Mark A. Thimke is a partner and environmental lawyer with Foley & Lardner LLP. His practice encompasses all major environmental programs, including hazardous waste, Superfund, the Clean Air Act, air toxics, and wastewater. Mark has been involved in Superfund matters ranging from landfills, municipal well fields, and the investigation and cleanup of river and harbor sediment remediation areas, representation of dischargers on issues involving water toxics limitations, and the development of a detailed anti-degradation policy, and work on several major air enforcement actions. He is a member of the firm’s Environmental Regulation Practice and the Energy Industry Team.
Mark helped secure the first Plantwide Applicability Limit (PAL) permit in Wisconsin, for Bemis Co. Inc. A PAL permit applies an annual emissions limit for pollutants to an entire facility, eliminating the need for multiple limits throughout the facility and more crucially, allowing companies to avoid going through the time-consuming NSR permitting process each time it expands operations.
