Environmental & Natural Resources


Environmental & Natural Resources law is not only complex and constantly evolving, but also highly technical. Michael Best’s team of environmental lawyers understands not only the law and the science of environmental regulations, but also our clients’ business needs and how to help achieve them.

We have more than a century of collective experience in environmental law, assisting with everything from compliance counseling to enforcement defense. Clients know they can count on us to give them strategic, proactive advice in succinct, understandable terms.

Members of our team have served in government, industry, trade associations, and utilities. We maintain relationships with key regulators and legislators at both the state and federal levels, and we work closely with technical staff and environmental consultants and experts. Our experience, approach, and connections enable us to help clients find creative solutions that can transform risk into reward, such as cross-industry emissions agreements or converting waste into energy for sale.

  • Advised the owner/operator of a Wisconsin petroleum refinery on its planned $50 million upgrade. Michael Best assisted in obtaining authorizations and in government relation issues associated with the proposed project. We facilitated meetings with state officials, resulting in an agreed-on approach for expediting and easing the permitting process. We are also defending this client against a Notice of Violation issued under the U.S. EPA’s flaring enforcement initiative, alleging violations of the Clean Air Act. The case involves novel legal theories, many of which have national implications.
  • Defended an investor-owned utility in litigation filed by the U.S. EPA and Sierra Club, alleging Clean Air Act violations at power plants in Wisconsin. Our client owns and operates a fleet of electric generating assets, and the power plants at issue are co-owned with other regulated utilities. We negotiated an approximately $2 billion settlement with the Sierra Club, U.S. DOJ, and EPA, and we continue to represent our client in implementing the settlement agreement.
  • Serve as special counsel to a state government’s Department of Administration, providing environmental compliance representation and regulatory advice related to approximately 50 coal-fired boilers owned and operated by the State. We represented the State in litigation initiated by the Sierra Club, alleging the boilers are in violation of the Clean Air Act. We reached a partial settlement and are assisting with implementation. We also assisted the State with an investigation conducted by U.S. EPA as to the compliance status of these boilers. We work with the State to evaluate environmental regulations and advise on compliance, including the permitting of modifications to heating plants as part of a long-term compliance strategy.
