Title 16 › CHAPTER 1 — NATIONAL PARKS, MILITARY PARKS, MONUMENTS, AND SEASHORES › SUBCHAPTER LIX–G — CHACO CULTURE NATIONAL HISTORICAL PARK › § 410ii–5
The Secretary must run and protect the Chaco park under this law and the normal laws that apply to National Park units, including the Acts of August 25, 1916 (39 Stat. 535; 16 U.S.C. 1, 2–4) and August 21, 1935 (49 Stat. 666; 16 U.S.C. 461–7). The Secretary must protect, preserve, maintain, and manage the Chaco Culture Archaeological Protection Sites so the cultural resources remain safe and can be studied and explained to the public. Lands held in trust for an Indian tribe or held in restricted fee status stay under their current trust or restricted management. No activities are allowed on the sites’ upper surface that would harm their cultural value. The upper surface includes down to twenty meters below ground level. Subsurface oil, gas, mineral, or coal development is allowed only if done from outside the sites and does not affect that upper surface. Livestock grazing may continue where cooperative agreements exist. Within three complete fiscal years from December 19, 1980, the Secretary must send two plans to the House Committee on Interior and Insular Affairs and the Senate Committee on Energy and Natural Resources: a general management plan (under section 100502 of title 54) and a joint plan for the protection of the archaeological sites, both made by the National Park Service Director in consultation with the Directors of the Bureau of Land Management and Bureau of Indian Affairs and the Governor of New Mexico. The Secretary must also help the Navajo Nation by grant, contract, or cooperative agreement under the Indian Self-Determination and Education Act (Public Law 93–638; 25 U.S.C. 5301 et seq.) for site planning, protection, interpretation, resource management, and development of a Navajo visitor facility.
