§ 258-q. Action for a uniform northeast market. The commissioner is hereby authorized and directed to act independently or through the Northeastern Association of State Departments of Agriculture, the National Conference on Interstate Milk Shipments and any other group or agency, to achieve uniformity of laws and regulations involving inspection of farms and plants, sanitary codes, labeling of dairy products and their imitations, standards for dairy products, licensing of milk dealers and the terms of both federal and state milk marketing orders in effect in the area. He is further directed to work toward the elimination of the unnecessary and costly barriers to the free flow of milk created by laws and regulations originally enacted to help the income of dairy farmers but whose present effect is to interfere with the free flow of milk and to reduce the efficiency of distribution. The commissioner will continuously endeavor to effectuate the purpose of this section by seeking uniform laws and regulations, joint investigations, joint hearings, and joint and concurrent orders and regulations. He further will endeavor to create a joint agency or joint agencies to carry out and enforce joint and concurrent orders and any other joint activities.
