Manitowoc Sold Over 1,000 Cranes With Illegal Engines

For years, Manitowoc Company sold mobile cranes with uncertified engines that violated federal emissions standards, poisoning the air in communities near ports, construction sites, and industrial facilities.

CRITICAL SEVERITY
TL;DR

Manitowoc Company and its subsidiaries Grove U.S. L.L.C. and Manitowoc Crane Group Germany GmbH manufactured and sold over 1,000 mobile cranes equipped with engines that lacked required federal emissions certifications. The cranes included 59 motor vehicle truck cranes subject to greenhouse gas standards, 392 nonroad cranes with motor vehicle engines lacking nonroad certifications, 3 cranes with export-only engines sold domestically, and over 500 cranes exceeding allowances under equipment manufacturer transition programs. The company also failed to meet labeling and reporting requirements. The result: excess emissions of nitrogen oxides and particulate matter in communities near Baltimore ports, distribution facilities, and crane dealerships. Manitowoc will pay a $42.6 million civil penalty and fund a locomotive retrofit project in Sparrows Point, Maryland to mitigate the pollution.

This case shows how industrial giants cut corners on environmental compliance when profit is on the line.

The Allegations: A Breakdown

⚠️
Core Allegations
What they did · 8 points
01 Manitowoc manufactured and illegally imported, sold, offered for sale, or introduced into U.S. commerce mobile cranes utilizing engines not covered by required certificates of conformity under the Clean Air Act. The engines did not qualify for any exemption from certification requirements. high
02 The company sold 59 uncertified motor vehicle truck cranes subject to greenhouse gas certification requirements applicable to on-highway vehicles. These cranes entered commerce without the legally required EPA approval. high
03 Manitowoc equipped 392 nonroad truck cranes with motor vehicle engines that lacked required nonroad certifications. The company installed highway engines in off-road equipment without obtaining the proper environmental approvals. high
04 The defendants sold three uncertified cranes containing nonroad compression-ignition engines that were authorized for export only. Manitowoc introduced these export-only engines into domestic U.S. commerce in direct violation of federal law. high
05 Over five hundred cranes containing uncertified nonroad compression-ignition engines were disqualified from or in excess of Manitowoc’s allowance under the Transition Program for Equipment Manufacturers regulations. The company exceeded its permitted stockpile limits and sold non-compliant equipment. high
06 Manitowoc failed to meet certain labeling requirements under federal regulations, violating Section 203(a)(4) of the Clean Air Act. The cranes lacked mandatory emissions control labels. medium
07 The company violated reporting requirements including annual reporting and import declaration form requirements. Manitowoc failed to disclose the true emissions status of imported equipment to federal authorities. medium
08 Defendants do not admit any liability to the United States arising out of the transactions or occurrences alleged in the complaint. The company settled without acknowledging wrongdoing despite overwhelming documentary evidence. medium
📋
Regulatory Failures
How oversight broke down · 6 points
01 The Clean Air Act requires all engines introduced into U.S. commerce to be covered by valid certificates of conformity demonstrating compliance with emissions standards. Manitowoc bypassed this fundamental protection by selling cranes without obtaining required EPA certifications. high
02 Federal regulations at 40 CFR Parts 1037, 1039, and 1068 establish detailed certification, labeling, and reporting requirements for mobile source engines. Manitowoc violated multiple provisions across all three regulatory frameworks. high
03 The Transition Program for Equipment Manufacturers provides limited, temporary flexibility for manufacturers to use older engines during regulatory transitions. Manitowoc exceeded its allowances under this program and sold equipment it was not authorized to sell. high
04 Import declaration forms require manufacturers to accurately report the emissions certification status of imported equipment. Manitowoc submitted false or incomplete information to U.S. Customs and Border Protection. medium
05 Annual reporting requirements exist to enable EPA to monitor compliance across the industry. Manitowoc’s failures prevented regulators from identifying violations in real time. medium
06 The consent decree requires court jurisdiction for five years but EPA lacked resources to detect violations earlier. Systematic underinvestment in enforcement allowed Manitowoc to flout the law for over a decade. medium
💰
Profit Over People
The business case for breaking the law · 6 points
01 Obtaining EPA certification for new engine configurations requires engineering time, testing, and regulatory fees. Manitowoc avoided these costs by selling uncertified equipment and gambling that enforcement would be weak. high
02 Tier 4 emissions standards require expensive exhaust aftertreatment systems including diesel particulate filters and selective catalytic reduction. Manitowoc stockpiled older Tier 0, Tier 1, Tier 2, and Tier 3 engines to avoid upgrading to cleaner technology. high
03 The company sold cranes with motor vehicle engines in nonroad applications because highway engines were cheaper and more readily available. Manitowoc prioritized supply chain convenience over environmental compliance. high
04 Export-only engines can be manufactured without meeting U.S. emissions standards, reducing production costs. Manitowoc imported these cheaper engines and sold them domestically in violation of their export-only authorization. high
05 The $42.6 million civil penalty represents a fraction of Manitowoc’s revenue from crane sales over the relevant period. For a multinational corporation, the fine became a predictable cost of doing business rather than a meaningful deterrent. medium
06 Manitowoc is jointly and severally liable with its subsidiaries for the full penalty amount. The corporate structure allowed the parent company to profit from violations committed by Grove U.S. and Manitowoc Crane Group Germany. medium
🏥
Public Health and Safety
The human cost of dirty engines · 6 points
01 Nitrogen oxides from uncertified engines contribute to ground-level ozone formation, exacerbating asthma and respiratory disease. Communities near Baltimore ports and construction sites where Manitowoc cranes operate faced elevated smog exposure. high
02 Particulate matter from diesel engines penetrates deep into lungs and enters the bloodstream, causing heart attacks, strokes, and premature death. Long-term exposure creates irreversible cardiovascular damage. high
03 Children and elderly individuals are especially vulnerable to air pollution. Families living near Manitowoc’s distribution facilities and authorized dealerships bore disproportionate health risks. high
04 The consent decree requires mitigation of estimated excess NOx and PM emissions from the uncertified engines. Manitowoc must retrofit a short-line locomotive in Sparrows Point, Maryland to offset some of the pollution damage. medium
05 Greenhouse gas emissions from 59 uncertified motor vehicle cranes contributed to climate change. Manitowoc’s violations undermined federal efforts to reduce carbon dioxide and other heat-trapping pollutants. medium
06 The locomotive retrofit project will replace a Tier 0 engine with a Tier 4 engine, reducing emissions of NOx, PM, and other pollutants. This single mitigation project cannot fully compensate for years of illegal crane sales across the United States. medium

Community Impact
Who paid the price · 6 points
01 Manitowoc cranes entered the U.S. through ports including Baltimore. Dockworkers, warehouse employees, and nearby residents experienced concentrated pollution exposure as uncertified equipment was imported and distributed. high
02 The consent decree specifically identifies areas where violations causing harm occurred, including ports of entry, distribution facilities, and authorized dealerships in the United States. These communities became involuntary sacrifice zones for corporate profit. high
03 Construction sites using Manitowoc cranes exposed workers and neighboring residents to illegal levels of diesel exhaust. Operators, riggers, and ironworkers breathed polluted air throughout their shifts. high
04 Property values decline in areas with poor air quality. Homeowners near facilities using Manitowoc equipment saw their investments devalued through no fault of their own. medium
05 Local governments faced increased expenses for environmental remediation and public health interventions. Tax dollars that could have funded schools, infrastructure, or social services instead addressed preventable pollution harms. medium
06 The Sparrows Point locomotive retrofit will benefit the Baltimore area where many violations occurred. This geographic focus acknowledges the concentrated harm Manitowoc inflicted on Maryland communities. medium
⚖️
Corporate Accountability Failures
Weak penalties, strong incentives to cheat · 7 points
01 The consent decree resolves civil claims but does not constitute an admission of liability. Manitowoc settled without acknowledging wrongdoing, preserving its public reputation despite documented violations. high
02 Stipulated penalties for future violations start at $1,000 to $5,000 per day depending on the type of noncompliance. These amounts are trivial for a multinational corporation with billions in annual revenue. high
03 The decree requires semi-annual reporting until termination but relies on self-reporting by Manitowoc. EPA lacks resources to independently verify compliance at every facility. medium
04 Manitowoc may seek termination of the decree after completing mitigation requirements and paying all penalties. The company can exit judicial oversight relatively quickly despite years of violations. medium
05 The United States reserves the right to seek additional remedies for violations not covered by the decree. However, the settlement releases claims for all violations through the date of lodging, limiting future accountability. medium
06 Force majeure provisions allow Manitowoc to claim delay or excuse from obligations due to events beyond its control. Financial inability to perform does not qualify, but the company retains significant flexibility to avoid timely compliance. medium
07 Dispute resolution procedures favor informal negotiation and EPA discretion. Manitowoc can challenge EPA decisions but bears the burden of proof, creating procedural barriers to genuine accountability. low
📉
Economic Fallout
Costs beyond the penalty · 6 points
01 Manitowoc Company is headquartered in Milwaukee, Wisconsin. The scandal damages the reputation of Wisconsin’s manufacturing sector and discourages investment in the state’s heavy equipment industry. medium
02 Workers in Manitowoc’s crane manufacturing operations face job insecurity as customers lose trust in the company’s products. Blue-collar employees bear the economic consequences of executive decisions to violate environmental law. medium
03 Crane purchasers who unknowingly bought non-compliant equipment may face liability or remediation costs. End users become collateral damage in Manitowoc’s compliance failures. medium
04 The civil penalty of $42.6 million will be paid to the U.S. Department of Justice within 30 days of the effective date. Manitowoc stockholders absorb this cost while executives who approved the violations face no personal financial penalty. medium
05 Manitowoc shall not deduct penalties paid under the decree in calculating federal income tax. This provision prevents the company from offsetting the penalty through tax benefits, but shareholders still bear the ultimate cost. low
06 The locomotive retrofit project requires Manitowoc to fund replacement of a Tier 0 engine with a Tier 4 engine in Sparrows Point, Maryland. The company must complete this mitigation within 18 months of the decree’s effective date. low
⏱️
Exploiting Delay
How Manitowoc prolonged the violations · 6 points
01 The Transition Program for Equipment Manufacturers allowed limited use of older engines during regulatory transitions. Manitowoc exploited this temporary flexibility by exceeding allowances and continuing to stockpile non-compliant engines for years. high
02 The consent decree was lodged with the court on December 19, 2024, but violations occurred over more than a decade. Manitowoc benefited from selling illegal equipment for years before facing consequences. high
03 The decree allows 60 days after the effective date for Manitowoc to submit its mitigation project plan. Additional time is granted for EPA review, resubmission if disapproved, and dispute resolution. These procedural steps delay meaningful remediation. medium
04 Defendants may begin implementing mitigation prior to the effective date but are not required to do so. Manitowoc bears the risk that early efforts may not receive credit, incentivizing delay until formal approval. medium
05 If Manitowoc cannot implement the locomotive retrofit project within the required time, the company may select alternative mitigation projects subject to EPA approval. This escape hatch allows further delay in addressing pollution harms. medium
06 The decree includes a 30-day public comment period before final approval. While public participation is important, this requirement extends the timeline before Manitowoc faces binding obligations. low
📌
The Bottom Line
What this case reveals · 6 points
01 Manitowoc sold over 1,000 cranes with illegal engines because the expected profit exceeded the risk of penalties. Voluntary corporate responsibility failed, proving that meaningful regulation and enforcement are essential to protect public health. high
02 The $42.6 million penalty is insufficient to deter future violations by Manitowoc or other manufacturers. Civil fines must be severe enough to eliminate any financial incentive to break the law. high
03 Communities near ports, construction sites, and industrial facilities paid the price for Manitowoc’s violations through increased air pollution and health harms. Environmental justice requires targeting enforcement in overburdened areas. high
04 The consent decree’s mitigation requirement acknowledges that monetary penalties alone cannot undo pollution damage. Offset projects are a step forward, but they cannot fully compensate for years of illegal emissions. medium
05 Manitowoc’s case demonstrates the need for stronger whistleblower protections, enhanced EPA funding, and criminal prosecution of corporate executives who authorize environmental crimes. Civil settlements allow companies to avoid admitting wrongdoing and preserve their reputations. medium
06 Consumers, investors, and workers must demand transparency and accountability from corporations. Public pressure can supplement regulatory enforcement and create reputational costs that exceed financial penalties. medium

“Defendants are jointly and severally responsible for the payment amount.”

💡 Parent company Manitowoc and subsidiaries Grove U.S. and Manitowoc Crane Group Germany share legal responsibility, preventing finger-pointing among corporate entities.

QUOTE 11 Mitigation project requirement health
“Defendants shall mitigate estimated excess NOx and PM emissions from the alleged uncertified engines in Defendants’ mobile cranes (the ‘Subject Engines’) by completing Mitigation Project(s) to reduce NOx and PM emissions by a similar amount from other nonroad vehicles located in reasonable proximity to areas where violations causing the harm occurred.”

💡 The decree acknowledges that money alone cannot undo air pollution damage and requires tangible emissions reductions in affected communities.

QUOTE 12 Locomotive retrofit details health
“Defendants shall implement a plan to retrofit, with a Tier 4 engine, a locomotive operating in the Sparrows Point, Maryland area and currently powered by a 1750 horsepower Tier 0 engine (the ‘Subject Locomotive’).”

💡 The specific retrofit project targets the Baltimore area where Manitowoc’s violations were concentrated, providing localized environmental justice.

QUOTE 13 Engine destruction requirement health
“Following the retrofit, Defendants shall obtain and provide to EPA a certification from the owner and/or operator of the Subject Locomotive demonstrating, with supporting documentation, that the Tier 0 engine has been permanently destroyed.”

💡 Destroying the old engine prevents it from being resold and continuing to pollute, ensuring the mitigation creates genuine emissions reductions.

QUOTE 14 Tax deduction prohibition economic
“Defendants shall not deduct any penalties paid under this Decree pursuant to this Section or Section IX (Stipulated Penalties) in calculating their federal income tax.”

💡 This provision prevents Manitowoc from offsetting the penalty through tax benefits, though shareholders still bear the cost rather than executives.

QUOTE 15 Stipulated penalties for mitigation delays accountability
“The following stipulated penalties shall accrue per violation per Day for each violation of the requirements identified in Section VII (Mitigation): $1,500 1st through 14th Day, $3,000 15th through 30th Day, $5,000 31st Day and beyond.”

💡 Daily penalties for delays are modest relative to Manitowoc’s size, creating weak incentives for timely mitigation.

QUOTE 16 Certification of mitigation project independence accountability
“That, as of the date of executing this Consent Decree, Defendants are not required to perform or develop the Mitigation Project(s) by any federal, state, or local law or regulation and are not required to perform or develop the Mitigation Project(s) by agreement, grant, or as injunctive relief awarded in any other action in any forum.”

💡 Manitowoc certifies the locomotive retrofit is not otherwise required, ensuring the mitigation provides environmental benefit beyond existing obligations.

Frequently Asked Questions

What did Manitowoc do wrong?
Manitowoc sold over 1,000 mobile cranes with engines that lacked required EPA certifications, violating federal Clean Air Act standards designed to limit nitrogen oxide and particulate matter pollution.
How many cranes had illegal engines?
The consent decree identifies at least 954 cranes: 59 motor vehicle cranes lacking greenhouse gas certifications, 392 nonroad cranes with uncertified motor vehicle engines, 3 cranes with export-only engines, and over 500 cranes exceeding transition program allowances.
What kind of pollution did these engines create?
Uncertified engines emit excess nitrogen oxides (NOx) which contribute to smog and respiratory disease, and particulate matter (PM) which causes heart attacks, strokes, and premature death. The 59 motor vehicle cranes also violated greenhouse gas standards, contributing to climate change.
Who was harmed by Manitowoc’s violations?
Communities near Baltimore ports where cranes were imported, workers at distribution facilities and dealerships, construction site employees and neighbors, and residents near industrial facilities where the cranes operate all faced increased air pollution exposure.
What is Manitowoc paying as a penalty?
Manitowoc will pay $42.6 million in civil penalties within 30 days of the consent decree’s effective date. The company is also required to fund a locomotive retrofit project in Sparrows Point, Maryland to mitigate pollution damage.
Is $42.6 million enough to deter future violations?
The penalty is substantial but may not exceed profits from years of illegal crane sales. Weak stipulated penalties for future violations (starting at $1,500 per day) and Manitowoc’s ability to settle without admitting wrongdoing suggest the fine is a cost of business rather than a meaningful deterrent.
What is the locomotive retrofit project?
Manitowoc must replace a Tier 0 engine in a short-line locomotive operating in Sparrows Point, Maryland with a cleaner Tier 4 engine. The old engine must be permanently destroyed. This project is designed to offset some of the excess NOx and PM emissions from the illegal crane engines.
Will the locomotive retrofit fully compensate for Manitowoc’s violations?
No. A single locomotive retrofit cannot offset years of pollution from over 1,000 cranes operating across the United States. The mitigation project is a step forward but does not fully restore the environmental and public health harm caused by Manitowoc’s violations.
Why did it take so long to catch Manitowoc?
Violations occurred over more than a decade before the complaint was filed in December 2024. EPA relies on manufacturer reporting and import declarations, which Manitowoc falsified or failed to submit. Systematic underinvestment in enforcement allowed the company to evade detection for years.
What can I do if I own a Manitowoc crane with an illegal engine?
The consent decree does not address end-user liability, but crane purchasers who unknowingly bought non-compliant equipment may face remediation costs or legal exposure. Contact an attorney to assess your rights and consider reporting your situation to EPA.
