Experience & Results
  • Danielle provides strategic advice to clients about what to anticipate when working with federal agencies to advance projects on public lands and how to work through challenges. She is familiar with the procedures involved in federal oil and gas leasing and permitting, authorization of renewable energy and transmission rights-of-way on public lands, and approval of hardrock mining plans of operation. Danielle understands the factors that influence agency decision-making, including analysis of potential impacts to resources and resource uses, the roles of Tribal and interagency consultation and public involvement, and the constraints and opportunities of the federal and state legal framework.
  • Danielle is adept at analyzing complex resource challenges that arise from the layered directives in agency regulations and guidance, executive policies, federal resource and environmental statutes (Federal Land Policy and Management Act, Mineral Leasing Act, Indian Mineral Development Act, General Mining Law, Endangered Species Act, Clean Air Act, and Clean Water Act) and state laws. She assists clients in their analysis and planning for proposing projects on federal or tribal lands and guides them in working with agencies to refine and improve project proposals. Danielle also helps clients with participation in public comment opportunities during agency decision-making that affects their interests, such as rulemakings, resource management plans, and project proposals.
  • When clients are adversely affected by agency decisions, Danielle represents them in seeking administrative or judicial review. She also represents clients in defending project-approval or rulemaking decisions challenged by other parties. Her litigation experience includes defending agency planning, leasing, and permitting decisions in cases involving impacts to greenhouse gases and climate, air quality, water quality, wildlife habitat, wilderness values, areas of critical environmental concern, and recreation. She has defended federal enforcement orders and has represented regulated entities in CERCLA and state environmental compliance proceedings. She counsels clients in evaluating whether settlement advances their interests, and is a trusted advisor in negotiating workable solutions that avoid or curtail litigation.
