Data Resources/CATC Products
The CATC WWW site provides access to CATC
products including products generated by its
predecessor, the Control Technology Center (CTC).
Products include reports, software tools, fact sheets
and brochures generated by the CATC, RBLC, CICA
and SBAP. CICA and SBAP products are accessed
through links to these specialized WWW sites.
CICA - U.S.-Mexico Border Information Center
on Air Pollution / Centra de Information
sobre Contamination de Aire
CICA provides technical support and assistance in
evaluating air pollution problems along the U.S. -
Mexico border. It provides a bilingual (Spanish/
English) information line and WWW site. The WWW
site includes air quality data for the border, information
on border air quality programs and CICA projects,
downloadable products generated by CICA and others
on border air pollution problems and solutions, and
links to other related WWW sites. Access CICA
through the CATC WWW site, or access CICA directly
at .
Small Business Assistance Program
The Clean Air Act Amendments of 1990 required that
all states develop a program to assist small
businesses in meeting the requirements of the Act.
EPA established its own Small Business Assistance
Program (SBAP), through the CATC, to provide
technical assistance to the state programs on clean air
technology and prevention issues. State small
business programs can access SBAP assistance
through CATC communication and information
services. In addition, the SBAP WWW site can be
accessed directly at
International Technology Transfer Center for
Global Greenhouse Gases
The International Technology Transfer Center for
Global Greenhouse Gases provides technology
transfer regarding greenhouse gas emissions. This
assistance includes characterizations of global
emissions from anthropogenic sources, and available
prevention, mitigation, and control technologies/
strategies for major sources of greenhouse gases.
Information is available for methane emissions from
landfills and other waste management facilities, the
natural gas industry, and coal mining. In addition,
information is available on biomass utilization for
energy generation and production of liquid fuel, and for
pollution prevention technologies.

CLEAN AIR
TECHNOLOGY CENTER
The Clean Air Technology Center (CATC) serves as a
resource on all areas of emerging and existing air
pollution prevention and control technologies, and
provides public access to data and information on their
use, effectiveness and cost. In addition, the CATC will
provide technical support, including access to EPA's
knowledge base, to government agencies and others,
as resources allow, related to the technical and
economic feasibility, operation and maintenance of
these technologies.

Communications
If you want to do things the old fashioned
way and talk to a real live person, give us
a call on the CATC Info-Line. CICA, the
CATC's technical support program for the
U.S.-Mexico border, also provides a Spanish
language Info-Line and toll-free service from
Mexico. You can call the CATC on any of these
numbers. We will be happy to answer your questions
or direct you to an EPA staff expert on the subject or
an appropriate EPA information source or service. If
you do happen to get our voice mail we will usually get
back to you the same day. Our normal business hours
are 8:00 a.m. to 4:30 p.m. eastern time Monday
through Friday. Voice-mail is available during non-
business hours and we will return your call the next
business day.
Data Resources/RBLC
CATC maintains a technology data base called the
RACT/BACT/LAER Clearinghouse' or RBLC. The
RBLC provides data on prevention and control
technology determinations made primarily by state
and local permitting agencies. The Clearinghouse
contains over 3,500 determinations that can help you
identify appropriate technologies to mitigate or treat
most air pollutant emission streams. The RBLC was
designed to help permit applicants
and reviewers make pollution
prevention and control
technology decisions for
stationary air pollution sources
and includes data submitted
by 50 states and territories in
the U.S. on over 200 different air
pollutants and 1,000 industrial
processes.
The Clearinghouse also has a rule data base that
summarizes all emission standards issued by EPA's
Office of Air Quality Planning and Standards
(OAQPS). This includes new source performance
standards (NSPS), national emission standards for
hazardous air pollutants (NESHAP), and maximum
achievable control technology (MACT) standards.
The rule data base also includes prevention and
control technology cost information related to each
rule and references to supporting documentation.
You can query the RBLC data on-line or download a
stand-alone desktop version to run on your own
personal computer (PC). You choose what you want
to see by making selections in a user-friendly query
" NOTE: Are you wondering what "RACT. BACT and LAER" stand
for and why these acronyms are part of the Clearinghouse name?
Well, they are acronyms for different program requirements required
under the Clean Air Act which also gave us the name "RACT/BACT/
LAER Clearinghouse." RACT, or Reasonably Available Control
Technology, is required on existing sources in areas that are not
meeting national ambient air quality standards (i.e.,non-attainment
areas). BACT, or Best Available Control Technology is required on
major new or modified sources in clean areas (i.e., attainment
areas). LAER, or Lowest Achievable Emission Rate, is required on
major new or modified sources in nonattainment areas. However,
data in the Clearinghouse is not limited just to sources subject to
these requirements. Noteworthy prevention and control technology
decisions are included in the RBLC even if they are not related to
RACT. BACT, or LAER decisions.
