All bills introduced authorizing the promulgation of a rule may be referred by the President of the Senate and by the Speaker of the House of Delegates to appropriate standing committees of the respective houses for further consideration or the matters may be otherwise dealt with as each house or its rules provide. The Legislature may, by act, authorize the agency to adopt a legislative rule incorporating the entire rule or may authorize the agency to adopt a rule with any amendments adopted by the Legislature. The clerk of the house originating the act shall immediately file a copy of any bill of authorization enacted with the Secretary of State and with the agency proposing the rule and the clerk of each house may prepare and file a synopsis of legislative action during any session on any proposed rule submitted to the house during the session for which authority to promulgate was not by law provided during the session. In acting upon the separate bills authorizing the promulgation of rules, the Legislature may, by amendment or substitution, combine the separate bills of authorization insofar as the various rules authorized in the amendment or substitution are proposed by agencies which are placed under the administration of one of the single, separate executive departments identified under the provisions of §5F-1-2 of this code or the Legislature may combine the separate bills of authorization by agency or agencies within an executive department. In the case of rules proposed for promulgation by an agency which is not administered by an executive department pursuant to the provisions of §5F-1-2 of this code, the separate bills of authorization for the proposed rules of that agency may, by amendment or substitution, be combined. These provisions relating to combining separate bills of authorization according to department or agency are not intended to restrict the permissible breadth of bills of authorization and do not preclude the Legislature from otherwise combining various bills of authorization which have a unity of subject matter. Any number of provisions may be included in a bill of authorization, but the single object of the bill shall be to authorize the promulgation of proposed legislative rules.
