Illumina is an EPA Toxics Release Inventory reporter in San Diego, CA, in the computers and electronic products sector. It reported 764 lbs of releases across 2 chemicals in 2023, and 13.9K lbs in total across its 2019-2023 reporting years. That ranks 9,072 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: Miramar Plant 33; Integrated Dna Technologies; Sherwin-Williams Co; Integrated Dna Technologies. Similar-scale Computers and Electronic Products peers outside California: Diodes US Manufacturing Inc; Supelco; Innovaflex; Vj Technologies Inc.. Largest disclosed chemicals by pounds: Acetonitrile; Dichloromethane.
Illumina has reported 13.9K lbs of toxic releases across 2 chemicals to the EPA Toxic Release Inventory, based on annual facility disclosures from 2019 through 2023. Of the chemicals reported, 1 is classified as carcinogen, representing 50% of the facility's chemical profile. The facility operates in the Computers and Electronic Products sector. The primary release pathway is air releases, accounting for 100% 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 760 Computers and Electronic Products facilities in this database, Illumina reports the 140th-largest volume, placing it in the top 18.4% of its sector. Its reported volume is concentrated rather than spread: Acetonitrile alone is 65.7% 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.
Illumina files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 334516 (Computers and Electronic Products). Across 5 years of records spanning 2019–2023, the site has disclosed 13.9K lbs in cumulative toxic releases across 2 distinct chemicals, 1 of which (50%) carry a carcinogenic classification. Largest chemicals by pounds: Acetonitrile; Dichloromethane.
The dominant release pathway is air releases at 13.9K lbs (100.0% of total volume). Between 2019 and 2023, reported totals decreased by 71% - from 2.7K lbs to 764 lbs. Nearest other TRI reporters: Miramar Plant 33; Integrated Dna Technologies; Sherwin-Williams Co; Integrated Dna Technologies. Similar-scale peers outside California: Diodes US Manufacturing Inc; Supelco; Innovaflex; Vj Technologies Inc..
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 Illumina has filed with the EPA under federal community right-to-know requirements - open Miramar Plant 33 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 Acetonitrile, Dichloromethane; nearby reporters include Miramar Plant 33. "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.
