If the Coroner, with the aid of anarchaeologist, determines that the remains are prehistoric, they are required to contact the NativeAmerican hleritage Commission (NAHC). The NAHC is responsible for designating the most likely

ultimate disposition of the remains, as required bySection 7050.5 of the California Health and SafetyCode. The MLD is required to make theirrecommendation within 48 hours of being grantedaccess to the site.

American burials (California hlealth and Safety
