§ 135. Rules and regulations. The commissioner is hereby authorized, after public hearing, to adopt and promulgate such rules and regulations to supplement and give full effect to the provisions of this article as he may deem necessary, provided, that the commissioner may adopt and promulgate, insofar as appropriate, without public hearing, any rules and regulations promulgated under any federal act or acts or change or amend the regulations promulgated hereunder so as to conform, insofar as appropriate, to those promulgated under such federal act or acts. The commissioner may, if he or she determines that the protection of the consumers of the state is not impaired by such action, provide by regulation for exemption from registration of small feed distributors when he or she finds that such an exemption would avoid unnecessary regulation and assist in the administration of the article without impairing such article's purpose.
