How Lima Refining Company’s Alleged Negligence Exposed an Ohio Town to Benzene.

Breathing Poison for Profit

TL;DR

  • Lima Refining Company violated federal benzene emissions standards, VOC pollution rules, and its own operating permit at its Lima, Ohio refinery.
  • The U.S. Department of Justice filed a lawsuit against Lima Refining Company and lodged a proposed settlement on September 27, 2024.
  • The company will pay a $19 million civil penalty ($19 million is roughly what 380 average American workers earn in an entire lifetime of labor) to resolve the claims.
  • As part of the settlement, Lima Refining Company must install six community air monitoring stations and post the data publicly, a protection residents should have had from day one.
  • The company also failed the baseline legal requirement to use “good air pollution control practices,” a standard so basic it is essentially the regulatory floor.

The specific federal violations listed in the complaint reveal a company that ignored every layer of the law at once. The full breakdown is in Legal Receipts.

A refinery in Lima, Ohio spent years releasing benzene, a chemical the federal government classifies as a known human carcinogen, into the air that surrounding residents had no choice but to breathe.


What Lima Refining Company Actually Did

The U.S. Department of Justice, acting on behalf of the Environmental Protection Agency, filed a complaint against Lima Refining Company alleging the company violated the National Air Emission Standards for Hazardous Air Pollutants (NESHAP) specifically governing benzene waste operations. Benzene is a colorless, flammable chemical that causes leukemia and other blood cancers in humans. Lima Refining Company allowed it to escape from its refinery’s waste systems in amounts that violated federal law.

The violations did not stop at benzene. The company also violated the New Source Performance Standards for volatile organic compound (VOC) emissions from refinery wastewater systems. VOCs contribute to the formation of ground-level ozone, which damages lung tissue and triggers asthma attacks, particularly in children and elderly people.

On top of both of those violations, the company broke its own Title V operating permit, which is the foundational environmental operating license every major industrial facility is required to hold and comply with. Breaking your own permit means the facility failed to meet even the basic standards it promised regulators it would meet when it was granted permission to operate.

“The Complaint alleges that Defendant violated… the general requirement to use good air pollution control practices.”

A requirement so basic it is essentially the legal floor. Lima Refining Company could not clear it.

The DOJ’s proposed Consent Decree, lodged on September 27, 2024, requires Lima Refining Company to install a flash column, a piece of equipment designed to separate and capture pollutants before they escape into the atmosphere. This is technology the company could have installed proactively, years earlier. Instead, it took a federal lawsuit to make it happen.

The settlement also mandates enhanced monitoring and repairs throughout the facility. The company must install six air monitoring stations in the surrounding community and post the data publicly. The people of Lima, Ohio are only getting real-time data about what they are breathing because a court ordered it.

The Non-Financial Ledger

Human Cost

The people who live near the Lima Refining Company facility in Lima, Ohio did not sign up to be neighbors to a benzene-releasing operation. They woke up in the morning in their homes, sent their kids to school, opened their windows in summer, and breathed air that a federal agency ultimately concluded was laced with hazardous pollutants that violated federal law. The company’s violations were not a one-time accident. The breadth of the complaint, covering benzene waste standards, VOC emission standards, permit violations, and the failure to follow basic pollution control practices, describes an operation where multiple layers of legal protection failed simultaneously.

Benzene does not announce itself. It is colorless. It has a mild, sweet odor that most people would not identify as dangerous. A parent pushing a stroller past the refinery perimeter would not know. A child playing outside would not know. An elderly neighbor tending a garden would not know. The communities living downwind of industrial facilities routinely absorb the cost of corporate non-compliance with their bodies, and the exposure registers years or decades later as elevated cancer rates, unexplained blood disorders, and medical bills that no consent decree can cover.

What the settlement requires reveals exactly what the community was denied for the duration of the violations. Six air monitoring stations, publicly reporting real-time data, were deemed necessary enough to include as a mandatory remedy. That means during the period of violations, the surrounding community had no independent, publicly accessible way to know what concentrations of pollutants they were being exposed to in real time. The monitoring was not there. The data was not public. The accountability was absent.

The requirement for Lima Refining Company to install a flash column and conduct enhanced monitoring and repairs reads, in practical terms, as a list of things the company should have already been doing. These are not novel technologies or unreasonable demands. They are the basic infrastructure of responsible refinery operation. The community of Lima, Ohio waited for a federal lawsuit to arrive before those basics became non-negotiable. That waiting period, whatever its duration, is the real cost that no $19 million figure can fully account for.

Societal Impact Mapping

Environmental Degradation

Air Quality

Lima Refining Company violated benzene waste emission standards and VOC emission standards from refinery wastewater systems at the same time. Wastewater systems at refineries handle large volumes of contaminated liquid, and when VOC controls on those systems fail, volatile compounds escape directly into the surrounding atmosphere at ground level. This is among the most direct forms of industrial air pollution, because the emissions occur close to where people live and breathe, not from a tall stack that disperses pollutants over a wider area.

The requirement to install a flash column as part of the settlement remedy confirms that the existing vapor control infrastructure at the refinery was insufficient to meet legal standards. A flash column is designed to separate dissolved gases and volatile compounds from liquid streams before they can evaporate into the open air. Its absence, or its inadequacy, during the period of violations contributed directly to the illegal release of hazardous and volatile pollutants into the Lima, Ohio environment.

The mandate for six community air monitoring stations represents a direct acknowledgment that the surrounding area lacked adequate environmental surveillance during the violation period. Ambient air quality monitoring in the neighborhoods immediately adjacent to industrial facilities is the first line of defense for public health. Lima Refining Company’s operation proceeded without this community-level accountability infrastructure in place.

Public Health

Benzene Exposure

Benzene is not a borderline carcinogen or a substance where the science is uncertain. The International Agency for Research on Cancer and the U.S. EPA both classify it as a known human carcinogen, meaning sufficient evidence exists that benzene causes cancer in humans. It specifically causes leukemia and other blood cancers. The federal standards Lima Refining Company violated, the National Emission Standards for Hazardous Air Pollutants for benzene waste operations, exist precisely because benzene exposure at industrial facility boundaries poses a quantifiable, documented risk of cancer to neighboring populations.

VOC emissions carry their own distinct public health burden. Ground-level ozone formed from VOC reactions with sunlight triggers respiratory distress, worsens asthma, reduces lung function, and causes particular harm to children, seniors, and people with pre-existing respiratory conditions. Lima, Ohio residents living near the refinery during the violation period faced both categories of risk: the direct cancer risk from benzene and the respiratory risk from VOC-driven ozone formation.

Economic Inequality

Who Pays the Real Price

A $19 million civil penalty (enough to cover 2,533 families’ health insurance premiums for a full year, or the equivalent of what 380 average American workers earn across their entire working lifetimes) sounds significant. The question that never appears in a consent decree is whether $19 million bears any relationship to what Lima Refining Company saved, earned, or avoided spending by not installing proper pollution controls in the first place. The fine is the floor, set by regulators. The profits are private.

Industrial facilities of the type and scale of an oil refinery are almost never sited next to wealthy neighborhoods. The populations living adjacent to facilities like the Lima Refinery disproportionately include lower-income households, communities of color, and people who lack the legal and financial resources to mount independent environmental enforcement actions. Those residents depend entirely on federal regulators to enforce the law on their behalf. When a refinery violates benzene standards and VOC standards and its own operating permit and the basic requirement for good pollution control practices, all at the same time, those residents bear the health consequences while the corporation pays a negotiated penalty years later.


The “Cost of a Life” Metric

$19,000,000

The civil penalty Lima Refining Company will pay to resolve years of illegal benzene and VOC emissions in Lima, Ohio.

That is the equivalent of what 380 average American workers earn across their entire lifetimes of labor. It is the cost of one year of health insurance for 2,533 families. It is the amount that could pay 10,000 families’ rent for almost two full years at the U.S. median rent.

The community gets air monitors. The company gets to keep operating.
