Where this facility sits in the TRI record
Among the 3,265 Nonmetallic Mineral Product facilities in this database, Specialty Minerals Inc reports the 433rd-largest volume, placing it in the top 13.3% of its sector.
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.
Specialty Minerals Inc files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 327410 (Nonmetallic Mineral Product). Across 6 years of records spanning 2019–2024, the site has disclosed 5.6K lbs in cumulative toxic releases across 5 distinct chemicals, 2 of which (40%) carry a carcinogenic classification. Largest chemicals by pounds: Lead And Lead Compounds; Lead compounds; Naphthalene; Polycyclic aromatic compounds.
The dominant release pathway is land disposal at 4.8K lbs (70.9% of total volume), followed by off-site transfers at 27.9%. Between 2019 and 2024, reported totals increased by 52% - from 772 lbs to 1.2K lbs.

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 Specialty Minerals Inc has filed with the EPA under federal community right-to-know requirements - open Holland Co 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 Lead And Lead Compounds, Lead compounds, Naphthalene, Polycyclic aromatic compounds; nearby reporters include Holland Co. "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.
