PREFACE,
The Control Technology Center (CI'C) is a cooperative effort between the U.S. Environmental
Protection Agency's (EPA's) Office of Air Quality Planning and Standards (OAQPS), Emission
Standards Division (ESD), and the Office of Research and Development (ORD), Air and Energy
Engineering Research Laboratory (AEERL). The erc provides technical assistance and technology
transfer to state and local air pollution control agencies and to EPA's regional offices on air pollution
contr~l technology and pollution prevention applications. It also provides technical information to
other governmental agencies, both foreign and domestic, and to private entities on a limited basis.
erc activities include the Federal Small Business Assistance Program (SBAP) and the
RACI'IBACI'ILAER Clearinghouse (RBLC). '
The ere produced this report to inform EP A management, staff and other interested
individuals of the status and activities of the erc in supporting the nation's air quality program. This
, report summarizes CI'C projects and other program activities conducted between October 1, 1992, and
September 30, 1993. Also, program statistics are presented and analyzed to allow management staff to
evaluate the erc's progress and effectiveness. Finally, the report documents the demand for CTC
support activities from businesses and governmental agencies.

EXECUTIVE SUMMARY
INTRODUCTION
The Control Technology Center (erC) services were accessed more than 30,000 times in
FY93, which is double the amount of activity experienced in FY92. This includes HOTI-INE calls,
access to computer bulletin board systems (BBSs) and databases, and requests for CTC products. This
report summarizes the erc's activities and accomplishments during FY93 and examines strategies to
sustain this dynamic program.

CTC PROGRAM SERVICES
A brief summary of ere services and activities follows. The flow chart on the following
page illustrates the operation of the ere Program. More detailed infonnation on each activity is
provided in Section 2 of this report.
ere HOTI.INE
Ala The ere's telephooe H01LJNE provides quick access 10 EPA informatioo and
- expertise. In FY93, HOTI.INE activity increased by 22 percent, about half the
increase experienced in FY92. State, local, and federal government agency calls decreased slightly,
but non-government HOTI.INE calls continued to rise to represent 62 percent of all HOTLINE calls.
This leveling off of HOTI.INE activity may be attributable to the growing popularity of the CTC
BBSs.
CTC Bulletin Board System
The CTe BBS completed its second full year of service with a 91 percent increase in
activity. The BBS is part of the OAQPS Technology Transfer Network (TTN). It
provides around-the-clock access to CTC services to anyone with a personal computer,
a modem, and appropriate software.
RACTIBACTILAER Clearinghouse
The RACI'IBACI'ILAER Clearinghouse (RBLC), a repository for state and local
agency control technology determinations, can be easily accessed with a personal
computer equipped with a modem and communications software for the price of a
telephone call. FY93 was the RBLC's fIrst full year of operation as a BBS. Use of
the system increased more than 500 percent above its mainframe-based predecessor.

Federal Small Business Assistance Pro21'3l11
The CTC is the focal point of coordination for the existing EP A technical
assistance centers participating in the Federal Small Business Assistance
Program (SBAP). The other centers include the Emission Measurement Technical Infonnation Center
(EMTIC), the Chemical Emergency Preparedness and Prevention Office (CEPPO), the Pollution
Prevention Information Center (PPIC), and the EP~ Small Business Ombudsman's Office. In FY93.
the Federal SBAP coordinator participated in several regional meetings, initiated development of an
SBAP BBS, and began work on the first annual SBAP Technical Assistance Program Conference.
SBAP news also became a standard feature of the CTC's quarterly bulletin, "CTC News," in FY93.
Enlrineerin~ Assistance and Technical Guidance Proiects
~
The CTC funded 13 new technical guidance or engineering assistance projects during
FY93. Many of these 'projects resulted from HOTLINE and written requests for
technical assistance. In addition, the CTC completed 14 projects, three of which were initiated in
FY93.
CTC Products
~
As part of its technology transfer effort, the CTC distributed 7,371 reports and
software tools that resulted from CTC projects. These products were requested by
and provided to government agencies free of charge. Other requestors were directed to the National
Technical Infonnation Service (NTIS) or the CTC BBS. Products acquired through NTIS or
downloaded from the CTC BBS are not included in this total.
Outreach Activities
The CTC conducted several outreach activities during FY93. More than 5,000 copies of
CTC's quarterly bulletin, "CTC News," were mailed to CTC clients each quarter in FY93.
In addition, the erc participated in the Air and Waste Management Association's national
conference and several EP A workshops.
xii
-------
International Technolol!'V'Transfer Center for Global Greenhouse Gases
~
To date, modest funding has been provided to develop technology transfer tools for
waste methane sources. The initial emphasis was on landfill methane because of
soon-to-be final air rates rules for municipal solid waste landf1lls. Further highlights in the area
include plans for a research symposium on greenhouse gas emissions, planned for spring 1995.
Technical assistance and information are available on landfills and other waste management
sources, coal mines, natural gas industry; small-scale combustion services (including coal stoves), and
biomass utilization.
RESOURCES
The erc expended $475,000 in contract funds on engineering assistance and technical
guidance projects during FY93., This amount is a 20 percent decrease from the $592,000 the CTC
expended on projects in FY92. This does not include funding for the Federal SBAP and the RBLC
programs. These programs are funded under separate allotments not directly associated with CTC
funding. RBLC expended $100,000 for maintenance and improvements in FY93. The Federal SBAP
.'
is using its $100,000 FY93 budget to develop a small business bulletin board and to hold a national
SBAP conference. In addition to contract funds, the CTC expended 6.6 person years of EP A staff
time implementing its programs.
PROGRAM DEVELOPMENT
erc is planning a number of initiatives including the following:
. Building pollution prevention capacity
. Developing an innovative technologies electronic bulletin board
. Expanding cooperative projects with industry
. Developing cost recovery procedures under Section 112(1)(3), of the Clean Air Act (CAA)
. Developing the capacity to evaluate cross-media impacts of air pollution control
technology applications
xiii
-------
The Federal SBAP will also establish an SBAP BBS to promote timely coordination and sharing of
infonnatioo, and initiate the Leadership Grants Program to promote innovative approaches to small
business assistance.
SUMMARY
The erc continues to experience significant growth and program expansion. Most of these
challenges have been met through the use of electronic BBSs. As a result, the CTC effectively
doubled its capacity and increased user access with no change in staff resources and a decrease in
project funding compared to FY92.
The best indicator of CTC program success is client access and use of CTC services. Access
to CTC services doubled again in FY93 and now exceeds 30,000 accesses per year. Although access
to existing CTC services is expected to moderate, new activity generated by the Federal SBAP and the
Innovative Technology/Pollution Prevention BBS is expected to result in significant growth in the
. .
future.

SECTION 1.0
INTRODUCTION
The Control Technology Center (CTC) has completed its seventh year of successful operation
and expansion'in providing technical assistance. In addition to basic program activities, CTC activities
include the RACTIBACTILAER Clearinghouse (RBLC) and the Federal Small Business Assistance
Program (SBAP). The CTC also acts as a. contact point for and distribution center of products
prepared by the International Technical Infonnation Center for Global Greenhouse Gases (GGG). This
report summarizes the operation and accomplishments of the CTC during FY93. It documents the
program's efforts during this period to respond to increased demands for technical assistance and
infonnation from the air pollution control community. It also discusses the growth and evolution of
the erc since its conception in 1987, as well as its efforts and plans to meet client needs in the
future.
The erc was originally established to support the U.S. Environmental Protection Agency's
(EPA's) Air Toxics Strategy. The strategy called for state and local agencies to assume regulatory
responsibilities for toxic air pollutants with EPA providing technical assistance to support their efforts.
In response, EPA's Air and Energy Engineering Research Laboratory (AEERL) and the Office of Air
Quality Planning and Standards (OAQPS) developed and implemented an innovative technology
assistance and transfer program-the CTC. In addition to supporting state and local agency air toxics
programs, the CTC was also charged with providing technical assistance to these agencies on volatile
1
-------
organic compound (VOC) control issues to support their efforts to attain the national ambient air
quality standard (NAAQS) for ozone.
The erc's mission has expanded significantly over time. RBLC responsibilities had been
.
assumed by erc staff as an independent program since the erc's inception; however, the relationship
proved to be extremely beneficial to both activities. The RBLC became an important tool in
responding to client requests for technical assistance about control technology applicability and
performance. At the same time, the erc technical assistance role proved to be a logical response to
. .
RBLC clients in need of more in-depth technical assistance. The expansion of the RBLC to include
~easonable Available Control Technology (RACT), as required by the 1990 Clean Air Act
Amendments (CAAA), also resulted in a more interconnected relationship between these two activities,
RACT supports efforts to attain the ozone NAAQS, a basic CTC function. As a result, the CTC and
RBLC now function as one 'integrated program.
The CAAA also effected other significant changes. The most critical change was the
extension of erc services to non-governmental clients. The private sector now accounts for more
than 60 percent of the erc's activities. In addition, because of its well-established role in assisting
state and local agencies, EP A also decided to make the CTC the focal point for the Federal SBAP
required in Section 507 of the CAA. The role of the Federal SBAP is to provide technical support
and coordination to state SBAPs.
EP A policy and the needs of erc clients require that the CTC continue to adapt and change.
The erc will build pollution prevention capacity into its program. As part of this effort, the Center
plans to establish an innovative technology/pollution prevention information transfer system to provide
quick and timely information exchange among developers, vendors, industry, and regulatory agencies.
The erc will also need to develop capacity to consider cross-media implications of air pollution
control technology applications, and the ability to work with industry in assessing new and emerging
technologies.

2.1 THE ere HO'IUNE
The ere operates a telephone H01UNE service staffed
by technical experts from the sponsoring organizations. The
H011.INE provides callers with quick access to EP A air pollution
control infonnation and expertise during regular business hours
(7:30 a.m. to 5:00 p.m. Eastern time). Most simple teChnical
assistance requests can be addressed immediately by ere staff. When a more detailed analysis or
evaluation of a request is required, it is referred to an expert in the particular field.
The ere initiated its computer tracking system for H011.INE calls in FY87. Computer data
and other early ere records show a continued growth over the program's seven-year history. The
HOTLINE Fceived 3,353 calls for assistance in FY93 (this figure does not include requests for CTC
products). 'Ibis represents an overall increase in HOTLINE activity of 22 percent, about half the rate
of increase experienced in FY92. This leveling off of H011.INE activity may be attributable in part
to the growing popularity of ere electronic BBSs which experienced a tremendous increase in activity
in FY93,
For the first time since the ere began its HOTLINE. calls from state. local, and federal
governmental agencies decreased slightly. H011.INE calls from governmental agencies totaled 1,258
in FY93 compared to 1,309 in FY92 (a decrease of 4 percent). This appears to be the culmination of
a gradual leveling off in government calls that has been experienced in recent years.
Non-governmental callers now represent 62 percent of all HOTLINE calls. Non-governmental
HOTLINE calls increased from 1,441 in FY92 to 2,095 in FY93, a 45 percent increase over FY92
activity. About 700 additional calls have been received from non-governmental callers each year since
.the 1990 eAAA required that the erc make its services available to others (i.e., other than
governmental agencies). Although the actual increase in the number of non-governmental calls has
4
-------
been constant, the r8te of increase in non-governmental calls in FY93 was about half that experienced
in FY92.
Figure 2 shows the increase in HOTI..INE calls over the last three fiscal years and the impact
of private sector calls on the totals.
An analysis of HOTI.INE calls reveals that major topics for technology assistance by both the
governmental and privat~ sectors fall into similar poUutant and subject/process areas.
As indicated in
Table 1, the top four HOTI.INE pollutant topics accounted for 77 percent of all calls where a pollutant

of Air Quality Planning and Standards (OAQPS) Technology Transfer
Network (TI'N) BBS and can be accessed via a personal computer (PC)
equipped with communication software and a modem. The BBS operates
around-the-clock except for routine maintenance on Mondays between 8:00
a.m. and noon Eastern time. The BBS allows the user to access CTC-generated technical reports and
software, which may be downloaded to the user's PC. The user may also leave requests for assistance
or solicit input from other users by posting questions and'requests on the BBS.

The CTC BBS has become an important and popular part of the CTC. It has allowed the CTC
to expand its services and technology transfer capability with only a minimum impact on resources.
New CTC products will be available as downloadable files from the BBS. This will increase user
access to this information and potentially reduce printing and document handling costs. The erc
BBS is also being considered as the location for an innovative technologies database that will allow
users to identify and access information on new and emerging pollution control and prevention
methods.

2.3 RACfIBACf/LAER CLEARINGHOUSE
The RBLC is a repository for state and local agency control
technology detenninations. It includes control technology
detenninations for the following:
.
Major new or modified sources located in non-
attaiDlDent areas and subject to Lowest
Achievable Emission Rate (LAER) control
requirements
iill
I~&\
0-
Major new or modified sources located in

Control Technology (BACT) requirements under
the. Prevention of Significant Air Quality Deterioration.Program
.
,
.
Existing. sources located in non-attainment areas and subject to Reasonably
Available Control Technology (RACT) requirements
The RBLC allows anyone with a PC, modem, and communications software to review, browse, and
print examples of the types of controls required or used on similar sources. In addition, RBLC also
contains the name, agency, and telephone number of a contact to obtain additional in-depth
information on those sources.
During FY93, the RBLC was accessed 11,561 times, representing a 503 percent increase over
FY92. This tremendous increase in use probably resulted from moving the RBLC to the OAQPS TIN
in late FY92. Before that time, the RBLC had been on EPA's mM mainframe computer. Security
and administrative procedures significantly inhibited direct user access to Clearinghouse data. Even
after installing more user-friendly programming, the old mainframe system averaged only about 120
accesses per month. The BBS version in FY93, its first full year of operation, averaged almost 1,000
accesses per month. More than half of those accesses resulted m a download of substantive
information from the RBLC database. In addition to being moved, the RBLC was revamped to
include many new data elements. This provides the user greater freedom in searching, retrieving,
formatting, and downloading data. The new system also allows direct updating by authorized state
10

The RBLC is in the process of implementing a number of improvements including the
following:
.
Full utilization of statistical ranking capabilities based on standardized
emission units
.
A rule database which includes a summary of requirements of all federal air
emission standafds and provides for direct entry of similar infonnation by state
and local agencies
.
Direct computer-based data transfer between the California Air Resources
Board Clearinghouse and the RBLC
.
A standardized floppy disk data transfer program to facilitate data submission
by state and local agencies
.
An interactive PC program to familiarize new users with RBLC capabilities
and procedures
The RBLC has also taken part in discussions concerning additional improvements and
expansion of Clearinghouse capabilities that are being evaluated by the ongoing New Source Review
Refonn Workgroup. Many of the actions being discussed by the Workgroup are dependent on making
the RBLC more comprehensive and complete with regard to new source pennitting and emerging
emission control technologies. Improvements to the RBLC that would enhance its ability to present
pollution prevention information are also being considered as part of the Environmental Technology
Initiative.

2.4 FEDeRAL SMALL BUSINESS ASSISTANCE PROGRAM
Under Title V, Section 507, of the 1990
. CAAA, EP A is required to provide assistance to
.
the State Small Business Stationary Source
Assistance Programs. The Federal SBAP is a
Technical and Environmental Compliance
coordinated effort among several existing EP A
technical service centers. The CTC serves as the
focal point for coordination of efforts among the participating groups, as well as the contact point for
,
general Office of Air and Radiation (OAR) small business assistance activities. EPA's assistance
centers associated with this program include: the CTC, the Emission Measurement Technical
Information Center (EMTIC), the Chemical Emergency Preparedness and Prevention Office
(Emergency Planning and Community Right-to-Know Information Hotline), the Pollution Prevention
Information Center (PPIC), and the EP A Small Business Ombudsman's Hotline. These centers are
expanding their services to provide support to state and local agencies as they develop SBAPs, and on
a continuing basis as these programs become operational (no later than November, 1994). They will
also be able to assist small businesses in understanding and complying with CAAA requirements in
their respective program areas.
Several briefings were held this year to introduce the Federal SBAP to the ESD regulatory
development staff and discuss the need for development of materials to explain new emission
standards to small businesses. Beginning in FY94, the Federal SBAP will coordinate the development
of information for use by the State SBAPs in educating small businesses. These materials will include
simplified fact sheets prior to proposal of a rule, and documents written in layman's terms to explain
. .
the requirements of final rules. These materials may also contain compliance options, including
13
-------
pollution prevention alternatives. where appropriate. To assist in the development of information for
small businesses, the erCIFederal SBAP has issued" A Guidebook for Explaining Environmental
Regulations to Small Businesses" (See Appendix C). This Guidebook addresses this issue in general
terms, in order to be useful not only to EP A staff, but also to state and local agencies as well as the
public at large.
During FY93, the erc Federal SBAP Coordinator presented discussions on services available
through the Federal SBAP and Section 507 implementation issues, at regional meetings of the State
. SBAPs in New Orleans, LA; Raleigh, NC; and Portland, OR. A similar discussion was presented at
the annual EPA Regional Small Business Liaison's meeting, and another will be given at the First
,
Annual National Small Business Ombudsman's CQnference in Washington, DC, in early FY94. The
CTC Federal SBAP Coordinator also participated in the development of testimony concerning the
implementation of Section 507 of the CAAA. This testimony was given by the Director of OAQPS
before the U.S. Senate Subcommittee on Clean Air and Nuclear Regulation of the Committee on
Environment and Public Works.
The "SmaIl Business Update" is now included in each edition of the "CTC News" to discuss
Federal SBAP activities. Developmental work has begun on the Small Business BBS, to be included
on the OAQPS TTN by mid-FY94. The Small Business BBS will provide an avenue for state and
local SBAPs and EPA to share materials for use in assisting small businesses. Planning activities are
under way for the First Annual National Small Business Technical Assistance Conference. to be hosted
by the CTClFederal SBAP in January. 1994. Also planned for FY94 is the establishment of the
Leadership Grants Program to benefit innovative approaches to small business assistance by the state
Section 507 programs.

impacting the development of regulatory programs' do not
research projects for its clients. Many technical issues
fall within EP A's traditional research and development
activities. The CTC is designed to conduct non-
traditional technical and research studies that support state and local agencies and businesses in
developing regulatory and compliance agendas and pollution control strategies. Most of these studies
are requested and defined by state and local governmental agencies. Others are identified by CTC
management and are based on the volume of technical assistance requests on specific topics presented
during HOTLllffl calls and/or other technical assistance communications. Since its inception, the CTC
has completed more than 100 studies to fulfill its technical assistance mandate. Many of these
products have been recognized as authoritative resources on these subjects.
The erc initiated 13 projects in FY93. A brief description of these projects is found in
Appendix A. They include the following:
.
Two program administration/quality control projects designed to monitor,
track, support, and improve the operation of the CTC and its projects
.
Seven engineering assistance projects in response to requests received from
various state and local governmental agencies
.
Four technical guidance projects in response to HOTLINE requests and the
need to upgrade existing CTC products
Direct engineering assistance projects are initiated when a state or local agency requests
technical assistance in spedfic areas (either through the HOTLINE or by written request). These
projects are usually short-teno, take about three to six months to complete, and involve the evaluation
of emissions, emission control technologies, or pollution prevention methods for certain operations.
15
-------
Technical guidance projects result from multiple HOTLINE requests for technical assistance in a
particular topical area. The projects are usually long-tenn, take about one year to complete, and are
applicable to a broad client base. Both types of projects are generally conducted for governmental
clients free of charge dependmg on the availability of funds. However, the ere has on occasion
entered into joint ventures with other agencies in order to conserve and leverage limited resources. If
the current trend of decreasing funding continues, the ere will increasingly seek out these joint
ventures.
The ere completed 14 technical projects in FY93. They include three projects initiated in
FY93 and six projects initiated in FY92. The five remaining projects completed were initiated prior to
FY92. These CTC products address a wide range of issues, including controlling particulate .emissions
from grain handling, mercury emissions from fluorescent lamp crushing, styrene emissions from
fiberglass products manufacture, and HAPs from leather tanning and coating. Other projects addressed
potential HAPs emitted when burning fiberglass, fluff (the non-metallic residue of scrapped
automobiles), and scrap from wood cabinet manufacturing. The CTC also completed the first step in
upgrading its popular software tool called HAP-PRO~ HAP-PRO is a PC-based program that helps
evaluate control options for HAPs. A complete list of projects completed in FY93 is provided in
. Appendix B.
Currently, the CTC only accepts projects requested by governmental agencies (primarily state
and local air pollution control agencies). Projects requested by non-governmental clients are not
accepted because, to date, neither cost recovery procedures required under Section 112(1)(3) of the
CAAA nor federal funding to conduct such projects have been provided for this client group.
However, the ere has entered into several joint agreements with non-governmental clients. Among
. .'
these agreements are the following:
1.
An agreement with the Electric Power Research Institute (EPRI) to jointly
develop PC-based software to evaluate and design electrostatic precipitators
(ESPs). The CTC provided an existing internal EPA ESP evaluation program
16
-------
and technical expertise. EPRI provided programming expertise and resources.
A comprehensive ESP design model has been developed and is available
through the CTC BBS, free of charge, to anyone wishing to download it. This
comprehensive model is the property of EP A. EPRI is still refining a less
sophisticated, user-friendly version. The EPRI version is the property of EPRI;
however, a licensing agreement between EP A and EPRI will allow the CTC to
distribute this version to state and local agencies free of charge.
2.
An agreement with Weatherly, Inc., the distributor of The Polyad@ FB
Process, aild Eljer Plumbingware, Inc., to test and evaiuate the effectiveness of
Weatherly's styrene emission control system. Weatherly provided a Polyad@
FB control system and transportation, installation, operation, and removal of
the system from the site of the Eljer Plant in Wilson, NC. Eljer provided an
emission source from its manufacturing process and on-site utilities needed to
operate the control system. EP A provided for stack testing and generated an
independent report evaluating the performance of this control system in
tteating styrene emissions.
,
3.
An agreement with QUAD Environmental Technologies, manufacturer of the
QUAD ChemtactTM System, and Eljer Plumbingware, Inc., to test and evaluate
the effectiveness of QUAD's styrene emission control system. The
arrangement was very similar to that described in 2 above.
, These projects, especially 2 and 3 above, were very significant. They demonstrated the CTC's
. '
'ability to work with the private sector and produce an inde~ndent evaluation of emerging control
technology. Control of styrene, a HAP, has been troublesome for more conventional control systems
because of cost or technical feasibility issues. The erc hopes to continue this type of project because
it puts the erc on the cutting edge of technology and provides valuable information to industry and
regulatory agencies wrestling with air pollution control questions. The CTC would also like to pursue
the establishment of cost-reimbursable procedures that may' facilitate future evaluation of emerging
technologies and eliminate or minimize CTC costs.

recent resource materials in the "CTC News." Governmental clients receive the available reports and
software systems at no charge. Non-governmental clients receive information about ordering these
items from NTIS. In addition, many of these items can be downloaded by anyone through the CTC
BBS at the cost of a telephone call. The erc mailed 7 ,371 tec~ical assistance reports and computer
disks to clients in FY93. The increasing number of publications and software distributed by the CTC
each fiscal year is evidence that CTC products have gained in popularity. Titles of CTC reports and
software available through the end of FY93 are listed in AppendiX C.
The CTC is also using its bulletin board to distribute the PC program "Solvent Alternative
GuidE" (SAGE). This software tool was developed by staff at AEERL, one of the CTC's sponsoring
organizations. SAGE helps users identify more environmentally friendly solvents by answering basic
questions about the product they are manufacturing, the material with which they are dealing, and
processes involved. As seen in Table 4, SAGE is a very popular downloadable item. About 400
copies were downloaded from the BBS in FY93.
2.7 OUTREACH ACTIVITIES
The CTC publishes the "CTC News" quarterly to inform its
audience of available services, the status of CTC projects, and other
activities related to air emissions and control technology. It identifies new
projects and those nearing completion. The "CTC News" also highlights
EPA staff members who respond to assistance requests. The quarterly
publication often solicits from its readers information related to ongoing
projects or requests for erc assistance and suggestions for ways in which
the program may better serve their needs~ In FY93. the "CTC News" reached a mailing list of more
than 5,000 clients per quarter, a 32 percent increase over the FY92 mailing rate.
18
-------
In addition to the "CfC News." the ere updates clients and infonns potential users of its
services by conducting briefings at EP A regional offices and other locations. In FY93, the erc staff
attended workshops and conferences such as the Office of Air Quality Planning and Standards Air
Quality Management Workshop, CAA Title ill Implementation Workshop, and the Air and Waste
Management Association Conference; As appropriate, program briefings, seminars, and conference
presentations or interactive displays were used to promote erc program objectives and services.
2.8 INTERNATIONAL TECHNOLOGY TRANSFER CENTER FOR GLOBAL
GREENHOUSE GASES
The United Nations Conference on Environment and
. .
Development (UNCED), held in Rio de Janeiro in June 1992,
created an unprecedented need for rapid and effective transfer
of technology and information regarding emissions
measurements methodology and inventory development, and
technology development, demonstration, and deployment.
. .
The EPA and the U.S. technical community have extensive expertise on greenhouse gas (GHG)
emissions and controls. This will continue to grow as the global change research program progresses.
The goal of the International Technology Transfer Center for Global Greenhouse Gases (ITrCGGG) is
to provide access to this expertise and to respond'to incoming requests both domestically and
internationally for information on greenhouse gas emissions.
A modest program within AEERL has already begun to provide information on emissions and
strategies to a variety of information users. In 1992, ITrCGGG, a part of EPA's erc was
established. Since its inception in May 1992, mCGGG has received hundreds of calls and requests
for information. FY91 and FY92 funding was applied to developing an EPA report on the
technological options and case studies on landfIll gas utilization. To date. more than 1,100 copies of
this report have been distributed. A follow-up report is being developed that contains information on
19
-------
landfill gas-to-energy projects in North America, Europe, and Australia. This report will provide an
overview of the different philosophies about gas cleanup and energy equipment modifications for
landfill gas utilization. Information in this report is being provided through the International Energy
- Agency Expert Working Group on landfIll Gas, in which AEERL participates. Another
accomplishment isAEERL's first symposium on GHG emissions and mitigation research which was
held in Washington, DC, in August 1992 and was attended by more than 300 participants.
A second
research symposium is planned for the spring of 1995.
Information on the following subjects is available through mCGGG:
.
Landfills and other waste management facilities, the natural gas industry, and
coal mining ,
.
Biomass utilization for energy generation and production of liquid fuel and for
pollution prevention technologies .
.
Energy conservation and pollution prevention technologies for residential,
commercial, industrial, and utility application

PROGRAM RESOURCES
The erc has a small. dedicated staff. However. to accomplish its mission, the CTC
. .
draws expertise from the staffs of its sponsoring organizations-AEERL and ESD. Additional
resourees and expertise are provided through EP A contractors when appropriate and necessary. This
section addresses the erc's staff resources and contractor budget.
.3.1 STAFF RESOURCES
Each of the sponsoring organizations provides four individuals to support CTC activities.
Although these eight erc staff members are. assigned to the erc, some of their time is allocated to
projects and activities that are part of the sponsoring organizations' missions, but unrelated to the
CTC. It is estimated that the equivalent of 6.6 person years of effort were used to support CTC
activities in FY93. Table 7 indicates the distribution of staff time among the CTC's three major
components.

3.2 PROJEer BUDGET
The erc expended $475,000 on engineering assistance and technical guidance projects during
FY93. This represents a 20 percent decrease from the $592.000 the erc expended on projects in
.
FY92. This amount does not include funding for the Federal SBAP and the RBLC program, each of
which has independent funding.
More than 87 percent of the FY93 expenditures was used to fund technical guidance and
engineering assistance projects. The remaining expenditures covered erc administrative costs, such
as publishing the "erC News," maintaining the erc HOTLINE database, and mailing documents.
The program's FY92 administrative costs did not increase from FY92's $60,000.
The decrease in erc expenditures occulTed mainly because of budgetary considerations at
ESD. Because of a 40 percent overall decrease in ESD's budget and the need to provide initial
funding to the SBAP, ESD's share of erc funding decreased from $450~000 in FY92 to $150,000 in
FY93. This trend in funding is expected to stabilize. Requests for new projects are expected to
increase because of the formation and expansion of the state technology assistance efforts, including
the SBAPs, and the full impact of the 1990 CAAA.
As noted above, the SBAP and RBLC programs are funded under separate allotments not
directly associated with erc funding. The RBLC expended $100,000 in FY93 for maintenance and
improvements. The Federal SBAP is using its $100,000 FY93 budget to develop a small business
bulletin board and to hold a national SBAP conference. The distribution of erc contract resources in
FY93 is indicated in Table 8.

PROGRAM DEVELOPMENT
In FY94, the erc plans to expand its capacity to serve the. needs. of its clients. Based on
three major EPA initiatives-pollution prevention, encouragement of new and innovative technologies.
and cross-media impacts--the expansions planned for erc include the following:
1.
Build pollution prevention capacity within the erc to aid in assisting State
SBAPs and other erc clients. This will be accomplished by modifying the
RBLC to enhance pollution prevention information fields and search
capabilities. developing contacts with other government centers to share
information, and establishing electronic links with existing pollution prevention
centers. .
2.
Expand the erc BBS to include information on new and emerging
technologies (both add-on and pollution prevention). This type of BBS is
being considered as part of the Environmental Tech~ology Initiative (ETI) and
in response to recommendations being developed by the New Source Review
. Reform Workgroup for the RBLC.
3.
Expand efforts to conduct new technology assessment projects in cooperation
with industry. These projects help define the technical and economic
feasibility of new technologies as they relate to the control or elimination of
specific waste/emission streams.
4.
Explore the development of policy. procedures, guidance, and rules
implementing the "cost recovery" provisions of Section 112(1)(3) of the
CAAA. This will give the erc expanded capability to consider and
implement projects requested by the private sector.
5.
Develop capacity to consider cross-media implications of air pollution
control/prevention technology applications.
6.
Establish an SBAP BBS to provide an avenue for state and local SBAPs and
EP A to share materials developed for small businesses.
24
-------
7.
Coordiriate the development of infonnational materials targeted at small
businesses. These materials will explain, in layman's tenns, new regulatory
requirements as well as applicable pollution prevention and control options.
These expansion initiatives represent a plan extending well beyond FY94. However, the CTC
hopes to make significant strides in implementing and attaining these initiatives in the near futUre.

SECTION 5.0
CONCLUSIONS
The erc continued to grow rapidly in FY93. Access to CTC services more than doubled
FY92 activity; that is, 30,765 accesses in FY93 compared to 15,006 accesses in FY92. This growth
was primarily attributable to the tremendous increase in activity by the CTC BBS (91 percent increase)
and especially the RBLC (503 percent increase).
Overall 'erc HOTI.INE activity increased by 22 percent but showed a significant
change in clientele. Private sector, non-governmental agency calls now account for 62 percent of all
HOTI.INE calls. Non-governmental calls increased by 45 percent over FY92 levels, whereas calls
.'
from governmental agencies decreased by 4 percent compared to the same period. Since the passage
of the 1990 CAAA, calls from government agencies have leveled off and remained fairly constant, but
non-governmental calls have risen significantly.
Requests for erc products continued to increase, but at a slower rate than in FY92.
The increase in FY93 was 25 percent compared to a 47 percent increase in FY9~. These figures do
not include products downloaded from the CTC BBS. The popularity and use of the CTC BBS to
obtain' copies of CTC reports and products could account for the lower rate of increase in product
requests. The use of the CTC BBS is being encouraged in order to reduce printing costs and resources
required to handle and mail documents.
Federal SBAP activity is about to explode. Virtually all State SBAPs will become fully
operational in FY94. Work has begun on an SBAP BBS that will provide an avenue for state and
26
-------
local SBAPs and EP A to share materials developed to assist small businesses. The CTClFederal
SBAP will be hosting the fU'St annual Small Business Technical Assistance Conference in January
1994 to initiate coordination and identify program needs and goals. The Leadership Grants Program is
also being established to promote innovative approaches to assisting small businesses.
Dramatic increases in access and -use of CTC services indicate that the CTC is successfully
responding to the ever-increasing demand foro air pollution control infonnation. Hewever, this level of
activity and growth is proving to be a challenge.

"Emissions from Burning Cabinet Making Scraps," EPA-600/R-93-213, PB94-130408
The report gives results of an initial detennination of differences in emissions when burning
ordinary cordwood compared to kitchen cabinet making scraps. The tests were performed in an
instrumented woodstove testing laboratory on a stove that simulated units observed in use at a kitchen
cabinet manufacturer's facility. .
90-7
"Characterization of Emissions from the Simulated Open Burning of Non-metallic Automobile
Shredder Residue," EPA-600/R-93-044, PB93-172914
. The report gives results of a study in which the open combustion of a nonmetallic waste
product called "fluff' was simulated and the resulting emissions collected and characterized to gain
insight into the types and quantities of these air pollutants. The reclamation process for recyclable
ferrous and non-felJ'Ous metals from scrap automobiles generates fluff consisting of a combination of
glass, plastics, rubber, wood products, and electrical wiring. The waste product is often stockpiled or
landfIlled. A number of the stockpiles have caught fire, resulting in the emission of many air
pollutants.
91-8
"Evaluation and Costing of NO" Controls for Existing Utility Boilers jn the NESCAUM
Region," EPA-453/R-92-010, PB93-142016.
This technical report discusses NO" controls for utility boilers in the Northeast Sta,tes for
Coordinated Air Use Management (NESCAUM) region. The document discusses utility boiler
population profIle in the NESCAUM region, uncontrolled NO" emissions and factors that affect NOx
emissions, available NO" controls and their levels of performance, cost methodology for determining
the costs of NO" controls, costs and cost effectiveness of NO" controls, and impacts of NO" controls
on combustible emissions.
..
91-11 "Characterization of Air Emissions from Simulated Open Combustion of Fiberglass Materials,"
EPA-600/R-93-239, PB94-136231
The report identifies and quantifies a broad range of pollutants that are discharged during
small-scale, simulated, open combustion of fiberglass, and reports these emissions relative to the mass
of fiberglass material combusted. Two types of fiberglass materials (representing the boating and
building materials industries) were combusted in a controlled outbuilding designed to simulate open
burning.

"Automobile Assembly Plant Spray Booth Cleaning Emission Reduction Technology,"
EP A-453/R.94.029
Cleaning of automobile spray booths is a source of volatile organic compound (VOC)
emissions. This study was conducted to obtain and evaluate infonnation on: (1) the use of alternative
cleaning practices within the industry that reduce or eliminate the use of organic cleaning solvents, (2)
the current level of VOC emissions resulting from spray booth cleaning, and (3) the emissions
reductions achieved by implementing alternative cleaning practices. Infonnation from 15 automobile
assembly plants operated by eight companies was reviewed, evaluated, and summarized. The
conclusions from this study are: (1) there is significant potential for VOC emissions reductions;
(2) emissions and. thus, potential reductions range from a few tons to nearly 1,000 tons/year per plant;
(3) typical emissions reductions achieved by specific alternatives are less than 20 tons/year but can
range up to nearly 200 tons/year; and (4) elimination of solvent spraying as a cleaning practice. holds
the greatest potential for reducing emissions. .
92-9
"Use of Temporary Enclosure Test Procedure for Polystyrene Foam Blowing"
This project was requested by the U.S. EPA Region 3 to help support an on-going
enforcement action with the Pennsylvania Department of Environmental Resources. The final report
evaluated the potential of using EPA's proposed temporary total enclosure test procedure to determine
emissions from polystyrene blowing processes. It also considered other potential options that could be
used to determine emissions from these processes. Since the final report addressed emissions at a
particular source and contained information claimed as confidential by the source, this report is not
available for public distribution. .
92-13 "Evaluation of the Polyad@ FB Air Purification and Solvent Recovery Process for Styrene
Removal," EPA-600/R-93-212, PB94-130317
."
The report gives results of a study evaluating the Polyad@ fluidized-bed (FB) process for
controlling styrene emissions at a representative fiberglass shower stall and bath tub manufacturing
plant. The process was evaluated using a transportable unit supplied by Weatherly, Inc., of Atlanta,
GA, responsible for domestic marketing and sale of the process. The evaluation was carried out
November 3-5, 1992, at the Eljer Plumbingware facility in Wilson, NC. The Polyad@ FB process uses
beds of macroporous polymer particles as a regenerable adsorbent to capture styrene emissions. The
source tested was a gel coat spray booth exhaust. A side stream from the source was routed to the
pilot unit. and inlet and outlet styrene concentrations were measured using Total Hydrocarbon
Analyzers (THCs) and carbon adsorption tubes (EPA Method 18). The process demonstrated the
capabilities of removing from 94 to 99% of the styrene emissions.
92-15 "Review of HWVP BARer Determination of the Air Emissions and Defense Waste Branch,
Radiation Protection Division. Wash,ington Department of Health,"
P.O. No. 2D3029NASA; GP-R-71193010
This report documents assistance provided to the Washington Department of Health in
evaluating the Hanford Waste Vitrification Plant (HWVP) Best Available Radionuclide Control
Technology (BARCI') demonstration and provides technical comments on the proposed control
technology. Because this effort deals with specific issues in the HWVP BARCT demonstration and
because radioactive waste vitrification is not a topic of general interest, the CTC decided not to
publish this document; however. the erc may make copies available on an as needed basis.

The information has been obtained from available literature, information provided through Federal,
State. and local air pollution control agencies, and information obtained from the leather tanning and
finishing measures to control volatile organic compound (VOC) emissions from leather tanning an~
finishing facilities. It also provides a general description of the industry; describes the key processes
employed in manufacturing leather; characterizes the emissions of VOCs and HAPs from the industry;
describes applicable emission reduction technologies; and finally, discusses current State and local air
pollution regulations affecting the industry.
92-17 "Evaluation of Mercury Emissions from Fluorescent Lamp Crushing," EPA-453/R-94-018
The CTC assisted the Florida DNR in evaluating potential mercury emissions and potential
control techniques for a process that crushes/recycles fluorescent lighting tubes. The project involved
reviewing the sources permit application, information gathering, an evaluation of the emission potential
of this source, and the identification and evaluation of potential mercury emission control techniques.
93-3
"Initial 'Assessment of Emissions from Heat Setting Carpet Yam," EPA-600/R-93-161,
PB93-229862
The report gives initial results of a project to determine the nature of emissions resulting from'
the heat setting of carpet yam and to identify possible control options. To collect the necessary
technical information, two manufacturing facilities were visited: World Carpets in Dalton, GA (a yam
and carpet manufacturing facility) and Diamond Mills in Rome, GA (a yam spinning facility).
Information on the yam spinning and heat setting operations was gathered, the carpet manufacturing
process was viewed, and (with input from the plant technical staff) opportunities were identified for
preventing andlor controlling the heat setting emissions.
93-5
"HAP-PRO Carbon Absorber Module Improvements"
The carbon absorber module has been rewritten to include an "expert" system to assist and
check the solutions provided. It is available on the CTC BBS.
93-11 "Oil Suppression of PM at Grain Elevators"
At the request of and in cooperation with the Nebraska DEC, the CTC conducted a project to
evaluate oil suppression to control particulate emissions from grain elevators; however, Nebraska was
not able to coordinate testing of this technology needed to verify its effectiveness. Although the final
report cited information that suggested that oil suppression was a practical and cost-effective
technology, this information was inconclusive. The CTC is withholding the release of this report
while alternatives for conducting the needed tests are being considered.
