                                        Out with the old!
           By Bob Blaszczak
      It's time to make a change. It's time
   to say goodbye to the CTC and wel-
   come the CATC.  It may not be revolu-
   tionary but most definitely it is evolution-
   ary.  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
      As the offspring of the CTC and
   RBLC, CATC retains  the  same basic
   characteristics of both of these  pro-
   grams but has adapted to the new reali-
   ties of cyberspace information transfer
   and fiscal restraint.  The good news is
                        In with the new!
    that we will still be here to provide tech-
    nical assistance to you, our valued cus-
    tomer. The bad news is that some of the
    services that the departing CTC offered
    will be curtailed or diminished.  Hope-
    fully, 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. Techni-
      cal 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 compil-
      ing and distributing information
      on prevention and control tech-
      nology. 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 prevention
and control technologies.
   Changes resulting from this evolu-
tion are being implemented  gradually.
However, the CATC program will be
fully implemented by October 1, 1997.

      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 Technol-
   ogy 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 custom-
                      ers,  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 Clearing-
                      house (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 Divi-
                      sion (APPCD), National Risk Management Research Labo-
                      ratory, Office of Research and Development (ORD), will not
                                                    (continued page 6)

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

JECTS: No new major project requests
are  being  considered.  On-going
projects are being completed  (see re-
lated 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 dimin-
ished significantly over the past three
years; therefore, this change should not
have a major impact.

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 repro-
ductions of reports and products avail-
able 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 Infor-
mation Service (NTIS), as appropriate.
(See article on page 6 concerning dis-
position of excess hard copy products.)

PROGRAM  (SBAP): CATC will con-
tinue to provide technical support to the
SBAP as needed. No change is antici-
pated for this service.

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.

LUTION: CICA (an acronym based on
the center's Spanish name: Centro de
Information sobre  Contamination de
Aire) will continue and be supported by
the CATC.

tions about the  CATC  or the changes
indicated above, please send your com-

CATC  staffers are looking forward  to
hearing from you and helping you solve
your prevention and control problems.

         By Dr. Nancy Pate

    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 ap-
parent that many States were develop-
ing very similar communication and out-
reach 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 gov-
ernment 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, known as
MACT standards, and
all associated material
will be made available
on the website.  For
example, under a par-
ticular source category
and a particular MACT
emission  reduction
regulation, all internet
users could find a list of work products
including the rule, guidance  docu-
ments, source  identification informa-
tion, 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
                 between the gov-
                 ernment co-regula-
                 tors, it will serve to
                 educate  all  the
                 stakeholders, both
                 the regulated indus-
                 tries and the gen-
                 eral public, about air

        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 TIN user ID
and password. No more switching
to our FTP site to transfer search
results -  if you  can remember
what file  name you used.  Ef-
forts by the RBLC staff to de-
velop 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 re-
sults 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
    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  corre-
sponds to the transient, current, and
historical  databases from the  BBS).
Users must also select one major pro-
cess category or a specific process type
code. On the web, these choices  are
made from drop-down lists that are dis-
played in the user's web browser. This
type of interface will be familiar to any-
one 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 re-
sults 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 dis-
play 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 in-
formation is available for every process
in the determination. Back at the sum-
mary 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 gen-
        erate the report file. Depend-
        ing  on how your browser is
        configured, the report may ap-
        pear 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 da-
        tabase. As we make the tran-
        sition from  the text-based
        searching  on the BBS to the
        more user-friendly environ-
        ment of dynamic web pages,
        we  hope  to  maintain the
        search and reporting function-
        ality  of the current RBLC and
        possibly add features not pre-
        viously  possible,  such  as
      charting.  The RBLC Web will
     eventually support a full set of
   search  parameters, AND/OR con-
 nectors, and  pattern matching.  All of
the web  queries will allow users  to
choose from drop-down lists of search-
able properties and then fill  in text
boxes with the value they are trying to
match. Stay tuned on-line for more de-
tails as we fully integrate the functional-
ity  of the RBLC database with the

         By Bob Blaszczak

    The RACT/BACT/LAER Clearing-
house (RBLC), the designated engine
for the new Clean Air Technology Cen-
ter 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 re-
spond to a few  of
these recommen-
dations. Through
some     creative
thinking  and moder-
ate increases in re-
sources, the RBLC
is   preparing   to
launch an new era in
Clearinghouse his-
tory. 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 rel-
evant technology determinations; im-
proved  data quality; inclusion  of esti-
mated prevention and  control cost in-
formation; data updates to reflect as-
constructed cost and performance of
technology; and  information on new
and  emerging prevention and control
    The RBLC is working with staff in all
EPA Regional Offices to establish pro-
cedures that  will identify technology
applications that need to be included in
the Clearinghouse and related informa-
tion  and information sources.  The
RBLC is committed to using all reason-
ably available sources to both identify
and gather information on relevant pre-
vention and  control applications. This
includes precedent setting applications
implemented to reduce emissions be-
low  BACT and LAER  applicability
thresholds.  Once we identify needed
information/determinations, we will ag-
gressively pursue that information.
    Although  most state and  local
agencies cooperate and  contribute in-
formation  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 partici-
pate, followed by some friendly persua-
sion. If necessary, we will apply some
good old fashioned arm-twisting.  We
intend to take any necessary and rea-
sonable 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
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 develop-
ing 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 con-
structed, started operation, and demon-
strated compliance with permit require-
ments and make appropriate updates to
the RBLC data system. In addition, we
will attempt to gather as-constructed
cost information for prevention and con-
trol equipment and procedures.
   The RBLC is working with the  Air
and Waste Management Association
(AWMA) and  several trade associa-
tions 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 emerg-
ing, new and  existing prevention and
control technologies.  This information
                   would  include:
                   description of the
                   technology; list of
                   industrial  appli-
                   cations;  pollut-
                   ants treated; per-
                   mary  test data;
                   and cost data for
                   a typical installa-
                   tion.   Links to
                   vendor  E-Mail
                   and/or   WWW
sites also may be provided. The feasi-
bility 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 respec-
tive web sites.

we can improve the RBLC to better
meet your  needs, please  send your
comments to  me (E-Mail:   blaszczak

be a CATC sponsor.   Although the
APPCD has graciously indicated its will-
ingness  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 coopera-
tive 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 posi-
tive experience that exceeded every
expectation.  We will  sincerely miss
Charlotte Bercegeay, APPCD CTC Co-
Chair, Lyn Cox,  the CTC HOTLINE'S
premier  senior engineer, and all the
APPCD  staff who have supported the
CTC and its work through  the years.
Thanks for 10 productive years of coop-
eration 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 bud-
gets, I guess that was not totally unex-
pected.  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 grow-
ing! In fact, the CTC will close out with
an all time record high in the number of
accesses to its services. What an awe-
some 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 actu-
ally  downloaded (i.e.,  we only count
downloads and multiply that by the his-
toric 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!

    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 prod-
 uct distribution business.  To reduce
 current inventories of CTC products, we
 are offering free excess copies of prod-
 ucts in our inventory to you our valued
 customers. Priority will be given to state

    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 signifi-
cant technical issues.  We
apologize for any inconve-
nience you may have expe-
rienced 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 Metropoli-
tan Air Quality Manage-
ment District, CA.  An emis-
sion test protocol was  de-
veloped for paint and coat-
ing 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
Landfill Model Software Upgrade
(CTC  Project # 94-3): The CTC had
developed a landfill model to  help af-
fected  sources determine  potential
emissions consistent with the then pro-
posed  New Source Emission  Stan-
dards (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 manual will be avail-
able in October 1997.
Emissions from Barrel Burners (CTC
Project # 94-8): This project examines
emissions from open burning of house-
hold  trash in barrels or  drums.  The
project was requested by the New York
State Department of Health which ac-
tively participated and contributed to the
project by providing analyses of emis-
      sion  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 Wis-
      consin Department of Natural
      Resources  requested that the
CTC investigate these emissions units.
Residential wood boilers had become
somewhat popular with  some  resi-
dents, but others complained about po-
tential air  pollution problems. To pro-
vide 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 infor-
mation (CBI) issues. Pending success-
ful resolution of the CBI issues, the final
report should be available  in August
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 re-
vised report will be available in Septem-
ber 1997.
Vegetable Oil Manufacturing Emis-
sions and  Prevention  and Control
Options  (CTC Project # 95-7):  This
project was requested by  the Maryland
Air and Radiation Management Admin-
istration to  document emissions  and
evaluate  alternative emission preven-
tion and control techniques for a facility
that manufactures vegetable oil  and
chicken meal from soybeans. Due to
technical concerns raised by the indus-
try, 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 agen-
    cies. If your agency is interested in
    seeing this report and/or having it
    finalized, please  contact  Bob
    Blaszczak,  CATC/OAQPS(E-
epa.gov;  FAX:  919/541-0242;  tele-
phone 919/541-5432).
