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:

 

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

 

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:

 

Air

 

Water

 

Land

 

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:

 

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.

 

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:

 

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:

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.

 

Chemicals in Waste

 

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):

 

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.

 

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:
