Toxics Watch 1995
Toxics Watch 1995 addresses the problems that arise from the use
of major industrial toxic chemicals. These chemicals, primarily synthetic,
have experienced explosive growth beginning in the mid-1940s. Today, they
are made or used in more than 200,000 facilities in the United States alone
- from small operations with a handful of employees to giant multinational
corporations with thousands of workers.
More than 72,000 different chemicals are circulating through the US
economy. Each year, nearly 6 trillion pounds of these chemicals are
produced, and they play a role in plastics, adhesives, semiconductors,
fuels, dyes, and other products. In this country, 24,000 manufacturing
plants that are subject to federal reporting requirements reported that they
had generated more than 37 billion pounds of chemical waste in 1992.
Toxics Watch 1995 inaugurates a series of reports, grounded in
data analysis, that will provide a comprehensive examination of the state of
knowledge regarding environmental toxic chemical problems and solutions. The
goal of these reports is to help US leaders and citizens address toxic
chemical problems more effectively. Toxics Watch 1995 provides:
- an assessment of the most significant sources of toxic contamination
at sites that range from the human body and the Great Lakes to US
hazardous waste sites and the stratospheric ozone layer
- the first listings of the 100 companies that generate the greatest
quantities of production-related toxic chemical wastes, carcinogens, and
ozone-depleting chemicals in the United States
- the first overview of inventory data compiled under the Toxic
Substances Control Act (TSCA) on the production of synthetic organic
chemicals in the United States
- the first breakdown of how individual companies are managing their
wastes, including a breakdown of which companies are moving most rapidly
away from disposal, the least environmentally sound strategy
- an assessment of what is known about US companies' progress towards
preventing pollution
- the first analysis of the quality of US Environmental Protection
Agency databases' coverage of toxic chemical production, use, and movement
through our economy
- three special-feature chapters that examine the environmental justice
movement; the EPA's 33/50 program, which seeks voluntary corporate efforts
to reduce transfers and releases of 17 key chemicals; and state data
collection systems that go beyond federal reporting requirements.
Toxics Watch's Focus on Pollution Prevention: The Surest Way to Avoid
Toxic Contamination
Cleaning up the environment after toxic chemical contamination occurs is,
at best, difficult and costly. At worst, it is an impossible task. There are
not enough dollars in the US economy to resolve all the contamination
problems resulting from industries and products. To clean up or even
stabilize contaminated hazardous waste sites in the United States may cost
as much as 1 trillion dollars. Cleansing the Great Lakes completely of their
many toxic contaminants or clearing the stratosphere of ozone-depleting
substances seems inconceivable at any expense.
Another way of approaching toxic substances in the environment is to
isolate people from contact with the environment - for example, declaring a
waterway off-limits for fishing, swimming, or drinking. This can be done
quickly, costs far less than cleanup, and offers much greater certainty of
success. But isolation strategies can deny people the enjoyment of their
environment. In addition, isolation usually provides no ecological
protection and does not lead to environmental restoration, so problems are
passed on to future generations.
Only one approach to toxic chemical contamination is relatively
inexpensive to implement and saves money, and that is to prevent pollution
in the first place. Pollution prevention, also known as source reduction,
pays industry back in improved industrial efficiency; leads to better
process and product consistency; eliminates the need for costly
environmental remediation; and reduces health and environmental risks with
greater certainty than any other method. This approach also avoids
ecological damage and preserves the environment, intact, for generations to
come.
Business, government, and environmental leaders now agree that preventing
waste at the source is the superior strategy. The unanimously passed federal
Pollution Prevention Act of 1990 declares that "source reduction is
fundamentally different and more desirable than waste management and
pollution control."
According to the Pollution Prevention Act, if pollution is not prevented,
it should be recycled in an environmentally sound manner; in the absence of
feasible prevention and recycling opportunities, pollution should be
incinerated to recover energy or treated. Disposal of waste or its release
into the environment should be used only as a last resort.
Risk assessment and cost-benefit analysis of toxic contamination are
valuable tools for prioritizing programs focused on waste that has already
been created. But such analyses are costly themselves and are often
inconclusive. On the other hand, putting more effort into prevention avoids
both future risks and future costs.
Because of all the benefits that pollution prevention provides, the
analyses in Toxics Watch 1995 focus on the extent to which US
industry is implementing or failing to implement pollution prevention
measures.
Major Findings of Toxics Watch 1995
- Publicly available data provide no clear quantitative picture of US
chemical production, use, or presence in the environment.
- Despite gaps in available data, it is clear that the volume of toxic
chemicals used in commerce in the United States is huge: about 6 trillion
pounds per year, with production increasing.
- Confidential business information claims allowed under federal law are
broad and interfere with the public's ability to properly interpret data
that is publicly available.
- Toxic chemicals dispersed to the environment through the use of
commercial products are a significant source of environmental
contamination, in some settings comprising the predominant source of
contamination.
- Chemicals brought into commerce before 1979, when the US Environmental
Protection Agency (EPA) began its review of new chemicals under the Toxic
Substances Control Act, constitute more than 99.9 percent of current
production. These chemicals are marketed with few restrictions on use and
account for most of the growing volume of chemical production.
- Data from the US Toxics Release Inventory (TRI) show that, despite
significant achievements by individual facilities and some smaller
industries, there is no overall national reduction in toxic waste
generation by the 24,000 plants that report to TRI. Overall, there has
been a net increase in TRI waste generated since 1991. TRI data show that
production-related generation of specific chemical waste increased 3
percent between 1991 and 1992. Data reported to the Resource Conservation
and Recovery Act's Biennial Reporting System (BRS) show that generation of
BRS toxic waste increased 9 percent between 1989 and 1991.
- Neither the TRI nor the BRS waste-tracking systems allow measurement
of the quantity of toxic chemicals in waste reduced by source
reduction.
- The data reported by some companies reputed to have made great strides
toward waste prevention do not show such results.
- Massachusetts and New Jersey, both of which collect data that go
beyond that required for the federal TRI, each collect a set of data that
permit a much clearer picture of toxic chemical use than do the data
collected by TRI. In both states, chemical, industrial, and geographical
distribution is revealed to be very different with respect to use of
chemicals than it is for either waste generation or environmental releases
and transfers.
Toxics in the Environment: A Dearth of National Information
Knowing the ambient concentrations of chemicals in our air, water, soils,
or biological species is vital. Such information enables us to identify
those chemicals most likely to cause health and environmental problems and
to measure ecosystem exposure. This information provides an important,
although imperfect, predictor of human exposure.
After six months of searching chemical concentration databases, Toxics
Watch 1995 found that the available data could not supply basic answers
regarding national or regional concentrations of chemicals in our
environment:
- Because of the databases' limitations, it is not possible to draw,
with confidence, any nationwide conclusions about contamination of the
ambient environment by toxic chemicals.
- Databases on chemical releases, while valuable for understanding waste
released from manufacturing facilities, are of little use for predicting
national or regional concentrations.
- While hundreds or perhaps thousands of databases contain information
on toxic chemicals in the environment, Toxics Watch 1995 identified
fewer than a score that are both national in scope and broad in coverage
of toxic chemicals. Few of those are current and non-duplicative.
- The few databases that are national in scope and that cover a large
set of toxic chemicals contain comparatively few measurements on many of
those chemicals. Toxics Watch found that particular chemicals too
often have been measured at only a tiny fraction of sites and/or on a few
occasions.
- The lack of consistency in public databases' monitoring methods and in
conditions monitored results in uncertainty about any particular portion
of the data; long-term trend analysis is unreliable.
Air
- A huge amount of information is available on the chemical substances
for which National Ambient Air Quality Standards (NAAQS) have been set -
carbon monoxide, lead, nitrogen dioxide, ozone, and sulfur dioxide.
Detailed time-trend data are available on a local, regional, and national
basis. Publications and computer tools make these data readily
accessible.
- There is no such consistent data collection with regard to other toxic
chemicals in air. The data that have been collected do not support any
national conclusions for chemicals other than those that are the subject
of NAAQS.
Water
- EPA's STORET database contains a Water Quality System (WQS) with
information for 800,000 sampling sites on approximately 14,000 water
quality parameters and reports data on approximately 2,500 discrete
chemicals. Most of this information, collected to meet local needs, is of
uneven or unknown quality and consistency; it is not useful for making
reliable assessments of broad regional or national water quality.
- The US Geological Survey's nationwide system of several hundred
stations monitor water quality, with nationally consistent measurement and
reporting, and these data are available in WQS. This very small subset of
WQS data is suitable for evaluating water conditions on a nationwide
basis.
Land
- There is no national database on contaminants in soil comparable to
those for air and water. The most complete, consistent database on soil
contamination comes from investigations of the highly contaminated soil
found at Superfund sites. This database, known as CARD (Contract
Laboratory Program Analytical Results Database), is maintained by EPA's
Office of Solid Waste and Remedial Response and contains information from
hundreds of sites on the majority of the toxic chemicals in the search
set. Because of the nature of site selection and sampling strategy, these
data are not broadly representative of national conditions and cannot be
used to investigate temporal trends.
Toxics in Commerce: Huge Volumes, Scant Information and
Regulation
Few data resources provide a quantitative description of the conditions
and trends of toxic chemicals in commerce. Focusing on chemicals that are
subject to EPA review under the Toxic Substances Control Act (TSCA), Toxics
Watch 1995 finds:
- More than 13 million chemicals have been characterized and reported on
in the scientific literature. An additional 685,000 chemicals are
identified each year. Many chemicals present in nature remain
unidentified.
- There are more than 72,000 chemicals in commerce in the United States,
excluding foods, drugs, cosmetics, and pesticides. Each year, as reported
to EPA, nearly 6 trillion pounds (5,905 billion pounds in 1989) of organic
chemicals are manufactured in or imported to the United States.
- Thousands of chemicals in commerce are of undefined or variable
composition. Their environmental and health hazards are often undefined as
well.
- Almost none of the 72,000 chemicals in commerce in the United States
have been fully characterized for their ability to cause environmental and
health effects.
- No clear picture of US chemical production or use can be obtained. The
paucity of data on the manufacture and use of chemicals makes
quantification impossible. With no database providing the public or the
government with a national overview, it is also not possible to track
product stewardship efforts by companies or facilities.
- Only a portion of the chemical production and use information that can
be found in government databases is available to the public - how much is
uncertain. Industry submits much of its data with claims of
confidentiality, and those data are withheld from the public.
New Chemical Review: Tiny in Scope, Effective Where Used
Preventing toxic substances from entering commerce presents the best
prospect for addressing the environmental and health concerns they raise.
Potential risks are difficult to address once toxic chemicals enter the
market. The more fully integrated a chemical is into the economy, the more
complex are both the regulatory task of removing it from use and the
industrial task of identifying and introducing less harmful substitutes.
Only two categories of chemicals, polychlorinated biphenyls (PCBs) and
chlorofluorocarbons (CFCs), have been targeted for phase-out from commerce
to date.
- Each year, EPA receives proposals for manufacture or import of about
1,500 new chemicals. New chemicals enter commerce through manufacture or
import at the rate of about 500 1,000 per year.
- EPA's program for reviewing new chemicals before they come into
production, begun under TSCA in 1979, is effective in establishing
numerous restrictions to protect health and the environment. Since 1979,
more than half of the chemicals proposed for manufacture have been
withdrawn or have not yet been introduced into commerce. EPA has taken
more than 800 regulatory actions that in some way restrict the use of
chemicals that have been proposed; this compares with just two actions
restricting the manufacture of chemicals already in commerce (PCBs and
CFCs).
- Chemicals brought into commerce before TSCA review began in 1979
constitute more than 99.9 percent of all production, and they are marketed
with few of the type of restrictions on use that apply to new chemicals
reviewed by EPA. Moreover, these pre-existing chemicals account for most
of the growth in chemical production.
Sources of Environmental Toxic Contamination: Products' Role
Underestimated
"End-of-the-pipe" pollution control programs limit releases of certain
chemicals to the environment from identifiable industrial sources and from
other controllable sources, such as automobiles. Such programs reduce
certain kinds of pollution to a degree. But whole other source areas of
environmental chemical pollution have hardly been addressed, including
non-point sources (such as urban and agricultural storm runoff) and
chemicals dispersed to the environment through the use of commercial
products.
Toxic Watch's analysis of sources of environmental contamination
relies on studies of a number of contaminated settings, including the human
body, sites in the Great Lakes region, US Superfund sites, and the
stratospheric ozone layer - sites chosen because they have been the focus of
extensive study. While these studies are helpful in characterizing sources
of toxic chemical pollution, they are by no means comprehensive or
definitive. They point strongly to the following findings:
- Without in any way diminishing the seriousness of the problem of
toxics in industrial waste, the role of product use as a source of
chemical contamination was found to be significant and in some cases
predominant in the settings covered by Toxics Watch 1995. In some cases,
such as lead, indoor air toxics, and ozone depletion, products are the
primary source of the problem; in other environmental settings, such as
the Black River Watershed in Ohio, their role is secondary to industrial
process waste, but still significant.
- Examining some specific environmental settings turns up some
counter-intuitive results about the role of product use, such as:
- For many people, indoor air pollution is a more dangerous source of
toxic contamination than outdoor air pollution.
- The materials in municipal landfills in many cases are at least as
hazardous as those in industrial landfills.
- In the cases of both indoor air and municipal landfills, the
presence of toxic chemicals stems primarily from the intentional use of
toxic chemicals in widely distributed commercial products.
- Even when the environmental setting itself is generally perceived as
industrial - for example, many Superfund sites - much of the contamination
there may arise from the use and disposal of commercial products.
- Toxics Watch's analysis of Superfund sites in three states
found that contamination of 18 of 36 sites was attributable primarily or
in part to commercial product use and disposal, not industrial process
waste. A Texas A & M study of 58 landfills found that of 143 toxic
chemicals found, 60 were found in municipal waste samples, 31 in
industrial waste landfills, and 39 in both.
- The impact of pollution arising from product use is particularly
significant when assessing the total burden in a human body of a
particular toxic chemical or group of chemicals. The cumulative effects of
exposure through product use create hidden hazards that are difficult for
the individual to avoid.
- EPA's estimates of cancer risks from various sources of air pollution
provide approximate information on the relative importance of product use
and industrial process wastes for this category of contamination. The data
show that product use may contribute substantially more to this cancer
risk - between 54 and 90 percent of the total risk from all sources
considered by EPA - than do production wastes, which contributed between 3
and 25 percent.
- Releases of ozone-depleting chemicals to the atmosphere occur during
their manufacture, during the manufacture and processing of products
containing ozone depleters, and throughout the period of product use and
disposal, in some cases for several decades. While the amount of
ozone-depleting chlorofluorocarbons (CFCs) released from use in an
individual product may be small, cumulative effects may be substantial. An
automobile air conditioner releases only about 400 grams of CFCs each
year, but there are 140 million air-conditioned vehicles on the road in
the United States alone. This translates into total annual releases from
US vehicles of 125 million pounds.
- Studies of large geographic settings, including the Great Lakes
region, reveal contamination resulting from all three categories of toxic
chemical sources (industrial process waste, commercial product use, and
natural causes), but knowledge of these sources is very incomplete and
much pollution remains unaccounted for. Less than 1 percent of the lead
that enters Lake Ontario from the Genesee River can be traced to permitted
discharges to that river; the remaining 99 percent comes from sources that
are difficult to measure, including airborne emissions from motor vehicles
and incinerators and urban stormwater runoff.
Toxics in Waste
The Pollution Prevention Act of 1990 (PPA) established a national policy
of preventing pollution or reducing waste at its source. According to the
Act, source reduction "reduces the amount of any hazardous substance,
pollutant, or contaminant entering any waste stream or otherwise released
into the environment...prior to recycling, treatment, or disposal." This
policy is part of the broader concept of an environmental management
hierarchy in which source reduction should be considered first so that waste
is not generated. Once waste exists, waste management options in priority
order include: recycling, incineration with energy recovery, and treatment.
Release - disposal to the environment - is the last and least desirable
option.
The best sources of national information about pollution generation and
prevention are the Toxics Release Inventory (TRI) and the Resource
Conservation and Recovery Act (RCRA) Biennial Reporting System (BRS).
Toxics Watch 1995's analyses of TRI and BRS data show that:
- Generation of toxic waste increased between 1991 and 1992, as reported
to TRI, and between 1989 and 1991, as reported to BRS, the latest
reporting years of data available for this report.
- TRI production-related waste increased by 3 percent between 1991 and
1992, from 36.3 billion pounds to 37.3 billion pounds. More facilities
showed decreases between the two years than increases, but the size of
the average increase exceeded the size of the average decrease.
Facilities have projected a further increase in production-related waste
of 0.3 percent by 1994 from 1992 levels.
- Generation of BRS toxic waste increased 9 percent between 1989 and
1991, from 482.6 billion pounds to 526.3 billion pounds. These figures
represent those toxic waste codes reported in both years. Additional
toxic waste codes were added for 1991 reports, and these new codes
generated an additional 421.9 billion pounds of toxic waste.
- Neither TRI nor BRS allows clear measurement of changes in specific
chemical waste generation that result from source reduction.
- There is no way of analyzing the relationship between quantities of
waste avoided through pollution prevention and production levels, based on
currently available data. What is known is that, despite source reduction
efforts, toxic waste generation continues to rise and every pound of toxic
waste generated adds an increment of risk to the total. There will be no
way to correlate increased waste generation with production levels unless
and until companies provide specific data on the pounds of chemicals they
avoided creating through source reduction initiatives.
Increased production need not result in more production-related waste (in
fact, new production processes may provide the opportunity to make
operations much more efficient and less waste-intensive). Increases in
production-related waste at TRI facilities reporting source reduction
activity were one-fourth as large as increases in production-related waste
at TRI facilities reporting no source reduction.
- Of facilities reporting on toxic waste to BRS, 51 percent reported
undertaking source reduction alone or in conjunction with recycling.
However, these source reduction activities applied to only 7 percent of
the toxic waste streams tracked by BRS and reduced the total amount of
toxic waste generated by just 2 percent. One-third of the total national
reduction reported to BRS was reported by just one reporting facility.
- Of facilities reporting to TRI, 36 percent reported implementing some
source reduction activities. However, the amount of total
production-related waste at these facilities decreased by less than half
of one percent between 1991 and 1992.
- Facilities reporting some level of source reduction activity not only
generated less waste, but also managed the waste they did generate more
responsibly than facilities that did not report any source reduction. TRI
facilities reporting some pollution prevention recycled more of their
waste, released less waste to the environment, and sent less waste to
treatment and disposal facilities than companies that did not report
undertaking any pollution prevention activities. In contrast, facilities
that did not report source reduction efforts showed an increase in the
quantity of waste released to the environment and sent off site for
treatment and disposal.
- TRI facilities report an overall movement toward more desirable waste
management options. Recycling is the most widely used management option
reported to TRI and is projected to increase: 52 percent of
production-related waste was managed by recycling in 1992, and facilities
expect that to rise to 55 percent by 1994.
- Release to the environment and off-site transfer to disposal, the
least environmentally sound waste management options, were still used to
deal with 9 percent of production-related waste in 1992, TRI facilities
reported. These facilities expect that figure to decline to 7 percent by
1994.
- Out of 23,630 facilities reporting to TRI in 1992, the top 50 (those
reporting the largest amounts of production-related waste) represented
only 0.2 percent of the total number but accounted for 43 percent of all
such waste. Hence, both the practices of these facilities and the way in
which they are reporting waste management activities are of paramount
importance in getting a clear picture of TRI production-related waste.
- For 1991, just 50 facilities generated 71 percent of all RCRA toxic
waste reported to BRS.
- Of the five facilities reporting the largest increases and the five
reporting the largest decreases in production-related waste to TRI for
1991-1992, six achieved their losses or gains through reclassifying waste
management activities (especially recalculating on-site recycling as part
of the manufacturing process). Toxics Watch 1995 discovered that two other
facilities made reporting errors that the facilities themselves later
confirmed. These ten facilities reported a 292-million-pound increase and
a 431-million pound decrease in production-related waste.
- Only 25 facilities are responsible for the majority of increases in
TRI waste from 1991 to 1992. While the average TRI increase per facility
was 405,000 pounds, increases at these 25 facilities alone averaged 68.4
million pounds.
- It appears that undertaking of source reduction activities as reported
to TRI was also associated with a decrease in waste generation. While
total production-related waste for all chemicals increased by 3 percent,
waste associated with TRI forms reporting source reduction decreased 0.3
percent, compared with a 4 percent increase in waste associated with forms
that did not report source reduction.
Chemicals in Waste
- Most patterns of waste management and of environmental distribution
for chemical classes are consistent with their common chemical and
physical properties (e.g., nonflammable metals are seldom sent to energy
recovery facilities and volatile ozone depleters are mostly released to
the air). The relative cost of the chemicals is also a factor.
- 81 percent of production-related waste for metals was managed by
recycling in 1992. Metals do not burn and so cannot be used for energy
recovery, and regulations restrict their release and disposal. In
addition, metals are relatively expensive as raw materials when compared
to other chemical classes.
- Recycling accounted for 53 percent of production-related waste
associated with acids/bases/salts in 1992, and treatment for another 41
percent of this waste category. These chemicals are generally inexpensive
and easily recycled or treated, but usually do not burn and have
restrictions on their release and disposal.
- 98 percent of 1992 releases and disposal of halo-organic chemicals
emerged as air emissions, consistent with their uses as solvents and their
relatively high volatility.
- 46 percent of 1992 production-related waste for non-halogenated
organic chemicals was managed by recycling, and an additional 22 percent
was managed by energy recovery - the highest percentage of waste
management by energy recovery among the chemical classes in this report.
This high percentage occurred because most of these chemicals burn
well.
- Among the three groups of chemicals that Toxics Watch 1995 analyzed
separately, carcinogenic chemicals showed an increase in
production-related waste between 1991 and 1992, while ozone-depleting
chemicals and chloro-organic chemicals showed a decrease.
- The decreases reported in production-related waste for
ozone-depleting, halo-organic, and chloro-organic chemicals are consistent
with reported source reduction activities: these three categories showed
greater percentages of forms reporting source reduction activities in 1992
than the other chemical classes and groups. More than 40 percent of the
forms for ozone-depleting, halo-organic, and chloro-organic chemicals
report undertaking source reduction activities in 1992. The average for
all TRI chemicals was 25 percent.
Toxics in Waste by Industry
A number of highly publicized company and industry initiatives have
created programs to limit waste generation as well as to reduce
environmental release and disposal, and these programs go well beyond
compliance with environmental regulations. Companies and industry groups
with such initiatives include Dow Chemical, Du Pont, Monsanto, and the
Chemical Manufacturers Association's (CMA) Responsible Care program.
Responsible Care encourages member companies to establish and maintain
priorities, goals, and plans for waste and release reduction. Responsible
Care also requires that preference be given first to source reduction,
second to recycling and reuse, and third to treatment as a means of
accomplishing these reductions. If successful, such initiatives should, over
time, have an important impact in reducing toxics in waste.
An analysis of the most recent data shows that in the aggregate, no net
reduction occurred in waste generation of TRI chemicals from 1991 to 1992,
nor is any projected in the next two years. Some facilities, companies, and
smaller industries are achieving significant reductions, but their
reductions between 1991 and 1992 are more than offset by the lack of
accomplishments of the others.
On the other hand, aggressive source reduction at major facilities in key
industries could have a significant impact on the aggregate national toxic
waste picture: analysis of the most recent TRI and BRS data shows that a few
industries and facilities dominate toxic waste generation.
The 1992 TRI data and the 1991 BRS data reveal the following on an
industry-by-industry basis (with industry groups defined by their SIC
codes):
- The chemical industry's toxic waste volumes are so large compared with
the other manufacturing industries reporting to TRI that this industry
dominates nearly all TRI statistics on the generation of
production-related waste. The chemical industry generated 19.9 billion
pounds of TRI waste in 1992 - more than half of the 37.3 billion-pound
total. It also generated 69 percent of all carcinogens in TRI waste. The
industry's recycling figures alone account for almost one-third of all TRI
production-related waste. Two chemical plants, First Chemical Corp., in
Pascagoula, Mississippi, and Goodyear Tire & Rubber, in Beaumont,
Texas, reported a third of the industry's and 18 percent of the nation's
total production-related toxic waste because of the methods by which they
calculate on-site recycling. The primary metals industry reported the
second largest amount of production-related waste to TRI (4.0 billion
pounds).
- In the 1991 BRS data, the chemical industry also reported more RCRA
toxic waste generation (388.6 billion pounds) than any other industry. The
petroleum industry reported the second largest amount (270.9 billion
pounds) to BRS.
- Although 23,630 facilities reported on production-related waste to TRI
in 1992, waste generation is concentrated within relatively few facilities
for most industries. The five facilities with the largest amount of
production-related waste within each industry group together contribute 36
percent of the total production-related waste for all industries. A single
R.J. Reynolds facility in Winston-Salem, North Carolina, reported 92
percent of the entire tobacco industry's production-related waste to TRI
in 1992.
- The waste generation reported to BRS was even more concentrated in a
few facilities than the production-related waste reported to TRI. In 1991,
just 17 out of 22,344 facilities reported more than 50 percent of all the
RCRA toxic waste generated.
Geography and Waste
Toxics Watch 1995 examines waste generation and the environmental
management of waste nationally, by state and county, to provide examples of
the types of geography-driven analyses that can be done at this level with
TRI and BRS data. Other types of geographic analyses, which are likely
subjects of future Toxics Watch reports, include: analyses on a watershed or
air-shed basis; co-analyses with demographic data; and analyses of
facilities upwind or upstream of the political jurisdictions their emissions
affect.
Although every state has both TRI and BRS facilities within its borders,
facilities generating the largest amounts of toxic chemicals are
concentrated in only a few states. TRI reports for 1992 and BRS reports for
1991 document clearly that Texas and Louisiana continue to be the states
with the largest amounts of toxic waste.
- Facilities in Texas and Louisiana reported the largest increases in
total TRI production-related waste from 1991 to 1992, while facilities in
Georgia and New Jersey reported the largest decreases.
- Releases and transfers of TRI chemicals remain concentrated in
relatively few of the approximately 3,000 counties in the nation. The 100
counties with the largest amount of releases and transfers accounted for
60 percent of the national total in 1992.
- Generally, rankings and changes in the RCRA waste generation data are
due to single facilities, because the 50 facilities reporting the largest
amounts of toxic waste generated to BRS accounted for 72 percent of all
BRS toxic waste. Sixteen of these facilities are located in Texas.
A Toxics Watch 1995 Feature: Materials Use Accounting and Pollution
Prevention in New Jersey and Massachusetts
Massachusetts and New Jersey collect information from facilities in their
states that goes beyond the data required for the federal Toxics Release
Inventory (TRI). How useful is this additional information in understanding
more fully the risks of a toxic chemical at a facility, how toxic chemicals
are used, the amount of toxic chemicals in commerce, and the amount of
source reduction of toxic chemicals in industrial waste? The Massachusetts
and New Jersey systems differ from one another both in the type of
information collected and because there is a very different mix of
industries in New Jersey as compared with Massachusetts:
- While the data collected by New Jersey and Massachusetts are
different, both permit a much clearer picture of toxic chemical use than
does the data collected for TRI; both require reporting inputs to the
production process in addition to a fuller depiction of outputs. In both
states, chemical, industrial, and geographical distribution is revealed to
be very different with respect to use of chemicals than it is for either
waste generation or environmental releases and transfers.
- New Jersey offers the most complete picture of the flow of a chemical
into a facility, through the facility's processes, and into the facility's
waste and product outputs. This picture provides perspectives completely
lacking from the TRI data for the same facility - including a perspective
on the potential risks posed in the workplace and during the transport of
toxic materials.
- Massachusetts offers the most complete picture of the conditions of
use of the chemical at a facility, obtaining a description of each process
(production unit), the range of amount of chemical use, and the percent
change in waste by process, instead of facility-wide as in New Jersey.
- In contrast to the federal TRI, where only data on the amount of
chemicals in waste and in releases and transfers are reported, both New
Jersey and Massachusetts require data on how much of a toxic chemical is
shipped as or in products from the facilities. For New Jersey, of the
toxic chemical inputs to the manufacturing process (20.0 billion pounds),
34 percent (6.7 billion pounds) ends up as waste, and this is the amount
reported to the TRI. In addition to the TRI data, New Jersey facilities
reported to the state that 2.8 billion pounds (14 percent) were consumed
during the manufacturing process and 10.7 billion pounds (54 percent) were
shipped in products. Massachusetts facilities reported a total of 1
billion pounds of toxic chemicals used, with 14 percent ending up as waste
(by-product) and 42 percent shipped in products. Such data are valuable
because toxic chemicals in products pose as large or larger environmental
threats than industrial wastes, yet much less information is available
about toxics in products.
- Only New Jersey requires the reporting of source reduction quantities,
and the New Jersey data yield the clearest picture of how much source
reduction is actually occurring. The reasons for changes in waste
generation from one year to the next are much clearer in the New Jersey
data than in TRI, because New Jersey requires facilities to report the
specific amount of individual chemicals in waste reduced due to source
reduction activities, the amount of individual change due to
discontinuation of use or relocation of the process to another facility,
and changes in production level.
- Despite much fanfare by government and industry, source reduction of
industrial toxic waste is not occurring to any appreciable extent in New
Jersey. In fact, the trend is in the wrong direction: fewer facilities
reported any source reduction activity in 1992 than in 1991, and the
amount of source reduction they reported was both a smaller amount and a
smaller percentage of waste generation.
