Where this facility sits in the TRI record
Among the 3,917 Chemicals facilities in this database, Sterling Specialty Chemicals LLC reports the 283rd-largest volume, placing it in the top 7.2% of its sector. Its reported volume is concentrated rather than spread: Acrylamide alone is 77.1% of the total. Carcinogen-classified chemicals make up 79.0% of the reported pounds, not just of the chemical count.
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.
Sterling Specialty Chemicals LLC files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 325199 (Chemicals). Across 5 years of records spanning 2019–2023, the site has disclosed 882.2K lbs in cumulative toxic releases across 4 distinct chemicals, 2 of which (50%) carry a carcinogenic classification. Largest chemicals by pounds: Acrylamide; Ammonia; Acrylic acid; Acrylonitrile.
The dominant release pathway is off-site transfers at 801.1K lbs (90.8% of total volume), followed by air releases at 9.2%. Between 2019 and 2023, reported totals increased by 1258% - from 27.9K lbs to 379.1K lbs. The facility is operated under parent company Sterling Specialty Chemicals LLC.

Similar-scale peers outside Alabama: Corteva Agriscience LLC - Midland; W R Grace & Co; Ineos Joliet LLC; The Andersons Inc - Sioux City.
TRI Form R values are self-reported estimates, not measured stack emissions, and treat every pound of reported chemical equally regardless of toxicity. Inclusion in the TRI database does not establish a health risk to nearby residents; it documents the annual reporting record that Sterling Specialty Chemicals LLC has filed with the EPA under federal community right-to-know requirements - open Pvs Dx Inc. for a different chemical mix before treating volume as risk.
