                     CATC Information Bulletin
                           Summer 1999

A lot has happened since our last (Fall 1998) Information Bulletin.  Since we
tend to be optimistic, it is not as much as we hoped to accomplish, but we are
making substantial progress. Our overall level of activity (your access to CATC
services) is running a little ahead of last year.  CATC Web related services by
far dominate the way you access the CATC and we are working hard to keep our
Web sites current and relevant.

We do tend to use a lot of ACRONYMS, so we've included a section called
Short-Talk at the end of this bulletin. Just refer to this section if you need help
with an acronym.

Please share this Information Bulletin with others who  may have a need to
access CATC services. You can reach the CATC on the Web at , by E-Mail  at  , by phone at
(919) 541-0800, or by FAX at (919) 541-0242. The CATC includes the RBLC
and CICA, and works with SBAP. All of these programs are accessible from the
                                                                      NEW PRODUCTS AVAILABLE ON

Chapter 5 ("Fabric Filters") of the OAQPS Control Cost Manual (Fifth Edition,
1996) has been revised and posted on the CATC Web, in Acrobat (PDF) format.
This revision replaces the  chapter now  in the Manual, which was originally
finalized in late 1986. Like the old chapter, this revision contains descriptions,
sizing and cost-estimating  procedures, and  capital and annual costs for the
three major fabric filter ("baghouse") designs: shaker, reverse-air, and pulse-
jet.   In addition, the revised chapter addresses technologies not previously
covered, such as sonic cleaning and cartridge filters.  Material on the latter is
quite detailed, yet user-friendly.

The revised chapter also includes application and price information for three
new bag materials: Nextel®, P84®, and Ryton®. Prices for bags, bag cages,
baghouse compartments, baghouse add-ons (e.g., insulation), and all other
components  are in second quarter 1998 dollars.  Updated  prices  for  labor,
electricity, and  other annual cost components  are  also  included.   The
comprehensive example problem has been revised to incorporate the new
sizing and cost-estimating  procedures and data.   For answers to technical

CO$T-AIR Control Cost Spreadsheets (Second Edition)

The first edition of CO$T-AIR was released in early 1996.  Since then, over
2,500 copies of this package of spreadsheets have been distributed via the
OAQPS TIN. Like the original, this second edition consists of an introductory
WordPerfect file and 20 Lotus™ spreadsheets that make the calculation of capital
and annual costs for air pollution control devices and auxiliary equipment easy,
flexible, and  accurate.   The spreadsheets cover 12 control  devices (five
particulate matter, seven gaseous) and one auxiliary  (ductwork).  However,
these  revised spreadsheets   improve  upon  the  originals, sometimes
dramatically.   Errors  have been  corrected,  ambiguities removed,  and
enhancements made.  (For example,  the Carbon Adsorbers spreadsheet now
contains isotherm data for over 30 compounds, compared to 11 in the first
edition spreadsheet.)  Primarily based on design and cost procedures and data
in  the  OAQPS Control  Cost Manual (Fifth Edition,  1996), the CO$T-AIR
spreadsheets form a link between the Manual and the VAPCCI (Vatavuk Air
Pollution Control Cost Indexes), in that they allow for instantaneous escalation
of equipment costs.

1999  Small  Business  Ombudsman (SBO)/Small  Business Assistance
Program (SBAP) National Conference
The 1999 SBO/SBAP  National Conference was held on April 18 through April
21, 1999, in Tampa, Florida.   Conference presentation materials  that were
submitted by conference speakers are available  electronically, rather than  in
hard copy, at .
Although the RBLC is fully accessible via the WWW, all maintenance and
updates are performed on the old TTN BBS data base and then copied to the
Web.  Work to move these remaining functions to the Web has progressed
slowly. However, we still hope to have the data base fully transferred to the Web
environment in January 2000. The RBLC BBS would then be closed.  We would
also have to suspend  (at  least temporarily)  use of the RBLC Desktop and
Standalone Editor software programs because they will no longer be consistent
with the Web data base format  and  structure.  All data entry, NSR early
notification, and system updates and maintenance will be performed via the
RBLC Web. Once the new Web version is up and running, we will assess the
need for new RBLC Desktop and Standalone Editor software.  If you have an
opinion  about the need for the  RBLC Desktop and/or Standalone Editor
software, please let us know.

Fact Sheets & Technical  Bulletins

The CICA program has produced 20 Fact Sheets on various air pollution control
technologies and more are in the  works.  The Fact Sheets are actually 4-8
pages of succinct, substantive information that you may find  helpful when
evaluating air pollution control options. They also are an  excellent source of
information if you are not familiar with a technology and need a quick summary.
The Fact Sheets include the following topics: Name  of Technology; Type of
Technology; Applicable Pollutants; Achievable Emission Limits/Reductions;
Applicable Source Type; Emission Stream Characteristics; Emission Stream
Pretreatment  Requirements;  Cost  Information;  Theory  of  Operation;
Advantages/Pros;  Disadvantages/Cons;  Other  Considerations; and  Refer-
ences. They are available at both the CATC and CICA Web pages in PDF and
WordPerfect formats.  They are also available in Spanish.   (Continued)

HIGHLIGHTS (Continued)
Technical Bulletins are a little more comprehensive than Fact Sheets and are
about 10-20 pages long. Topics address the following questions: What is the
technology? Why is it important? How does it work?  What levels of emission
control/prevention  are achievable?  What  type of sources could use  this
technology? How much does it cost? What new developments are anticipated?
Lots of references are provided too. We believe you will find CATC Technical
Bulletins very useful and informative. They are available at both the CATC and
CICA Web pages in PDF and WordPerfect formats. They are also available in
