  • Ronald J. Tenpas co-chairs Morgan Lewis's Environmental and Climate Change Practices and is also active in the firm's White Collar, Government Relations, and Congressional Investigations Practices. Prior to joining Morgan Lewis, Mr. Tenpas served as the Assistant Attorney General (AAG) for the Environment and Natural Resources Division of the U.S. Department of Justice. In that role, he managed a 700-person division that included 400 attorneys, overseeing civil and criminal litigation arising under more than 150 environmental and natural resources laws. In that capacity, he also advised Cabinet and White House officials on policy and litigation risks associated with the environmental laws. The Division's major client agencies included the Environmental Protection Agency and the Departments of Agriculture, Commerce, Defense, Energy, Homeland Security, and Interior. This included litigation in which regulated entities challenge new regulatory commands, and matters in which the government sought to enforce environmental laws due to alleged civil or criminal violations or sought to recover environmental clean-up costs. These matters typically arise under statutes such as the Clean Air Act, the Clean Water Act, CERCLA (Superfund), RCRA, the Pipeline Safety Act, and others.
