Where this facility sits in the TRI record
Among the 3,917 Chemicals facilities in this database, Si Group Inc reports the 1,213th-largest volume (58.8K lbs). This one site accounts for 27.3% of every pound reported in Baldwin. Its reported volume is concentrated rather than spread: Dinitrobutyl phenol alone is 65.6% 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.
Si Group Inc 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 58.8K lbs in cumulative toxic releases across 3 distinct chemicals, 1 of which (33%) carry a carcinogenic classification. Largest chemicals by pounds: Dinitrobutyl phenol; Nitric acid; Ethylbenzene.
The dominant release pathway is off-site transfers at 33.4K lbs (56.9% of total volume), followed by air releases at 43.1%. Between 2019 and 2023, reported totals increased by 70% - from 7.2K lbs to 12.3K lbs.

Similar-scale peers outside Alabama: Greenamerica Biofuels Ord LLC; Albaugh Inc.; Innophos LLC; Ascent Chemicals.
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 Si Group Inc has filed with the EPA under federal community right-to-know requirements - open Stella-Jones Corp for a different chemical mix before treating volume as risk.

About TRI Data
Data as of 2023 reporting year. Source: U.S. Environmental Protection Agency (EPA) Toxic Release Inventory.
Data comes from the EPA Toxic Release Inventory (TRI) program. Facilities that manufacture, process, or otherwise use listed toxic chemicals above threshold amounts are required to report annually to the EPA.
On this page the largest disclosed chemicals include Dinitrobutyl phenol, Nitric acid, Ethylbenzene; nearby reporters include Stella-Jones Corp. "Total releases" includes air, water, land, and off-site transfers for disposal, aggregated across available reporting years. Quantities are self-reported estimates, not measured stack emissions.
PlainEnviro presents this data without advocacy framing. The presence of a facility in the TRI database does not by itself indicate a health risk. For site-specific health questions, consult your local environmental or health agency.
