Where this facility sits in the TRI record
Among the 384 Paper facilities in this database, Westrock Mill Co LLC reports the 30th-largest volume, placing it in the top 7.8% of its sector. This one site accounts for 95.0% of every pound reported in Marengo. Its reported volume is concentrated rather than spread: Methanol alone is 60.9% 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.
Westrock Mill Co LLC files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 322130 (Paper). Across 5 years of records spanning 2019–2023, the site has disclosed 8.0M lbs in cumulative toxic releases across 20 distinct chemicals, 5 of which (25%) carry a carcinogenic classification.

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 Westrock Mill Co LLC has filed with the EPA under federal community right-to-know requirements - open Two Rivers Lumber Co LLC 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 Methanol, Manganese And Manganese Compounds, Ammonia, Nitrate compounds (water dissociable; reportable only when in aqueous solution); nearby reporters include Two Rivers Lumber Co LLC. "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.
