2003 Dioxin Data from Major Chlorine Producers and Users

Under Section 313 of the Emergency Planning and Community-Right-to-know Act, facilities that manufacture, process, or otherwise use certain toxic materials are required to report amounts of emissions of these materials to air, water and land if they exceed established activity thresholds. Reported amounts are compiled in the Toxics Release Inventory (TRI). The TRI also requires facilities to report their pollution-prevention and recycling data. The Environmental Protection Agency (EPA) compiles TRI data each year, publishes an annual report, and makes the data available to the public via the Internet.

PCDD/Fs are a category of compounds that were added to the TRI in 2000. Industries are now required to report PCDD/F emissions, pollution-prevention, and recycling data.

This webpage presents PCDD/F data submitted by major industrial producers and users of chlorine. Data on this webpage are representative of PCDD/F releases for greater than 90% of chlorine and nearly 100% of vinyl chloride US production and over 75% of other chemical uses of chlorine. It provides data on PCDD/F releases, treatment, disposal and transfer activities. PCDD/F data, in numerical form, are reported in the links below using two types of units: (1) TEQ, denoting "Toxic Equivalent," a quantitative measure of the combined toxicity of a mixture of dioxin-like chemicals, and (2) TM-17, denoting "Total Mass of 17 different types of dioxin family compounds of concern."
