Under such rules as shall be adopted by the Insurance Commissioner, and notwithstanding other provisions of this chapter, the commissioner is given the authority in the Arkansas Workers' Compensation Insurance Plan to allow the issuance of group or association workers' compensation insurance policies to logging contractors or dealers as sponsors. The policies may, in turn, insure for workers' compensation and employers' liability purposes no fewer than five (5) independent contractors who provide logging services to the sponsoring contractor or dealer. Provided, however, that such association or group coverage be made available on a nondiscriminatory basis to all other industries if the commissioner rules that the coverage is reasonably applicable to that industry and economically sound with respect to the plan.
