U.S. Toxic Release and Canadian National Pollutant Release Inventories

Every year, we report the release of certain chemicals into the air, water and land under the U.S. Toxic Release Inventory and the Canadian National Pollutant Release Inventory. With rare exceptions, these are lawfully permitted releases that are made in a controlled fashion after steps have been taken to reduce the emissions and mitigate their effects.

Both inventories mandate that we report total emissions without regard to changes in production levels.

  1. 2010 is the most recent reporting period.
  2. Dashes indicate a chemical was not required to be reported for these years or there was no quantity to report.
  3. Dioxin is presented in grams, while other chemicals are presented in tons. All required dioxin isomers and compounds are reported regardless of their relative toxicity.
  4. Amount shown includes disposal of materials as part of approved remediation activities as well as from normal operational discharges. The dioxin in materials disposed as part of remediation activities was created by discontinued processes.
