High-Purity Silicon America Corp is an EPA Toxics Release Inventory reporter in Theodore, AL, in the primary metals sector. It reported 44.9K lbs of releases across 5 chemicals in 2023, and 174.7K lbs in total across its 2019-2023 reporting years. That ranks 3,481 of 25,986 TRI facilities nationwide by cumulative reported pounds, counting each facility over however many years it has filed. Reported volume rose against 2022. Pounds reported are not a measure of toxicity or health risk. Nearest other TRI reporters: Basf Trilon M; Skw Quab Chemicals; Basf Acm; Ineos Phenol. Similar-scale Primary Metals peers outside Alabama: Le Sueur Inc; Ball Advanced Aluminum Technologies Corp; Luvata Appleton LLC; Mueller Co. Largest disclosed chemicals by pounds: Nitrate compounds (water dissociable; reportable only when in aqueous solution); Hydrochloric acid (acid aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size); Nitric acid; Ammonia.
High-Purity Silicon America Corp has reported 174.7K lbs of toxic releases across 5 chemicals to the EPA Toxic Release Inventory, based on annual facility disclosures from 2019 through 2023. The facility operates in the Primary Metals sector. The primary release pathway is off-site transfers, accounting for 85% of total releases. All release data shown below is self-reported to the EPA under the Emergency Planning and Community Right-to-Know Act (EPCRA) Section 313.
Where this facility sits in the TRI record
Among the 1,603 Primary Metals facilities in this database, High-Purity Silicon America Corp reports the 326th-largest volume, placing it in the top 20.3% of its sector. Its reported volume is concentrated rather than spread: Nitrate compounds (water dissociable; reportable only when in aqueous solution) alone is 85.3% 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.
High-Purity Silicon America Corp files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 331410 (Primary Metals). Across 5 years of records spanning 2019–2023, the site has disclosed 174.7K lbs in cumulative toxic releases across 5 distinct chemicals. Largest chemicals by pounds: Nitrate compounds (water dissociable; reportable only when in aqueous solution); Hydrochloric acid (acid aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size); Nitric acid; Ammonia.
The dominant release pathway is off-site transfers at 149.0K lbs (85.3% of total volume), followed by air releases at 14.7%. Between 2019 and 2023, reported totals increased by 57% - from 28.6K lbs to 44.9K lbs. Nearest other TRI reporters: Basf Trilon M; Skw Quab Chemicals; Basf Acm; Ineos Phenol. Similar-scale peers outside Alabama: Le Sueur Inc; Ball Advanced Aluminum Technologies Corp; Luvata Appleton LLC; Mueller Co.
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 High-Purity Silicon America Corp has filed with the EPA under federal community right-to-know requirements - open Basf Trilon M 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 Nitrate compounds (water dissociable; reportable only when in aqueous solution), Hydrochloric acid (acid aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size), Nitric acid, Ammonia; nearby reporters include Basf Trilon M. "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.
