EO 13007 Indian Sacred Sites  

Executive Order 13007 Indian Sacred Sites addresses the accommodation of sacred sites. Each executive branch agency with statutory or administrative responsibility for the management of Federal lands is required, to the extent practicable, permitted by law, and not clearly inconsistent with agency functions, accommodate access to and ceremonial use of Indian sacred sites by Indian religious practitioners. They shall also avoid adversely affecting the physical integrity of the sacred sites. Where appropriate, agencies will maintain the confidentiality of sacred sites.
