The list currently includes 575 individual chemicals and 28 chemical categories. A chemical category may include a discreet list of chemicals or may represent any chemical that possesses the category's characteristics. The total annual amount of the chemical manufactured, processed, or otherwise used does not exceed 1,000,000 pounds. An important consideration to keep in mind about this data is that TRI does not provide an indication of potential exposure to the reported releases and cannot be used by itself to determine the impact on public health. The chemical's release rate, toxicity, and environmental fate, as well as local meteorology and the proximity of nearby communities to the release must be considered when assessing exposures.
All amounts are in pounds per calendar year.
Data is periodically updated as a result of receiving late reports and revisions to previously submitted reports. Analysis of the TRI data from Delaware facilities is performed and published annually in the Delaware Toxics Release Inventory Report. This report contains tables, charts, and maps that present more than a dozen different analyses, including statewide rankings and trends. This report also provides a more detailed description of the TRI program than is presented here. Any questions about the TRI program or requests for additional TRI data should be directed to the TRI Coordinator at the same number.
