Where this facility sits in the TRI record
Among the 1,603 Transportation Equipment facilities in this database, Gkn Aerospace Chem-Tronics Inc reports the 122nd-largest volume, placing it in the top 7.6% of its sector. Its reported volume is concentrated rather than spread: Nitrate compounds (water dissociable; reportable only when in aqueous solution) alone is 79.3% of the total.
Placement is computed from reported TRI pounds in this database. Thresholds are fixed across every facility page: concentrated ≥60% of volume in one chemical, county-dominant ≥25% of the county total, carcinogen-heavy ≥50% of pounds. Share-based statements are shown only for sites reporting at least 1,000 lbs, because a share of a very small total is not a meaningful signal. Reported pounds are self-reported estimates and do not measure toxicity or health risk.
