Where this facility sits in the TRI record
Among the 3,917 Chemicals facilities in this database, Afton Chemical Additives Corp reports the 2,466th-largest volume (3.3K lbs). Its reported volume is concentrated rather than spread: Methyl methacrylate alone is 100% 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.
