Our Clients

We represent companies in a wide range of industry sectors, including oil and gas, energy, chemical, refining, manufacturing, construction and transportation, in environmental civil litigation matters in state and federal courts, as well as before environmental and safety regulatory agencies.

Our Services

Our Environmental and Workplace Safety practice understands the challenge that companies face when navigating federal, state and local environmental laws and regulations. We have a proven track record of resolving civil environmental litigation matters under the Clean Water Act (CWA), the Clean Air Act (CAA), the Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Occupational Safety and Health Act (OSH Act), Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), Migratory Bird Treaty Act (MBTA), the Endangered Species Act (ESA), National Environmental Policy Act (NEPA), California Environmental Quality Act (CEQA), and others.

Environmental Litigation

Katten represents clients at administrative hearings and public meetings before the US Environmental Protection Agency (EPA) and state, regional and local governmental agencies—including environmental, transportation, and planning agencies and city councils. We also litigate environmental permit appeals before federal and state environmental agencies and courts, and we have a particularly significant depth of experience handling contested permits in the state of Texas. Our team can quickly assess the case, consider alternative resolutions—including the prospects and risks of settlement or mediation—and, where necessary, litigate the matter to conclusion. With streamlined and cost-effective case management, our Environmental Litigation attorneys represent clients through every phase of an administrative or civil proceeding.

Civil Enforcement

Our team has a deep bench of former government environmental lawyers that understand the intricacies of environmental civil enforcement cases. Our experience covers the full spectrum of issues associated with environmental civil enforcement such as investigations and audits (including the risks and benefits of self-disclosure), the development of compliance programs, inspections, cost recovery actions, enforcement proceedings, defense of citizen suits, appellate advocacy, and environmental contract disputes, including environmental contractual indemnification and insurance recovery. Our team combines legal capabilities and technical know-how with practical litigation and trial experience to protect the interests of our clients. Beyond litigation, our team also has helped clients to negotiate reasonable civil settlements.


Katten has significant experience working on the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) or "Superfund," and state-equivalent Superfund cases. We assist clients in developing and implementing effective strategies to manage and mitigate potential liabilities associated with contaminated properties. We handle the full range of issues, including site investigation and remediation, Superfund litigation, cost recovery negotiations, and natural resource damages claims. We routinely defend our clients against federal and state claims, and provide counsel on Brownfields cleanups. We have guided clients through the Request For Information (RFI) process, and assisted clients with land use issues, including purchasing or developing a contaminated property where Superfund liability principles may apply. Our clients benefit from our extensive experience with EPA Regions across the United States and multiple state and local agencies, including the Texas Commission on Environmental Quality (TCEQ), California Department of Toxic Substances Control (DTSC) and the Regional Water Quality Control Boards.

Toxic Tort

Our attorneys represent companies and individuals such as corporate executives and other employees in actions triggered by any number of causes, including whistleblowers, citizen complaints, self-audits and disclosures, search warrants, grand jury subpoenas, and the alleged release of contaminants into air, soil and groundwater from the operation of fuel pipelines, landfills, underground storage tank systems, manufacturing processes, vessels, shipping terminals and pesticide application. These matters often involve claims of individuals, companies or neighborhoods seeking cost recovery and/or contribution, property damage, diminution in property value, economic and business losses, stigma, personal injury, wrongful death, fear of cancer, emotional distress, and medical monitoring. Our team quickly assesses the case, considers alternative resolutions and, if necessary, litigates the matter to conclusion. When possible, we seek to narrow the scope of complaints, as well as obtain summary judgment in related cases.

Our team includes attorneys with significant, hands-on experience, scientific and technical knowledge in environmental fields, and familiarity with insurance recovery and health and safety law practices. We have relationships with the preeminent experts in the fields of oncology, epidemiology, toxicology, potable water distribution, contaminant fate and transport, geology, hydrogeology, air dispersion and modeling, industrial practices, real estate valuation, and economics to support our legal strategies for our clients.

Citizen Suits

Katten has significant experience in defending against citizen suits under environmental laws, and when litigation cannot be avoided, we have a proven record in the court room. With governmental budgetary constraints, federal and state regulators frequently support citizen suits to alleviate the government’s enforcement burdens. Katten understands how to carefully navigate the procedural and strategic challenges inherent in citizen suits from more stringent notice requirements to fee provisions and costs incurred as well as sought. Our attorneys have effectively argued jurisdictional issues by relying on and differentiating recent EPA actions and court rulings. We also have guided clients in developing proactive procedures and policies to avoid the risks of citizen suits. Our deep understanding of environmental compliance, enforcement and litigation enables our attorneys to handle complex citizen suits.

Superior Court, Katten obtained dismissal of all claims.
  • Successful defense of one of the world's largest suppliers of fresh and prepared produce against allegations by more than 6,000 plaintiffs—former agricultural workers resident in Honduras, Panama, Nicaragua and Guatemala—that the use of nematode pesticides in foreign jurisdictions caused sterility and birth defects.
