Ga. Code § 50-27-81.1
The corporation shall by rule and regulation create a process whereby any person may request an official interpretation of any rule or regulation through a regulatory guidance letter. A regulatory guidance letter shall be issued within 60 days of a request seeking guidance on a rule or regulation and shall only be used to interpret or clarify existing rules and regulations. A regulatory guidance letter shall remain in effect and be valid unless it is superseded by a subsequently adopted state law or a rule or regulation of the corporation, a subsequently issued regulatory guidance letter, or a court order. The corporation shall incorporate relevant portions of any regulatory guidance letter in subsequent rules and regulations as may be applicable and necessary to ensure clarity in such rules and regulations.
