The 33/50 Challenge
Susan Hazen, Director
Special Projects Office
EPA's Office of Toxic Substances
EPA's 33/50 Program is off to an auspi-
cious start. The program aims at achieving a
50 percent reduction by 1995 (with an
interim reduction of 33 percent by 1992) in
chemical wastes reported to the Toxics
Release Inventory. The challenge will be in
achieving these reductions through pollu-
tion prevention and through voluntary
commitments from industry, rather than
through regulations. But there is a growing
assurance that the program can work.
Everything we have seen so far convinces
me that voluntary reductions can bring
about great environmental benefits and a
strengthened role for workers and commu-
nities, while leaving industry the maximum
amount of flexibility for implementing
solutions.
Even before asking for industry responses
to the 33/50 Program, we received almost
100 enthusiastic letters from companies.
Listen to what they have to say:
Hewlett -Packard Company:
Voluntary efforts led by EPA... have great
potential for realizing significant reductions in
chemical emissions nationwide.

EPA, USDA to Fund Joint Grant Fool
$2 million for sustainable agriculture projects available under joint agreement
EPA and the U.S. Department of Agricul-
ture (USDA) have joined forces in one of the
first cross-Agency cooperative grant
programs in the federal government.
In FY 1991, the Office of Pollution
Prevention at EPA and the Sustainable
Agriculture Research and Education
Program (previously known as the Low-
Impact Sustainable Agriculture (LISA)
program) of the USDA Cooperative State
Research Service will distribute grants from
a $2 million joint pool to fund projects
involving education, demonstrations,
research on reducing impacts on wildlife
and fish habitat, and studies of economic
implications of sustainable agriculture.
Host institutions in four regions of the
country (northeast, south, north central, and
west) are managing the evaluation, project
selection, and distribution processes for their
regions. Evaluation panels include repre-
sentatives from government, academic and
other research institutions, farmers, the
environmental community, and other
private or public organizations.
Highest priority is being given to inte-
grated systems projects, which functionally
integrate the findings of many research
studies and direct experience into a manage-
rial (whole-farm) or natural system context.
A whole-farm type of study includes
estimation of the overall performance of
alternative farming systems. Natural system
projects are integrated systems studies that
increase understanding of the interactions

Reports from EPA Offices
Enforcement Policies Encourage Settlements Tied to Prevention
EPA's Office of Enforcement has
issued a policy statement that strongly
encourages Agency negotiators to try to
incorporate pollution prevention
conditions in single and multi-media
settlements when feasible. The policy,
effective immediately, is applicable to
both civil and criminal enforcement
settlements involving private entities,
federal facilities, and municipalities.
However, the policy notes that respon-
dents will not be granted additional
time to correct a violation in exchange
for conduct of a supplemental environ-
mental project, although some flexibility
may exist if the pollution prevention
activity represents the means of correct-
ing the violation.
Among the types of situations which
favor the use of pollution prevention
conditions in enforcement settlements
are: recurring patterns of violations
which are unlikely to be corrected by
additional controls; proposed solutions
which do not create environmental
problems in other media; effluent
emissions or discharges for which
feasible prevention options exist; and
violations involving one or more of the
17 target pollutants in EPA's "33/50"
Industrial Toxics Project.
EPA's enforcement program is also
implementing the Administrator's goal
that 25 percent of EPA's enforcement
actions incorporate elements involving
more than one environmental medium
(e.g., surface water and air). The move-
ment towards a multi-media approach to
enforcement is intended to further
Agency objectives of greater environmen-
tal protection, risk reduction, and pollu-
tion prevention, as well as greater deter-
rence, and greater resource efficiency than
a single program/single medium ap-
proach can accomplish.

Rosenberg, 202-475-8869.
New York, New Jersey Enforcement Actions
Use Pollution Prevention Approach
EPA is incorporating pollution
prevention projects into many of its
settlements with firms violating Section
313 of the Emergency Planning and
Community Right-to-Know Act. A
number of recent consent agreements in
Region 2 require firms to make "envi-
ronmentally beneficial expenditures,"
often exceeding the cost of the proposed
penalty, and resulting in more perma-
nent environmental improvements.
Recent examples: EPA Region 2
settled a case with C.H. Thompson in
which the company will install a thinner
recycling unit to recapture toluene and
MEK. Installation of the unit reduces the
amount of thinner disposed of by about
80 gallons per month. At both Northern
Plastics Corporation and Atlas Plastics,
Inc. in New York State, acetone recovery
systems are being installed to reduce the
amount of acetone used and emitted by
the facilities. A solvent recovery system
is also being installed at Colorama
Laminating and Printing, Inc. in New
Jersey. Itran Corporation has agreed to
a partial substitution of liquid nitrogen
for methylene chloride in its processes
that involve removing rubber from
metal.

Similar letters of enthusiastic support
have come in from more than half the
nation's Governors.
Of course, we still have a long way to
go in reaching out to — and getting
responses from — the more than 3,500
companies that report to the Toxics
Release Inventory one or more of the 17
chemicals covered by the 33/50 Pro-
gram. And reduction commitments are
not the same as actual reductions. The
33/50 Program will carefully track
progress towards meeting the 1995
reduction goals, with a particular eye
towards evaluating the overall contribu-
tion of pollution prevention.
As the 33/50 Program takes shape,
we look forward to reporting our
progress to you regularly in these pages.

among living organisms, environmental
conditions, and farming practices.
The program will also give prefer-
ence to proposals for projects that
involve interdisciplinary cooperation,
involvement of both research and
educational activities, and cooperation
with farmers or grower organizations,
non-profit organizations, and private
enterprises involved in sustainable
agriculture research and education.
Special consideration will also be
given to projects in which farmers
actively participate in the design and
implementation.
Awards will be announced in June.

Great Lakes Pollution Prevention Plan Announced
EPA has announced a pollution
prevention action plan for the
Great Lakes region, focused on
reducing the levels of persistent toxic
substances in the Lakes. Holding
approximately 20 percent of the world's
supply of fresh surface water, the Great
Lakes have been termed a "national
treasure" by EPA's Administrator, and
cleaning up the Great Lakes has been
declared one of EPA's top priorities.
EPA is launching four major new
initiatives with the Great Lakes states,
which address the broad spectrum of
pollution prevention opportunities
available in the Basin:
1.	A public/private initiative with
Chrysler, Ford, and General Motors
in a basin-wide effort to identify
persistent toxics of greatest concern,
explore prevention opportunities,
and participate in technology transfer
forums to share information on
prevention techniques and successes.
2.	A cooperative effort on the part of
EPA, Minnesota, Wisconsin, and
Michigan focusing on Lake Superior,
the largest of the Great Lakes and the
most vulnerable to pollution from
toxic substances. The effort will build
on and strengthen existing environ-
mental protection programs, moni-
toring networks, and inspection
activities.
3.	Pilot programs in pollution preven-
tion for urban non-point sources.
EPA will work with New York State
and local governments on projects to
educate consumers on household
hazardous waste and lawn manage-
ment practices, and in helping small
towns to identify and reduce non-
point source discharges.
4.	EPA and Environment Canada will
co-sponsor an International Pollution
Prevention Symposium to be held in
conjunction with the International
Joint Commission meeting in the fall
of 1991 to assess progress and
establish an agenda for future
pollution prevention efforts.
CANADA
Pollution prevention activities will be
targeted by pollutant, source, and
geographic area in order to achieve
demonstrable environmental benefits.
Prime target areas for pollution preven-
tion activities will be Northwest Indi-
ana, the Niagara River, and Milwaukee,
Wisconsin. Targeted pollutants will
include many of the toxic substances
identified in the national 33/50 Program
as well as other critical pollutants of
concern to each lake. Consistent with
the 33/50 Program, the action plan for
the Great Lakes also sets as a primary
goal, a 33 percent reduction of releases
of targeted contaminants into all media
by the end of 1992, and a 50 percent
reduction by the end of 1995.
EPA also expects to conduct a
pollution prevention outreach program
— the "Great Lakes Pollution Preven-
tion Challenge" — to all sectors of
society. Specifically, in launching this
effort, EPA and the states will challenge:
industrial generators in the Great Lakes
basin; agricultural generators; colleges
and universities; federal and state
governments; cities, counties, and
towns; environmental groups; and
individual consumers.
Current Status of Great Lakes
The notorious eutrophication prob-
lems of the Great Lakes have been
greatly reduced over the last two
decades — chiefly through massive
spending on sewage treatment which
successfully reduced nutrient loadings.
However, the presence of persistent
toxic substances in Great Lakes waters
and sediments remains a thorny
problem. Of 43 defined Areas of
Concern in the Great Lakes, 41 show
serious contamination of sediments with
metals and organic compounds.
A cause for continuing concern is the
bioaccumulation and biomagnification
of toxic risks through the food chain.
While concentrations of chemicals
measured in Great Lakes water may be
below detection limits, because of
biomagnification in the food chain, a
chemical can accumulate in the tissue of
fish and other predators, to astonish-
ingly high levels.
Residents in Great Lakes states are
still advised to limit or in some cases
avoid consumption of popular
sportfishing species, such as lake trout
and Great Lakes salmon, due to their
accumulation of toxics. A 1989 study by
the Conservation Foundation in Wash-
ington and the Institute for Research on
Public Policy in Ottawa examined
animal and wildlife studies conducted
over several decades in the Great Lakes
and found striking patterns of toxic
accumulation, with accompanying
health anomalies occurring across a
wide range of species, particularly
including reproductive and generational
effects in animals high in the food chain.
Particularly troublesome is the
realization that airborne deposition of
pollutants is a a major source of con-
tamination of the Great Lakes. Toxic
contaminants can travel hundreds or
thousands of miles on air currents;
much of the DDT (banned in the United
States and Canada) now entering the
Great Lakes is believed to come from
Central America and Mexico. Airborne
deposition indicates the need for
national and international solutions to
pollution problems.
Recent recommendations to the
International Joint Commission point to
the use of wildlife health as indicators of
the overall health of the Great Lakes
ecosystem. In particular, the bald eagle
may be a useful indicator species
because it sits at the top of the Great
Lakes food web and is so sensitive to
ecological disturbances. Thus a flour-
ishing bald eagle population around the
Great Lakes could signal a restoration of
the integrity of the entire ecosystem. ~

Nonprofits' New York Offices Showcase Non-Toxic Design
The New York headquarters of the
Environmental Defense Fund (EDF) and
the Natural Resources Defense Council
(NRDC) are two leading examples of
designing with the environment in
mind.
In renovating the EDF offices,
architect William McDonough at-
tempted to get rid of indoor air pollu-
tion at its source. He made sure the
space had windows that open, refur-
bished the air conditioning system for
maximum ventilation, and provided 30
cubic feet of fresh air per person, per
minute, six times the national standard.
Plywood and particle board were
replaced with solid wood to curb
emissions of formaldehyde. Carpets
were tacked rather than glued, and
beeswax was substituted for polyure-
thane on office floors.
The NRDC renovation, designed by
Kirsten Childs and Randy Croxton of
Croxton Collaborative, achieved a high
level of energy efficiency. Heating
controls are individualized, and sensors
measure outside temperatures to make
use of cool ambient air instead of air
conditioning whenever possible.
Windows contain a heat barrier that
assists in year-round climate control
while allowing large amounts of light to
enter.
Both William McDonough Architects
and Croxton Collaborative are in New
York City.
EPA Document Classifies
Indoor Air Pollution Sources
Research by both EPA and the Consumer
Product Safety Commission indicates that
many building materials and products
commonly found in homes and offices
may be sources of harmful air pollutants.
EPA's Air and Energy Engineering Re-
search laboratory has undertaken an
identification project focusingon materials
found in homes or of fices that are emission
sources, indoor combustion sources, out-
door sources, biological sources, and ac-
tivities which result in pollution of indoor
air. The first product is a classification
system; chemical data will be added in a
report later this fall.

Biologic s Construction Ideas
Environmentally sympathetic
construction ideas are among the many
innovations catalogued in David
Wann's new book Biologic (Johnson
Books, Boulder, Colorado, 1990). Mr.
Wann is a policy analyst in EPA's
Region 8 office in Denver. Ideas
reported in the book include the
following:
•	Ventilation systems built under
basement floors to prevent radon
from seeping into living areas;
•	Housing structures built of aluminum
cans and used tires, then plastered
over to resemble adobe; and
•	Low-toxicity materials, such as silver
plumbing solder and magnesium
oxide wallboard. Paul Bierman-Lytle,
a Connecticut architect who special-
izes in use of such materials, says:
"They have a long life, they are
ecologically sound, they don't
deplete fossil fuel resources, and they
tend to not pollute the environment
during their manufacture."
Biologic also describes some of the
Solar Energy Research Institute's ideas
for energy-efficient control of indoor
environments, including humidity-
storage devices, dessicant wheels that
filter pollutants from the air, and
window glazings of various kinds.

Architects' Environmental Resource Guide will be
Published as a Subscription Service
The American Institute of Architects
(AIA) has announced plans to publish
its Environmental Resource Guide
(ERG) as a subscription service. Each
issue will provide subscribers with
factual information on significant
environmental impacts of building
materials and construction practices.
EPA is supporting preparation of the
ERG through a $700,000 three-year
grant, funded by the Office of Research
and Development and the Pollution
Prevention Office.
The ERG will be organized as a desk
reference for use by architects, engi-
neers, and other design professionals.
Contents will include:
•	Brief summaries on specific construc-
tion materials, such as aluminum,
indicating their impact on natural
resources and health as well as the
amounts of energy consumed and
waste generated during manufactur-
ing or processing;
•	Life cycle considerations; and
•	Annotated bibliographies.
Full-scale research reports will be
available upon request.
"There is a an information vacuum"
among the AIA's 56,000 members, said
Douglas McCreary Greenwood, ERG
Project Director at AIA. "People are
eager to be environmentally responsible
but lack adequate information to make
decisions in this area," he said.
Besides reporting on construction
materials, the ERG will summarize
current scientific research on topics
such as siting, waste, air quality, and
energy. Additional features may
include regulatory updates and news
about environmentally sympathetic
products.
Much of the information will be
drawn from existing sources. The ERG
will meet the need for a presentation
format that is useful to the design or
construction professional.

about environmental impact is either too

anecdotal ('If it stinks, it stinks!') as to be
virtually useless to many architects, or, for
that matter, their clients," stated an AIA
introduction to the Guide.
The ERG is expected to take several
years to publish in its entirety and will
continue to be updated as new scientific
information becomes available. Even-
tually, the ERG will contain information
about materials in all 16 Construction
Specification Institute (CSI) categories
(e.g., site work, concrete, masonry)
including available alternatives.
ERG publication plans call for both a
loose-leaf subscription service and a
computer diskette with search and
retrieval capabilities.
A distinctive feature of the ERG will
be the presentation of positions held by
government agencies, environmental
groups, and private industry on the
environmental impacts of materials,
even when the positions conflict.
To assure accuracy, AIA has enlisted
assistance from science advisors and
technical experts. The AIA stresses that
the ERG will not be "a consensus
document," but will be a key step
towards "a new ethos for the built
environment."

In the States
Firms That Minimize Waste Get Priority
Assistance under New California Program
David C. Hartley and Daniel Q. Garza
Toxic Substances Control Program
California Department
of Health Services
The State of California's Toxic Sub-
stances Control Program (TSCP) has
implemented a program to strip away
some of the regulatory barriers to effective
waste minimization.
The State in early 1990 began integrat-
ing waste minimization into all aspects of
its hazardous waste regulatory program,
thereby producing a net decrease in the
total volume of hazardous waste shipped
off-site for disposal or incineration.
The State's Capacity Assurance Plan,
required under the Comprehensive
Environmental Response, Compensation
and Liability Act (CERCLA), provided a
motive for focused waste minimization.
The plan allows EPA to determine the
status of a state's hazardous waste
management capacity relative to its
hazardous waste generation.
California's plan identified a shortage
of capacity for incinerable liquids, solids,
and sludges. At present, California has no
commercial incineration capacity.
Therefore, a project was begun to reduce
or minimize the amount of incinerable
wastes requiring off-site treatment or
disposal, by integrating waste minimiza-
tion into all TSCP activities, and also
allowing California to comply with its
Capacity Assurance Plan.
The project's goal is the reduction of
incinerable wastes by 50 percent between
1987 and 1992.
A search of the manifest tracking
system was performed to identify the
largest generators of incinerable wastes.
The project focused on facilities genera-
ting greater than 200 tons per year of the
targeted incinerable wastes. This resulted
in a list of approximately 60 facilities,
which comprise the core of the project.
In exchange for signing a nonbinding
agreement to participate, facilities were
promised a high priority for regulatory,
technical, and permit assistance. TSCP
has provided a contact person for each
signatory of the agreement. This contact
person is responsible for working with the
facility and providing it with any assis-
tance within their expertise.
If the facility requests assistance
beyond the contact person's expertise, the
facility is referred to the TSCP's Alterna-
tive Technology Division, which is
comprised of scientists and engineers
capable of researching and developing
solutions to complex problems. The
assistance provided by TSCP will prima-
rily be for issues involving incinerable
wastes and only secondarily for other
waste streams.
Regulatory assistance could involve
helping facilities to untangle the regula-
tory webs that often prevent businesses
from pursuing waste minimization.
Example: A company had a recycling
idea which had not been pursued due to
complex recycling regulations. TSCP
determined that the idea could be
implemented without a permit, and the
company is now able to dramatically
minimize its off-site shipment of hazard-
ous waste.
TSCP also will assist facilities in working
with other regulatory agencies, if necessary,
to bring about waste minimization.
Example: TSCP will intercede on behalf
of a volunteering facility in dealing with
another regulatory agency, e.g., by
meeting with a local air management
district to try to develop an environmen-
tally sound solution to a hazardous waste
problem which crosses media, in this case,
air and land.
TSCP also will give top priority to
permit requests of facilities which have
signed agreements. Currently, a facility
desiring to modify its permit to allow
implementation of waste minimization
might have to wait approximately three to
five years to have its permit reviewed.
Facilities participating in the project have
been promised that their permit applica-
tions will be reviewed in a more timely
fashion.
TSCP's aggressive attempt to integrate
waste minimization into its everyday
activities will be evaluated in 1992, when
the manifest data submitted by the
participating facilities will be compared
with the 1987 data to determine if a net
reduction has occurred. If the project
proves successful, a new waste stream
will be selected and the project repeated!
California/EPA WRITE Program. . .
The California/EPA Waste Reduction
Innovative Technology Evaluation
(WRITE) Program is now in its second
year of technically and economically
evaluating waste reduction technolo-
gies. The EPA WRITE Program is a
national research demonstration
program designed to evaluate the use of
innovative engineering and scientific
technologies to reduce the amount and/
or toxicity of wastes generated from the
manufacture, processing, and use of
hazardous materials.
One recently completed WRITE
Project evaluated an Advanced Reverse
Osmosis System (AROS) to treat and
recover Watts nickel sulfate plating bath
solution and rinse water at the Hewlett
Packard (HP) Facility in Sunnyvale,
California. The 5-gpm unit, a ZDR-500,
has specially adapted membranes that
do not require pH adjustment to
neutral, a microprocessor to manage
specially adapted reverse osmosis (RO)
membranes, and a continuous monitor-
ing system that monitors the influent,
permeate, and concentrate for tempera-
ture, flow rate, and conductivity.
Procedure
The AROS unit was installed,
debugged, and tested in December, 1989
and was operational 210 days in 1990.
The plating operation tested with the
AROS unit was a Watts nickel plating
line consisting of two plating baths

ment issues will be raised in a way
that the museum hopes will assist
visitors in making personal and
political decisions.
"Our Urban Environment" will
include presentations on the environ-
mentally conscious home; wastewater
treatment, water quality, water supply
and the water cycle; recycling, source
reduction and solid waste disposal-
industrial use of chemicals, hazardous
waste disposal, toxics monitoring and
methods of risk assessment; air
quality, mobile and stationary sources
of air pollution and the atmospheric
cycle; community concerns and urban
planning; and the connection between
local and global concerns.
The first module of the exhibit 'Our
Urban Environment' was installed last
year. The trash can represents the 4,238
pounds of trash generated per person in
Los Angeles County each year, includ-
ing both residential and commercial/
industrial garbage. The trash can has
wedges that visitors can pull out to see
potentially recyclable trash represented.
By turning a crank, they can see the
portion of the waste stream that cannot
currently be recycled.
Projected opening date for the
entire exhibit is late 1991. The exhibit
will be in place for at least five years.
'Urban Environment' Exhibit To Open in L.A.
The California Museum of Science
and Industry in Los Angeles is
planning to open an exhibit this year
entitled "Our Urban Environment"
aimed especially at young people.
The objective is to stimulate interest
and educate visitors about environ-
mental issues that affect daily life.
Focusing on Los Angeles Basin
environmental issues, the exhibit will
show the scientific aspects of air
quality, solid and liquid waste
management, and urban growth.

"clean" rinse tank. The rinse water flows
countercurrent to the flow of the items
being plated. The overflow from the
"dirty" rinse tank, 4 to 5 gpm, is the
wastewater that becomes the influent to
the AROS unit.
Four streams were sampled in
October, 1990, according to an EPA
approved Quality Assurance Project
Plan. The waste streams included: (1)
influent to the AROS treatment unit
("dirty" nickel plating rinse), (2)
deionized water used as makeup water
to the AROS unit, (3) permeate, consist-
ing of deionized water produced by the
AROS unit and returned to the "clean"
rinse tank, and (4) nickel plating
solution concentrate produced by the
unit and returned to plating bath #1.
Sample analysis included nickel,
chloride, sulfates, pH, total dissolved
solids, conductivity, color, and total
organic carbon.
Results and Conclusions
Hewlett Packard determined that the
concentrate consisting of 50 percent
nickel plating solution produced by the
AROS unit could be returned to plating
bath #1. The permeate (deionized water)
from the AROS unit was also acceptable
for reuse in the "clean" rinse tank.
An economic assessment was
performed by comparing the costs of
operating the wastewater treatment
system and deionized water production
operations with owning and operating
the AROS unit. The major incremental
cost savings resulting from the use of
the AROS unit was estimated at $26,250
per year. The annual expenditure for
owning and operating the AROS unit
system was $9,419. The net annual
savings was $16,831. The AROS unit
costs $75,000, which represents $63,000
for the unit and $12,000 for making the
installation permanent and training of
operating personnel. The payback
period is 4.4 years.
The final report containing the
economic and technical evaluation will
be available in July, 1991. For more

the Risk Reduction Engineering Labora-
tory at (513) 569-7643 or Robert Ludwig
