Experience
Solutions in action
Clean Power Plan
In February 2016, Todd was one of 30 lawyers representing 29 U.S. states and state agencies who signed onto a brief on behalf of the Mississippi Public Service Commission obtaining a stay of the federal Clean Power Plan from the U.S. Supreme Court in a 5-4 decision. The Clean Power Plan sets the first national carbon emission limits for U.S. electric power plants. The decision marked the first time a U.S. Supreme Court has ever granted such a motion in its history.
PFAS and emerging contaminants
Todd has significant experience advising clients on PFAS and emerging contaminant litigation and regulatory issues. His 34 years of experience includes counseling on one of the highest-profile PFAS contamination sites in Wisconsin, counseling an international corporation on PFAS issues and numerous cleanup/cost recovery actions involving other contaminates.
Precedent-setting work
Todd successfully represented Wisconsin industrial and utility interests in a precedent-setting challenge to the U.S. Environmental Protection Agency (US EPA)’s rule to restrict the transport of pollution. He also defended enforcement claims jointly prosecuted by the State of Wisconsin and the US EPA resulting in a precedential decision defining the limitations of the government’s Clean Air Act enforcement powers in United States v. Murphy Oil USA, Inc.
Climate change regulations and litigation
Todd served as special counsel to the State of Wisconsin providing litigation representation and regulatory advice related to the environmental compliance of approximately 50 coal-fired boilers owned and operated by the state. These boilers are used to supply heat, and in some cases electricity, to institutional facilities owned and operated the University of Wisconsin system and other state agencies.
With many states prioritizing climate change, the federal and various state/regional governments have developed multiple regulations restricting the carbon intensity of power production. Todd has worked with the State of Wisconsin and University of Wisconsin System to deal with these regulatory changes and defend them in federal court all while evaluating cost-effect compliance strategies under Clean Air Act rules. Todd also provided assistance in the permitting of new and modified units at many campuses.
This high-profile project was precipitated by lawsuits filed by the US EPA, Sierra Club and even the State of Wisconsin against sister state agencies. The project involves defending against state and federal government and environmental groups which are empowered under federal law to enforce federal law while, from a regulatory standpoint, dealing with the myriad of rules putting pressure on coal-fired boilers.
Petroleum refineries and flaring enforcement
Todd’s client Calumet Superior LLC operates a petroleum refinery located in Superior, Wisconsin. The US EPA has targeted this refinery under the Agency’s flaring enforcement initiative. Todd has been defending Calumet against novel and unprecedented legal enforcement theories, many of which have national implications.
Tribal Air Coalition
Todd represents a coalition of ten large manufacturing/mining entities in a process whereby Native American tribes are seeking to exercise their authority under the Clean Air Act to re-designate their respective reservations to a restrictive “Class I” air quality designation. This action may restrict off-reservation air pollution sources whose emissions may adversely affect the tribal Class I area. This is a novel regulatory development and Todd’s work is receiving national attention.
Negotiating settlements
Madison Gas & Electric (MGE) owns and operates a fleet of electric generating assets in Wisconsin. Some of those units are co-owned with other regulated utilities. Todd represented Madison Gas & Electric in litigation filed by the US EPA and Sierra Club alleging Clean Air Act violations at the co-owned power plants located in the State of Wisconsin. On behalf of MGE, Todd ultimately negotiated settlement terms with the Sierra Club, U.S. Department of Justice and US EPA. The total value of the settlement was approximately $2 billion. Todd continues to represent MGE in implementing the settlement agreement.
