dusts, others) from each of the metal smelting and refining categories,an
assessment has been made as to whether the wastes are considered either
"non-hazardous" at this time or "potentially hazardous" at this time.
Hazard ratings were made using a number of criteria including the following:
- Types and concentrations of potentially hazardous constituents
(Cd, Cr, Hg, Pb,-Zn, Cu, Niป As, phenol, cyanide, fluoride,
oil and grease}
- Physical characteristics of residuals
- Susceptibility to leaching of potentially hazardous
constituents as indicated in solubility tests described below.
The mere presence of toxic constituents in significant concen-
trations in a waste did not automatically result in a hazardous rating.
The most important criteria was -the tendency of toxic constituents to be
leached from residuals at significant concentrations.
Collected samples of slag, sludges, dusts and other wastes
believed to be representative of wastes discarded or stored by the metal
smelting and refining industries were selected for testing. Particle size
distribution of sludges and dusts were comparable to those encountered at
disposal sites. Particle size distributions of selected slags ranged
from silt size to 1 to 2 inch chunks. Much larger chunks of slag are
found at disposal sites. Selected samples probably represent the more
comminuted fraction of disposed slags and pot liners.
Approximately 50 grams of each sample was placed in a 200 ml jar
and two parts by weight of water added. The bottles were then gently
agitated on a rotary tumbling apparatus (approximately 4 RPM) for a period
of 72 hours. Samples were.then filtered through a 0.45 micron micropore
filter and collected filtrate analyzed for trace, metals and other parameters
of interest. Tables B^l through B-5 give the results of the chemical analyses
of filtrate from the various waste samples after agitation and filtration.
If lead, cadmium, mercury, cyanide, phenol or other highly
toxic materials leached at greater than 1 ppm in solubility tests, the
waste was designated as potentially hazardous at this time.

Some leeway was" allowed depending on "the physical nature of the
waste material and the constituents found to solubilize. Thus many materials
solubilized manganese in the range of a few to 50 or 100 ppm. Leaching of
manganese alone was not considered sufficient reason to designate a waste
as potentially hazardous since manganese is relatively non-toxic. Manganese
is highly abundant in soils and rocks and is present to an average extent of
850 ppm in soils with ranges of 100 to 4,000 ppin (Ref. 1).
Fluoride is beneficial to teeth at low concentrations as evidenced
by the use of fluoridated toothpastes and fluoridated water supplies. The
average concentration of fluorine in soils is 200 ppm with a range of 30
to 300 ppm (Ref. 1). Leaching of fluoride of up to 20 ppm in iron and steel
making slags, sludges, and dusts was not considered sufficient to designate
these wastes as potentially hazardous if "there was less than 1 ppm leaching
of other potentially hazardous constituents.
Although leaching of sodium, potassium and chloride from wastes
would not ordinarily constitute a hazardous waste problem in the metal
smelting and refining industry, the extremely high concentration of these
constituents in "high salt slag" from the secondary aluminum industry and
their high solubility pose a definite threat to groundwater quality. High
salt slag is therefore considered potentially hazardous.
The only residual which leached a heavy metal at significant
concentration and was not considered potentially hazardous at this time was
retort residue from primary zinc smelting. This slag residue leached zinc
at 230 ppm in a solubility test. Zinc is required in human diets at 10-40 ppm
and has low toxicity. Further testing of the leachability of zinc and other
metals from zinc retort residue is needed for further evaluation of toxicity.
The limitations of the solubility tests conducted must be recognized.
Only one solubility test was conducted on each residual. Replications are
desirable to establish statistical significance of test results. The leaching
solution in all cases was distilled water at pH 5,5. Thus no information is
available from these tests on the quality of leachate at lower or higher pH's.

APPENDIX C
COSTS AND COSTS FACTORS FOR TREATMENT AND DISPOSAL TECHNOLOGIES
The predominant practices used in the United States smelting and
refining industry for on land storage or disposal of process and pollution
control residuals are on land storage or disposal of slags, dusts and dredged
sludges, and storage or permanent disposal of slurries and sludges in lagoons.
Practices considered for adequate health and environmental protection include
the use of lined lagoons, chemical fixation of land disposed sludges, soil
sealing at disposal areas and collection of runoff. The basic costing'
assumptions used in estimating the costs of the above practices are described
here. All costs are in 4th quarter 1973 dollars.
Capital Costs ;
Lagoons. Lagoons are assumed to be rectangular in shape with the bottom
length twice the bottom width. The dikes of the lagoons form a 27 angle
with the ground surface. In the construction of the dikes, excavation of
the interior area is to .a depth sufficient to provide all the material
needed for the construction of the dikes. The earth is assumed to be sandy
loam with granular material. The width of the top of the dikes is 3 meters.
Three programs were developed to facilitate the computation of
factors used for estimating lagoon costs.

-------
The initial input is the required lagoon volume. Program No.
2 computes 'the volume of material obtained by excavation to varying
depths. It is used jointly with Program No. 3 to determine the depth
of excavation necessary to provide sufficient material for dike construc-
tion.
Cost categories and cost factors used to estimate lagoon costs
are noted below.

Foot 2
Fine grade finishing 0.45/m (1}
Soil conditioning 1.24/m (3)
Transverse drain fields 4.60/m (1)
Survey is assumed to be performed by standard transit and chain.
The number of test holes drilled is varied as function of lagoon size; at
least two are drilled in all cases. Two soil samples per test hole are
analyzed. Report preparation is assumed to require 1 to 2 engineering
man-weeks depending on the size of the project.
Excavation, forming and compacting costs are based on the
volume of material in the dike. Fine grade finishing is computed from
the dike surface area, i.e. the product of the perimeter of the cross
section of the dike and its circumference. Soil conditioning cost is a
function of the dike circumference.
Drain fields are2designed to monitor lagoon leakage. They
are assumed to be of 1/3 m cross section and are located at;30m centers
along the length of the lagoons. The excavation cost is $1.50/m (1) and
1 m of gravel at a delivered cost of $9.30/m .(1) is used for every
3 m of ditch."
Several cost categories listed for lagoons, such as survey and
excavation and forming, also apply to other facilities. The same unit
costs are employed in these cases.
42
-------
Lagoon Liners. Lining of lagoons is specified for some industries for
Level II and is employed extensively in Level III. There are many candi-
dates for liner material, Hypaloir, a'frequently used liner material, is
selected. Two cost sources (4} and (5) provide ranges of costs for the
purchase and installation of the liner. The two data sources coincide
closely in their estimates. The value selected is $4/m installed.
Other Facilities 5 Activities
Concrete Work. A number of industries use concrete-lined pits for
temporary retention and settling of sludges and slurries. A floor
thickness of about..2 m is assumed for all cases. It's cost-in place
is $15,35/m (1). The required wall thickness is a function of volume
of contained material and is assumed to be 0,4 m1 in this study. Wall
costs are computed on the basis of $243,75/m (1) of concrete in place.
Ground Sealing. Sealing of the ground at dump sites to prevent leaching
is stipulated for many industries as Level III protection. The sealing _
material of choice is bentonite clay. Approximately 14,7 kg/m (3 Ibs/ft )
are worked into the top layer of soil. The FOB cost of bentonite is
$.09/kg ($.04/lb (5). An average transportation cost of $20 MT (0.32/M )
(4) is added.
Installation includes disking, spreading and compacting.
These tasks are assumed to be equivalent to the fine grade finishing
specified in lagoon construction and a cost of $0.45/m is used. The,,
total cost is [($[). 09 x 14.7 kg/m ) + $0.45/m + $0.32/m ] or $2,09/m .
A cost of $2.00/m is used in the study.
^Collection Ditches. Ditches are installed to collect runoff from dump
perimeters. Excavation and installation of 6" perforated, vitrofied
pipe yields a cost of $10.10/m of ditching (1). All open dumps are
assumed to be square; some slanting of the ground is assumed. Unless
specified otherwise, the' length of ditching installed equals 1.5 x 1 side
of the dump area.
Pumps and piping to transport the collected water are discussed
under stationary equipment.
Railroad Track. Intra-plant rail transport is employed by some industries
to haul solid or liquid waste from the plant to an on-site dump. The
construction cost for 1 km of track is shown below. It is a single track
on level ground.

The width of the sub-base is assumed to be 4 m. The miscellaneous
bulldozing represents 2 days work and movement of about 860 m of earth.
Road Construction. A 'road must be provided where waste transport is in
by truck in lieu of rail. The cost of constructing a gravel .road 1 km
in length is as follows:

Total $ 32,550/km
The road width is 6 m. A base course of gravel about .3 m deep is applied
and compacted. Culverts, each 6 m in length, are assumed to be required
every 100 in. Drainage ditches are provided for a distance of .5 km along
both sides of the road. The miscellaneous bulldozing is the same as is
included for railroad track construction.
Stationary Equipment
Slurry Pump. Slurry pumps can be used in lieu of draglines 'for
dredging lagoons. The selected slurry pump has a capacity of 236 liters
per minute and is powered by a 2 hp motor. Its cost including housing,
installation, wiring and piping is $13,730 (6).
Both rigid, installed and flexible piping are used. Both
are 7.6 {3" pipe). Their costs/in are $17,30 (1) and $4.40 (1), respectively.
Other Pumps. The main application of other pumps is at the on-site
slag dumps to pump collected runoff water. Centrifugal pumps requiring
no attendants are used. The pump capacities are selected as a function
of the size of the dump. They are sized to handle a volume of water
equivalent to a 2.5 cm rainfall/hr over the dump area.
44
-------
The pump'Costs are based on Reference (7). A 3 m head is
assumed. -Piping costs-associated with-the-pumps include 100 m-each of
rigid, installed and flexible pipe. Horsepower requirements for "other
pumps" are computed as follows:
Hp ( GPM x H
3960 x E
where
HP = Horsepower
GPM = Gallons/ntin
H = Head (assumed to be 9.8 ft (3 m)
E = Efficiency (assumed to be = .9)
Belt Conveyors. A belt conveyor is used in one industry to transport
slag to a slag pile. A number of conveyors are positioned in series
.because of the distance involved. A 36" wide belt conveyor was found
sufficient to handle the waste produced. Its cost, is $44,545/30 m
(100 ft) section, installed (Ref. 7 and 9).
Mobile Equipment. Generic equipment types are identified and costed
for handling and trasnporting waste,products. These do not necessarily
represent optimum equipment in terms of capacity, power or cost. Equip-
ment specified includes:
Ref.
Dump truck (16-18 t) $ 25,000 (2)
Tank truck ' 40,000 (2)
Front loader and backhoe 20,000 (similar to JD-410)
Bulldozer 16,000 (similar to JD-350)
Dragline with 3/4 yd clam shell 70,000 (2)
Yard engine (industrial) 30,000 (used) , (2).
Hopper car (45 t) _ 5,000 (used) , (2)
Ladle car (10,8 m ) . 40,000 (2)
Many plants do not require particular equipment full time for
waste handling and transport. The approximate fraction of time a piece,
of equipment is actually needed for these purposes is determined and
the capital cost is assigned accordingly,. It is assumed that the equip-
ment is engaged in other plant activities the remainder of the time.
The fraction of use is based on an 8 hour/day or 2,00,0 hr/yr equipment
availability.
Land. Three categories of land are considered. They are shown below
together with their estimated costs.

Rural $ 1,750/ha- (6)
Semi-industrial 3,955/ha (6)
Improved industrial 24,710/ha (6)
Annual Costs
Lagoons, Construction and Other Facilities. A twenty year useful life
and a corresponding amortization period are postulated. It is assumed
that equal quarterly payments are made throughout this time resulting
in the following annual cost.

1 + ฃ
m
where
f V
("I)
A = Annual amortization cost
B = Initial' amount
r = True annual interest rate (10%)
m = Mo. of payments per year (4/year)
N = No. of years .(20 years]
The computed annual cost essentially represents the sum of the cost
of capital and depreciation,
Additionally, a cost category" is included for the repair
and maintenance of lagoons, facilities and other construction. This
cost is estimated to be 3 percent annually of initial construction cost
(excluding site preparation) except for railroad tracks and roadways
for which a 5 per cent annual rate is used. -
Mobile .and Stationary Equipment. Annual equipment costs are 'treated
in the same manner as lagoons, construction and other facilities. A
ten year useful life is assumed for stationary and -road mobile equip-
ment and a twenty year life for railroad equipment. Pumps and
piping are considered stationary equipment.
The annual maintenance and repair cost is estimated as 5 per cent
of initial purchase (7) cost exclusive of fuel and operating personnel.
Land. Annual land cost represents an opportunity cost. It is on 10
per cent of initial acquisition cost. Survey costs associated with land
used for slag and other dumps are added to and amortized together with
lagoon construction and other facility costs.
46
-------
Operating Personnel. Waste handling and transport is performed by
two labor grades: heavy equipment operator and truck driver/laborer.
The applicable hourly wage rates are $12.15 (1) and $9.45 (1) respectively.
The rates include fringe benefits, overhead and supervision.
Personnel costs are charged only for the hours such personnel
are actually handling and transporting wastes. It is assumed that personnel
will be employed in other plant activities the remainder of their time,
Energy. Energy costs are divided into two categories: fuel and
electricity. All mobile equipment is assumed equipped with diesel engines.
Fuel consumption by a particular equipment unit can vary widely depending
on its operational use. Based on a brief review of engine specifications
the following mean fuel consumption values were determined.
Trucks 4 Gal/Hr
Bulldozer 2.4 Gal/Hr
Front loader and backhoe 2.85 Gal/Hr
Dragline with 3/4 yd clam
shell 2.85 Gal/Hr
Yard engine . 8 Gal/Hr
The cost of fuel is $0.40/gal.
The cost of miscellaneous electric energy, (e.g. lighting) is
estimated at 10 per cent of fuel cost.
The power cost of electric equipment, where specified, is
computed separately as follows:
horsepower of motor x
Cost per horsepower year = 0.9 (efficiency) x 0.9 (power factor)
0.7457 x No. of yearly operating hours x cost per kilowatt hour.
A kilowatt hour cost of $0.012 is assumed.
Chem-Fix Operation. Chemical fixation where employed is shown as an
annual cost. At this time, no data was found describing capital costs to
establish this process for various sizes of operations. The cost of
$13.20/tn of waste treated which is used in the study reflects current
experience (10).
Taxes. Taxes are computed as 2.5 per cent of the cost of land (6).
Insurance. Annual insurance premiums are 1 per cent of the capital
cost ^(6).

APPENDIX D
PROCEDURES FOR CALCULATING WASTE QUANTITIES FOR THE IRON AND STEEL INDUSTRY
This appendix uses the -iron and steel industry as an illustrative
example of the methodology employed to estimate the quantities of wastes
and potentially hazardous constituents therein. Similar procedures were
employed for estimating waste quantities in the other primary and secondary
smelting and refining sectors. Most of the data required for calculating
the amounts,, of wastes generated by iron and steel mills were derived from:
1) the collection and analysis of waste samples; 2) information provided
by environmental control personnel at ten participating steel mills;
3) the Iron and Steel Works Directory of the United States and' Canada
(1974); and 4) the Annual Statistical Report, American Iron and Steel
Institute (1973). _ The-Directory and the Annual Statistical Report'were
used primarily in estimating the production of various types of facilities
by state. -
Through the cooperation of the American Iron and Steel Institute,
arrangements were made to have ten integrated steel plants participate in
a program to collect waste samples from selected facilities on a daily
basis over a four week period, and to provide .quantitative, information on
the amounts of waste generated. Each of the ten plants was visited to
discuss the types of waste generated and to identify 10 to 15 waste sources
to be included in the sampling program. The waste samples were collected
by steel plant personnel and forwarded to Calspan Corporation for analysis.
Wastes of each type were composited on a weekly basis, so that for each
plant, four composite samples (one for each week of the sampling program)
were obtained for each type of waste of interest. The analyses included
determinations of chromium, copper, manganese, nickel, lead, zinc, cyanide,
fluorine, oil and grease, and phenol. For any given waste type (e.g.,
electric furnace dust) the concentration values were averaged over all
plants and over all composites.
j
.Subsequent to each plant visit, a form indicating desired
information on the quantities of waste generated was prepared and sent to
the environmental control manager. Specific information of interest was
the total annual production for each facility and the amounts of waste of
each type produced (e.g., dust, sludge, slag). The data provided from
all plants were analyzed and average waste generation factors were obtained.
Table D-l summarizes the averaged data for the quantities of each waste
type generated and the concentrations of constituents of interest.
The production data for the major steel plant products (e.g., pig
iron, ingot steel, cold rolled steel, etc.) and the waste generation
factors for the associated facilities allows the total waste quantities to
be determined. Data for a "typical" plant were presented in the main text
and are reproduced here as Table D-2. Thus, for example, the yearly
quantity of basic oxygen furnace slag for a typical plant is calculated as;

In order to calculate waste generation quantities on a state-by-
state basis, production figures for various product types had to be deter-
mined. Since such data were not directly available, estimates had to be
generated. For each state, iron 'and steel production and/or processing
facilities were tabulated using the Iron and Steel Works Directoryof the
United States and Canada (1974). From the size and number of facilities
of each type listed for all plants in a given state, production figures
were estimated for that' state. These figures were summed 'over all states
and comparisons made with total U.S. production data presented in the
'Annual Statistical Report, AmericanIron and Steel Institute. The figures
for the individual states were then adjusted to make the national total
agree with the published national figures.
The wastes for the state totals were grouped into five categories;
slag; dust; sludge; scale; and pickle liquor. The sources for each waste
category are listed in Table D-3, In computing the total quantities of
waste in each category for each state, the waste factors.discussed pre-
viously were used with weighting factors as appropriate. The weighting
factors are necessary in some cases to account for the fact that any one
type of facility might produce different waste types depending on the type
of control system used. For example, basic oxygen furnaces might employ
dry- or wet-type emission control systems. A dry system produces dust-
type waste, whereas, a wet system produces a sludge-type waste. Therefore,
in order to calculate the amounts of dust and sludge produced by BOF

facilities given the total amount of steel produced in BOF's, the percentages
of steel made in BOF's using wet emission control systems and dry control
systems must be known. The weighted waste generation factors were then
computed by multiplying the waste generation factor for a given type of
waste (see Table D-l) by the fraction of product made using that type of
control system. The required fractions were estimated from data obtained
from the participating plants.
For the final determinations of total wastes (and their constituents}
for each state, a program was written to allow the required summations to be
computerized. The computed waste values are given as
- n
w. = T" f. c., P,
k r_ , i ik i
where W is the amount of constituent of type k, f. is the weighted waste
generation factor for the i source (or facility], c.. is. the concentration
of the k constituent in the waste generated by the i source, and
P. is the total annual state-wide production of facilities of the i type.
Trie total waste quantities, as opposed to the individual constituents,
correspond to c., = 1.
To illustrate the application of the above equation, let us
consider a specific example for the iron and steel industry, namely,,the
amounts of dust generated in Pennsylvania. The four major sources of waste
dust in the production of iron and steel are: blast furnaces, basic oxygen
furnaces, open hearth furnaces and electric furnaces. Table D-4 lists the
estimated 1974 production figures (P) for the State of Pennsylvania for each
of these facilities and indicates the type of dust. The raw generation
factors listed for waste dust are those given in Table D-l. _ The weighted
dust factors (f) were obtained by multiplying the raw waste factors by a
fraction representing the estimated percentage of the facilities of each
type that utilize dry emission control systems. Specifically, it is
estimated that 35 percent of the BOF's, 75 to 80 percent of the open hearths,
and 90 percent of the electric furnaces control emissions with dry systems.
In the case of blast furnace flue dust and EOF "kish", the raw generation
factors were assumed to apply to all facilities. The chromium concentra-
tions (C ) for each of the listed dusts are also .given in the Table,
In accorance with the equation given above, the amount of each
dust type for a given facility is determined by taking the product
W = P x f x C, with C = 1. Thus, to determine the amount of blast furnace
flue dust, we compute (21,160,000 metric tons) x (0.0162) = 342,792 metric
tons. To determine the amount of chromium in this amount of blast furnace
flue dust, we take the product W = P x f x GC = (21,160,000) x (0.0162) x
(92.4x10" ) = 31.67 MT. Similarly, we obtaincthe amounts of dusts and the
associated chromium content for all of the indicated dust types. The total

dust is the sum of the amounts for "the individual facilities^. After rounding,
we find the total amount of dust generated in 1974 by integrated iron and
steel mills in Pennsylvania to be 607,000 metric tons. The corresponding
chromium content of this dust is 201 metric tons. In a similar manner, we
determine the amounts of other constituents of interest, namely, copper,
manganese, nickel, lead, zinc, cyanide, fluorine, and phenol. The total
amount of "potentially hazardous constituents" is then the sum of the
individual constituents.
