     In July 1989, Volume 1, No.1, of the CTC NEWS was issued.  Eight years
and 33 editions later, it's time to say goodby to the CTC NEWS.  It also is
time to say goodbye to the CTC as we now know it, and welcome the Clean Air
Technology Center (CATC).
     Although at times it s hard for an old-timer like me to adapt to change,
I am actually very enthusiastic about this change.  The CATC s mission and
goals are now consistent with management's vision, its budget, and current
information transfer realities.  The CATC also recognizes the wide variety
of information sources available to you, our customers, and will strive
to complement these sources.  The change allows me to focus my efforts on
making long over-due improvements to the RACT/BACT/LAER Clearinghouse (RBLC)
which now will become the backbone for compiling technical information on air
pollution prevention and control under CATC.  This is actually a very exciting
time.  Decisions have been made.  Our mission is clear.  Marching orders have
been issued.  Its time to get on with the job at hand.
     The one major downside of this change is that our CTC co-sponsor, the Air
Pollution Prevention and Control Division (APPCD), National Risk Management
Research Laboratory, Office of Research and Development (ORD), will not be a
CATC sponsor.  Although the APPCD has graciously indicated its willingness to
help respond to technical questions from you, if appropriate, as of October 1,
1997, the APPCD will no longer provide administrative, financial and
management support to CATC as it did with the CTC.  The unique cooperative
venture entered into by the ORD and the Office of Air and Radiation over  10
years ago and that became the CTC was a remarkable and extremely positive
experience that exceeded every expectation. We will sincerely miss Charlotte
Bercegeay, APPCD CTC Co-Chair, Lyn Cox, the CTC HOTLINE s premier senior
engineer, an all the APPCD staff who have supported the CTC and its work
through the years.  Thanks for 10 productive years of cooperation and hard
work.
     Last year, fiscal year (FY) 1996, was absolutely weird.  For the first
time since its inception, the CTC s numbers were down (about 25%).  However,
with government furloughs and unsure budgets, I guess that was not totally
unexpected.  What is totally unexpected is the rebound experienced in FY97.
The CTC s numbers are up over 150% over the same period last year and still
growing!  In fact, the CTC will close out with an all time record high in
the number of accesses to its services.  What an awesome finale!  Most of
this rebound is in World Wide Web (WWW)  accesses.  If you think we inflated
the figures by counting "hits" on CTC/RBLC WWW pages, think again!  We
actually base our figures for electronic access on the historical ratio of the
number of users accessing our bulletin board systems (BBS) to the number of
products actually downloaded (i.e., we only count downloads and multiply that
by the historic ratio of CTC clients accessing the CTC electronically to the
number of products they download).  The result is a much smaller number than
WWW page "hits." When we tally the final stats for the CTC in FY97, total
accesses will easily exceed 50,000!

Control Clean Air Technology Center (CATC)
By Bob Blaszczak, CATC/OAQPS

     It s time to make a change.  It s time to say goodbye to the CTC and
welcome the CATC. It may not be revolutionary but most definitely it is
evolutionary.  The CTC and the RBLC (RACT/BACT/LAER Clearinghouse) have been
reengineered and reconstruction is underway.  It was bound to happen.  Change
is inevitable.  If we don t adapt to the world around us, we will not succeed.
     As the offspring of the CTC and RBLC, CATC retains the same basic
characteristics of both of these programs but has adapted to the new realities
of cyberspace information transfer and fiscal restraint.  The good news is
that we will still be here to provide technical assistance to you, our valued
customer.  The bad news is that some of the services that the departing CTC
offered will be curtailed or diminished.  Hopefully, the revamped lineup of
services and an improved delivery system will meet your needs better both now
and into the future.  Only time will tell for sure, but initial indications
are that the CATC will be successful.
     Basic CTC services and how they are affected by CATC s evolution are
indicated below.  However, one very basic and potentially significant change
needs to be singled out. Technical assistance projects kept the CTC current
and relevant, but this type of assistance will be virtually nonexistent under
CATC.  Instead, the RBLC will become the engine for compiling and distributing
information on prevention and control technology.  As a result, substantial
improvements are planned for the RBLC (see related articles on pages 4 and 5).
In addition, CATC will focus exclusively on air pollution prevenion and
control technologies.
     Changes resulting from this evolution are being implemented gradually.
However, the CATC program will be fully implemented by October 1, 1997.

CHANGES TO CTC SERVICES

CTC HOTLINE is changing to CATC INFORMATION LINE: This change in name reflects
the less than urgent calls which dominated the old CTC HOTLINE in recent years.
The change in the level of service reflects the dramatic change from telephone
to electronic access for information services.  The CATC INFORMATION LINE will
make more (and hopefully better) use of Voice-Mail.  You will still get a real
live CATC staffer most of the time; however, if you do get Voice-Mail,
virtually all calls received during normal business hours (8:00 a.m. to 4:30
p.m. eastern time) will be answered on the same day they are received.  

ENGINEERING ASSISTANCE AND TECHNICAL GUIDANCE PRO-JECTS:  No new
major project requests are being considered.  On-going projects are being
completed (see related article on page 2).  CATC/RBLC activities will allow
for some short term, quick response assistance projects; however, major,
resource-intensive, long term projects cannot be supported by CATC with
anticipated resources.  In fact, requests for project services by state and
local agencies have diminished significantly over the past three years;
therefore, this change should not have a major impact.

HARD COPIES OF CICA REPORTS: CATC will primarily rely on electronic transfer
of CATC, RBLC and old CTC products.  With the exception of the RBLC s annual
report, hard copy reproductions of reports and products available through CATC
will be limited to supplies on hand after September 30, 1997.  Once current
supplies of hard copy products are gone, all requestors will be referred to
the CATC World Wide Web (WWW) site, EPA s Center for Environmental Research
Information (CERI), or the National Technical Information Service (NTIS), as
appropriate.  (See article on page 6 concerning disposition of excess hard
copy products.)

SMALL BUSINESS ASSISTANCE PROGRAM (SBAP): CATC will continue to provide
technical support to the SBAP as needed.  No change is anticipated for this
service.

INTERNATIONAL TECHNOLOGY TRANSFER CENTER FOR GLOBAL
GREENHOUSE GASES: CATC will continue to provide access to this center.  

CTC NEWS: This is the last formal/professionally printed edition of the CTC
NEWS.  CATC will publish a brief, photocopied newsletter focusing on
prevention and control issues periodically (about twice/year).  We suggest
that you check our WWW sites for current information on CATC and SBAP
activities, services and products.  For information on AIR TOXICS, including
schedules for MACT regulations, check out the new Unified Air Toxics WWW
site (see article on page 3)!  Other regulatory information can be found on
the Clean Air Act Amendments (CAAA) site on the OAQPS Technology Transfer
Network (TTN)2000 WWWsite (Note new TTN WWW address < http://www.epa.gov/ttn >).

CTC & RBLC BBS/WWW: The CTC and RBLC Bulletin Board Systems (BBS) and WWW
sites will be merged into one WWW site.  The TTN, which is home for the BBS,
is in the process of phasing out the BBS and converting to the WWW format.
So, the CTC and RBLC BBS are moving too, but will be united as one WWW site
under the CATC.  The RBLC data base will retain its identity and be an
important part of the CATC site.

CICA (U.S.-MEXICO BORDER INFORMATION CENTER ON AIR POLLUTION:CICA (an acronym
based on the center s Spanish name: Centro de Informacin sobre Contaminacin
de Aire) will continue and be supported by the CATC.

     If you have any comments or questions about the CATC or the changes
indicated above, please send your comments to me (E-Mail:
blaszczak.bob@epamail.epa.gov; FAX: 919/541-0242).  You can also send your
comments via the TTN BBS or through one of our WWW sites.  I and the other
CATC staffers are looking forward to hearing from you and helping you solve
your prevention and control problems.

-----------------------------------------------------------------

Control Technology Center NEWS

The CTC NEWS is a quarterly publication of the U.S. EPA s Control Technology
Center (CTC).  The CTC is an informal, easy-to-use, no cost, technical
assistance service for all State and local (S/l) air pollution control agency
and EPA Regional Office staffs.  For others, some services may be on a cost
reimbursable basis.  The CTC offers quick access to EPA experts and expertise
via the CTC HOTLINE, CTC World Wide Web Home Page and the CTC Bulletin Board,
and in-depth technical support through source specific Engineering Assistance
Projects or more generic Technical Guidance Projects.  The CTC is operated by
the Air Pollution Prevention and Control Division, National Risk Management
Research Laboratory and the Information Transfer and Program Integration
Division, Office of Air Quality Planning and Standards in Research Triangle
Park, North Carolina.

If you have any air pollution emission or control questions or would like
more information about the CTC and the types of technical assistance
available, CALL THE CTC HOTLINE!

CTC ON-GOING PROJECT COMPLETION SCHEDULES
By Bob Blaszczak, CATC/OAQPS

As indicated in the lead article on page 1, the new CATC will be dropping
major Engineering Assistance and Technical Guidance Projects from the list of
services originally provided by the CTC.  However, there are several on-going
major CTC projects that must be closed out.  The following is a list and brief
description of those projects with information on their final disposition.
Some of these projects have been around for a few years.  Most were delayed by
severe cuts in the CTC s project budget.  Some also needed to address
significant technical issues.  We apologize for any inconvenience you may have
experienced as a result of these delays and promise to do our best to finalize
them as indicated below.

Spray Gun Cleaning (CTC Project # 93-6): This project was requested by the
Sacramento Metropolitan Air Quality Management District, CA.  An emission test
protocol was developed for paint and coating spray gun cleaning equipment.
The project was delayed by concerns raised by one manufacturer of spray gun
cleaning equipment and the need to refine the testing procedure. The final
report will be available in November 1997.

Landfill Model Software Upgrade (CTC Project # 94-3): The CTC had developed a
landfill model to help affected sources determine potential emissions
consistent with the then proposed New Source Emission Standards (NSPS) for
Municipal Landfills.  More recently the CTC issued a revised Beta version of
the model consistent with the final NSPS rules.  We are in the process of
finalizing that Beta version of the model.  The final municipal landfill model
and users maual will be available in October 1997.

Emissions from Barrel Burners (CTC Project # 94-8): This project examines
emissions from open burning of household trash in barrels or drums.  The
project was requested by the New York State Department of Health which
actively participated and contributed to the project by providing analyses of
emission samples collected by the CTC in its testing laboratory.  The final
report will be available in September 1997.

Emissions from External Residential Wood Boilers (CTC Project # 94-9): The
Wisconsin Department of Natural Resources requested that the CTC investigate
these emissions units. Residential wood boilers had become somewhat popular
with some residents, but others complained about potential air pollution
problems.  To provide the state with the emission data it needed to evaluate
this potential problem, this project tested two types of boilers, single and
double pass heat exchange units, in a laboratory setting.  Emissions were
determined versus unit design, wood species, wood moisture, controls and heat
output rate.  The final report was delayed to allow for the resolution of
confidential business information (CBI) issues.  Pending successful resolution
of the CBI issues, the final report should be available in August 1997.

Soil Remediation Update (CTC Project # 95-4): This is an update to the CTC
report "Air Emissions from the Treatment of Soil Contaminated with Petroleum
Fuels" (EPA-600/R-92-124; NTIS # PB92-212976).  The new revised report will
be available in September 1997.

Vegetable Oil Manufacturing Emissions and Prevention and Control Options (CTC
Project # 95-7): This project was requested by the Maryland Air and Radiation
Management Administration to document emissions and evaluate alternative
emission prevention and control techniques for a facility that manufactures
vegetable oil and chicken meal from soybeans.  Due to technical concerns
raised by the industry, this project is on hold indefinitely.  A draft report
is available to state and local agencies from the CTC upon request.  Although
CATC is willing to pursue completion of this project and a final report,
completion is unlikely unless there is significant demand for doing so from
other state and local agencies.  If your agency is interested in seeing this
report and/or having it finalized, please contact Bob Blaszczak, CATC/OAQPS
(E-Mail:blaszczak.bob@epamail. epa.gov; FAX: 919/541-0242; telephone
919/541-5432).

CTC Products Inventory Reduction: FREE COPIES OF CTC PRODUCTS!
By Brenda Best, CATC/OAQPS

One of the changes indicated in the lead article (page 1) on the transition
from the CTC to the CATC concerns the availability of hard copies of existing
CTC and future CATC products.  For the most part, as of October 1, 1997, CATC
will be out of the hard copy product distribution business.  To reduce current
inventories of CTC products, we are offering free excess copies of products in
our inventory to you our valued customers.  Priority will be given to state
and local agencies, but otherwise these products will be available to anyone
on a first-come-first-service basis.  Check the CATC/CTC electronic bulletin
board (BBS) or World Wide Web (WWW) site for a listing of what is available
(Note: see the last page of this newsletter for BBS and WWW addresses).  If
you see something you want, just leave a message on the BBS or WWW (E-Mail)
indicating what you want (just the CTC product reference number is needed)
with your current mailing address, and we will fill your request while
supplies last.

Remember, there are no guarantees.  When the excess inventory is gone, that
will be the end.  No additional copies will be printed or distributed.  We
will update the listing of available products on the BBS and WWW sites weekly,
and we will try to let you know if we run out of copies before filling your
request.  Otherwise, allow about 3 weeks for delivery of your order.  Also
note that most newer CTC and RACT/BACT/LAER Clearinghouse (RBLC) products are
available electronically on the BBS or WWW sites.  Also, all but a few of
these documents are available for a fee through the National Technical
Information Service (NTIS), U.S. Department of Commerce by calling
(800) 553-6847.  When ordering from NTIS, use the NTIS document number (starts
with "PB") on the CTC s document listing.

RBLC:  ADAPTING TO THE NEW MILLENNIA
By Bob Blaszczak, CATC/OAQPS

The RACT/BACT/LAER Clearinghouse (RBLC), the designated engine for the new
Clean Air Technology Center or CATC (see lead article, page 1), is in the
garage for service - a long over- due tune-up and maybe a little detailing.
Several years ago the Clean Air Act Advisory Committee made a number of
recommendations for improving the Clearinghouse, but we only had enough
resources to respond to a few of these recommendations. Through some creative
thinking and moderate increases in resources, the RBLC is preparing to launch
an new era in Clearinghouse history.  As the RBLC transitions to a fully
functional World Wide Web (WWW) information source (see related article on
page 4 ), it will finally start to address a number of critical issues
including: identification and inclusion of all relevant technology
determinations; improved data quality; inclusion of estimated prevention and
control cost information; data updates to reflect as-constructed cost and
performance of technology; and information on new and emerging prevention and
control technologies.

The RBLC is working with staff in all EPA Regional Offices to establish
procedures that will identify technology applications that need to be included
in the Clearinghouse and related information and information sources.  The
RBLC is committed to using all reasonably available sources to both identify
and gather information on relevant prevention and control applications.
This includes precedent setting applications implemented to reduce emissions
below BACT and LAER applicability thresholds.  Once we identify needed
information/determinatins, we will aggressively pursue that information.

Although most state and local agencies cooperate and contribute information
to the RBLC, there are a number of agencies that don t.  We intend to remedy
this situation.  Initially we will remind agencies about their responsibilities
and the need to participate, followed by some friendly persuasion.  If
necessary, we will apply some good old fashioned arm-twisting.  We intend to
take any necessary and reasonable approach to bring a state or local agency
back into the circle.  So, if you are in one of those agencies not
participating or, worst of all, one of those agencies that use the RBLC to
gather data but never contribute, THE RBLC WANTS YOU!  RESISTANCE IS FUTILE!
WE WILL ASSIMILATE YOUR DATA!  You can come along peacefully and cooperate,
or we will be on your case relentlessly.  It s your choice.  We will prevail.

To assure that data is correct and current, the RBLC also will be developing
software features that, based on estimated construction, operation and
compliance dates, will trigger inquiries on the status of a facility.  We will
confirm that a source has been constructed, started operation, and demonstrated
compliance with permit requirements and make appropriate updates to the RBLC
data system.  In addition, we will attempt to gather as-constructed cost
information for prevention and control equipment and procedures.

The RBLC is working with the Air and Waste Management Association (AWMA) and
several trade associations to determine the feasibility of a clean air
technology WWW site to complement information in the RBLC data system.  As
currently envisioned, the clean air technology WWW site would provide access
to and querying of vendor supplied information on emerging, new and existing
prevention and control technologies.  This information would include:
description of the technology; list of industrial applications; pollutants
treated; performance/summary test data; and cost data for a typical
installation.  Links to vendor E-Mail and/or WWW sites also may be provided.
The feasibility study is underway and will be completed by September 30, 1997.
Stay tuned.  We also are exploring cooperative ventures with and links to the
New Source Review and Pollution Prevention Programs and their respective web
sites.

If you have suggestions about how we can improve the RBLC to better meet your
needs, please send your comments to me (E-Mail:
blaszczak.bob@epamail.epa.gov; FAX: 919/541-0242). You can also send your
comments via the TTN BBS or through one of our WWW sites.  I m looking forward
to hearing from you.

Simple RBLC Queries On the WWW
By Jo Ann Kerrick, INDUS Corporation

Soon, RBLC users will be able to search the RBLC database right from a web
browser.  No more complicated Telnet setup.  No more TTN user ID and password.
No more switching to our FTP site to transfer search results - if you can
remember what file name you used.  Efforts by the RBLC staff to develop
capabilities for searching the RBLC databases directly from our web page
are about to pay off. Using the "point and click" graphical environment of
the World Wide Web (WWW), users will be able to specify a simple query with
just a few mouse clicks and then view results in their web browsers. The RBLC
staff has been testing the new web database query and plans to make it
available to all users in September 1997.  We hope this enhanced capability
puts the detailed information of the RBLC within easy reach of our users.

We began our migration from the BBS to the web with the BBS Browse module
because it supports a simple query.  Users need only make two choices.  First,
they must select a date range of interest (which corresponds to the transient,
current, and historical databases from the BBS). Users must also select one
major process category or a specific process type code.  On the web, these
choices are made from drop-down lists that are displayed in the user s web
browser. This type of interface will be familiar to anyone who has used a
search engine to find information on the Web. Users are free to change their
selections if needed. Clicking a submit button on the form finds all
determinations of the specified process type in the selected RBLC database
and displays the results for viewing in the browser.

Summary results from the query are displayed in tabular format in the user s
browser. The table displays one line for each process of the specified type in
each facility added to the RBLC during the selected date range.  The display
includes the RBLC ID; facility name, city, and state; process type code; and
process description. The display should allow a user to decide whether or not a
facility is of interest.  If more detail is desired, users can drill down to
greater levels of information by clicking on hyperlinks. Users can click on
the facility name to see facility details and more process information. Then,
a pollutant list and complete pollutant information is available for every
process in the determination.  Back at the summary results table, users can
remove facilities from further output processing by clicking the check box
next to the RBLC ID.  Only designated facilities need be included in the
output report files. The familiar selection of one or more output formats will
be provided from another drop-down list on the summary table page. The user
clicks the report button to generate the report file.  Depending on how your
browser is configured, the report may appear in your browser or invoke the
file transfer dialog.  You can, of course, choose to save any report file that
appears in your browser.

The query on process type code is only the beginning of our WWW-searchable
database. As we make the transition from the text-based searching on the BBS
to the more user-friendly environment of dynamic web pages, we hope to
maintain the search and reporting functionality of the current RBLC and
possibly add features not previously possible, such as charting.  The RBLC Web
will eventually support a full set of search parameters, AND/OR connectors, and
pattern matching.  All of the web queries will allow users to choose from
drop-down lists of searchable properties and then fill in text boxes with the
value they are trying to match. Stay tuned on-line for more details as we
fully integrate the functionality of the RBLC database with the WWW.

What is the Unified Air Toxics Website?
By Dr. Nancy Pate, CATC/OAQPS

In a nutshell, it is a work-in-progress website co-sponsored by the EPA and
STAPPA/ALAPCO currently available from the Air Toxics icon on
www.epa.gov/oar/oaqps.  For several years, state and local air pollution
abatement agency staff have urged OAQPS to develop an electronic
"one-stop shopping" for air toxics information. Also, it became apparent that
many States were developing very similar communication and outreach products
independently on the same emission reduction regulations. To help stem this
duplication of effort and help foster improved communication and
information-sharing between the government co-regulators, the Unified Air
Toxics Website was born.

The Unified Air Toxics Website is managed by OAQPS s Information Transfer
Group. The full internet address is "http://www.epa.gov/oar/oaqps/airtox/". It
is hyperlinked to STAPPA/ALAPCO s website at "http://www.4cleanair@sso.org".
It includes a "State and Local Share Library" for products that state and
local agencies want to share with other agencies and EPA. In some cases, the
documents will be shared directly and in other cases, a link to information
at state and local webpages will be available.  All source categories and
emission reduction standards, knownas MACT standards, and all associated
material will be made available on the website.  For example, under a
particular source category and a particular MACT emission reduction regulation,
all internet users could find a list of work products including the rule,
guidance documents, source identification information, outreach and training
materials, permitting information and compliance and enforcement information.
Within any of these topic areas they could link to webpages of state agencies
willing to share their products.

The Unified Air Toxics Website is also available to the public. Although the
Unified Air Toxics Website is being developed with the intent of improving
communication and information-sharing between the government co-regulators,
it will serve to educate all the stakeholders, both the regulated industries
and the general public, about air pollution abatement program goals and
activities.
