REPRESENTATIVE EXPERIENCE
  • Represented Minnkota Power Cooperative and secured a major victory for the client in the U.S. District Court for the District of North Dakota on a U.S. Environmental Protection Agency (EPA) Clean Air Act New Source Review (NSR) enforcement initiative. We settled the NSR case with the EPA and the State of North Dakota with an NSR Consent Decree lodged in federal court in North Dakota. The EPA exercised its dispute resolution rights under the consent decree, and asked the federal district court in North Dakota to require Minnkota to install SCR. On December 21, 2011, the Court ruled against EPA in favor of Minnkota. In September 2011 EPA proposed a rule that would require Minnkota install SCR. After the December 2011 Court Order, EPA agreed not to require SCR in its final regional haze rule.
  • Representation of Fortune 500 energy company in National Environmental Policy Act (NEPA) matter, including cutting edge Environmental Impact Statement air-related matters with the Bureau of Land Management, the EPA, states, and tribes.
  • Representation of several large utilities in siting new coal and natural gas power plants, including Greenhouse Gas (GHG) permitting, Prevention of Significant Deterioration (PSD) permitting, NEPA and EPA advice, and transmission line siting issues.
  • Representation of utilities, refineries, and cement plants in defense of the EPA's New Source Review enforcement actions.
  • Representation of energy companies in expanding oil and gas development, including prevention of PSD permitting, NEPA consultation, endangered species act consultation, and National Historic Preservation Act consultation.
