Exhibit 3-4 presents VOCs resulting from coating
operations used in the manufacture of two-piece
cans-
Exhibit 3-5 presents VOCs resulting from sheet
coating operations used in the manufacture of
three-piece cans.
Exhibit 3-6 presents VOCs resulting from typical
three-piece can assembly operations.
3.3.3 RACT Guidelines
The RACT guidelines for VOC emission control are specified
as the amount of allowable VOC, in pounds per gallon of coating,
minus any water in the solvent system. To achieve this
guideline, RACT suggests the following options:
Low solvent coatings
Waterborne
High solids
Powder coating
Ultraviolet curing of high solids coatings
Incineration
Carbon adsorption.
The RACT guidelines have established different limitations
for each of four groups of can coating operations. Exhibit
3-7, following Exhibit 3-6, presents the recommended VOC
limitations, compared with typical, currently available, conven-
tional coatings.
3.3.4 Selection of the Most Likely RACT Alternatives
Projecting the most likely industry response for control
of VOC emissions in can manufacturing facilities is complicated
by the thousands of different products offered by the can
industry. Several general assumptions can be made.
The industry preferred response will be to use low
solvent coatings (primarily waterborne) wherever
technically feasible.

The choice between thermal incinerators
and catalytic incinerators will be based
on the availability of fuel and the pref-
erence of the individual companies.
Incinerators with primary heat recovery
will be used in preference to those with
secondary recovery or no heat recovery.
The industry will not install carbon adsorption
systems because of the very poor performance record
established to date.
Eight likely control alternatives, as well as two
base cases, are discussed in the paragraphs below.
The percentage of cans likely to be manufactured by
each of the control option alternatives, by 1982, is
summarized in Exhibit 3-8, on the following page.
The resulting emissions are summarized in Exhibit
3-9, at the end of this section. For cases involving
incineration, the following assumptions were made.
Energy cost is $2.25 per million BTUs.
Capital cost is $20,000 per CFM.
Incinerators operate at 10 percent of the lower
explosive limit.
90 percent of the roller coating emissions are
collected and incinerated.
30 percent of the interior spray coating emissions
are collected and incinerated.
3.3.4.1 Three-Piece Beer and Soft Drink Cans—Base Case
At the present time, the majority of three-piece beer
and soft drink cans are produced by the following coating
operations:
Interior base coat
Decoration and over varnish
Interior and exterior stripe
Interior spray coating
End sealant.

-------
The production of beer cans differs from the production of
soft drink cans in some respects, the impact of which has not been
considered in this study.
Beer cans almost always have an exterior stripe,
but soft drink cans frequently do not.
Beer cans always have an inside spray coating but
soft drink cans usually do not. However, soft
drink cans frequently have a heavier inside base
coat to offset the elimination of the spray
coating.
Consideration of these differences has been elminated to reduce
the complexity of the study. Because of the declining importance
of three-piece beer and beverage cans, the impact will be smaller
in 1982 than it would be currently.
The total emissions from this alternative are 1.79 tons
per million cans (2.5 times the emissions from a similar two-
piece can) .
3.3.4.2 Three-Piece Beer and Soft Drink Cans—Waterborne
Coatings as Proposed in RACT
In this alternative, all the coating operations currently
employed in the base case have been converted to waterborne
coatings. The cost of converting to waterborne systems was
assumed to be minimal.
The capital cost for converting each of five
coating operations was assumed to be $10,000.
This results in an annualized capital cost of
$104 per million cans—assuming that the cost of
capital and maintenance is 25 percent of the total
installed capital cost and that 120 million cans
are produced annually on the coating line.
The raw material cost of coatings is the same as
for conventional coatings.
The energy consumption is the same—this would
appear reasonable since most of the energy is
consumed to heat the wickets and belts and also
the can metal.
-'-Annualized capital cost includes depreciation, interest
taxes, insurance and maintenance.
3-12
-------
The yield (spoilage) is the same—it appears that
the industry will continue to encounter signi-
ficant spoilage in changing over to new coatings.
However, as the technology is established, it is
assumed that spoilage will decline to currently
acceptable levels.
The total incremental cost to convert to waterborne
coatings is estimated to be about $100 per million cans.
This represents a cost increase of about 0.15 percent. The
emissions would be reduced to 0.34 tons per million cans, an
8 0 percent reduction, at a cost of about $72 per ton.
It is estimated that 25 percent of all beer and soft
drink facilities will employ this option. The acceptance of
this technology will be retarded by the lack of a complete
line of available coatings.
3.3.4.3 Three-Piece Beer and Soft Drink Cans—Base Case with
Thermal Incinerators and Primary Heat Recovery
This alternative assumes that all coating operations
currently employed in the base case are retrofitted with
thermal incinerators. Several thermal incinerators
are currently being employed on coating lines in Alabama.
The capital required for five incinerators would be
about $320,000—assuming an installed cost of $20,000 per CFM.
The annualized capital cost would be about $668
per million cans.
The energy cost to operate the incinerators would
be $166 per million cans.
The material costs would be the same as the base
case.
The total incremental cost of adopting thermal in-
cineration is estimated to be about $8 34 per million cans.
This represents a cost increase of about 0.2 percent. The
emissions would be reduced by 59 percent to 0.74 tons per
million cans, at a cost of $794 per ton of emissions
removed. Because of the prohibitively high costs of this
alternative, it is estimated that it will be employed only
on 20 percent of all three-piece beer and soft drink cans
manufactured in Alabama in 1982.
3-13
-------
3.3.4.4 Three-Piece Beer and Soft Drink Cans—All Waterborne
Except End Sealant, Which Is Thermally Incinerated
It is likely that the can industry will adopt a hybrid
system, which will focus on waterborne or possibly other
low solvent coatings and thermal incineration of the end
sealant and which probably will not be universally available
by 1982. Because end sealing compounds represent approximately
12 percent of the VOC from three-piece beer and soft drink can
manufacture, this case was developed under the assumption that
technology-based exceptions will not be granted.
The capital cost of converting four coating
operations and adding one incinerator would be
about $340 per million cans.
The additional energy costs of one incinerator
would be about $9 3 per million cans.
Material cost would be the same.
The total incremental cost of this scenario would be
about $171 per million cans. This represents a cost in-
crease of about 0.2 percent, to reduce emissions by 80
percent. It is estimated that about 55 percent of the beer
and soft drink cans will be produced using this technology.
3.3.4.5 Three-Piece Food Cans—Base Case
Three-piece food cans are currently produced
utilizing the following coating operations:
Interior base coat
Exterior base coat
Interior stripe
End sealant.
The emissions from this case are estimated to be 0.99
tons per million cans.
3.3.4.6 Three-Piece Food Cans--Waterborne as Proposed in RACT
In this alternative, all the coating operations
currently employed in the base case have been converted to
waterborne coatings.
3-14
-------
The total incremental cost to convert to waterborne
coatings is estimated to be $113 per million cans. A 76
percent reduction in emissions is achieved, to 0.24 tons per
million cans. It is unlikely that a complete spectrum of
waterborne coatings will be available to meet industry
requirements by 1982 because:
The focus of research is on two-piece beer and
soft drink cans, which is the most rapidly
growing market segment.
The need to achieve FDA approval for the broad
spectrum of products required has caused coating
manufacturers to focus on the large-volume coatings
required for beer and soft drinks.
As a result, it is estimated that only 25 percent of
the cans will be produced using this control approach.
3.3.4.7 Three-Piece Food Cans—Base Case with Thermal
Incinerators and Primary Heat Recovery
This alternative assumes that all coating operations
currently employed in the base case are retrofitted with thermal
incinerators.
The total incremental cost of adopting this approach is
estimated to be about $690 per million cans; about $595
in capital cost and $95 in energy costs. Emissions
would be reduced by 81 percent, to 0.19 tons per million
cans. An estimated 2 0 percent of the cans would be produced
using this approach.
3.3.4.8 Three-Piece Food Cans—All Waterborne Except
End Sealant, Which Is Thermally Incinerated
Because waterborne and other low solvent coatings
are not available, it is likely that the industry will
develop a hybrid approach utilizing waterborne coatings
where available and incinerating the balance of the emissions.
The end sealing compound appears to be the coating most likely
to be unavailable in low solvent form by 1982—end sealing
compounds release about 18 percent of the VOC emissions from
food can manufacturing operations.
The total incremental cost of this scenario is about
$200 per million cans; $500 in capital cost and $100 in
energy costs. The emissions are reduced by about 79 percent
to 0.25 tons per million cans. It is estimated that 55 percent
of the cans would be produced using this approach.
3-15
-------
3.3.4.9 Sheet Coating Feeder Plant—Low Solvent As
Proposed in RACT
In this alternative, all the sheet coating and end
compounding operations will be converted to waterborne. The
total incremental cost to convert to waterborne is estimated
to be about $15 per million cans. It is unlikely that a
complete spectrum of waterborne coatings will be available
to meet industry requirements by 1982; as a result, 40 percent
of the stock will be coated with waterborne coatings.
3.3.4.10 Sheet Coating Feeder Plant—Thermal Incinerators
And Primary Heat Recovery
This alternative assumes that all sheet coating
and end compounding lines are retrofitted with incinerators.
At the present time, a significant number of sheet coating lines
in Alabama already are operating incinerators. Because of the
already installed incinerators and the lack of a complete
spectrum of coatings, it is estimated that 60 percent of the
stock will be coated using thermal incinerators for VOC control.

3.4 COST AND VOC BENEFIT EVALUATIONS FOR THE MOST LIKELY
RACT ALTERNATIVES
Costs for alternative VOC emission controls are presented
in this section based upon the costs per million cans developed
for each alternative in the previous section. The extrapolation
is based upon can production and emission for actual can
manufacturing processes and not upon the representative plants.
3.4.1 Costs for Alternative Control Systems
Although there is no typical can manufacturing facility,
the following two representative plants describe the situation
in most three-piece can manufacturing facilities in Alabama.
Representative Plant A produces 50 percent three-
piece beer and soft drink cans and 50 percent three-
piece food cans using two assembly lines. The
sheet coating lines operate at 2.5 base boxes per
minute for about 1,500 hours per year, to support
the assembly line. Each can assembly line
operates at 400 cans per minute, for 2,000 hours
annually.
Representative Plant B coats and decorates flat
stock for use in satellite assembly plants. The
plant coats at 2.5 base boxes per minute. Its
operating rate is approximately 1,000 hours per
satellite plant production line. Assuming the
plant supports four lines, its operating rate would
be 4,000 hours annually.
3-17
-------
The capital cost to adopt the alternative controls to the
representative plants ranges from $30,000 (to convert the
sheet coating plant to waterborne coatings) to more than $300,00 0
(to retrofit the three-piece coating and assembly plant with
incinerators). The incremental operating costs (energy plus
25 percent of capital) range from $8,000 (coating plant converted
to waterborne coating) to a cost of $177,000 (for operating inciner-
ators at the three-piece coating and assembly plant). Capital and
annual operating costs for each of the representative plants
is presented for each applicable alternative on Exhibit 3-10,
on the following page.
3.4.2 Extrapolation of the Costs to the Statewide Industry
Exhibit 3-11, following Exhibit 3-10, shows an extrapolation
of the costs of VOC emission control to the state of Alabama.
The costs are based upon:
The estimates of the cost of compliance for each
of the coating operations that were developed in
section 3.3
An estimate of the share of the market for each type
of can manufactured
The assumption that coated stock sufficient to
produce an additional 2.4 billion cans is shipped
from Alabama to other states.
Based on the above assumptions and assuming that the
industry currently is not controlling emissions, the total
capital required to reduce emissions to meet the RACT guide-
lines from the uncontrolled level would be about $1.1 million.
The annual compliance cost would be about $0.5 million.
Emissions from the Alabama can manufacturing industry
were reduced by an estimated 1,200 tons per year by the end
of 1977, through control approaches acceptable under RACT—
incineration.
The industry currently is spending more on controls than
they are likely to in 1982, assuming the industry substantially
increases its usage of waterborne coatings. However, it is
entirely possible that, in the face of falling demand for three-
piece cans, manufacturers will shut down some capacity and use
existing incinerators on remaining capacity.

3.5 DIRECT ECONOMIC IMPLICATIONS
This section presents the direct economic implications
of implementing RACT controls to the statewide industry, in-
cluding: availability of equipment and capital; feasibility
of the control technology; and impact on economic indicators,
such as value of shipments, unit price, state economic
variables and capital investment.
3.5.1 RACT Timing
RACT must be implemented statewide by January 1, 1982.
This implies that can manufacturers must have either low
solvent- coatings or VOC control equipment installed and
operating within the next four years. The timing of RACT
imposes several requirements on can manufacturers including:
Obtaining development quantities of low solvent
coatings from their suppliers and having them approved
by their customers
Having coating makers obtain FDA approval where
necessary
Obtaining low solvent coatings in sufficient
quantity to meet their volume requirements
Acquiring the necessary VOC control equipment
Installing and testing incinerators or other VOC
control equipment to insure that the system
complies with RACT.
The sections which follow discuss the feasibility and the economic
implications of implementing RACT within the required timeframe.
3.5.2 Feasibility Issues
Technical and economic feasibility issues implementing
RACT controls are discussed in this section.
The can manufacturing industry, in conjunction with coating
suppliers and incinerator vendors, has extensively evaluated
most of the approaches to meeting RACT. The feeling in the
industry is that, except for one notable exception, RACT can be
achieved by January 1, 1982, using low solvent coatings--
primarily waterborne. The coating most likely to be unavailable
in 1982 is the end sealing compound. The physical characteristics
of this material, as well as its method of application, do not lend
themselves to incineration. Currently, the coating is air dried
over a period of 24 hours.
3-19
-------
The can manufacturers have shut down a significant number
of three-piece can manufacturing facilities. It appears likely
that the implementation of RACT will accelerate this trend,
because of the lower cost of compliance with two-piece cans and the
probable reluctance on the part of can manufacturers to invest
capital in facilities producing products with declining demand.
3.5.3 Comparison of Direct Cost with Selected Direct
Economic Indicators
This section presents a comparison of the net increase
in the annual operating cost of implementing RACT with
the total value of cans sold in the state, the value of
wholesale trade in the state and the unit price of cans.
The net incremental operating cost from the uncontrolled
level to can manufacturers is estimated to be $0.5 million
(0.4 percent) of current manufacturing costs. The future
economic impact on the industry is likely to be considerably
less than $0.5 million because of considerable controls already
in place — and in fact, will probably not exceed $20,000 from
the current level.
3.5.4 Ancillary Issues Relating to the Impact of RACT
This section presents two related issues that were developed
during the study.
The can manufacturers have succeeded in having the guidelines
altered to encompass a plant-wide emissions basis. This allows
a credit from one operation, where emissions were reduced to below
the RACT recommended level, to be applied to another operation that
is not in compliance. The plant would be in compliance if the
total emissions were reduced to the level proposed in RACT. It
appears that the impact of this regulation would be to further
concentrate the difficult-to-control emissions, such as end sealing
compounds, into the largest facilities and to reduce further the
number of can assembly plants.
High solvent coatings represent a considerable fire hazard.
The conversion to low solvent coatings has reduced fire insurance
costs for at least one can manufacturing facility.

the current economic implications of implementing RACT for can
manufacturing plants in the State of Alabama.

4.1 SPECIFIC METHODOLOGY
This section describes the methodology for estimating:
Industry statistics
VOC emissions
Processes for controlling VOC emissions
Cost of controlling VOC emissions
Economic impact of emission control
for surface coating of metal furniture in Alabama.
The quality of the estimates is described in detail
in the last part of this section.
4.1.1 Industry Statistics
Industry statistics on metal furniture manufacturing
plants were obtained from several sources. All data were
converted to a base year 1977, based on specific scaling
factors. The number of establishments for 1977 was based
on the Solvent Emissions from Stationary Sources in Alabama;
and supplemented by a review of the 1976 County Business
Patterns and interviews with selected metal furniture
manufacturing corporations. The number of employees was
obtained from the 1976 County Business Patterns and refined
based on information obtained during interviews with
selected metal furniture manufacturers.
The industry value of shipments was estimated by
scaling up 1972 and 197 6 published data to 1977. Because
of the lack of uniform data, different approaches were used
for the household and business/institutional furniture
subcategories of this industry, as discussed below.
4.1.1.1 Value of Shipments for Household Metal
Furniture
Predicasts Inc. (Issue #64, July 27, 1976) presented
the 1976 U.S. value of shipments of household metal
furniture (SIC 2514) as $1,161 million and indicated an
8.7 percent increase in the value of shipments for 1977.
The 1972 Census of Manufactures reported that the value
of shipments in the East South Central region was $152
million, or 21 percent of the U.S. value of shipments.
The value of shipments for household metal furniture in
Alabama was reported as $22.0 million, or 14.5 percent
of the regional value of shipments.
4-2
-------
The 1977 value of shipments of metal household furniture
in Alabama was estimated by scaling up the 197 6 U.S. value
of shipments to 1977 and- applying the above regional and
state percentages.
4.1.1.2 Value of Shipments for Business/Institutional
Metal Furniture
Business/institutional metal furniture includes office
furniture (SIC 2522), metal partitions (SIC 2542) and public
building furniture (SIC 2531). The value of shipments was
estimated using the following technique:
For office furniture, the 1976 Current Industrial
Reports presented the U.S. value of shipments as
$1,002 million and Predicasts Inc., Issue #64, July
27, 1976 indicated an 8 percent increase in the value
of shipments for 1977. The value of shipments for
Alabama was reported as $15.7 million in the 1976
Census of Manufactures, which was 1.85 percent of the
U.S. value of shipments. The 1977 value of shipments
for Alabama was estimated by applying this percentage
to the 19 77 U.S. value of shipments.
For metal partitions, which also include shelving,
lockers, storage racks and accessories and miscel-
laneous fixtures, the 1972 Census of Manufactures
reported the value of shipments for Alabama as
$14 million. The 1977 value of shipments was
estimated by assuming a 6 percent linear rate of
growth between 1972 and 1977.
For public building furniture, which includes metal,
wood and plastic furniture for stadiums, schools
and other public buildings, the 19 72 Census of
Manufactures reported the U.S. value of shipments
ai $546.9 million and the value of shipments for
the East South Central region as $35.7 million.
The value of shipments for Alabama was reported as
$3.2 million. The breakdown among metal, wood and
plastic furniture was not reported. Because of
the lack of data on the breakdown among metal
and other types, half of the total value of ship-
ments was assumed to be for metal furniture. The
1977 value of shipments was estimated by assuming
a 6 percent linear rate of growth between 1972
and 1977.

4.1.2 VOC Emissions
The VOC emissions were obtained from the Alabama Air
Pollution Control Commission's emissions inventory, except
for one facility where the annual throughput of coatings was
used to estimate the emissions. Current VOC emissions controls
were determined through interviews with plant operations.
4.1.3 Processes for Controlling VOC Emissions
Processes for controlling VOC emissions for metal
furniture plants are described in Control of Volatile
Organic Emissions from Existing Stationary Sources,
EPA-450/2-77-032. The data provide the alternatives
available for controlling VOC emissions from metal fur-
niture manufacturing plants. Several studies of VOC
emission control were also analyzed in detail, and metal
furniture manufacturers were interviewed to ascertain the
most likely types of control techniques to be used in
metal furniture manufacturing plants in Alabama. The
specific studies analyzed were Air Pollution Control
Engineering and Cost Study of General Surface Coating
Industry, Second Interim Report, Springborn Laboratories,
and informational literature supplied by the metal furni-
ture manufacturers.
4.1.4 Cost of Controlling VOC Emissions for Surface
Coating of Metal Furniture
The costs of control of volatile organic emissions
for surface coating of metal furniture were developed by:
Determining the alternative types of control
systems likely to be used
Estimating the probable use of each type of
control system
Defining equipment components
Developing installed capital costs for each
alternative control system
Aggregating installed capital costs for each
alternative control system
Defining two model plants
4-
-------
Developing costs of a control system for the
model plants:
Installed capital cost
- Direct operating cost
- Annual capital charges
Energy requirements
Extrapolating model costs to individual industry
sectors
Aggregating costs to the total industry for the
state.
The model plants used as the basis for estimating the
costs of meeting RACT were solvent-based dipping and elec-
trostatic spraying operations. The cost of modifications
to handle waterborne or high solids was not considered to be
a function of the type of metal furniture to be coated,
since no modifications to the production lines should be necessary.
Modifications are required only to the coatings handling
and pumping and spraying equipment, and these would probably not
differ for different types of furniture pieces.
4.1.5 Economic Impacts
The economic impacts were assessed in terms of analyzing the
lead time requirements to implement RACT, assessing the
feasibility of instituting RACT controls in terms of capi-
tal availability and equipment availability, comparing the
direct costs of RACT control to various state economic
indicators and assessing the secondary effects on market
structure, employment and productivity as a result of
implementing RACT controls in Alabama.
4.1.6 Quality of Estimates
Several sources of information were utilized in asses-
sing the emissions, cost and economic impact of implementing
RACT controls on the surface coating of metal furniture in
Alabama. A rating scheme is presented in this section to
indicate the quality of the data available for use in this
study. A rating of "A" indicates hard data (data that are
published for the base year), "B" indicates data that were
extrapolated from hard data and "C" indicates data that were
not available in secondary literature and were estimated based
on interviews, analysis or previous studies and best engineer-
ing judgment. Exhibit 4-1, on the following page, rates each

4.2 INDUSTRY STATISTICS
Industry characteristics, statistics and business trends
for metal furniture manufacturing plants in Alabama are
presented in this section. Data in this section form the
basis for assessing the impact of implementing RACT for con-
trol of VOC emissions from metal furniture manufacturing
plants in the state.
4.2.1 Industry Characteristics
Metal furniture is manufactured for both indoor and
outdoor use and may be divided into two general catego-
ries: office or business and institutional, and
household. Business and institutional furniture is manu-
factured for use in hospitals, schools, athletic stadiums,
restaurants, laboratories and other types of institutions,
and government and private offices. Household metal furni-
ture is manufactured primarily for home and general office
use.
4.2.2 Size of Industry
The Alabama Air Pollution Control Commission reports
and Booz, Allen interviews have identified four companies with
five plants in Alabama, participating in the manufacture and
coating of metal furniture, as shown in Exhibit 4-2, on the
following page. Statewide, the metal furniture industry in
Alabama accounted for an estimated $38 million in household
metal furniture shipments and $40 million.in business/insti-
tutional metal furniture shipments in 1977. This is equiva-
lent to about 3 percent and 1.7 percent of the U.S. value of
shipments of household and business/institutional metal furni-
ture, respectively. The metal furniture industry in Alabama
employs approximately 2,600 persons. Since the five plants
affected by RACT account,for approximately 1,600 employees
(or 62 percent) of the industry, it is assumed that these
five firms also account for approximately 62 percent of the
value of shipments.
4.2.3 Comparison of the Industry to the State Economy
A comparison of the value of shipments of metal
furniture with the state economy indicates that the metal
furniture industry represents about 0.4 percent of the
total Alabama value of shipments of all manufactured
goods. The industry employs approximately 0.8 percent of
all people employed in manufacturing in Alabama.

4.3 THE TECHNICAL SITUATION IN THE INDUSTRY
This section presents information on metal furniture
manufacturing operations, estimated VOC emissions, the
extent of current control and the likely alternatives which
may be used for controlling VOC emissions in Alabama.
4.3.1 Emissions and Current Controls
This section presents the estimated VOC emissions from
metal furniture manufacturing facilities in Alabama in 1977
and the current level of emission controls implemented in
the state. Exhibit 4-3, on the followinq paqe, shows the
total emissions from the 5 metal furniture manufacturing
facilities to be about 460 tons per year. These data were
obtained from the Alabama Air Pollution Commission and inter-
views with industry representatives. None of the manufacturers
listed has implemented hydrocarbon emissions control systems.
4.3.2 RACT Guidelines and Control Options
The emission limitations that can be achieved through
the application of Reasonably Available Control Technology
(RACT) for the metal furniture coating industry are presented
in Exhibit 4-4, on the following pages. This emission limit
is based on the use of low organic solvent coatings. It
can also be achieved with waterborne coatings and is approx-
imately equivalent (on the basis of solids applied) to the
use of an add-on control device that collects or destroys
about 80 percent of the solvent from a conventional high
organic solvent coating. In some cases, greater reductions
(up to 90 percent) can be achieved by installing new equip-
ment which uses powder or electrodeposited waterborne coat-
ings. A comparison of the various control options is pre-
sented in Exhibit 4-5, following Exhibit 4-4.
4.3.3 Selection of the Most Likely RACT Alternatives
The choice of application of control alternatives, for
the reduction of hydrocarbon emissions in existing facilities
for the surface coating of metal furniture, requires a line-
by-line evaluation. A number of factors must be considered
based on the individual characteristics of the coating line
to be controlled. The degree of economic dislocation is a
function of these factors.

-------
The first factor to be considered is whether the existing
equipment can be used by the substitution of a coating mater-
ial which will meet the RACT guideline. This alternative
would require the least capital expenditure and may minimize
production downtime.
If the existing equipment has to be modified, replaced
or expanded, factors to consider are the kind of changes
that have to made, the capital costs, the change in operating
costs, the length of time needed to make the changes, the
effect on the production rate, the operational problems that
will have to be handled and the effect on the quality of the
product.
Interviews with industry representatives in Alabama
indicated that plans for VOC controls have not yet been
formulated. Based on the experience in several states in
Region V, it is assumed that most manufacturers will use
their existing spraying equipment and modify it to handle
high solids or waterborne coatings. It was assumed that
existing dipping or flow coating equipment will be modified
to handle waterborne coating.

4.4 COST AND VOC REDUCTION BENEFIT EVALUATIONS FOR THE
MOST LIKELY RACT ALTERNATIVES
This section presents the cost for the most likely
control systems and associated VOC reduction benefit.
First the costs for the two types of model plants are
presented, which are then extrapolated to the statewide
industry.
4.4.1 Model Plant Costs and VOC Reduction Benefits
Two types of model plants, distinguished by production
output, were selected for the surface coating of metal furniture.
The first type included an electrostatic spraying line with
outputs of 3 million square feet and 4 8 million square feet
of surface area coated per year. The second type included
a dip coating line with outputs of 7 million square feet
and 22.5 million square feet of surface area coated per
year. Assuming a one-color single-coating line, the capital,
operation and maintenance costs for the model plant were
estimated. The cost of.pretreatment facilities, ovens and
plant building was excluded from total capital costs. The
annualized cost includes coating materials, utilities,
operation and maintenance labor^-, maintenance material*- and
capital charges (depreciation, interest, taxes, insurance
and administrative charges)General plant overhead cost
was excluded from the annualized cost. The estimated costs
for the model base plant and the incremental costs for the
most likely control options are presented in Exhibit 4-6
for the electrostatic spraying and in Exhibit 4-7 for dip
coating lines, on the following pages.
The assumptions for the cost estimates are discussed
in the RACT guidelines document (EPA-450/2-77-032). It
should be noted that the incremental costs, or savings, can
change significantly if the underlying assumptions are
changed. For example, if the base plant assumption of 25
percent solids coating was 30 percent solids coating, no
savings for conversion to higher solids (7 0 percent) would
result. Similarly, capital costs for conversion to water-
borne coating would increase dramatically, if significant
changes to the facility were needed, compared to the assump-
tion of cleaning and corrosion protection only of existing
dip tanks.
1. Maintenance material and labor charges were assumed to
be approximately equal to 4 percent of the capital cost
2. Capital charges were assumed to be equal to 18.68 percent.

4.4.2
Extrapolation of Control Costs to the Statewide
Industry
In Exhibit 4-8, on the following page, the costs for
meeting RACT guidelines for VOC emission control for surface
coating of metal furniture are extrapolated to the statewide
industry in Alabama.• The estimates are based on the following
assumptions and methods:
The 5 plants listed in Exhibit 4-3 were assumed
to require controls to comply with the RACT
guidelines.
The distribution of control options was based on
industry interviews, as well as Booz, Allen
estimates. Existing spray coating lines were
assumed to convert to high solids or waterborne
coatings and existing dip coating lines to water-
borne dip.
The capital cost of control for high solids and water-
borne spray and for waterborne dipcoating was estimated
by scaling up the model plants A-l and B-l costs by a
capacity factor calculated as follows. The capacity
factor was assumed to be one for the coating lines with
the model plants. For the coating lines with
greater emissions per line than those of the model
plant, the capacity factor per line vas determined
to be equal to:
(actual emissions/model plant emissions)^•6
The annual operating cost for high solids and waterborne
spray and waterborne dipcoating was assumed to be pro-
portional to the amount of emissions reduction
and was scaled ap from the model plant costs.
The data in Exhibit 4-8 show that the control of VOC
for surface coating of metal furniture to meet the RACT
guidelines in Alabama would require a statewide capital
investment of about $150,000 and a statewide net annualized
cost of about $26,000.

4.5 DIRECT ECONOMIC IMPACTS
This section presents the direct economic impacts of
implementing the RACT guidelines for surface coating of
metal furniture, on a statewide basis. The analysis includes
the availability of equipment and capital; feasibility of the
control technology; and impact on economic indicators, such
as value of shipments, unit price (assuming full cost pass-
through) , state economic variables and capital investment.
4.5.1 RACT Timing
RACT guidelines must be implemented statewide by December
31, 1982. This implies that surface coaters of metal furni-
ture must have made their process modifications and be
operating within the next four years. The timing require-
ments of the RACT guidelines impose several requirements on
metal furniture coaters:
Determine the appropriate emission control system.
Raise or allocate capital to purchase new equip-
ment or modify existing facilities.
Acquire the necessary equipment or coating material
for emission control.
Install new equipment or modify existing facilities
and test equipment and/or new materials to ensure
that the system complies with RACT and provides
acceptable coating quality.
The sections which follow discuss the feasibility and
the economic implications of implementing RACT guidelines
within the requirement timeframe.
4.5.2. Feasibility Issues
Technical and economic feasibility issues of imple-
menting the RACT guidelines are discussed in this section.
None of the metal furniture manufacturers in Alabama
interviewed during this study has implemented high solids
or water-based coatings to date. However, based on
4-11
-------
experience in other states, it is predicted that these manu-
facturers will convert to low solvent spray or waterborne
dip coatings in order to comply with RACT guidelines. These
coating materials may not be available in the desired quality
and the variety of colors required by the manufacturers. The
development of suitable coating materials in a variety of .
colors is the key to successful implementation of RACT in
the required time.
Unless major modifications to equipment are required,
the cost of conversion to high solids or waterborne coatings
is not likely to have a significant effect on the imple-
mentation of the RACT guidelines for surface coating of metal
furniture.
4.5.3 Comparison of Direct Cost With Selected Direct
Economic Indicators
The slight change in the annualized cost to the
coaters of metal furniture as a result of implementing RACT
guidelines is not expected to have a significant effect on
the economic situation in the metal furniture industry in
Alabama.
The major economic impact, in terms of cost outlay,
will be capital-related, rather than from increased annual
operating costs. The predicted capital costs are not signi-
ficant; however, they are based on the assumption that no
extensive modifications will be required. If extensive
modifications to existing plants are required, these costs may
become significant.
4-12
-------
4.6 SELECTED SECONDARY ECONOMIC IMPACTS
This section discusses the secondary impacts of imple-
menting RACT on employment, market structure, productivity,
and energy consumption.
Employment is expected to remain unchanged. Employ-
ment would be reduced if marginally profitable facilities
closed, but the present indication from the industry is that
no such closures are anticipated.
Productivity for those coaters who would be coating only
with high solids could be increased, because they will be
able to get more paint on per unit volume basis and reduce
paint application time.
Plants that convert to low solvent coatings will save
a small quantity of energy (less than 1,000 barrels per year)
due to the reduced drying time required. Those converting
to water-based coating will experience a small increase in energy
usage due to increased drying time.

16. ABSTRACT
The major objective of the contract effort was to determine the
direct economic impact of implementing RACT standards for selected
industrial categories in Alabama. The study is to be used primarily
to assist EPA and state decisions on achieving the emission limitations
of the RACT standards.
The economic impact was assessed for the following 2 RACT indus-
trial categories: surface coating of cans and metal furniture.
The scope of this project was to determine the costs and direct
impact of control to achieve RACT guideline limitations. Direct economic
costs and benefits from the implementation of RACT limitations were
identified and quantified while secondary impacts (social, energy,
employment, etc.) are addressed, they were not a major emphasis in the
study.
