Firstenergy Corp ranks #50 of 4,988 slug-merged TRI parents by disclosed release pounds, mid-to-upper among parents, not a top-25 volume name. Firstenergy Corp's TRI Form R footprint is concentrated in a single state (West Virginia), so statewide context matters more than a multi-state portfolio read. Releases are facility-concentrated: Harrison Power Station accounts for most of Firstenergy Corp's disclosed pounds, so peer comparisons should weight that site, not an even portfolio average.
Parent aggregation for Firstenergy Corp follows facility-reported names. Compare the named neighbors (American Electric Power; The Chemours Co) before treating rank as a hazard score; TRI stays self-reported and unweighted by toxicity.
