# §1000.1390. Is the Secretary required to take into account the Indigenous Knowledge of Tribes/Consortia when preparing environmental studies under NEPA, NHPA, and related provisions of other law and regulations?


Yes, Council on Environmental Quality (CEQ) regulations direct agencies to make use of high-quality information including reliable data and resources, models, and Indigenous Knowledge, in carrying out their responsibilities under NEPA. The Secretary recognizes that Tribes/Consortia hold relevant information and perspectives regarding the environment, and Indigenous Knowledge can inform the Secretary's environmental analysis. Similarly, [section 106](/cfr/25/106.md) of NHPA ([54 U.S.C. 306108](/usc/54/306108.md)) establishes a process to ensure that the Secretary take into account the effects of a project the Department carries out, licenses, or assists on historic properties.
