    Profile

    Peter Duchesneau’s practice focuses on most aspects of environmental law involving litigation, administrative proceedings, regulatory compliance and business transactions. He handles complex environmental litigation in federal and state courts, including CERCLA, RCRA, Clean Water Act, products liability, toxic tort, and Proposition 65 actions, among others. Mr. Duchesneau has significant experience with emerging chemicals and drinking water contamination.

    In addition to litigation, Mr. Duchesneau counsels clients on regulatory compliance involving such matters as green chemistry, Proposition 65, FIFRA/pesticides, TSCA, RoHS, air quality, climate change, SMCRA, wastewater and hazardous waste; and has successfully represented clients before administrative agencies, including the U.S. Environmental Protection Agency, the California Regional Water Quality Control Board, California Department of Toxic Substances Control, and the South Coast Air Quality Management District. He also advises on corporate and real estate transactions, Brownfields, and environmental due diligence as well as with regard to environmental auditing.

    Prior to being an attorney, Mr. Duchesneau was an engineer with an international environmental consulting firm where he performed work for the U.S. EPA , the California Department of Toxic Substances Control, and DOD, among other clients. He later left consulting to join the corporate environmental management office of a Fortune 100 company where he headed efforts to work with policy-makers in the development of environmental laws and regulations and managed air toxics and Superfund programs.
