Environmental Toxic Chemical Contamination Case Experience


The Hannon Law Firm, LLC has represented numerous individuals and businesses in landmark cases for both personal injury and property damage resulting from toxic chemicals. The Firm has pioneered groundbreaking approaches to protect and compensate its clients in trial courts and appeals courts. The Firm has 20 years of experience with toxic chemical exposure cases, including those involving: PFOAs and PFCs, lead, cadmium, asbestos, mold, industrial solvents, and above ground and underground storage tanks.

Jackson v. Unocal – Asbestos Contamination Class Action

In 2006, The Hannon Law Firm, LLC, with co-counsel, filed Jackson et al. v. Unocal et al., a lawsuit on behalf of approximately 500 property owners against Unocal Corporation and others for asbestos contamination in the soil in northeast Colorado caused by the removal of a pipeline and salvage operations connected with the pipeline. The class action lawsuit was certified on March 17, 2009. Unocal appealed the class certification. On October 31, 2011, the Supreme Court upheld the class certification and in doing so reaffirmed Colorado law supporting class certification. The negotiated settlement included a $32.5 million payment to the class and additional cleanup and testing requirements. The Final Fairness Hearing was held on January 24, 2013, and settlement was approved.

Orjias v. Louisiana-Pacific – Formaldehyde Air Emissions

In Orjias et al. v. Louisiana-Pacific, the Hannon Law Firm, LLC represented families who lived next to a waferboard facility which emitted formaldehyde, MDI and wood particulates. Several attorneys had rejected the suit before Kevin’s co-counsel agreed to take the case. Kevin’s clients suffered health and property damages and eventually had to move away from the pollution. The three week trial resulted a March 1992 jury verdict for $2.3 million, including $1.8 million in punitive damages. Evidence from that trial was used as part of the basis for action by the federal government against Louisiana-Pacific, which included the largest fine imposed by the U.S. EPA at the time, and criminal charges. The Orjias verdict was upheld in its entirety through the United States Supreme Court.

NWIS and NRRI v. Public Service Company of Colorado – Leaking Natural Gas Storage

In 1998, the Firm won a $1.8 million jury verdict on behalf of an owner of industrial property located next to the Leyden Underground Natural Gas Storage facility in Jefferson County operated by Public Service Company of Colorado. The award, which included $278,000 in punitive damages, proved a total loss in value of this 70 acre property due to the migration of natural gas from the Leyden storage facility. The Leyden Storage facility is the only facility for the underground storage of natural gas in the United States made from an abandoned coal mine. When Public Service then sought to take the client’s property away by condemning the property, the Firm also successfully defeated that action. In January, 2000, the verdict was affirmed in its entirety by the Colorado Court of Appeals. The Colorado Supreme Court refused to hear the request of Public Service to review the Court of Appeals’ decision. As a result of the publicity surrounding that decision, Public Service admitted to the leaks it had not previously disclosed and agreed to drop the operating pressure of the facility to reduce the migration of gas. Public Service eventually decommissioned this dangerous facility because of the publicity surrounding the case.

Doyle v. Fluor and Doe Run – Lead Smelter Class Action

The Hannon Law Firm, LLC has a special interest in protecting those who have been exposed to lead and has served as co-counsel in representing individuals whose properties are damaged by air and soil contamination from the Doe Run Smelter in Herculaneum, Missouri. St. Joe Lead Corporation, Fluor Corporation, and The Doe Run Corporation operated a lead smelting plant in the town of Herculaneum, Missouri. As a result, it poisoned hundreds of children, contaminated over 700 properties and put its workers at risk. Doe Run had violated the national lead standard in every quarter, except one, from 1978 through 2000. In 1993, the Missouri Department of Health concluded that there Ais a long term threat to public health around the Doe Run Smelter. The Hannon Law Firm, LLC filed the original case as Dixon v. Fluor and Doe Run in 1995, a class action for property damage and medical monitoring in Jefferson County. After a December 2000 hearing, a judge denied certification of class.

The Firm refiled the property damage class as Doyle, et al v. Fluor, et al in 2001. The case included Ira Rennert and Renco, Inc., the new Doe Run owner who had a reputation of buying distressed industrial companies. After 19 years of litigation, including four appeals, hundreds of depositions, and dozens of motions, the case settled on the eve of trial as pretrial rulings were issued. The property owners of Herculaneum finally achieved some measure of justice as a result of a $55 million settlement with Doe Run. The Doe Run Smelter ceased operations the last day it could under its settlement agreement with EPA on December 31, 2013. It was the last primary lead smelter in the United States.

Meyer v. Fluor and Doe Run – Medical Monitoring Class Action

The Firm has successfully prosecuted personal injury claims for Herculaneum children as a result of the damage from toxic lead. The Firm’s Meyer, et al. v. Fluor, et al. medical monitoring class action established groundbreaking standards for medical monitoring. The Firm also helped re-establish the law of corporate officer liability in the Missouri Supreme Court.

In addition to the Doyle and other lead smelter-related cases, the Firm has brought personal injury claims for damage arising out of exposure to toxic releases from the lead waste or chat piles in southeastern Missouri created from lead mining and milling. Separately the Firm has prosecuted lead paint exposure cases for individual children.

Hazardous Products Case Experience


The Hannon Law Firm, LLC represents individuals against product manufacturers for negligent design and manufacture. The Firm has successfully brought claims against the manufacturers of medical products, bicycles, food processors, and other products. For example, in 1996 the Firm successfully completed an action against General Motors, alleging defects in warnings related to and the design of the front passenger seat and seat restraint system of a 1992 Geo Prism. The Firm’s client had suffered catastrophic injuries including both brain and spinal cord injuries. General Motors settled the case just hours before a hearing to award sanctions for GM’s failure to produce critical documents. The settlement provided compensation for the lifetime needs and damages for the Firm’s client. The Firm has represented workers against chemical manufacturers for negligent warnings, instructions, and testing. The Firm has represented persons harmed by defective medical implants.

Notable Cases

Automobile Restraint Defects

Our firm and our co-counsel successfully represented a client against a major U.S. automobile manufacturer alleging defects in warnings related to and the design of the front passenger seat restraint system. The vehicle had a two-point automatic seat belt with no passenger side airbag, and our client’s seat was reclined at the time of the accident. Our client had suffered catastrophic injuries including both brain and spinal cord injuries. The auto manufacturer required the amount of the settlement to be held confidential.

Spinal Fusion Implants

Our firm represented a client against a major U.S. medical device manufacturer for negligent manufacture and design of medical implants placed after spinal fusion. The implants both broke in our client’s back. Our evidence included inadequate finishing and alternative design and warnings. The manufacturer required the amount of the settlement to be held confidential.

Brain & Spinal Cord Injuries Case Experience


The Firm also represents persons who have sustained brain and spinal cord injuries, whether from automobile accidents, falls, or other circumstances. Kevin Hannon has received special training in the mechanisms of injury, care and treatment, and special economic needs of spinal cord and head injured persons and has presented lectures in this specialized area.

Notable Cases

Automobile Collisions

We have represented restrained passengers in a variety of car and truck collisions, suffering brain and spinal injuries, other physical injuries and emotional injuries and economic loss.

Medical Transport

We represented a retired gentleman who was dropped while being transported by medical transport personnel down stairs in his home. He suffered loss of consciousness, altered taste and smell, severe memory loss and depression.

Car Collisions & Personal Injury Case Experience


The Hannon Law Firm, LLC’s clients include persons injured in automobile collisions and premises incidents, those injured by the negligence of doctors, and those suffering other physical and economic damage. As in example, in May, 2000, the Firm obtained a $535,000 judgment for an auto accident victim after rejecting the highest offer of $25,000 by the defendant’s insurer State Farm.

Notable Cases

Auto Collisions

We annually represent numerous victims of automobile collisions, with any number of vehicles, from any angle of impact, under a variety of weather conditions. Injuries have included fractures, brain injuries, paralysis, cervical strain, severe scarring and others. We have successful received recovery for lost wages, medical expenses, loss of earning capacity, permanent disability, loss of enjoyment of life, pain and suffering and other serious impacts on our clients’ lives.

Anhydrous Ammonia Spill

We successfully represented a woman who was physically and psychologically injured from an anhydrous ammonia spill. A tanker truck axle’s components had been mismatched. The axle split in two, cutting a hose which leaked thousands of gallons of ammonia in a toxic cloud. The cloud trapped our client in her home, and she eventually was yanked through a window to safety.

Physical Violence

We represented a woman held captive by her boyfriend and severely beaten, who was taken to the boyfriend’s parents house by the boyfriend and his mother. Our client received brain damage and significant psychological trauma. The case resulted in a trust established to help her return to an active life.

Insurance Bad Faith Case Experience


Another area of the Firm’s practice is representing individuals and businesses against insurers for their failure to pay insurance benefits, or “bad faith.” The Firm has successfully tried and settled cases in which insurers have failed to pay automobile benefits, medical benefits, and liability coverage and when insurers have failed to defend their policyholders. Kevin Hannon has been qualified in Denver District Court as an expert to testify on insurance issues and has lectured on insurance law.

Bernhard v. Farmers Insurance – We received a verdict at trial for a woman who caused an accident who was subsequently sued. Farmers unreasonably failed to settle the claim against our client, resulting in a personal judgment against her. The case establishes appellate law that insurers could not make a late offer of policy limits and escape liability for their delay in settling. We were unsuccessful in convincing the Colorado Supreme Court that the insurance company should pay the attorney fees the insured has to spend to protect herself when an insurance company unreasonably fails to settle a case.

Montgomery v. St. Paul – We represented owners of a geodesic wood shake home damaged by a hail storm. The adjuster for St. Paul insurance did not properly inspect the damage and offered less than $10,000 for repairs. The case settled for $200,000 before trial.
