Todd is a partner and the administrative head of the firm's environmental attorneys. He is also a member of the firm's Global Energy and Natural Resources Practice Group. His practice covers a broad array of environmental and energy services, including litigation, regulatory counseling and negotiating corporate and real estate transactions with complex environmental issues. He regularly represents clients before federal and state agencies on a variety of hazardous waste, water, air and environmental impact/land use issues.
Much of Todd's practice focuses on three areas:

  • Energy Projects: obtaining permitting and approvals to build, remodel and/or operate various types of infrastructure projects (electricity; petrochemical, etc.)
  • Regulatory advice regarding contaminated soils and waters. In the last 30 years, Todd has advised clients on hundreds of site investigations and remedial work impacting contaminated soils, soil gas, water and sediments. These projects range from State agency cleanups to major federal Superfund sites. The remedial work also extends to related areas such as natural resource damages, compliance with Total Maximum Daily Load requirements for point and non-point sources and related impacts on endangered and threatened species. This work has occurred throughout the United States.
  • Climate Change: advice on California's Global Warming Solutions Act (aka AB 32), cap and trade options and strategies and related federal legislative and regulatory developments.


Todd participates in several trade associations that monitor and comment on proposed federal and state environmental legislation and regulatory developments. Todd has co-authored and contributed to several books focused on international environmental issues, and is a frequent speaker on a variety of environmental subjects. He is counsel to the Board of Directors for the Pacific Basin Consortium for Environmental and Health Studies at the East-West Center.
