provides information needed to assess
emissions control options for volatile or-
ganic compounds (VOC) and hazardous
air pollutants (HAPs) from this industry.
This CTC document provides infor-
mation on leather tanning and finishing
processes, potential emissions from
these processes, and emission control
options. The primary sources of VOC &
HAPs are: leather finishing opera-
tions; waterproofing operations; solvent
degreasing operations; and miscella-
neous fugitive sources. Table 1 lists air
pollutants emitted from these sources.
These pollutants were identified in the
Toxic Release Inventory (TRI) for the
years 1987-1990, and also from data
obtained from operating facilities.

It's been very busy! The Small Business Assistance Pro-
gram (SBAP) has exploded. CTC accesses lead by BBS
activity (especially the RACT/BACT/LAER Clearinghouse
(RBLC)) have continued at the high rate that began in October
of 1992. That's when the RBLC moved to the OAQPS
Technology Transfer Network BBS. We have already far
exceeded the 15,000 accesses to CTC services experienced
in all of FY92. In fact, at the current rate of usage, accesses
to CTC services in FY93 will almost double FY92 levels.
Thanks for your continuing vote of confidence. I just hope we
can keep up with the pace and continue to provide you with
quality services with the resources at hand. We'll do our best
for you!
As you may know, CTC project funds to support your
request for case specific assistance and general technical
guidance were cut substantially in FY93. Virtually all FY93
funds were expended as of June. New funding won't be
available until late October. However, we are still looking for
good projects. The tighter budget increases competition for
this limited resource, so it's important to get your request to us
as soon as possible. We would love to have a host of projects
approved and ready to go when new funds become available.
In fact, depending on demand and funds left over from other
programs in FY93, we may be able to expand this assistance
effort slightly in FY94 (that begins October 1 for us). So don't
wait! Get your request in now and go to the front of the line!
Be sure and check out new software tools available only on
the CTC BBS. This includes SAGE, a guide to selecting more
environmentally friendly solvents, and an improved version of
HAP-PRO. See the articles in this edition of the CTC NEWS
for more information.
The CTC gets numerous requestfor information on sched-
uling of CTGs and MACT standards and we've had sugges-
tions to include that kind of information on the CTC BBS or in
the CTC NEWS. We think that's a great idea that could save
us all a lot of phone calls and time. There has been some
reluctance here at EPA because schedules are really best
estimates that tend to change, and publishing scheduling

Five existing State and local regula-
tions affecting the leather tanning and
finishing industry have been identified.
The States of New Jersey, New York,
and Massachusetts limit the VOC con-
tent of the finishing material. The State
of Wisconsin limits VOC emissions by
the square footage of leather finished.
The State of Illinois incorporates compo-
nents of
both types of
rules. Table

The source reduction techniques
available to leather finishing operations
and the associated emission reductions
tend to be very site-specific. The only
known abatement device currently em-
ployed within the domestic leatherfinish-
ing industry is regenerative thermal in-
cineration. Presently two facilities use
this control technology. They are
Mercersburg Tanning, Mercersburg, PA
and Seton Company, Saxton, PA.
Other efforts to reduce emissions
from leatherfinishing can be categorized
by: a) use of lower VOC or water-based
coatings; b) improved transfer efficiency
of the coatings application process; and
c) improved housekeeping practices and
employee training. Eagle Leather com-
pany, Grand Heaven, Ml, is the only
automotive leather upholstery manufac-
turer in North America to convert to wa-

SOLVENT
ALTERNATIVES GUIDE
(SAGE):
A New Tool to
Assist in Selection of
Surface Cleaning
Alternatives
By Chuck Darvin,
CTC/AEERL
The January 1,1995, Montreal Pro-
tocol deadline for elimination of produc-
tion of certain chlorofluorocarbons
(CFCs), including CFC-113 ( 1,1,2-
trichloro-1,2,2-trifluoroethane) and
methyl chloroform (1,1,1-
trichloroethane), is rapidly approaching.
One of the major applications of these
compounds is in metal surface cleaning
and degreasing. They are used over a
broad range of industries and cleaning
applications, ranging from precision
cleaning of mechanical and electronic
parts to general cleaning and paint re-
moval. Businesses and government
agencies, faced with replacing CFC sol-
vent cleaning systems with which they
have been comfortable for many years,
are frantically looking for replacement
alternatives. In the past they have relied
upon information provided by vendors to
define solvent replacements, which
were usually CFC systems. With the
advent of the Montreal Protocol, how-
ever, all has changed. Users must now
become more conscious of their surface
cleaning requirements and knowledge-
able of the chemistries and processes
involved in surface cleaning.
The Solvent Alternatives Guide
(SAGE) is a continuing program con-
ducted by the EPA's Air and Energy
Engineering Research Laboratory. It is a
PC-based system that provides general
and detailed information on solvent re-
placement chemistries and processes.
It is designed to serve as an electronic
handbook and expert system that identi-
fiesthe most viable alternative for agiven
cleaning scenario. SAGE can be used
by individuals ranging from shop super-

visors to regulatory agency personnel
and does not require a detailed knowl-
edge of process chemistry or mechan-
ics. It provides the user with a list of
viable cleaning alternatives. It highlights
the requirements for implementing the
cleaning option and eliminates most of
the preliminary investigation required to
select a substitute solvent system.
Aware of the requirements and limita-
tions of the viable alternatives provided
by SAGE, the user will then be in a
position to complete final process evalu-
ations to ensure that the alternative will
satisfy the specific production require-
ments of the operation.
The first version was released in
April 1993 and placed on the CTC bulle-
tin board for downloading. Version 1.0 is
considered a B ETA test version for both
use and comment back to the Control
Technology Center (CTC) by users. Vi-
able comments will be incorporated into
subsequent versions. Additional data
and solvent information are being added
to the system as they become available
from studies and research demonstra-
tion programs conducted by the EPA
laboratory. The next version, 1.1, will be
available in July 1993.
The SAGE system begins by asking
questions that someone responsible for
developing an alternative cleaning pro-
cess would investigate before selecting
an alternative cleaning system. Ex-
ample questions include type of part,
material, shape and size of part, type of
contaminant, desired cleanliness, and
processes before and after cleaning.
Each question permits the system to
evaluate process requirements,
economics, and material re-
quirementstoselectthemost co2asc
viable option(s) for the de-
fined manufacturing process. Based on
the answers to the questions, SAGE
provides responses that define a limited
number of cleaning process chemistries
and mechanical processes. It defines
alternatives only in generic terms, and
does not providetrade or vendor names.
It will provide a detailed report complete
with references, case studies, regulatory
impacts, and safety and equipment re-
quirements. In later versions it is antici-
pated that added economic projection
and process design capabilities will be
incorporated into the system.
All that is required to gain access to
SAGE is a PC with a modem. SAGE is
currently available and can be down-
loaded through the CTC BBS. Further
information can be obtained by calling
the CTC HOTLINE.

The CTC recently published report
EPA-600/R-93-044 (NTIS PB93-
172914), entitled "Characterization of
Emissions from the Simulated Open-
Burning of Non-Metallic Automobile
Shredder Residue." In this project, ex-
periments were performed to examine
emissions of organics, particulate, and
metals from a simulated open burn of
shredderfluff. The project was prompted
by a request from the State of Virginia,
which was interested in emissions from
af luff fire that occurred at an automobile
NOasN
Volatile Organics
(CO), nitric oxide (NO), oxygen (O2), and
unburned hydrocarbons (THC), were
monitored continuously. Volatile and
semi-volatile organics characterized in-
cluded mono- and poly-aromatic hydro-
carbons, substituted alkanes and alk-
enes, aldehydes, nitriles, phenols, chlo-
rinated aromatics, heterocycles, and
polychlorinated dibenzodioxins and
furans. Of the 11 metal aerosols charac-
terized, cadmium, copper, lead, andzinc
were found in significant quantities. The
emission characterizations performed
indicated that substantial quantities of air
pollutants are emitted. For the organic
pollutants alone, the emission of more
than 200 g/kg of fluff combusted was
observed. Figure 1 illustratesthe results
from a mass balance performed on the
measured air emissions from the fluff

SBAP Bulletin Board
System (BBS) -
INPUT DA TA NEEDED!
The SBAP BBS is scheduled to be
available in the Fall of 1 993. This system
will be the primary mechanismfor States
and EPA to share information on small
business activities and available materi-
als. A number of State SBAPs have
already indicated that they have several
items to share with their colleagues.
We would like to have as much infor-
mation as possible on the SBAP BBS
when it comes on-line. To do this, we
need a little help from the State SBAPs.
If you have any items you wish to have
placed on the SBAP BBS, please send
us the following information:
Subject of materials (specific industry,
general guidance, etc.)
Type of information available (bro-
chure, report, video, opportunity for a
coordinated effort, etc.)
Short description of materials/project
Status of project (early planning, under
development, available for distribution,
etc.)
Contact, agency name, and telephone
number for more information.
We would also like to include read-
able/downloadable files on the SBAP
BBS. If you can provide af loppy disk with
the materials you wish to share in an
ASCII text file, we can make it available
directly on the SBAP BBS. This would
save us all a number of phone calls and
questions, as well as provide detailed
information to those who need it as
quickly as possible. Once the SBAP
BBS is well established, new materials
for addition to the system will be submit-
ted directly through the BBS itself.
Help us get the new SBAP BBS off
to a quick and useful start! Send your

EMISSIONS
MEASUREMENT AND
EVALUATION:
BRUCE HARRIS
By Kim Thompson
Acurex Environmental
Bruce Harris, currently part of EPA's
Air and Energy Engineering Research
Laboratory, started work with the Na-
tional Air Pollution Control Administra-
tion after graduating from the University
of Florida in 1968. The National Air
Pollution Control Administration soon
joined with other organizations to form
the U.S. Environmental Protection
Agency (EPA). During his 25-year ten-
ure at EPA, Bruce has gained and
shared experience and knowledge in
five branches. As a result of his varied
background with the EPA, Bruce is a
valuable resource to the Control Tech-
nology Center. His knowledge of air
toxics and paniculate control measure-
ment, and radon control has been very
useful in responding to requests from
state, local, and regional government
offices.
Earning his bachelor's of science
degree in mechanical engineering from
the University of Florida in 1967, and
then his master's in Environmental Engi-
neering from the University of Florida in
1968, prepared Bruce for his long career
with the EPA, which began in Cincinnati,
Ohio, as a Public Health Service Engi-
neer Officer. Most of his time was de-
voted to measurement technology ior
particulate matter and establishing a
particle sizing laboratory to support in-
house and field
activities for the
Control Technol-
ogy Program.
Bruce was
one of the first
engineers to be
assigned to
EPA's Environ-
mental Research
Center at Re-
search Triangle
Park in North
Carolina. After
relocating to the
Triangle area,
Bruce continued
his work in measurement technology,
but carried it further by becoming active
in international symposia and conduct-
ing international research programs with
the former USSR.
Bruce's expertise in measurement
technology led him into the study of the
coal used in the People's Republic of
China. This project is investigating the
link between lung cancer and the resi-
dential, unvented burning of coal for
heat. As a result of his work with coal in
China Bruce received the Level 1 Scien-
tific and Technological Achievement
Award in 1987 for Establishing an Etio-
logic Link Between Domestic Smoky
Coal Burning and Lung Cancer in Xuan
Wei, Yunan, China. His continuing work
in China included a cooperative field
measurement project that involved de-
veloping special measurement meth-
ods.
Most recently, he has been heavily
involved in radon mitigation studies. He
was also instrumental in the develop-
ment of diagnostic methods for the de-
sign, installation, and evaluation of ra-
don mitigation systems. Training
courses were conducted for school per-
sonnel and mitigators so thatthese mea-
surementscould be taken in schools and
large buildings.
Currently, Bruce is working on de-
veloping diesel fuel emission factors
emitted by cars and trucks. There is
reason to believe that the information
provided to established emissions mod-
els may be misleading regarding how
much nitrogen Oxides (NOx) is being
emitted. Studies in
this area indicate
that many factors
may affect the lev-
els of pollutants re-
leased from cars
and trucks; e.g.,
drivers' driving
habits, heavy traf-
fic, high speeds,
and acceleration
patterns.
Bruce's mar-
riage of 25 years
parallels his 25
years with EPA,
which he and his
wife celebrated recently with an anniver-
sary cruise to the Bahamashis mar-
riage, that is! They are an active couple
with one child in high school and two in
college. Bruce also stays busy as a
member of the Knights of Columbus on
the church and state levels. He is very
deserving of his two awards, a PHS
Citation and a PHS Meritorious Service
Award.
EPA's Control Technology Center
has been very fortunate to count Bruce
as one of its experts in several fields.
Because of his diverse background, he is
able to assist many callers, and he can
also direct callers to other specialized
experts. By answering questions and
concerns from state, local, and regional
government agencies, Bruce is able to
keep current with projects that he is no
longer directly associated with, but still
maintains personal and professional in-
terest in.

can make your printout short, easy to print, and well worth the
paper it's printed on. The wrong choice can make your printout
long, hardto print, and generally awaste of the paper it's printed
on. Hopefully, the information below will enable you to make
this difficult (and truly world shattering decision) correctly!
A list of download formats available within the RBLC
Information System (BUS)
is presented in Figure 1.

CARBON
REACTIVATION ACT
DOCUMENT
By Bob Blaszczak,
CTC/OAQPS
Carbon adsorption is one of the most
commonly used organic air emission
control technologies for hazardous air
pollutants (HAPs) and/or volatile organic
compounds (VOC). It is also used to
treat potable water. As carbon is used
and regenerated over time, it loses a
significant portion of its reactivity. Atthis
point it must be replaced. The spent
carbon is then disposed or reactivated.
The reactivation process involves ex-
posing the spent carbon to high tempera-
tures in a separate processing unit or
furnace to remove organic contami-
nants.
The Emission Standards Division,
OAQPS, recently released "Alternative
Control Technology Document - Carbon
Reactivation Processes" (EPA-453/R-
92-019). This document describes this
industry, processes used to reactivate
the carbon, and potential emissions.
Spent carbon may be consider a hazard-
ous waste under RCRA if it is a listed
hazardous waste, was used to treat a
listed hazardous waste ("derived from"
rule), or exhibits one or more of the
RCRA hazardous waste characteristics.
Emissions may include organics (HAPs/
VOC), acid gasses, particulate matter,
and metals. Control systems usually
include a thermal afterburner and, if ha-
logenated organics are present, a
packed tower to remove acid gasses.
Other control system options include
spray towers; dry, venturi, or impinge-
ment scrubbers; cyclones; and bag-
house filters.
The ACT discusses all of these con-
trol options. It also provides environ-
mental impacts and costs analyses for
two model emission control systems for
small, medium and large carbon reacti-
vation plants. Call the CTC HOTLINE or

NEW PROJECTS
UNDERWAY
By Bob Blaszczak
CTC/OAQPS
The CTC has initiated several
projects in the lastfew months and would
appreciate your help and input. If you
have any information or insight that
might help in these efforts, pleasecallthe
CTC HOTLINE.
PAINT SPRAY GUN CLEANING: This
project requested by the Sacramento
Metropolitan AQMD will evaluate poten-
tial VOC emissions from various spray
gun cleaning equipment now on the
market. Although intended to minimize
VOC emissions compared to conven-
tional practices, differences in design
and operation among the various de-
vices may result in different levels of
effectiveness. The project should be
complete in March 1994.
STYRENE CONTROL TECHNOL-
OGY: As a follow-up to the CTC report
on fiberglass boat manufacturing, the
CTC has been evaluating new control
technology designed to treat styrene
emissions. One report evaluating the
Polyade (TM) polymer adsorption sys-
tem will be available in earlyfall. Another
project to evaluate the Chemtact (TM)
scrubber (QUAD Environmental) should
be complete late this year.
EMISSIONS FROM PAINT MIXING:
After considerable time, discussion, and
deliberation, the CTC has initiated a re-
search project to determine emission
factor information for paint mixing pro-
cesses. The project was originally pro-
posed bythe Bay AreaAQMD. Asched-
ule f or this project is still under develop-
ment.
HF FROM FERTILIZER PLANT LA-
GOONS: This project requested by the
Florida DER will determine potential
emissions of hydrogen fluoride from la-
goons/impoundments that treat scrub-
berwastewaterfrom phosphate fertilizer
plants. We hope to have results late this
fall.
OIL SUPPRESSION OF PM AT GRAIN
ELEVATORS: The CTC has joined in a
coordinated effort with the Emission
Measurement Technical Information
Center (EMTIC), Clearinghouse for In-
ventory and emission Factor Information
(CHIEF), Nebraska DEQ and private
vendors to address the effectiveness of
soybean/vegetable oil suppression sys-
tems in controlling particulate emissions
fromgrain elevators. Pending resolution
of source testing issues, we hope to have
a report in the fall.
GOING BEYOND CTG RACT: The
Lake Michigan Air Directors have re-
quested the CTC to list and rank State
and Local agency RACT rules that have
gone beyond CTG requirements. This
project is scheduledto begin soon.
