Nothing in these regulations shall be construed to require any rating organization or member or subscriber insurer to refile any rates in effect. Any member or subscriber to a licensed rating organization is authorized to continue to use all rates and deviations in effect until such time as these rates are disapproved, replaced, or modified or the insurer submits an independent filing to change its rates or files a reference filing form adopting the rating organization's prospective loss costs, or modification of them.
