Corex ranks #191 of 4,988 slug-merged TRI parents by disclosed release pounds, mid-to-upper among parents, not a top-25 volume name. Corex files across 2 states, a regional parent portfolio rather than a single-state discloser. Releases are facility-concentrated: American Chrome & Chemicals accounts for most of Corex's disclosed pounds, so peer comparisons should weight that site, not an even portfolio average.
Parent aggregation for Corex follows facility-reported names. Compare the named neighbors (Befesa Zinc US Inc.; Duke Energy Corp; US Department of Defense) before treating rank as a hazard score; TRI stays self-reported and unweighted by toxicity.
