills.  It is esti-
mated that 80% of mill scales are recycled for reclamation o'f iron
content.  The presence of high contents of oil and grease prevents
complete recycle, and for the sane 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
spent 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 also 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, ammonia 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 wastewater treatment plants.  This is environ-
mentally acceptable since the toxic constituents (phenol, cyanide) will
be detoxified in the biological treatment.  Sometimes this waste is dis-
posed of in -'deep wells,

          Ammonia still lime sludge and decanter tank tar are normally
disposed of by open dumping which is not environmentally acceptable
because of the suspectibility to leaching of phenol, cyanide and oils.

Blast Furnace.   Residuals from blast furnaces include slag, dust from
dry emissions control, or sludge from wet emissions controls.  Slag is
usually processed for recovery of iron metal before sale as road fill,

road ballast or building aggregate.   It may be  stored on the ground for
many months or years before use for these purposes.  Flue dust contains
significant concentration of iron and is normally sent to sinter strand
to be agglomerated prior to reprocessing for  iron recovery.  Sludge from
wet emissions control is also  sent to the sinter facility for agglomera-
tion prior 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
per million from these materials which is not considered sufficient to pose
an environmental- threat.

Basic Oxygen Furnace,   Residuals from basic -oxygen furnaces include slag,
dusts from dry emissions controls, sludges frora 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.

Op_en_ Hearth Furnace_s_.  Slag from open hearth  furnaces is usually open
dumped after processing for recovery  of rnetallics.  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 EOF  -
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 dumped1 after recovery of metallies.  A small amount of
slag (approximately 10%) is used as road fill or railroad track ballast.
These methods are adequate since electric furnace slag 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 mills are produced as a result
of water pollution control operations including oil and grease removal,
flocculation and settling of particulates, and  pH 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 are 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'.        .                • •   -

Pickle Liquors.   Currently the prevalent practice employed by steel
plants for handling of waste piclcle 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 andDisposal 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'

-------
 Mill Sludges.    Potentially hazardous sludges are generated from water
 pollution control operations in primary mills,  continuous casting mills,
 hot rolling mills,  cold rolling mills,  galvanizing mills and tin plating
 mills.   Present treatment and disposal  is open dumping which is environ-
 mentally inadequate because of the threat of heavy metal and oil or grease
 leaching.

 Mill Scales.   Potentially hazardous mill scales  are generated in primary
 and 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 well 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 EPA' guidelines.

 1.3.3     Best Technology Currently Employed (Level II)
- Coke Plaiv^.    Level II technology for treatment and disposal of waste
 aimonia 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.

 El ectric_F_urnaces .    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.

           Cold rolling mill  and galvanizing mill sludges are 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 technology for mill
 scales from  primary mills ,  continuous casting mills, hot rolling mills,
 and cold rolling mills is the same as .Level I.
                                      44

-------
 Pick 1-e 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 ProvideAdequate 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
 EPA 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.

 Electric 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 snelting and refining industry.

1.4       COST ANALYSIS

          In the last section various treatment and disposal technologies
currently employed or considered for adequate health and environmental
protection were described.  The costs" o'f implementing this technology for
a typical integrated iron and steel mill complex are estimated in this
section.  Costs of land disposal from individual operations such as steel
furnaces 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
sites 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,froji 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
bulldozer time at the dump.  The dust is piled to a height of S 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 MT 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.

PrimaryandOther Hot Rolling Mill Sludge.   The primary and other hot
rolling mills produce 5739 WT 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

          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.

          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 Pickle Liquor

          Acid regeneration is the Level II treatment for waste pickle
liquor.  Reference 2 indicates a cost of $13/m  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.

technology are shown below.

          Waste Pickle Liquor,

          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 236 1/inin slurry pump is used for dredging.  The pump is operated
350 hrs/yr and 400 hours of labor are assigned to its operation.  Loading
and hauling of the sludge to the dump site requires 265 hrs/yr of front
loader and truck time and 50 hrs/yr of bulldozer time at the sludge dump.

2,1       INDUSTRY CHARACTERIZATION

          The three major groupings of ferrous castings are gray and
ductile dron 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
and include metal melting and pouring, casting shakeout and cleaning and
finishing.

          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
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.

          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
of foundry castings.

2.2       WASTE CHARACTERIZATION

          This section contains descriptions of production technology at
ferrous foundries and the resultant byproducts or wastes which are either
recycled directly, reprocessed, or disposed of on land or in lagoons.

* amount of metal smelted for finished castings exceeds net output of
  castings products.

2.2,1     Process Descriptions

          While specific procedures might vary from foundry to foundry,
the overall operations for producing iron castings, malleable iron
castings, and steel castings are 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 facilitate1their 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 isocyan'ate;
(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 generally1 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.  These materials facilitate removal of
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
(CaC03), fluorspar (mostly CaF_), and soda ash (Naj:)^).  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
are 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
to either the 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 melted rather than on the basis of a ton of finished
castings, because yield factors (weight of finished casting/weight of metal
melted) vary depending on the foundry and the type of metal cast.   For
iron (gray,  ductile and malleable) the yield factor is generally in the
range of 0.6 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  foundry
•would melt  about  11,^000/0.65  » 16,900  tons of metal -per year  (15,300
 metric tons/year).

 Waste Sand.    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  production of the two types  of
 waste'sand  is  330 kg/MT of cast  product.  Although  these.sands have
 different organic additives as described  on page 72 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
 as described in Appendix B did not  show significant leaching  of heavy
 metals or phenol.   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
 of 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.

 Sla£.    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.

-------
 Floorsweepings.    Cleanup of floors  in core 'making  rooms  results in
"sandy floor sweepings  at  aerate 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.

 Refractories.    Broken and weathered brick  refractories from metal
 melting  furnaces are generated at a  rate  of 10- "kg/Ml 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  factors1  .  .   '
 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  the different  types of furnace emission 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-state basis are given  in Table 14 for  1974,  1977,  and 1983.   The quantities
 of sludges and dusts are  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  s/tate  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 compiling sludge and dusts values
for each state might be to multiply the 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.

CoreButts.    Core butts containing non-degraded sands and 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 -orrginating -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 considered 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
need not be addressed at this time.'

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.
                                     96

 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, ferrochronte 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 NTT           32%
          Silicomanganese          139,014    .          6%
          Ferrosilicon             763,305    '    •      33%
          Ferrochrome              319;611      "        14%
          Silvery Iron             147,940              6%
          Other   •                 206,294            .  91

          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 91 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-
 siliconianganese 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

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 basis 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 reraelt.  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-site disposal area.

          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 ferrosilicdn
produced in the United States:  751 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 WT (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
onlyS.S mw-hr per WT.  Inp.ut materials for ferrosilicon production consist
of quartzite, scrap steel, coal, and coke.

          Ferrgchrome Production.    Ferrochrome is made in two grades, high
carbon (HC) and low carbon (LC),  "Most of the-ferrochrome produced -in the
United States is of the high carbon type.  Input materials consist of chromium
ore, quartzite, 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 (US short tons) of
ferrochrome per day.

          Ferronickel.   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, SOI 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
coarser retained ore fractions are calcined and the fines are roasted.
The coarse and fine fractions are then transferred to hot ore bins from
which they are gravity fed to the furnaces.  Ore melting is carried out in
four 20,000 KVA electric furnaces.  The molten nickel ore is tapped 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 pile.

           Ferrosilicon is produced in a 15,000 KVA electric furnace with
.input materials .consisting of quartz, iron turnings,  coke,  wood chips,  and
 skull plant concentrates.  All ferrosilicon produced  is  cast,  crushed and
 used for reduction of the 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     DescriptiTO of Jfaste Streams

 Ferromanganese and Silicomanganese

           Slags.    A dense vesicular slag is generated from ferroraanganese
 production, at a rate of 600 kg/MT ferromanganese product.   Approximately
 360 kg/OT of the  600 kg/NTT generated is used as an input to the silica-
 manganese furnace.  The remaining 240 kg/MT 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 ferroraanganese or
 Silicomanganese slag.  For this reason in addition to the dense nature of
 the slags,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/WT
 of product.  Ninety percent of these emissions or 150.6  kg/Ml 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-inanganese 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 74 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 dumped  at ^ fate of 187.8 kg/OT 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 (9001  lb/ton)' for
 75%  FeSi and 225 kg/MT (450 lb/ton}  for 501 FeSi.  Thus,  for furnaces controlled
 by baghouse  collection systems the average quantity of collected dry dust will
 vary between 405 kg/Ml 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.    -                                                ',

 Ferrochrme
                   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/NfT  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.

           Dust.    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  901.  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 pp'm chrome and around
1 ppra lead.  For this reason dust from ferrochrome emissions control is
considered potentially hazardous at this time.

          Sludg,_e,    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
-------
       •.  .. Dusts.  .  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 furnace  are captured  in  baghouses  and
 recycled to  the furnaces with the exception  of dust  collected from the
 ferrosilicon furnace.  The  ferrosilicon dusts are  collected at  the rate
 of  84  kg/Mr  product,  wetted to prevent 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 Disposaj. 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 sale^as roadfill are environmentally
 adequate since ferromanganese and Silicomanganese  slags are not considered
potentially hazardous at this time.

    - •    - 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 which 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.

          Skul1 P1ant Tai1ings.   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.

          Sludge s.  '  Sludges result from settling of slag granulation
water and  skull plant tailing water in an1-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

-------
           Pus t.    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.

 wastes which are considered potentially hazardous  are  discussed in the
 following  sections.

 3.3.2     PresentTreatment and  Disposal  Technology (Level  I)

 Ferromanganese ajid Silicomanganese

           Sludges  and Dust.   Lime  treated  scrubwater  from  ferromanganese
 furnace emissions  controls  and wet  scrubber sludge from silicoraanganese
 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.

 Ferrochrome      •

           Dusts and Sludges.   Dusts are  open  dumped and scrubber  waters are
 settled in unlined,lagoons  with  periodic  dredging  of settled  sediments.
 Dredged sediments  are open  dumped.   These practices are inadequate because
 of the possibility of heavy metal leaching  and subsequent percolation
 through permeable,  soils to  groundwater.

 Ferronickel
           Skull  Plant  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  skul-l  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,

          Protection (Level III)

Ferromanganese and Siliconiianganese

          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,

Ferroni _ck e 1

          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.

          Ferromanganese and Silicomanganese.   The typical plane produces
81,000 WT 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;

          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 38.7 MT 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.

          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  the  collection  of  15,7 WT of dust/day
 with  a  density of  500-Kg/in  .  The dust is  transported  to an-on-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:

      ,    About 15.2 MT 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,

           Ferrosi1icon.   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 MT 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 MT/d'ay,   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 of the 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.

          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 Silicomanganeje.   The lagoon is lined and the
accumulated sludge is removed by 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.

          Ferrochrome.    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
collection 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 are given in Table 25.

          Ferronickel.    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 pump1 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 26,

          Tables 27 through 29 summarize the capital and annual costs for
Levels I, II and III treatment and disposal technologies for hazardous
land disposed waste from the U.S. ferroalloys industry,  Costs  are 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 III treatment and disposal technology are also given.
Costs for each type of waste and total costs for each ferroalloy sector are
also expressed as1percentages of product selling prices.

          Estimated 1973 annualized industry costs for Levels I and IT
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 0.81 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 0.361 of 1973
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.

 4,0       PRIMARY METAL  PRODUCTS NOT ELSEWHERE CLASSIFIED  (SIC 3399)

          This SIC category includes a number of miscellaneous metal
 products and associated  manufacturing processes including production of
 ferrous and non-ferrous  metal powders, metal paste, and ferrous and non-
 ferrous nails, brads, wire and staples.  Table 30 shows the geographic
 distribution of industries in this SIC category as of 1972.

          Brads, nails,  tacks, spikes and similar items are manufactured
 from metal by machining, extrusion and other similar processes.  Solid
 wastes will consist principally of metal turnings, clippings and other
 metal remnants.  These wastes are recovered for scrap and therefore do
 not constitute a solid or hazardous waste problem.

          Metal powders  are produced by a variety of processes as summarized
 in Table 31.  The raw materials for production is either solid metal or
 chemical compounds of metals - generally oxides of metals.

          The three predominant practices for powder production are
 atomization, gaseous reduction and electrolysis. .Atomization is the most
 widely employed method for manufacturing low-melting metal powders, such
 as tin, lead, zinc, cadmium and aluminum.  Atomization consists essentially
 in forcing a thin stream of molten metal through a small orifice and then
 bombarding it with a stream of compressed gas, which causes the metal to
 disintegrate and solidify into finely divided particles.  Usually the gas
 stream is directed through a nozzle, partly submerged in the molten metal,
 in such a manner as to draw the metal up through the nozzle to the tip.
 Solidification of the metal occurs instantaneously upon contact with the
 gas stream.  The product is then removed by means of a suction system and
 collected in baghouses or cyclone dust collectors.

          Electrolytic production methods for metal powders consist of
 electrolytic deposition  from solution and electrolytic deposition from
 fused salts.  These methods are most suitable for manufacture of extremely
 pure powders of a variety of metals including copper, iron, silver, nickel,
 manganese and chromium.

          Gaseous reduction is employed for the manufacture of "commercial
 quantities of iron and copper powders, the most common metal powders,  and
 less common metal powders including nickel, cobalt, tungsten and molybdenum..
 Hydrogen, carbon monoxide or some other reducing gas is used to reduce
 metallic compounds, usually oxides, to fine metal powders.

          Because either pure metal or metal oxides are used as raw
 materials for metal powder production there is little waste.  Dust, slag
 or sludge residues contain high metallic content and are reprocessed.
 Table 32 which summarizes residual disposition for one of the largest  metal
powder producers in the United States illustrates the dominant practice of
 residual recycle.

       including plant locations, production capacities,  and smelting
       and refining processes, have  been identified and described.
       Land-disposal  or stored residuals have been identified and
       characterized  for 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
       primary metals  industry for the  disposal or storage  of process
       and pollution  control residuals  on land are described.  Methods
       of residual treatment and disposal considered  suitable for adequate
       Health and environmental protection have been  provided.  Finally,
