CTC Co-Chair, OAQPS

     Happy New Year!  This is my fifth and busiest year as CTC Co-Chair.  It
seemed to pass by me at WARP nine (for you non-trekies that s about 729
times the speed of light).  I m not sure if the cause is my advancing years,
the ever growing level of CTC activity, the need to do more with less, or a
combination of these and other related factors.  I do know that you have kept
us very busy and there is still a lot to be done.
     FY93 (October  92 through September  93) was a very active year.  CTC
services were accessed 30,000 times compared to 8,000 in FY91 and 15,000 in
FY92.  This explosion of activity is primarily the result of expanded user
access to CTC services through our electronic bulletin board systems (BBSs).
CTC BBS activity doubled in FY93 while RACT/BACT/LAER Clearinghouse (RBLC)
Information System (BLIS) BBS activity increased by almost an order of
magnitude.  We are still awaiting the impact of the Federal Small Business
Assistance Program (SBAP), another CTC activity, which is expected to take
off in FY94 and significantly increase the number of CTC accesses.  See the
graphic on page 2 (Figure 1) for more dramatic details on CTC activity.
     Page 5 of this edition is the annual CTC document ordering form.  The list
includes only those documents completed within the last 2 years.  If you would
like a complete list of CTC products, check reference 48 on the ordering form. 
To order, just cut out the form, check the documents you need, enter your
mailing address, fold in half and staple or tape it closed, and apply first
class postage. CTC products are available to government agencies free of
charge.  Others should order documents through the National Technical
Information Service (NTIS) by calling (703) 487-4650 and using the NTIS
document number (begins with PB) on the ordering form.  Please save some
trees and order only those documents you need!
     Be sure to check the schedule for new rules and CTGs.  As you recall,
the CTC NEWS began this feature in the last edition.  A number of proposals
have been issued since then and other changes have been made to accommodate
Federal budget cuts.  I hope you find this scheduling information useful.
     Enjoy the NEWS and have a healthy and prosperous new year!

PAINT SPRAY BOOTH CLEANING

By Bob Blaszczak
CTC Co-chair/OAQPS and
Mohamed Serageldin
CPB/ESD/OAQPS

     The CTC report  Automobile Assembly Plant Spray Booth Cleaning Emission
Reduction Technology Review  is scheduled for release in March 1994.  This CTC
study, requested by the Michigan DNR, identifies reasonable alternatives for
minimizing VOC emissions.  This includes organic HAPs from cleaning paint
residue in automobile assembly plant paint spray booths.  The use of
solvents to clean spray booths in an automobile assembly plant can result
in evaporative emissions of hundreds of tons of VOC each year
(See Figure 1).  This CTC report presents information from 15 plants operated
by 8 different auto  manufacturing companies.  It documents the use of
alternative cleaning practices and the resultant reduction in VOC emissions.
It also documents and explains procedures for accurately estimating
evaporative emissions from the use of solvents for cleaning spray booths.
     Only a fraction of the paint material sprayed in a booth lands on the
automobile parts being coated.  A significant portion collects on the walls,
windows, robots, fixtures, floor grates, and other components of the booth.
The amount of coating deposited on components of a booth is inversely
proportional to the paint transfer efficiency.  The latter parameter provides
an indicator of the portion of paint used which lands on the surface area of
the coated parts.
     The paint overspray creates a sticky residue on booth surfaces which
must be removed.  Traditionally, the residue has been removed using organic
solvents.  There were reports, however, that some plants had successfully
implemented alternative cleaning procedures which significantly reduced
solvent usage and hence emissions.  Cleaning methods considered in this
study included: mechanical methods (scraping, mechanical scrubbers, water
blasting, etc.,); masking agents (tacky coatings, peelable coatings,
petroleum jelly, etc.); covers (tar paper, kraft paper, cardboard, plastic
sheeting, aluminum foil, etc.); water-based or low VOC cleaners; and changes
in work practices (wiping instead of spraying solvent, smaller tips on
solvent spray guns, reducing frequency of cleaning, etc.).  Emissions were
estimated by material balance calculations using the unit operation system
(UOS) concept developed by Mohamed Serageldin.  In this case, the UOS
defines the ensemble around which a material balance  for cleaing can
be performed.  It includes all possible points/sources leading to evaporative
emission losses associated with cleaning.  (See Figure 2.)
     Since at least one plant cleaned each type of spray component (except
spray equipment tips and some robot surfaces) without using solvent,
significant potential for VOC reductions exists.  The potential for
reductions depends on booth design, the type of paint, and the article
being painted, as well as the cleaning practices.  Potential reductions for
a plant can range from a few tons to nearly 1,000 tons per year.  Typically,
reductions achieved by specific alternatives are less than 20 tons/yr, but
can range up to nearly 200 tons/yr.  Elimination of solvent spraying as a
cleaning practice holds the greatest potential for emission reductions.  The
UOS provided a means to systematically calculate emissions, and to determine
specific normalized emissions, resulting in the grouping of most plants into
three emission categories (low, medium, and high).  A UOS also defines an
emission boundary for comparing pollution prevention alternatives.
     To order a copy of this report call the CTC HOTLINE, or check reference
number 96 under VOC Source Categories on the enclosed CTC Resources form
and mail it to the CTC.

SAGE UPDATE

By Charles H. Darvin
CTC Co-Chair, AEERL

     There is good news for those of you who have received and used
the Solvent Alternatives Guide, SAGE, the computerized surface
cleaning process selection system.  The next version of SAGE is
scheduled for completion in early February 1994.  
     SAGE Versions 1.0 and 1.1 were Beta test versions for review
and comment on the concept and content of the system.  The response
from the hundreds of users who acquired the system, either through
the CTC Bulletin Board or on disk, has been overwhelmingly
favorable and complimentary.  In fact, we received many replies
with suggestions for further expansion of the system s capability. 
Many of your recommendations have been incorporated into SAGE;
thus, I believe that you will be even more satisfied with SAGE
Version 2.0.  
     The new version will be an even more powerful decision tool,
with all sections expanded to provide more data to support the
system s  recommendations.  Version 2.0 will have a limited
facility and process design capability to give a graphical
presentation of the cleaning steps required for the recommended
surface cleaning alternative.  A checklist will be incorporated
into the summary to assist process design engineers in identifying
the various technical and compliance issues that must be
investigated prior to their final selection of a cleaning
alternative.   The new version will include cleaning of
non-metallic substrates such as plastics and fiberglass, electronic
component cleaning, and paint stripping.  Most importantly, it will
include additional case studies to support the recommendations
generated by SAGE.  
     Unfortunately, as a penalty of success, the CTC will no longer
be able to send out disks of SAGE version 2.0.  The overwhelming
number of requests has made it impossible for the CTC staff to mail
out SAGE disks in the future.  However, you can continue to
download the latest version of the system from the CTC Bulletin
Board.  The Bulletin Board number is (919) 541-5742, and it can be
accessed 24 hours a day, 7 days a week.  The newer vrsion will also
be supplied to the National Technical Information Service, NTIS,
where a disk may be acquired for a nominal fee.  The NTIS phone
number is (703) 487-4650.  If there are further questions
concerning SAGE, please contact the CTC HOTLINE at (919) 541-0800.

SMALL BUSINESS UPDATE

Deborah Elmore, 
Federal SBAP Coordinator, CTC/OAQPS

*SBAP Technical Assistance Conference

     The First Annual National Small Business Technical Assistance
Conference was held on January 12-14, 1994, in Raleigh, North
Carolina.  With over 100 attendees, representing more than 40 State
and local small business assistance programs, the conference was a
great success.  Everyone came away with new ideas and information
to use in assisting small businesses (as well as each other!). 
Thanks to all who participated, and hope to see you again next
year.  




*SBAP Bulletin Board System (BBS)

     The SBAP BBS is now scheduled to be available in the late
Spring of 1994.  Several State SBAPs have already indicated that
they have items to share with their colleagues.  We would like to
have as much information as possible on the SBAP BBS when it comes
on-line.  To do this, we need a little help from the State and
local SBAPs.  If you have any items you wish to have placed on the
SBAP BBS, please let us know as soon as possible. Remember, even if
your  materials  can not be downloaded directly from the SBAP BBS,
we can still provide information on what it is, and how to get a
copy.  Help us get the new SBAP BBS off to a quick and useful
start!  For information, contact:

DOWNLOADING FILES FROM THE BLIS BBS


By Jo Ann Kerrick
VGYAN Inc.

     Usually when we talk about BLIS, we re referring to the
RACT/BACT/LAER Clearinghouse (RBLC) Information System, the data
base of control technology determinations.  BLIS also refers to the
RBLC s bulletin board system (BBS) on the Technology Transfer
Network (TTN).  In addition to the BLIS data base, the BLIS BBS
gives you access to current alerts, private Email, public messages,
and documents and other technical information pertaining to control
technology.
     Documents and technical information are available in the
DOCUMENTS/ SOFTWARE section of the BLIS BBS Main menu.  Documents
include the RBLC s annual compilation of control technology
determinations, the BLIS User s Manual, and the BLIS Informational
Flyer.  Technical information includes a variety of tables,
instructions, and other notes related to using the BLIS data base. 
For published documents, you may either order a hard copy of the
document from the BBS or NTIS, as appropriate, or download a
document file and print it locally.  Technical information is, in
general, only available via downloading from the BBS.
     If you can access the BBS, you have everything you need to
download files: a PC, a modem, a connection, and communication
software.  The letter D initiates downloading from the BLIS BBS. 
Downloading files is a standard BBS procedure.  In fact, you may
have used it already on other boards.  When you select downloading,
the BBS displays a list of files that may be downloaded and a
command prompt line (Fig. 1, page 3).  The list includes the name
of each file, its size in bytes, the date the file was last
updated, and a brief description of its contents.  To download a
particular file, enter  D  (again, this time at the command prompt
line), followed by a space and the file name.  The download
procedure has clear prompts, but, if you need it, help downloading
is available from the System Utilities section of the TTN Top menu.
     As you review the list of files available for downloading, pay
particular attention to te file name and its size.  On the BBS,
file names include standard file extensions (the characters after
the period) that indicate the type of the file.  Two frequently
used extensions are TXT (for text files that can be displayed on
the screen) and ZIP (for compressed files that must be dearchived
before use).  TXT files may be viewed on the screen by typing  P 1
file.ext .  For ZIP files, get a copy of the dearchiver from the
Archivers/Dearchivers section of System Utilities.  File size gives
you a rough idea of the time required to download the file.  With
a 9.6 Kbps modem, files of 50,000 bytes or less can be downloaded
in a few minutes.  Files of 250,000 bytes or more require 10 or
more minutes.  The BBS does not restrict the number and sizes of
files you can download;  however, you may wish to plan to download
large files when you do not need your PC for another activity.
     Documents and technical information available for downloading
from the BLIS BBS fall into two general categories.  First,
published documents include text and tables from the current year s
compilation of control technology determinations.  Because of the
large amount of information in the 1993 compilation, the document
has been divided into sections and each section has been zipped. 
If you are familiar with the format of the annual compilation,
download the sections that you need.  If you are not sure, review
the general information file RBLCINFO.TXT for an explanation of the
contents of the different sections.  The BLIS User s Manual and
Informational Flyer may also be downloaded.  Choose either a
WordPerfect 5.1 format or a flat ASCII text file.  Remember, you
can also order a hard copy of any published document from the BBS
or NTIS, as appropriate.
     The second category of files available for downloading
includes technical information related to using the BLIS data base. 
These are miscellaneous files that have been collected by the RBLC
staff to help you use BLIS more effectively.  This information is
only available via downloading from the BBS.  The precise list of
files changes.  Some of the files you are likely to find include
the following:
       Instructions for filling out the form for hard copy submittals
to the RBLC Tables of process type codes and SIC codes, both required
inputs for BLIS Text from past newsletters.  Source codes were used in
the data base prior to 1992.
     When you have a question about BLIS, browse through the list
of files available for downloading.  Downloading gives you the
information you need, when you need it, so you can continue
working.  With downloading, there s no need to wait weeks for
delivery of a hard copy of a document.  


                       BLIS Software and Other Items    
                                                        
 The following systems may be downloaded from the compressed files. 
They include executables and some documentation.  Programs and
instructions for dearchiving compressed files can be found via
<S>ystems Utilities from the Top menu under
<A>rchivers/dearchivers.  Other Items are in .TXT format and may be
printed to the screen or downloaded.

DOWNLOADING - WHAT TO DO NEXT!

By Lyndon S. Cox
Senior Environmental Employee

     I have received a lot of calls which have addressed the matter
of downloading.  The problem usually starts where the Bulletin
Board System (BBS) stops.  That is, when the file is identified,
the protocol is identified, and the computer is waiting for a start
signal.  Some people do not know what to do next.
     First, you need to know that, when giving commands to the BBS,
you give input to your computer as though it were a terminal.  This
is referred to as terminal mode.  What you type is really giving
commands to the BBS computer, and not to your computer.  You have
to transfer from terminal mode into command mode to give
instructions to your own computer.  You move from terminal mode to
command mode in various ways, depending on the communications
software you are using.
     When using Crosstalk XVI software, the usual means of reaching
command mode is to press  ESCape  or  HOME  (or  SHIFT-HOME  if
emulating a DEC terminal).  Although these are the default
settings, they can be changed.  Then you enter  RX drivepath
filename.    RX  is the command to receive the file by XMODEM.  You
would use  RK  if you had given Kermit as a protocol to the BBS. 
 Drivepath  is the drive and the directory (other than XTALK
directory) where you want to send the file.   Filename  is the name
of the file, including the extension.  Entering that command starts
the transmission.
     Crosstalk Communicator on the other hand uses ALT-P to reach
a window which selects between  SEND  and  RECEIVE.   After you
enter  RECEIVE,  another window asks for filename and drivepath. 
After filling these in, you must  ENTER  to start the download.
     In Windows Terminal, you first must select  XMODEM  or
 Kermit  under  Settings  and  Binary Transfers ; it is not
prompted for during the download process.  Then you select  Receive
Binary File.    A Binary file is an operating program, and a Text
file is an American Standards Committee for Information Interchange
(ASCII) file.  You are cued to select the drivepath.  When you
enter this and click on the  OK  button, the transmssion starts.
     Procomm uses an easier instruction set.  First you press PgDn
to indicate that you want to receive a file.  Then you choose the
protocol.  Then you enter the drivepath and filename when (or if)
prompted.
     If you use TELIX, you press ALT-R to receive a file, then you
are cued to give the filename and protocol.  Entering these starts
the transmission. 
     With QuickLink2Fax, you select  Receive a File,  then you are
cued to enter the filename and select the transmission protocol. 
The transmission starts automatically when you  ENTER  this
information.
     By now you may have seen the pattern.  Your communications
software determines the details of how you reply, but it is always
reach command mode, and enter the drivepath,  filename, and
downloading protocol (not necessarily in that order) plus whatever
else you are cued for.  When in doubt about your situation, read
the User s Manual for the communication software.  Look under
 Receive a File. 
     I have limited the choice of protocols to XMODEM or Kermit
because those are the only protocols offered in some cases.  XMODEM
is limited to transfer of one filename at a time.  It is error
detecting and does not continue when it finds an error, but
requires retransmission until no error is detected.  ZMODEM is a
standard that is also error detecting but permits multiple file
transfers, and is best for most situations.
     Kermit is another story altogether.  It is best used when you
use INTERNET, ethernet, VAX, and other non-PC hardware.  If you are
accessing the BBS via INTERNET, it is essential to use Kermit. 
File transfers via INTERNET using XMODEM are chancy, while YMODEM
and ZMODEM are sure to fail.
     If you find out what your situation calls for and follow these
tips, your next download should go smoothly.  If it does not, call
the Technology Transfer Network Helpline at (919) 541-5384 between
11:00 AM and 5:00 PM (EST) to find out what you need to do
differently.
