John Deere Waterloo Works Drivetrain Operations and Foundry – Emissions Trend

This page assembles 5 consecutive years of EPA Toxics Release Inventory Form R filings for John Deere Waterloo Works Drivetrain Operations and Foundry, spanning 2019–2023. Each annual total aggregates on-site air emissions, surface-water discharges, land disposal, and off-site transfers reported by the facility under EPCRA Section 313, which requires disclosure whenever a listed chemical is manufactured, processed, or otherwise used above threshold quantities.

Reported releases opened at 120.5K in 2019 and closed at 347.6K in 2023 – a increase of 188.4% over the window. The chart below stacks the four TRI release media (air, water, land, off-site) and overlays the yearly total. The top contributor by cumulative mass is Zinc compounds at 319.8K, followed by Manganese And Manganese Compounds at 216.6K.

Because TRI figures are estimated, not metered, year-over-year deltas can reflect methodology revisions, ownership changes, or shifts in what a facility classifies as reportable, not only physical emission changes. Treat the trajectory as a disclosure record, and cross-reference with the EPA Enforcement and Compliance History Online (ECHO) system for the fuller regulatory picture on this machinery facility.
