Reported on-site TRI releases in pounds (lbs), grouped by reporting year.
The 10 chemicals with the highest cumulative on-site releases in pounds (lbs) across all available years.
Rows are years. Columns show the five highest-total chemicals across all years plus each year's total release volume.
| All values in pounds (lbs) | ||||||
|---|---|---|---|---|---|---|

▎ Facilities report to EPA's TRI once they manufacture, process, or use a listed chemical above set thresholds. Once that threshold is crossed, they must report actual releases regardless of size — so a small number reflects genuine low-level discharge, not a data error.
