Environmental Toxic Release Inventory

Chlor—alkah production is the largest iadustrial source of mercury release ia the United States (see Alkali and chlorine products). For the 1991 reporting year, chlor—alkah faciUties accounted for almost 20% of the faciUties that reported releases of mercury to the U.S. Environmental Protection Agency (EPA) for inclusion onto the Toxics Release Inventory (TRI) (25).

According to the Toxics Release Inventory, in 1994, the estimated releases of lead of 1,728,918 pounds (784,224 kg) to air from 1,454 large processing facilities accounted for about 10.2% of the total environmental releases of lead (TRI96 1998). Table 5-1 lists amounts released from these facilities. The TRI data should be used with caution, however, since only certain types of facilities are required to report. This is not an exhaustive list.

Commenting ona January 5,1999 proposal, environmental groups in early April called again on EPA to lower its proposed Toxic Release Inventory (TRI) reporting threshold to zero for certain chemicals. The chemicals include mercury, dioxins, and lead. Currently facilities are only required to report chemical releases if they manufacture or process at least 25,000 pounds or otherwise use 10,000 pounds annually of a fisted TRI chemical. The environmental advocates argued that any releases of chemicals considered to be persistent, bioaccumulative and toxic should be reported as a threat to public health. This abstract includes all the information contained in the original article. 

Uranium production does have a notable impact on ozone depletion. The Environmental Protection Agency s (EPA) Toxic Release Inventory showed that in 1999, the nation s two commercial nuclear fuel-manufacturing plants released 88% of the ozone-depleting chemical CFC-11 by industrial sources in the U.S. and 14% of the discharges in the whole world.

The purpose of this chapter is to summarize and generalize the various pollution, health, and environmental problems especially specific to the chemical industry and to place in perspective government laws and regulations as well as industry efforts to control these problems. A brief survey of air and water pollution problems will be given, but these are characteristic of all industry and the topics are too vast to be covered adequately in this book. We will be more concerned with toxic chemical pollution and its control and will spend some time on the Toxic Substances Control Act (TSCA, TOSCA) of 1976 and the Toxic Release Inventory (TRI) list begun in 1988.

A searchable model that links air emissions from an individual plant to the toxicity of each chemical emitted as well as exposure to residents living near the plant was released by the Environmental Protection Agency. The Risk-Screening Environmental Indicators model is based on EPA s Toxics Release Inventory (TRl), which lists some 600 chemicals, the emissions of which have been reported annually by 38,000 facilities in the past 10 years. However, the new model adds data on chemical toxicity and human exposure to produce an indicator of relative risk. 

Hazardous air pollutants such as hexane and methanol are regulated under the Clean Air Act (CAA) (U.S. EPA, 1990a). Volatile organics, defined by the U.S. Environmental Protection Agency G-I S. EPA) as compounds that evaporate at the temperature of use and react with oxygen to form tropospheric ozone, are also restricted under the CAA. Further, the Toxic Release Inventory Bill requires solvent users to record their releases and waste carefully. A summary of many of the federal, state, and local regulations is found in a review by Breen and Dellarco (Breen and Dellarco, 1992). 

Surface water discharges of di(2-ethylhexyl) phthalate from 298 industrial facilities in 1994 in the United States amounted to 264 kg, as reported in the Environmental Protection Agency Toxics Release Inventory (Environmental Protection Agency, 1999d). 

According to the Environmental Protection Agency (1999d) Toxics Release Inventory (TRI) in 1997, air emissions of ethylbenzene from 1005 industrial facilities were approximately 4 000 000 kg in the United States, which accounted for about 92% of the total environmental releases of ethylbenzene. 

According to the Toxics Release Inventory (Environmental Protection Agency, 1997), air emissions of ori/zo-toluidine from 23 industrial facilities were approximately 5260 kg in 1995 in the United States.
