U.S. Tva Bull Run Fossil Plant – Emissions Trend

Clinton, TN · 2019–2023 · Parent: US Tennessee Valley Authority

This page assembles 5 consecutive years of EPA Toxics Release Inventory Form R filings for U.S. Tva Bull Run Fossil Plant, 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 291.1K in 2019 and closed at 152.3K in 2023 – a decrease of 47.7% 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 Sulfuric acid (acid aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size) at 292.0K, followed by Barium compounds (except for barium sulfate (CAS No. 7727-43-7)) at 133.4K.

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 electric utilities facility.

About This Data

Trend data is sourced from the EPA Toxic Release Inventory (TRI). Facilities report annually. Release quantities are self-reported estimates. Year-over-year changes may reflect changes in production, pollution control measures, reporting methodology, or chemical thresholds.

A decrease in reported releases does not necessarily indicate improved environmental performance, as it may reflect production cutbacks, facility closures, or changes in reporting requirements. Similarly, increases may reflect expanded production rather than degraded environmental practices.
