Amends the Act commonly known as the National Park System General Authorities Act to require: (1) the Secretary to notify the Secretary of Defense of the exact military lands included in any study of an area for potential inclusion in the National Park System (NPS); and (2) the Secretary of Defense to evaluate the existing environmental protections for such lands and the importance of such lands to military readiness and preparation. Authorizes the Secretary of Defense to require the Secretary to exclude such lands if it is determined that current environmental protections are adequate and that their inclusion in the NPS would adversely affect military readiness and preparation.
Amends the National Marine Sanctuary Act to prohibit the Secretary from including as a national marine sanctuary any area that the Secretary of Defense has designated for use for military readiness activities.
