 The 1992 amendment to the National Historic Preservation Act established "Properties of traditional religious and cultural importance to an Indian tribe or Native Hawaiian organization" (Section 101(d)(6) of the National Historic Preservation Act of 1966, as amended in 1992).Thus, Congress established this classification expressly for Native American Tribes and Native Hawaiian organizations.The amendment was clear and explicit, and it did not say anything about any other cultural groups or entities.
