(B) The agency shall determine whether a principle of law or policy thus identified has a general and uniform operation and establishes a legal regulation or standard that would not exist in its absence. If the principle of law or policy has these characteristics, the agency shall determine whether the principle of law or policy should be supplanted by its restatement in a rule to achieve one or more of the following as they are relevant to the principle of law or policy:

1. (1) Assert the general and uniform operation of the principle of law or policy;
2. (2) Make the principle of law or policy more readily available to the public;
3. (3) Make the principle of law or policy more readily available to persons who specifically are affected by the principle of law or policy;
4. (4) Enable the principle of law or policy to be better known in advance of its application;
5. (5) Enable greater public participation in improvement and further development of the principle of law or policy;
6. (6) Enable greater participation by persons specifically affected by the principle of law or policy in the improvement and further development of the principle of law or policy;
7. (7) Make the principle of law or policy more easily understandable; or
8. (8) Make the principle of law or policy more readily available to those legally charged with monitoring or reviewing the agency's operations. If a principle of law or policy aids in the interpretation of an existing rule or statute, the agency shall consider whether the aiding effect clarifies or otherwise resolves an uncertainty in the existing rule or statute. If the principle of law or policy can be so characterized, the agency shall consider whether the principle of law or policy should be supplanted by its restatement in an interpretive rule. The agency may not presume that a principle of law or policy that aids in the interpretation of an existing rule or statute is simply a reiteration of the existing rule or statute.
