NORTH CAROLINA OFFICE OF STATE ARCHAEOLOGY ARCHAEOLOGICAL INVESTIGATION STANDARDS AND GUIDELINES FOR BACKGROUND RESEARCH, FIELD METHODOLOGIES, TECHNICAL REPORTS, AND CURATION -December 2017- About the North Carolina Office of State Archaeology The North Carolina Office of State Archaeology (OSA) was created by the North Carolina General Assembly in 1973 to coordinate and implement a statewide archaeological preservation program. Elements of this program include maintaining a statewide computer-based inventory of archaeological sites, enforcing the North Carolina Archaeological Resource Protection Act (G.S. 70 Article 2), and ensuring the proper treatment of human burials in cooperation with the individuals and organizations specified in the Unmarked Human Burial and Human Skeletal Remains Protection Act (G.S. 70 Article 3). An important aspect of North Carolina’s statewide archaeological preservation program is to implement the policies of the National Historic Preservation Act of 1966, as amended, and later, North Carolina General Statute 121-12a. G.S. 121-12a provides for consideration of National Register properties in undertakings funded or licensed by the state.
