Caterpillar: how the 1.0K lbs splits
1.0K lbs across all reported pathways
- Off-site Transfers 1.0K lbs 100.0%
Caterpillar's 1.0K lbs Form-R total is OFFSITE - off-site transfers is 100.0% of the bar. Off-site transfers stay separate from air, water, and land releases. Leading chemical by pounds: Manganese.
Carcinogen-classified pounds vs other reported pounds
Same cumulative TRI total as above, split by EPA/IARC carcinogen classification on each chemical: pounds share, not chemical count. Classification is not a site health-risk score.
LIGHT volume OFFSITE pathway CARC-LEAN
Caterpillar is an EPA Toxics Release Inventory reporter in South Milwaukee, WI, in the machinery sector. It reported 246 lbs of releases across 3 chemicals in 2023, and 1.0K lbs in total across its 2019-2023 reporting years. That ranks 13,869 of 25,986 TRI facilities nationwide by cumulative reported pounds, counting each facility over however many years it has filed. In Wisconsin's 836 reporting TRI sites, pounds #1 is not chemical-count #1. Caterpillar is pounds #546 and chemical-count #399 at 1.0K lbs. Mullins Cheese Inc leads reported pounds (11.2M lbs) at 3 chemicals (chemical-count #319). Ppg Industries Inc-Oak Creek leads chemical count at 32 chemicals (2.2M lbs, pounds #16). Reported volume fell against 2022. Pounds reported are not a measure of toxicity or health risk.
