During the 1950's, the development
of nuclear power preoccupied Federal
energy programs. Official policy was
based on the belief that nuclear power
would someday displace petroleum
and natural gas as the nation's main
source of electricity generation. The
clean fossil fuels, it was thought,
would continue to be in abundant
supply for transportation, home
heating and other uses. Nuclear
power research received greater
emphasis and funding as the
interest in coal research waned.
Simultaneously, the production of oil
and natural gas increased while
mining of coal declined.
  In the 19601s, the White House
commissioned the first compre-
hensive review of the nation's
future energy problems. Known as the
Cambel Report, the review embodied
the accepted belief in the two fuels
concept—nuclear fuel for electricity,
and petroleum fuel for transportation.
  The 1970's were characterized by
major legislation aimed at reversing
the trend toward environmental
degradation associated with effluents
and emissions from energy and
industrial sources. The Clean Air Act,
the Federal Water Pollution Control
Act,  and the Resource Conservation
and Recovery Act have had major
impacts on existing and new energy
facilities. They have required
incorporation of state-of-the-art
control technology to minimize air,
water and land pollution and have
encouraged development of more
effective and less costly controls in
order to improve environmental quality
"We can elect to pay the
   environmental and
public health costs with
advanced cost-effective
control technologies,  or
      burden future
  generations with far
        higher  costs."
                   Steven R. Reznek
       Deputy Assistant Administrator
                            OEET
  By 1967 the White House
questioned energy complacency and
established an Energy Policy Office
within the Office of Science and
Technology. In 1971, the President
delivered the first energy message,
calling for development of flue gas
desulfurization technologies and
production of synthetic high-BTU gas.
Both programs were aimed at finding
ways to make coal a more acceptable
fuel. By 1972, national science policy
makers began to question the
conventional wisdom on our future
fuels availability. A new study was
ordered by the administration to
develop a set of energy research and
development goals. Before that study
could be disseminated, the Arab
world imposed the historic oil
embargo  of 1973-74.
  Following the embargo, the
President commissioned a Federal
study of energy problems and needed
research programs. That study, "The
Nation's Energy Future" —better
known as the Ray Report — stated
two things quite clearly: first, the cost
of new energy supplies would be
high; energy supply must cease to be
regarded as a public service delivered
to meet any and all demands; the
amount of energy supplied must
reflect its cost of production. Second,
available sources of new energy had
the potential for degrading
environmental quality and impairing
public health; proper choices of future
energy supplies therefore, must
include an evaluation of their potential
impact on human health and the
environment.
  Based on recommendations of the
Ray Report, the Office of Management
and Budget (OMB) proposed a
program to develop new and
environmentally acceptable
nonnuclear energy sources. The
fundamental legislation for this
program was the Federal Nonnuclear
Energy Research and Development
Act (Public Law 93-577 enacted in
December, 1974) and the agency
designated to implement the Act was
the new Energy Research and
Development Administration (ERDA).
Section 11 of PL. 93-577 directed the
President's Council on Environmental
Quality to hold annual public hearings
and prepare appropriate reports on
"... the adequacy of attention given to
energy conservation methods and
environmental protection... and the
environmental consequences of the
application of energy technologies."
(Responsibility for this review was
subsequently transferred, under
President Carter's reorganization in
1976, to EPA.)

-------
Interagency R&D Program
The President's Council on
Environmental Quality and the Office
of Management and Budget estab-
lished two Federal interagency task
forces representing 23 Federal agencies
and departments to ensure that major
environmental problems related to
energy resource development were
anticipated and evaluated. One of
these task forces designed a program
for controlling energy pollutants and
impacts. The other designed a
program for research on environmental
processes and effects of energy
development. They jointly developed a
program structure for the Federal
Interagency Energy/Environment
Research and Development
Program with its  two main R&D
areas:
    •  The Control Technology
       Program, and
    •  The Health and Environmental
       Effects  Program.
The environmental control technology
portion of the Interagency Program is
administered by EPA!s Office of
Environmental Engineering and
Technology (OEET) within the Office of
Research and Development.
  At the time of the Arab oil
embargo, EPA maintained a program
in pollution control technology for
combustion sources. For stationary
sources, this program included the
control of sulfur oxides, nitrogen
oxides and particulate matter. For
mobile sources, the program was
designed to develop alternative, less
polluting power systems. With the
enactment of P.L. 93-577, the division
of responsibility between EPA and
ERDA for energy/environment
research was made clear. ERDA would
develop all new energy technologies
and be responsible for their
environmental performance. EPA
would develop  controls for
conventional energy technologies and
assess the environmental performance
of conventional and advanced energy
technologies. These  defined
responsibilities remained effective
until Fiscal Year 1979, at which time the
Department of Energy, whose role is to
oversee large-scale demonstration
projects, joined in the program to
develop controls for conventional
combustion sources.
  Ibday, EPA and DOE cooperate in
the planning, review and
implementation of the control
technology program, which has three
major types of activities:
    • Environmental assessment,
    • Regulatory support, and
    • Environmental control
      technology development.
  Environmental assessment is the
process of identifying the types or
quantities of pollutants or
environmental impacts from energy
technologies. The purpose of
assessment is to identify
environmental concerns and to set
priorities for establishing control
requirements. Regulatory support
involves the development of
information bases for establishing
control requirements under the Clean
Air Act, the Clean Water Act, the
Resource Conservation and Recovery
Act and the Ibxic Substances Control
Act. Finally, environmental control
technology development includes
research and development of
laboratory techniques, pilot plants and
demonstration facilities for new
pollution control systems.
  One important aspect of this control
technology program is the review,
evaluation and the subsequent
dissemination of the results to those
in the Federal research community,
both within and outside the
interagency program, and to other
individuals and organizations who are
involved in related work.
  The goal of EPA's energy/
environment program today is
to assure that the nation can
accomplish the transition from over-
dependence on oil and gas to  greater
use of abundant domestic coal
resources and other alternative fuels,
without undue degradation of the
environment. This means, in essence,
that the costs and capabilities of
environmental pollution controls must
be better understood and new
technologies must be designed and
operated to minimize pollution. This
program can help solve the nation's
energy problems by ensuring that
environmental problems associated

The Future Challenge
The President has proposed a
comprehensive and aggressive
program to limit the import and
reduce our dependency on foreign oil
and provide the Nation a measure of
energy security.
           The program emphasizes exploration,
           development and use of domestic
           energy supplies - particularly coal, oil
           shale, unconventional natural gas and
           heavy oil. Energy conservation
           measures, related to automobile use
           and home and office heating and
           cooling, are strongly encouraged.
             Assuming that these proposed
           conservation and production
           initiatives are successful, projections
           indicate a massive increase in
           coal mining and use, as well as
           major growth in other fossil energy
           sources. Coal mining in the United
           States will increase from the current
           700 million tons annually to 1.4 billion
                        tons in 1990 and 1.9 billion tons
                        by the end of the century.
                        Although most of this growth in coal
                        use is associated with conventional
                        combustion, 120 million tons are
                        projected to be used for the
                        production of synthetic liquids and
                        gases in 1990 and 300 million tons in
                        2000. We can also expect that the
                        1980's will see the oil shale industry
                        emerge as a significant supplier of
                        fuel, producing up to 40,000 barrels
                        per day by 1990 and 1.2 million barrels
                        per day by 2000.
                          Such projections indicate a trend
                        away from traditional and less
                        environmentally damaging energy
                        sources, toward potentially more
                        damaging fossil fuel sources such as
                        coal, oil or gas from the Outer
                        Continental Shelf, and western oil
                        shales.

-------
   These major shifts toward increased
 use of fossil fuels can pose a
 significant threat to human health
 and the environment. Potential
 negative impacts are likely to result
 from the extraction, processing and
 utilization phases of each major fuel.
 For example, increases in coal and oil
 shale mining can create erosion and
 subsequent surface water siltation
 problems;  groundwater quantity and
 quality are also likely to be affected.
 Processing coal and oil shale to
 synthetic liquids and gases may yield
 toxic emissons and, despite current
 regulations, an increase in coal
 combustion will result in increased
 production of nitrogen oxides, sulfur
 oxides and solid wastes.
   Many of the adverse impacts on
 health and environmental quality can
 be controlled or avoided: most mined
 land can be reclaimed; particulate
 matter and the oxides of nitrogen and
 sulfur can  be scrubbed from flue gas;
 acid precipitation and its effects on
 agricultural and forest production can
 be reduced.
   Controlling these pollutants
 increases the monetary cost of energy,
 but failure to control them lowers the
 productivity of our natural resources,
 degrades the quality of our
 environment, and imperils the health
'of our population. We can elect to pay
 the environmental and public health
 costs of increased use of fossil fuels
 now with improved reclamation
 practices and advanced cost-effective
 control technologies, or we  can
 burden future generations with the far
 higher costs of a barren planet whose
 air, water, land, and human  resources
 have been dissipated.

-------
The overall objective of EPAs energy/
environmental control technology
program is to provide the scientific
information necessary for developing
rational policies that strike a
balance between ample Quantities
of affordable domestic energy and
environmental quality In order to
achieve this objective, the Agency is
conducting, in conjunction with other
Federal agencies, a comprehensive
research, development and
demonstration program focused on
evaluating and developing cost-effective
pollution control technology. The major
thrust of the program is to generate
technical and cost information on
which reasonable environmental
standards  can be based.
Scope
In light of the potential increases in
coal use for conventional combustion
and synthetic fuel production, and the
emergence of oil shale and offshore oil
as major liquid fuel sources, the EPA
control technology program is focused
on the following areas of energy
research:
    • Extraction of coal, oil shale and
      offshore oil;
    • Fuel processing, with emphasis
      on synthetic fuels from coal, oil
      shale  and biomass; and
    • Coal combustion, with
      emphasis on sulfur oxides
      (SOx), nitrogen oxides (NOx),
      particulates, unregulated
      pollutants, ashes and sludges;
    • Other emerging energy
      technologies, particularly
      geothermal, waste-as-fuel and
      solar technologies.
  "OEET is developing
          advanced
       environmental
   control technologies
          to provide
      an energy-secure
            economy
  and a healthy human
        environment."
                   Frank T. Princiotta
     Director, Energy Processes Division
                              OEET
  The control technology program is
comprised of six subprograms:
Fuel Extraction. This program deals
with environmental quality problems
associated with the technologies and
processes for obtaining fuels, such as
offshore oil or natural gas extraction, oil
shale development, or coal mining. It is
intended that this research program (1)
assess the existing and potential
adverse environmental impacts from
active and future resource extraction,
production, storage and transportation,
(2) develop methods,  technologies and
equipment to prevent, control, and
abate  environmental pollutants from
these  operations (including spill
clean-up), and (3) document the
technical/operational feasibility and
cost effectiveness of environmental
control options.
Fuel Processing,  Preparation and
Advanced Combustion. This
program is involved with the
development of advanced technologies
for fossil fuel processing by providing
environmental assessments,
bench-scale research, technology
 assessments and guidance in process
 control technology. The program will tie
 in with DOE's process development and
 environmental programs to identify and
 quantify all residuals from synthetic
 fuels from coal processes, oil shale
 development, fluidized bed combustors,
 and coal cleaning. Comprehensive
 environmental assessments will be
 performed for these technologies to
 anticipate the severity of each
 environmental problem and the
 corresponding means for its control.
 Flue Gas Sulfur Oxide Control. This
 program develops and evaluates
 alternative technologies for the removal
 of sulfur oxide emissions from
 combustion flue gas. The goal of this
 program is to develop technical data on
 which EPA may establish emission
 standards for sulfur-emitting sources.
 Efforts are underway to evaluate
 existing sulfur oxides removal
 installations and to assess other
 impacts of flue gas desulfurization
 (FGD) technology and the applicability
 of FGD technology to industrial boilers
 and other sulfur oxide sources.
 Nitrogen Oxide (NOX) Control. The
 objective of this program is to develop
 the best practicable combustion
technology for the control of NOX
 emissions from the leading categories of
 stationary sources including utility
boilers, commercial/industrial boilers,
residential heating systems, stationary
engines, and advanced combustion
processes. Advanced combustion
 processes such as staged coal
burners and coal burner systems are
being studied and fundamental
engineering and analytical support
studies are also being conducted to
evaluate the potential of these

-------
advanced methods of NOX emission
control and energy conservation. Major
emphasis is being placed on developing
and demonstrating low NOX burners for
new and existing utility and industrial
boilers.
Flue Gas Particulate Control. This
program identifies and develops
effective practicable technology to
control aerosol emissions from
man-made sources. Source  categories
addressed include utility and industrial
coal combustion. Major research efforts
in the program are: assessment and
extension of the capability of
conventional systems (electrostatic
precipitators, scrubbers, or fabric filters)
for abating aerosol emission; exploration
of new and improved methods of
control; and bench-scale investigation
of specific control methods for major
problem sources including low-sulfur
coal combustion, new fuels, power
production, and selected industrial
processes.
Environmental Impacts of Con-
ventional and Advanced Energy
Systems. This program includes en-
vironmental assessment and toxic pol-
lutant control technology development
for coal and oil combustion facilities,
from residential furnaces to utility
boilers; advanced energy systems,
such as geothermal and solar, and
conservation technologies, particularly
waste-as-fuel operations. Emphasis is
placed on unregulated pollutants such
as polycyclical organic materials, trace
elements, sulfur compounds, and
ashes and sludges. The program also
provides analysis of environmental,
economic, and social impacts of
alternative energy supply and use
patterns on both a regional and na-
tional level.

R&D Management
The Office of Research and Devel-
opment (ORD) has made a major
commitment over the last several
years to upgrade the relevance, im-
pact and quality of EPA's research
program. Particular emphasis has
been placed on assuring that the
research program is  focusing on im-
portant Agency regulatory and en-
forcement issues. Toward this goal,
ORD has instituted twelve research
committees comprised of ORD and
Program Office representatives who
are involved in' developing the re-
search program. ORD's Office of En-
vironmental Engineering and Technol-
ogy supports the research committee
approach and also maintains close
communications with EPA's regulatory
offices.
  In order to manage the energy
program effectively, ensuring that it is
responsive to the Agency needs, ORD
has instituted a management system
that identifies major OEET research
projects and places them in one of
three categories. Category I desig-
nates projects in direct response to
near term  and specifically scheduled
Program Office needs. Category n
projects are desired by the Program
Office but  are not required by a
regulatory schedule. Category HI proj-
ects are of interest to one or more
Program Offices, but are usually de-
signed to anticipate a regulatory re-
quirement and are motivated by re-
search interests.
  EPA is also establishing a Synfuels
Steering Committee, co-chaired by
ORD and the Office of Planning and
Management, whose responsibility
will be to coordinate all research and
regulatory activities relating to
synthetic fuels. The day-to-day
functioning of this committee will
help assure the relevance of the
energy program to EPA's mission.
  The Office of Environmental
Engineering and Technology
recognizes that energy research
results are not only important within
the Agency, but are also important to
potential users outside the Agency.
These others users may include
energy facility designers and
operators, state and local government
environmental officials, control
technology firms and other research
organizations, such as DOE, the TVA
and the Electric Power Research
Institute. The Office of Environmental
Engineering and Technology is
conducting an agressive information
and technology transfer program to
reach these important groups.  The
program sponsors internationally-
recognized symposia, in selected
technology areas, where federal and
other researchers may present
their results to others. Among
the major, regularly scheduled
conferences are the Flue Gas
Desulfurization Symposium,
Stationary Source Combustion
Symposium, Symposium on Transfer
and Utilization of Particulate Control
Technology and the Conference on the
Environmental Impact of Fuel
Conversion.  The  Energy/Environment
R&D Decision Series reports are
another approach utilized for
technology transfer. The Decision
Series, inaugurated in 1976, presents,
in an  easily understood and concise
manner, key issues and findings of the
research program.

Interagency Coordination
Since the program's inception, EPA
has maintained a close working
relationship with other Federal
Agencies involved in energy-related
research. In fact EPA often funds other
agencies when their expertise or
unique facilities enable them to
perform the required research,
development or demonstrations more
effectively. Major partners in these
"pass-through" efforts have been the
   Tennessee Valley Authority in the flue
   gas desulfurization (FGD) area, the
   Department of Interior in mining and
   coal cleaning, and the Department of
   Energy in the assessment of synfuel
   processes. Efforts to work even more
   closely with DOE have intensified
   over the last year since DOE
   embarked on a large coal combustion
   control technology program.
                                                                                                                            11

  In order to best use the resources
available for the development of
economical and reliable coal
combustion pollution control
technology a cooperative planning
and review system has been formed
to support the objectives of the joint
EPA/DOE program. The two agencies
have agreed on two broad goals to
guide their efforts:
     •  Support the increased use of
       coal, as specified in the
       National Energy Act.
     •  Ensure that coal use is
       managed in a manner that will
       protect public health and the
       environment.
  To fulfill these goals, EPA and DOE
have developed a set of specific
objectives for their cooperative effort:
first, improve the reliability and
performance of available
environmental control technologies for
use by electric utilities and industry;
second, reduce the capital -and annual
costs associated with environmental
control; and third, develop and
demonstrate methods of disposing of,
or using, solid waste created by coal
use.
  The joint planning arrangement is
formulated in a proposed Cooperative
Agreement whose  goals are to
coordinate interagency activities,
maintain interagency cooperation in
areas of mutual interest,  and
formulate an overall management
structure for implementing joint goals.
Provisions include  semi-annual
reviews of the cooperative program
and mechanisms for the transfer of
funds between the agencies.
  Not all of the non-nuclear research
and development is supported by
Federal organizations. Private

Funding
The accompanying table summarizes
program funding, by subprogram
area, for Fiscal Years 1979 and 1980.
It also indicates FY 79 "pass-through"
funding from DOE and DOI to EPA.
  In Fiscal Year 1979, DOE funded
$3.4 million in the coal combustion,
fuel processing and environmental
assessment areas, and DOI funded
$500 thousand toward an EPA/DOI
project that evaluated the
environmental effectiveness of selected
mining reclamation techniques.

Program Highlights
The energy control technology
program has been and will continue to
be unusually productive in terms of
generating information that makes a
significant positive impact on
environmental quality. The program
has improved the quality of data used
in Agency decisions and has affected
the types of equipment and
performance of commercial pollution
control systems.
  Several on-going or recently
completed activities have made or
have the potential to make a
significant impact on the goal of
environmental quality with acceptable
cost. These activities may:
    • Support EPA's  program offices
      directly,
    • Advance the state-of-the-art
      for commercial control
      technology, or
    • Define control requirements by
      the types and  quantities of
      pollutants or environmental
      impacts (environmental
      assessments).
                                                                                                             13

Selected projects highlighting direct
support of EPA program offices are
described below:
Coal Ash And Sludge Disposal.
Information has been compiled to
establish economically achievable
guidelines or regulations for the
disposal of ashes and sludges from
coal-fired power plants and non-coal
mining wastes.
Synfuel Pollution Control Guidance
Documents. Pollution control
guidance documents are being
prepared for the emerging synthetic
fuels industries, e.g., oil shale, coal
liquefaction and gasification, and
ethanol from biomass. These
documents will provide engineering
and cost data for the issuance of
permits and will provide background
information and the development
documents needed for the
promulgation of technology-based
regulations.
Offshore Oil & Gas Effluents. EPA
is currently producing an information
document dealing with the effluent
characteristics of discharges from
offshore oil and gas production
facilities.
Utility and Industrial NSPS
Support. Data, technology
assessments and economic impact
 analyses are being provided to the
 Office of Air Programs to allow them
 to establish New Source Performance
 Standard (NSPS) for the electric utility
 industry and for industrial steam
 production which are economically
 and reliably achievable.
 Inhalable Particulate
 Characterization. The program is
 characterizing inhalable particulate
 matter emissions from major energy
 and industrial sources.  This
 information will be required to allow
 selection of the most economical
 control strategies to achieve a
 possible inhalable or fine particulate
 ambient standard.
 Stationary Gas Turbine NSPS
 Support. A new, low-cost,
 energy-efficient technique to lower
 NOX emissions  from stationary gas
 turbines has been developed. This
 Technology, known as "dry NOX
 control," can lower oil consumption by
 about 3 percent while complying with
 existing emissions regulations.
  Typical of the program's activities
 designed to advance the
 state-of-the-art  of environmental
 control technologies are the following:
 Particle Precharger. EPA is currently
 developing and testing, at pilot scale,
 an advanced electrostatic precipitator
 which includes  a precharger stage
that holds promise of greatly reducing
the cost of particulate control for
 coal-fired boilers. Such a device is
particularly attractive for low-sulfur
 coal applications where the ash's
electrical properties lead to a
requirement for  a large and costly
precipitator.
 Low-Nox Coal Burner. EPA
 developed a low NOX coal burner,
 which can lower NOX emissions rates
 by a factor of 4 while maintaining or
 improving fuel efficiency. The new
 burner is of very low cost. Full-scaled
 demonstrations on two
 industrial-sized boilers will begin in
 1980. A demonstration on one 300
 MWe utility-scale boiler will begin in
 1981.
 Dry SO2 Control. Research and
 Development is leading to the
 application of dry SO2 control
 technologies to industrial and
 utility-scale  boilers. Dry S02 control
 appears to offer substantial
 reductions, about 30-70 percent, in
 capital and annual revenue
 requirements while achieving levels of
 SO, reduction comparable to
 conventional wet scrubbers. Three
 different approaches  are being
 pursued: post combustion spray dryer
 SO2 control technology,  coal/limestone
 pellets, and  simultaneous
 limestone/injection coal combustion
 in the low NOX burner.
 Additives for Improved SO2
 Control. Chemical additives are
 being tested to improve flue gas
 desulfurization (FGD) reliability and to
 lower costs.Additives, such as adipic
 acid, can improve the operational
 reliability of utility scale FGD systems
 by eliminating the effects of sudden
 changes in coal sulfur content or
 equipment variability on FGD
 performance. These additives will
 lower the amount of limestone
 required to remove SO2. The use of
 adipic acid in conjunction with forced
 oxidation of scrubber sludge to
 gypsum can yield a solid waste which
is easier and cheaper to dispose than
conventional lime/limestone scrubber
sludge.

Residential Oil Furnace. EPA is
completing the evaluation of a new,
EPA-developed residential oil
furnace. This furnace, which has
undergone two years of testing in
New York and Massachusetts, could
lower fuel costs by an average of 18
percent. Improving fuel utilization
while simultaneously lowering NOX,
soot, and hydrocarbon emissions,
demonstrates that effective
environmental control can be
achieved without increasing costs.
  The following brief descriptions
highlight program activities related to
environmental assessment:
Emissions/Effluents From Coal and
Oil Shale Synfuel Processes. A
comprehensive environmental
assessment program has been
conducted over the last three
years. The program is aimed at
characterizing emissions/effluents
and control options for processes
producing synthetic fuels from coal.
This program has allowed
prioritization of waste streams for
their potential environmental impact
based on their potential for health and
ecological damage.
Fundamental Combusion
Phenomena. Fundamental
combustion phenomena which yield
SOg, Nox, soot and polynuclear
aromatic hydrocarbons have been
investigated to determine more
effective ways of controlling these
pollutants prior to their formation.
Emission/Effluents From
Emerging Non-Fossil Fuel
Facilities. Potential, environmentally
damaging non-fossil fuel energy
technologies are being assessed;
prominent are geothermal and
waste-as-fuel operations.
                                                                                                            15

                                       For many decades, this country
                                       experienced plentiful and inexpensive
                                       energy supplies. The cost of energy
                                       decreased, due in part from expanded
                                       discoveries of easily obtainable fuel,
                                       in part from  technological innovation,
                                       and in part from investments
                                       in the production  and transportation
                                       eeniipment capital necessary to make
                                       energy delivery efficient.
                                         The first 74 years of this  century
                                       saw investments of capital and labor
                                       returning increased amounts of useful
                                       energy in the form of electricity, home
                                       heat, and transportation fuel. Today,
                                       however, the cost of new energy
                                       sources is increasing, and we wiH use
                                       increasing amounts of our productive
                                       capacity to obtain decreasing
                                       amounts of energy The challenge will
                                       be to stimulate investment in these
                                       high-cost/low-yield techniques.
  The present situation has created
remarkably difficult problems for our
economic and social systems which
are unique to a hitherto vigorously
expanding country. As a society, we
have found it enormously difficult to
accept the fact that inexpensive fuels
are disappearing and that we must
now not only pay more, but use less.
Foreign or domestic oil interests may
exploit the situation to realize large
profits, but this does not deny the
fundamental reality—the American
people will have to pay more for their
energy and use less. The nation must
change from a society oriented to
resource exploitation to one oriented
to resource conservation.
  We are currently embarked on an
energy path that will require, along
with conservation, the continuing
expansion of our domestic energy
resources and exploration of new
sources. Many of these fuels will be
more difficult to extract,  and wiH be
"dirtier" to use. But  the hazards to
human health and to the environment
can.be avoided, through the vigorous
development and capital investment
in pollution control systems. The EPA
Office of Environmental Engineering
and Technology is pursuing just such
a program to develop advanced
cost-effective environmental control
technologies, which will allow this
nation an energy secure economy and
a healthy human environment.
