(a) Any person who knows or reasonably believes that any human burials or human skeletal remains are being or about to be disturbed, destroyed, defaced, removed or exposed shall immediately notify the Chief Medical Examiner and State Archaeologist of such fact. If human burials or human skeletal remains are encountered during construction or agricultural, archaeological or other activity that might alter, destroy or otherwise impair the integrity of such burials or remains, the activity shall cease and not resume unless authorized by the Chief Medical Examiner and the State Archaeologist provided such authorization shall be made within five days of completion of the investigation of the Chief Medical Examiner pursuant to subsection (b) of this section.

(b) After notification under subsection (a) of this section, the Chief Medical Examiner shall determine if the remains represent a human death required to be investigated under § 19a-406. After completion of his investigation, if the Chief Medical Examiner determines that the remains may be the remains of a Native American or were found in the subsurface and buried for more than fifty years, the Chief Medical Examiner shall notify the State Archaeologist of such fact. The State Archaeologist, upon such notification, shall in consultation with the Department of Economic and Community Development, the Native American Heritage Advisory Council, established under § 10-382, the Commissioner of Energy and Environmental Protection, and the landowner determine, within seventy-two hours, if the site where such remains were discovered can be preserved in situ and protected by a preservation restriction as defined in § 47-42a.

(c) If in situ preservation is not prudent and feasible or not agreed to by the landowner, the State Archaeologist, upon consultation with the landowner and, if appropriate, the Native American Heritage Advisory Council, the Department of Economic and Community Development, and the Commissioner of Energy and Environmental Protection shall, if feasible, provide for removal and reburial of the remains at another location or for additional archaeological investigations and scientific analysis prior to reburial. Any excavation and recovery of remains by the State Archaeologist shall be completed not more than five business days after notification by the Chief Medical Examiner under this section unless the landowner consents to additional days.

(d) Human skeletal remains discovered during archaeological investigation shall be excavated under the supervision of the State Archaeologist, pursuant to a written agreement between the State Archaeologist and the holder of the permit specifying the excavation, methods to be used and data to be collected. Due care shall be exercised during excavation, subsequent transport and storage of skeletal remains to insure that the sacred meanings of the remains for Native Americans are respected and protected.

(e) The provisions of this section shall not be construed to require the owner of private lands on which human skeletal remains are found to pay the costs of excavation, removal analysis or reburial of such remains.
