Case Brief Summary & Legal Analysis
tl;dr: An agency approved exploratory drilling in a grizzly bear habitat without a full environmental impact statement. The court upheld the decision, finding that added mitigation measures could legally reduce the project’s impact to a level of insignificance, satisfying both NEPA and the ESA.
Legal Significance: Establishes that an agency may rely on mitigation measures added to a proposal to justify a Finding of No Significant Impact (FONSI) under NEPA, thereby avoiding the requirement to prepare a full Environmental Impact Statement (EIS).

Case Facts & Court Holding
Key Facts & Case Background
ASARCO, Inc. proposed a four-year exploratory drilling project in the Cabinet Mountains Wilderness Area, a habitat for the threatened grizzly bear. The U.S. Forest Service conducted an environmental assessment and consulted with the Fish and Wildlife Service (FWS) as required by the Endangered Species Act (ESA). The FWS issued a biological opinion initially concluding the project was “likely to jeopardize the continued existence of the grizzly bear” due to cumulative impacts from the drilling and other activities, such as timber sales. However, the FWS also outlined an alternative course of action with specific mitigation and compensation measures designed to “completely compensate” for these adverse effects. These measures included shortening ASARCO’s operating season, rescheduling timber sales, and implementing road closures to enhance habitat security. The Forest Service adopted this comprehensive plan, incorporated it into its final environmental assessment, and approved the drilling project. Based on the modified plan, the agency issued a Finding of No Significant Impact (FONSI), concluding a full Environmental Impact Statement (EIS) was not required under the National Environmental Policy Act (NEPA). Environmental groups challenged this decision, alleging violations of NEPA and the ESA.
