Where this facility sits in the TRI record
Among the 760 Computers and Electronic Products facilities in this database, Southbay Circuits Inc reports the 326th-largest volume (166 lbs).
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.
Southbay Circuits Inc files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 334412 (Computers and Electronic Products). Across 5 years of records spanning 2019–2023, the site has disclosed 166 lbs in cumulative toxic releases across 4 distinct chemicals. Largest chemicals by pounds: Copper And Copper Compounds; Copper compounds; Lead And Lead Compounds; Lead compounds.
The dominant release pathway is off-site transfers at 166 lbs (100.0% of total volume). Between 2019 and 2023, reported totals decreased by 57% - from 37 lbs to 16 lbs. Nearest other TRI reporters: Advanced Circuits Inc; Brenntag Pacific Inc Chandler; Honeywell Electronic Chemicals LLC; Rogers Corp - Roosevelt. Similar-scale peers outside Arizona: Undersea Systems; Creation Tchnologies Wheeling; Teledyne Aes; Amphenol Thermometrics 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 Southbay Circuits Inc has filed with the EPA under federal community right-to-know requirements - open Advanced Circuits Inc 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 Copper And Copper Compounds, Copper compounds, Lead And Lead Compounds, Lead compounds; nearby reporters include Advanced Circuits Inc. "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.
