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) | ||||||
|---|---|---|---|---|---|---|
| Year | Arsenic compounds | Nitrate compounds (water dissociable; reportable only when in aqueous solution) | Copper compounds | Ammonia | Propylene | Total (lbs) |
| 1998 | 5,100,080 | 120,007 | 12,000 | 790 | 410 | 5,233,470 |
▎ 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.
