Ga. Code § 25-9-13
The appropriate notice requirements prescribed by Code Section 25-9-6 shall be required of persons performing nonemergency excavations in an area where one or more facility owners or operators has declared extraordinary circumstances in accordance with subsection (d) of Code Section 25-9-7. When a situation of extraordinary circumstances has been declared, the excavator shall be responsible for securing knowledge of the PRIS status of all facility owners or operators in the area to be excavated, as not all facility owners or operators may have declared extraordinary circumstances. Once the PRIS status of all facility owners or operators is known, excavation may commence in accordance with the requirements of subsection (e) of Code Section 25-9-7. If there is visible and obvious evidence of the presence of an unmarked underground facility or sewer lateral of a facility owner or operator that has declared extraordinary circumstances, the excavator shall exercise reasonable care for the protection of such underground facilities and sewer laterals when excavating.
