Federal undertaking: NHPA Section 106
54 U.S.C. § 306108 and 36 C.F.R. Part 800 require a federal agency to take effects on historic properties into account before approving, funding, licensing or permitting an undertaking. The process identifies historic properties, assesses effects and seeks resolution through consultation.
Project agreements
When adverse effects are resolved through a memorandum of agreement or programmatic agreement, the document and treatment plan can define avoidance, data recovery, analysis, reporting, curation, public interpretation and consultation duties.
South Carolina review
SHPO participates in federal and certain state review processes. SCIAA maintains archaeological site information, and current South Carolina standards guide professional fieldwork and reporting.
Unauthorized excavation and burial protection
S.C. Code § 16-11-780 addresses unauthorized disturbance of archaeological resources on another's land. S.C. Code § 16-17-600 addresses destruction or desecration of human remains and burial repositories, including Native American burial grounds or mounds.
Beaufort County local review
Beaufort County's published procedure states that Community Development Code Division 5.10 requires development projects to be reviewed for possible impacts to archaeological and historic resources.
Private-land caution
Artifact ownership, permission to excavate and regulatory approval are different questions. Ownership or possession does not eliminate burial protections, permit conditions, local review, federal-undertaking duties or an existing MOA.
Important: National Register eligibility does not by itself create one universal prohibition on private development. The legal effect depends on the governmental action, governing law, local ordinance, permits, agreements, ownership and presence of burials or other protected resources.
