A Minnesota plastics company spent four full years quietly importing a chemical that the federal government was simultaneously working to ban outright, and the EPA only found out because of a mandatory reporting window the company simply ignored.

A Company That Builds Things with Chemicals Nobody Was Supposed to Know About

Miller Waste Mills, Inc., doing business as RTP Company, presents itself to the world as a “world leader in specialty thermoplastic compounding,” with manufacturing operations spanning the U.S., Mexico, Europe, and Asia. They make thousands of products per year for electronics, automotive, medical equipment, appliances, and consumer goods. These are the kinds of products that end up in hospitals, in your car, and in your home.

Behind that respectable corporate profile, however, the EPA’s own enforcement documents tell a different story. Between 2016 and 2019, the company imported four distinct chemical substances at its Winona, Minnesota facility for commercial purposes. When the federal reporting window opened in June 2020, requiring every major importer of these chemicals to file disclosure forms, Miller Waste Mills filed nothing.

The reporting deadline was January 29, 2021. The company missed it entirely, for all four chemicals, across multiple years of importation activity. The EPA’s enforcement settlement, finalized in March 2025, describes this as four separate and distinct violations of federal law.

The Numbers They Didn’t Want You to See

The raw import volume numbers sitting in the EPA’s enforcement document are significant. In 2018 alone, the company imported 63,895 pounds of CAS 1333-86-4, a carbon black substance. That same chemical was imported at 30,706 pounds in 2016 and 21,710 pounds in 2017. The EPA’s threshold for mandatory reporting is 25,000 pounds per year; this company blew past that threshold multiple times.

CAS 64742-54-7 showed up at 39,362 pounds in 2019, after appearing at only 748 pounds in 2017 with nothing declared in 2016 or 2018. CAS 1317-65-3 cleared 35,726 pounds in 2019, also unreported. And CAS 1163-19-5, the chemical already targeted for federal regulation, appeared at 5,565 pounds in 2017 alone, exceeding the much lower 2,500-pound reporting threshold that applies specifically to substances under active regulatory action.

Every single one of these chemicals was already listed on the EPA’s master TSCA Inventory, meaning the company knew, or was legally required to know, that it had reporting obligations. This was not an obscure rule buried in fine print.

The Import Data They Buried: Four Chemicals, Four Years

The Non-Financial Ledger: What the Fine Doesn’t Capture

The $112,155 fine (roughly what a median American household earns in two and a half years) is what this case cost Miller Waste Mills on paper. But the ledger that matters, the one measuring actual harm to actual people, runs much deeper than any administrative penalty can reach.

The entire purpose of the EPA’s Chemical Data Reporting system under TSCA is transparency. When companies report which chemicals they are importing and in what volumes, regulators and communities gain the ability to assess cumulative chemical exposure in a region, identify dangerous patterns before they become catastrophes, and update public health guidance in real time. When a company simply does not file, that entire chain of protection goes dark. For the communities near the Winona, Minnesota facility, that chain went dark for four consecutive years.

One of the four chemicals Miller Waste Mills imported, CAS 1163-19-5, carries a specific distinction that makes its omission especially serious. The EPA was already in the process of formally banning this substance under TSCA Section 6 when the company was importing it. The proposed rule came on July 29, 2019. The ban was officially promulgated on February 5, 2021. The company imported 5,565 pounds of it in 2017 and still told no one. The reporting threshold for substances under active regulatory action is much lower, just 2,500 pounds, precisely because the government recognizes that these chemicals demand heightened scrutiny. Miller Waste Mills cleared that threshold and stayed silent anyway.

There is also the dignity dimension. The residents of Winona, Minnesota, a city of roughly 25,000 people on the Mississippi River, live near a facility that was moving tens of thousands of pounds of industrial chemicals annually without any public accountability. These are not abstract numbers. These chemicals pass through supply chains, enter manufacturing processes, and produce byproducts that can enter the air, water, and soil of the surrounding area. The right to know what is being processed in your community is not a bureaucratic nicety. It is the difference between informed community action and enforced ignorance. For four years, Miller Waste Mills chose to keep Winona in the dark.

Legal Receipts: The Document Speaks for Itself

Societal Impact Mapping: Who Actually Pays the Price

Environmental Degradation: The River Town That Wasn’t Warned

The TSCA Chemical Data Reporting system exists specifically to build and maintain a live national picture of chemical substance flows across the country. When Miller Waste Mills imported these substances without filing, that data gap didn’t just disappear into paperwork limbo. It removed real information from the EPA’s master inventory tracking system, the same system regulators use to evaluate cumulative chemical burden in specific regions and to trigger environmental review processes.

Winona, Minnesota sits on the Mississippi River. The Mississippi watershed is already one of the most chemically monitored river systems in North America, precisely because industrial activity along its banks has a long and documented history of contaminating drinking water sources and aquatic ecosystems downstream. Unreported industrial chemical imports at a facility in this geography carry environmental stakes that extend well beyond the facility fence line.

The EPA’s own rules recognize that substances already under regulatory action, like CAS 1163-19-5, warrant a reporting threshold five times lower than ordinary chemicals. That lower threshold exists because regulators have already determined these substances pose a disproportionate risk. The fact that Miller Waste Mills imported that specific substance and still said nothing to regulators means the environmental monitoring infrastructure designed to protect this region simply didn’t work, because the company never plugged it in.

Public Health: Transparency as a Basic Right

The Chemical Data Reporting requirements are the foundation of the public’s right to know what chemicals are circulating in commercial quantities near their homes. Without that data, local health departments cannot issue accurate advisories. Community health researchers cannot identify exposure patterns. Workers inside facilities cannot be properly informed about the cumulative chemical burden of their workplace environment.

CAS 1163-19-5, the substance the EPA was actively seeking to ban at the time of importation, is identified in public regulatory records as a persistent, bioaccumulative substance. The EPA’s decision to pursue a full Section 6 ban, a rarely used and legally demanding enforcement mechanism, signals that federal scientists assessed this substance as presenting an unreasonable risk to human health or the environment. The company imported it anyway, and disclosed it to no one for the entire duration of the reporting cycle.

The Winona community had no information, no ability to respond, and no opportunity to advocate for themselves. That is not a regulatory technicality. That is a community stripped of its basic right to make informed decisions about the environment its members live in.

Economic Inequality: The Fine That Costs Them Nothing

The $112,155 penalty (roughly the equivalent of what a minimum-wage worker in Minnesota would earn across seven full years of full-time work) is the entire financial consequence Miller Waste Mills faces for four years of non-compliance across four chemicals. The EPA’s own settlement language notes that the agency specifically considered the company’s “ability to pay” and its ability “to continue to do business” when setting the fine amount.

That framing tells you everything. A multinational thermoplastic compounding company with manufacturing operations across four continents and a supply chain serving the electronics, automotive, and medical industries negotiated a fine structured not to inconvenience them. The penalty was calibrated to ensure they can keep operating exactly as before. The communities near the Winona facility received no remediation, no enhanced monitoring, and no public notification requirement as part of this settlement.

This is the standard playbook: regulate on paper, enforce with fines companies can absorb, and call it justice. The people who breathe the air and drink the water near that facility don’t get a comparable settlement. They get a press release, if they’re lucky.

The “Cost of a Life” Metric

What Now: Who Answers for This

Who Signed the Settlement

Rolf Dahl, Vice President of Production at Miller Waste Mills, Inc., signed the consent agreement on behalf of the company on February 27, 2025. The EPA’s side was signed by Michael D. Harris, Director, Enforcement and Compliance Assurance Division, EPA Region 5. The company’s contact email on file with the EPA is rdahl@rtpcompany.com.

The Watchlist: Who Should Be Watching

• EPA Region 5 Enforcement and Compliance Assurance Division: responsible for monitoring ongoing TSCA compliance at this facility
• EPA Chemical Data Reporting Program: the system Miller Waste Mills failed to file into for four consecutive years
• EPA Pesticides and Toxics Compliance Section, Region 5: the unit that brought this enforcement action
• Minnesota Pollution Control Agency (MPCA): the state-level agency with independent authority to regulate chemical handling at facilities in Minnesota
• The Toxic Substances Control Act (TSCA) Section 6 Regulatory Process: the federal mechanism used to restrict and ban chemicals like CAS 1163-19-5

The Settlement’s Hidden Escape Hatch

Read the fine print: this settlement “resolves only Respondent’s liability for federal civil penalties for the violations alleged.” It leaves open the possibility of “injunctive or other equitable relief or criminal sanctions” by the EPA or the U.S. government. It also explicitly states that the company’s “responsibility to comply with TSCA and other applicable federal, state and local laws” remains fully intact. In plain English: they paid the ticket, but the road they drove on is still under watch.

What You Can Do Right Now

If you live near a facility that handles industrial chemicals, you have a legal right to know what those chemicals are. The EPA’s Toxic Release Inventory (TRI) database is publicly searchable at epa.gov/toxics-release-inventory-tri-program. Look up your zip code. Look up facilities near you. If you find gaps or inconsistencies, report them to your state’s environmental protection agency and to the EPA’s Region 5 office. Local environmental justice organizations and mutual aid networks can help you file formal information requests, organize community monitoring programs, and pressure state regulators to conduct independent facility inspections. Corporate compliance only improves when communities refuse to stop watching.
