A biotech company that makes products for medical diagnostics stored open containers of ignitable and toxic solvents, left mercury-containing lamp shards on an outdoor surface, and skipped mandatory air safety checks 32 times over three years, then settled every charge with federal regulators for less than the cost of a used Tesla.

The Company Behind the Lab Coat

Biosearch Technologies, Inc. operates a manufacturing facility at 2199 S. McDowell Blvd in Petaluma, California. The company manufactures custom oligonucleotides and synthesizes reagents for medical diagnostics, research, and applied markets. That means its products help doctors run tests. Its waste handling, however, was another matter entirely.

On September 30, 2022, EPA Region 9 conducted a compliance evaluation inspection at the facility. What inspectors found resulted in seven separate violation counts under the Resource Conservation and Recovery Act, the federal law that governs how hazardous waste must be handled, stored, and tracked. The settlement was not finalized until December 12, 2025, meaning this situation dragged on for over three years before the company paid a single dollar.

Biosearch Technologies is operated under the umbrella of LGC Diagnostics and Genomics. The settlement was signed by Steve Cooper, Vice President and Head of Operations, and correspondence was directed to Rob McLeod, Director of Global Environmental Health and Safety at LGC Diagnostics and Genomics.

The Non-Financial Ledger

What the fine can never repay.

When “Routine Compliance” Becomes a Threat to People Nearby

Biosearch Technologies manufactures products for medical diagnostics. The public is supposed to be able to trust that a company in the business of supporting healthcare also handles its own toxic byproducts responsibly. What the EPA found when inspectors walked through the Petaluma facility in September 2022 shattered that expectation. Two 55-gallon drums of ignitable and listed hazardous waste, each capable of releasing volatile organic compounds, sat open when no one was adding or removing material. That is not a paperwork error. That is a fire hazard and an air quality event waiting to happen inside a building where workers show up every single day.

The people most exposed to the consequences of these violations are not shareholders or executives. They are the workers on the facility floor, the neighbors in Petaluma’s surrounding residential and agricultural communities, and the emergency responders who would be the first called if an open container of ignitable solvent caught a spark. None of them received notice. None of them received compensation. None of them are named in this settlement. The document concerns itself entirely with the company’s liability, not the community’s safety.

The hazardous waste codes documented at this facility tell a specific story about chemical risk. The waste codes include D001 (ignitable), D002 (corrosive), D038 (a specific chemical hazard classification), F002 (spent halogenated solvents including chemicals like methylene chloride and chloroform), F003 (spent non-halogenated solvents including acetone and xylene), and F005 (another category of spent non-halogenated solvents). Among the specific chemicals named: hydrofluoric acid, stored in small containers, at least one of which exceeded the 90-day accumulation limit, and at least two others with no accumulation date marked at all. Hydrofluoric acid does not announce itself. It penetrates skin without immediate pain, then destroys tissue and bone from inside, disrupting calcium and potassium levels in the blood in ways that can cause cardiac arrest hours after exposure.

Then there is the matter of the broken lamps. EPA inspectors found broken shards of glass from shattered mercury-containing lamps sitting in an outdoor area of the facility. The law requires immediate cleanup and secure containment of any broken universal waste lamp. Biosearch Technologies failed to do that. Mercury vapor, released from broken fluorescent lamps, is a potent neurotoxin. Chronic low-level exposure causes damage to the brain, kidneys, and lungs. The shards were not cleaned up before the inspection. The inspection is what finally forced the issue. Without that government visit, there is no reason to believe anything would have changed.

The recordkeeping failures compound everything. Air monitoring for equipment leaks is not a bureaucratic technicality. When pumps and valves handle solvents with organic concentrations above 10% by weight, federal law mandates monthly leak detection monitoring precisely because invisible vapor releases accumulate in workspaces and surrounding air. Biosearch Technologies skipped this monitoring at least five times. Worse, they failed to keep the records of leak detection monitoring on at least 32 occasions between September 2019 and the inspection date. That is not a lapse. That is a pattern covering three years of operations, during which no one in management apparently found the time to document whether the air around their solvent tanks was safe to breathe.

Societal Impact Mapping

Environmental Degradation: Mercury on the Ground, Solvents in the Air

The outdoor mercury lamp shards are the most visible environmental violation in this case. Mercury is a persistent bioaccumulative toxin. It does not degrade. It settles into soil, washes into stormwater systems, and enters the food chain. Petaluma sits in Sonoma County, a region with significant agricultural activity, wetland ecosystems, and proximity to the Petaluma River watershed. The EPA’s own requirement to immediately clean up broken mercury-containing lamps exists precisely because of how quickly and permanently mercury can move from a broken glass shard into surrounding environmental systems. Biosearch Technologies failed to perform that cleanup before the inspection.

The solvent management violations compound the environmental picture. The Solvent Totes at the facility held hazardous waste with organic concentrations of at least 10% by weight, and the pumps and valves handling those totes were legally required to be monitored monthly for leaks. When those monthly checks do not happen, and when the records to prove they happened are also missing, there is no defensible way to know whether volatile organic compounds were releasing into the facility air or surrounding environment over the three years this pattern persisted. VOC releases contribute to ground-level ozone formation, respiratory illness, and long-term soil contamination. The absence of monitoring records is not evidence that nothing leaked. It is evidence that nobody was checking.

Public Health: Workers First, Community Second, Nobody Warned

Hydrofluoric acid deserves specific attention because its risks are not intuitive. Unlike most acids, it does not immediately cause burning pain at the site of contact. It penetrates skin silently, traveling to underlying tissue where it reacts with calcium and magnesium in the body, causing cellular destruction, bone damage, and potentially fatal electrolyte disruption. Systemic toxicity from even small skin exposures has caused deaths. Federal hazardous waste law limits storage of this substance to 90 days without a permit precisely because the longer it sits improperly managed, the greater the risk of accidental exposure. The EPA found at least one container over that limit, and multiple others with no tracking dates at all. No one can retroactively determine how long those containers had been sitting.

The open 55-gallon drums of ignitable solvents present an acute fire and inhalation risk. Ignitable hazardous waste, designated D001, includes substances with flash points below 140 degrees Fahrenheit. Open containers in a working facility expose employees to solvent vapors, which accumulate in enclosed spaces, displace oxygen, and create explosion hazards. The EPA regulation requiring these containers to remain closed except when waste is actively being added or removed is not paperwork. It is the minimum standard required to keep workers alive. Biosearch Technologies violated it, and the workers who were present in that facility had no way of knowing their employer was not meeting the baseline legal requirement for their safety.

Economic Inequality: The Fine That Means Nothing

The $53,572 ($53,572 is approximately equal to one year of full-time earnings at California’s minimum wage) penalty covers seven violations spanning at least three years of documented non-compliance. To put this in corporate terms: this is the kind of fine a mid-size company accounts for in a single rounding error on a quarterly earnings call. LGC Diagnostics and Genomics, the parent organization under which Biosearch Technologies operates, is a global life sciences company. The settlement imposes no structural accountability, no requirement to compensate affected workers or community members, and no acknowledgment from the company that any of the alleged violations actually occurred.

The company “neither admits nor denies” the specific factual allegations in the settlement. That phrase, repeated in consent agreements across every industry, is a legal mechanism that allows corporations to pay a fine and walk away without creating any record that could be used against them in future civil litigation. If a Petaluma worker developed a respiratory condition, or a neighbor found contamination in their soil, the settlement they are holding in their hands provides no legal hook. The company paid, and the slate is wiped clean. The fine does not scale to the size of the company, the duration of the violations, or the potential harm caused. It scales to what the EPA and the company agreed was acceptable to both parties.

What You Can Actually Do

If you live or work near 2199 S. McDowell Blvd in Petaluma, California, you have the right to request copies of EPA inspection reports, monitoring submissions, and compliance certifications under the Freedom of Information Act. Community members can file complaints with California DTSC and Cal/OSHA if they observe ongoing hazardous waste mismanagement. Environmental justice organizations in Sonoma County, mutual aid networks, and local labor unions are the fastest routes to organized, sustained pressure on both the company and its regulators. EPA settlements only mean something if communities hold the enforcers accountable for following through. For one year following this settlement, Biosearch Technologies is required to submit quarterly air monitoring data to EPA. That data will become public record. Make them show their work.
