Reported chemical releases (TRI)
Facility self-report to EPA's Toxics Release Inventory. Pounds are not concentrations at any address, and chemicals differ widely in toxicity; do not add them together.
2024 air releases: 239 lb, compared with 996 lb in 2023. Water: 0 lb. Carcinogen-flagged air releases: 8 lb.
| Chemical | Year | Fugitive air | Stack air | Water | Unit | OSHA carcinogen |
|---|---|---|---|---|---|---|
| Copper | 2024 | 174 | 0 | 0 | Pounds | No |
| Silver compounds | 2024 | 52 | 4 | 0 | Pounds | No |
| Cadmium compounds | 2024 | 6 | 2 | 0 | Pounds | Yes |
| Nitrate compounds (water dissociable; reportable only when in aqueous solution) | 2024 | 0 | 0 | 0 | Pounds | No |
| Ammonia | 2024 | 0 | 0 | 0 | Pounds | No |
| Nitrate compounds (water dissociable; reportable only when in aqueous solution) | 2023 | 125 | 662 | 0 | Pounds | No |

EPA air-program record
Linked by EPA TRI facility ID. A violation can be procedural (monitoring, reporting, permit conditions) or an emissions exceedance; the detailed facility report says which.
- Quarters with a violation in the last three years: 0
- Last violation: none recorded
- Last evaluation: 2026-01-06
- Last stack test: none recorded
- Enforcement: 0 formal, 0 informal actions · last formal 2011-06-16
Why this may matter, and what to check
A source is not an exposure measurement. Health effects depend on the chemical or physical agent, whether it reaches a person, its concentration, exposure route, duration and individual susceptibility.
Why this may matter
The chemical, release route and concentration matter more than a facility count or a total number of pounds. Air releases may contribute to exposure downwind; water releases need a water-pathway assessment. Reporting does not itself establish a violation.
How it could reach a home
Air, water and land releases have different transport pathways. Emission mass is not the concentration at an address. Do not add quantities with different units or treat all chemicals as equally toxic.
What remains unknown
- Pollutant concentrations at the address
- Facility-specific exposure contribution
- Whether a compliance issue involved emissions, monitoring or paperwork
What to check next
- Environmental regulator — Review chemical-specific emissions, inspections and the underlying documents for any violation.
- Facility operator — Ask which emissions controls and monitoring apply to the relevant process.
- Environmental professional — Look for a published dispersion or exposure assessment before interpreting personal risk.
