As amended, Section R612-400-3 provides a clear statement of its purpose, scope and authority. The section then establishes definitions of several terms, notably the term "acceptable credit rating agency", and also consolidates within the rule other existing definitions that were found elsewhere in Division rules. The section's substantive provisions are also reorganized for clarity and to conform to the Division's existing practice in consideration of applications to self-insure. In particular, the section is subdivided into subsections that correlate with the various steps and requirements of the self-insurance process. Finally, the section adds a requirement that applicants for authorization to self-insure must designate an agent for service of notices and orders, and sets forth the process by which an applicant can challenge a Division denial or revocation of self-insured status.
