For at least four years, one of the largest zinc and lead mining operations in North America poured corrosive, toxic, and reactive chemical waste down laboratory sinks, through an unlabeled underground tank with no leak detection system, and into a tailings dump in Alaska’s Arctic, and never once told the federal government it was doing any of it.

A Mine at the Top of the World, Playing by Its Own Rules

The Red Dog Mine sits near Kotzebue in northwestern Alaska, one of the most remote and ecologically sensitive regions in the United States. Teck Alaska, Incorporated operates it as a zinc and lead mining complex. According to the EPA’s own consent agreement, the facility includes an Assay Laboratory where chemical testing of ore samples takes place daily, generating a rotating roster of toxic byproducts.

The Assay Laboratory produced at least fifteen distinct categories of chemical waste, including materials from atomic absorption testing, selenium analysis, silica fusion, lead concentrate analysis, zinc titration, and organic carbon determination. The EPA confirmed that fourteen of those waste streams were hazardous at the moment of their creation, exhibiting corrosivity and toxicity characteristics. A fifteenth, called “Used Anhydrone,” was classified as reactive hazardous waste.

Teck Alaska’s response to this daily production of dangerous chemicals was to pour them down two laboratory sinks. Those sinks drained to floor drains. Those floor drains fed into an underground tank buried beneath the laboratory floor. That tank, which the EPA refers to as the “Neutralization Tank,” adjusted the pH of the chemical mixture before pumping it to a sewage lift station, then to a sewage treatment plant, and finally into the mine’s tailings impoundment. That chain of disposal, the EPA found, constituted treatment and land disposal of hazardous waste. All of it. Without a permit. For over four years.

The Clock Starts in October 2019

The EPA pinpoints the start of the documented violations at October 1, 2019. The enforcement action was filed in June 2024, meaning Teck Alaska operated this unpermitted system for at minimum four years and three months before the matter was formally resolved. The consent agreement specifies that the waste disposal into the tailings impoundment continued through at least January 15, 2024.

The most stunning part is what Teck Alaska failed to do with its own paperwork. Federal law requires large quantity generators of hazardous waste to submit biennial reports to the EPA. These reports are the federal government’s primary tool for tracking how much hazardous waste industry generates, where it goes, and whether it is being managed safely. Teck Alaska missed those reports for 2019, 2021, and 2023. Three reporting cycles. Zero filings. The federal government was, for years, flying blind on what this mine was producing and disposing of in the Alaskan Arctic.

The Non-Financial Ledger

What a Number Can’t Capture: The Human and Community Cost

Kotzebue sits on a peninsula in Kotzebue Sound, above the Arctic Circle. The region is home to the Inupiaq people, whose communities have lived in relationship with the land and water here for thousands of years. When a mining company buries a tank full of corrosive and toxic chemicals beneath its laboratory floor, with no secondary containment, no leak detection system, and no daily inspection logs, the people who live nearest to that mine and its tailings cannot know what they don’t know. That is the specific cruelty of corporate environmental negligence: it strips communities of the information they need to protect themselves.

The consent agreement documents that Teck Alaska never labeled the Neutralization Tank or the floor drains with the words “Hazardous Waste.” There was no required warning of the tank’s contents. Workers in that Assay Laboratory poured corrosive acids, toxic lead-containing solutions, and reactive chemicals into sinks above a hidden underground vessel, with no posted indication of what accumulated beneath their feet. Occupational exposure risk is not a hypothetical when you are standing above an unlabeled tank that contains hydrochloric acid digests, lead concentrate residuals, and reactive chemical compounds.

The tailings impoundment is where this chemical chain ended. Tailings impoundments at metal mines are already understood by environmental scientists as high-risk containment structures. They hold the crushed, processed rock left over after extracting valuable metals, and in a zinc and lead mine, those tailings carry heavy metals. Teck Alaska added hazardous laboratory waste to this mix, disposing of it by routing it through a sewage treatment plant and into the impoundment, without a written waste analysis plan, without determining the applicable EPA waste codes, and without verifying compliance with federal treatment standards before land disposal. The community near Kotzebue had no way to know, because the company never reported it.

The settlement allows Teck Alaska to resolve twenty separate violations of federal hazardous waste law by writing a check for $429,794 (roughly what a minimum-wage worker earns over 28 years of full-time labor). The company admits jurisdiction but neither admits nor denies the specific facts. That legal architecture, standard in administrative settlements, means the public gets a fine but no admission of harm. The Inupiaq communities near the Red Dog Mine get a court document that carefully avoids saying the word “sorry” or acknowledging a single consequence to the land, water, or people around it.

Legal Receipts: What the Document Actually Says

Every quote below comes verbatim from the EPA Consent Agreement filed June 7, 2024. Read them slowly.

Societal Impact Mapping

The Red Dog Mine sits in one of the most ecologically intact and climate-sensitive regions on Earth. The Arctic tundra and its water systems are under compounding pressure from climate change and industrial activity. The consent agreement documents that Teck Alaska routed hazardous waste, including materials exhibiting corrosivity and toxicity, through its sewage treatment plant and directly into its tailings impoundment. The tailings impoundment constitutes “land disposal” under federal law, and the EPA confirmed the company performed this disposal without complying with the applicable land disposal restriction treatment standards required before hazardous waste can legally make contact with land.

The EPA’s own definition of impermissible dilution applies directly here: Teck Alaska mixed restricted hazardous waste with water and other solid wastes to change the pH, which federal regulations explicitly prohibit as a substitute for proper treatment. Diluting poison is not the same as neutralizing it. Changing a number on a pH meter does not remove lead, does not remove toxic metals, and does not address the toxicity characteristic that made the waste hazardous in the first place. The company was cutting corners on chemistry while cutting costs on compliance, and the tailings impoundment absorbed the result.

The absence of secondary containment and a leak detection system on the Neutralization Tank is particularly alarming. An underground tank buried beneath a building floor, with no liner, no monitoring, and no detection system, presents an unquantified release risk to whatever sits below and around it. The consent agreement does not include any documented environmental sampling or assessment of whether releases occurred. The public and the surrounding communities receive no answer to the question that matters most: did this tank leak, and if so, for how long, and where did it go?

The waste streams generated in the Red Dog Assay Laboratory are deeply specific and deeply hazardous. Aqua regia, a mixture of nitric and hydrochloric acids used to dissolve metals, produces a digest that is corrosive at the point of generation. Acidified samples from atomic absorption testing, samples from lead concentrate analysis, and residuals from zinc titration all carry the potential for lead contamination. The EPA’s toxicity characteristic covers exactly this scenario: waste that leaches heavy metals at concentrations above regulatory thresholds is classified as toxic hazardous waste.

Workers in the Assay Laboratory poured these materials into sinks above an unlabeled underground tank, with no posted hazard warnings, no indication of corrosivity, and no posted chemical hazard labels compliant with OSHA, DOT, or the National Fire Protection Association. Federal regulations require large quantity generators to label hazardous waste containers and tanks precisely because workers deserve to know what they are working around. Teck Alaska denied those workers that basic protection for over four years.

The region around Kotzebue relies on subsistence hunting and fishing. Water and land are intertwined with food security and cultural identity in ways that have no equivalent in industrial settings. A tailings impoundment that receives impermissibly disposed hazardous waste without proper treatment verification represents a potential pathway for contaminants to enter the broader environment. The consent agreement provides no environmental monitoring data, no health risk assessment, and no community notification requirement. The people closest to the mine receive the least information about what was put into the ground near them.

The maximum penalty under RCRA is $121,275 per day of noncompliance for each violation. Teck Alaska committed at least 20 separate violations, some of which ran for over four years. A simple calculation of the statutory maximum exposure produces a number that would dwarf the company’s actual fine many times over. Instead, Teck Alaska settled for $429,794 (roughly what a minimum-wage worker earns over 28 years of full-time labor). The EPA explicitly noted it weighed statutory factors in arriving at this number. The result is a fine that functions as a cost of doing business, absorbed and moved on from.

The Red Dog Mine is the world’s largest zinc producer. Teck Resources, the Canadian parent company, reported revenues in the billions annually. A $429,794 fine (roughly the price of three luxury condos in a major American city) imposed on a multi-billion-dollar global mining enterprise for four-plus years of illegal hazardous waste management is the economic definition of a slap on the wrist. It incentivizes the calculation that non-compliance is cheaper than compliance, particularly in remote jurisdictions where regulatory oversight is thin and the affected communities have limited political power.

The consent agreement also specifies that the assessed penalty is not tax-deductible. That provision is presented as a punitive safeguard, and it is a real one. But it does not change the fundamental arithmetic: a company that generated hazardous waste illegally for years, never filed three required government reports, and buried an unlabeled tank full of toxic chemicals in the Alaskan Arctic walked away from the entire matter for under half a million dollars. The communities near Kotzebue got no remediation fund, no health screening, no environmental monitoring commitment, and no public acknowledgment of harm.

What Now?

Who Signed. Who Watches. What You Can Do.

Named in the Document:

• Les Yesnik, General Manager, Red Dog Operations, Teck Alaska, Incorporated — signed the consent agreement on behalf of the company.
• Edward J. Kowalski, Director, Enforcement and Compliance Assurance Division, EPA Region 10 — signed for the agency.

Regulatory Bodies with Ongoing Authority:

• U.S. Environmental Protection Agency, Region 10 (Alaska jurisdiction) — responsible for enforcement of RCRA, monitoring corrective actions ordered in the consent agreement, and receiving the overdue biennial reports for 2019, 2021, and 2023 within 90 days of the order’s effective date.
• EPA Office of Inspector General — can investigate whether EPA’s penalty calculation adequately considered the full scope and duration of violations.
• OSHA — has independent authority over workplace hazard communication; the unlabeled tank and sinks represent potential occupational safety violations that this settlement does not address.
• Alaska Department of Environmental Conservation — Alaska has not been delegated authority to administer the federal RCRA hazardous waste program (explicitly stated in the consent agreement), but the state agency retains authority over other environmental statutes applicable to mining operations.

Corrective Actions Ordered (Track These Deadlines):

• Within 60 days: Teck Alaska must re-notify EPA as a large quantity generator using EPA Form 8700-12.
• Within 90 days: Submit overdue biennial reports for 2019, 2021, and 2023.
• Within 365 days: Close and decommission the Neutralization Tank and associated piping to EPA closure performance standards.

Communities near extractive industry sites rarely receive enforcement updates proactively. If you live in northwestern Alaska, contact the Northwest Arctic Borough Assembly and ask what environmental monitoring commitments exist around the Red Dog Mine’s tailings impoundment. If you are a researcher, journalist, or advocate, FOIA EPA Region 10 for any environmental sampling data associated with this consent agreement. If you are a worker at the facility, you have the right under OSHA’s Hazard Communication Standard to know what chemicals you work around. National groups like Earthjustice, the Center for Biological Diversity, and the Native American Rights Fund have legal tools and experience with exactly this type of extractive-industry accountability in Indigenous communities. Local organizing and mutual aid between Inupiaq communities and environmental legal advocates is the most direct path to answers the EPA’s consent agreement did not require Teck to provide.
