As a partner in our Transportation and Environment practices, Joanne Rotondi focuses her practice on regulatory compliance, litigation, and environmental permitting.

Joanne guides clients through obtaining critical regulatory approvals such as vehicle and engine certifications and on-board diagnostic approvals, as well as complex permitting processes for large development projects, including liquefied natural gas terminals and deep-water ports, and has a talent for coordinating legal, expert, and client teams to achieve success.

With a deep understanding of the technical issues involved, she advises large automotive manufacturers and suppliers on emissions, fuel economy, and greenhouse gas issues at state and federal levels, in-use compliance and reporting requirements, and related policy and rulemaking efforts. She brings vast knowledge of every aspect of Clean Air Act mobile source regulation, as well as the Clean Water Act, National Environmental Policy Act, and endangered species matters, and taps into that knowledge for a wide range of clients including vehicle and heavy duty engine manufacturers. Her work includes obtaining critical approvals from both the U.S. EPA and California Air Resources Board for new motor vehicles and engines, and leading the team's efforts to provide business critical advice on the first ever export LNG deep-water port in the Gulf of Mexico.

Joanne serves on the EPA's Mobile Source Technical Review Subcommittee of the Clean Air Act Advisory Committee. This subcommittee includes industry, academic, public interest, and government representatives providing advice, counsel, and recommendations on the scientific and technical aspects of programs related to mobile source air pollution and motor fuels. The MSTRS workgroups address a wide range of issues and research areas, such as emissions modeling, air toxics, innovative and incentive-based transportation policies, on-board diagnostics, heavy-duty engines, and reformulated gasoline.
