Representative Experience

Environmental Matters

Art has experience in literally all of the subjects covered by the practice of environmental law including air, water, wetlands and solid and hazardous waste permitting under federal and state environmental laws. He has provided lead responsibility for many major environmental land use disputes as well as transactions involving contaminated property. His experience also includes counseling and, where necessary, defense to targets in civil and criminal environmental enforcement actions.

A list of representative environmental projects in which Art has lead responsibility includes the following:

Energy Matters

Art has a diverse background on representing clients in a variety of energy-related projects. These projects have spanned the broad energy spectrum and include renewable energy projects, bids for base-load generation facilities, power plant facilities, coal-fired power plant projects, hydro-electric projects, negotiation of power purchase contracts and the certification and sale of renewable energy credits. A representative list of his energy projects include the following:

GreenWhey Energy Inc. Project. Represented Geo-Investors Fund on an energy project that will entail the construction and operation of an innovative anaerobic digester facility in Turtle Lake, Wisconsin. It will be one of the largest facilities of its kind in the United States. The digester will process wastewater from local food companies, creating electricity as well as process feed and fertilizer that may be used in local farming operations.

Independent Power Project in Wisconsin. Acted as local counsel representing the equity investors in a co-generation project located in Whitewater, Wisconsin. He had primary legal responsibility for ensuring that all state agency permit and authorizations were required for this facility. This was the first independent power project authorized in Wisconsin. It was a co-generation facility and the host was the University of Wisconsin-Whitewater.

Bio-Mass Facility. Provided all of the legal services to Minergy-Neenah, LLC, the owner operator of a bio-mass, Co-Gen facility located in Neenah, Wisconsin. The fuel source for this facility included dewatered paper mill sludge generated from four area paper mills. The host was a paper mill located adjacent to the facility. His legal services included the negotiation of the power purchase contracts for Minergy in the sale of the green energy generated from the facility to Alliant Energy.

Renewable Energy Credits. Represented a large independent energy producer in the sale of credits from the "Top of the Iowa" wind project in Iowa. The Renewable Energy Credits associated with this project were the first ever certified in Wisconsin under the new Renewable Energy Credit program.

Hosted Energy Bar Association Teleseminar on February 23, 2010, regarding Midwest Wind Development: Perspectives on Current Issues Facing Regional Wind Projects.

U.S. Department of Energy High-Level Waste Repository. Godfrey & Kahn is counsel to a Native American tribe in a proceeding before the Nuclear Regulatory Commission to consider the DOE's application to license the Yucca Mountain high-level waste geologic repository. We petitioned and successfully obtained intervener status for client. An interlocutory appeal of a dispositive issue is currently pending before the Nuclear Regulatory Commission.

Reforestation and Conservation Project, Osa, Costa Rica. As part of its pro bono program, Godfrey & Kahn represented the Natural Resources Foundation of Wisconsin (NRF) in drafting a three-party agreement with NRF, Neenah Paper, Inc. and Friends of the Osa. This innovative agreement covered an annual donation from Neenah Paper in an amount equal to their greenhouse gas offsets from its Wisconsin facilities, as determined by the Chicago Climate Exchange. The annual donation will be used to support a reforestation project on Costa Rica's Osa Peninsula.

Section 48C Credit Applications. Godfrey & Kahn assisted clients in the preparation of various detailed and highly technical applications for allocations of the new Advanced Energy Project tax credits.

Waste to Energy. Godfrey & Kahn was retained by developers of a proposed $150 million waste to energy facility. The proposed facility would use plasma technology to generate renewable energy from municipal solid waste that is currently landfilled.

Tribal Matters

Art has the privilege to represent tribal interests in a broad array of cutting edge environmental and energy projects. He brings his strong background in other non-tribal environmental and energy projects as one of his qualifications for such tribal projects. However, most importantly, his previous tribal client experience has afforded him the privilege to appreciate the role that strong cultural beliefs play in formulating the goals of tribal clients in environmental/energy projects. A representative list of Art's tribal environmental and energy projects include the following:

Tribal Class I PSD Area Designation. Art was part of a professional team representing the Forest County Potawatomi Community ("FCPC"), a federally recognized Tribe in Wisconsin, in its legal effort to obtain Class I designation for its Reservation under the Federal Clean Air Act Prevention of Significant Deterioration ("PSD") program. In 2008, the United States Environmental Protection Agency ("EPA") promulgated a final rule granting the FCPC Class I status for its Reservation in Wisconsin. This was the first Class I designation by EPA for a Tribe granted under the PSD program since 1992.

Crandon Mine Project. Represented the Forest County Potawatomi Community in the Tribe's effort to oppose the application for mining permits under state and federal laws. The proposal involved one of the most significant zinc and copper underground ore deposits in North America. This proposed mining operation precipitated one of the most controversial environmental disputes in the history of Wisconsin. The matter was successfully concluded by the Tribe's innovative buy-out of the applicant's interest in surface and mineral rights associated with the proposed mining project.

Forest County Potawatomi Community. Represented the Forest County Potawatomi Community in the preparation of joint written comments with the National Tribal Environmental Council for filing with the United States Environmental Protection Agency regarding that agency's guidelines for Prevention of Significant Deterioration New Source Review, Refinement of Increment Modeling Procedures (Proposed Rule, 72 F.Reg. 31372-99 (June 6, 2007).

Represented a federally recognized tribe in a confidential engagement to provide an assessment of that tribe's energy/carbon footprint generated by human activities at all of its facilities and mobile sources and provided recommendations for reducing the footprint through a combination of conservation, capital improvements and renewable energy strategies.
