Katrina defends class and mass actions, citizen suits, and enforcement actions in state and federal trial and appellate courts. Her experience spans opposing class certification with strong expert and fact evidence, seeking dismissal of nuisance and other tort claims, challenging unreliable expert evidence, advocating for her clients before administrative agencies, and litigating agency approvals for projects.

Katrina also focuses on National Environmental Policy Act compliance and litigation, wetlands regulation under the Clean Water Act, federal species protection laws such as the Endangered Species Act, land use law, and New York’s environmental justice, climate, and permitting laws. She helps clients navigate multi-agency permitting processes for large interstate projects and work with state and federal regulators to achieve their project goals.

In advising clients, she draws on her experience with the U.S. Fish & Wildlife Service on national wildlife refuges in Arizona, Colorado, and Wyoming, and as a law clerk with the federal government. Before joining Beveridge & Diamond, Katrina clerked for the U.S. Department of Justice in the Environment & National Resources Division and the U.S. Environmental Protection Agency in the Office of Enforcement & Compliance Assurance, providing her insights into federal enforcement and agency decision-making.

Katrina’s experience includes:

• Successfully excluding expert evidence and defeating class certification in a lawsuit in federal court seeking medical monitoring and other damages allegedly caused by a fire.
• Defeating class certification in a breach of contract suit involving 20,000 commercial waste collection customers in Florida district court.
• Obtaining dismissal before class certification practice of three putative class actions alleging landfills emitted nuisance odors in New York state courts.
• Obtaining dismissal prior to discovery of six personal injury suits alleging harm from PFAS and other chemicals in New Jersey federal court.
• Defeating class certification in putative class actions in Pennsylvania and Louisiana federal courts alleging that a waste-to-energy facility and a landfill emitted nuisance odors.
