Julia Mata’s practice focuses on compliance and litigation matters arising under state and federal environmental laws, as well as state statutory and common law claims. She advises and defends clients in a broad range of disputes, including environmental enforcement, complex toxic tort, product liability, Prop 65, and groundwater contamination actions.

Julia also has extensive experience with the compliance issues associated with transportation and disposal of solid and hazardous waste, as well as safe storage of oil and hazardous materials. She regularly advises clients on compliance with state and local environmental laws, including those overseen by the State Water Resources Control Board and California’s Unified Program Agencies.

While Julia most often represents clients in defense of claims brought against them, she has also represented large companies and individuals as plaintiffs in cases ranging from tort and fraud claims to constitutional challenges of local ordinances. Julia has tried cases in both state and federal courts, and successfully argued summary judgment and other pre-trial motions for her clients.

Julia’s clients include energy companies, transportation companies, property owners, and manufacturers and distributors of consumer products, chemicals, and beauty products throughout the United States and beyond. She has also represented low-income clients as part of the Federal Pro Bono Project and the San Francisco Bar Association’s Justice & Diversity Center.

Prior to beginning her legal career, Julia interned at the San Francisco District Attorney’s Office and environmental regulatory agencies such as the U.S. Department of Justice, Environment and Natural Resources Division and the Bay Conservation & Development Commission. Julia also served as an editor of UC Hastings College of the Law’s environmental law journal and competed with honors in the school’s negotiation and mediation competition team.

As a college student, I remember thinking I wanted to pursue a career in the environment, economics, or law. Now my practice is a great blend of all those interests. Behind my concern about climate change and pollution was an endless set of questions about how societies make decisions about resources and the risks inherent in our modern life. So much of environmental law and litigation is about deciding what level of risk is acceptable, how to avoid harm, and who should pay to address those harms and risks. I find these questions fascinating, and am grateful for the opportunity to help my clients solve the many complex environmental problems they face.
